Judul: Phenotypic characteristic and production system of buffalo (Bubalus bubalis) as a basis for the development of a village breeding program in Banten
Abstrak: Keberadaan kerbau rawa di Provinsi Banten sedemikian rupa telah menyatu dengan kondisi sosial dan budaya masyarakat setempat. Perannya dalam kehidupan sehari-hari adalah sebagai ternak kerja untuk membajak sawah, sumber daging dan tabungan. Mengingat peran kerbau rawa bagi kehidupan peternak di Provinsi Banten sangat penting, maka diperlukan upaya-upaya peningkatan dan pelestarian kerbau yang berkelanjutan. Penelitian ini dilakukan untuk mengetahui keragaman fenotipe melalui analisis morfometrik, mempelajari pengetahuan, motivasi dan partisipasi peternak dalam kegiatan pemuliaan kerbau, dan menyusun pola pemuliaan kerbau pada peternakan rakyat di Banten. Metode penelitian yang digunakan adalah survey. Penentuan sampel berdasarkan purposive sampling sehingga penelitian ini dilakukan di Kabupaten Serang, Pandeglang dan Lebak. Materi penelitian yang digunakan adalah 300 ekor kebau rawa dewasa dan 60 orang responden peternak kerbau di Kabupaten Serang, Pandeglang serta Lebak Provinsi Banten. Data yang dihimpun merupakan data primer. Data sekunder terdiri atas 100 ekor kerbau rawa Aceh Besar, 99 ekor kerbau Hulu Sungai Selatan, 50 ekor kerbau Pleihari, 39 ekor kerbau Dompu, 40 ekor kerbau Hu’u, 40 ekor kerbau Kempo, 40 ekor kerbau Pajo, dan 40 ekor kerbau Woja. Data sekunder berasal dari data penelitian peneliti pada kerjasama kemitraan penelitian pertanian dengan perguruan tinggi (KKP3T) pada tahun 2007, digunakan pada penentuan jarak genetik antarpopulasi kerbau rawa Indonesia.

Judul: Karakteristik Produksi dan Potensi Pengembangan Kerbau Rawa pada Daerah Basah dan Kering di Kabupaten Bima
Abstrak: The purpose of this research was to study the characteristics and potential production of swamp buffalo in wet and dry areas of Bima regency. The study used survey and direct observation methods on the targeted areas. The primary and secondary data were collected and analyzed descriptively. The buffaloes in Belo district were semi-intensively reared, whereas those in Wera district were extensively reared. The buffalo in Belo district had sex ratio, age of first mating, age of first parturition, calving rate, calf crop, calf mortality, periode of first mating after calving, and calving interval were 1:3, 3.4 years, 4.2 years, 91.1%, 76.2%, 12%, 2.4 months, 15.9 months respectively. Meanwhile, the reproductive characteristics in Wera district were 1:3, 3.3 years, 4.1 years, 84.2%, 70.3%, 17.1%, 2.3 months 14.4 months respectively. The buffaloes in Belo had BCS 2 (35%), BCS 3 (60%), and BCS 4 (5%), whereas in Wera have BCS 2 (45%), BCS 3 (50%) and BCS 4 (5%). In general, the buffaloes In Belo had better performance compared to that in Wera district. However, the potential land and feed resources for development of buffalo in Wera district still high compared with Belo district.

Judul: Elektrodeposisi Film Tipis Semikonduktor Cu2ZnSnS4 (CZTS) pada Substrat Kaca ITO
Abstrak: Semiconductor Cu2ZnSnS4 (CZTS) thin film that can be used as absorber layers on solar cell module was made via electrodeposition method. CZTS thin film was electrodeposited on the surface of a silicate glass coated with a thin layer of indium tin oxide (ITO). Deposition process was done using potentiostatic mode at room temperature with a potential of 1.05 V for 30, 45, and 60 minutes, followed with annealing the film at 2 different temperatures, 500 ºC using furnace and 180 ºC using hot plate, both treatments for 45 minutes in N2/H2S atmosphere. The X-ray difractograms were analyzed using Match 2 program and showed that the CZTS thin films had kesterit crystalline structure, with a low percentage of CZTS phase. The thin film also contained secondary phases such as Cu2S, ZnS, and SnS. The obtained CZTS thin films had a thickness between 1.039 and 1.676 μm. Absorption study showed that the band gap energy of CZTS thin films which was annealed using furnace ranged from 1.50 to 1.52 eV, whereas that annealed using the hot plate was not observed. The band gap energy value showed that CZTS thin films can be used as sunlight absorber layers on solar cell. The formation of CZTS crystal film on this investigation was effectively performed using furnace annealing process at a temperature of 500 ºC with deposition time of 45 minutes.
