Abstrak: Until now, Many Indonesia Fisherman are still poperty and wagging system is some causes of it. The purpose of this research is describe of Fisherman condition and Wagging System, analysis of the best fisherman wagging system, and analysis impact of number of working hours to fisherman income in Tamperan Fishing Port. The data collection metodh use survey metodh with snowball and stratified rundom sampling for choice the sample. The data was analyzed with description analysis, linear regretion and comparation. The result of this research show all of fisheries enterprices use profit sharring system. Many Kind of profit sharring system such as purse seine fisheries have 4 kind, and handline fisheries have 2 kind and traditional fisheries have 4 . Profit sharring in handline is divided by sum of crew. And profit sharring of Tradisional fisheries is devided by kind of instrument catching that use. Handline fisheries profit sharring system become the best profit sharring system in Tamperan Fishing Port after all kind of profit sharrine is caompared with UU RI number 16 1964, and Mudharabah profit sharring system. Number of working hours give impact to fisherman worker excep nakhoda.

Judul: Fair Profit Sharing System between Fishermen and Boat Owners in Drift Gillnet at Karangantu Fishery Port
Abstrak: Kesejahteraan nelayan bergantung pada pendapatan dari hasil produksi operasi penangkapan ikan yang melewati sistem bagi hasil. Pendapatan nelayan jaring rampus rendah diduga sebagai akibat dari sistem bagi hasil yang belum berkeadilan. Tujuan penelitian ini untuk mendeskripsikan kondisi bagi hasil saat ini, menganalisis pendapatan pemilik kapal dan nelayan, serta merumuskan sistem bagi hasil alternatif dengan mensimulasikannya melalui evaluasi UMP dan mempertimbangkan beban kerja, yaitu jam bekerja, risiko kerja, psikologis, dan kenyamanan bekerja. Penelitian dilakukan 29 Januari - 7 Februari 2024 dengan sampel penelitian sebanyak 22 kapal menggunakan metode purposive sampling. Hasil penelitian menunjukkan sistem bagi hasil saat ini 50% pemilik kapal dan 50% nelayan. Namun, pendapatan ABK saat musim sedang Rp 2.424.048 tidak mencapai UMP Banten Rp 2.661.280 dan mengalami kerugian saat musim paceklik. Oleh karena itu, diperlukan sistem bagi hasil alternatif dengan pertimbangan jam bekerja, risiko kerja, psikologis, dan kenyamanan bekerja. Hasil penelitian diperoleh proporsi 37% pemilik kapal dan 63% nelayan. Proporsi jaring rampus tersebut menunjukkan pendapatan nelayan saat musim sedang Rp 3.054.300 di atas UMP dan pendapatan bersih pemilik kapal Rp 7.222.605 tetap mendapat keuntungan Rp 4.584.461 di atas BEP. Namun, musim paceklik tetap mengalami kerugian sehingga dibutuhkan strategi pekerjaan alternatif saat musim panceklik pada penelitian berikutnya.

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.
