Abstrak: Conservation medicine is an emerging discipline that links to human and animal health, ecosytem health, and global environmental change. Recently, Javan Slow Loris is an endemic primates which is continuously hunted, which lead to decline of its population in its natural habitat. The goal of this research is to study the gastrointestinal helminths infection of Javan Slow Loris and infection intensity from pooled fecal samples in diagnostic laboratory of International Animal Rescue Indonesia from February-May 2014. Eleven pooled fecal samples from different cages are collected for 6 times were used. Samples were examined using the modified McMaster, flotation, and the modified sedimentation techniques was used to determine the intensity of helminth infections among the cages.Numerous well preserved eggs were examined from the point of view of morphology. Our result showed that all of cages were infected by two types of helminths: cestode and nematode including Hymenolepis sp., Ascaris, Strongyloides, and Strongylid.

Abstrak: Javan leopard (Panthera pardus melas Cuvier, 1809) is an endemic species of Indonesia that can only be found in Java island. This species is stated as critically endangered, so that the conservation act is needed to save Javan leopard. The objective of this research is to identify and determine the infection and the intensity of the gastrointestinal helminths in Javan leopard from Pusat Penyelamatan Satwa Cikananga (PPSC) and Situgunung Park, Taman Nasional Gunung Gede Pangrango (TNGGP). Four individual stool samples were collected from PPSC on Januari-Februari 2014 and 3 stool samples were collected from Situgunung Park, TNGGP on May 2013 and March-June 2014. All samples were examined using modified McMaster, flotation, and modified sedimentation techniques. The result showed that all samples were infected by gastro-intestine helminths. The identified helminths were strongylids (85,71%), trichurid and ascarids (57,14%) and Strongyloides (28,57%). The range of eggs per gram (EPG) varied from <50-8825 EPG. The highest count were found in strongylid (<50- 8825 EPG) in PPSC, followed by trichurid (<50-3750 EPG) in PPSC and Strongyloides (700-1100 EPG) in SGP. The lowest count was ascarid (<50 EPG) which was found in PPSC and SGP.

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
