History of the University of Indonesia

The University of Indonesia is a modern, comprehensive, open, multicultural, and humanist campus that covers a broad range of disciplines. UI is currently simultaneously trying to become one of the leading research universities or academic institutions in the world. As a research university, efforts to achieve the highest achievements in terms of discovery, development, and diffusion of knowledge regionally and globally are always carried out. Meanwhile, UI has also deepened its commitment to its efforts in the field of academic development and research activities through a number of disciplines within its scope.

History The forerunner of the University of Indonesia began in 1849 and the University of Indonesia is a representative educational institution with the oldest history in Asia. Having produced more than 400,000 alumni, Universitas Indonesia continues to play an important role at the national and world levels. However, UI cannot escape from its current mission of becoming a high-quality educational institution, world-standard research, and maintaining prestige standards in a number of international journals.

Dutch Occupation Period (1849-1946)
The Dutch Colonial Government 1849 built a university which was later named Dokter-Djawa School (School of Medicine for Javanese) in January 1851, this high school specializing in medical science.

After experiencing a name change at the end of the 19th century, in 1898 to be precise, the name Dokter-Djawa School changed to School tot Opleiding van Indische Artsen (School of Medicine for Indigenous Doctors) or STEVIA. For 75 years STEVIA served as the best educational place for aspiring doctors in Indonesia before it was closed in 1927.

However, a medical school was later built together with four other high schools in several cities in Java. The high schools were Technische Hogeschool te Bandoeng (Faculty of Engineering) which was established in Bandung in 1920, Recht Hoogeschool (Faculty of Law) in Batavia in 1924, Faculteit der Letteren en Wijsbegeerte (Faculty of Literature and Humanities) in Batavia in 1940, and a year later they were built Faculteit van Landbouwweteschap (Faculty of Agriculture) in Bogor.

These five high schools were the pillars in creating the Good-Universiteit (Emergency University), which was founded in 1946.

Doctor Java School
Age of Independence (1947-the 1960s)
Nood-universiteit changed its name to Universiteit van Indonesie in 1947 and was based in Jakarta. Several nationalist professors, one of whom is Prof. Mr. Djokosoetono, continued his function as a lecturer for Universiteit van Indonesia in Yogyakarta, then the nation's capital.

The Indonesian capital then returned to Jakarta in 1949 after the Dutch recognized the sovereignty of the Republic of Indonesia. Universiteit van Indonesia Yogjakarta also moved again to Jakarta.

Universiteit van Indonesië was later merged into "Universiteit Indonesia" in 1950. This university has a Faculty of Medicine, Law, Letters, and Philosophy in Jakarta, a Faculty of Engineering located in Bandung, a Faculty of Agriculture in Bogor, a Faculty of Dentistry in Surabaya, and a Faculty of Economics in Makassar.

Faculties outside Jakarta then developed into separate universities between 1954-1963. The University of Indonesia in Jakarta has a campus in Salemba and consists of several faculties such as Medicine, Dentistry, Mathematics and Natural Sciences, Literature, Law, Economics, and Engineering.

In subsequent developments, the Faculty of Psychology, Faculty of Social and Political Sciences, Public Health, Computer Science, and then the Faculty of Nursing were established.

Doctor Java School
Modern Age (1970s-present)
Before the University of Indonesia campus in Depok was built in 1987, the University of Indonesia had three campus locations namely in Salemba, East Pegangsaan, and Rawamangun. After the new campus was established on 320 hectares of land in Depok, the Rawamangun campus was moved while the Salemba campus was still maintained for the Faculty of Medicine, Dentistry, and Postgraduate Programs.

Not long after 2000, the University of Indonesia became one of several universities with the status of a State Owned Legal Entity in Indonesia. This change in status brought significant changes to the University of Indonesia, namely greater autonomy in academic development and financial management so that the university grew to become a world-class university.

From this historical perspective, the University of Indonesia has grown progressively into an institution that aims to become a leader in the fields of humanity and civilization by balancing academic values, morality, and art. Through these advantages, the University of Indonesia intends to turn the Indonesian nation into a more prosperous and democratic society, with a focus on peace, justice, and strong environmental values.

History of Mount Krakatau Indonesia

sejarah gunung krakatau
In the beginning, the big island of Krakatau, which we usually call by the name of Mount Krakatau, was a mountain (ancient Mount Krakatau) which has a height of about 2000 meters above sea level with a circle of beaches of about 11 km and a radius of about 9 km2.

However, the devastating explosion that occurred around 416 AD destroyed three-quarters of the body of the mountain and left three large islands, namely Sertung Island, Rakata Island and Panjang Island, as well as a caldera in the middle of the three islands. Before 1883, two clusters of mountains appeared, named Mount Danan and Mount Perbuatan, which later united with Rakata Island and were commonly referred to as Mount Krakatau.

In 1880, the so-called Strombolian period, volcanic activity continued for several months, and Mount Perbuatan actively spewed lava. After that period, there was no volcanic activity until finally signs of an impending eruption appeared in May 1883.

Then on August 27, 1883 Mount Krakatau erupted. According to historical records, which until now have always been promoted by Lampung tourism ranks, Mount Krakatau erupted very violently, shaking the world. eruptions of lava and ash reached a height of 80 km. While the ashes surround the earth for several years. seen from North America and Europe, at that time the sun looks blue and the moon looks orange (orange).

This volcanic eruption produces great dust that can penetrate a distance of up to 90 km. The eruption also had an impact on sea waves up to 40 m vertically and has claimed around 36,000 lives in 165 villages both in South Lampung and west of West Java. And because of the eruption it has obliterated Mount Danan and Perbuatan from the face of the earth and left three islands namely Panjang Island, Sertung Island, and Rakata Besar Island as well as a caldera which is located in the middle of the three islands with a diameter of 7 km.

Forty years later a new miracle was born. Around 1927 the fishermen who were going to sea in the Sunda Strait were suddenly surprised. A plume of black smoke on the surface of the sea immediately appeared between the three islands, namely in the caldera, which was the site of the previous violent eruption. Then on December 29, 1929 a crater wall appeared to sea level which was also the source of the eruption. Only two years after the mysterious puff of smoke in the sea, then a strange object appeared. The original "face" of this strange object became clearer and clearer day by day and it turned out that it was what was later called Mount Anak Krakatau.

But the mystery of Mount Anak Krakatau doesn't end there. This mountain has its own uniqueness, because this mountain always adds about one inch in height every day. Mount Anak Krakatau, which was originally only a few meters away, can now reach 230 meters above sea level and has since appeared in 1927. This mountain was recorded to have erupted about 16 times from December 1927 to August 1930 and 43 times from 1931-1960 and 13 times from 1961-2000.

History of the Kutai Kingdom in East Kalimantan

kerajaan-kutai
The Kutai Kingdom is the oldest kingdom in Indonesia. This kingdom is located on the banks of the Mahakam river in Muarakaman, East Kalimantan, near the town of Tenggarong.

Dynasty Founder
It is estimated that the Kingdom of Kutai was founded in the 4th century AD. The inscription was erected by King Mulawarman. Historical evidence about the Kutai kingdom is the discovery of seven inscriptions in the form of yuba (stone pillars) written on yuba using Pallawa letters and Sanskrit.

The contents of the inscription stated that the first king of the Kingdom of Kutai was named Kudungga. He has a son named Asawarman who is referred to as wamsakerta (family maker). After he died, Asawarman was replaced by Mulawarman. The use of the name Asawarman and the names of the kings in subsequent generations shows that the influence of Hindu teachings had entered the Kutai kingdom and this proves that the Kutai kings were native Indonesians who had embraced Hinduism.

Kingdom Life
Social life in the Kingdom of Kutai is a translation of the inscriptions found by experts. Among these translations are the following:
- Society in the Kingdom of Kutai is organized, orderly and orderly
- People in the Kingdom of Kutai have the ability to adapt to foreign cultures (India) and follow the changing patterns of the times while maintaining and preserving their own culture.

Economic life in the Kingdom of Kutai can be known from the following two things:
The geographical location of the Kutai Kingdom is on the trade routes between China and India. The Kingdom of Kutai became an interesting place for merchants to stop by. This shows that trading activities have become part of the life of the Kutai people, in addition to agriculture.

