Judul: Karakteristik Karkas dan Non Karkas Domba Ekor Tipis Berdasarkan Body Condition Score di TPH Maleber Bogor
Abstrak: Body condition score (BCS) is one indicator to know high or low of fat and meat deposit on carcass and non carcass from an animal. The purpose of the research to evaluated carcass and non carcass characteristic of thin-tailed sheep (DET) on Body condition score (BCS) effect at slaughter house Maleber, Bogor. Research used 99 heads of DET. The sheep grouped into 3 group BCS, thin (1), medium (2) and fat (3) . Data were analyzed by Analysis of Variance (ANOVA). The result showed DET with BCS 3 (fat) were significant different higher live weight, carcass weight, and empty body weight from the other BCS (thin and medium). Carcass’s percentage on BCS effect showed same value from efect value of BCS 1, 2, and 3 . The differences of body condition score effect to non carcass characteristic were significantly (P<0.01) on weight and diverse on percentage whereby on the percentage of liver and rumen is different (P<0.05) but peresentase other components except heart, spleen and skin very different (P<0.01) . The percentage of weight from spleen, skin, and blood is not effected by BCS.

Abstrak: A total of 119 local ewe which consist of 18, 76 and 25 garut sheep, thintailed sheep and fat-tailed sheep was used to evaluate the characteristics of carcass and non carcass at slaughterhouse in Maleber Bogor. The data were analyzed using Analysis of Covariance (ANCOVA), with slaughter weight as a covariable. The results showed that slaughter weight, carcass weight, empty body weight and carcass percentage among these breeds were no significantly different (P>0.05). There were no significantly differences among breeds in the weights of non carcass components, except kidney and shank. There were no significantly among breeds differences in percentage of non carcass components, except kidney percentage. In general, the garut sheep, thin-tailed and fat-tailed slaughtered at weight 20.46 kg, 15.73 kg and 15.98 kg had carcass percentages of 47.14%, 46.61% and 47.65%, and non carcass percentages of 33.56%, 32.73% and 33.32% respectively

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.
