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: Analisis Produksi Cumi-cumi Unit Penangkapan Bouke Ami di PPS Nizam Zachman Jakarta
Abstrak: Penelitian ini bertujuan untuk menganalisis teknis alat tangkap, produktivitas dan faktor produksi cumi-cumi dari unit penangkapan bouke ami di PPS Nizam Zachman Jakarta. Analisis data yang dilakukan meliputi analisis teknis, analisis produktivitas serta faktor yang mempengaruhi produksi menggunakan analisis OLS. Alat tangkap jaring bouke ami seluruhnya adalah PE (Polyethylene) dengan bukaan mulut jaring mencapai 15 meter dan panjang jaring mencapai 14 meter. Jaring menggunakan tiang gawang dengan bahan bambu sepanjang 17 meter. Fishing ground unit penangkapan bouke ami terletak di perairan pulau Bangka hingga Selat Karimata. Penurunan produktivitas terbesar pada tahun 2013 terjadi pada nelayan. Produktivitas nelayan menurun jauh lebih dari 19% pada tahun 2013 sementara jumlah nelayan mengalami kenaikan mencapai 42,05% pada tahun 2013. Hasil analisis OLS menunjukkan aktivitas trip, jumlah kapal dan musim mempengaruhi produksi cumi-cumi secara positif, sedangkan nilai negatif terlihat pada nelayan yang artinya semakin banyak nelayan pada unit penangkapan maka produksi cumi-cumi akan semakin tidak efisien., This study aims to analyze the technical of catching gear, productivity and factors of squid production by the bouke ami fishing unit in Nizam Zachman Jakarta Ocean Fishing Port. Data analysis was conducted on the technical analysis, analysis of productivity and factors affecting the production using OLS analysis. Bouke ami fishing gear nets are all PE (Polyethylene) with net mouth openings up to 15 meters long and 14 meters of net reach. Nets using a frame with a 17-meter bamboo material. Bouke ami fishing unit's fishing ground is located at the waters of the Bangka island up to Karimata strait. Biggest productivity reduction in 2013 occurred on fishermen. Fishing productivity reduce much more than 19% in 2013 while the number of fishermen has increased up to 42.05% in 2013, OLS analysis results showed activity of trip, number of vessels and season are positively affect the squid production, while a visible negative value indicated by fishermen which means the more number of fishermen on the fishing unit then the squid production will be even less efficient.

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.
