Abstract: This research is experimental in nature, involving direct measurements of gas emissions from briquettes, Sentang wood (Azadirachta excelsa), Petai wood (Parkia speciosa), and Rambutan wood (Nephelium lappaceum). Tests were conducted using an exhaust emission measuring device for three main parameters: SO₂, NO₂, and CO. In this study, the mixed briquettes of cow manure, rice husk, and wood dust showed the lowest SO2 emissions (1.2 mg/Nm³) compared to Rambutan wood, which had the highest SO2 emissions (94.4 mg/Nm³), Petai wood (75.4 mg/Nm³), and Sentang wood (7.6 mg/Nm³). This indicates that briquette blends derived from cow manure, rice husk, and wood dust are relatively cleaner in terms of sulfur emissions. While Sentang wood produced the highest NO₂ emissions (12.8 mg/Nm³), the mixed briquettes of cow manure, rice husk, and wood dust came second (7.4 mg/Nm³), whereas Petai wood and Rambutan wood produced lower NO₂ values, 3.6 mg/Nm³ and 4.6 mg/Nm³ respectively. For CO emissions, briquettes of cow dung, rice husk, and wood dust mixture had the highest CO emission level (1,857.6 mg/Nm³). Petai wood and Rambutan wood showed slightly lower CO emissions than the briquettes, at 1,643.8 mg/Nm³ and 1,568.2 mg/Nm³ respectively. Sentang wood had the lowest CO emissions (1,502.4 mg/Nm³), indicating that combustion of this material was more efficient than the others.
