Abstrak: Desain kompor berbahan bakar biomasa untuk keperluan memasak, dimaksudkan untuk mendapatkan performayang optimal. Performa dilihat dari efisiensi pembakaran, efisiensi termal, dan emisi gas buang. Ketinggian ruang bakarkompor biomasa didesain sama dengan diameternya (H = D) atau 1-2 kali diameter (H = 1-2 D). Pada penelitian ini digunakandua buah kompor dengan perbedaan ketinggian ruang bakar (H1 = 20 cm dan H2 = 27 cm), dan diameter (D = 20 cm) danmenggunakan bahan bakar biomas yang sama. Performa dari kedua kompor diukur dari efisiensi termal, laju konsumsi bahanbakar, efisiensi pembakaran dan emisi gas buang. Pemantauan emisi gas buang dianalisa dengan menggunakan gas analyzerportabel. Hasil efisiensi pembakaran kedua kompor berbeda yaitu 99,5% (kompor 1) dan 98,2% (kompor 2). Efisiensi termaldari kompor 1 dan 2 adalah 25,4 dan 11,1%. Laju konsumsi kompor 1 relatif stabil dibandingkan dengan kompor 2 selamapembakaran. Emisi CO yang dihasilkan dari kompor 1 dan 2 adalah 328 dan 555 ppm. Hasil gas buang SOx dari kompor 1 dan2 adalah 31 dan 38 ppm. Sedangkan emisi gas buang NOx dari tungku 1 dan 2 relatif berbeda dengan nilai 19 dan 13 ppm.Kata kunci: kompor biomasa, efisiensi pembakaran, efisiensi termal, emisi gas buangAbstract: Design of the stove based on biomass fuel for cooking system have been performed. The performances are evaluatedby burning efficiency, thermal efficiency, and flow gas emission. Design of high (H) and diameter (D) of biomass furnace is 1until 2 times of the diameter. In this research, the 2 stoves with difference of high of furnace (H1 = 20 cm and H2 = 27 cm) andsame of diameter (D = 20 cm) and biomass fuel was used. The performance of stoves are measured from thermal, fuelconsumption rate, burning efficiency and flow gas emission. Portable gas analyzer is used to monitor of emission gas (CO,SOx, NOx). The results of burning efficiency of both stoves are different, that is 99.5% (stove 1) and 98.2% (stove 2). Thermalefficiency of stove 1 and 2 are 25.4 and 11.1%, respectively. The consumption rate of stove 1 is relatively stable depend onstove 2 as long as burning time. The CO emission of stove 1 and 2 are 328 and 555 ppm. The results of stove 1 and 2 for SOxemission are 31 and 38 ppm. The NOx emission of stove 1 and 2 are different with value of 19 and 13 ppm.Keyword: biomass stove, burning efficiency, thermal efficiency, flow gas emission
