Fishing and its related produce has been identified as the main home industry in this village. One of the most popular fish produce is fish cracker managed by Hj. Asfiah. The main ingredient of this product is milk fish (chanos-chanos) and otek fish (Osteogeneiosus militaris). In order to identify the internal and external strategy of this business, the SWOT analysis was applied to evaluate strength, weakness, opportunity and threat that might affect the business sustainability. The analysis indicated that the strength and opportunity (S-O) is essential and need to be managed. Based on the estimation values, this business is feasible and scale improvement is necessary.","PeriodicalId":123293,"journal":{"name":"Jurnal Ilmu Perikanan Tropis Nusantara (Nusantara Tropical Fisheries Science Journal)","volume":"67 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-01-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"120986578","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

According to the result, the coral reef in Sangkulirang and Sandaran District both in same condition that categorize into fair/moderate condition with each coverage of HCL 48.1% and 41.4%, and the combine in average HCL 45,9% also in the same category.  Overall of both districts estimated had 2,221.57 ha of coral reef area with condition vary from poor/bad till good category.  761.27 ha of coral reef was estimated in Sangkulirang District and 1,460.30 ha in Sandaran District.  The coral reef area in both districts commonly forming a narrow stretch of reef develop along the edge of drop-off bathy profile. Factors of limitation and degradation toward the coral reef development in both districts are: i) non-anthropogenic (nature) factor, majority the turbidity and sediment load from river estuaries and sea current and wave, and ii) anthropogenic (human) factor in activities of destructive fishing method especially by explosive fishing.","PeriodicalId":123293,"journal":{"name":"Jurnal Ilmu Perikanan Tropis Nusantara (Nusantara Tropical Fisheries Science Journal)","volume":"69 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-01-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124445285","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
