Judul: Alternatif kebijakan pemberdayaan masyarakat nelayan berwawasan lingkungan di Muara Angke, Jakarta Utara:
Abstrak: Di wilayah Muara Angke, kehidupan sosial masyarakat nelayan tidak berbeda jauh dengan kehidupan sosial masyarakat nelayan lainnya yang ada di Indonesia. Kondisi kehidupan nelayan paling parah, dialami pada waktu musim barat daya dan musim timur. Biasanya pada musim barat daya, angin bertiup dari arah barat daya ke arah timur laut melewati pulau-pulau dengan kecepatan yang sangat kencang (badai), sedangkan pada musim timur, angin bertiup kencang mulai pagi hingga malam hari dengan iringan badai dan gelombang laut yang besar, sehingga menyulitkan nelayan untuk melakukan kegiatan di laut. Selain itu buruknya kualitas lingkungan akibat pencemaran yang terjadi di perairan Teluk Jakarta telah menimbulkan kerugian yang serius pada kehidupan ekologis, ekonomi, kesehatan, maupun estetika. Dampak perubahan musim barat dan timur serta pencemaran kualitas air mengakibatkan nelayan memanfaatkan sumberdaya alam lainnya yang ada di sekitarnya yaitu, menebang pohon mangrove di Kawasan Suaka Margasatwa Muara Angke untuk dijadikan bahan baku arang sebagai profesi baru atau tambahan penghasilan. Oleh karena itu perlu dilaksanakan pemberdayaan masyarakat berwawasan lingkungan. Agar pemberdayaan tepat maka penting untuk dilakukan kajian alternatif kebijakan pemberdayaan masyarakat berwawasan lingkungan.

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
