Judul: Gastrointestinal Nematode and Coccidia Infection of Sheep at Sugih Mukti Sheep Farm Group, Neglasari Village, Dramaga, Sub District, Bogor Regency. Supervised
Abstrak: Small ruminant farming is important for Indonesian agricultural productivity. Gastrointestinal parasites harm sheep production systems by causing weight loss decreasing in reproductive performance and death. The distribution of gastrointestinal parasite on sheep worldwide and found in all regions of Indonesia. The purpose of this research was to identify and measure the prevalence and intensity of gastrointestinal nematode and coccidian infection on sheep at Sugih Mukti Sheep Farm Group, Neglasari Village, Dramaga, Sub District, Bogor Regency. Fecal samples were collected from 43 sheep from Sugih Mukti Sheep Farm Group. Samples were examined for gastrointestinal parasites using the flotation method, modified McMaster method, and continued by making fecal culture to obtain and identify infective larvae of strongyle. The results of the study showed that the prevalence of strongyle and coccidia infection of sheep on the Sugih Mukti farm was 60.5% and 100% respectively. Prevalence of strongyle infection occurs in 1/8 males (12.5%) and in 25/35 females (71.4%). Prevalence of strongyle occurs in 7/22 young (31.8%) and in 19/21 females (90.4%). Prevalence of coccidia is in all 43 samples for both gender and age. The prevalence of strongyle based on both gender and age were showing the significant difference (P≤0.05) for each category respectively. The average intensity of infection for strongyle in gender and age showed a significant difference (P≤0.05). The average intensity of infection for coccidia in age showed a significant difference (P≤0.05), but showed no significant difference in gender (P≥0.05).

Judul: Gastrointestinal Nematode Infection of Cattle in West Lore Subdistrict of Poso Regency, Central Sulawesi
Abstrak: The current prevalence of gastrointestinal nematodes of cattle in West Lore is not known. This study was conducted to determine the prevalence and intensity of gastrointestinal nematode infection in cattle in the West Lore sub district of Poso Regency in Central Sulawesi. Fecal samples were examined using simple floatation techniques, and the McMaster counting chamber was used for egg count per gram feces (EPGF). In this study the prevalence of gastrointestinal nematodes was analysed in relation to overall prevalence, intensity of eggs per gram of feces and age. Based on microscopic examination, the type of nematode eggs that were found were only Strongyle eggs in all samples. The overall prevalence based on the 41 fecal samples was found to be 58.54%. The majority intensity of eggs per gram of feces is 100 eggs per gram of feces at 29.26%. While it was found that the prevalence of gastrointestinal nematodes is higher in young cattle (65.38%) than in adult cattle (42.85%).

Judul: Sintesis BaTiO3 dari BaCl2 dan TiCl4 dengan Metode Hidrotermal
Abstrak: Increasing technology has lead to proliferating electronic equipments. One component of electronic equipment is capacitor, which can be made of barium titanate (BaTiO3). This study aims to synthesize and to characterize BaTiO3 from a mixture of BaCl2 and TiCl4 by observing changes in temperature and the stage of the reaction. This study was carried out in several stages, i.e synthesis of BaTiO3 by hydrothermal method, changes in the reaction steps, changes in pH, compared the results by nonhydrothermal method and characterization by X-ray diffraction (XRD). Based on XRD results, synthesis of BaTiO3, using the method of hydrothermal (T = 120-150 °C), changes in the reaction steps, also in pH, had not been able to produced pure BaTiO3. It can be seen from low intensity of BaTiO3 and presence of other impurities in the form of TiO2 as can be found in all methods including non-hydrothermal method (T = 600 °C).
