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: Nanokristalin Pirit (FeS2) sebagai Material Semikonduktor Fotovoltaik.
Abstrak: Teknologi fotovoltaik adalah suatu proses yang dapat mengubah sinar matahari menjadi energi listrik dengan media semikonduktor. Penggunaan sel surya untuk fotovoltaik hanya dapat mengonversi radiasi matahari menjadi energi listrik kurang dari 20%. Efisiensi akan meningkat ketika material semikonduktor untuk fotovoltaik dibuat menjadi ukuran nano. Pirit merupakan salah satu material semikonduktor fotovoltaik yang memiliki energi pita celah (Eg) dalam kisaran 0.8–0.95 eV. Energi pita celah tersebut terbukti meningkat ketika disintesis dengan metode hidrotermal menggunakan beragam molar [S]:[Fe] pada suhu 200 °C dalam 24 jam. Nilai energi pita celah yang dihasilkan adalah 1.58–2.073 eV. Ukuran nanokristalin pirit yang dihasilkan berada pada kisaran 21.04–58.77 nm menurut data Particle Size Analyzer. Besarnya ukuran nanokristal pirit yang tumbuh kurang dari 50 nm merupakan poin penting untuk aplikasi fotovoltaik.
