Rice husk gasification developed as process that converts organic rice husk into a producer gas. The achievement is to reduce dependency on fossil fuel, reduce pollution and move into green technology. Downdraft gasifier is a reactor that can produce lower tar concentration in the producer gas. There are important objectives had been investigated which are to modify on laboratory scaled downdraft gasifier from the previous project, where suitable with the rice husk gasification system, to measure the exit temperatures in gasifier which it determine tar quantity at the output, to measure the amount of moisture removed from the rice husk where it determine the quantity of moisture in rice husk and, to measure the complete burning of rice husk in a gasifier by taking the time performing the experiments. All the objectives are to be obtaining the output which can be used as a biofuel sources. The method to achieve the objectives, firstly redesign performed using SolidWork software. Next, the temperature determined using thermocouple. Then, next objective which the rice husk drying analysis determined by drying rice husk and scale it with weighing scale. And lastly, burning was determined by using stopwatch and weighing scale with complete fabricated gasifier. The results shows the fabrication of the modification, average exits temperature of producer gas which around 203.93°C, different moisture weight of rice husk which around 10grams and, average time of completes burning of gasifier is 61 minutes and ability to capture producer gas’s flammability. This work concluded by achieves the objectives based on the results and may increase in understanding of the works related.
