Judul: Analysis of Squid Fishing Seasons and Bouke Ami Production Factors in Fisheries Port of Nusantara Kejawanan
Abstrak: Cumi-cumi yang ditangkap oleh armada bouke ami merupakan salah satu hasil tangkapan yang potensial di PPN Kejawanan. Musim penangkapan cumi dibagi menjadi kategori paceklik, sedang, dan puncak berdasarkan hasil tangkapan yang didapatkan. Hasil tangkapan cumi-cumi dapat dipengaruhi oleh berbagai faktor, seperti tenaga kerja, lama waktu trip, perbekalan dan lainnya. Tujuan penelitian ini menganalisis pola musim penangkapan cumi-cumi dan faktor produksi kegiatan operasi penangkapan cumi-cumi yang dilakukan oleh armada bouke ami di PPN Kejawanan. Metode penelitian yang digunakan adalah menggunakan analisis catch per unit effort (CPUE), analisis deret waktu metode rata-rata bergerak, analisis indeks musim penangkapan, dan analisis dekriptif faktor produksi dari data time series laporan tahunan pelabuhan. Berdasarkan nilai indeks musim penangkapan (IMP) yang diperoleh, diduga musim sedang terjadi pada bulan Februari, Maret, April, Mei, Juli, dan Desember. Sedangkan musim puncak terjadi pada bulan Januari, Juni, Agustus, September, Oktober, dan November. Hasil penelitian menunjukkan terdapat beberapa faktor produksi yang digunakan pada kegiatan operasi penangkapan cumi-cumi armada bouke ami di PPN Kejawanan, di antaranya adalah ABK, lama waktu trip, perbekalan air, dan perbekalan BBM. Jumlah penggunaan faktor produksi tersebut cenderung menyesuaikan dengan ukuran dan kapasitas kapal penangkap ikan., Squid from bouke ami is one of the potential catches in PPN Kejawanan. The fishing season is divided into bad, intermediate, and peak categories based on the catch. Several variables might affect squid catches, including manpower, trip duration, supplies, and others. This study aimed to analyze the squid fishing season pattern and the production factors for squid fishing operations in PPN Kejawanan. The research methods applied include the catch per unit effort analysis, time series analysis utilizing the moving average approach, fishing season index analysis, and descriptive analysis factors of production from the port annual report time series data. In the fishing season acquired, it is assumed that the intermediate season runs from February, March, April, Mei, July, and December. While January, June, August, September, October, and November will be the peak seasons. Results of the study showed that there were several production factors used in the squid fishing operation of bouke ami fleet at PPN Kejawanan, including crew members, length of trip, water supplies, and fuel supplies. Amount of use of these production factors tends to adjust to size and capacity of the fishing vessel.

Judul: The Dynamics of Bouke Ami Fishery in Muara Angke Fishing Port
Abstrak: Operasi penangkapan bouke ami membutuhkan modal untuk berlayar yang cukup besar dan dapat menyebabkan kerugian jika pendapatan dari hasil tangkapan lebih kecil dari modal yang dikeluarkan. Perencanaan penangkapan ikan yang di susun berdasarkan dinamika usaha perikanan dapat mengurangi resiko terjadinya kerugian tersebut. Penelitian ini bertujuan untuk mengidentifikasi dinamika usaha penangkapan kapal bouke ami di Pelabuhan Perikanan Nusantara (PPN) Muara Angke sebagai bahan perumusan perencanaan penangkapan ikan. Dinamika tahunan kapal bouke ami di PPN Muara Angke dilihat berdasarkan data hasil tangkapan per trip, jumlah trip per bulan, jumlah pembelian solar subsidi per kapal, dan harga hasil tangkapan terhadap kondisi cuaca di daerah penangkapan. Hasil penelitian menunjukkan periode dengan hasil tangkapan per trip kapal bouke ami tertinggi berada pada periode Oktober-Desember. Pola keberangkatan kapal bouke ami di PPN Muara Angke terjadi pada dua periode, periode pertama pada bulan Februari-Mei dan periode kedua pada bulan Juli-Oktober. Harga tangkapan nelayan bouke ami yang didaratkan di PPN Muara Angke relatif stabil pada saat kondisi cuaca buruk. Kelimpahan hasil tangkapan bouke ami dipengaruhi secara signifikan oleh cuaca namun operasi penangkapan kapal bouke ami tidak signifikan dipengaruhi oleh cuaca karena kondisi daerah penangkapan yang stabil saat kondisi cuaca buruk, Bouke ami fishing operations require considerable operational expenditure and can result in losses if income does not exceed the expenditure. Planning a fishing operation based on its dynamics can reduce the risk of such losses. This study aims to identify the dynamics of bouke ami fishing operation at Muara Angke fishing port as a basis for formulating fishing plan. The research identifies annual dynamics of bouke ami boats in Muara Angke fishing port against weather conditions in the fishing ground on the subject of catch per trip, trip total per month, the subsidized diesel purchases per ship, and catch prices. The results show that the period with highest catch per trip of bouke ami boats is in October-December. The departure pattern of bouke ami boats at Muara Angke occurs in two periods, the first period in February-May and the second period in July-October. The price of bouke ami fishermen's catch landed at Muara Angke fishing port is relatively stable during bad weather. The abundance of bouke ami catch is significantly influenced by the weather but fishing operation is not significantly influenced by the weather since fishing ground condition are stable in bad weather period.

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.