Written information on the inscription says that King Mulawarman once gave his wealth in the form of oil and 20,000 cows to the Brahmins.

The cultural life of the Kutai people is as follows:
- The people of Kutai are people who maintain the roots of their ancestral cultural traditions.
- People who are very responsive to changes and cultural progress.
- Uphold religious spirit in their cultural life.

Entry of Cultural Influence
The influx of Indian cultural influence into the archipelago caused Indonesian culture to change. The most important change is the emergence of a government system with a king as its head. Before Indian culture entered, the government was only led by a tribal chief.

Apart from that, another mix-up is the life of the ancestors of the Indonesian people who built stone monuments. This habit shows that in accepting foreign cultural elements, the Indonesian people are active. This means that the Indonesian people are trying to find and adapt these foreign cultural elements to their own culture.

The Indonesian people have a habit of erecting stone monuments, called menhirs, for the worship of ancestral spirits, while the stone monuments (Yupa) erected by King Mulawarman are used to tie up sacrificial animals.

The inscription also tells that King Mulawaraman ruled wisely. He once presented ± 20,000 cows for sacrifice to brahmins/priests. And the inscription also stated that King Aswawarman was the founder of the dynasty, why wasn't his father Kudungga the founder of the dynasty but his son Aswawarman? This was because at that time King Kudungga had not embraced Hinduism, so he could not become the founder of the Hindu dynasty.

From King, Aswawarman descended to Mulawarman, because Mulawarman also embraced Hinduism. This is known from the mention of the sacred building for God Trimurti. The building is called the Wapraskewara building and in the Kembeng Cave in the interior of Kutai, there are a number of Hindu religious statues such as Shiva and Ganesha.

Legacy Evidence
Historical evidence of the Kutai Kingdom is the discovery of seven inscriptions in the form of Yupa (stone pillars)

History of the Kingdom of Kediri

The Kingdom of Kediri is a large kingdom in East Java that was founded in the 12th century. This kingdom is part of the Ancient Mataram Kingdom. The center of his empire was located on the banks of the Brantas River, which at that time had become a busy shipping lane.

Establishment of the Kingdom of Kediri
The discovery of the Tondowongso Site in early 2007, which is believed to be a relic of the Kingdom of Kediri, is expected to help provide more information about the kingdom. Several ancient statues from the Kingdom of Kediri. The statue found in Gayam village, Kediri is classified as rare because it is the first time a statue of the four-faced or Catur Muka Shiva god Shiva has been found.

In 1041 or 963 AD King Airlangga ordered the dividing of the kingdom into two parts. The division of the kingdom was carried out by a Brahmin who was known for his supernatural powers, namely Mpu Bharata. The two kingdoms known as Kahuripan became Jenggala (Kahuripan) and Panjalu (Kediri) which were bounded by Mount Kawi and the Brantas river were told in the Mahaksubya inscription (1289 AD), the book Negarakertagama (1365 AD), and the Calon Arang book (1540 AD). The purpose of dividing the kingdom into two is to avoid conflict.

The Jenggala Kingdom covered the Malang area and the Brantas river delta with its ports in Surabaya, Rembang, and Pasuruhan, the capital city being Kahuripan, while Panjalu was later known as Kediri including Kediri, Madiun and the capital city Daha. Based on the inscriptions found, each kingdom felt entitled to the entire throne of Airlangga, so war broke out.

At the end of November 1042, Airlangga was forced to divide his kingdom because his two sons competed for the throne. A son named Sri Samarawijaya got a western kingdom called Panjalu which was centered in a new city, namely Daha. Meanwhile, the son named Mapanji Garasakan got an eastern kingdom named Janggala which was based in the old city, namely Kahuripan. Panjalu was controlled by Jenggala and the name of Raja Mapanji Garasakan (1042-1052 AD) was immortalized in the Malenga inscription. He still wears the symbol of the Kingdom of Airlangga, namely Garuda Mukha.

At first, the civil war was won by Jenggala but in the subsequent developments, it was Panjalu/Kediri who won the war and controlled the entire throne of Airlangga. Thus in East Java stood the kingdom of Kediri where evidence explaining this kingdom, in addition to the discovery of inscriptions also through literary books. And what explains a lot about the Kediri kingdom is the work in the form of literary books. The result of this literary work is the book Kakawin Bharatayudha written by Mpu Sedah and Mpu Panuluh which tells about the victory of Kediri/Panjalu over Jenggala.

Development of the Kingdom of Kediri
In its development, the Kingdom of Kediri, which had the capital of Daha, grew to a large extent, while the Kingdom of Jenggala sank. Allegedly the Kingdom of Jenggala was conquered by Kediri. However, the loss of Jenggala traces may also be due to the absence of inscriptions left behind or the inscriptions left by the Jenggala Kingdom that have not been found. The glory of the Kingdom of Kediri had fallen when King Kertajaya (1185-1222) clashed with the clergy. Akuwu Tumapel Tunggul Ametung took advantage of this situation.

But then his position was taken by Ken Arok. It was in this former Kediri Kingdom that Ken Arok later founded the Singasari Kingdom, and Kediri came under Singasari's rule. When Singasari was under the reign of Kertanegara (1268-1292), there was an upheaval within the kingdom. Jayakatwang, the king of Kediri who had been submissive to Singasari, joined forces with the Regent of Sumenep (Madura) to bring down Kertanegara. Finally, in 1292 Jayakatwang succeeded in defeating Kertanegara and rebuilding the glory of the Kediri Kingdom.

The political development of the kingdom of Kediri
Mapanji Garasakan reigned shortly. He was succeeded by King Mapanji Alanjung (1052 – 1059 AD). Mapanji Alanjung was later replaced again by Sri Maharaja Samarotsaha. The continuous fighting between Jenggala and Panjalu resulted in no clear news about the two kingdoms for 60 years until the name of King Bameswara (1116 – 1135 AD) from Kediri emerged.

At that time the capital city of Panjalu had been moved from Daha to Kediri so this kingdom was better known as the Kingdom of Kediri. King Bameswara wore a royal badge in the form of a fanged skull above the crescent moon which is commonly called Candrakapala. After Bameswara stepped down from the throne, he was replaced by Jayabaya, who during his reign succeeded in defeating Jenggala. Successively the kings of Kediri since Jayabaya were as follows.

In 1019 AD Airlangga has crowned the king of Medang Kamulan. Airlangga tried to restore Medang Kamulan's authority, after the royal authority was restored, Airlangga moved the center of government from Medang Kamulan to Kahuripan. Thanks to his hard work, Medang Kamulan achieved glory and prosperity. Towards the end of his life, Airlangga decided to resign from the government and became a hermit known as Resi Gentayu. Airlangga died in 1049 AD.

The heir to the Medang Kamulan royal throne should be a daughter, namely Sri Sanggramawijaya who was born from a consort. However, because he chose to become a hermit, the throne was passed to Airlangga's son who was born from a concubine.

To avoid civil war, Medang Kamulan was divided into two, namely the kingdom of Jenggala with the capital Kahuripan, and the kingdom of Kediri (Panjalu) with the capital D haha. But the effort failed. This can be seen until the 12th century when Kediri remained a fertile and prosperous kingdom but was not completely peaceful due to the overshadowing of Jenggala which was in a weaker position. It made a dark atmosphere, full of hypocrisy, and murder took place against princes and kings between the two countries. However, this feud ended in the defeat of Jenggala, and the kingdom was reunited under the rule of Kediri.

KEDIRI KINGDOM GOVERNMENT SYSTEM
The government system of the Kediri kingdom saw several changes of power, while the kings who had ruled during the Kediri kingdom were: Shri Jayawarsa Digjaya Shastraprabhu.

Jayawarsa was the first king of the Kediri kingdom with an inscription dated 1104. He called himself the incarnation of Vishnu.

Kameshwara
The second king of the Kediri kingdom who had the title Sri Maharajarake Sirikan Shri Kameshwara Sakalabhuwanatushtikarana Sarwwaniwaryyawiryya Parakrama Digjayottunggadewa, better known as Kameshwara I (1115-1130). His royal symbol is a fanged skull called Candrakapala. During his reign, Mpu Darmaja changed the Samaradana book. In this book, the king is praised as the incarnation of the god Kama, and his capital whose beauty the whole world admires is named Dahana. His consort was named Shri Kirana, who came from Janggala.

