Judul: Analisis Teknis dan Ekonomi Perikanan Pancing Layang- Layang di Perairan Banten.
Abstrak: This study aimed to analyze the technical performance of kite fishing units and calculate its productivity and financial analysis of the its operation in the Banten waters. This research was conducted using a case study method and data were collected using purposive sampling method. Technical and financial analysis were used. In this research kite fishing units were divided into two groups, namely the kite fishing units with outboard engine and without engine. Kite fishing units consisted of rollers, rods, lines, kites and baits. There was a kolong-kolong which was functioned to catch fish by using another fish named renyok as baits. Profit from kite fishing units with outboard engine was Rp 24.764.500,00 per year, it was higher than the ones without outboard engine which was Rp 6.982.388,89 per year. Kite fishing units were feasible to be developed, as the value of R/C ratio was 2,54 and 1,70; moreover its pay back period was 2 - 3 months

Judul: Biotechno Economic Analysis of the Fishing Unit at the  Cilauteureun Coastal Fishing Port, Garut Regency, West Java
Abstrak: Unit penangkapan ikan di Pelabuhan Perikanan Pantai (PPP) Cilauteureun terdiri dari gill net, mini purse seine dan pancing rawai. Potensi sumberdaya perikanan laut di Cilauteureun diantaranya yaitu jenis ikan pelagis besar dan ikan pelagis kecil. Penelitian ini bertujuan menganalisis alat penangkapan ikan ditinjau dari aspek biologis, teknis dan kelayakan usaha penangkapan ikan. Pengumpulan data dilakukan menggunakan metode accidental sampling. Alat tangkap yang berada di PPP Cilauteureun merupakan alat tangkap yang produktif. Alat tangkap yang memiliki produktivitas tertinggi yaitu mini purse seine. Hal ini terlihat dari rata-rata nilai produktivitas mini purse seine pada tahun 2018-2021 yaitu 11.503,62 kg/unit, sedangkan produktivitas alat tangkap pancing rawai sebesar 6.724,52 kg/unit dan gill net 8.007.06 kg/unit. Hasil analisis skoring aspek biologi dan teknis, diperoleh bahwa pancing rawai merupakan teknologi tepat guna untuk dioperasikan di perairan Cilauteureun. Berdasarkan analisis keuangan, keuntungan yang diperoleh usaha perikanan gill net yaitu Rp 81.284.104, mini purse seine Rp 109.875.856 dan pancing rawai Rp 34.930.139. Nilai R/C yang didapat dari masing-masing unit penangkapan ikan menghasilkan penerimaan sebesar 1.35 untuk gill net, R/C 1.17 pancing rawai serta 1.29 untuk mini purse seine. Nilai payback periode untuk gill net sebesar 3.17, mini purse seine sebesar 3.23 dan pancing rawai sebesar 5.44

Judul: Hydroxyapatite-Chitosan Composite Coating on Stainless Steel 316 to Improve Corrosion Resistance
Abstrak: Metals that were used in bone implantation should have good corrosion resistance that were not easily corroded when implanted into the body. Metal corrosion resistance of stainless steel 316 can be enhanced through the metal coating by hydroxyapatite-chitosan composite with composition ratio of hydroxyapatite (gram) and chitosan 3% (mL) 0.2:0, 0.2:0.1, 0.2:0.5, 0.2:1.0, and 0.2:1.5. Besides improving the corrosion resistance of metal, the presence of chitosan also maintain the position of hydroxyapatite on metal surfaces. Corrosion resistance increases with increasing amount of chitosan added and the best composition of hydroxyapatite-chitosan composite was 0.2:1.0.
