Judul: The anoas bubalus depressicornis and Bubalus quarlesi as alternatives for domesticated animals in preventing their extinction
Abstrak: Anoa adalah salah satu satwa liar endemik di Sulawesi (Indonesia) dan dilindungi oleh Undang-undang No. 5 Tahun 1990, dan masuk kategori satwa liar yang rawan dan terancam punah (endungered). Penelitian ini bertujuan untuk mengetahui dan mempelajari sedikit tentang tingkah laku dan adaptasinya, baik terhadap karakteristik anoa dan pola penanganan, pemberian pakan dan tingkah lakunya, siklus reproduksi dan bihaviornya serta gambaran organ pencernaan, reproduksi serta gambaran perototan pada karkas anoa.

Judul: Pola reproduksi pada anoa (Bubalus (Anoa) sp.)
Abstrak: Tulisan ini bertujuan untuk mengetahui beberapa aspek biologi reproduksi dari anoa dalam hubungannya dengan pelestarian dan usaha pembudidayaannya. Anoa merupakan salah satu anggota Bovidae yang dima- sukkan kedalam genus Bubalus, dengan dua species, yaitu: Bubalus (Anoa) depressicornis dan Bubalus (Anoa) quarlesi. Anoa merupakan satwa langka yang hanya terdapat di Indone- sia pulau Sulawesi, umumnya hidup di hutan-hutan yang le- bat di dekat aliran sungai, danau, rawa-rawa, sumber air panas yang mengandung belerang dan sepanjang pantai. Anoa mempunyai sifat-sifat sebagai berikut: merupakan hewan herbivora, ruminansia, mammalia, hewan yang melindungi anaknya dengan ketat dan hewan yang mempunyai suhu tubuh yang tetap. Organ reproduksi jantan terdiri dari testes, epididy- mis, ductus deferens, uretra, penis dan dilengkapi dengan kelenjar vesikuler, prostata dan cowper. Organ kelamin betina terdiri dari ovarium, tuba fallopii, uterus, ser- viks, vagina, vulva dan klitoris. Anoa mencapai dewasa kelamin pada umur dua tahun, be- rahi pada anoa ditandai dengan tingkah laku betina yang sering menguaknguak dan bila diperiksa vulvanya akan ter- lihat adanya pembengkakan, kemerahan dan pengeluaran cair- an yang transfaran, anoa mempunyai siklus berahi selama satu setengah bulan. Didalam kegiatan reproduksi umumnya seekor pejantan hanya melayani seekor betina atau pasangannya. Secara ga- ris besar periode kopulasi pada anoa dapat dibagi dalam beberapa tahap, yaitu: percumbuan, penunggangan, intromisi dan ejakulasi. Kopulasi dilakukan dengan pejantan menung- gangi si betina. Kebuntingan pada anoa berlangsung selama 276 325 hari. Anoa untuk pertamakali melahirkan, umumnya pada umur tiga tahun, interval beranak selama dua tahun, anak yang dilahirkan akan disusui selama satu tahun dan umumnya melahirkan satu ekor anak setiap kelahiran atau monotocus…

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