Jayabaya
The third king of Kediri, who holds the title Shri Maharaja Shri Kroncarryadipa Handabhuwanapaka Parakramanindita Digjayotunggadewanama Shri Gandra. With his inscription in 1181. The most famous King of Kediri was Prabu Jayabaya, under his reign Kediri achieved glory. Jayabaya's expertise as an accomplished political leader is famous for his predictions. These predictions are collected in one book entitled Jongko Joyoboyo. The spiritual and material support from Prabu Jayabaya and cultural and literary matters were unmitigated. His people's attitude and far-reaching vision made Prabu Jayabaya worth remembering.

King Sarwaswera
As a religious and culturally devout king, Prabu Sarwaswera adhered to the principle of that wam asi, which means you are you, you are (all of them), and all creatures are you. According to Prabu Sarwaswera, the ultimate goal of human life is moksha, namely the unification of the soul with Paramatma. The right path is that which leads to oneness, anything that hinders oneness is not right.

King Kroncharyadipa
His name means fortress of truth, the Prabhu always does justice to his people. As devout religious people control themselves from their government with the principle, sad kama wrath, namely six kinds of enemies in human beings. The six are Croda (angry), moha (confusion), kama (lust), loba (greedy), Mada (drunk), masarya (envy).

Srengga Kertajaya
Srengga Kertajaya never stops working hard for the sake of his nation. He hopes for a safe and peaceful society. Prabu Srengga's principle of sanctity, according to the wayang puppeteers, was described by Prapanca.

Kertajaya Government
The last king was during the Kediri period. Kertajaya is a noble king and really cares about the people. Kertajaya is known for its chess clan which means four roads, namely dharma, arta, kama, moksa.

The social life of the people of the kingdom of Kediri
The social life of the Kediri people is quite good because the welfare of the people has increased, and the people live in peace, this can be seen from the people's houses which are good, clean and neat, and have yellow and green tiled floors and the Kediri people have worn cloth to the bottom. knee. With a safe and peaceful community life, art can develop, among other things, the most advanced literature is literary art. This can be seen from the many literary results that you can know until now.

The literary results, apart from what has been described in the description of the previous material, there are also many other literary books, such as the Hariwangsa and Gatotkacasraya books written by Mpu Panuluh during the Jayabaya period, the Simaradahana book by Mpu Darmaja, the Lubdaka and Wertasancaya books by Mpu Tan Akung, the book Mpu Triguna's Kresnayana and the Sumanasantaka book by Mpu Monaguna. Everything was produced during the reign of Kameswara.

The discovery of the Tondowongso Site in early 2007, which is believed to be a relic of the Kadiri Kingdom, is expected to help provide more information about the kingdom. Several ancient statues from the Kingdom of Kediri. The statue found in Gayam village, Kediri is classified as rare because it is the first time a statue of the four-faced or Catur Muka Shiva god Shiva has been found.

We can see the social life of the people at the time of the Kediri Kingdom in the book Ling-Wai-Tai-Ta compiled by Chou Ku-Fei in 1178 AD. The book states that the people of Kediri wore cloth up to below their knees and their hair was loose. The houses are usually very clean and tidy. The floor is made of yellow and green tiles.

His government was very concerned about the condition of its people so agriculture, animal husbandry, and trade progressed quite rapidly. The groups in the Kediri community are divided into three based on their position in the royal government.
1. The central social group (kingdom), namely the people who are in the environment of the king and some of his relatives and the group of servants.
2. Thani (regional) community, namely community groups consisting of officials or government officials in the Thani (regional) area.
3. Non-governmental community groups, namely groups of people who do not have official positions and relations with the government or the self-employed community. Kediri has more than 300 officials in charge of managing and recording all royal income. In addition, there were 1,000 petty officials in charge of the city's forts and moats, the royal treasury, and the food supply building.

The Kingdom of Kediri was born from the division of the Mataram Kingdom by King Airlangga (1000-1049). This solution was done so that there would be no disputes between the concubine's children. There is no clear evidence of how the kingdom was divided into several parts. In the babad it is stated that the kingdom was divided into four or five parts. But in its development, only two kingdoms were often mentioned, namely Kediri (Pangjalu) and Jenggala. Samarawijaya as the legal heir to the kingdom received the old capital, namely Dahanaputra, and the name of the kingdom was changed to Pangjalu or also known as the Kingdom of Kediri.

Economic Conditions in the Age of the Kingdom of Kediri
Kediri's economy is based on trade, animal husbandry, and agriculture. Kediri is known as a producer of rice, cotton, and silkworms. Thus, from an economic perspective, the kingdom of Kediri was quite prosperous. This can be seen from the kingdom's ability to provide a steady income to its employees who are paid with crops. This information was obtained based on the book Chi-Fan-Chi and the book Ling-wai-Tai-ta.

Literary Works and Inscriptions in the Age of the Kingdom of Kediri
Inscriptions at the Age of the Kingdom of Kediri include:
a. The Banjaran inscription dating to 1052 AD describes the victory of Panjalu or Kediri over Jenggala
b. The Hantang inscription in 1135 or 1052 AD describes Panjalu or Kediri during the time of King Jayabaya. This inscription contains the motto Panjalu Jayati which means Kediri Wins. This inscription was issued as a certificate of endowment ratification for residents of Ngantang Village who were loyal to Kediri during the war with Jenggala. And from the inscription, it can be seen that King Jayabhaya was the king who succeeded in defeating Janggala and reuniting him with Kediri.
c. Japanese inscription 1144 AD
d. Talan Inscription 1136 AD Literary art also received a lot of attention during the Kadiri Kingdom era. In 1157 Kakawin Bharatayuddha was written by Mpu Sedah and completed by Mpu Panuluh. This book comes from the Mahabharata which contains the victory of the Pandavas over the Korawas, as an allegory, victory.

Literary art received a lot of attention during the Panjalu Kingdom of Kediri. In 1157 Kakawin Bharatayuddha was written by Mpu Sedah and completed by Mpu Panuluh. This book comes from the Mahabharata which contains the victory of the Pandavas over the Korawas, as an allegory of Sri Jayabhaya's victory over Janggala.

Apart from that, Mpu Panuluh also wrote Kakawin Hariwangsa and Ghatotkachasraya. There is also a poet during the reign of Sri Kameswara named Mpu Dharmaja who wrote Kakawin Smaradahana. Then during the reign of Kertajaya, there was a poet named Mpu Monaguna who wrote Sumanasantaka and Mpu Triguna who wrote Kresnayana.

In addition to the literary books and inscriptions mentioned above, Chinese news was also found which gave many descriptions of the life of the people and government of Kediri which could not be found in other sources. The Chinese news was compiled through a book entitled Ling-mai-tai-ta written by Cho-Ku-Fei in 1178 AD and the Chu-Fan-Chi book written by Chau-Ju-Kua in 1225 AD. Thus inscriptions, Literary books, and books written by Chinese people are the development of Kediri.

The collapse of Kediri
The collapse of the Kediri kingdom was due to the fact that during the reign of Kertajaya, there was a conflict with the Brahmins. They considered Kertajaya to have violated religion and forced him to worship him as a god. Then the Brahmins asked for protection from Ken Arok, Akuwu Tumapel. The feud culminated into a battle in the village of Ganter, in 1222 AD. In that battle Ken Arok was able to defeat Kertajaya, at that time marking the end of the Kediri kingdom.

After successfully defeating Kertanegara, the Kingdom of Kediri rose again under the reign of Jayakatwang. One of the Singasari troop leaders, Raden Wijaya, managed to escape to Madura. Because of his good behavior, Jayakatwang allowed Raden Wijaya to open the Tarik Forest as his residence. In 1293, came the Mongol army sent by Emperor Kublai Khan to take revenge against Kertanegara. This situation was used by Raden Wijaya to attack Jayakatwang. He cooperated with the Mongol army and Madurese troops under the leadership of Arya Wiraraja to attack Kediri. In that war, Jayakatwang's troops were easily defeated. After that there was no more news about the Kingdom of Kediri.

