Indonesia's legal system is based on a hierarchy of laws and regulations. One example of perundang-undangan is the Undang-Undang (Law), which is passed by the Dewan Perwakilan Rakyat (DPR) and the President. Another example is Peraturan Pemerintah (Government Regulation), which is issued by the President to implement laws. There are also Peraturan Presiden (Presidential Regulations) and Peraturan Daerah (Regional Regulations), each serving different purposes within the legal framework.
