Biodiversity in Indonesia is the second highest in the world, the medicinal plants are included in it that must be preserved because of their great benefits for a human being life. Ethnomedicine exploration is a bright way that can be done to record and preserve the biodiversity of medicinal plants in Indonesia. The society in Cihanjuang Village still use medicinal plants to treat digestive disorders, but the lack of documentation will eliminate this knowledge in the future. This ethnomedicine study aims to determine plants which used as diarrhea and ulcer drugs in Cihanjuang Village, consisting of the name, the plant part used, the research method used, and identification of  the secondary metabolites. The research methodology used are interview methods with questionnaires, observation, documentation, calculation of Use Value (UV) analysis and phytochemical screening. The informant selection technique used purposive and snowball sampling. The result of this study was the discovery of 24 species of medicinal plants to treat digestive disorders in Cihanjuang Village, most of which belonged to the family of Zingiberaceae and the leaves were the most widely used. The highest of UV’s value for diarrhea is Salak plants (Salacca zalacca) and for ulcers is Hanjuang (Dracaena sanderiana). Some of the species tested for phytochemical screening showed various secondary metabolites that were efficacious in treating digestive disorders. Areuy tulungpung is one of the species that can be studied further due to lack of information as a medicinal plant for digestive disorders.

The environmet's condition as a place for humans and other living things is decreasing due to human activities. To overcome or delay that phenomenon, an eco-friendly lifestyle needs to be applied by everyone. This lifestyle is known as the green lifestyle or sustainable lifestyle. This community service activity aimed to introduce that lifestyle to the women of Aisyiyah local administrations (PDA) of North Jakarta. In this workshop, the lecturers of the Faculty of Pharmacy, Universitas Muhammadiyah Prof. DR. HAMKA gave the lecture about how to utilize and minimalize waste from household activity which is very useful in the pandemic era, when most of the family spent their activities at home. The main theme of this workshop is less-waste lifestyle, vegetable regrow from cooking waste and also the utilization of used cooking oil for making eco-friendly soap. Because of the pandemic situation, this workshop was held on the 2nd of January 2021 with web seminar method using Zoom meeting and the coordination was performed by WhatsApp group. Aside from PowerPoint slides and videos of eco-friendly soap making, the participant was given a post-test and an evaluation form at the end of the webinar. The duration of this webinar was 2 hours and the follow-up were carried out in the WAG, which is monitoring the participant's regrow results. From this activity, the post-test result showed that participants obtained an upgraded knowledge about the lecture given.

Allium cepa L. (onion bulb) is a cultivated onion extensively and types of onions that are often used for various cuisines in Indonesia. The onion bulb was efficient in reducing blood fat levels and diuretics. This study aims to complete the onion monograph with determine the physicochemical characteristics and antioxidant activity. Microscopic results obtained include: has fibrous roots and it’s white, and about 9.5 cm long. The stem is pseudo, and the water is whitish-green, cylindrical leaves are dark green, elongated like a pipe and hollow with a length of ± 20 cm, and the tip is tapered. Onion tubers are single layer bulbs, having a diameter of 6 mm, which is higher than onions. Microscopic results contained identification fragments, including hair covering and transporting beams with thickening stairs and spirals. From the results of research on ethanol extract, 70% Allium cepa L. shows a drying shrinkage of 9.69%, 5.16% total ash content, 0.07 % acid insoluble acid dust, 14.36% water-soluble extract, and soluble ethanol extracts 23.04%. Phytochemical screening contains flavonoids, saponins, phenols, dan triterpenoids. Total flavonoid content contained in ethanol extract of onion tubers was 1.48 ± 0.12 mg QE/g. Total phenolic concentrations obtained in onion tuber ethanol extract were 103.47 ± 3.09 mg GAE/g. The antioxidant activity of ethanol extract of onion tubers by the DPPH method received IC50 is 65.31 ppm.
