摘要：The development of biomass has been an important issue for the past several decades and would remain to be attractive in the future due to its clean, renewable, and carbon–neutral properties. The use of Empty Fruit Bunch (EFB) has been the condition of fibre and conditions of EFB is still fresh. The fiber used has been cut to size between ± 0.5 mm to 5 mm. The purpose of this research is to determine the effect of difference press angle to the quality of briquette. Effect of the angle of the mold on the duration of combustion shows the difference in the time value that is not significant between the angles 65°, 55° and 45°. The rotation of the screw shaft slows down at an angle of 45° with a round of 84.5 rpm, while the rotation of the shaft has increased in rotation at 65° angle with rotation of 90.6 rpm. Differences in the cone angle affect the value of the burning time of the specimen and the rotation of the screw shaft so that it affects the engine performance.
