Abstract

Masalah sampah di Indonesia, termasuk sampah rumah tangga, rumah sakit, dan tempat umum, telah meningkat dan menjadi ancaman serius terhadap lingkungan dan kesehatan masyarakat. Sampah organik, yang menyumbang sekitar 60% dari total sampah, jika tidak dikelola dengan baik, dapat menyebabkan pemanasan global akibat pelepasan gas metana. Untuk mengatasi masalah ini, program pemanfaatan sampah organik sebagai komposter dan ecoenzym dilaksanakan oleh mahasiswa Universitas Riau di Desa Limau Manis. Melalui metode sosialisasi dan demonstrasi, program ini bertujuan untuk meningkatkan kesadaran masyarakat tentang pengelolaan sampah organik, serta memberikan solusi praktis yang mendukung keberlanjutan lingkungan dan kesejahteraan masyarakat. Hasil kegiatan menunjukkan partisipasi aktif masyarakat dalam pembuatan kompos dan ecoenzym, serta peningkatan pemahaman mereka tentang pentingnya pengelolaan sampah organik.

Abstract

Dental caries infection is one of the most common dental health problems caused by Streptococcus mutans bacteria. The use of synthetic antibiotics in the treatment of infection risks causing bacterial resistance, so a safer alternative, natural treatment, is needed. Citronella leaves (Cymbopogon Nardus L.) and lime leaves (Citrus aurantifolia Swingle) contain active compounds such as alkaloids, flavonoids, saponins, and tannins that have antibacterial activity. This study aims to determine the effectiveness of the combination of extracts of the two plants against the growth of Streptococcus mutans. The type of research used is laboratory experimental with Completely Randomized Design, consisting of 5 treatments and 4 repetitions. The antibacterial test was carried out by disc diffusion method using a combination concentration of extracts P1 (2.5%: 7.5%), P2 (12.5%: 5%), and P3 18.75%: 2.5%), negative control (distilled water), and positive control (tetracycline). The test results showed that the P3 produced the best inhibition against Streptococcus mutans with an average inhibition zone of (6.02 ± 0.46) mm and fell into the moderate category. Data analysis using the ANOVA test resulted in a significance value of p = 0.000 (p < 0.05), which indicated there were significant differences between treatments. Further tests using Tukey HSD showed that the P3 was significantly different compared to the other treatments. Thus, the combination of citronella and lime leaf extracts is proven to have potential as a natural antibacterial against the growth of Streptococcus mutans bacteria.
