Judul: Studi tingkah laku seksual pasangan Macaca nemestrina dan Macaca fascicularis dewasa di Pusat studi satwa Primata LP-IPB, Bogor
Abstrak: Penelitian ini dilakukan berdasarkan adanya suatu pemikiran untuk menangkarkan dua spesies Macaca berbeda ke dalam satu areal yang sama dengan pertimbangan efisiensi lahan dan harapan untuk memperoleh hewan model biomedis baru yang lebih baik. Tujuan penelitian adalah untuk mengetahui tingkah laku seksual pasangan M. nemestrina dan M. fascicularis dewasa yang ditempatkan dalam kandang dengan luasan terbatas serta untuk mendapatkan informasi keturunan silangnya.

Judul: Perilaku Seksual Monyet Ekor Panjang (Macaca fascicularis Raffles 1821) di Penangkaran Semi Alami Pulau Tinjil, Kabupaten Pandeglang, Provinsi Banten
Abstrak: Long-tailed macaque (Macaca fascicularis Raffles 1821) is one of primate species that has not been protected in Indonesia. The wild caught tended to exceed the wild capture quotas that have been set by the government (Rameiyanti & Purnama 2008). This wild capture can reduce the sustainability of this species, so it should be an effort to prevent extinction by conservation effort such as establishing a captive breeding. One of the most important aspect to the succees of captive breeding is animal reproduction, especially sexual behavior. By knowing the sexual behavior of the macaque, it can be known about the appropriate form of management in order to produce a suitable animal production. The objectives of this study were to determine sexual behavior of the long-tailed macaque in Semi Natural Habitat Breeding of Tinjil Island (SNHBTI) and the influences of sexual behavior to daily behavior of long-tailed macaque. This research was conducted in SNHPTI, Pandeglang, Banten from June to August 2009. The study started on 5 to 10 May 2009 to determine location during preliminary observations by establishing the line transect method. Behavioral data was recorded using behavior sampling method during their active time at 06.00-10.00 WIB and 14.00-18.00 WIB. There was 29 group of the macaques in SNHBTI but only group 3 was observe for this study. The sample unit consist of 5 males and 4 females. The result shows that long-tailed macaques in group 3 spent 20% of their active time to eat, 3,9% drinking, 39,6% moving, 21,4% resting, 3,7% grooming, 4,6% agonistic and 6,8% for sexual activity. Sexual activity is frequently done in the morning. This activity also frequently taken place on the trees. The position of the monkey in the social hierarchy positively correlated with the frequency of male sexual behavior and negatively correlated with the frequency of female sexual behavior. There are types of sexual behavior in long-tailed macaque. The highest frequency was approach-genital inspection. Sexual behavior in males have positively correlated with eating, moving, and resting behavior, and also have a significant influence on eating and moving behavior. Sexual behavior at non-pregnant females have negatively correlated and give significant influences to eating behavior. Sexual behavior at pregnant female has negatively correlated with eating behavior, positively correlated and give significant influences to resting behavior.

Judul: Elektrodeposisi Film Tipis Semikonduktor Cu2ZnSnS4 (CZTS) pada Substrat Kaca ITO
Abstrak: Semiconductor Cu2ZnSnS4 (CZTS) thin film that can be used as absorber layers on solar cell module was made via electrodeposition method. CZTS thin film was electrodeposited on the surface of a silicate glass coated with a thin layer of indium tin oxide (ITO). Deposition process was done using potentiostatic mode at room temperature with a potential of 1.05 V for 30, 45, and 60 minutes, followed with annealing the film at 2 different temperatures, 500 ºC using furnace and 180 ºC using hot plate, both treatments for 45 minutes in N2/H2S atmosphere. The X-ray difractograms were analyzed using Match 2 program and showed that the CZTS thin films had kesterit crystalline structure, with a low percentage of CZTS phase. The thin film also contained secondary phases such as Cu2S, ZnS, and SnS. The obtained CZTS thin films had a thickness between 1.039 and 1.676 μm. Absorption study showed that the band gap energy of CZTS thin films which was annealed using furnace ranged from 1.50 to 1.52 eV, whereas that annealed using the hot plate was not observed. The band gap energy value showed that CZTS thin films can be used as sunlight absorber layers on solar cell. The formation of CZTS crystal film on this investigation was effectively performed using furnace annealing process at a temperature of 500 ºC with deposition time of 45 minutes.
