Judul: The effect of shearing wool on sheep's behavior
Abstrak: Sheep are homeotherms or warm-blooded animals that can maintain their body temperature in a safe range, known as the thermoneutral zone, without making any impacts on their bodies. Environmental and genetic factors could affect the productivity of sheep, but the most influential is environmental factors. Temperature and humidity are some environmental factors that have a direct impact on animals. The purpose of this study is to analyze the effect of shearing wool on sheep's behavior. Ten sheep are classified into 2 treatment groups, shorn sheep (P) and unshorn sheep (TP) will be observed in the field laboratory of small ruminants, Faculty of Animal Science, IPB University for thirty days from February until March 2021. The results of this research show the effect of shearing was significant (P<0,05) on ingestive, drinking, agonistic, eliminative, resting, sleeping, caregiving, locomotion, standing and rumination behavior., Domba merupakan hewan homeoterm atau hewan berdarah panas yang mampu mempertahankan suhu tubuhnya pada kisaran tertentu, yang disebut zona termoneutral, tanpa menimbulkan dampak apa pun pada tubuhnya. Faktor lingkungan dan genetik dapat mempengaruhi produktivitas domba, namun faktor yang paling berpengaruh adalah faktor lingkungan. Penelitian ini bertujuan mengevaluasi pengaruh pencukuran wol terhadap tingkah laku domba. Penelitian ini menggunakan 10 ekor domba yang dibagi menjadi 2 perlakuan yaitu domba yang dilakukan pencukuran (P) dan domba tanpa pencukuran (TP) di Laboratorium Lapang Ruminansia Kecil, Fakultas Peternakan, IPB University dari Bulan Februari sampai Maret 2021. Hasil analisis menunjukkan bahwa pencukuran wol pada domba berpengaruh nyata (P<0,5) terhadap tingkah laku ingestive, minum, agonistic, eliminative, berbaring, tidur caregiving, locomotion, berdiri dan ruminasi

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.
