Abstract

The Bajakah tampala tree (Spatholobus littoral hassk) is a native plant from the interior of the forests in Kalimantan, especially Central Kalimantan. This plant is a plant that stretches or grows and grows abundantly in the interior of the forest. The Bajakah plant is known to the people of Kalimantan as a medicinal plant and can cure various diseases, including diarrhea, rheumatism, and cancer. The aim of this research was to determine the alkaloid content of bajakah root extract in various concentrations. The research method was carried out experimentally, with the independent variable being an ethanol extract of bajakah roots with concentrations of 50, 70, and 96%. Meanwhile, the dependent variables are the characteristics of simplicia, the secondary metabolite content of Bajakah root ethanol extract, and the determination of the total alkaloid content of Bajakah root extract. Bajakah root simplicia extract is made with 96, 70, and 50% ethanol solvents. The parameters used in this study include water content, total ash content, acid insoluble ash content, water soluble extract content, ethanol soluble extract content, and secondary metabolite content, including alkaloids, tannins, flavonoids, saponins, steroids, and terpenoids, by conducting phytochemical screening. , making a standard caffeine solution, determining the maximum wavelength of caffeine, measuring the caffeine calibration curve, and determining the total alkaloid content of Bajakah root extract. The results of the phytochemical screening showed that Bajakah root was positive for containing alkaloid compounds, saponins, tannins, flavonoids, steroids, and terpenoids. And the results obtained from Bajakah root plants obtained from Central Kalimantan were a 96% ethanol concentration of 1.66797 ± 0.7088 mg/gram, a 70% ethanol concentration of 1.6679 ± 0.1124 mg/gram, and a 50% ethanol concentration of 0.46981 ± 1.0656 mg/gram

Abstract

Secondary metabolites with antibacterial properties have been found in arummanis mango leaves. Alkaloids, flavonoids, tannins, saponins, triterpenoids, and steroids, especially the mangiferin molecule found in several mango varieties, are also present in arum manis mango leaf extract. Mangiferin has shown action on Staphylococcus aureus as an antibacterial agent that can prevent the development of bacteria. Staphylococcus aureus is one of the bacteria that triggers skin infections. In this research, extract nanoparticles and inhibition tests against staphylococcus aureus bacteria were prepared using extract nanoparticles and ethanol extract of arum manis mango leaves. The manufacture of nanoparticles in this study was carried out because smaller and nanometer-sized materials have more special chemical and glass characteristics; their small size has a greater surface area to volume ratio than larger particles. Nanoparticles are small particles ranging in size from 1 to 1000 nm. A particle size analyzer is used to characterize nanoparticles. Using the disc diffusion method, antibacterial activity tests were carried out at concentrations of 25%, 50%, and 75%, using nanoparticle extracts, and 2.5%, 5%, and 7.5% for extract concentration. The results of the extract nanoparticle size characterization were 40.2 nm. The bacterial inhibition zones of arum manis mango leaf extract obtained at concentrations of 25%, 50%, and 75% were 11.9, 14.4, and 15.4 mm, respectively. Meanwhile, the inhibition zones of nanoparticle bacteria extract 2.5%, 5%, and 7.5% were 15.5, 17.5, and 18.3 mm, respectively. The concentration of 2.5% nanoparticle extract has the inhibition power of bacteria equivalent to that of 75% ethanol extract, so it says that the nanoparticles can reduce the size dose and have an inhibition power in the moderate sensitivity category.

Abstract

Single Cell Protein (PST) is the term used for proteins derived from microbes such as fungi, yeasts and bacteria. One way to deal with the abundance of tofu liquid waste is by using microbiological methods, namely utilizing tofu liquid waste as a substrate for the growth of Bacillus cereus microbial growth for single cell protein production. The purpose of this study was to determine whether tofu liquid waste could produce single cell protein from B. cereus culture and to determine the difference in protein production by adding nutrients to the fermentation medium. The research method used was experimental research, with the independent variables being MFLT1 fermentation medium (Tofu Liquid Waste Fermentation Medium with the addition of KH2PO4 nutrients and sugar) and MFLT2 medium (Tofu Liquid Waste Fermentation Medium with the addition of nutrients KH2PO4; (NH4)2SO4 and sugar); and the length of fermentation on days 0, 2, 4 and 6. While the dependent variables were the analysis of protein content, cell dry weight, glucose content, pH and temperature. The result data in this study were statistically analyzed using the two way Anova method. The results of this study showed that the highest protein content was obtained in MFLT2 medium, namely 0.73% (day 4); cell dry weight 0.253 g; glucose level 1.3339%; pH 3.9 and temperature 29.2oC. Meanwhile, in MFLT1 medium, the highest protein content was 0.46% (4th day); cell dry weight 0.286 g; glucose level 1.3342%; pH 3.9 and temperature 28.8oC. From the research that has been carried out, it can be concluded that tofu liquid waste can produce single cell protein from B. cereus culture and there are differences in protein production results with the addition of nutrients, where the protein content in MFLT2 medium is higher than protein content in MFLT1 medium.

Abstract

Matoa memiliki sejarah panjang dalam penggunaan obat tradisional (Pometia pinnata J.R. Forst & G. Forst). Antioksidan termasuk vitamin C dan E, serta flavonoid, tanin, dan saponin dapat ditemukan dalam jumlah yang melimpah pada buah matoa. Penelitian ini bertujuan untuk mengetahui sifat antibakteri dari ekstrak etanol serbuk simplisia daun matoa dan metabolit sekundernya terhadap Salmonella thypi. Variabel bebas dalam penelitian ini adalah ekstrak etanol daun matoa (Pometia pinnata J.R. Forst & G. Forst). Pengujian dilakukan pada ekstrak 50%, 30%, dan 30%. Aktivitas antibakteri ekstrak etanol daun matoa ditentukan dari kemampuannya dalam menghambat pertumbuhan Salmonella typhi. Pelarut etanol digunakan untuk menguapkan ekstrak kental yang diperoleh dari hasil maserasi daun matoa. Ekstrak daun matoa diencerkan dengan DMSO 30%, 40%, dan 50%. Pengenceran tersebut akan menentukan seberapa baik ketahanan Salmonella typhi terhadap antibiotik. Metabolit sekunder seperti flavonoid, tanin, alkaloid, saponin, dan steroid dianalisis pada ekstrak etanol daun matoa dan simplisia. Salmonella thypi dihambat dengan rata-rata 12,6 mm pada konsentrasi 30% (Interpretasi menengah), 13,8 mm pada konsentrasi 40%, dan 15,3 mm pada konsentrasi 50% dengan menggunakan ekstrak etanol daun matoa. Aktivitas antibakteri dari ekstrak etanol daun matoa ditunjukkan dengan zona hambat dengan diameter rata-rata daerah hambat yang sesuai dengan interpretasi Intermediate (I).
