Based on the review of Indonesian Parliament's institutional history, its oversight functions existence largely determines good or poor condition of democracy and implementation of good governance principles. When it is weak or weakened, the ruling regime would tend to move away from the principles of democracy. Joko Widodo's governance conditions that tend to embrace many coalition partners in parliament, requiring revision of laws (political party and election law) in order to provide vast opportunities for the criticism measures and corrective actions from political parties, which do not collaborate with the government. Improvement of legislation should be directed to guarantee freedom of movement of political parties that do not form a coalition with the government. Therefore, those political parties can fulfill the role of a healthy opposition. Even if the parliament opposition raises have not yet to be adopted within the Indonesian governance system, at least a revision of the law aimed at guaranteeing the members of parliament (MPs) to perform their role freely according to conscience. While it cannot be separated entirely from the parties which supporting him, but the threat to be fired (recall) should be eliminated. So that MPs can still carry out the oversight role despite their political party collaborated with the government. This revision can create the oversight function of DPR as a form of real performance of a representative body to accommodate the interests of oversight of the Indonesian people, also become a reliable tool of facing the challenges of Indonesian democracy.
