Abstract

Ethanol from sago flour through fermentation using Saccharomyces cerevisiae and gelatin as nutrition for microbe have been done. The making of ethanol through processes of hydrolysis, fermentation, distillation and analysis of ethanol concentration using Gas Chromatography instrument. The hydrolysis process of sago flour are used two steps which is liquification and saccharification using alpha-amylase and glucoamylase which will convert the starch into glucose. The fermentation process of glucose are done with time variation 5, 6, 7 and 8 days to the concentration variation of gelatin addition which is 0,5 %, 1 % and 1,5 % (w/v) as nutrition source for microbe. The obtained ethanol from fermentation process are purified through distillation. Furthermore, analysis of ethanol concentration are used Gas Chromatography. The analysis results are showed the highest ethanol concentration obtained in 7 days with gelatin addition 1,5 % are 79,50 %.

Abstract

Antihyperuricemia activity tests were conducted on an ethanol extract of green leaf plant red bud (Syzygium myrtifolium Walp.). Hyperuricemia is a condition in which uric acid levels in the blood increases due to the consumption of high purine is converted into uric acid. Antihyperuricemia activity test ethanol extract of green leaf plant red bud (Syzygium myrtifolium Walp.) Conducted on male white mice with a variety of doses of 1.85, 3.7 and 7.4 mg/kg. Extract dose of 7.4 mg/kg dose is the closest percentage drop on allopurinol which lowers blood uric acid levels at 55.04 %. Phytochemical screening showed that the green leaf plant red bud contains alkaloids, triterpenoids, steroids, phenolics, flavonoids and saponins. These results indicate that the ethanol extract of green leaf plant red bud has antihyperuricemia activity.

Abstract

“Jarum Tujuh Bilah” leaves (Pereskia bleo (Kunth) DC) are a medicinal plant that often used in traditional medicine to reduce uric acid levels. This plant contains secondary metabolites which have the potential to inhibit xanthine oxidase activity. In this study phytochemical tests were conducted on ethanol extract and ethyl acetate fraction of “Jarum Tujuh Bilah” leaves (Pereskia bleo (Kunth) DC), then isolated xanthine oxidase from fresh cow's milk, and the activity of ethyl acetate fraction against xanthine oxidase. The results showed that ethanol extract contained flavonoid, alkaloid and phenolic compounds. Then ethyl acetate fraction contained flavonoid and alkaloid compounds. The value of xanthine oxidase activity from the isolation of xanthine oxidase is 0.00063 U/mL in the fractionated enzyme and 0.00025 U/mL in the supernatant. The inhibition of 92.06% ethanol extract and the inhibition of ethyl acetate fraction was 88.89%.

Abstract

Desa Teluk Tempudau, yang terletak di tepi Sungai Mahakam, sangat bergantung pada sumber daya hayati sungai, termasuk ikan gabus (Channa striata). Ikan ini memiliki adaptasi yang luar biasa dan menjadi sumber pangan serta potensi usaha bagi masyarakat. Namun, pengetahuan dan keterampilan dalam pengolahan ikan gabus masih rendah, sehingga kelompok KKN Universitas Mulawarman melakukan sosialisasi dan pelatihan pembuatan abon ikan haruan. Kegiatan ini bertujuan untuk meningkatkan diversifikasi produk dan membuka lapangan kerja di desa. Pelatihan meliputi sosialisasi tentang UMKM, potensi ekonomi ikan haruan, pemasaran digital, dan praktik pembuatan abon. Kegiatan dilaksanakan pada 7 Agustus 2024, melibatkan masyarakat setempat, terutama pemuda, untuk meningkatkan keterampilan dan pengetahuan dalam mengolah ikan haruan. Diharapkan, masyarakat dapat mengembangkan produk olahan ikan gabus, selain ikan asin, untuk meningkatkan kesejahteraan.

Abstract

The use of chitosan from maggot (Hermetia illucens) exuvia as an edible coating for tomatoes (Lycopersicon esculentum) and an edible film with honey added as an antibacterial agent was investigated. This study aimed to determine the yield of chitosan from black soldier fly (BSF, Hermetia illucens) maggot exuviae as an edible coating. The chitosan was produced from chitin by deacetylation, and its effect on the weight loss and vitamin C levels of tomatoes for 7 days after treatment was investigated. The chitosan coating was characterized by scanning electron microscopy (SEM) and Fourier transform infrared spectroscopy. The antibacterial activity was evaluated using a disk diffusion method. The result showed that by deacetylation, conversion of chitin produced chitosan with a yield of 72% and a deacetylation degree of 75.05%. The chitosan coating significantly affected the weight loss of tomatoes, with the best concentration being 2%. However, the treatment did not significantly affect the decrease in vitamin C levels. The edible chitosan film from BSF maggot exuviae with added honey had a thickness, water content, and water vapor transmission rate of 0.156 mm, 16.9913%, and 30.45 g/m2/24 hours, respectively. SEM characterization showed a relatively dense surface structure, which was slightly smooth and porous. Regarding antibacterial activity, the edible chitosan film inhibited Staphylococcus aureus with an inhibition zone of 10.37 mm; however, Escherichia coli was not inhibited. These results suggest that chitosan from BSF maggot exuviae has potential as an effective edible coating for reducing weight loss in tomatoes despite showing limited antibacterial properties.
