Judul: Respon Fisiologis dan Tingkah Laku Domba Ekor Tipis dengan Waktu Pemberian Pakan yang Berbeda
Abstrak: This study aimed to examine the relationship of feeding time on physiological response and the effect of feeding time on behavior of Javanesse thin tailed sheep. The composition of feed was 70% of concentrate + 30% of grass. The treatment in this study is the feeding time in the morning and evening. Parameters of physiological response that had been observed were heart rate, respiration rate, rectal temperature. Whilethe observed behavior were locomotive, ingestive and resting. This research was designed by completely randomized design with 2 treatments of feeding time with 6 replications for each of it. Data processed by ANOVA. The behavior data was analyzed by student’s test. The result showed that physiological responses of Javanese Thin Tailed Sheep were normal. Locomotive behavior of sheeps by feeding treatment in the morning was higher in the daytime. Ingestive behavior of sheeps by feeding treatment in the morning and afternoon completely reversed. Resting behavior was more frequently in the night in both paramaters.

Judul: Respon Fisiologis dan Tingkah Laku Domba Garut Jantan dengan Pakan dan Manajemen Pemberian Pakan Berbeda
Abstrak: Improving feeding and managament for sheep it is normally because of improving their performance. Thereby it can be effected to their physiological response and behaviour. This research aimed to compare physiological response and behaviour of garut rams with feed and different management feeding. This research used 16 garut rams (I0) with 2 factors and 4 replicates. First factors is type of feed R1 (40 % grass + 60% concentrate 1) dan R2 (40% mung bean sprout waste + 60% concentrate 2) and the second factors is management feeding in the morning (P) and management feeding in the afternoon (S). Physiological response were observed such as respiration, heart rate, and rectal temperatures. Behaviour were observed such as ingestive behaviour, licking and biteing other goods, resting, eliminasi, vokalisasi, and agonistic. Physiological response and behaviour data were analyzed by analysis of variance (ANOVA). The result shows that heart rate effected by feed. Sheep which is given feeding mung bean sprout waste have a higher value on heart rate (P<0.01). Rectal temperature efected by feed and management. Sheep which is given feeding mung bean sprout waste (P<0.01) and management feeding in the afternoon (P<0.05) have a higher value on rectal temperatures. Management feeding factors in morning of measuring ingestive behaviour have a higher value (P<0.05) but for resting behaviour, management feeding factors in the afternoon have a higher value (P<0.01). The grass have a higher value for eliminative in daylight periode (P<0.05). Both of factors were not significantly different (P>0.05) for measuring all of behaviour garut rams in the allnight periode.

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.
