Abstract

Gembili tuber (Dioscorea esculenta) is a local tuber crop that has not yet been optimally utilized, despite its potential as a source of bioactive compounds beneficial to human health. This study aimed to evaluate the phytochemical content as well as the antioxidant and prebiotic activities of the ethanol extract of gembili tuber. Phytochemical analysis was conducted to determine the total phenolic, flavonoid, and saponin contents. Antioxidant activity was evaluated using the DPPH method. The results showed that gembili extract contained high levels of phenolic compounds, flavonoids, and saponins, which contributed to its antioxidant activity, with inhibition values and IC₅₀ comparable to the control. The DPPH assay revealed that the antioxidant activity of gembili tuber extract increased with increasing extract concentration. The IC₅₀ value decreased from 116.7 ± 1.7 ppm at 1000 ppm to 76.4 ± 0.8 ppm at 3000 ppm. The results of this study indicate that gembili tubers have the potential to be a source of prebiotics and natural antioxidants that can be developed as locally based functional food ingredients.

Abstract

One of the freshwater fish that has been successfully cultivated by the people of Macang Sakti village is tilapia. However, the high cultivation is not in line with its marketing, which is still relatively low. In addition, high feed costs are also an obstacle to raising tilapia. Therefore, education on innovation in processing tilapia seeds in the form of nutritious food is very necessary to be provided to the community by empowering women's groups as business actors. This effort also aims to increase family economic income. The location of community service was carried out in Macang Sakti Village, Sanga Desa District, Banyuasin Regency, South Sumatra. The methods used were survey methods, counseling, discussion and demonstration (practice) of processing tilapia seeds into crispy babyfish. The implementation of the activity was attended by more than 16 participants from among housewives with great enthusiasm. The results of this Community Service show that community service activities can increase participants' knowledge and skills about nutrition and processing tilapia seeds into healthy snacks (crispy babyfish) and motivate them to actively consume fish.
