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.

Abstrak: The objectives of the present study were to estimate variation of phenotypic characteristic, population structure and rearing management system of swamp buffalo from four sub-districts of Cibungbulang, Pamijahan, Nanggung and Sukajaya in Bogor district, West Java. A total of 238 swamp buffalo (101 males and 137 females) were used in this study buffalo were consisted of 54 heads swamp buffaloes from Cibungbulang (27 males and 27 females), 40 heads swamp buffaloes from Pamijahan (23 males and 17 females), 79 heads swamp buffaloes from Nanggung (29 males and 50 females) and 65 heads swamp buffaloes from Sukajaya (22 males and 43 females). Body dimension studied were wither height, hip height, hip width, body length, chest circumference, chest depth and chest width. Data obtained were analyzed by t test analysis with minitab package program version 14.0, while qualitative data were analyzed by descriptive analysis. The result showed that the body measurement of buffaloes which have age from 0-1 years almost the some in all districts observed. However, at the age 1 to 3 years in male observed in Pamijahan higher than Cibungbulang, Nanggung and Sukajaya (P<0,05). At the age up to 3 years in female observed in Cibungbulang higher than in Pamijahan, Sukajaya and Nanggung (P<0,05). The coat color of buffalo in Bogor district dominantly by dark gray (70,8%) followed light gray (27,4%) and albino (1,8%). Feet coat color dominantly by white color (76,2%) followed by gray color (13,7%) and black color (10,1%). The whorls almost found in head (86,3%), hip (79,2%), chest (72,1%) and under stomach (44,6%). Keywords : swamp buffaloes, quantitative characteristic, qualitative characteristic

Judul: Sintesis 1-Kloro-2-metoksi-6-propilnaftalena-1,3-dioksolana (1:1) sebagai Prekursor Asam (S)-(+)-(6-Metoksi-2-naftil)propanoat
Abstrak: Senyawa 1-kloro-2-metoksi-6-propilnaftalena-1,3-dioksolana (1:1) sebagai prekursor asam (S)-(+)-(6-metoksi-2-naftil)propanoat disintesis dari bahan awal 2-metoksinaftalena. Tahapan sintesis diawali dengan klorinasi menggunakan 2 jenis pereaksi klorinasi, yakni isosianurat terklorinasi dan NaOCl. Klorinasi dengan isosianurat terklorinasi berhasil menyintesis 1-kloro-2-metoksinaftalena sebagai produk monoklorinasi melalui pencirian dengan kromatograf gas-spektrometer massa (GC-MS). Nisbah konversi produk paling efisien diperoleh pada laju penambahan 2.5 mmol/jam. Sebaliknya, klorinasi dengan NaOCl menghasilkan produk triklorinasi. 1-Kloro-2-metoksinaftalena selanjutnya diasilasi dengan propanoil klorida, tetapi analisis dengan GC menunjukkan bahwa produk asilasi tidak terbentuk. Sistem bebas-air diperlukan untuk keberhasilan proses asilasi tersebut.
