National development often causes various kinds of problems. The problems happen because the policies about national development made by the Indonesian government tend to take sides with businesspeople and impact on the oppression of the society. National development argued for the society’s welfare eventually turns out to be detrimental for the society and threatens the survival of the society. Moreover, it tends to destroy the natural environment where the society depends its life. Currently, there are many natural resources that should be used as much as possible for the society’s welfare. However, many of those natural resources are controlled by businesspeople that are regulated in the free market and camouflaged in democratization existence. The Indonesian government, which is supposed to have a significant role in protecting the society, evidently takes sides with businesspeople in the interest of seeking financial benefits without paying attention to various aspects of the society’s life. This condition has brought several kinds of the society’s social movements as the response to neoliberalist policies that basically eliminate the concept of the society’s sovereignty. The social movement conducted by the society of the southern coastal area of Yogyakarta, as a discussion focus of this paper, is a form of the society’s response to the government’s policies related to national development in the iron sand mining construction project that tends to take sides with businesspeople and harms the society in many aspects.
