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: Karakteristik Carboxymethyl Chitosan Dengan Variasi Konsentrasi NaOH
Abstrak: Carboxymethyl chitosan is chitosan derivative product obtained from chemical modification. CMCh were made by alkalization process and carboxymethylation process. Factors that affect CMCh characteristics were excess sodium hydroxide in alkalization process, ratio between chitosan and monochloroacetic acid, and carboxymethylation temperature. The objectives of this research were to study the NaOH effect to CMCh characteristics, to learn process of making CMCh, to set the proper concentration of NaOH, and to analyze CMCh characteristics. CMCh yields were 110.72%-114.22%. CMCh pH value were 3.74-4.31. The optimum NaOH concentration to obtain the best CHCh was 10 M. Percentage of CMCh moisture content was 10.70%-11.42%. Ash content and nitrogen content of CMCh were 0.49%-0.50% and 4.52%-4.81%. CMCh viscousity was 8.25 cps. Percentage of CMCh solubility was 61.61%-91.50%. The different functional groups from chitosan which observed in CMCh were C=O group, CH group from alkene functional group, C−O group, and C−O−C group.