History of Mathematics

The branch of study known as the history of mathematics is the investigation of the origins of discoveries in mathematics and, to a lesser extent, the investigation of the methods and notation of mathematics in the past.

Prior to modern times and the worldwide spread of knowledge, written examples of the development of mathematics had glittered in only a few places. The oldest mathematical writings that have been found are Plimpton 322 (Babylonian mathematics c. 1900 BC), the Rhind Mathematical Tablets (Egyptian mathematics c. 2000-1800 BC), and the Moscow Mathematical Gazette (Egyptian mathematics c. 1890 BC). All of these workers deal with a theorem commonly known as the Pythagorean theorem, which seems to be the oldest and most widespread mathematical development after basic arithmetic and geometry.

The contributions of Greek mathematicians refined the methods (especially through the introduction of deductive reasoning and mathematical rigor in mathematical proofs) and expanded the subject of mathematics. The word "mathematics" itself is derived from the ancient Greek word, μάθημα (mathematics), which means "subject". Chinese mathematics made early contributions, including positional notation. The Hindu-Arabic number system and the rules for using its operations, used today, were probably developed through lectures in the first millennium AD in Indian mathematics and have been passed on to the West through Islamic mathematics. Islamic mathematics, in turn, developed and extended mathematical knowledge to this civilization. Many Greek and Arabic texts on mathematics were later translated into Latin, leading to the further development of mathematics in the European Middle Ages.

From ancient times through the Middle Ages, bursts of mathematical creativity were often followed by centuries of stagnation. Beginning in Renaissance Italy in the 16th century, new mathematical developments, interacting with new scientific discoveries, were made at an exponential growth rate that continues today.

Prehistoric mathematics
The origins of mathematical thinking lie in the concepts of numbers, quantities, and shapes. Modern studies of animal fossils show that this concept is not unique to humans. This concept may also be an everyday part of the hunter pack. That the concept of numbers developed step by step over time is evidence that in some languages ​​today the distinction between "one", "two" and "many" is preserved, but that numbers greater than two are not.

The oldest known mathematical object is the Lebombo bone, found in the Lebombo mountains in Swaziland and probably dates to 35000 BC. This bone contains 29 different incisions that are deliberately etched into the baboon's fibula. There is evidence that women used to do the math to memorize their menstrual cycles; 28 to 30 scratches on bone or stone, followed by distinct markings. Also, prehistoric artifacts found in Africa and France, from 35,000 BC and 20,000 years old, suggest early attempts to calculate time.

The Ishango bone, found near the watercourse of the Nile (northeast Congo), contains a row of stick marks etched in three longitudinal stripes on the bone. The common interpretation is that the Ishango bones show the oldest known demonstration of the sequence of prime numbers or the six-month lunar calendar. Predynastic period Egypt from the 5th millennium BC, graphically featuring geometric designs. It has been claimed that megalithic structures in England and Scotland, from the 3rd millennium BC, incorporated geometrical ideas such as the circle, ellipse, and Pythagorean triples in their design.

History of Radio

History of Radio
The history of radio is the history of technology that produces radio equipment that uses radio waves. Initially, signals on radio broadcasts were transmitted via continuous data waves either through amplitude modulation (AM) or frequency modulation (FM). This method of sending signals is called analog. Furthermore, along with the development of technology, the internet was discovered, and digital signals which then changed the way radio signals are transmitted

History of Radio Use
Many of radio's early uses were maritime, for sending telegraphic messages using Morse code between ships and land. One of its early uses included the Japanese Navy spying on the Russian fleet during the Battle of Tsushima in 1901. One of its most memorable uses was during the sinking of the RMS Titanic in 1912, including communication between operators on board the sunken ship and nearby ships and communications to ground station. Radio was used to pass on orders and communications between the Army and Navy on both sides in World War II; Germany used radio communications for diplomatic messages when its submarine cables were cut by the British. The United States relayed President Woodrow Wilson's 14 Point Program to Germany by radio during the war. Broadcasting began in the 1920s, with the popularity of radio sets, especially in Europe and the United States.

In addition to broadcasting, point-to-point broadcasting, including telephone and rebroadcasting of radio programs, became popular in the 1920s and 1930s. The pre-war use of radio was to improve the detection and location of aircraft and ships with the use of radar. Today, radio takes many forms, including wireless networks, mobile communications of all types, as well as radio broadcasting. Before television became popular, commercial radio broadcasts included drama, comedy, various shows, and many other forms of entertainment; not only news and music.

Radio AM
AM radio (amplitude modulation) works on the principle of modulating radio waves and audio waves. Both of these waves have a constant amplitude. However, this modulation process then changes the amplitude of the conducting (radio) wave according to the amplitude of the audio wave.

In 1896 the Italian scientist, Guglielmo Marconi received a patent for a wireless telegraph using two circuits. At that time this signal could only be sent over short distances. However, this is what started the development of radio technology. In 1897 Marconi again published his discovery that wireless signals could be transmitted over longer distances (12 miles). Furthermore, in 1899 Marconi succeeded in making wireless communication between France and England via the English Channel using the Tesla oscillator.

John Ambrose Fleming in 1904 discovered that audio tubes could be used as wireless receivers for this radio technology. Two years later Dr. Lee deForest invented the electron tube consisting of three elements (triode audion). This invention made it possible for sound waves to be transmitted via wireless communication systems. But the captured signal is still very weak. It was only in 1912 [[Edwin Howard Armstrong discovered a radio wave amplifier also called a radio amplifier. This tool works by capturing electromagnetic signals from radio transmissions and providing a return signal from the tube. That way the signal strength will increase as much as 20,000 times per second. The captured sound is also much stronger so that it can be heard directly without using earphones. This discovery then becomes very important in radio communication systems because it is much more efficient than previous tools. Nevertheless, the patent on the amplifier fell into the hands of Dr. Lee de forest. Until now, radio amplifier is still the core technology in radio equipment.

Initially, the use of AM radio was only for wireless telegram purposes. The first person to broadcast radio with a human voice was Reginald Aubrey Fessenden. He made the first radio broadcast with a human voice on December 23, 1900, at a distance of 50 miles (from Cobb Island to Arlington, Virginia). Today AM radio is not used too much for commercial radio broadcasts because of the poor sound quality.

Radio FM
FM radio (frequency modulation) works on a principle similar to AM radio, namely by modulating radio waves (conductor) with audio waves. It's just that, on FM radio this modulation process causes a change in frequency.

When AM radio became common, Armstrong discovered that another problem with radio lay in the type of signal being transmitted. At that time audio waves were transmitted along with radio waves using amplitude modulation (AM). This modulation is very vulnerable to weather disturbances. In the late 1920s, Armstrong began trying to use modulation where the amplitude of the conducting (radio) wave was kept constant. In 1933 he finally found a frequency modulation (FM) system that produced a much clearer sound and was not disturbed by bad weather.

Unfortunately, this technology is not necessarily used en masse. The economic depression of the 1930s made the radio industry reluctant to adopt this new system because it required the costly replacement of transmitters and receivers. It wasn't until 1940 that Armstrong was able to set up the first FM radio station at his own expense. Two years later the Federal Communications Commission (FCC) allocated some frequencies to the FM radio station that Armstrong had built. It took a long time for frequency modulation to become a widely used system. In addition, Armstrong never obtained a patent.

Frustrated by all the difficulties in fighting for the FM system, Armstrong ended his life tragically by committing suicide. Luckily his wife then managed to fight for Armstrong's rights to his invention. It was only in the late 1960s that FM became a truly established system. With nearly 2000 FM radio stations spread across America, FM became a supporter of microwaves (microwave), in the end, FM was truly recognized as a superior system in various fields of communication.

Internet radio
The invention of the internet started to change the analog signal transmission used by the conventional radio. Internet radio (also known as web radio, streaming radio, and e-radio) works by transmitting sound waves over the internet. The working principle is almost the same as conventional short-wave radio, namely by using a streaming medium in the form of a continuous wave. This working system allows radio broadcasts to be heard throughout the world as long as the listener has an internet device. That is why many expatriates use internet radio to relieve their homesickness. In Indonesia, generally, internet radio collaborated with an analog radio system by terrestrial radio stations to expand their broadcast reach.

