Judul: Studi ukuran tubuh kerbau (Bubalus bubalis) di beberapa wilayah di kabupaten Lebak, provinsi Banten
Abstrak: The huge number of buffalo population in Lebak district, province of Banten is promizing to be developed, especially to support meat sustainability program Buffalo in Lebak district produce 85,5% of meat. Buffalo also important as source of draught power and manure as fertilizer. Unfortunally, this potential animal has not been utilized optimally. Limited information about characteristics and management of nourhising contribute to the condition. This study was conducted in order to fill the need of that information.

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: Sintesis Krisin dari Floroglusinol
Abstrak: Flavone is a class of flavonoid, widely distributed in vascular plants. Flavones containing hydroxyl groups at 5 and 7 position are quite important regarding their biological activities and their abiquity in nature. Flavone having hydroxyl groups only at position 5 and 7 or 5,7-dihydroxyflavone is known as chrysin. In this study, crude chrysin had been successfully synthesized in 3 steps from phloroglucinol as starting material. Phloroglucinol was acetylated with acetonitrile and HCl gas, resulting phloroacetophenone amount to 74%. Phloroacetophenone benzoylation with 4.5 equivalents of benzoyl chloride produced tribenzoyl phloroacetophenone in 103–107% of yield and the subsequent Baker-Venkataraman rearrangement of the ester by using KOH in dried pyridine produced crude chrysin, with conversion percentage of 71.62%. All synthetic products had been characterized by melting point and spectroscopically.
