Judul: Performa Obesitas  Monyet Ekor Panjang (Macaca fascicularis) yang Diberi Pakan Berenergi  Tinggi
Abstrak: The aim of this research was to found obesity performances of long-tailed macaques (Macaca fascicularis) which fed with high energy diet. Two groups of five adult males (average body weight 4-6 kg) were treated by three types of high energy diets (A treatment, B treatment and C treatment). Body measurements which observed were crown-rump length; the circumferences of calf (of leg), thigh, hip, waist, chest, arm, and head; thicks of meta-tarsale and meta-carpale; skin fold thickness of arm, back, and stomach; body weight and body mass index (BMI). Data were analyzed by ANOVA, with nested design. The result showed that obesity performances of long-tailed macaques which fed with high energy diet were significantly (P<0.01) for circumferences of hip, waist and chest; skin fold thickness of back and stomach; body weight and body mass index. Body mass index of long-tailed macaques on treatment high energy diet with raw material tallow and yolks indicated became pre- obese with base on Asia people BMI standard with BMI’s average 24.85.

Judul: Profil Darah Monyet Ekor Panjang (Macaca Fascicularis) Yang Diberi Pakan Berenergi Tinggi Pada Periode Obesitas Empat Bulan Kedua
Abstrak: The aim of this research was to observe Macaque’s (Macaca fascicularis) blood and get information of the haematology. This research was done during four months with four times collected, at IndoAnilab, Taman Kencana, Bogor and were analysed in pathology and lipid laboratory of primate centre, Pusat Studi Satwa Primata (PSSP), Bogor. Macaca fascicularis were being fed with three kinds of diets. Two kinds were high energy diet with different composition, both with tallow but one with yolk egg and the other one with monkey chow. There were fifteen adult males M. fascicularis and every five monkeys got different maintenance. This research observed erythrocytes number (million/ml), haemoglobin concentration (g/dl), hematocrit value (%), Mean Corpuscular Volume (MCV), Mean Corpuscular Haemoglobin (MCH), Mean Corpuscular Haemoglobin Concentration (MCHC) the differentiations of leucocytes (eosinophil, neutrophil, basophil, lymphocyte and monocyte). The results of this research were high energy diet extremely significant (P<0.01) affected in erythrocytes number, haemoglobin concentration, hematocrit value, MCV and MCH. Periods nested in treatment extremely significant (P<0.01) affected in erythrocytes number, haemoglobin concentration, hematocrit value, MCHC and significant (P<0.05) affected in monocyte. Positive relationship was present between erythrocytes number, haemoglobin concentration and hematocrit value as well as MCV, MCH and MCHC. Negative relationship was present between lymphocyte and neutrophil. The highest influence showed in high energy diet with tallow and yolk egg.

Judul: Sintesis kompleks salen Cu/Ni sebagai katalis oksidasi gliserol
Abstrak: Biodiesel sebagai salah satu alternatif pengganti minyak bumi telah menghasilkan produk samping berupa gliserol kasar. Salah satu cara pemanfaatan adalah dengan mengoksidasinya menjadi dihidroksiaseton menggunakan kompleks senyawa salen yang telah dihidrogenasi dengan logam atom pusat Cu dan Ni. Katalis yang dihasilkan dicirikan menggunakan spektrofotometer inframerah transformasi Fourier dan spektrofotometer serapan atom. Kinerja kedua katalis dalam mengoksidasi gliserol telah dibandingkan dengan baik dalam penelitian ini. Oksidasi gliserol dilakukan dengan tambahan katalis sebanyak 5 mol% gliserol dalam campuran gliserol-asetonitril. Reaksi dilakukan dengan melewatkan gas oksigen selama 4 jam pada suhu ruang dalam campuran tersebut. Hasil oksidasi dianalisis menggunakan kromatografi cair kinerja tinggi. Puncak kromatogram dari hasil oksidasi yang muncul setelah menit ke-9 menunjukkan terjadinya perubahan gliserol. Produk oksidasi gliserol diduga memiliki gugus fungsi keton karena nilai Rf-nya lebih besar daripada gliserol, yang menandakan senyawa tersebut lebih nonpolar daripada gliserol. Kromatogram yang diperoleh menunjukkan bahwa aktivitas katalis Cu(salen) mengoksidasi gliserol lebih baik ditinjau dari rendemen produk yang dihasilkan dibandingkan dengan Ni(salen). Oksidasi baik dengan Cu(salen) maupun Ni(salen) menghasilkan satu produk oksidasi.