Satellite Radio
Satellite radio transmits audio waves using digital signals. Unlike analog signals that use continuous waves, sound waves are transmitted via digital signals consisting of binary 0 and 1 codes. This signal is transmitted to a much wider coverage area because it uses satellites. It's just that radio broadcasts can only be received by special devices that can decode encrypted signals. Satellite radio broadcasts can also only be received in open areas where the antenna on the radio is in line of sight with the transmitting satellite. Satellite radio will only work where there are no major obstructions such as tunnels or buildings. Therefore satellite radio devices are widely promoted for car radios. To get good broadcast transmission, it is necessary to make repeater stations like in America so that the service quality is excellent.

Expensive equipment (because it uses satellites) makes this system commercial. Listeners must subscribe to be able to listen to radio broadcasts. Even so, the sound quality produced is very clear, there is no noise like in conventional radio broadcasts. In addition, most of the broadcast content is ad-free and listeners have a much wider choice of broadcast channels (more than 120 channels).
The world's satellite radio provider company is Worldspace which serves satellite radio broadcasts in America, Europe, Asia, Australia, and Africa. Worldspace has three satellites serving different regions. In Indonesia, until 2002 Worldspace collaborated with RRI, Trijaya Radio, Borneo Wave Channel (Masima Group), goindo.com, and Kompas Cyber ​​Media as content fillers for satellite radio services using the Asia Star satellite. mbs fm Suci manyar Gresik

High-definition radio (HD Radio)
Radio, also known as digital radio, works by combining analog and digital systems as well. This allows two digital and analog stations to share the same frequency. This efficiency allows multiple contents to be broadcast in the same position. The sound quality produced by HD radio is as clear as satellite radio, but the service is offered free of charge. However, to be able to receive digital radio broadcasts, listeners must have a special device that can capture digital signals.

History of Radio of the Republic of Indonesia (RRI History)

Sejarah Radio Republik Indonesia
The history of Radio Republik Indonesia (RRI) began with its official establishment on September 11, 1945, by figures who previously actively operated several Japanese radio stations in 6 cities. Meeting of delegates from 6 radio stations at Adang Kadarusman's house, Jalan Menteng Dalam, Jakarta. So that resulted in the decision to establish Radio Republik Indonesia by choosing dr. Abdulrahman Saleh as the first general leader of RRI.

The beginning
The first radio broadcast in Indonesia (at that time it was called Nederlands Indie - Dutch East Indies), was Bataviase Radio Vereniging (BRV) in Batavia (formerly Jakarta Tempo), which was officially established on June 16, 1925, so five years after in the United States, three years after in England and the Soviet Union.

Radio stations in Indonesia during the Dutch colonial era used to have private status. Because since the existence of the BRV earlier, other radio broadcasting bodies have emerged: Nederlandsch Indische Radio Omroep Masstchapyj (NIROM) in Jakarta, Bandung and Medan, Solossche Radio Vereniging (SRV) in Solo, Mataramse Vereniging Voor Radio Omroep (MAVRO) in Yogjakarta, Vereniging Oosterse Radio Luisteraars (VORO) in Bandung, Vereniging Voor Oosterse Radio Omroep (VORO) in Surakarta, Chinese en Inheemse Radio Luisteraars Vereniging Oost Java (CIRVO) in Surabaya, Eerste Madiunse Radio Omroep (EMRO) in Madiun and Radio Semarang in Semarang.

In Medan, apart from NIROM, there is also the private Meyers Omroep Voor Allen (MOVA) radio, operated by Mr. Meyers, and Algemene Vereniging Radio Omroep Medan (AVROM). Among the many broadcast radio agencies, NIROM is the largest and most comprehensive, because it received full support from the Dutch East Indies government.

NIROM's rapid development was also due to its large financial benefits, namely from the "radio tax". The more radios among the people, the more money NIROM receives. Thus, NIROM can increase its transmit power, set up relay stations, establish special telephone lines with big cities, etc.

At that time there were special telephone lines between Batavia, Bogor, Sukabumi, Bandung, Cirebon, Tegal, Pekalongan, Semarang, Solo, Yogyakarta, Magelang, Surabaya, Tangerang, Depok, Bekasi, Malang, which totaled approximately 1.2 million meters of telephone lines. phone to modulate the transmitters in those cities. Thus NIROM can hold central broadcasts from Semarang, Bandung, Surabaya, Yogyakarta, or Solo.

This is very different from other radio broadcasting bodies which are in the form of private associations, especially those operated by indigenous peoples, who live off members' contributions.

The emergence of associations of radio stations among the Indonesian people was due to the fact that NIROM did receive assistance from the Dutch East Indies government; it was more of a company seeking financial gain and helping the establishment of colonialism in the Dutch East Indies. At that time the Dutch colonial government was facing a national spirit among the native population which had flared up since 1908, especially after 1928.

Solosche Radio Vereniging (SRV), which was established on April 1, 1933, was the pioneer for the emergence of business broadcast radio for the Indonesian nation.

Since 1933, the establishment of other radio broadcasting agencies, the efforts of the Indonesian nation in various big cities as mentioned above, and the establishment of SRV, MARVO, VORL, CIRVO, EMRO, and Radio Semarang were initially assisted by NIROM, because NIROM received material broadcasts that are eastern in nature from the various associations earlier. But then it turned out that NIROM was worried that the eastern radio associations were dangerous for him.

In 1936 news emerged that starting in 1937 "Eastern Broadcasting would be entirely controlled by NIROM itself". This meant that starting in 1937 the subsidy from NIROM would be removed, at least reduced, because NIROM would no longer relay native-owned radio broadcasts, at least if they were forced to relay very little. As is known, the NIROM subsidy was originally given based on relay-hour calculations.

The news caused quite a stir among radio people outside NIROM because the removal of the subsidy would weaken the radio broadcasting bodies in question. Indeed, it was NIROM's intention, which relied on the colonial power, to kill eastern radio broadcasting associations.

On March 29, 1937, thanks to the efforts of members of the Volksraad M.Sutarjo Kartokusumo and an engineer named Ir. Sarsito Mangunkusumo, a meeting was held between eastern radio representatives located in Bandung. The representatives who sent their delegates were: VORO (Jakarta), VORL (Bandung), MAVRO (Yogyakarta), SRV (Solo), and CIRCO (Surabaya), the meeting that day gave birth to a new body called: THE EAST EAST RADIO ASSOCIATION (PPRK) as its chairman: Sutarjo Kartohadikusumo.

PPRK's non-commercial aim is "Social-cultural" solely to promote national art and culture for the advancement of Indonesian society, spiritually and physically.

On May 7, 1937, because of PPRK's efforts, a meeting was held with government officials to discuss the relationship between PPRK and NIROM. The meeting resulted in a mutual agreement that PPRK would organize eastern broadcasts, and NIROM would organize the technical aspects.

Since then PPRK has been trying hard so that PPRK can carry out it completely on its own without the help of NIROM.

As is known, on September 1, 1939, Germany under the leadership of Adolf Hitler invaded Poland which caused World War II, and then in 1940, Germany occupied Denmark, Norway, Belgium, and the Netherlands.

On November 1, 1940, the goal of PPRK was achieved, namely to hold the first broadcast from PPRK.

Get to know the figure of General Soedirman

Get to know the figure of Soedirman, the War General highly respected by President Soekarno

Indonesia has one of the best war generals in history. He was General Soedirman, whom even President Soekarno respected very much. He was even used as his right hand in fighting to save this country from the Dutch who wanted to return to colonize, assisted by allied soldiers. General Soedirman fought tooth and nail to make Indonesia continue to be independent and recognized by the international community.

Let's take a moment to get to know and remember this meritorious figure in Indonesia. Without him, Indonesia will fall and return to the lap of the Netherlands. Even though they became independent in 1945, the Dutch still "insisted" on wanting to control Indonesia. And this is the story of the life and struggle of the famous General Soedirman.

General Soedirman and Soeharto

Smart Youth Who Live Away from Parents
Since birth, General Soedirman did not live with his parents. He lived with his mother's brother, Raden Cokrosunaryo, who was a district head at the time. General Soedirman also received the title Raden because Cokrosunaryo considered him his own son. Since childhood, he was educated very well by his adoptive parents. He was sent to school to become a very intelligent young man.
General Soedirman and Soeharto

From childhood until he was 18 years old, General Soedirman was never told who his real parents were. He only knew that Cokrosunaryo was a father who loved him sincerely. After knowing this fact, General Soedirman was finally allowed to live again with his family even though in the end he was more active in studying after his real father died.


