Judul: Optimizing the service of ambon archipelagic fishing port based on catch supply and demand
Abstrak: Sistem Transportasi perikanan tangkap tidak lepas dari pengkajian dan keterkaitan dari tiga kawasan atau wilayah, yaitu: hinterland, port fishing, dan fishing ground yang terintegrasi sebagai satu kesatuan sistem. Peran pelabuhan perikanan (port fishing) adalah sebagai simpul moda transportasi perikanan tangkap dalam menunjang dan menggerakkan perekonomian utamanya sebagai gerbang dari suatu wilayah yang merupakan tempat embarkasi dan debarkasi bagi komoditi hasil laut laut. Fungsi pelabuhan perikanan yang diharapkan adalah pelabuhan yang mampu memberikan layanan atau kemudahan bagi kelancaran proses produksi, pengolahan serta pemasaran dengan berbagai aspeknya.

Judul: Mooring and Anchoring Services Enhancement for Purse Seiner at Pengambengan Fishing Port
Abstrak: Pelabuhan Perikanan Nusantara (PPN) Pengambengan memiliki fungsi pemerintahan berupa pelayanan jasa tambat labuh kapal perikanan. Jasa tambat labuh tersebut dirasa kurang karena terdapat 20 kapal slerek (Purse Seine) yang memilih untuk berlabuh di luar kolam pelabuhan. Penelitian ini bertujuan untuk mengoptimalkan jasa tambat labuh kapal slerek dengan mengidentifikasi aktivitas pendaratan hasil tangkapan serta faktor-faktor yang mempengaruhi nelayan untuk menambatkan kapal, kemudian dirumuskan strategiyang dapat diambil oleh pihak pelabuhan. Penelitian dilakukan melalui observasi secara langsung dan wawancara terhadap nelayan dan aparatur pelabuhan menggunakan metode purposive sampling. Hasil penelitian menunjukkan bahwa terdapat penurunan pendapatan retribusi sebesar Rp146.804.400,00 per tahun akibat nelayan yang memilih untuk berlabuh di luar kolam. Didapatkan pula faktor yang mengakibatkan nelayan tidak bertambat di dermaga seperti sedimentasi, tarif mahal, letak kapal tidak teratur, dan tidak adanya hukum yang memaksa. Strategi kemudian dirumuskan menggunakan pembalikan akar masalah pada diagram fishbone., Pengambengan fishing port had government function in the form of mooring and anchoring services for fishing vessels. The services was inadequate since there were 20 purse seiners anchoring outside the pool. This research aims to optimize purse seiners mooring services by identify unloading activities and factors that influence fishermen to moor ships, then formulating strategies that can be done by the port. The research was conducted through direct observation and interviews with fishermen and port officials using the purposive sampling method. The results show that there was reduction in income for IDR 146.804.400,00 per year due to fishermen choose to be anchoring outside the pond. It was also found that factors resulted in fishermen not mooring at the wharf, such as sedimentation, high rates, irregular boat locations, and the absence of compelling laws. The strategy was then formulated by reversing the root cause from fishbone diagram.

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.
