Judul: Studi Pakan Owa jawa (Hylobates moloch Audebert 1798) di Pusat Penyelamatan dan Rehabilitasi Satwa Javan Gibbon Center (JGC)
Abstrak: Javan Gibbon is a protected animal based on PP RI no. 7 1999. The problems in nature habitat are fragmentation, illegal logging, illegal hunting and illegal trade. One of the ex-situ conservation effort is by building Javan Gibbon Rescue and Rehabilitation Center. Feed management in conservation institution is needed in order to choose feed priority by seeing the palatability and nutrition intake. The purpose of this research are to identify the palatability, nutrient intake and the relation beetween diet menu with the amount of feed election, feed consumption, and energy intake. Focal animal sampling and restricted feeding are used by giving two different diet menu. The first rank of palatability is banana for the first menu and the second menu. The amount of the energy intake from the first menu is 327.47 kcal and from the second menu is 351.27 kcal. There is no significant deferences between diet menu with the mount of feed selection, feed consumption and energy intake.

Judul: Studi Perilaku dan Pakan Owa Jawa (Hylobates moloch) Di Pusat Studi Satwa Primata IPB dan Taman Nasional Gunung Gede Pangrango : Penyiapan Pelepasliaran, Study of Behavior and Feeding of Javan Gibbon in Primate Research Center IPB and Gunung Gede Pangrango National Park : Preparation of Release
Abstrak: Owa Jawa (Hylobates moloch, Audebert 1797) merupakan satu dari lima spesies genus Hylobates yang hidup di Indonesia. Berdasarkan Laporan Conservation Assessment and Management Plan PrimataIndonesia (Supriatna, et.al. 2001), saat ini diperkirakan hanya tersisa antara 400-2.000 individu spesies kera ini di habitat alaminya. Hal ini terjadi karena adanya tekanan atau degradasi habitat Owa Jawa dan perdagangan liar satwa ini sebagai hewan peliharaan (Supriatna 2006). Melalui program pelestarian Owa Jawa secara eksitu diharapkan mampu menunjang konservasi in-situ melalui program pelepasliaran ke habitat alaminya. Studi komparasi antara perilaku di alam (insitu) dan di habitat eksitu merupakan kunci bagi program konservasi spesies dan solusi bagi permasalahan tersebut. Hasil kajian mengenai komparasi dirumuskan sebagai dasar dalam penentuan kebijakan dan arah kegiatan pengelolaan manajeman eksitu di PSSP. Studi ini ditunjukan dalam rangka menyiapkan individu di penangkaran sehingga mampu beraktivitas dan berperilaku serta memanfaatkan pakan sebagai mana ketika berada di alam serta ditunjukan dalam penetapan kriteria kesiapan individu yang akan dilepasliarkan. Data-data yang dikumpulkan meliputi data primer dan sekunder. Pengamatan dilakukan secara langsung dilapangan terhadap aktivitas dan perilaku serta pakan Owa Jawa baik di PSSP maupun di Hutan rasamala (Taman Nasional Gunung Gede Pangrango) serta melalui studi literature yang relevan dengan bidang kajian. Pengumpulan data primer meliputi data kondisi bio-fisik, pengkayaan lingkungan kandang Owa Jawa, aktivitas dan perilaku, serta pakan.

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.