A Devout with High Nationalism.
Since childhood, General Soedirman was often taught about obedience to religion. Inevitably he always prays on time. In fact, he is often nicknamed "Haji" by his friends who attend Indigenous schools (Hollandsch Inlandsche School). This obedience continues to increase along with new knowledge and also guidance from his teachers.

President Soekarno and General Soedirman

During school, General Soedirman was taught a lot about what nationalism meant. From here, a very high sense of nationalism was nurtured. He is a young man who wants to fight for this country. In fact, he is willing to do what he can to make a big enough change.

Become a Strong Master and Spread the Fighting Spirit
In his eighth year of school, General Soedirman finally continued his education at Wirotomo. It was at this school that his views on colonialism rose sharply. General Soedirman learned a lot of new things ranging from science, and mathematics, to Indonesian and Dutch which were spoken very fluently. When he was 19 years old he started teaching at Wirotomo although, in the end, he had to continue his studies at Kweekschool.
Unfortunately, the lecture period from General Soedirman had to end after a year. He has no more money to pay tuition fees which is quite suffocating. Finally, with a heavy heart, General Soedirman returned to Cilacap and taught at the Muhammadiyah elementary school which made him increasingly known and recognized by many people.

The intelligence possessed by General Soedirman made a girl named Alfiah smitten. Finally, General Soedirman married Alfiah who was the son of the richest batik entrepreneur in the area. From this marriage, General Soedirman was blessed with 3 children named Didi Praptoastusi, Didi Sutjiati, and Titi Wahjuti Setyaningrum.

Become a Member of PETA Formed by Japan
General Soedirman was once a member of PETA which was an army formed by Japan. He was appointed commander and tasked with recruiting many young people in his area to join PETA. The Japanese trained Soedirman along with other native children to fight in the hope of being able to fight and dispel the Allied troops who had begun to intensively hunt down the Japanese wherever they were.
The upheaval of PETA troops in other areas made General Soedirman's subordinates join in the rebellion. They even killed one Japanese. Knowing this, General Soedirman made sure that his men were not killed as a condition for ending the rebellion. The Japanese agreed to this even though they eventually sent them to concentration camps and were put to work roughly.

Began to be trusted as a war leader
After being exiled to a concentration camp, General Soedirman and his men fled to Jakarta. They knew that Hiroshima and Nagasaki were bombed and that Indonesia's independence could be obtained right away. He met Soekarno and was told to describe himself as a member of the Banyumas branch of the People's Security Agency. From here the struggle of General Soedirman continued. Even making him the most trusted person in Indonesia by Soekarno.
General Soedirman's military career went up drastically. In fact, he was aligned with military officials who were more senior than him. General Soedirman's endless tenacity and struggle made him shine even more. Even the title of General was embedded in his name as the highest award this country could give him.

The Great Guerrilla War
One of the most famous of General Soedirman's is the guerrilla war that he did. He traveled hundreds of kilometers to develop the best war strategy for the Netherlands and the allies. The war strategies devised by General Soedirman ultimately benefited Indonesia.

The guerrilla war carried out by General Soedirman made the Dutch numb. They don't know that Indonesia is capable of making such a great strategy. What was done by General Soedirman was welcomed by many people in Indonesia. Without this war, the fate of Indonesia may still be hanging in the balance.

The general who died young for his people
During the guerrilla attack, General Soedirman was already seriously ill. He had tuberculosis which damaged his lungs. Knowing this, he continues to fight for the sake of making this country recognized by the world. His struggles finally paid off. On December 27, 1949, the Netherlands officially recognized Indonesian sovereignty.
Death of General Soedirman

A month later after Indonesia was officially recognized as sovereign. This great general finally died. The severe illness that befell him apparently took his life quickly. He has not even had the chance to enjoy the country he has defended so hard that he is finally recognized by the international community.

This is a bit of the life story of the great General Soedirman. Even though he finally died at a young age, he brought big changes to Indonesia. And we all have to pay the greatest respect to him by loving this Indonesian nation from the shackles of the colonialists and national traitors.

Inventor of the Chicken Claw Foundation

Prof. Ir. R.M. Sedyatmo. He was born in Karanganyar, Central Java in 1909 he was an Indonesian engineer. Ir. Sedyatmo is often nicknamed "The Kancil" because he is famous for his many ingenuity studies at the Technische Hogeschool (THS) (now ITB) Bandung.

After leaving THS in 1934, Sedyatmo worked as a planning engineer for various government agencies. Sedyatmo is known as the inventor of the "Chicken Claw Foundation" in 1962. Sedyatmo's invention was initially used in the construction of the Juanda Naval Airport Apron, Surabaya, Polonia Airport Runway, Medan, and Soekarno-Hatta Airport Runway, Jakarta. The results of these findings have been patented and used abroad.

The chicken claw foundation consists of a reinforced concrete slab with a thickness of 10-15 cm, depending on the type of construction and the condition of the soil beneath it. Under the concrete slab, pipe pits are made with an axis spacing of 2-3 m. The diameter of the pipe is 1.20 m, the thickness is 8 cm, and the length depends on the load on the plate and the soil conditions. Single reinforcement is used for pipes, while double reinforcement is used for plates.

The chicken claw foundation system is very simple, so it is very suitable to be applied in areas where modern equipment and skilled workers are hard to come by. To some extent, this system can replace pile foundations. For a 3-4 story building, for example, the chicken claw system will cost the same as a 12-meter pile foundation.
Chicken Claw Foundation

However, Sedyatmo was not a scientist who was hungry for awards. His humble attitude and high dedication to the nation are the spirits of his creations. And uniquely, Sedyatmo always emphasizes the importance of intuition and observation of the universe. His chicken claw work is a testament to how his creations were inspired by the roots of the coconut tree.

Some of Sedyatmo's other well-known works are the hydraulic pump, the Jatiluhur dam, and even the Suramadu bridge built based on Sedyatmo's initial concept. Not surprisingly, his extraordinary contribution to engineering knowledge won Sedyatmo a number of international awards.

Name Ir. Sedyatmo was later immortalized as the name of the freeway (Toll Road) from Jakarta to Soekarno-Hatta airport. Professor Sedyatmo died at the age of 75 in 1984 and was buried in Karanganyar. The Indonesian government awarded Sedyatmo the Class I Mahaputra Star for his services.

Biografi Ismail Marzuki Sang Mestro Musik

Ismail Marzuki
Ismail Marzuki termasuk pahlawan nasional yang dikenal sebagai salah satu sang maestro musik Indonesia. Dari tangannya, banyak tercipta karya-karya lagu perjuangan yang sampai sekarang terus dinyanyikan oleh rakyat Indonesia. Besarnya jasa Ismail Marzuki membuat pemerintah Indonesia menganugerahkan gelar Pahlawan Nasional kepada Ismail Marzuki.
Nama : Ismail Marzuki
Lahir : Jakarta, 11 Mei 1914
Wafat : Jakarta, 25 Mei 1958
Orang Tua : Marzuki (ayah), Solechah (ibu)
Istri : Eulis Zuraidah
Anak : Rachmi Aziah
Gelar : Pahlawan Nasional

Ismail Marzuki lahir di Kwitang, Senen, Batavia, 11 Mei 1914. Ismail Marzuki yang lebih dikenal dengan panggilan Maing. Ia merupakan anak dari keluarga keturunan Betawi. Ismail Marzuki dikenal memiliki bakat seni yang sulit dicari bandingannya. Sosoknya pun mengagumkan. Ia merupakan anak dari pasangan Marzuki dan Solechah.

Dalam biografi Ismail Marzuki, ia terkenal sebagai pemuda yang berkepribadian luhur dan tergolong anak pintar. Ismail sejak muda senang tampil necis. Bajunya disetrika licin, sepatunya mengkilat dan ia senang berdasi. Darah seni Ismail mengalir dari ayahnya, Marzuki, yang saat itu seorang pegawai di perusahaan Ford Reparatieer TIO.

