Judul: Keragaan Mesin Penggerak Perahu Motor Tempel di PPI Pasauran, Serang, Banten
Abstrak: Outboard engine is used by the majority of fishermen in Indonesia. Therefore, it is necessary to do research about performance of outboard engine. This research is conducted in PPI Pasauran Serang Banten. The objectives of this research to identify part of outboard engine, calculate with theorist method the best speed for outboard vessel in PPI Pasauran, and to calculate with theorist average amount of fuel that needed by outboard fishing vessel per trip in PPI Pasauran. Data analysis is being done with comparative-numeric between marine outboard engine and long shaft outboard engine. Outboard engine are consist of motor, shaft of propeller, propeller, and carburetor. Best theorist speed that used by PPI Pasauran Fishermen to operate marine engine outboard are 4,59-4,72 knot and to operate long shaft outboard engine are 4,04-4,27 knot. Theorist amount of fuel that needed by marine engine outboard fishing vessel are 40-60 liter per trip and theorist amount of fuel that needed by long shaft outboard fishing vessel are 6-12 liter per trip.

Judul: Keragaan Teknis Kapal Motor Tempel di PPI Pasauran
Abstrak: Informasi tentang keragaan teknis kapal di suatu daerah diharapkan dapat memberikan gambaran tentang kecenderungan dimensi dan bentuk dari kelompok kapal daerah tersebut. Oleh karena itu perlu dilakukan kajian yang terkait dengan jumlah dan karakter teknis sebuah kapal di suatu daerah tertentu. Dalam kajian ini, lokasi kajian terletak di PPI Pasauran, Serang, Banten. Tujuan dari penelitian ini adalah menghitung jumlah perahu motor tempel dan mengidentifikasi keragaan teknis perahu motor tempel di PPI Pasauran Serang Banten. Pendataan kapal dan pengukuran dimensi utama kapal dilakukan secara sensus. Adapun data yang dikumpulkan terdiri dari data jumlah kapal dan ukuran dimensi utama kapal. Berdasarkan hasil kajian diketahui bahwa jumlah perahu motor tempel sebanyak 80 unit yang terdiri dari 53 perahu motor tempel besar dan 27 perahu motor ketinting. Perahu motor tempel besar memiliki bentuk yang cenderung gemuk, adapun perahu motor ketinting cenderung berbentuk ramping.

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.
