Judul: Perilaku seksual monyet ekor panjang (Macaca fascicularis) di Bumi Perkemahan Pramuka Cibubur, Jakarta
Abstrak: Sexual behavior is one of interaction between adult or subadult male and female that has significant role in maintaining group existency. Long-tailed macaques live in multi male multi fe~nale group, polygamous, and has no breeding season. Sosial behavior influenced by sosial hierarchy. Sexual behavior consists of mounting, intromission, thrusting, ejaculation, and dismounting. The objective of this study was to assess sexual behavior of long-tailed macaque (M. fasciszrlaris) in Bumi Perkemahan Pramuka Cihubur, Jakarta. The observation was carried out using ad libitum sampling and focal animal sampling. Daily activities were observed between 06.00 a.m. and 06.00 p.m. for 80 days (329 hour 17 minutes). Sexual activity occured in 2.33 % of total daily activity, and slowed higher frequency in the morning (06.00-10.00 a.m.) than other period of time: afternoon (10.00 a.m.-02.00 p.m.) and evening (02.00-06.00 p.m.). Sexual activity was identified has higher frequency on the ground than other places. The average duration of copulatory was 4.19 second. The high rank male did a lot of copulation, and genital inspect. Mostly, copulation occured without genital inspect. Male and female monkeys are more likely to take a rest after copulation.

Judul: Perilaku Seksual Monyet Ekor Panjang (Macaca fascicularis) di Telaga Warna Bogor.
Abstrak: Long tailed macaques Macaca fascicularis lives in the multi-male multifemale group. The macaques did social interactions such as groomning, playing, sex and agretion. Sexual behavior is interaction between adult male with adult female. This research aim to know about sexual behaviour of long tailed macaques in Natural Recreation Park Telaga Warna, Bogor. The observation is done with ad libitum and scan sampling method. Sexual behaviour mostly occured in the morning between 07.00 until 11.00 am. Inspection was the most frequence sexual behaviour. Social hierarchy was not related with the frequency of sexual behaviour, except for courtship.

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.
