Judul: Kejadian Diare pada Kelompok Sosial di Penangkaran Monyet Ekor Panjang (Macaca fascicularis) di Jawa Barat.
Abstrak: Monyet ekor panjang merupakan satwa primata Indonesia yang sering digunakan sebagai hewan laboratorium atau hewan model untuk penelitian biomedis. Salah satu masalah klasik yang sering dihadapi pada penangkaran monyet adalah munculnya kejadian diare. Tujuan dari penelitian ini adalah mengetahui kejadian diare pada kelompok sosial di penangkaran monyet di Jawa Barat berdasarkan ukuran kelompok, mobilitas satwa, serta profil tingkah laku sosial. Kejadian diare pada populasi monyet per kandang diamati dengan adanya keberadaan feses diare feses lembek dan berair. Pengamatan tingkah laku sosial monyet ekor panjang dilakukan dengan menggunakan metode scan sampling selama 60 menit dengan interval setiap 1 menit per kandang. Hasil pengamatan kejadian diare menunjukkan terdapat kecenderungan rasio kejadian diare semakin tinggi terjadi pada kelompok dengan ukuran kelompok sosial (jumlah individu dalam kandang) terbesar dan mobilitas satwa tersering. Rata-rata persentase frekuensi tingkah laku agresif dan afiliatif paling tinggi muncul pada kandang dengan jumlah individu terbanyak dan mobilitas satwa terkompleks. Berdasarkan hasil penelitian dapat disimpulkan bahwa kejadian diare tertinggi terjadi pada kandang dengan ukuran kelompok terbesar, mobilitas satwa tersering, dan tingkah laku yang paling sering muncul pada kelompok tersebut adalah tingkah laku agresif dan afiliatif. Tingkah laku agresif dan afiliatif dapat memungkinkan meningkatnya stresor bagi individu subordinate dan penyebaran agen penyebab diare pada kandang terpadat menjadi lebih mudah.

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
