Judul: Improvement of the meat productivity of mule ducks by the establish of female line
Abstrak: Crossing two strains of local duck strains with the Pekin duck was conducted to develop two candidate female lines to be crossed with the muscovy duck. The resulting interspecies hybrid is expected to produce a mule duck showing excellent body size, growth rate and feed efficiency. Also other important carcass traits such as breast width and depth, length of thighs and legs solid white plumage preferred by the consumer. The research was conducted at the Research Institute of Animal Production (RIAP), Ciawi. Two strains of local ducks were crossed with the Pekin drake and then to be crossed with the muscovy duck to produce mule ducks. The research was conducted in two phases. The first was crossing the Pekin x Alabio (PA) and Pekin x white Mojosari (PM) ducks producing two candidate female lines. The second phase was crossing the PA and PM ducks with the muscovy ducks by Artificial Insemination (AI). This will produce the EPA and EPM mule duck., Persilangan dua galur itik local dengan itik pekin dilakukan untuk menghasilkan dua calon galur induk yang berprestasi baik untuk dikawinkan dengan entog. Persilangan antara galur induk dengan entog diharapkan menghasilkan mandalung yang memiliki penampilan tubuh (performa) besar, pertumbuhan cepat dan efisien dalam penggunaan pakan. Disamping itu dilihat pula sifat pokok lainnya seperti berdada lebar dan dalam, paha yang panjang sebagai sumber utama daging itik, warna bulu penutup tubuh dan kulit putih polos yang merupakan selera konsumen.

Judul: Respiratory Quoti<mt of Duck (Anas platyrhynchos), Muscovy (Cairina moschata) and Mule Ducic.
Abstrak: Duck, muscovy and mule duck are water jowl that have a great prospect to be developed. Duck is a good water fowl layer. Muscovy can be developed as a m(.;at water fowl and it produces less eggs compared DY duck so that muscovy has a lov..er reproduction ability. Mule duck can be used is a solution for that problem. The additional information for the advancement of mule duck reproduction nowadays still being searched and developed. The information of oxygen consumption of animal can be used as the indicator for knowinB. the metabolism activity and also for estimating the energy metabolism need of animal. This study was done in Poultry Animal Production Laboratory, Faculty of Animal Science, Bogor Agricultural University from January until March 2003. The material that have been used were 12 ducks, 12 muscovies and 12 mule ducks. The entire material were 36 Day Old Ducks that have been kept for eight weeks. The oxygen consumption and carbon dioxide production data were gained by locating the ducks inside the respiration chamber which were supplied by pure oxygen. The first week measurement was used 12 animal for eaGh species. The forth and eight week were used respectively 4 ducks. Respiratory Quotient have been measured based on the oxygen consumption and C(h production fwm each animal.

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.
