Judul: The red blood cells profile of infected  javanese thin  tailed sheep  with  haemonchus  contortus  larvae  infective
Abstrak: Penelitian ini bertujuan untuk mengetahui pengaruh derajat infeksi H. contortus terhadap gambaran jumlah sel darah merah, kadar hemoglobin dan nilai hematokrit pada domba ekor tipis. Sebanyak 20 ekor domba ekor tipis jantan berumur 6–8 bulan dikelompokkan menjadi lima kelompok yaitu kelompok kontrol tidak diinfeksi larva infektif (L 3 ) dan kelompok infeksi L3 dengan dosis 500 L3 , 1000 L3 , 2000 L3 dan 4000 L3 . Sampel darah dan tinja dikumpulkan sekali setiap minggu selama tujuh minggu setelah infeksi. Sampel darah diperiksa untuk mengetahui jumlah sel darah merah, kadar hemoglobin dan nilai hematokrit. Sampel tinja juga diperiksa untuk menghitung jumlah telur tiap gram tinja. Hasil penelitian menunjukkan bahwa dosis infeksi L 3 mempengaruhi nilai hematokrit (P<0.05), namun tidak mempengaruhi jumlah sel darah merah dan kadar hemoglobin (P>0.05). Jumlah telur tiap gram tinja (TTGT) berkorelasi negatif namun lemah dengan jumlah sel darah merah, kadar hemoglobin dan nilai hematokrit (P<0.05; R<0.50)., This research was conducted to investigate the effect of H. contortus infection to red blood cell profil of Javanese thin tail sheep. The total of 20 males of Javanese thin tailed sheep age 6-8 months were grouped into five groups namely not infected control group and infective group of 500 L 3, 1000 L 3, 2000 L 3 and 4000 L 3 . The samples of blood and fecal were collected weekly for seven weeks. The blood samples were examined to determine the total of red blood cells, hemoglobin levels and pack cell volume, whereas fecal samples to determine egg per gram. The results showed that the infection dose had the effect to pack cell volume, but the total of red blood cells and hemoglobin levels were not significantly different. The amount of egg per gram were negatively correlated with the red blood cells, hemoglobin level and pack cell volume.

Judul: Gambaran Leukosit Domba Ekor Tipis yang Diinfeksi Haemonchus contortus.
Abstrak: The aim of this study was to investigate the effect of Haemonchus contortus infection to white blood cell profile of Javanese thin tail sheep. Twenty males Javanese thin tailed sheep were divided into five groups, namely infected group of 500 L3, 1000 L3, 2000 L3, 4000 L3 and uninfective group as control. The blood and fecal samples were collected from rectum before and three weeks after infection. The blood samples were collected using venoject® from Jugular vein. The fecal samples were collected directly from rectum. The blood samples were examined to determine total of white blood cell (leukocytes) and white blood cell differential, whereas fecal samples to determine egg per gram. The result showed that Haemonchus contortus infections cause an increased total of leukocyte but were not significantly different among of level infection doses (P>0.05). Number of eosinophils were significantly different among uninfected group (P<0.05), but were not significantly different in number of lymphocyte, monocyte, and neutrophil (P>0.05). There where positively correlated significantly between the amount of egg per gram (EPG) and profile of eosinophil (P<0.05), however were negatively correlated significantly between the amount of egg per gram (EPG) and neutrophil’s profile (P<0.05). There where no correlation significantly between the amount of egg per gram (EPG) and profile of white blood cell, lymphocyte, and monocyte (P>0.05).

Abstrak: Styrofoam waste can be converted to poly–(sulfonate styrene acid) (PSSA) that can be used as catalyst. The objective of this research is to get PSSA that can catalyze the etherification of glycerol and benzyl alcohol. The styrofoam waste was converted to PSSA by reacting with H2SO4 98% (as sulfonation agent) and P2O5 (as sulfonation catalyst) at 40 °C for 6 hours. Characterizations of PSSA included functional groups, sulfonation levels, water swelling, and thermal stability. The yield of PSSA was 40-55%. The success of sulfonated polystyrene was shown by –SO3H group absorption at 1157.29 cm-1. Etherification of glycerol and benzyl alcohol using PSSA catalyst was conducted at 110 °C for 12 hours. The conversion in producing mono–benzyl ether glycerol was 8.10%, 1,3–dibenzyletherglycerol 2.60%, and dibenzyl ether 9.80%. Therefore, the PSSA can be used as etherification catalyst.
