Judul: The Observation of Size and Shape on Mojosarl, Alabio, Bali, Pegagan, Khaki Campbell and Pekin Ducks.
Abstrak: Ducks were kept to produce eggs and meat. Development of duck in Indonesia was done as traditionally by the farmers on low-land area. Breeds of duck with their characteristics were very important as animal genetic resources. Characterization of breeds by morphological is based information for thdr improvement. The research was conducted at Research Institute for Animal Production, Ciawi, Bogor from January to May 2002. The length of femur, tibia, tarsometatarsus, circumference of tarsometatarsus, length of third digit, wing and maxilla bone of Mojosari, Alabio, Bali, Pegagan, Khaki Campbell and Pekin ducks were measured to observe their body size and shape. Data were analyzed by T-Test (steel and Torrie, 1981) and Principal Component Analysis (PCA) (Gaspersz, 1992).

Judul: Morfometrik Itik Cihateup dan Itik Alabio serta Persilangannya yang diberi Pakan Berbeda
Abstrak: The aim of this research was to identify and compare morphometric of Cihateup, Alabio and Cihateup-Alabio crossbreed fed with different ration. This research used 45 females and 36 males ducks. The Feed used in this research was commercial feed, green cabbage and rice bran. The result of this research showed body size performance of males duck more influenced by duck’s types except to maxilla length. The length of femur, tibia, tersometatarsus, and 3rd digit of CA and Cihateup males was larger than Alabio male. The wing length and tarsometatarsus circumference of CA male was larger than Alabio and Cihateup male. The body size of females more influenced by duck’s types except for wing length and circumference of tarsometatarsus. The femur length, tibia length, and 3rd digit length of Cihateup ware larger than CA and Alabion while CA was larger than Alabio female. The Cihateup and CA females ware larger than Alabio female for length of tarsometatarsus. Furthermore the Cihateup female was larger than Alabio duck and CA for maxilla length.

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.
