Judul: Studi Kasus Komunitas Nelayan Sea Farming Pulau Panggang, Kelurahan Pulau Panggang, Kabupaten Administrasi Kepulauan Seribu Jakarta
Abstrak: Sea Farming as a program of empowerment that based on community development has its advantages for the community. The program focussed to fish culture of Epinephelus fuscoguttatus and it has successful descripted the empowerment grow process in fisheries community at Panggang Island. As the indicator of community empowerment, the community autonomus may based from Arnstein Participation Level (1969). The empowerment that based on community development requires that people have the capacity to define their own needs and to act to have them met. In this case, the community has successful to define their own needs in this fish culture, and they know how to solve that.

Judul: Pemberdayaan Komunitas Nelayan Melalui Program Pemberdayaan Ekonomi Masyarakat Pesisir (Studi Kasus Desa Labuan Kecamatan Lage Kabupaten Poso Provinsi Sulawesi Tengah)
Abstrak: Masyarakat pesisir, secara lebih khusus komunitas nelayan merupakan satu pelaku usaha di bidang perikanan yang sampai saat ini terkategorikan sebagai kaum miskin dan memiliki banyak persoalan, yang turut memperberat tekanan terhadap pemanfaatan sumberdaya pesisir. Kesemuanya diakibatkan oleh belum adanya konsep pembangunan masyarakat pesisir (nelayan) sebagai subyek dalam pemanfaatan sumberdaya pesisir. Program Pemberdayaan Ekonomi Masyarakat Pesisir (PEMP) merupakan salah satu program yang disusun untuk lebih memberdayakan masyarakat pesisir (nelayan). Program ini disusun dengan melihat kenyataan bahwa rata-rata tingkat pendidikan masyarakat pesisir relatif rendah sehingga kurnag memiliki pemahaman yang cukup dalam mengeksploitasi sumberdaya perikanan secara berkelanjutan; keterbatasan modal dan keterampilan termasuk sarana dan prasarana untuk memfasilitasi kegiatan pemanfaatan sumberdaya perikanan; sistem pengelolaan sumberdaya yang dilaksanakan secara individu atau bergantung kepada orang lain sehingga cenderung eksploitatif, dan pengelolaan pendapatan yang cenderung konsumtif.

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
