Abstrak: As one of the factors that influence the dynamics of capture fisheries, the influence of market activities conditions to the dynamics of fishing is still rarely studied. Based on this reason, this study will be conducted to analyze the influence of market activities particularly price fluctuations to the dynamics of capture fisheries and vise versa. To answer these objectives the study was conducted in Brondong Fishing Port. The data was collected by purposive sampling. The result of this study show that the fish distribution between producer and consumer was very simple. Fish landing actually didn’t affect to all fish price significantly. For red snapper and big eye, the number of fish landing negativelly affect to fish price, it mean if fish landing increase the fish price will decrease and vise versa. On the other hand the fish landing of scads, false travelly and yellowtail didn’t affect to fish price significantly. The other result of this study also show that fish price generally didn’t affect to fishing trip.

Judul: Analisis Bioekonomi Ikan Kurisi (Nemipterus Bathybus Snyder, 1911) Yang Didaratkan Di Ppn Brondong, Lamongan
Abstrak: Pelabuhan Perikanan Nusantara (PPN) Brondong merupakan tempat pendaratan ikan yang berada di Lamongan, Jawa Timur. Tujuan penelitian ini adalah untuk mengkaji kondisi sumber daya ikan kurisi yang didaratkan di PPN Brondong berdasarkan aspek bioekonomi. Pada penelitian ini digunakan model surplus produksi dan metode Ford Walford. Hasil menunjukkan bahwa laju eksploitasi ikan kurisi 80,58% per tahun. Hasil analisis bioekonomi menunjukkan bahwa tingkat produksi optimal untuk sumber daya ikan kurisi adalah 104,86 ton/tahun; tingkat upaya optimal untuk pemanfaatan sumberdaya ikan kurisi 24 trip/tahun; dan rente ekonomi optimal untuk pemanfaatan sumber daya ikan kurisi mencapai Rp 3.407.057.824/tahun. Saat ini sumber daya ikan kurisi diindikasikan telah mengalami biological overfishing. Pengelolaan yang dapat disarankan adalah mengurangi hasil tangkapan dengan menerapkan pajak terhadap hasil tangkapan dan selektivitas alat tangkap.

Judul: Elektrodeposisi Film Tipis Semikonduktor Cu2ZnSnS4 (CZTS) pada Substrat Kaca ITO
Abstrak: Semiconductor Cu2ZnSnS4 (CZTS) thin film that can be used as absorber layers on solar cell module was made via electrodeposition method. CZTS thin film was electrodeposited on the surface of a silicate glass coated with a thin layer of indium tin oxide (ITO). Deposition process was done using potentiostatic mode at room temperature with a potential of 1.05 V for 30, 45, and 60 minutes, followed with annealing the film at 2 different temperatures, 500 ºC using furnace and 180 ºC using hot plate, both treatments for 45 minutes in N2/H2S atmosphere. The X-ray difractograms were analyzed using Match 2 program and showed that the CZTS thin films had kesterit crystalline structure, with a low percentage of CZTS phase. The thin film also contained secondary phases such as Cu2S, ZnS, and SnS. The obtained CZTS thin films had a thickness between 1.039 and 1.676 μm. Absorption study showed that the band gap energy of CZTS thin films which was annealed using furnace ranged from 1.50 to 1.52 eV, whereas that annealed using the hot plate was not observed. The band gap energy value showed that CZTS thin films can be used as sunlight absorber layers on solar cell. The formation of CZTS crystal film on this investigation was effectively performed using furnace annealing process at a temperature of 500 ºC with deposition time of 45 minutes.
