Abstrak: Perilaku Agonistik Monyet Dewasa dan Muda Monyet Ekor Panjang (Macaca fascicularis) di Makam Kramat Banjar Jatibarang Kabupaten Indramayu. Dibimbing oleh R.R. DYAH PERWITASARI dan ENTANG ISKANDAR. Perilaku agonistik pada monyet dewasa dan muda merupakan perilaku pertentangan, mengarah perkelahian karena terjadinya kompetisi. Pada penelitian ini dipelajari bentuk dan frekuensi perilaku agonistik antara sesama monyet dewasa, monyet muda, serta antara monyet dewasa dan muda baik pada jantan maupun betina Macaca fascicularis di Makan Kramat Banjar Jatibarang. Pengamatan dilakukan dengan menggunakan metode pengambilan contoh ad libitum, scan sampling, dan focal animal. Perilaku yang diamati mencakup mencabik, menggigit, mengejar, mengancam, menelisik, dan tiga respon individu (bared teeth, presentation, lip-smack) dalam menyikapi perilaku agonistik. Perilaku agonistik dipengaruhi oleh tingkat hirarki individu dalam kelompok. Perilaku agonistik pada monyet dewasa dan muda yang diamati memiliki frekuensi yang semakin besar sejalan dengan semakin tingginya tingkat hirarki individu tersebut.

Judul: Perilaku Afiliasi dan Perilaku Agonistik Monyet Ekor Panjang (Macaca fascicularis) Dewasa di Telaga Warna, Bogor Jawa Barat
Abstrak: Macaca fascicularis lives in social groups consist of multi males and multi females with a hierarchical social structure. M. fascicularis engages social interaction in the group. Social interaction could be an afiliation, agonistic, and sexual behaviour. This research aims to study afiliation and agonistic behaviour of a group of M. fascicularis in Telaga Warna Nature Recreational Park, Bogor West Java. This study was held from February to May 2013. M. fascicularis interactions was observed using scan sampling and ad libitum sampling. This research showed that social hierarchy is related to the frequency of afiliation and agonistic behaviour of the M. fascicularis. High rank males and high rank females showed proximity to individuals with similiar rank. Proximity occured higher within males-females than males-males and females-females. High rank individuals groomed more often than low rank individuals. High rank individuals intimidates more often than the mid or low rank individuals. High rank individuals attacks more often than the mid or low rank individuals.

Judul: Pembuatan Film Tipis Cu2ZnSnS4 sebagai Lapisan Penyerap Cahaya pada Sel Surya Menggunakan Metode Elektrodeposisi
Abstrak: Thin film of Cu2ZnSnS4 (CZTS) is an alternative semiconductor used as light absorber layer on solar cell. CZTS can replace silicon that commonly used as commercial semiconductor. The advantage of using CZTS as absorber layer is due to the abundance of its chemical composer on earth, and its high value of absorption coefficient. The absorber layer was made by using electrodeposition method on ITO glass substrates. The films were deposited at room temperature using potentiostatic mode with a potential of –1.05 V for 30, 45, and 60 minutes. After that, the films were annealed at two different temperatures, 180 ºC and 500 °C, for 45 minutes in N2/H2S atmosphere. Based on X-ray diffraction analysis, the polycrystalline thin film obtained fall into kesterite crystal phase. This type of crystal was obtained when the CZTS was annealed at 500 °C in H2S/N2 atmosphere. The value of optical band gap energy for the CZTS thin film was 2.2 eV with the film thickness about 1.228–6.366 μm. The sample of CZTS with electrodeposition time of 45 minutes and annealing temperature of 500 °C showed the best result and in conformity with absorber layers criteria for solar cells.
