Judul: A design of sustainable predictive model for capture fishery agroindustry
Abstrak: Potensi keunggulan komparatif sumber daya perikanan Indonesia sudah selayaknya diikuti dengan upaya pengembangan agroindustri perikanan tangkap secara berkelanjutan untuk meningkatkan keunggulan kompetitif sektor perikanan. Upaya tersebut diharapkan dapat mempercepat terwujudnya 3 pilar tujuan pembangunan ekonomi, yaitu pro-growth strategy (mewujudkan pertumbuhan ekonomi), pro-job strategy (penyerapan tenaga kerja) dan pro-poor strategy (pengentasan kemiskinan). Realisasi pencapaian tujuan tersebut ternyata masih sulit diwujudkan karena agroindustri perikanan tangkap skala kecil dan menengah masih mempunyai sejumlah permasalahan yang mengancam potensi keberlanjutannya pada masa mendatang antara lain, lemahnya daya saing, penguasaan teknologi, mutu produk, modal dan ketrampilan sumber daya manusia yang relatif masih rendah. Ancaman terhadap keberlanjutannya semakin serius karena pemanfaatan sumber daya perikanan tangkap bersifat terbuka sehingga mudah terdegradasi dari segi jumlah (stok) dan mengalami over fishing. Situasi tersebut menggambarkan bahwa keberlanjutan agroindustri perikanan tangkap merupakan sistem yang kompleks sehingga penilaiannya bukanlah hal yang sederhana dan mudah karena mencakup berbagai aspek yang sifatnya saling terkait dan dinamis. Hal ini memperkuat bahwa model prediksi keberlanjutan sangat dibutuhkan untuk mengetahui bagaimana keberlanjutan agroindustri perikanan tangkap pada masa mendatang sehingga langkah-langkah kebijakan peningkatan keberlanjutannya dapat diformulasikan secara tepat. Salah satu agroindustri perikanan tangkap yang menghadapi ancaman keberlanjutan adalah agroindustri teri nasi. Agroindustri teri nasi merupakan salah satu agroindustri perikanan tangkap yang pernah menjadi primadona di Indonesia. Hal ini ditandai dengan nilai ekspor produk teri nasi kering (chirimen) ke sejumlah negara, terutama Jepang, yang relatif tinggi. Akan tetapi volume ekspor dalam sepuluh tahun terakhir terus mengalami penurunan akibat keterbatasan bahan baku. Agroindustri teri nasi juga menghadapi persoalan lainnya diantaranya adalah kontinuitas bahan baku, mutu bahan baku, teknologi pengolahan, inovasi produk dan jaringan kerja dengan pelaku lainnya (partnership). Kondisi tersebut menunjukkan bahwa agroindustri teri nasi mempunyai permasalahan yang cukup kompleks sehingga berpotensi mengancam keberlanjutannya pada masa mendatang.

Abstrak: The objective of this research was to develop a decision support system for increasing Sustainable productivity on fishery agroindustry supply chain management that provides information and decision alternative to all stakeholders related to catch, effort, added value, agroindustry performance and sustainable fishery in Southeast Maluku District. Stock prediction model measure Value of CMsy and Emsy with equilibrium Schaefer as indicator of surplus production. Added value analysis model use to measure added value with profit margin. Agroindustry performance analysis model use to measure performance of Agroindustry with Balanced Scorecard (BSC) method, terperrate vision and company strategy into four different perspectives, financial, customer, internal Business process, and learning and growth. Sustainable model analysis with MDS method (Multidimensional Scaling). Stock prediction model showed that catch and effort in Southeast Maluku District still below sustainable maximum level. Added value analysis model the result showed that the added value is very low. Analysis agroindustry performance model there sult showed that financial perspective has greatest achievement performance index Sustainability model used to calculate the level of sustainability off isheries in South east Maluku District measured the dimensions of the three- dimensional ecological, social, and economic. MDS results showed that all the dimensions included in the category of less sustainable. The main conclusion of this research is provide information to the agroindustry fishery supply chain actors related catch and effort. added, agroindustry performance, and sustainability fishery in Southeast Maluku District.

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
