Judul: Infestasi cacing pada domba ekor tipis dari rumah pemotongan domba rakyat di Bogor
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.

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: Hybrid solar cells of ZnO nanoparticles/chlorophyll was modified metal ions (Zn2+ and Cu2+ )
Abstrak: Zinc Oxide (ZnO) is a n-type semiconductor with a wide the energy band (Band Gap) is 3.37 eV at room temperature and 3.34 eV at low temperature with a large exiton binding energy is 60 meV. ZnO has been synthesized by hydrothermal method, resulting in a decrease in particle size over the duration of the hydrothermal changes. Crystallographic structure of ZnO were characterized using XRD, has shown the characteristic pattern of a hexagonal wurtzite structure, the crystallite size increases to changes in particle size. Changes in particle size has also led to a change in the absorption peak of ZnO as has been demonstrated posted under test using the optical properties of UV-Vis spectrophotometer. Changes of this uptake has also led to changes in the energy band gap, which increases its band gap energy of the particle size. In electronic applications, especially in solar cells. Chlorophyll is considered less effective, because of their very nature are easily degraded as a result of several reactions which are acid, lighting and temperature. The results of the stability test using a halogen lamp 34 W/m2 for 5 hours, that the substitution of chlorophyll with metal ions Zn2+ and Cu2+ has been shown to form more stable than natural chlorophyll. The characterization of the optical properties, the combination of ZnO / chlorophyll in the form of hybrid films has led to a shift in the absorption region of ZnO becomes more widely from the UV to Visible. ZnO/chlorophyll has absorption range of 350-515 nm, ZnO / Zn-feofitin 332-401 nm and 332-632 nm for Cu-feofitin. The combination of ZnO/chlorophyll and CuSCN as a solid electrolite in hybrid solar cell, a modified chlorophyll with metal ions Zn2+ and Cu2+ has been shown to form a more stable I-V curve. It is characterized by its fill factor value greater than natural chlorophyll. Nevertheless, solar cells with natural chlorophyll has been able to produce higher efficiency values of chlorophyll were substituted.
