Judul: Analisis kebijakan pengelolaan perikanan tangkap berkelanjutan di Kabupaten Indramayu
Abstrak: Pembangunan perikanan pada masa lalu belum dapat memecahkan berbagai permasalahan yang dihadapi, diantaranya adalah rendahnya tingkat kesejahteraan nelayan dan adanya indikasi tangkap lebih (over fishing) di beberapa wilayah perairan seperti Selat Malaka dan pantai Utara Pulau Jawa. Permasalahan lain yang timbul adalah kecenderungan beberapa daerah menjadikan sumberdaya ikan (SDI) sebagai sumber utama Pendapatan Asli Daerah (PAD). Keadaan ini dikhawatirkan dapat menambah tekanan terhadap SDI akibat penangkapan ikan yang tidak terkendali karena tidak memperhatikan prinsip pembangunan berkelanjutan. Kabupaten Indramayu merupakan salah satu kabupaten di Provinsi Jawa Barat yang memberikan sumbangan terbesar terhadap produksi perikanan yaitu sekitar 43% dari total produksi perikanan tangkap Provinsi Jawa Barat. Pada tahun 2004 tingkat pemanfaatan SDI sebesar 203, 91% dari nilai MSY atau sebesar 32.754 ton. Penelitian ini bertujuan mengkaji status keberlanjutan perikanan tangkap di Kabupaten Indramayu, mengkaji faktor-faktor pengungkit yang berpengaruh serta menentukan strategi pengelolaan perikanan tangkap di Kabupaten Indramayu. Metode yang digunakan adalah Rapid Appraisal for Fisheries (RAPFISH) untuk mengetahui status keberlanjutan perikanan dan Data Envelope Analysis (DEA) untuk mengetahui jumlah alat tangkap yang optimal. Hasil analisis menunjukkan bahwa status perikanan tangkap di Kabupaten Indramayu tidak berkelanjutan baik ditinjau dari aspek ekologi, ekonomi, sosial, teknologi, etika maupun kelembagaan dengan masing-masing nilai indeknya di bawah 50, yaitu indek ekologi 25,27 – 26,34; ekonomi 39,72 – 39,95; sosial 43,10 – 43,61; teknologi 38,00 – 38,08; etika 29,33 – 30,85 dan kelembagaan 37,32 – 37,44 pada selang kepercayaan 95%. Hasil analisis menunjukkan tekanan lahan mangrove, besarnya subsidi, tingkat pendidikan yang rendah, mitigasi habitat dan transparansi merupakan faktor pengungkit utama. Terdapat 8 jenis alat tangkap utama yang digunakan para nelayan Indramayu yaitu purse seine, gillnet, lampara, jaring klitik, pancing, sero, pukat pantai dan dogol. Jumlah alat tangkap tersebut saat ini berdasarkan hasil analisis sudah melampaui carrying capacity yang ada. Alat tangkap yang efisien dengan nilai efisiensi 100% adalah jaring klitik, payang, gillnet, dan purse seine. Sedangkan, Alat tangkap yang tidak efisien adalah dogol (80%), sero (76,83%), pancing (66,55), dan pukat pantai (46,16%). Kondisi ini menunjukan bahwa alat-alat tangkap yang memiliki daerah penangkapan di luar Kabupaten Indramayu umumnya lebih efisien. Langkah-langkah kebijakan yang diperlukan dalam pengelolaan perikanan tangkap di Kabupaten Indramayu adalah (1) konservasi dan rehabilitasi hutan mangrove, (2) pengaturan jumlah alat tangkap, (3) penanganan pasca panen, (4) modernisasi armada besar yang beroperasi di wilayah lepas pantai, (5) pengurangan armada kecil yang tidak efisien dan tidak ramah lingkungan, (6) pengembangan industri pengolahan ikan, (7) peningkatan kapasitas kelembagaan perikanan dan kelautan, (8) penyediaan mata pencaharian alternatif, dan (9) program pengkayaan stok.

