Judul: Infeksi Cacing Saluran Pencernaan Pada Anoa Dataran Rendah (Bubalus depressicornis) Di Taman Margasatwa Ragunan Jakarta.
Abstrak: Anoa dataran rendah (Bubalus depressicornis) merupakan satwa endemik Sulawesi, dengan status terancam punah. Konservasi ex-situ merupakan salah satu cara pelestarian anoa dataran rendah. Infeksi cacing saluran pencernaan merupakan masalah yang sering ditemukan dalam upaya konservasi. Penelitian ini bertujuan untuk mengetahui jenis dan derajat infeksi cacing saluran pencernaan pada anoa dataran rendah di Taman Margasatwa Ragunan. Sampel tinja anoa diperiksa menggunakan metode modifikasi McMaster, flotasi sederhana serta filtrasi dan sedimentasi. Hasil penelitian menunjukkan seluruh sampel tinja anoa dataran rendah terinfeksi cacing nematoda saluran pencernaan dengan derajat infeksi rendah. Cacing nematoda yang di temukan adalah cacing strongyle dan Strongyloides. Hasil identifikasi larva infektif strongyle adalah Trichostrongylus spp., Haemonchus contortus, dan Cooperia curtecei.

Judul: Infestation of Ectoparasite Flies (Diptera:  Cyclorrapha) on Lowland Anoa (Bubalus depressicornis) in Ragunan Zoological  Park, South Jakarta
Abstrak: Anoa dataran rendah (Bubalus depressicornis) merupakan salah satu hewan yang terancam punah. Anoa di Taman Margasatwa Ragunan, Jakarta Selatan dipelihara secara intensif. Sistem ini memudahkan pemantauan kesehatan hewan. Lalat merupakan salah satu penyebab gangguan kesehatan pada anoa. Lalat merupakan salah satu jenis ektoparasit yang dapat mengganggu kenyamanan hidup hewan. Penelitian ini bertujuan untuk mengetahui keberadaan dan jumlah lalat ektoparasit serta faktor-faktor yang berhubungan dengan jumlah lalat pada anoa dataran rendah di Taman Margasatwa Ragunan Jakarta Selatan. Penelitian dilakukan pada dua ekor anoa dataran rendah jantan pada tiga kali pengamatan, yaitu pada pagi hari (08.00-09.00), siang hari (12.00-13.00), dan sore hari (16.00- 17.00). Pengamatan lalat meliputi penghitungan dan identifikasi lalat secara makroskopis pada dua anoa dan daerah penghitungan menggunakan binokular dalam tiga kali pengamatan (pagi, siang, dan sore) karena pihak pengelola Taman Margasatwa Ragunan tidak mengizinkan menyentuh atau mengganggu fisik anoa. Penangkapan lalat dengan menggunakan flies trap dilakukan untuk verifikasi famili lalat dan pengambilan gambar lalat. Pada saat yang sama juga diamati apakah anoa yang sedang berteduh atau berendam. Hasil penelitian menunjukkan bahwa infestasi lalat pada dua anoa dataran rendah di Taman Margasatwa Ragunan termasuk dalam kategori rendah dan aktivitas berendam dapat menurunkan jumlah infestasi lalat pada anoa dataran rendah.

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
