In the international community. Indonesia is one of the country that quite active involved in international cooperation forums. One of the forums is South-South and Triangular Cooperation (SSTC), a new cooperation framework in political, economic, social, cultural and technical area between at least two developing countries and one developed country. In order to support SSTC, the Government of Indonesia formed the National Coordination Team on SSTC. In its implementation, the National Coordination Team (NCT) on SSTC has not shown satisfactory results due to the lack of coordination among the Ministry involved. As a result, the programs that exist today are mostly not linked to each other, not sustainable, and not providing the maximum impact for Indonesia. To make coordination in NCT easier, we proposed to create an integrated information system that supports all of cooperation process. This research tries to design an integrated information system software that can support SSTC program in Indonesia, using RUP (Rational Unified Process) method. The results of this research will be presented as a draft of system specification, and ready to use as an initial design of the software. With the implementation of integrated information system software, we expect that all cooperation programs conducted by Indonesia can linked to each other, sustainable, and bring maximum impact for the Indonesian progress.
