Abstract

The development of eco-friendly cosmetics using local bioresources like Uncaria gambir Roxb. (gambir) holds strong promise for sustainable innovation. This study formulates and evaluates a catechin-based solid shampoo enriched with purified gambir extract, aiming to enhance product stability. A 14-day storage test was conducted at 20 °C and 40 °C using three types of packaging: translucent plastic, aluminum foil, and amber glass. Visual observations revealed that higher temperatures, especially in translucent plastic, accelerated color degradation due to catechin instability. Amber glass was the most effective in preserving the shampoo’s original color. Further, aqueous stability was assessed through two wet-use simulations: soaking (full immersion in distilled water) and dipping (partial immersion daily over four days). The shampoo maintained physical integrity during both tests, showing no softening or structural deformation. However, water discoloration increased over time, indicating catechin release and oxidation. The extent of browning was influenced by the pH of the water, suggesting that both environmental pH and oxidative exposure affect catechin behavior during use. These results demonstrate the solid shampoo’s physical resilience and moderate color stability under thermal and aqueous stress. While catechin oxidation is unavoidable, its rate can be mitigated through optimal packaging and pH management. The gambir-based solid shampoo shows potential as a natural, environmentally friendly personal care product, although further formulation refinement is needed to improve color retention during storage and use.

Abstract

The development of the creative batik industry in Pesisir Selatan Regency faces challenges regarding production and marketing, particularly within the Jembatan Akar Batik Artisan Group. This community service program aimed to enhance the partners' self-reliance and competitiveness in navigating business competition. Implementation methods included Focus Group Discussions (FGD) for problem mapping, training on motif design and batik coloring techniques, digital marketing mentoring, and the provision of production equipment. The results demonstrated an improvement in the partners' ability to create new batik motif compositions based on local wisdom. The partners were successfully able to rebrand their products and actively manage marketing through Instagram, resulting in expanded market reach and an increased volume of orders from new customers. This community service program proved effective in strengthening the production capacity and marketing strategies of the Jembatan Akar Batik Artisan Group.Keywords: Jembatan Akar Batik, FGD, Product Innovation, Digital Marketing, Community Empowerment.
