Abstract
Cerbera Manghas is a plant that is often used as urban greening so that this plant has the potential to be developed into a source of alternative fuel in Indonesia. The material of solid fuel briquette is waste leaves of Cerbera Manghas tree and tapioca flour are used as binder material. The composition of this briquette is 10% mass of tapioca flour and 90% mass of Cerbera Manghaswaste leaves. The highest heating value (HHV) of this briquette is 4167 Kcal/kg. The particle size of this briquette affects the physical and burning characteristics. This optimizesresearch particle size and pressure of the press machine during the briquette forming process. The two parameters were evaluated for the combustion characteristics include Flame temperature, Ignition timing, Burning time, and Combustion rate. The higher value of flame temperature,ignition time and burning time are caused by the greater the hydraulic pressure. Besides better the briquettes’quality are obtained the smaller of combustion rate, so that the briquettes are more durable and required the ignition time length. The best briquettes of Cerbera Manghas leaves are those with particle size of 60 mesh and forming pressure of 2 MPa, which have a flame temperature of 522°C, an ignition time 268 second, a burning time of 7293 second, and a combustion rate of 0.0026 gr/s.
