Abstract: Maren social empowerment program (Program Pemberdayaan Masyarakat Maren (P2MM)) is a pro-poor oriented policy that is implemented based on Decree of Tual Mayor No. 86 of 2013. In relation with effectiveness and efficiency of implementation of the program, it is necessary to recognize the affecting factors. Therefore, researchers were interested in two factors that take part in determining the success of the program, i.e., administrative communication and public participation. Thus, this thesis is titled “Effect of Administrative Communication and Public Participation on Public empowerment in Maren Program at Tual City, Maluku Province.” This study was intended to determine whether there is effect and how significant is the effect of administrative communication and public participation on public empowerment in Maren Program. This study used explanatory method with quantitative approach. Data was collected by using questionnaire and document study and processed by using inferential statistic analysis and parametric statistic analysis. The result shows that administrative communication has positive and significant influence on public empowerment with correlation coefficient by 0.572 and coefficient of determination by 0.2417 or significance by 24.2% public participation has positive and significant influence on public empowerment with correlation coefficient by 0.516 and coefficient of determination by 0.164 or significance by 16.4% and administrative communication and public participation simultaneously have positive and significant influence on public empowerment with correlation coefficient by 0.637 and coefficient of determination by 0.406 or significance by 40.6%. From this study, it is recommended to optimize administrative communication and public participation both partially and simultaneously to improve the implementation of public empowerment programs, especially the P2MM. Concerning administrative communication, it is necessary to be improved in terms of several weaknesses such as ability of communicator (government) to convey messages and public ability to receive information. As for public participation, it is necessary for public to be given more attention and more spaces to participate actively in national development. Intensive and periodic monitoring and evaluation is also required for successful implementation of program.
