Science and technology in Indonesia part 1

Indonesia is not considered as one of the leading countries in science and technology developments. However, there are many examples of notable scientific and technological developments and achievements contributed by Indonesians. Despite being a developing country, Indonesia is one of a handful nations that have developed their own aerospace technology.

Currently, the republic's Ministry of Research and Technology is the official body in charge of science and technology development in the nation. The government institution dedicated to science and research in the country is the Indonesian Institute of Sciences (Indonesian: Lembaga Ilmu Pengetahuan Indonesia or LIPI). It consists of 47 research centers in fields ranging from social to natural sciences. In 2010, the Indonesian government allocated Rp 1.9 trillion (approximately US$205 million) for research and development—less than 1% of the total state expenditure.


Living in an agrarian and maritime culture, the people of the Indonesian archipelago have become well known in some traditional technologies, particularly in agriculture and marine. In agriculture for instance, the people in Indonesia and many other Southeast Asian countries, are famous for paddy cultivation and techniques such as terracing. Local systems of complex irrigation and water management have been developed in the archipelagos. An exceptional example is Subak, the irrigation system of Bali.

The Bugis and Makassar people from the island of Sulawesi in eastern Indonesia are also well known for their shipbuilding technology. They are renowned for making a wooden sailing vessel called the pinisi boat.[4]

In architecture, native Indonesians have developed their own vernacular architecture. Some examples of architecturally significant Indonesian buildings are Rumah Gadang of Minangkabau, Tongkonan of Toraja, and omo sebua of Nias. The omo sebua is noted for its sturdy yet flexible design which allows it to resist earthquake.

By the 8th century, the Javanese kingdom of Medang Mataram developed an advanced stone mason architectural technology in candi (temple) building. This includes the magnificent Borobudur, Prambanan and many other temples. Architectural techniques that have been developed include knobs, indentations and dovetails used to form joints between stones and bind them without mortar. Other significant architectural advancements include: the roof, niches, and arched gateways constructed in the corbelling method.

Indonesians have also made various advances in food technology, due in part to the tropical climate in Indonesia teeming with various microbes. Indonesians have developed traditional knowledge in fermentation techniques, which resulted in the development of fermented foods such as tempeh, oncom, tapai, and also beverages like brem and tuak. Tempeh is made through natural culturing and a controlled fermentation process, which employs the fungi Rhizopus oligosporus or Rhizopus oryzae,[5] The fungi binds soybeans into a cake form. It has higher content of protein, dietary fiber, and vitamins.[6]

Construction technology

There are some notable technological developments made by natives in modern Indonesia (post independence). In the 1980s, Tjokorda Raka Sukawati, an Indonesian engineer, invented a road construction technique called Sosrobahu. It was popularized afterwards and has since been widely used by many countries. The Sosrobahu technique allows long stretches of flyovers to be constructed above existing main roads with minimum disruptions to the heavy traffic. It involves the construction of horizontal supports for the highway beside the existing road, which is then lifted and turned at a 90 degree angle before being placed on the top of the vertical supports. This forms the flyover pylons. The technology was exported to the Philippines, Malaysia, Thailand and Singapore. In 1995, a patent was granted to Indonesia.[7]

Aerospace and transportation

Indonesia was one of few countries during the 1970s to own their own communication satellite. Since 1976, a series of satellites named Palapa were built and launched in the United States for Indonesia's state-owned telecommunication company, Indosat.
In Internet technology, an Indonesian information technology scientist, Onno W. Purbo developed RT/RW-net, a community-based internet infrastructure which provides affordable Internet access to people in rural areas.[12]
