Judul: Study of Rent Seeking and Corruption in Capture Fisheries
Abstrak: Perilaku perburuan rente dan korupsi memberi dampak juga pada kinerja pembangunan diberbagai sektor termasuk di perikanan tangkap. Tujuan penelitian ini adalah mengungkap dan menganalisis perburuan rente dan korupsi, serta menghitung kebocoran ekonomi di sektor perikanan tangkap, serta mengukur tingkat inefisiensi serta perkembangan pelabuhan perikanan secara makro. Metode yang digunakan penelitian campuran yang mengkombinasikan penelitian kuantitatif dan kualitatif. Hasil penelitian menemukan dua model bahwa perburuan rente dan korupsi pada perikanan tangkap memiliki hubungan erat secara signifikan, kebocoran ekonomi mencapai rata-rata 44,05 persen dengan ICOR rata-rata 5,45, dan pelabuhan perikanan belum menjadi pusat perdagangan ikan dan pengembangan industri perikanan., Rent-seeking behavior and corruption have an impact on development performance in various sectors including capture fisheries. The purpose of this research is to reveal and analyze rent-seeking and corruption, as well as calculate economic leakage in the capture fisheries sector, and measure the level of inefficiency and the development of fishing ports at a macro level. The method used is mixed research that combines quantitative and qualitative research. The results found two models that rent-seeking and corruption in capture fisheries have a significantly close relationship, economic leakage reaches an average of 44.05 percent with an average ICOR of 5.45, and fishing ports have not become the center of fish trade and fishing industry development.

Judul: Analisis Kebijakan Perikanan Tangkap terhadap Nelayan Kota Semarang: Perspektif Ekonomi Politik
Abstrak: The orientation of development on the fisheries sector is increasing national production through the modernization with a capitalization that it would open the risks of poverty for the fishermen. This research aims to analyse capture fisheries policy of Semarang City and its impact on fishermen and identify whether or not the symptoms of compradorization of capture fisheries in Semarang City. This research method used qualitative and quantitative approaches using primary and secondary data. The quantitative approach using analysis of unequal distribution income, while a qualitative approach using indepth interview with analysis of political economy and analysis of compradorization symptoms. The result of this research shows that there are disparities in the distribution income of respondents in the average category due to policies that did not extend to the fisherman community. Compradorization symptoms are found on the capital inflow of marketing system with the Department of Marine and Fisheries of Semarang City as the comprador class.

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
