Abstract: Although the District Government of Southwest Maluku and West Southeast Maluku both want the gas industry in the Masela Block to be built in their respective areas, it is necessary to know the extent or perception of the people of Southwest Maluku Regency and Southeast Maluku West. Because without the interest or agreement of the people in each region (considering the impact problems from various fields), it is feared will give a new problem when the Masela Block has started to operate that is the emergence of protests from the surrounding community. For that socialization of the government associated with the construction of the Masela Block is very necessary to do. This research is conducted to answer how big the role of socialization done by the current government to the society perception about the impact of Masela Block development, if it is built in Southwest Maluku Regency and in West Southeast Maluku. In addition, this study also aims to determine whether the public perception of the impact of the Masela Block development currently affects the interest of each region’s community to build the Masela Block in its area. Given the great interest of the community to build the Masela Block, it is hoped that it will minimize protests from the community towards the construction of the Masela Block in the future. This study uses a quantitative approach with Partial Least Square analysis. The results of this study indicate that the socialization of the Masela Block development has an important role to form the community perception related to the development of the Masela Block. In addition, community perceptions related to the development of the Masela Block are also significant enough to affect their interests in order for the Masela Block to be built in their areas, whether in West Maluku and Southwest Maluku districts. As well as the perception of the community plays a role as a mediation variable between socialization and interest, so that in order not to occur later in the conflict with the community then the development of the Masela Block must be socialized first to the community. We do not know which of these two areas will be chosen by President Jokowi, but the effect of socialization is very big role to the formation of perception so as to generate public interest in both places related to the development of Masela Block.
