Judul: Gambaran Darah Kambing yang Diinfeksi Metaserkaria Fasciola gigantica
Abstrak: Penelitian ini dilakukan untuk melihat gambaran darah kambing yang diinfeksi metaserkaria Fasciola gigantica selama 12 minggu. Sebanyak 20 ekor kambing jantan berumur enam bulan dikelompokkan dalam tiga kelompok yaitu F1 yang diinfeksi 200 metaserkaria, F2 yang diinfeksi 400 metaserkaria dan K tidak diinfeksi. Pakan pelet digunakan dalam penelitian ini. Sampel darah kambing diambil dari daerah vena jugularis setiap dua minggu sebelum dare setelah diinfeksi. Parameter yang dilihat berupa jumlah eritrosit, hermoglobin dan hematokrit selama 12 minggu. Hasil dari infeksi fasciolosis menunjukkan tidak ditemukan telur cacing dalam pemeriksaan tinja pada akhir penelitian. Pada pemeriksaan post mortem juga tidak ditemukan cacing dewasa pada hati. Hasil pengamatan gambaran darah terlihat fluktuatif namun perubahan jumlah eritrosit terlihat tinggi pada minggu ke 12. Sementara itu, perubahan hemoglobin dan hematokrit masih berada dalam kisaran normal. Berdasarkan hasil penelitian ini, infeksi dengan 200 dan 400 metaserkaria Fasciola gigantica tidak berpengaruh pada jumlah eritrosit, hemoglobin dan hermatokrit…

Judul: Gambaran Darah Kambing yang Diinfeksi Metaserkaria Fasciola gigantica
Abstrak: This research was conducted to investigate the blood profile of infected goat with Fasciola gigantica metacercariae. A total of 20 male goats, six old months were allocated in three groups namely F1 that infected with 200 metacercariae, F2 that infected with 400 metacercariae and K were not infected. Pellets were used to feed the goats in this study. The blood samples were collected from jugularis vein before and after the infection every two weeks and the parameters analyzed were erythrocytes count, hemoglobin and hematocrit for 12 weeks. The fasciolosis infection results showed that the eggs were not found in feces examination at the end of research. The adult flukes also were not found at the liver during the post mortem examination. The blood profile observations were fluctuated and the highest changes of erythrocytes were observed at 12th weeks post infection, while the changes of hemoglobin and hematocrit were still within the normal range. Based on this study, the infection of 200 and 400 Fasciola gigantica metacercariae did not influence the erythrocytes count, hemoglobin and hematocrit.

Judul: Peran Surfaktan Setiltrimetilamonium Bromida dan Natrium Dodesil Sulfat pada Sintesis ZnO dengan Metode Hidrotermal
Abstrak: Zno crystal is the main preference material in various applications recently, such as in semiconductors, ultraviolet lasers, and catalysts. This study aims to synthesize ZnO with addition of surfactant. ZnO crystals were synthesized by reacting ZnSO4, KOH, and surfactants using hydrothermal method. The first step was to determine the best ratio of ZnSO4: KOH (1:2; 1:3; 1:4, and 1:5) based on X-ray diffraction. The second step was to evaluate the role of surfactan cetyltrimethylammonium bromide (CTAB) and sodium dodecyl sulfate (SDS) on the synthesis of ZnO crystals. The result of this study showed the best ratio of ZnSO4:KOH was 1:3, based on the least of impurities and the highest degree of crystallinity (85.64%). The addition of surfactant CTAB and SDS in the synthesis of ZnO increased the degree of crystallinity, which were 98.28% and 92.17%, respectively. Based on mathematical calculation using Scherrer equation, the crystal size without surfactant was 32 nm, whereas with CTAB and SDS the crystallited size were 28 nm and 29 nm, respectively. The degree of crystallinity and crystal size indicated that CTAB surfactant produce ZnO crystals with the best characteristics as compared to SDS surfactant or without surfactant.
