Management blueprint of coastal and marine: concepts of mariculture around sea tin mining activities (case study: Matras Waters, Bangka Belitung Province)

Abstract

Bangka Belitung as an archipelagic province has abundant marine natural resources, including tin reserves and mariculture potential, one of which is Matras waters, Bangka Regency. The exploitation of tin mining in coastal areas will have an impact especially decrease the fish abudance at sea. Therefore, this research was carried out to producing the management blueprint of these two activities in the term of sustainability. The methodologies used in this research are analysis of hydro-oceanographic characteristics, sea water quality conditions and the suitability of mariculture on April 2022. Based on the field data, the quality of sea water in Matras waters can be classified as still quite good where only TSS has a value below the sea water quality standard. However, if we look at the aspect of aquaculture suitability, Matras waters still have the potency for mariculture especially at stations 1 and 2 with suitability scores reaching 76 and 78 which are classified as moderately suitable. In addition, if we look at the legal-socio-economy aspect, clear regulations are needed from the government, both central and regional in managing marine utilization areas such as tightening the implementation of the Approval for the Conformity of Marine Spatial Utilization Activities (PKKPRL).
