Peternak domba umumnya memelihara domba dengan cara melepaskan dan membiarkan ternaknya untuk merumput secara liar, sehingga domba mendapat asupan pakan dengan nutrisi yang tidak seimbang. Salah satu program mahasiswa dalam kegiatan kuliah kerja nyata tematik Institut Pertanian Bogor (KKN-T IPB) di Desa Pantai Mekar, Kecamatan Muara Gembong, Kabupaten Bekasi yaitu pemeriksaan kondisi fisik, sosialisasi manajemen pemeliharaan domba serta distribusi vitamin B kompleks yang bertujuan meningkatkan kesehatan ternak domba. Telah dilaporkan kematian empat ekor domba oleh salah satu peternak setelah pemberian vitamin B kompleks selama empat hari. Kadaver domba dibawa ke Sekolah Kedokteran Hewan dan Biomedis, IPB untuk dilakukan bedah bangkai atau nekropsi untuk mengungkap penyebab kematian. Hasil bedah bangkai, ditemukan infestasi cacing Haemonchus contortus pada abomasum domba, disertai dengan penumpukan cairan pada bawah kulit, rongga dada, perut, serta paru-paru. Penyebab kematian keempat domba berdasarkan bedah bangkai disebabkan oleh infestasi parah cacing jenis Haemonchus contortus dan malnutrisi, yang menyebabkan hipoalbuminemia serta berlanjut menjadi edema pada paru-paru, yang berakibat sesak nafas (dyspnea). Pada kasus ini hasil nekropsi menunjukkan bahwa pemberian vitamin B kompleks bukan menjadi penyebab kematian pada domba-domba tersebut.

Damage to cells caused by stress can be reduced by the presence of antioxidants, one of which is Superoxide dismutase (SOD). The role of the active ingredients of black tea and turmeric will be studied using the in-silico method to identify the active compounds as components in SOD activation. The bioavailability and toxicity of the active compounds of black tea and turmeric were studied and followed by molecular docking and virtual games. The parameters studied are Gibbs's free energy (∆G) and binding site similarity (BSS). The results were analyzed using Gibbs's free energy (∆G) and binding site similarity (BSS) parameters. It was found that those that could increase the activity of Cu/Zn SOD enzymes were Epicatechin gallate (black tea) and curcumin (turmeric), with values ​​of -9.5 and -7.4 Kcal/mol and the same BSS value of 81.8%. The control ligand used was beta amyrin. According to Lipinski's rules, Epicatechin gallate and curcumin compounds can be absorbed well and are safe for consumption. This study concludes that Epicatechin gallate, an active compound of black tea, and curcumin, an active compound of turmeric rhizome, have the best potential to increase the activity of Cu/Zn SOD enzymes based on the results of virtual screening and molecular docking. Epicatechin gallate and curcumin are predicted to be well absorbed by the body because they qualify Lipinski's rules and are not toxic and safe for consumption.

This study aimed to isolate the endophytic fungi of soursop leaves that have the potential as anti-yeast. Soursop leaves were collected from 3 locations in West Java, Indonesia. The secondary metabolites produced by the endophytic fungi were extracted with ethyl acetate and tested for anti-yeast activity against Saccharomyces cerevisiae and Candida tropicalis. Profile of extracts contents characterization was carried out by using thin-layer chromatography (TLC). Twelve monoculture soursop leaves endophytic fungi isolates from Sukabumi (3 isolates), Cianjur (3 isolates), and Garut (6 isolates). It showed different abilities to inhibit C. tropicalis and S. cereviseae. The best extract is isolat from Cianjur (Sir-C1) and Sukabumi (Sir-S1). The stain patterns seen between the nine endophytic fungi extracts were similar. This indicates that the compounds in them may also be the same. But the extracts have a different absorbance for anti-yeast activities. This indicates that the total metabolites of each isolate are different. TLC results showed that ethyl acetate extraction produced almost the same metabolite components from nine endophytic fungi extracts, and all extracts had an anti-yeast activity with various absorbance. There are differences in the ability of 12 soursop leaf endophytic fungi to inhibit yeast model C. tropicalis and S. cerevisiae. Some extracts have similar TLC profiles, but their anti-yeast activity is not similar

