The construction of electric power plants is needed to meet national electricity needs and as far as possible is planned optimally with the principles of the lowest cost. The construction of power plants prioritizes the utilization of local energy sources. One of the power plant construction projects is PLTU Tanjung Jati- B units 5 and 6, Tubanan Village, Kembang Sub-District, Jepara Regency, Central Java Province. This project carries out community empowerment/unskillled labor in the construction phase. This study analyzes critical success factors (CSFs) and data collection is conducted through a questionnaire survey of respondents from community/unskilled labor. Research results show 10 critical success factors, which include the development of skills and quality of human resources through training; cost, quality and time control; the functioning and benefit of the constructed infrastructure, where infrastructure construction affects economic and social systems in the surrounding environment; human resource development through case studies; financial compensation received (direct payment); commitment of members of organizations; identification and allocation of risks; accuracy of the choice of technology used; timeliness in completing work; implementation of occupational health and safety programs.
