Stingless bee propolis (Heterotrigonaitama) is often disregard by beekeeper when it<br />

may have valuable antifungal properties in it. The objective of this study is to test the<br />

antifungal effect of stingless bee propolisaqueous extraction as a fruit coating on<br />

reducing anthracnose while maintaining the postharvest quality of tomato. There are<br />

six treatments including positive control and negative control were assessed in this<br />

experiment.There was no significant difference incolour, pH level, total soluble solid,<br />

citric acid level and weight loss except for lycopene content which highest in treatment<br />

5 (8%). In the firmness analysis, treatment 6 (10%) is higher than the rest of the<br />

treatment with the value of 0.402 (p>0.05). Treatment 6 (10%) shows the least<br />

disease severity according to the disease severity index. Therefore, based on the<br />

analysis, coating contained 10 % of stingless bee propoliscan maintained the postharvest<br />

quality of tomato.<br />
