The multiparty system is an obstacle that must be addressed. One of the instruments that can be used to transform the party system and presumably strengthen the presidential system implemented in Indonesia is the parliamentary threshold (Parliamentary Threshold). The parliamentary threshold is believed to be able to reduce the number of political parties that will enter representative institutions. So that there will be a simplification of the number of parties in the DPR with fewer parties, the support for the party system to the building of the presidential system that is adopted will be stronger. The research method used in this study is a Literature Review of various journal articles and books on Parliamentary Thresholds. The results of this study are the consequences of the multiparty system not only affecting the mechanism and efficiency of the discussion of draft laws and draft regional regulations in the DPR or DPRD, but also the government bureaucracy that must be held by many people as representatives of the winning political parties in the general election. People's representatives who sit in the legislature and government will fight for the aspirations of their supporters who are very varied. Among the impacts of the multiparty system that is important to note is the necessity of forming a governing coalition, which in practice in the past made it difficult for the government to set strategic policies because it took into account many factors.
