Judul: Analisa tahap awal dan usaha pemanggulan penurunan populasi ternak besar ruminasi
Abstrak: Penelitian ini dilakukan pada dua desa contoh di Wilayah Kecamatan Lemah Abang, Daerah Tingkat II Kabupaten Bekasi Jawa Barat, sejak pertengahan Bulan Februari 1985 sampai Bulan April 1985, kemudian dilanjutkan Bulan Desember 1986 sebagai survey keberhasilan Inseminasi Buatan (IB). Desa-desa tersebut adalah Desa Cibatu dan Desa Cipayung. Desa Cibatu merupakan daerah pertanian dengan usaha ternak kerja, daerah industri dan pemukiman manusia, sedikit terkena pengaruh tenaga kerja mekanis, serta terbatas daerahnya memperoleh air dari pengairan teknis Jatiluhur. Sedangkan Desa Cipayung merupakan daerah mekanisasi pertanian, industri dan pemukiman manusia serta sepenuhnya memperoleh air dari pengairan teknis Jatiluhur. Penelitian ini mempunyai latarbelakang tentang pengembangan pertanian sepanjang tali air pengairan teknis Jatiluhur, pengaruh era industri dan perluasan areal pemukiman manusia, para urban, pola penggunaan tenaga kerja biologis dan mekanis, serta terjadinya penurunan populasi ternak besar ruminansia di Wilayah IV Dinas Peternakan Daerah Tingkat I - Jawa Barat. Semua unsur tersebut saling mempengaruhi desa-desa penelitian. Penelitian ini bertujuan untuk mengetahui (1) Fak tor-faktor yang mempengaruhi perkembangan populasi ternak besar ruminansia, (2) peranan ternak sebagai sumber tenaga kerja, (3) teknologi tepat guna yang dapat mempengaruhi minat beternak petani, (4) prospek perkembangan ternak besar ruminansia, dan (5) sejalankah antara kebi jakan Pemerintahan Daerah (Pemda) dengan Sektor Peternakan setempat mengenai pembangunan sektoral dengan pengembangan Wilayah.

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