Ayahnya, Marzuki dikenal gemar memainkan kecapi dan piawai melagukan syair-syair yang bernafaskan Islam. Jadi tidak aneh kalau kemudian Ismail sejak kecil sudah tertarik dengan lagu-lagu.
Orang tua Ismail Marzuki yakni Marzuki dan Solechah termasuk golongan masyarakat Betawi intelek yang berpikiran maju. Ismail Marzuki yang dipanggil dengan nama Ma’ing, sejak bocah sudah menunjukkan minat yang besar terhadap seni musik.

PENDIDIKAN ISMAIL MARZUKI
Ayahnya berpenghasilan cukup sehingga sanggup membeli piringan hitam dan gramafon yang populer disebut “mesin ngomong” oleh masyarakat Betawi tempo dulu. Ismail Marzuki di sekolahkan ayahnya ke sebuah sekolah Kristen HIS Idenburg, Menteng.

Nama panggilannya di sekolah adalah Benyamin. Tapi kemudian ayahnya merasa khawatir kalau nantinya bersifat kebelanda-belandaan, Ismail Marzuki lalu dipindahkan ke Madrasah Unwanul-Falah di Kwitang. Beranjak dewasa, dia dibelikan ayahnya alat musik sederhana.

Bahkan tiap naik kelas Ismail Marzuki diberi hadiah harmonika, mandolin, dan gitar. Setelah lulus, ia masuk sekolah MULO dan membentuk grup musik sendiri. Di situ dia memainkan alat musik banyo dan gemar memainkan lagu-lagu gaya Dixieland serta lagu-lagu Barat yang digandrungi pada masa itu.

Setelah tamat MULO, Ismail Marzuki bekerja di Socony Service Station sebagai kasir dengan gaji 30 gulden sebulan, sehingga dia sanggup menabung untuk membeli biola. Namun, pekerjaan sebagai kasir dirasakan kurang cocok baginya.

Ia kemudian pindah pekerjaan dengan gaji tidak tetap sebagai verkoper (penjual) piringan hitam produksi Columbia dan Polydor yang berkantor di Jalan Noordwijk (sekarang Jalan Ir. H. Juanda) Jakarta.

Terjun Ke Dunia Musik
Penghasilannya tergantung pada jumlah piringan hitam yang dia jual. Rupanya, pekerjaan ini hanya sebagai batu loncatan ke jenjang karier berikutnya dalam bidang musik.
Selama bekerja sebagai penjual piringan hitam, Ismail Marzuki banyak berkenalan dengan artis pentas, film, musik dan penyanyi, di antaranya Zahirdin, Yahya, Kartolo, dan Roekiah (orangtua Rachmat Kartolo). Pada 1936, Ismail Marzuki memasuki perkumpulan orkes musik Lief Jawa sebagai pemain gitar, saksofon, dan harmonium pompa.

Menciptakan Lagu Sendiri
Tahun 1934, Belanda membentuk Nederlands Indische Radio Omroep Maatshappij (NIROM) dan orkes musik Lief Java mendapat kesempatan untuk mengisi acara siaran musik. Tapi Ismail Marzuki mulai menjauhkan diri dari lagu-lagu Barat, kemudian menciptakan lagu-lagu sendiri antara lain “Ali Baba Rumba”, “Ohle le di Kotaraja”, dan “Ya Aini”.

Lagu ciptaannya kemudian direkam kedalam piringan hitam di Singapura. Orkes musiknya punya sebuah lagu pembukaan yang mereka namakan Sweet Jaya Islander.

Lagu tersebut tanpa pemberitahuan maupun basa-basi dijadikan lagu pembukaan siaran radio NIROM, sehingga grup musik Ismail Marzuki mengajukan protes, namun protes mereka tidak digubris oleh direktur NIROM.

Pada periode 1936-1937, Ismail Marzuki mulai mempelajari berbagai jenis lagu tradisional dan lagu Barat. Ini terlibat pada beberapa ciptaannya dalam periode tersebut, “My Hula-hula Girl”. Kemudian lagu ciptaannya “Bunga Mawar dari Mayangan” dan “Duduk Termenung” dijadikan tema lagu untuk film “Terang Bulan”.

Awal Perang Dunia II (1940) mulai mempengaruhi kehidupan di Hindia-Belanda (Indonesia). Radio NIROM mulai membatasi acara siaran musiknya, sehingga beberapa orang Indonesia di Betawi mulai membuat radio sendiri dengan nama Vereneging Oostersche Radio Omroep (VORO) berlokasi di Kramat Raya. Antena pemancar mereka buat sendiri dari batang bambu.

Tiap malam Minggu orkes Lief Java mengadakan siaran khusus dengan penyanyi antara lain Annie Landouw. Ismail Marzuki malah jadi pemain musik sekaligus mengisi acara lawak dengan nama samaran “Paman Lengser” dibantu oleh “Botol Kosong” alias Memet.

Karena Ismail Marzuki sangat gemar memainkan berbagai jenis alat musik, suatu waktu dia diberi hadiah sebuah saksofon oleh kawannya yang ternyata menderita penyakit paru-paru. Setelah dokter menjelaskan pada Ismail Marzuki, lalu alat tiup tersebut dimusnahkan. Tapi, mulai saat itu pula penyakit paru-paru mengganggunya.

Membentuk Perikatan Radio Ketimuran (PRK)
Ketika Ismail Marzuki membentuk organisasi Perikatan Radio Ketimuran (PRK), pihak Belanda memintanya untuk memimpin orkes studio ketimuran yang berlokasi di Bandung (Tegal-Lega). Orkesnya membawakan lagu-lagu Barat.

Pada periode ini dia banyak mempelajari bentuk-bentuk lagu Barat, yang digubahnya dan kemudian diterjemahkannya ke dalam nada-nada Indonesia.

Sebuah lagu Rusia ciptaan R. Karsov diterjemahkan ke dalam bahasa Sunda menjadi “Panon Hideung”. Sebuah lagu ciptaannya berbahasa Belanda tapi memiliki intonasi Timur yakni lagu “Als de orchideen bloeien”. Lagu ini kemudian direkam oleh perusahaan piringan hitam His Master Voice (HMV). Kelak lagu ini diterjemahkan lagi ke dalam bahasa Indonesia dengan judul “Bila Anggrek Mulai Berbunga”.

Tahun 1940, Ismail Marzuki menikah dengan penyanyi kroncong Eulis Zuraidah. Pada Maret 1942, saat Jepang menduduki seluruh Indonesia, Radio NIROM dibubarkan diganti dengan nama Hoso Kanri Kyoku. PRK juga dibubarkan Jepang, dan orkes Lief Java berganti nama Kireina Jawa.

Menciptakan Lagu Perjuangan
Saat itu Ismail Marzuki mulai memasuki periode menciptakan lagu-lagu perjuangan. Mula-mula syair lagunya masih berbentuk puitis yang lembut seperti “Kalau Melati Mekar Setangkai”, “Kembang Rampai dari Bali” dan bentuk hiburan ringan, bahkan agak mengarah pada bentuk seriosa.

Dalam Biografi Ismail Marzuki diketahui bahwa pada periode 1943-1944, Ismail Marzuki menciptakan lagu yang mulai mengarah pada lagu-lagu perjuangan, antara lain “Rayuan Pulau Kelapa”, “Bisikan Tanah Air”, “Gagah Perwira”, dan “Indonesia Tanah Pusaka”.

Kepala bagian propaganda Jepang, Sumitsu, mencurigai lagu-lagu tersebut lalu melaporkannya ke pihak Kenpetai (Polisi Militer Jepang), sehingga Ismail Marzuki sempat diancam oleh Kenpetai. Namun, putra Betawi ini tak gentar. Perjuangan Ismail Marzuki selanjutnya pada 1945 menciptakan lagu “Selamat Jalan Pahlawan Muda”.

Setelah Perang Dunia II, ciptaan lagu Ismail Marzuki terus mengalir, antara lain “Jauh di Mata di Hati Jangan” (1947) dan “Halo-halo Bandung” (1948). Ketika itu Ismail Marzuki dan istrinya pindah ke Bandung karena rumah mereka di Jakarta kena dihantam peluru mortir.

