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.

Abstrak: The objectives of this research were to find out information on both body measurement and potencies of swamp buffalo at Cibadak subdistrict in Lebak District and Cisata subdistricts in Pandeglang Districts. Thi research was carried out from September to November, 2008. A total number of swamp buffloes observed were 220 hd both female and male of those from Cibadak and Cisata district were 79 hd and 141 hd respectively. Various body measurement observed were body length, round chest, chest depth, shoulder height and hip height. Mean and standar deviation of individual body measurement of swamp buffalo within location were calculated by descriptive analyses, while mean differences between two location were tested by t-test. The result showed that all body measurement of swamp buffalo in Cisata were very significantly higher (P<0,01) than those in Cibadak Subdistrict. Measurements of both shoulder height and hip height of male buffalo at the age of 1-3 mo in Cisata were significantly higher (P<0,05) than those in Cibadak. Measurements of round chest and chest depth of female buffalo at the ages of 12-15 mo and 2-3 yr in Cisata were higher (P<0,05) than those in Cibadak, while hip heights at the ages of 12-15 mo and >4 yr of female buffalo in Cisata were significantly higher (P<0,05) than those in Cibadak. Generally all body measurements of swamp buffalo, both male and female in Cisata Subdistrict were higher than those in Cibadak Subdistrict. This was supposed due to management feeding in Cisata better than in Cibadak.

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.
