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: 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: Kinerja model pengering bangunan tembus cahaya dari plastik tahan UV untuk pengeringan buah kopi
Abstrak: Kopi merupakan komoditas ekspor yang memerlukan pengeringan sebelum dikonsumsi, sehingga kemampuannya dapat disimpan dalam waktu lama sangat menentukan mutu dan nilai ekonominya. Penyediaan sarana pengeringan yang memadai sangat dibutuhkan untuk mencapai tujuan tersebut. Sebuah model bangunan tembus cahaya untuk pengeringan kopi skala 1.5 ton sudah dirancang dan diuji coba. Bangunan tersebut berukuran 6 m x3 m, tinggi 2.46 m terbagi menjadi dua. yaitu atap 0.56 m dengan sudut kemiringan 32.4" dan dinding 1.9 m membentuk sudut kemiringan 85.6" terhadap lantai. Plastik tahan UV menutupi atap dan dindingnya. Penelitian ini bertujuan menguji kinerja model pengering bangunan tembus cahaya pada kapasitas maksimum. Percobaan dilakukan dengan mengeringkan kopi pada ketebalan 30 cm dan 40 cm (kapasitas penuh) dibantu blower 0.5 11P, 220 volt untuk mengalirkan udara pengering di dalam bangunan tembus cahaya dan mengeluarkan uap air bahan yang telah diuapkan dari bangunan tersebut. Hasil percobaan memperlihatkan bahwa penutup transparan mampu memanfaatkan 70% radiasi matahari yang jatuh di permukaannya. Pada kondisi radiasi termanfaatkan rata-rata sebesar 435.1 W/m². laju aliran udara sebesar 2520...
