Judul: Performa Kuda Delman Sebagai Alat Transportasi Di Kota Bogor
Abstrak: This research was done from March up to April 2009 by observation and interview of coachman that used as draft animal or called “delman” in Bogor. The aim of this research was to collect information of management horse system for human transportation in Bogor. The data were analyzed descriptively. The research showed that the job as coachman was main source of money and doesn’t need a good education to be a coachman. The horses that used for draft animal was Sumba horse. The coachman bought their horse and the equipment in Bandung. The majority of horses has a solid facial marking with brown basic colour of coat. The maintenance management of horses that used by coachman is very traditional because the limited knowledge that coachman known. The coachman have their knowledge from other friends that work as coachman and legacy that have been passed on from one generation to other generation in their family. The presence of technology has been influence the prosperity of coachman and horse. It would have had an effect of maintenance management of horses. The government and coachman play an important role to increase the prosperity of horse with a good maintenance management. Keywords : Equus caballus, delman, traditional transportation

Judul: Status Kesehatan Dan Manajemen Pemeliharaan Kuda Delman Di Kota Bogor
Abstrak: The puiyose of this research was to describe about health condition and care management of Bogor traditional horse camage. The research was done since October 2007 to September 2008 with 30 cabmen as respondent and 12 horses as sample. The data was collected by interviewing cabman and examines the horses. This research showed that nutrition status of the horses was present at value 4 (moderately thin). Skin and coat condition of the horses seen clean, though basically their condition are harsh, not sparkling and there are lots of wounds on horses body. The horse heart rate was range 36 to 56 times per minute. Horse breathe frequency was range 24 to 54 times per minute, while range of body temperature was 37.1 C to 38.1 C. Horse genitals are dirty. Intestine horses peristaltic in general are normal but some horses got hipoperistaltic problem. Horse food cannot fulfill horse nutrition. Stable conditions are endangering the horse. Surface environmental floor are not good for horse hooves. Hoof treatments are not yet done well. Horse health service not involved role veterinarian. Based on the research, we conclude that almost every horse have problem at nutrition and wounds on their body, some horses have problem on inhalation system, circulatory system and dehydration. The care management is still unfavorable and still done traditionally.

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.
