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 Helminth Infections in Small Ruminants at PT Jonggol Mitra Amanah, Bogor
Abstrak: Ternak ruminansia kecil seperti kambing dan domba merupakan usaha budidaya ternak yang umum digemari masyarakat Indonesia. Salah satu faktor penting yang perlu diperhatikan dalam memelihara ternak kambing dan domba adalah faktor kesehatan, di antaranya infeksi cacing saluran pencernaan. Penelitian ini bertujuan mengidentifikasi jenis dan mengukur derajat infeksi cacing saluran pencernaan pada kambing dan domba di PT Jonggol Mitra Amanah, Kabupaten Bogor. Pemeriksaan sampel tinja menggunakan metode kualitatif yaitu pengapungan sederhana dan modifikasi filtrasi sedimentasi, serta metode kuantitatif yaitu McMaster. Pemupukan tinja dilakukan untuk mengidentifikasi jenis larva infektif strongylid dan Strongyloides. Jenis cacing saluran pencernaan yang ditemukan pada kambing dan domba di PT Jonggol Mitra Amanah adalah Strongyloides sp., Haemonchus sp., Trichostrongylus sp., Oesophagostomum sp. Selain jenis tersebut, pada kambing ditemukan juga Moniezia sp. Tingginya derajat infeksi dan tingkat prevalensi cacing disebabkan oleh sistem pemeliharaan semiintensif, lingkungan peternakan yang sesuai untuk perkembangan cacing, serta pengulangan pemberian obat anthelmintik yang belum efisien., Small ruminant such as goats and sheep are commonly herbivore livestocks kept by farmer in Indonesia. An important factor to be considered in maintaining goats and sheep is their health, including gastrointestinal helminth infections. This study aims to identify the types and measure the degree of gastrointestinal helminth infections in goats and sheep at PT Jonggol Mitra Amanah, Bogor. Fecal samples were analyzed using a combination of qualitative techniques, specifically simple flotation and modified sedimentation filtration. Additionally, a quantitative method called McMaster was also used in the analysis. Fecal culture was performed to obtain infective strongylid and Strongyloides larvae for further identification. The gastrointestinal helminths found in goats and sheep at PT Jonggol Mitra Amanah were Strongyloides sp., Haemonchus sp., Trichostrongylus sp., and Oesophagostomum sp. In addition, Moniezia sp. was also found in goats. The heavy infection degree and high prevalence of helminthiasis were caused by semiintensive farming system, suitable environment for worms, and inefficient repetition of anthelmintic administration.

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).
