Abstract:
Textile dye is a material that has a negative effect on environmental quality, one of the textile dyes is violet crystal. Biodegradation is one of the methods that used in waste treatment and can take advantage of microbial activity to degrade waste. Mangroves are ecosystems that are found along coastal waters in tropical and subtropical areas. Microorganisms such as bacteria are able to live and develop in mangrove roots. This study aims to isolate and identify the bacteria that live on mangrove roots morphologically and are able get degrade textile dyes. This research was conducted using experimental laboratory methods. Samples were isolated from mangrove roots obtained in Wonorejo Surabaya sterilely. The process of isolation and verification of bacterial morphology was carried out at the Microbiology Laboratory of Hang Tuah University, Surabaya. The method of isolation was carried out using the spread method, and the purification of the bacteria was carried out using the streak method. The results obtained 10 bacterial isolates from the results of isolation and morphological examination, while 2 isolates were able to degrade the violet crystal textile dye, called AB.1.2 and AB.1.5 which were indicated by the presence of clear zones.

Abstract:
Currently, most food products circulating in the community are processed using additives, both natural and synthetic. One of the potential food ingredients that can be used as a natural flavor enhancer from fishery raw materials is long jawed mackerel (Rastrelliger spp). The purpose of this study was to studied preliminary research on the use of long jawed mackerel as an alternative material for natural non-MSG flavorings to replace synthetic flavors with a fisheries bioeconomic approach. The procedure in this study consisted of several steps, namely the manufacture of natural flavorings from long jawed mackerel, calculation of fish yield, analysis of water content and salt content (NaCl). Based on the research results, the processing stages of non-MSG natural flavoring made from long jawed mackerel fish include the process of selecting raw materials, washing I, filling, washing II, refining I, weighing I, drying, refining II, sifting, weighing II and packaging. The amount of long jawed mackerel yield that can be used as the main raw material for the manufacture of natural non-MSG flavorings is 53% with the final weight of flavoring powder produced is 440 grams. The chemical analysis test of the long jawed mackerel flavoring was carried out 2 repetitions and the results of the water content test were 5.35% (has not met the SNI quality requirements), while the analysis of salt content (NaCl) on the long jawed mackerel flavoring has met the SNI quality requirements with a value of 12.09%. Bioeconomic analysis of fisheries is by calculating production costs and depreciation costs incurred during the processing of flavorings from long jawed mackerel. Based on the analysis, one production time produces 88 pcs of flavoring fish meat with a cost of production of Rp. 1,496 per pcs.

Abstract:
Penelitian ini dilakukan selama 3 bulan yaitu bulan April sampai Juni 2019. Tujuan penelitian ini untuk mengetahui pengaruh waktu hauling terhadap hasil tangkapan jaring rampus di Pelabuhan Perikanan Pantai (PPP) Bondet. Perendaman alat tangkap jaring rampus dilakukan selama 30 menit, jarak tempuh fishing base ke fishing ground memerlukan waktu 1-2 jam dan setting dilakukan pada jam 05.30 kemudian pengangkatan jaring dilakukan pada pukul 06.00. Metode penelitian yang digunakan adalah experimental fishing, yaitu dengan melakukan kegiatan operasi penangkapan ikan di laut dengan menggunakan jaring rampus. Adapun hasil penelitian yaitu dari hasil tangkapan selama 5 kali trip menghasilkan trip ke 1 sejumlah 13,84 kg dalam waktu 120 menit, trip ke 2 sejumlah 5,97 kg dalam waktu 75 menit, trip ke 3 sejumlah 10,45 kg dalam waktu 110 menit, trip ke 4 sejumlah 10,85 kg dalam waktu 115 menit, trip ke 5 sejumlah 13,55 kg dalam waktu 120 menit. Dari hasil tersebut di atas dan berdasarkan Analisis Regresi Linier sederhana diperoleh bahwa F hitung sebesar 24,31 dan F tabel 7,71 yang berarti F hitung lebih besar dari F tabel. Dari output tersebut dapat diketahui nilai F hitung = 24,31 dengan nilai signifikan F hitung > F tabel, maka H0 di tolak dan H1 diterima yang berarti ada pengaruh yang nyata (signifikan) variabel waktu (X) terhadap variabel hasil tangkapan (Y). Adapun persamaan regresi adalah Y = -5,326 + 0,147 (X), dimana Y adalah hasil tangkapan X waktu (hauling). Dengan demikian setiap kenaikan 1 (satu) menit X (waktu) akan menaikkan variabel Y (hasil tangkapan).