According to DPK of Indramayu Regency (2010a), the production of sea fishery in Regency of Indramayu is stable at 2009 reaching 108.554,6 ton with value about Rp 1.383.687.650.000. That production must influence stock capacities of fish resources in fishing ground, so that its exploiting require to be controlled, inclusive maximum economic yield (MEY). The aim of the research to analyse stock capacities and maximum economic yield of fisheries resources, to analyse sustainability of fisheries effort, and to formulate the development strategic of sustainable economic based on fisheries effort in Indramayu Regency. Drift gillnet (JIH), set gillnet (JIT), payang, bottom long line, handline, dan shrimp gillnet (JK) can be laboured on an ongoing basis in Indramayu Regency. Economi interest of drift gillnet (JIH), set gillnet (JIT), payang, bottom long line, handline, dan shrimp gillnet (JK) each are Rp1.029.134.326, Rp 579.915.247, Rp 992.640.822, Rp 263.338.992, Rp 56.725.341, dan Rp 76.184.501.

Judul: Enhancement of photon absorbtion on BaxSr1-xTiO3 thin films semiconductor using photonic crystals.
Abstrak: In this research, has been conducted BaxSr1-xTiO3 (BST) thin films manufacturing for mole fraction x = 0.25, 0.35, 0.45, and 0.55; and concentration of 1 molar using chemical solution depositon (CSD) method. The materials, which are used in this research, are barium acetate [Ba(CH3COO)2, 99%], strontium acetate [Sr(CH3COO)2, 99%], titanium isopropoxide [Ti(C12O4H28), 97.999%], gallium trioxide [Ga2O3], 2-methoxyethanol [H3COOCH2CH2OH, 99%] and 1 x 1 cm of transparent conductive oxide (TCO) glass as substrate. Two BST thin films are made that for BST thin films which are doped by 10% galium (BGST) as p-type layer and pure BST solution as n-type. BST solution is made by reacting barium acetate [Ba(CH3COO)2, 99%], strontium acetate [Sr(CH3COO)2, 99%] and titanium isopropoxide [Ti(C12O4H28)] into 2-methoxyethanol solvent [H3COOCH2CH2OH, 99%] in accordance with mass gram for each x value. While, BGST solution is made in the same way as BST solution, plus adding gallium at 10% of the mass of BST. Once all materials are reacted, then vibrated using ultrasonic for 90 minutes, and followed by coating BGST / BST on the TCO substrate. Once the layer is formed, then annealed for 15 hours at temperature of 500 °C with increasing rate of 1.67 oC/minute. Characterizations of BST thin films with or without photonic crystals include the absorbance and transmittance in the visible light spectrum, as well as the electrical photoconductivity characterizations. From BST thin films without photonic crystals indicate that our thin films have light absorption area on almost the entire range of the visible light spectrum even to the infrared range with absorption value over than 67.6%, in addition, it can be seen that the maximum absorbance of BST thin films for all mole fractions lie in blue to green light spectrum region, 457 nm ≤ λ ≤ 570 nm and the minimum in yellow to red light spectrum region, 570 nm ≤ λ ≤ 678 nm. The largest absorbance is found at x = 0.25 with average absorbance value of 92.04% and maximum and minimum absorbance peaks at wavelength of 500.89 and 657.72 nm, respectively. At x = 0.35, average absorbance value decreased to 83.55% with maximum and minimum peaks at 505.73 and 613.68 nm, respectively. Then increased to 91.16% at x = 0.45 with maximum and minimum peaks at 506.04 and 618.56 nm, respectively. At x = 0.55, average absorbance value decreased to 80.12% with maximum and minimum peaks at 507.85 and 608.79 nm, respectively. Moreover, it can be seen that the addition of barium mole fraction leads to wider maximum absorbance or minimum transmittance peaks and narrower minimum absorbance or maximum transmittance peaks in the same range of the green and blue & red light spectrums, respectively. BST thin films with photonic crystals show increasing in absorption for all x values in the range of 3.04 into 13.33%. At x = 0.25, average absorbance percentage increased 3.96% from 92.4 into 95.68%, for x = 0.35 average percentage increased 7.07% into 89.45 from 83.55%. Furthermore, average absorbance of BST thin films at x = 0.45 increased 3.04% from 91.16 into 93.93% and x = 0.55 has
