<p><em>Community-based Development has been suggested to support the development at the community level. The role of indigenous institutions and the Influence of Culture have been considered in the implementation of Community-based Development approach. An Indigenous Institution of ‘Perelek’ is an institution which has been implemented the principle of ‘gotong-royong’(communality and mutual assistance) among Sundanese people at the rural area of Purwakarta. This tradition also implements the Sundanese cosmology of "Tritangtu". The </em><em>essence of this cosmovision is ‘a harmonious life’ between God, human, and nature. </em><em>By using descriptive analysis, this paper shows that the institution has been contributed to the community-based development in Indonesia, especially after being re-activated by the Purwakarta Government.</em><em> </em><em>The practice of the institution has shown that a bottom-up approach development could effectively support the achievement of development objective – to increase wellbeing- at the community level.</em></p>
