Abstract

Global warming has an impact on the decline in the quality of human life, as a result of the decline in the quality of the environment. To prevent and overcome these problems, an effort is needed, one of which is to produce an environmentally friendly product. Investment in environmentally friendly products is becoming an interesting trend as an effort to develop and use environmentally friendly products, one of which is green souvenirs. Green souvenirs can be a product solution to promote an environmentally friendly lifestyle with innovative products that come from the waste of daily living activities. One of them is used cooking oil. This product-based community service activity was carried out in Kayee Lee, Aceh Besar. This activity aims to produce green souvenir products. Education and promotion of environmentally friendly lifestyles for the community contribute to improving the quality of the environment. Activities that have been carried out in the form of socialization, and technical training in the process of making green souvenirs. The results of the service of the partner group have an understanding of the benefits of processing used cooking oil into green souvenirs. The training activities that have been carried out have produced green souvenir products in very varied shapes, colors, and motifs with an attractive appearance so that they are economically viable. Green souvenir product motifs can be customized for events such as seminars, graduations, birthdays, weddings, and decorative or household purposes. Green souvenir products that are expected to open up opportunities for business partners to increase family income also contribute to the environment and health.

Abstract

Jamblang (Syzygium cumini L. Skeels) contains antibacterial compounds and can be formulated into an emulgel form. This study aimed to determine the optimal concentration of ethanolic extract from jamblang seeds, develop emulgel formulations, and evaluate their antibacterial activity against Staphylococcus aureus and Staphylococcus epidermidis. The extraction was performed using 96% ethanol through maceration, followed by phytochemical screening and antibacterial testing using the well diffusion method. Phytochemical screening indicated the presence of alkaloids, flavonoids, saponins, tannins, and triterpenoids. Antibacterial testing of jamblang seed extract against S. aureus and S. epidermidis at various concentrations demonstrated significant inhibition. The emulgel formulations were prepared using jamblang seed extract at concentrations of 5%, 10%, and 15%, with 3% HPMC as the gelling agent. The emulgel exhibited strong antibacterial activity, with the largest inhibition zones observed in the 15% formulation (F3), measuring 21.44 ± 0.21 mm against S. aureus and 19.02 ± 0.60 mm against S. epidermidis. Stability tests showed that the organoleptic properties and homogeneity remained stable. The pH, viscosity, adhesion, and spreadability tests met the criteria for quality preparations, and irritation tests showed no adverse skin reactions. Analysis of variance (ANOVA), followed by Tukey's post-hoc test, indicated significant differences (p < 0.05) in antibacterial activity among all emulgel formulations. In conclusion, Formula F3 (15% extract) showed the best antibacterial activity and met all physical evaluation parameters, confirming that the jamblang seed emulgel is a high-quality and safe formulation. A paired t-test showed all parameters were statistically significant (p > 0.05).
