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: 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.
