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: 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: Pembuatan Film Tipis Cu2ZnSnS4 sebagai Lapisan Penyerap Cahaya pada Sel Surya Menggunakan Metode Elektrodeposisi
Abstrak: Thin film of Cu2ZnSnS4 (CZTS) is an alternative semiconductor used as light absorber layer on solar cell. CZTS can replace silicon that commonly used as commercial semiconductor. The advantage of using CZTS as absorber layer is due to the abundance of its chemical composer on earth, and its high value of absorption coefficient. The absorber layer was made by using electrodeposition method on ITO glass substrates. The films were deposited at room temperature using potentiostatic mode with a potential of –1.05 V for 30, 45, and 60 minutes. After that, the films were annealed at two different temperatures, 180 ºC and 500 °C, for 45 minutes in N2/H2S atmosphere. Based on X-ray diffraction analysis, the polycrystalline thin film obtained fall into kesterite crystal phase. This type of crystal was obtained when the CZTS was annealed at 500 °C in H2S/N2 atmosphere. The value of optical band gap energy for the CZTS thin film was 2.2 eV with the film thickness about 1.228–6.366 μm. The sample of CZTS with electrodeposition time of 45 minutes and annealing temperature of 500 °C showed the best result and in conformity with absorber layers criteria for solar cells.
