Sweet potato is a good food ingredient, because of its starch which has a very rich nutritional content, including high carbohydrates. Therefore, in some areas sweet potato is also used as a staple food. It also contains protein, vitamin C and is rich in vitamin A (β-carotene). β-carotene in yellow sweet potato (Ipomoea batatas L.) can function to meet the needs of vitamin A and as an antioxidant in reducing the effects of free radicals. The purpose of this study was to determine the differences in β-carotene levels in raw and boiled yellow sweet potato (Ipomoea batatas L.) using the UV-Vis spectrophotometry method. Samples of yellow sweet potato were extracted by using maceration method with 95% ethanol solvent. Then a quantitative analysis was performed using the UV-Vis spectrophotometry method at a wavelength of 450 nm and a linear regression equation was obtained y = 0.0237x + 0.395 and a correlation coefficient (r) of 0.9931 and an average level of β-carotene in raw yellow sweet potato was obtained of 1278 .23 mg/kg and boiled yellow sweet potato of 413.90 mg/kg. So from this study it can be concluded that the levels of β-carotene in raw yellow sweet potatoes are greater than boiled yellow sweet potatoes because some boiled yellow sweet potatoes have been damaged due to heat or dissolved / lost to water.

Cat's whiskers leaf plant (Ortosiphon aristatues.) is one of the plants that is efficacious as a medicinal plant. The part of the cat's whiskers leaf plant is used, namely the leaves that contain saponin compounds, flavonoids, alkaloids and tannins. The purpose of this study was to determine the most effective inhibition produced by the ethanol extract of the leaves of the cat's whiskers (Ortosiphon aristatues.) against the growth of Staphyloccocus aureus bacteria. The benefit of this research is to increase knowledge about the antimicrobial potential of ethanol extract of cat whiskers (Ortosiphon arietatus) leaves against the growth of Staphyloccocus aureus bacteria. This research method uses the diffusion method for wells. The sample used was cat whiskers leaf extract with pure strain of Staphyloccocus aureus. Treatment with cat whiskers leaf extract, the results of the test of the inhibitory activity of the cat whiskers leaf extract showed an average difference at a concentration of 65% with a diameter of 22 mm, a concentration of 70% with a diameter of 25 mm, and a concentration of 75% with a diameter of 30 mm. Ethanol extract of cat whiskers leaves with a concentration of 65%, 70%, and 75% effectiveness in inhibiting the growth of Staphylococcus aureus bacteria. Based on observations, it was shown that the ethanolic extract of Kumis Kucing leaves gave the most effective inhibitory concentration at a concentration of 75% against Staphyloccocus aureus bacteria. with a diameter of 30 mm

Information technology can be used in various human lives, one of which is in the business field. In today's era, it is undeniable that computers with accounting information system equipment are components that must be owned by companies to help ease the task of company performance. One of them is BKM which is specifically aimed at poverty alleviation and community development. UPK itself is a non-profit organization or an organization whose main objective is to support an issue or matter in attracting public attention for a non-commercial purpose, without any attention to things that are for-profit. The allocation has also been divided according to their respective portions.
This study aims to simplify the presentation of profit budgeting at BKM which is still not structured and does not provide clarity about the results of the funds that should be used as the allocation of community activities. Profit budgeting is also not carried out periodically and is still manual in recording so that profits cannot be known in detail. In overcoming the problems above, by using a programmed system with the a posteriori method, the institution can easily record every operational budget to the profit budget so that it can allocate funds for community activities in a structured manner

Telang flower has the potential to inhibit the growth of Candida albicans, Malasezia furfur, Pitosporum ovale, and Aspergilus fumigatus through the kombucha fermentation biotechnology method. The purpose of this study was to determine the antifungal activity of telang flower kombucha at various concentrations of white sugar. The varying concentrations of granulated sugar used in this study were 20%, 30%, and 40% (w/v), each repeated 3 times. The positive control used was kombucha made from green tea. The negative control used was sterile distilled water. The well diffusion method is one of the methods used to test antifungal activity. The fementation of telang flower kombucha has overall antifungal activity. White sugar concentration of 40% kombucha telang flower was the best concentration in inhibiting the growth of fungi as a whole when compared to the concentration of white sugar kombucha telang flower of 20%, 30% and positive and negative controls.