The use of antibiotics as an Antimicrobial Growth Promoter (AGP) for livestock has been banned because antibiotic residues in livestock meat can trigger antibiotic resistance in consumers. Propolis is a natural source that has benefits like antioxidants, antiviral, antifungal, and antibiotic. The purpose of this study was to determine the effectiveness of the addition of feed from the optimal composition of raw propolis to increasing broiler chickens' body weight of broiler chickens. This study used broiler chickens as experimental animals. The chicken were grouped into six groups consisting of two control groups and four treatment groups with different level concentrations of propolis (2, 4, 6, and 8 g/kg feed). After treatment for four weeks, supplementation of raw propolis in the feed had not been able to provide a positive effect on growth performance and protein levels that were not significantly different from controls. Group chickens with propolis additions 6 g/kg feed showed the best results compared to other treatment groups. The group had final weight values, food conversion ratio (FCR), and carcass weight in 1970.67 gram, 1.52, and 1349.83 gram, respectively. The highest percentage of the carcass was shown by group chicken with propolis additions 2 g/kg feed, which is equal to 74.46%. Raw propolis can reduce feed consumption but increase feed conversion ratio.

Biosurfactant is secondary metabolite surface active compound produced by microorganisms which is nontoxic and eco-friendly. Microorganism producing biosurfactant that is quite potential to use in many applications is from Pseudomonas aeruginosa strains. Good quality of biosurfactant production from microbes is supported by the suitable nutrients and environmental factors. The aim of this research was to obtain preliminary o data upon the optimum pH and salinity for the production of biosurfactant from Pseudomonas aeruginosa ATCC 15442 in diesel fuel and crude oil medium. P. aeruginosa ATCC 15442 cultured in diesel fuel and crude oil as carbon source showed biosurfactant activity. P.aeruginosa-derived biosurfactant was capable to form stable emulsion for 24 hours (EI24) in hydrocarbons n-hexane solutions. The particular biosurfactant showed EI24 highest value at pH 7 (31.02%) and 1% NaCl (24.00%) when P. aeruginosa was grown in 10% diesel fuel medium in mineral salt solution. As for the media crude oil, the highest EI24 value was at pH 6 (52.16%) and 1% NaCl (33.30%).

Propolis is a resinous substance collected by stingless bee or honey bee from various plant sources. The substance is known to contain beneficial properties for human. The geographical origin of propolis determines its biological properties. In this study, propolis were collected from five regions of Indonesia with the objective of determining the yield, their total flavonoid content, their capacity to induce apoptosis, and their toxicity to the Michigan Cancer Foundation-7 (MCF-7) cell line. The inhibition of antioxidant 1,1-diphenyl-2-picrylhydrazyl (DPPH), the induction of apoptosis to Saccharomyces cerevisiae and the anticytotoxic ability were determined. Propolis from Pekanbaru region had higher yield than other regions with value of 19.97%; propolis from Kendal had higher quantity with value of 46.60%, total flavonoid content; propolis from Pandeglang was higher in DPPH oxidation capacity with value of 68.94 ?g.ml-1; propolis from Kendal, expressed petite cell induction in S. cerevisiae cells with value of 81.44%, and the anticytotoxic to MCF-7 breast cancer cell line were best observed in propolis from Makassar region with a value of 47.71% life cells. All of the propolis extracted from the stingless bee hive Trigona spp from five regions in Indonesia contained flavonoids.

Coconut has been known to have many advantageous effects on human health and can be used to prevent and protect human body from oxidative damage. The aim of this research was to determine the effect of kopyor coconut and virgin coconut oil (VCO) on cellular defense mechanism against oxidative damage by ethanol stress 17.5% (v/v). The effect of kopyor coconut and VCO addition was analyzed by observing viability of yeast cells (Candida sp. Y 390) that had been given ethanol stress. In addition, acitivity of superoxide dismutase (SOD) was also measured. Results showed that addition of kopyor coconut and VCO into growth medium at early incubation stage increased viability of yeast cells under ethanol stress. SOD activity of yeast cells grown on medium containing kopyor coconut or VCO was found to significantly increase. SOD activity of Candida sp. Y 390 that given 0.84 g kopyor coconut, 37 ?L VCO and 74 ?L VCO was 135.66, 122.26 and 157.97 U/mg protein respectively. It was found that activity of MnSOD was higher compared to CuZnSOD enzyme. These results suggest that addition of kopyor coconut and VCO triggers Candida sp. Y 390 resistance to ethanol stress by induction of MnSOD activity.
