Judul: Pengaruh pemberian pakan tepung dan minyak Ikan Lele, serta Probiotik E. faecium IS-27526 terhadap profil darah Macaca fascicularis betina usia tua
Abstrak: Penelitian ini bertujuan menganalisis pengaruh pemberian pakan tepung ikan lele, minyak ikan lele, serta probiotik E. faecium IS-27526 terhadap profil darah monyet ekor panjang (MEP) betina usia tua. Desain penelitian yang digunakan adalah experimental study selama 90 hari. Contoh dalam penelitian ini berjumlah 9 ekor MEP yang telah mengalami masa adaptasi selama 45 hari. Peneliti membagi contoh ke dalam tiga perlakuan, yaitu kelompok tepung ikan lele (A1), kelompok tepung ikan lele + probiotik (A2), dan kelompok tepung ikan lele + probiotik + minyak ikan (A3). Hasil uji sidik ragam menunjukkan bahwa terdapat perbedaan yang nyata (p<0.05) antara perlakuan dengan perubahan kadar eritrosit, hemoglobin, dan hematokrit. Namun, tidak terdapat perbedaan yang nyata (p>0.05) antara perlakuan terhadap perubahan nilai MCV, MCH, MCHC, leukosit, dan trombosit. Lama intervensi dan interaksi perlakuan dengan lama intervensi juga tidak berpengaruh nyata terhadap profil darah monyet ekor panjang., The aim of this study was to analyze the effect of catfish flour, catfish oil, and probiotic E. faecium IS-27526 based on blood profile of aged female long-tailed monkeys. Experimental design was applied for this study. Feeding trial was conducted in 90 days. Nine monkeys had been conditined on 45 days before this study begun and they were divided into 3 groups of treatment: catfish flour (A1), catfish flour + probiotic (A2), and catfish flour + probiotic + catfish oil (A3). The statistical analysis using ANOVA test showed that significant difference exist (p<0.05) between treatment to the change level of erythrocytes, hemoglobin, and hematocrit. However, no significant difference (p>0.05) were observed between treatment to the change level of MCV, MCH, MCHC, leukocytes, and thrombocytes. The result also showed that the duration of intervention and intervention treatment vs duration of intervention had no significant difference on blood profile of the samples.

Abstrak: This study aimed to determine the effect of probiotic Enterococcus faecium IS-27526 and catfish ( Clarias gariepinus) oil in functional biscuit enriched with catfish flour and sweet potato (Ipomoea sp.) flour on fecal microbiota of aged monkey (Macaca fascicularis). There were 9 female aged Macaca fascicularis adapted for one month before the study, and divided into 3 groups, namely: control group, probiotic E. faecium IS-27526 group, and probiotic E. faecium IS-27526 and fish oil group. After 90 days administration, the fecal lactic acid bacteria in probiotic E. faecium IS-27526 group as well as probiotic E. faecium IS-27526 and fish oil group increased significantly (p < 0.05) as compared to the control group. The fecal coliform bacteria in probiotic E. faecium IS-27526 and fish oil group decreased significantly (p < 0.05) as compared to the control as well as probiotic E. faecium groups after 90 days.

Judul: Elektrodeposisi Film Tipis Semikonduktor Cu2ZnSnS4 (CZTS) pada Substrat Kaca ITO
Abstrak: Semiconductor Cu2ZnSnS4 (CZTS) thin film that can be used as absorber layers on solar cell module was made via electrodeposition method. CZTS thin film was electrodeposited on the surface of a silicate glass coated with a thin layer of indium tin oxide (ITO). Deposition process was done using potentiostatic mode at room temperature with a potential of 1.05 V for 30, 45, and 60 minutes, followed with annealing the film at 2 different temperatures, 500 ºC using furnace and 180 ºC using hot plate, both treatments for 45 minutes in N2/H2S atmosphere. The X-ray difractograms were analyzed using Match 2 program and showed that the CZTS thin films had kesterit crystalline structure, with a low percentage of CZTS phase. The thin film also contained secondary phases such as Cu2S, ZnS, and SnS. The obtained CZTS thin films had a thickness between 1.039 and 1.676 μm. Absorption study showed that the band gap energy of CZTS thin films which was annealed using furnace ranged from 1.50 to 1.52 eV, whereas that annealed using the hot plate was not observed. The band gap energy value showed that CZTS thin films can be used as sunlight absorber layers on solar cell. The formation of CZTS crystal film on this investigation was effectively performed using furnace annealing process at a temperature of 500 ºC with deposition time of 45 minutes.
