The purpose of this research is to analyze the efforts of the Indonesian Government through the Ministry of Communications and Informatics on developing infrastructure to increase internet access in unreached areas and to analyze the actions of the private sector in developing ICT infrastructure to aid in leveling access to the internet in the unreached areas of Indonesia, both in which as part of the Universal Service Obligation (USO). The research method used is a normative research, which uses the legislation of the Republic of Indonesia based on the hierarchy and applying the legal rules to analyze the problem(s) of the research. The result of the research is first, the Government’s effort on developing infrastructure based on the current regulation and strategic plan to reach its goals during this 5-year development period to increase the penetration of internet users in the unreached areas. Secondly, the effort from the private sector to participate in developing ICT infrastructure by collaborating with the Government through Public-Private Partnerships (PPP) in order to reach the same goal to increase the usage of the internet in the unreached areas of Indonesia.
