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: Keanekaragaman Jenis dan Nilai Ekonomi Satwa Liar yang Digunakan Sebagai Obat di Jawa Tengah
Abstrak: Indonesia has high biodiversity and endemism, however extinction rate is also high. Excessive harvesting and habitat destruction by human activity were the dominant factor leading to species extinction and biodiversity loss. Most of the people depend on biodiversity as foods, medicine and housing, but sometime they heedless sustainable utilization. This research was aimed to identify wild animal diversity utilized as traditional medicine and its economics value in Central Java. Research was carried out from May to August 2007 in Central Java Province. Information was obtained through semi structured questionnaires applied to 105 respondents from 19 sub-provinces. I recorded 54 animal species utilized in traditional medicine, 42 of which are wild animal species (vertebrates), 10 avertebrates and 2 livestock animals; whose products were recommended for the treatment of 50 types of illnesses. The most frequently quoted treatments were for respiratory system (20 species), skin disease (18 species) and increasing stamina and appetite (14 species). Reptiles (21 species), followed by mammals (11 species) and fishes (4 species) represented the bulk of medicinal species. Medicinal wild animal is not only used for local consumption, but also exported. The economic value of wild animal to human health in Central Java is estimated to reach Rp.1,421,714,004 per year. Excessive harvesting of medicinal wild animal might increase species loss which resulted in extinction. However, if harvest and trade are based on sustainable utilization, it will not only increasing economic benefit but also generate effort for conservation.

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
