Oil production in Riau until the year 2011 has reached 35 million tons and production is produced from palm shell of 2.8 million tonnes . Especially in the application of gasification stove for cooking can improve the efficiency of the use of palm shells . This study uses three units of gasification stove with stove dimension 1 ( H1 = 16 cm , D1 = 10cm ) , stove 2 ( H2 = 16 cm , D2 = 12 cm ) , and the stove 3 ( H3 = 20 cm , D3 = 12 cm ) . The fuel used is oil shell with moisture content of 8% , 9 % and 8 % . Method of boiling water test ( WBT ) is used to evaluate the performance of the stove . Additional parameters such as the operating time and temperature flame of the stove as well as evaluate the performance of the stove . The results were obtained an average start-up time of 4.48 minutes and the operation time of the forced draft gasification stoves reached 13.83 minutes . The thermal efficiency of the gasification burner forced draft is approximately 41.49 % to 60.34 % , with the highest efficiency is a stove with a diameter of 12 cm and height 16 cm . Although the resulting fire is still reddish yellow , but the forced draft gasification stoves capable of producing up to 4.42 kWth heat energy with the highest flame temperature reaches 900oC . These results indicate that the operating conditions of forced draft gasification stoves greatly affect the performance of the stove
