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.

Abstrak: There are two kinds of sheep in Java, the thin tail sheep (which is the common livestock in Bogor) and the fat tail sheep. Both type of sheep could be infected by worm parasites in digestive tract, which reduce the health of the sheep. Therefore, the objections of this research were counting and identifying the worm eggs from faecal samples of thin tail sheep which slaughtered in the sheep’s abattoir house in Bogor. From the total 35 samples collection, I found 18 samples were infected by the worm parasites. The worm parasites were found in all sample of males, meanwhile they were also found in half of faecal sample of females. The egg worms that found in this research belonged to six families, they were Schistosomatidae (3,45%), Anoplocephalidae (6,90%), Ascarididae (3,45%), Trichostrongylidae (41,38%), Capillaridae (37,93%) and Trichuriidae (6,90%). The average of worm eggs infestation from all samples were 892 egg/g faeces, which included to the average category of infection degree. This research also showed that the rain had no influence to the eggs number.

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.
