Judul: Gerakan Paguyuban Petani Versus Negara dan Dampaknya Pada Tingkat Kesejahteraan Masyarakat Desa Sukamulya
Abstrak: Agrarian conflict occurs because of the different of interest between two or more actor to an agrarian source. Agrarian conflict which happen in Desa Sukamulya occurs because of the disagreement between the community and the representative of the state, Lanud Atang Sandjaya TNI-AU. Lanud Atang Sandjaya claims and take over the community’s land and make them have to fight back through the Paguyuban Petani movement. This movement’s goal is to return the land rights to the community. There are some factors that can make the Paguyuban Petani become a national issue; the leadership, the collectivism, and the activities of the Paguyuban Petani, and the support from other people. This research is to examine the relationship between the Paguyuban Petani’s level of success and the community’s welfare, either in economic or social. The result shows that Paguyuban Petani has a very weak relationship with the community’s economic welfare, but it has a strong enough relationship with the community’s social welfare in Sukamulya Village.

Judul: Perubahan Struktur Agraria dan Implikasinya terhadap Gerakan Petani Pedesaan (Analisa Karakter Forum Paguyuban Petani Jasinga Pasca PPAN)
Abstrak: Masyarakat Desa Curug dan Desa Tegal Wangi mengalami kerugian pasca hilangnya lahan garapan. Kerugian yang dialami berupa pengurangan luas penguasaan lahan dan perubahan tingkat pendapatan. Respon yang dilakukan oleh masyarakat di dua desa tersebut adalah dengan membentuk organisasi Forum Paguyuban Petani Jasinga. Tujuan penelitian ini adalah untuk menganalisis perubahan struktur agraria dan pengaruhnya terhadap karakter gerakan petani. Hasil penelitian menunjukkan tidak terdapat pengaruh antara perubahan status sosial ekonomi terhadap dimensi gerakan petani. Di sisi lain, dimensi gerakan petani memberikan pengaruh terhadap karakter gerakan petani.

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
