Judul: Telaah Kondisi Anemia yang Disebabkan oleh Cacing Haemonchus contortus pada Kambing dan Domba di Bogor, Jawa Barat
Abstrak: The risks of traditionally goat and sheep treatment particularly in Bogor are low livestock productivity and the high risk of parasite infection, i.e gastrointestinal Nematode. Gastrointestinal Nematode tract most infect goats and sheep in Bogor and causes anaemia is Haemonchus contortus. The 3rd phase larvae of H. contortus can get into the abomasum of goats and sheep through the grass. There are two famous methods to suspect anaemia because of H. contortus, can be based on the number of eggs per gram of feces (Faecal Egg Counts/ FEC) and eyelid color by color gradation FAMACHA© card. FEC indicates the average number of investments H. contortus in the abomasum of goats and sheep. The H. contortus’s eggs found in nearly 153 goats and sheep from traditional farms and UP3 Jonggol that feces examined. Haemonchus contortus attacked goats and sheep at different ages but it attacked mostly at aged 12-16 months. The average of FEC from sheep higher than goats. This is related to the morphology of its mouth and food grassing. The high infection of H. contortus in Bogor due to traditional maintenance. Sheep on traditional farms are more susceptible from H. contortus than UP3 Jonggol’s sheep. The correlation between FEC and age were negative, where as the correlation between FEC with FAMACHA© card is positive. This provides an opportunity FEC and FAMACHA© card methodes used simultaneously to suspect anemia because of H. contortus in Bogor

Judul: The Effect of Larva-3 Haemonchus contortus Infection to Resistant Potency and Blood Values of Indonesian Thin-Tailed Sheep
Abstrak: Salah satu parasit cacing saluran pencernaan yang paling banyak menginfeksi domba di Jawa Barat ialah Haemonchus contortus. Domba yang terinfeksi H. contortus pada umumnya akan mengalami anemia bahkan kematian karena kehilangan darah. Salah satu upaya untuk mengatasi hal ini ialah dengan mengembangkan domba lokal yang tahan infeksi H. contortus yang dapat dianalisis dari gambaran darah sebagai gambaran kondisi fisiologis dan ketahanan ternak tersebut. Sebanyak 20 domba ekor tipis diobati dengan ivermectin sampai terbebas dari infeksi cacing. Sebanyak 18 ekor domba yang bebas cacing diinfeksi dengan L3 H. contortus per oral sebanyak 3000 larva/ekor dan 2 ekor domba tidak diinfeksi sebagai kontrol. Bobot badan, faecal egg count, dan gambaran darah domba diamati selama 42 hari setelah infeksi. Infeksi H. contortus pada domba cenderung menurunkan nilai packed cell volume, kadar haemoglobin darah, jumlah sel darah merah, dan meningkatkan jumlah sel darah putih, namun tidak sampai menyebabkan kondisi anemia. Bobot badan domba tetap meningkat selama masa infeksi, namun laju pertambahan bobot harian domba menurun sampai akhir pengamatan. Nilai gambaran darah yang ditemukan mengisyaratkan bahwa domba ekor tipis memiliki potensi kekebalan terhadap infeksi H. contortus.

Judul: Membran polistirena dengan ragam suhu perendaman untuk pervaporasi alkohol
Abstrak: Polystyrene membrane with PLURONIC as porogen, can be utilized in alcohol pervaporation. The polystyrene membrane was made by reverse phase method which was started with making of polymeric mixed solution between polystyrene and PLURONIC in dichloromethane with 2 different compositions, i.e.-polystyrene :PLURONIC:dichloromethane 17:0:83 and 17:1:82. The solution was stirred up for 5 hours with ultrasonic and casted on the glass plate surface, and then it was immersed into water at 40, 50, and 60 oC. The highest pervaporation result was 90,2% alcohol purities at 50 oC immersion temperature. However, this result was not good enough because the alcohol purities was lower than the standard alcohol purities at 91,6%.
