Abstract

Prigi waters belongs to the Republic of Indonesia's fisheries management area (FMA 573), which includes the South Indian Ocean of the island of Java to Nusa Tenggara. The species of large pelagic fish occurring in Indonesian waters include tuna comprising: madidihang (Thnunnus albacares), bigeye tuna (Thunnus obesus), albacore (Thunnus alalunga), bluefin tuna (Thunnus maccoyii), long tailed tuna (Thunnus mackerel). The small species of tuna include Skipjack tuna (K. Pelamis), Euthynnus affinis and Auxis thazard caught by purse seine, gillnet, troll line and payang fishing gear. Research purposes were to estimate value of maximum sustainable yield (MSY), total allowable catch (TAC), maximum economic yield (MEY), and open access (OA), to suspect rate and status utilization of Skipjack tuna (K. pelamis). Data analysis in this research was convertion of fishing gear, surplus production model by Schaefer, Fox, and Gordon-Schaefer model. The results of the conversion analysis of fishing gears are determined using a standard fishing gear, which is troll line as fishing gear standard. Result showed that sustainable potential obtained catch and effort of Skipjack tuna (K. pelamis) in MSY condition around 810 ton/year and 2,020 trip/year, and in TAC condition 648 ton/year and 1,616 trip per year, while in bioeconmic analysis in MEY condition was 680 ton/year and 1211 trip/year so that a profit Rp. 4,136,008,186, and in OA condition around 778 ton/year and 2,423 trip/year where the profit obtained Rp. 0. Utilization rate of Skipjack tuna (K. pelamis) was 106% so that the status of the stocks categories was Over Exploited

Abstract

As a maritime country, Indonesia has abundant marine biodiversity, encompassing sea turtles, whose dwindling numbers have serious ecosystem effects. Conservation work is done in various locales, including Pantai Taman Kili-kili, Trenggalek, where the Community Monitoring Group (Pokmaswas) has set up conservation measures. But conservation is hard work, especially doing it well enough so numbers don't keep declining. There's limited human resources and that means conservation in real time works better if done with smart tools. The Pokmaswas needs a system for making recording and reporting almost instantaneous so that any trouble making a dive at the beach is reported posthaste. In developing this system, researchers using the waterfall approach, resulting in a web-based application built using the Next.js framework with an atomic design system. To evaluate system acceptance, Blackbox testing was conducted with 17 test points, achieving a 100% success rate. Whitebox testing included 16 test points, also yielding a 100% success rate. For user acceptance testing, two aspects were assessed: functional and non-functional testing. The functional testing consisted of 14 test points, with a 97.6% success rate. The non-functional testing get 91,7% score
