Judul: Gambaran umum konsumsi dan penggunaan pakan pada tarsius betina(Tarsius bancanus) di penangkaran
Abstrak: Indonesia memiliki kekayaan alam berupa flora dan fauna yang mempunyai banyak kegunaan. Diantara kekayaan alam tersebut, kekayaan fauna yang dimiliki adalah satwa liar. Satwa liar dapat bermanfaat bagi manusia, baik sebagai satwa penelitian maupun sebagai hewan peliharaan/kesayangan. Kegiatar manusia untuk memenuhi kebutuhan hidupnya seperti pembukaan hutan untuk tenmpat tinggal dan ladang berpindah membuat habitat satwa terrsebut menjadi berkurang, selain itu perdagangan satwa liar yang tidak terkontrol juga akan mengakibatkan punahnya satwa liar. Penangkaran merupakan salah satu usaha yang dapat dilakukan untuk menjaga kelestarian satwa liar yang dilindungi. Tarsius hancanus merupakan salah satu satwa liar yang dilindungi saat ini. Tarsius adalah salah satu famili tarsiidae yang tergolong dalam ordo primata. Tarsius merupakan hewan nocturnal (aktif dimalam hari) dan arboreal (hidup di atas pohon). Satwa ini di Indonesia hanya terdapat di P. Bangka. Sumatera, Kalimantan dan Kepulauan Natuna. Tujuan dari penelitian ini adalah untuk mengetahui gambaran umum konsumsi dan penggunaan pakan pada tarsius betina di penangkaran. Penelitian ini dilakukan dari tanggal 3 Juli sampai dengan 7 September 2004 di Penangkaran Mamalia Kecil Bidang Zoologi, Pusat Penelitian Biologi-LIPI, Cibinong, Bogor. Tarsius yang digunakan adalah tiga ekor tarsius betina (Tarsius bancanus) yang berasal dari P. Bangka dengan bobot badan awal penelitian masing-masing 89, 96 dan 84 g (rataan 89,67 ± 6,03 g). Rataan konsumsi pakan dari ketiga tarsius adalah 4,05 0,14 g BK/hari atau sekitar 4,01 ± 0,24% dari bobot badan. Pakan yang diberikan berupa jangkrik dan belalang yang masih hidup. Jangkrik dan belalang mempunyai nilai koefisien cerna semu bahan kering yang cukup tinggi yaitu rata-rata 84,13 0,63%. Rataan konsumsi zat makanan diantaranya adalah abu 4,12 0,04%; protein kasar 64,52 ± 0,49%; lemak kasar 12,82 ± 0,68%; serat kasar 6,59 ± 0,11%; bahan ekstrak tanpa nitrogen (BETN) 12,03 0,79% dan Energi Bruto (EB) 23,54 ± 0,67 kkal/hari. Rataan pertambahan bobot badan adalah 0,55 0,21 g/hari dengan efisjensi penggunaan pakan (EPP) 13,39 ± 4,66%. Rataan Rasio efisiensi protein (REP) pada tarsius adalah 0,21±0,07 %, dan rataan Total Digestible Nutrient (TDN) tarsius adalah 67,42+0,97%. Hasil ini dapat digunakan sebagai acuan dalam pembuatan ransum tarsius khususnya di penangkaran.

Abstrak: Indonesia is known as a country which has various spesies of flora and fauna. Many of them are becoming extinct these animal are very useful as an object of experiment and also as pet animals. Nowadays wild animals in Indonesia are facing serious problem by increasing in rate of extinction due to evolution and human unwise management of nature. Therefore, preventing the extinction of wild animals can be done by conservation and protection of wild animals in captivity. Tarsius bancanus is one of distinct animal that should be protected. Tarsius bancanus is a nocturnal animal that distributes in Kalimantan, Bangka, Natuna and Sumatera island. Information of feeding activity of Tarsius bancanus is limited, especially in captivity. Feeding activity is an important factor that can influence feed intake. This exsperiment is aimed at studying feeding activity and pattern of feed intake of Tarsius bancanus in captivity at night. Two tarsius from Sumatera, were used in this experiment. Data of activity were recorded which included feeding, drinking, urination, defecation, locomotion, grooming and resting avtivities. In addition, the amount of feed intake and fecal production were also recorded. Data were analized quantitatively and descriptively. The results show that feeding, drinking, urination, defecation, locomotion, grooming and resting activities are 18.98%, 1.20%, 11.95%, 4.53%, 34.48 %, 20.49% and 8.35 %. The highest feeding activity (3.54%) occurs at 18 – 19 p.m. with feed intake is 0.92 gram dry matter (DM). The lowest feeding activity (0.88%) occurs at 0 – 1 a.m. and 3 – 4 a.m with feed intakes 0.23 gram DM. The average daily feed intake is 4.93 gram DM, with the average of cricket intake is 2.54 gram DM and grasshoper intake is 2.39 gram DM. The average daily fecal production is 0.65 gram DM. The average daily protein intake of cricket and grasshoper are 1.53 gram and 1.70 gram. The average daily crude fiber intake of cricket and grasshoper are 0.19 gram and 0.51 gram. The average daily energy intake of cricket and grasshoper are 15.695 ccal and 12.738 ccal. Feeding activity at 18 – 19 p.m. are the highest activity that occurred, this time can be used as a guideline for effective feeding program of Tarsius bancanus in captivity.

Judul: Synthesis of Molybdenum Trioxide (MoO3) by Electrochemical Method for Electrochromics Application
Abstrak: Molybdenum trioxide (MoO3) thin films have been deposited on glass substrates by electrochemical method using ammonium heptamolybdate tetrahydrate ((NH4)6Mo7O244H2O). The films were deposited onto glass substrates as the control temperature at 25○C and annealing treatment at 350○C for 30 mins. The MoO3 thin films were investigated by UV-Vis, X-ray diffraction techniques (XRD), Scanning Electron Microscopy (SEM). The JCPDS card show that orthorhombic MoO3 (α- phase) has been formed. Molybdenum trioxide MoO3 formation was also confirmed by JCPDS card no. 35-0609. The SEM photographs revealed that the spherical and rod-like morphology and their grains size increased with increasing of heating temperatures. The measurement results show that the MoO3 thin film prepared at 350°C transmited about 80% of the visible spectrum. The effect of different heat treatments on surface morphology, thickness and optical properties of the films are discussed in this thesis.
