Abstract

The World Health Organization has designated Covid-19 as a pandemic that causes activities outside the home to be restricted. In order to maintain health during the pandemic, many people are starting to choose foodstuffs produced from organic farming. The purpose of this activity is to provide information and motivation to society for reuse household waste with appropriate technology to produce compost. This service activity was carried out in Air Dingin Village, Bukit Raya District, Pekanbaru. The initial stage conveys material about the importance of maintaining health during the pandemic by consuming organic vegetables and fruits grown in their respective yards. Furthermore, the practice of making compost using the direct-use compost method and composting in a composter pot. Composting that reuses household waste has succeeded in opening up insight into the importance of the community's role in personal and environmental health and the public's understanding that a healthy life doesn't have to be expensive. In this activity, the participants showed their enthusiasm and stated that they would practice and share their knowledge with others in making compost to overcome the problem of household waste. This activity is also beneficial to keep the environment clean, healthy and beautiful.

Abstract

Plants are the main medicinal source that exists around the world, due to the content of bioactive compounds such as flavonoids, alkaloids, saponins, polyphenols, tannins, terpenoids, and essential oils. These bioactive compounds have antimicrobial activity. The purpose of this study was to analyze the antibacterial activity of a combination extracts of Sumatran wild mango (M. sumatrana, and M. foetida var. Batu), R. tuberosa L.  and Leucobryum sp. against bacteria that cause gangrene wounds in diabetics. Preparation of plant extraction is carried out by the method of maceration using 70% alcohol. Testing of antibacterial activity using the disc paper method 6 mm in diameter at an extract concentration of 10% with seven treatments (P1-P7). The test results obtained the largest inhibitory zone diameter against Staphyococcus aureus ATCC 6538 and S. epidermidis ATCC 12228 both shown in combination II extracts at P7 treatment (2:3:1 ratio), 9.04±1.42 mm and 8.85±0.21 mm, respectively. The results of the inhibitory zone resulting from the combination extract test included criteria of resistance to Staphylococcus. In the positive control, the diameter of the chloramphenicol inhibition zone against S. aureus belongs to the sensitive category, but to S. epidermidis it belongs to the resistant category. Combination of methanol extract from wild mango, R. tuberosa L and Leucobryum sp. has the opportunity as the candidate for natural-based antibiotics to replace synthetic antibiotics.
