Abstract

The aim of this research is to identify the antibacterial activity of Bridelia micranth Lombok extract on the pathogenic bacteria Escherichia coli. The independent variable in this study was the concentration of Bridelia micrantha leaf extract. The concentration of Bridelia micrantha leaf extract in this study was varied from 20%, 40%, 60%, and 80%. The dependent variable is the ability of Bridelia micrantha leaf extract as an antibacterial. The antibacterial ability of Bridelia micrantha leaf extract was measured based on the diameter of the clear zone with three repetitions. As a comparison, an antibacterial is used, namely amoxicillin. Data analysis in this research was carried out descriptively, and then non-parametric tests were carried out to test the homogeneity of the data. In this study, the antibacterial ability of Bridelia micrantha leaf extract was discovered. At a concentration of 20%, the average diameter of the inhibitory zone was 2.5 mm which was categorized as none (resistance), 40% concentration was 9.83 mm in the non-existent category (resistance), 60% concentration was 13.66 in the weak category (intermediate), and at a concentration of 80% 16.5 mm is in the medium (sensitive) category. The research results indicated that Bridelia micrantha leaf extract had antibacterial activity against Escherichia coli bacteria. When compared with amoxicillin, the ability of Bridelia micrantha leaf extract as an antibacterial is still lower. Amoxicillin was able to inhibit the growth of Escherichia coli by 18.13 mm, while the highest ability of Bridelia micrantha leaf extract was 16.5 mm. Based on Ministry of Health regulations, antibacterials can be used if the inhibition zone is between 14-18 mm. So, Bridelia micrantha leaf extract can be used as an antibacterial, but it needs to be tested further before being applied to the public.

Turning Waste into Blessings: Training on Processing Organic Waste as a Media for Cultivating Organic Mushrooms and Vegetables Abstract This service aims to train partners to utilize organic waste straw, sago dregs and sawdust as a growing medium for straw mushrooms. Next, the mushroom waste is processed as a vegetable growing medium. The main problem faced by partners is that they have not been able to utilize organic waste into materials that have economic value. The technique used in this community empowerment activity is PRA (Participatory Rural Appraisal) where the implementation involves the local community in all activities and local stakeholders. The advantage of this method is that it can improve the skills of partners because they are directly involved in the straw mushroom production process. The aim of using this technique is so that people can share and increase their knowledge about the conditions and life of the community, make plans and act. The success of the service process is assessed from the partner's competency in cultivating mushrooms and vegetables from straw mushroom waste. Partners have been able to cultivate straw mushrooms and vegetables as proven by the excellent mushroom harvest. Vegetables also grow well on mushroom waste media when compared to soil media. The temperature that is kept stable in micro barns has been proven to be able to increase production by 5 kg per shelf. If taken as a whole, there was a 10% increase in production compared to the size of the kumbung usually used by straw mushroom farmers. Based on the harvest results and trials of chili plants on straw mushroom waste, it can be concluded that the people of Bengkaung village have been able to use organic waste as a growing medium for straw mushrooms and are able to use mushroom waste as a medium for growing vegetables.

Abstract

The increasing global prevalence of oxidative stress-related diseases such as cardiovascular disease, diabetes, and neurodegenerative disorders underscores the importance of developing effective antioxidant strategies. In this study, samples of ethanol extract from Bridelia micrantha (Melandean) leaves were used which were then evaluated using the DPPH (2,2-diphenyl-1-picrylhydrazyl) test, a method that is widely known for assessing free radical scavenging activity. The ethanol extract sample was obtained through maceration with a yield of 15.84%. Based on the DPPH test, it shows that the extract has dose-dependent inhibition of DPPH radicals, with a maximum inhibition of 66.13% at a concentration of 25 ppm. The IC50 value, calculated from regression analysis, confirmed the antioxidant potential of the extract, although it was less effective than that of vitamin C, which was used as a positive control. These findings suggest that Bridelia micrantha leaves, rich in phytochemicals such as flavonoids, tannins, and saponins, have the potential as a source of natural antioxidants for managing oxidative stress-related health conditions.
