Why is Satellite Palapa Day on 9 July? A Look at Its History and 20 Greetings

9 July marks Satellite Palapa Day. This moment refers to the launch of Palapa A1, Indonesia’s first communication satellite, which became an important milestone in the nation’s telecommunications history. Historically, the Palapa A1 satellite was launched from Cape Canaveral, United States, on 8 July 1976 local time. Due to the time difference, the launch coincided with 9 July 1976 in Indonesia. According to the book ‘Sejarah Satelit Palapa Indonesia Seri I’ by Mulyadi, the Palapa Satellite was one of Indonesia’s major projects to build a communication system capable of reaching the entire archipelago. As is known, Indonesia’s archipelagic shape requires a sophisticated communication system to cover all areas. The history of Satellite Palapa Day is inseparable from the launch of Palapa A1, a crucial milestone in the development of Indonesian communication technology. As an archipelagic nation, Indonesia faced challenges in building inter-regional communication networks. The country’s vast territory, separated by oceans, made the need for a reliable communication system imperative. The Palapa satellite was part of Indonesia’s effort to build a domestic satellite communication system capable of reaching the entire Nusantara. Its presence marked a major step for Indonesia into the era of satellite-based communications. According to the official website of Djuanda University, the idea for the Palapa satellite emerged when the second President of Indonesia, Soeharto, contemplated how to communicate across the country’s vast, water-separated regions. Soeharto then assigned Major General TNI Soehardjono and Ir Sutanggar Tengker Yahya to manage the satellite project. In short, the satellite project was completed in approximately 17 months. During the process, the government partnered with the Hughes Aircraft Company from the United States to design and manufacture the satellite. The name Palapa itself was taken from the Palapa Oath declared by Patih Gajah Mada of Majapahit. The name was used to symbolise the spirit of uniting the Nusantara through communication technology. 9 July was designated as Satellite Palapa Day because on that day the launch of the Palapa A1 satellite occurred. Indonesia’s first satellite was launched by an American rocket over the Indian Ocean at 83 degrees East Longitude. The Palapa Satellite holds very significant meaning for Indonesia, serving as a symbol embodying the nation’s advancement in communication technology. At that time, building a communication network was extremely difficult given Indonesia’s vast expanse from Sabang to Merauke. Land infrastructure was also incapable of reaching small islands. Referencing Djuanda University, Indonesia became the first country in Asia and the third country to successfully operate a Domestic Satellite Communication System using a Geostationary satellite, after the United States and Canada. Palapa A1 provided the initial service that supported the beginnings of intercity telephone and facsimile services in Indonesia. Therefore, the Palapa Satellite is not merely a technological device but also a symbol of Indonesian unity, strength, and information. Palapa A1 was Indonesia’s first domestic communication satellite and was similar to the domestic satellites used by Canada and the United States because it was made by the same company, Hughes Aircraft Company, using the HS-333 model. The Palapa A satellite had 12 transponders, a capacity equivalent to 6,000 voice circuits or 12 colour television channels, an active lifespan of up to seven years, a height of 3.41 metres, a diameter of 1.9 metres, and a launch weight of 574 kilograms. The Palapa satellite was controlled by PERUMTEL, which has now transformed into TELKOM. Its services covered Indonesia and several Southeast Asian countries, such as Singapore, Malaysia, Thailand, and the Philippines.