Ketika berada di Bandung selatan, ayah Ismail Marzuki di Jakarta meninggal. Ismail Marzuki terlambat menerima berita. Ketika dia tiba di Jakarta, ayahnya telah beberapa hari dimakamkan. Kembang-kembang yang menghiasi makam ayahnya dan telah layu, mengilhaminya untuk menciptakan lagu “Gugur Bunga”.

Lagu-lagu ciptaan lainnya mengenai masa perjuangan yang bergaya romantis tanpa mengurangi nilai-nilai semangat perjuangan antara lain “Ke Medan Jaya”, “Sepasang Mata Bola”, “Selendang Sutra”, “Melati di Tapal Batas Bekasi”, “Saputangan dari Bandung Selatan”, “Selamat Datang Pahlawan Muda”.

Lagu hiburan populer yang (kental) bernafaskan cinta pun sampai-sampai diberi suasana kisah perjuangan kemerdekaan. Misalnya syair lagu “Tinggi Gunung Seribu Janji”, dan “Juwita Malam”.

Lagu-lagu yang khusus mengisahkan kehidupan para pejuang kemerekaan, syairnya dibuat ringan dalam bentuk populer, tidak menggunakan bahasa Indonesia tinggi yang sulit dicerna. Simak saja syair “Oh Kopral Jono” dan “Sersan Mayorku”.

Lagu-lagu ciptaannya yang berbentuk romantis murni hiburan ringan, walaupun digarap secara populer tapi bentuk syairnya berbobot seriosa. Misalnya lagu “Aryati”, “Oh Angin Sampaikan". Tahun 1950 dia masih mencipta lagu “Irian Samba” dan tahun 1957 lagu “Inikah Bahagia” suatu lagu yang banyak memancing tanda tanya dari para pengamat musik.

Sampai pada lagu ciptaan yang ke 100-an, Ismail Marzuki masih merasa belum puas dan belum bahagia. Malah, lagu ciptaannya yang ke-103 tidak sempat diberi judul dan syair.

Ismail Marzuki Wafat
Hingga Ma’ing alias Ismail Marzuki komponis besar Indonesia itu menutup mata selamanya pada 25 Mei 1958. Peran Ismail Marzuki terhadap sejarah musik Indonesia sangat vital, khususnya lagu-lagu perjuangan yang ia ciptakan.

Commodore Yos Sudarso Biography

Vice Admiral TNI (Ant) Yosaphat Soedarso
Yos Sudarso's name is known by the Indonesian people as a national hero, and his name has been immortalized as the name of a street in Indonesian territory and also an island in Papua. He died in the Aru Sea, on January 15, 1962, at the age of 36 aboard the KRI Macan Tutul on a mission to liberate West Irian (Papua) through the battle of the Aru Sea after his ship KRI Macan Tutul was shot by the patrol boat Hr. Ms. Eversten belonged to the Dutch fleet during the Trikora campaign.

In many books that review the biography and profile of Vice Admiral TNI (Ant) Yosaphat Soedarso, better known as Yos Sudarso, he is said to have been born in the Salatiga region, Central Java on November 24, 1925. He was born with the full name Yosaphat Soedarso from a married couple Sukarno Darmoprawiro and Mariyam. Yos Sudarso's father worked as a policeman during the colonial period.

Since childhood, Yos Sudarso was known as a person who was calm, intelligent, and polite in socializing. When he was still a child, he attended HIS (Hollandsch Inlandsch School) school which was at the elementary level, graduating from there in 1940 he then entered MULO (Meer Uitgebreid Lager Onderwijs) in the city of Semarang.

After only five months of going to school, Japan then came to colonize Indonesia. Yos Sudarso finally returned to Salatiga and chose to continue his junior high school education there until 1943. After graduating from there, he then entered a teacher's school in the Muntilan area.

Join the Navy
However, he did not complete his education at the school because at that time there was a transfer of power from the Netherlands to Japan. Finally, Yos Sudarso entered the Maritime High School in Semarang, where he studied for a year and received officer education at Goo Osamu Butai and became the best graduate. His achievements led him to be hired as a pilot on the Goo Usamu Butai ship.

When the proclamation of Indonesian independence was proclaimed on August 17, 1945, Yos Sudarso then joined the Maritime BKR (People's Security Agency), which was later named the Republic of Indonesia Navy Army (ALRI).

Here Yos Sudarso often took part in military missions or operations in quelling rebellions that occurred in the areas at that time. Even though at that time the fleet of ships owned by Indonesia was still very minimal.

In 1950, the Netherlands recognized Indonesian sovereignty. Yos Sudarso was also appointed as the commander of the ship on KRI Alu. Then move to KRI Gajah Mada, KRI Rajawali to KRI Pattimura. Yos even served as a court judge even though it was only 4 months in 1958 to be precise.

In 1959, the internal upheaval in the Navy reached its peak. Yos Sudarso along with Colonel Ali Sadikin and other officers disagreed with the leadership of Admiral Subiyakto, who at that time served as the chief of staff of the navy.
The conflict caused Admiral Subiyakto to be replaced by Colonel R.E Martadinata as the new chief of staff. Not long after that, Yos Sudarso quickly rose in rank from deputy to commodore (first admiral).

The Heroic Story of Yos Sudarso and the Famous Battle of the Aru Sea
In 1961, the confrontation between Indonesia and the Netherlands over the liberation of West Irian from Dutch hands reached its climax. President Soekarno at that time formed the People's Tri Command (Trikora) and the following year, in 1962, Soekarno formed the Mandala Command in the liberation of West Irian with headquarters in Makassar. Yos Sudarso was entrusted with the task of Deputy for Operations.

A tough task for Yos Sudarso. The heroic story of Yos Sudarso's battle finally happened on January 15, 1962. At that time Yos Sudarso was on patrol with three ships namely the KRI Macan Tutul, KRI Macan Kumbang, and KRI Harimau under his command.
The silent operation was carried out around the Aru sea area around the Maluku region. It wasn't long before the Dutch Neptune planes on patrol dropped flares. The situation that was quiet and dark then turned bright. Three Dutch ships with full weaponry and larger sizes then appeared to split the night sky.

The three Dutch ships were already waiting for them. The first warning shot was fired by the Dutch and fell beside the KRI Harimau. Colonel Sudomo then ordered return fire but missed.

Yos Sudarso, who realized that this battle would be unequal in terms of weapons, he then ordered the three ships under his command to temporarily withdraw. A 180-degree maneuver was then carried out by the three ships. But unlucky, the KRI Macan Tutul boarded by Commodore Yos Sudarso got stuck.

The Dutch thought that the Indonesian ships would maneuver to attack. The Dutch then opened fire to attack. KRI Macan Tutul at that time faced a Dutch destroyer. Yos Sudarso then ordered the KRI Macan Tutul to attach the body so that the other two ships could leave the battlefield.

The first shot fired by the Dutch destroyer missed the KRI Macan Tutul. On the next occasion, the shot fired by the Dutch destroyer finally hit the hull of the KRI Macan Tutul, hull number 650.

The death of Yos Sudarso
The West German-made KRI Macan Tutul caught fire and slowly sank to the bottom of the ocean with 24 crew members. The rest of the crew who survived became prisoners of the Dutch. Commodore Yos Sudarso's last sentence just before the ship sank was:
"Stir up the Fighting Spirit" he radioed to the other two ships that had survived.
Commodore Yos Sudarso, who as a child dreamed of becoming a soldier, finally died at sea while defending the sovereignty of the Republic of Indonesia. He left a wife named Siti Kustini and five children. The Indonesian government awarded Yos Sudarso the title of National Hero for his services. His name is also immortalized as a street name in various regions in Indonesia.

Many veils covered the death of Yos Sudarso in the battle at the Arafuru Sea. Starting from the leak of the secret operation by the Dutch, then the government did not know about this operation, such as President Soekarno, as written in the book Conspiracy Behind the Sinking of Matjan Tutul (2011) by journalist Julius Pour.

In addition, the Air Force (Air Force) was accused of being the party most responsible for the incident because it did not provide aircraft assistance which resulted in the removal of KSAU Admiral Suryadarma who was replaced by Lt. Col. Omar Dhani as told in the book Dan Toch Maar! (2009) written by Sukono.
