EKSPERIMENTAL GASIFIKASI TEMPURUNG KELAPA PADA UPDRAFT GASIFIER DENGAN KOMBINASI DUA SALURAN GAS KELUAR UNTUK EVALUASI STABILITAS NYALA API

---

The increasing dependence on fossil fuels poses challenges to energy security, highlighting the need for renewable energy alternatives such as biomass. Coconut shell, a carbon-rich biomass waste, has significant potential to be converted into combustible gas through gasification. Although updraft gasifiers offer high efficiency, they are prone to excessive tar production, which can be mitigated through reactor modification. This study evaluates flame stability during coconut shell gasification using a modified updraft gasifier with combined gas outlets from the upper zone and combustion zone. An experimental method was applied to characterize the performance of the gasification system. The observed parameters included operating time, flame duration, mass flow rates of fuel and air, and air–fuel ratio (AFR). Results indicate that producer gas appeared earlier and burned longer at the upper outlet. The average operation time reached 8753.67 seconds, with the duration of the flame on the top burner and combustion burner respectively being 6719 seconds and 3852 seconds. The average AFR value is 6.69. Keywords: Gasification, Updraft Gasifier, Coconut Shell, Flame Stability, Reactor Modification
