The Potential of Coffee Grounds in Enhancing Lanzones (Lansium Domesticum) Peel as Mosquito Coil Repellent

Abstract

This research paper explores the potential of used coffee grounds in enhancing the repellent efficacy of lanzones (Lansium domesticum) peel in the formulation of eco-friendly mosquito coils. To addresses the increasing demand for sustainable control methods amidst the rising dengue cases, this study utilized an experimental design wherein the mosquito coil was formulated using 75% coffee grounds and 25% lanzones peel, and was subjected to standard phytochemical analysis at the Department of Science and Technology (DOST) to determine the presence of bioactive compounds that are known for mosquito-repelling properties. Results showed positive detection for all seven bioactive compounds: sterols, triterpenes, flavonoids, alkaloids, saponins, glycosides, tannins, confirming that the integration of coffee grounds significantly enhanced the chemical composition of the lanzones-based coil thereby suggesting that spent coffee grounds can enhance the repellent properties of Lanzones peel, making the resulting coil an effective alternative mosquito repellent. The study thus confirms the rejection of the null hypothesis and demonstrates the potential of organic waste materials, like lanzones peel, in developing sustainable mosquito control solutions. To advance the study and foster further innovation, future researchers may focus on the appropriate drying and pulverizing of the lanzones peel and used coffee grounds, investigate the use of other binding agents for better stabilization, optimize the use of appropriate molders, conduct assessments that compare the enhanced coils with commercial products, and perform field trials for practical applicability evaluation.
