Judul: Pemanfaatan Reptil dan Amfibi di Kota Jakarta dan Bandung
Abstrak: Penelitian mengenai pemanfaatan satwa liar khususnya herpetofauna (amfibi dan reptil) sebagai obat masih sedikit dilakukan. Pulau Jawa yang mencakup 7% dari luasan Indonesia merupakan wilayah dengan total penduduk 150.4 juta jiwa atau 56.34% dari total pendududuk Indonesia. Oleh karena itu penelitian mengenai pemanfaatan herpetofauna sebagai obat di kota besar di Jawa dan aplikasi konservasi perlu dilakukan secara mendalam. tujuan penelitian ini adalah untuk mengetahui karakteristik pedagang dan konsumen obat yang berasal dari herpetofauna serta menelaah persepsi pedagang dan konsumen obat yang berasal dari herpetofauna dan pemanfaatannya sebagai obat.

Judul: Pemanfaatan Reptil Sebagai Obat dan Makanan di Daerah Khusus Ibu Kota (DKI) Jakarta
Abstrak: Economic crisis in Indonesia urge people to utilize natural resources including reptile. Reptile used to be regarded as adverse thing, now becoming profitable comodity for medicine and food. Nowadays, demand for reptile is increasing so that creates more risk for sustainability of reptile because most of reptile hunted from wild. The aim of this research was to know the characteristic of reptile traders and consumers, to know the utilization of reptile as medicine and food products and to investigate reptile trafficking in DKI Jakarta. This research was carried out from November until Desember 2008 in DKI Jakarta. The direct observation and interview to the traders and consumers were be used to collect data. There were ten traders selected by purposive sampling method. Whereas 30 consumers were selected based on the average of daily visitors. Most of traders were Indonesian male with average age of 43 years old and having selling experience for 2-43 years. Most of consumer were Indonesian male with the average of age 34 years old. Their education background were senior high school. There were 13 species (southern Indonesian spitting cobra, king cobra, reticulated python, copperhead racer, mangrove snake, banded krait, Malayan krait, ground pit viper, Indian rat snake, asian water monitor, tockay, skink and southest asian softshell turtle) of reptiles that be used as medicine product (fresh blood, salve, capsule, cream, oil, dried gall bladder, dried male genital and powder). There were 7 species (southern indonesian spitting cobra, reticulated python, crocodile, asian water monitor, tockay, skink and southest asian softshell turtle) were used for food products (roasted meat, soup, frieds meat and fried meat powder). Reptile trafficking in DKI Jakarta was divided into 2 networking system, which are: 1) small scale trader (wild reptiles- hunters - primary collectors - secondary collectors - small scale traders - consumer) and 2) large scale trader (wild reptiles - hunters - primary collectors – small scale productions - large scale traders - consumers). People usually utilize reptile for treating skin diseases. It is necessary to control reptile hunting in order to prevent those species from extinction. Breeding in captivity is on off alternatives to reduce hunting of reptile from the wild. Formal monitoring and regulation in reptile utilization by BKSDA DKI Jakarta, monitoring and contolling by BPOM DKI Jakarta as well as research on bioactive content in reptile meat

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
