Abstract

Pesticides are often used to control pests and improve the quality of agricultural products such as vegetables. However, excessive use of pesticides can leave residues on vegetables, which can harm the environment and human health. In addition, the Indonesian government's ban on using harmful pesticides on vegetables and the health risks associated with eating pesticide-contaminated food. Then strategies to manage pesticide residues, such as the use of organic fertilizers as pesticide substitutes, standardization of maximum limits of pesticide residues, monitoring pesticide residues, encouraging the use of pesticides separately, and training farmers. The conclusion in pesticide residues on vegetables is how important it is to manage pesticide residues on vegetables to maintain public safety and health.

Abstract

This study was conducted to determine the secondary metabolite compounds and evaluate the antimicrobial activity of ethanol extract of jamblang stem bark (Syzygium cumini). The method used in this research is experimental method. The extraction was carried out using the maceration method with 96% ethanol as the solvent. Secondary metabolite compounds of the extract samples were analyzed using a Gas Chromatography-Mass Spectrometry (GC-MS). Antimicrobial activity of the extract against Cutibacterium acnes, Staphylococcus aureus, and Candida albicans using disc diffusion method tested on MHA (Mueller Hinton Agar) media with extract concentrations of 40%, 60%, 80%, and 100%.  Each experiment was repeated three times to ensure validity. The results revealed that the extract have dominant compounds such as 7-Tetradecenal (Z), Octadecanoic acid, and n-Hexadecanoic acid. The antimicrobial test showed that the highest inhibition zones were 7.45 mm for C. acnes, 8.04 mm for S. aureus, and 4.60 mm for C. albicans at 100% extract concentration. The inhibition zones increased with higher extract concentrations, indicating a dose-dependent relationship. Compared to the positive control results (20.70 mm; 22.29 mm; and 18.62 mm) the extract showed moderate antimicrobial activity. These findings suggest that jamblang stem bark extract has potential as a natural antimicrobial agent.
