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: The purpose of the research was to evaluate the characteristics of carcass and non carcass of thin-tailed sheep (DET) on different live weight in TPH Maleber, West Java. Research used 56 heads of DET ewes. The sheep grouped into live weights at 10 kg, 20 kg and 30 kg. Data were analyzed by Analysis of Variance (ANOVA). The result of the research showed that the differences of live weight were significantly (P<0.01) influenced on empty body weight and carcass weight. DET that were slaughtered at 30 kg was heavier on carcass percentage compared to 20 kg. The average percentage of carcass at live weight 10 kg, 20 kg and 30 kg was 46.09%, 42.87% and 49.56% respectively. Non carcass components of DET were slaughtered at 30 kg was significant (P<0.01) heavier than live weight of 20 and 10 kg. The percentage of edible portion of non carcass was of 42%-48% of empty body weight.

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.
