Tin mining activities in Belitung Island have lasted since colonialism era to this moment. In 1990s tin exploitation in Belitung was stopped as it was assessed as no longer productive. In 1999, however, the mining had massively recommenced and at the same time, tourism and fishery were being actively developed as the new economic power. Recently, tin exploitation has shifted into offshore, and since then the conflicts began to appear. Rejection actions were continuously performed by fishermen through anti offshore mining audience, demonstration and campaign in social media. One of the rejections was when production suction vessel entered Pering waters, KelapaKampit East Belitung. At the urging of local fisherman group, written agreement between East and West Belitung head regencies, as well as the special committee recommendation of East Belitung house of representative, finally the suction vessel moved out from Pering waters. This study aimed to analyze fishermen’s and stakeholders’ knowledge, attitude, and expectationtoward offshore mining activities. Their point of views are needed in order to obtain complete perspective regarding the positive and negative sides, whether there is the meeting point among various interests and how long this conflicts will last. It is a mixed method research between qualitative and quantitative one. Quantitative approach employed questionnaire and SPSS 20 was used to analyze the results. Data collection technique used non-probability sampling with specific characteristic, fisherman community in Pering coastal area in which the amount applied Solvin theory. Qualitative approach was used to explore various phenomenons developing in society through interview with stakeholders related to offshore mining issues.
