Judul: Fenomena Perburuan Rente dan Tindakan Korupsi di Provinsi DKI Jakarta Periode 2012-2017
Abstrak: Fenomena korupsi dan aktivitas ekonomi perburuan rente merupakan permasalahan lama yang dihadapi oleh negara-negara di seluruh dunia yang dapat mengakibatkan tidak maksimalnya pelaksanaan program pembangunan. Provinsi DKI Jakarta merupakan wilayah yang dimana menjadi pusat pemerintahan, pusat ekonomi, serta ibukota dari Indonesia. Oleh karena itu, meneliti fenomena korupsi dan aktivitas ekonomi perburuan rente yang ada di Provinsi DKI Jakarta menjadi hal yang menarik. Metode yang digunakan dalam penelitian ini adalah analisis data secara kuantitatif dan metode deskriptif kualitatif dengan menggunakan data dari hasil wawancara mendalam serta studi kepustakaan. Hasil dari penelitian ini memperlihatkan bahwa terdapat banyak fenomena korupsi dan aktivitas ekonomi perburuan rente yang terjadi di Provinsi DKI Jakarta. Sektor yang paling dominan adanya fenomena korupsi dan aktivitas perburuan rente antara lain pekerjaan fisik untuk bidang pendidikan, kesehatan, transportasi, dan pekerjaan umum. Maka dari itu harus ada kerjasama antara pihak pemerintah, penegak hukum, dan masyarakat di Provinsi DKI Jakarta untuk menghadapi fenomena aktivitas ekonomi perburuan rente dan korupsi tersebut.

Judul: Fenomena Perburuan Rente dan Korupsi di Kabupaten Kuningan, Jawa Barat, Sebelum dan Setelah Otonomi Daerah (Periode 1998 – 2012)
Abstrak: Rent seeking economy activity and corruption are problems that usually occur in developing countries. Rent seeking economy activity and corruption will impact on national budget that is allocated for society prosperous. Kuningan regency is a part of area in Indonesia as a developing country. Because of that, it becomes interesting to examine about rent seeking economy activity and corruption that occur in Kuningan regency. This research uses time range between 1998-2012 that compare the condition before and after autonomy. The methodology that is used in this research is data analytical and indepth interview that is presented in the descriptive qualitative methodology. The result of this research present that there are many cases of rent seeking economy activity and corruption occur in Kuningan regency. Rent seeking activity and corruption are occurred in procurement sector. There is difference pattern in the rent seeking economy activity, that use family relationship pattern before autonomy and reciprocate pattern after autonomy. Base on Indonesia‟s law, there are three kinds of corruption that usually occur in Kuningan regency. Because of that, it has to be a cooperation between government, institution that has competent in law, and society in Kuningan regency to solve rent seeking economy activity and corruption problems.

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
