Present day, Indonesia culture is outcome interplay of old traditions from early migrants and western thought brought by Dutch Colonist and Portuguese traders. The basic principle includes the concept of mutual assistance and consultations to arrive at the result. Derived from rural life, this system is still very much use in community life throughout the Indonesia country. Though the legal system is based on Old Dutch penal code and social life as well as the rites of passage is founded on customary or "adat" law, which differs from place to other. The law has been instrumental in maintaining gender equality in Indonesia.
