Judul: Interaksi Hasil Analisis Vegetasi Padang Penggembalaan dan Infestasi Cacing pada Domba di Kabupaten Majalengka, Jawa Barat
Abstrak: The gastrointestinal worm can inhibit the growing rate of sheep. Worm infestation on gastrointestinal of sheep influenced by vegetation composition of grassland when the sheep were kept in pastoral system. The aim of this research is to learn interaction between grassland’s plant composition and gastrointestinal worm diversity within sheep in Kabupaten Majalengka, West Java; and learn methods to determine the presence of worm eggs in faecal sample. Vegetation composition were analyzed using purposive random sampling method. Feces was taken from sheep that it was grazing on the location of grassland. Feces was prepared using floating method and sedimentation method. Worm diversity and FEC in sheep were different between locations. The sheep were grazing on post-harvested rice field has worm diversity and FEC lower than grazing on cane plantation. At locations with plants suspected to contain anthelmintic compound were found lower FEC. The floating method is spesific method to species Moniezia, whereas the sedimentation method spesific to Bunostomum sp.

Judul: Keanekaragaman dan Tingkat Infeksi Cacing Parasit Gastrointestinal pada Domba di Kabupaten Majalengka, Cirebon, dan Sragen
Abstrak: Infestasi cacing parasit gastrointestinal menyebabkan gangguan pertumbuhan pada domba. Keanekaragam dan tingkat infeksi cacing parasit gastrointestinal pada domba dapat diketahui dari telur cacing yang terinfestasi pada fesesnya. Tujuan dari penelitian ini adalah mempelajari keanekaragaman dan tingkat infeksi cacing parasit gastrointestinal pada domba di Kabupaten Majalengka Jawa Barat, Cirebon Jawa Barat dan Sragen Jawa Tengah. Domba yang digembalakan di ketiga lokasi diambil sampel fesesnya. Telur cacing parasit pada sampel feses domba dihitung dengan metode Faecal Egg Counting (FEC) dan diamati jenisnya. Data curah hujan diambil dari stasiun BMKG terdekat. Tingkat infeksi cacing parasit pada domba di ketiga kabupaten tergolong ringan dan sedang. Infeksi berat tidak ditemukan pada domba di ketiga kabupaten. Spesies telur cacing parasit yang ditemukan di ketiga kabupaten adalah Haemonchus sp., Oesophagostomum sp., Trichostrongylus sp., Strongyloides sp., Fasciola sp., Skrjabinema sp., Bunostomum sp., dan Mecistocirrus sp.

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.
