Although the B30 biodiesel program has been implemented in Indonesia, studies on higher biodiesel blends (B40 and B50) remain limited. Therefore, this study aimed to evaluate the effects of JME biodiesel blends (B30, B40, and B50) on the performance and exhaust emissions of a single-cylinder diesel engine. An experimental study was conducted using a single-cylinder Yanmar TF85MH-di diesel engine (493 cc) diesel engine operated at 1800, 1900, 2000, and 2100 RPM with 25%, 50%, 75%, and 100% loads. Engine performance was evaluated through power, torque, Specific Fuel Oil Consumption (SFOC), thermal efficiency, and Brake Mean Effective Pressure (BMEP), while exhaust emissions of carbon monoxide (CO), hydrocarbons (HC), nitrogen oxides (NO<sub>x<\/sub>), carbon dioxide (CO<sub>2<\/sub>), and oxygen (O<sub>2<\/sub>) were measured using calibrated instruments. The results showed that increasing engine load reduced SFOC for all fuel blends, with B50 achieving the lowest SFOC (approximately 360 g\/kWh) and the highest thermal efficiency (22-23%) at medium-to-high loads. Torque and BMEP showed only minor differences among the tested fuel blends, whereas B50 produced the lowest HC emission (17 ppm) but higher NO<sub>x<\/sub> emissions at maximum load. Overall, B30 provided the most stable engine performance, whereas B50 achieved higher fuel efficiency and lower HC emissions despite producing higher NOx emissions at maximum load. These findings indicate that both blends are promising renewable alternatives for diesel engine applications.<\/p>\n\n\n\n<p><em>Keywords:&nbsp;Biodiesel Jelantah Methyl Ester, Engine performance, Exhaust emissions, Diesel engine.<\/em><\/p>\n\n\n\n<div style=\"height:2rem\" aria-hidden=\"true\" class=\"wp-block-spacer\"><\/div>\n\n\n\n<div class=\"wp-block-tkuwpbs5-bs5-div ref_ol\" data-aos=\"normal\">\n<div class=\"container\">\n<div id=\"model-response-message-contentr_53180f64958e6cc2\" class=\"markdown markdown-main-panel md-content enable-luminous-fast-follows enable-updated-hr-color stronger\" dir=\"ltr\" aria-busy=\"false\" aria-live=\"polite\">\n<ol>\n<li data-path-to-node=\"0\">[1] Haryono, M.
