Judul: Sifat Karkas dan Non-Karkas Sapi Silangan Lokal pada Berbagai Kondisi Perlemakan Tubuh
Abstrak: The study was aimed to examining the effect of body condition score (BCS) of local crossbreed cattle on carcass and non-carcass characteristics. This study used 73 bulls of local crossbreed cattle slaughter on state abbatoar at West Java, Central Java, and East Java. The slaughter weight, carcass and non-carcass weights at different BCS were recorded. The collected data were analyzed by analysis of variance (ANOVA) using general linear model (GLM) procedure. The differences between BCS were tested using Duncan multiple range test. Result showed that increased of BCS from 2 to 4, slaughter weight and carcass weight were increased (P<0.05), except carcasses dressing percentage. The non-carcas weight obviously increased with increasing body condition score (BCS). However significant between BCS differences in non-carcas characteristics occurred only in percentages of offal and tail.

Abstrak: Body condition score (BCS) is one indicator to know high or low of fat and meat deposit on carcass and non carcass from an animal. The purpose of the research to evaluated carcass and non carcass characteristic of thin-tailed sheep (DET) on Body condition score (BCS) effect at slaughter house Maleber, Bogor. Research used 99 heads of DET. The sheep grouped into 3 group BCS, thin (1), medium (2) and fat (3) . Data were analyzed by Analysis of Variance (ANOVA). The result showed DET with BCS 3 (fat) were significant different higher live weight, carcass weight, and empty body weight from the other BCS (thin and medium). Carcass’s percentage on BCS effect showed same value from efect value of BCS 1, 2, and 3 . The differences of body condition score effect to non carcass characteristic were significantly (P<0.01) on weight and diverse on percentage whereby on the percentage of liver and rumen is different (P<0.05) but peresentase other components except heart, spleen and skin very different (P<0.01) . The percentage of weight from spleen, skin, and blood is not effected by BCS.

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.
