Judul: Karakter Dominansi dan Perilaku Stereotipe pada Monyet Ekor Panjang (Macaca fascicularis) Sitaan serta Saran-saran Pengelolaannya.
Abstrak: This study is dedicated to support the behavioural management of confiscated dancing monkeys of cynomolgus macaques (Macaca fascicularis) at UPT Pusat Pelayanan Kesehatan Hewan Jakarta province. This management is to improve animal welfare and rehabilitate stereotypical anomaly behaviour. Therefore cages condition and behaviour of 47 confiscated monkeys were observed using instantaneous sampling method. The cages condition include 4 socially stable cages and 2 socially unstable cages. Dominant characteristic is found in both type of cages where at socially unstable cages shows higher frequency of aggressive behaviour. The stereotypical behaviour movement of head left to right (weaving) only found in socially unstable cage. Movement of head front to back (rocking) found in both cages and self-injurious behaviour (SIB) found in socially stable cages. In managing the dynamics and rehabilitate the abnormal behaviour mentioned above, it is found that environmental enrichment is needed. This includes social enrichment, occupational enrichment, physical enrichment, sensory enrichment, and nutrition enrichment. It is hope that these information will be the guideline in managing dominant character of confiscated monkeys and its stereotypical behaviour.

Abstrak: This study was dedicated to the development of the use and conservation policy of confiscated long-tailed macaques (Macaca fascicularis, cynomulgus macaques) in Jakarta Province. The macaques that have proven healthy physically and mentally will be returned to their natural habitat. However there were no behavioral assessments data and alternatives to utilize these mentally unhealthy macaques. For this purpose, we constructed behavioral assessments and explored the alternatives of animal use in scientific purposes. Among the 47 macaques observed using instantaneous or scan sampling recording method, three macaques were noted having stereotypical anomalies behavior such as, weaving, rocking, and hand-biting. The monkeys were housed into two types of housing that we considered as stable and unstable social housing. Based on literature studies, the suppression of stereotypical anomalies behavior in monkeys are almost impossible in unstable social housing and stereotypical anomalies behavior are observed in some human conditions which considered as neuropsychopathology cases. Due to this similarity, we concluded that Macaca fascicularis could develop as animal model for neuropsychopathology.

Judul: Perbaikan Proses Pemurnian Gliserol Hasil Samping Industri Biodiesel Menggunakan Distilasi Vakum
Abstrak: Gliserol dari hasil samping industri biodiesel minyak sawit setiap tahun jumlahnya kian meningkat. Gliserol tersebut umumnya hanya memiliki kadar gliserol 40-50% karena masih banyak mengandung pengotor berupa sisa metanol, sisa katalis, asam lemak, air, maupun bahan pengotor lainnya sehingga perlu ditingkatkan kemurniannya agar dapat digunakan di berbagai industri dan meningkatkan nilai jualnya. Salah satu cara yang digunakan untuk memurnikannya adalah dengan penambahan asam fosfat yang dapat meningkatkan kadar gliserol dari 47% menjadi 83%. Penelitian ini bertujuan untuk mendapatkan kondisi proses pemurnian gliserol (±80%) menggunakan metode distilasi vakum untuk menghasilkan gliserol dengan kadar lebih tinggi (±90%). Kondisi terbaik proses pemurnian gliserol melalui metode distilasi vakum adalah pada suhu 90-95°C dan tekanan 15 InHg (0,51 Bar) dengan kecepatan pengadukan 300 rpm selama 2 jam. Kondisi tersebut menghasilkan gliserol dengan kadar gliserol 94,19%, kadar air 0,01%, kadar abu 2,96%, kadar MONG 2,84%, densitas 1,261 gr/cm3, specific gravity 1,264, viskositas 214 cP, viskositas kinematis (40°C) 106 cSt, warna kuning kecoklatan, pH 6,2, bilangan asam 3,88 mg KOH/g sampel, titik didih 110°C, titik nyala >140°C, titik tuang -30°C, dan titik awan -21°C. Hasil ini menunjukkan bahwa suhu yang digunakan pada proses distilasi vakum telah memberikan pengaruh yang signifikan terhadap karakteristik gliserol murni yang dihasilkan.
