Judul: Behavior and Physiological Response of Local Sheep  during Shepherding in Semi Intensive Raising System
Abstrak: Domba memiliki tingkah laku yang berbeda untuk setiap rumpun. Penelitian ini bertujuan untuk mengevaluasi perbedaan respon fisiologi dan tingkah laku dari domba ekor tipis dan domba silangan garut yang dipelihara dengan sistem semi intensif. Penelitian ini menggunakan tujuh ekor domba ekor tipis dan enam ekor domba silangan garut dengan berat rata-rata 14,42±7,12 kg. Tingkah laku dan respon fisiologi diamati kemudian dianalisis dengan uji-T 5%. Hasil penelitian menunjukan persentase domba ekor tipis melakukan tingkah laku ingestive sebesar 90,57±1,20%, tingkah laku lokomosi sebesar 6,38±0,57%, tingkah laku panting sebesar 2,99±0,81±, dan tingkah laku resting sebesar 0,06±0,05%, sedangkan persentase domba silangan garut menunjukkan tingkah laku ingestive sebesar 90,77±1,20%, tingkah laku lokomosi sebesar 6,39±0,52%, tingkah laku panting sebesar 2,82±0,91%, dan tingkah laku resting sebesar 0,01±0,03%. Hasil penelitian menunjukan tingkah laku ingestive, browsing, grazing, lokomosi panting, dan resting domba ekor tipis dan domba silangan garut adalah sama. Respon fisiolgi detak suhu rektal, detak jantung dan laju respirasi domba ekor tipis dan domba silangan garut setelah penggembalaan tidak berbeda nyata. Dapat disimpulkan bahwa tingkah laku dan respon fisiologi domba ekor tipis dengan domba silangan garut yang dipelihara secara semi intensif adalah sama.

Judul: Respon fisiologis domba garut yang dipelihara secara semi intensif dengan perlakuan pencukuran di peternakan PT Indocement
Abstrak: The study was conducted to identify physiological response of garut sheep in different treatments (shearing and not shearing) and sex (male and female) in semi intensive system. The experiment was carried out at the PT Indocement Farm in Citereup district of Bogor regency, West Java. Design of this experiment was completely randomized design factorial with factor A was shearing, and factor B was sex. The parameters observed included body temperature, heartbeat, respiration rate and blood profile. The result showed that shearing significantly (P<0,01) effect on body temperature in the morning. Body temperature of shearing sheep (37.97±0.28 0C) was lower than not shearing (38.47±0.310C). In the afternoon showed that shearing significant (P<0.05) effect on body temperature. Body temperature of shearing sheep (38.45±0.20 0C) was lower than not shearing (38.70±0.25 0C). Heartbeat of male (86.72±6.47 rate/min) was significant higher than female (81.24±4.12 rate/min) in the evening. Respiration rate of male (24.08±2.78 rate/min) was significantly lower than female (28.16±2.20 rate/min) in the morning. For shearing sheep was lower than not shearing in the morning and afternoon. In the evening both male and female sheep that are not shearing was not significant, but significant with respiration of male sheared and female sheared. Stress indicated in male sheep and proved from neutrophils/lymphocytes ratio (0.88±0.36). Conclusion of this experiment showed that shearing, sex and time effected to the physiological response.

Judul: Sintesis Flavonol melalui 2’-Hidroksikalkon
Abstrak: Flavonol is a class of flavonoids commonly found in fruits and vegetables. Flavonol is very useful, especially in food sector and health. In this study, flavonol unsubstituted was successfully synthesized from an intermediate material 2’-hydroxychalcone. The 2’-hydroxychalcone was synthesized by Claisen-Schmidt condensation method between o-hydroxyacetophenone and benzaldehyde using 4 different catalysts, namely KOH 60%, solid pellet of KOH-grinding technique, BF3-Et2O, and NaH in DMF. The KOH 60% was the best catalyst, giving the highest yield (57%). Afterward, the flavonol was synthesized in 1-stage oxidation cyclization of o-hydroxyacetophenone using Algar-Flynn-Oyamada (AFO) reaction, giving 76%. The flavonol total yield from 2’-hydroxychalcone was 43%. All synthesized products were characterized by their melting points and their spectra. The success of the synthesis flavonol opens the way to synthesis of useful flavonol derivatives such as quercetin and kaempferol
