The people of Tengger and Baduy represent the indigenous communities of Indonesia who still endear themselves to the noble values of their ancestors despite deep globalisation that has triggered changes in customs, behaviours, and traditions among societies. Tengger is considered to be more adaptive to foreign cultures, while Baduy (especially the inner Baduy) is seen to be more protective or even 'preventive' to all forms of new cultures from outside. Peaceful, well-organized, and secure way of life is reflected from these two tribes through good social system. The failure of the Indonesian government to create a miniature laboratory of cultures in capital cities of Indonesia requires more attention. The policy seems to uproot arts and cultures of the nation from indigenous societies in the archipelago. Through the study of legal anthropology, the author came up with the notion of development design for 'an inclusive museum', which stems from local wisdom but still maintains institutional integrity and sensitivity towards native arts and cultures. This inclusive museum is reflected from the 'Sodor dance' of the Tengger society and from a traditional musical instrument called angklung buhun (traditional bamboo musical instrument) of the Baduy society.
