Abstract

Briquette is one of the alternative energy sources as a satisfactory substitute for fossil fuels in which the availability decreases every single day. The main materials of briquettes can be biomass. Biomass is an organic material produced by photosynthetic process, the materials may be product, remnant or waste. One of the potentially great biomass to be used as the main ingredient of briquettes is corncob. This study aims to (1) know the characteristics of corncob briquettes with adhesive jackfruit seed flour including moisture content, ash content, volatile matter and calorific value, (2) know the characteristics of the best corncob briquettes based on SNI standard. Corn cobs were converted first to charcoal with carbonization process, and then the charcoal was mixed with adhesive derived from jackfruit seed flour. In this study, variations of corncob to jackfruit seeds ratios were 90%: 10%, 85%: 15% and 80%: 20%, respectively. Then a mixture of charcoal and flour was molded with a molding pressure variation of 100 kg/cm2 and 120 kg/cm2. The parameters of briquette characteristics based on SNI 01-6235-2000 are moisture content, ash content, volatile matter and calorific value. The results show that the best characteristic briquettes is briquettes with sample code of B1 with charcoal to jackfruit flour ratio of 90% to 10% and printing pressure of 120 kg/cm2. The briquettes have water content characteristics of 7,0073%, ash content of 6,8876%, volatile matter of 17,8983% and calorific value of 6241,8137 cal/gram. But overall, the briquettes have not met the SNI 01-6235-2000 standards because the level of volatile matter in the briquettes exceed the maximum limit that has been determined i.e. 15%.

玉米穗外露的特征:用菠萝蜜作为替代燃料
型煤是一种令人满意的替代化石燃料的能源,其可用性日益减少。型煤的主要材料可以是生物质。生物质是通过光合作用产生的有机物质,这些物质可以是产物、残余物或废物。玉米棒子是一种潜在的巨大生物质,可作为蜂窝煤的主要成分。本研究的目的是(1)了解粘附菠萝蜜籽粉的玉米芯型煤的特性,包括含水率、灰分、挥发物和热值;(2)了解基于SNI标准的最佳玉米芯型煤的特性。采用炭化工艺将玉米芯转化为木炭,然后将木炭与菠萝蜜籽粉制成的粘合剂混合。在本研究中,玉米芯与菠萝蜜种子比例的变异分别为90%:10%、85%:15%和80%:20%。然后用100 kg/cm2和120 kg/cm2的模压变化对木炭和面粉的混合物进行模压。基于SNI 01-6235-2000的型煤特性参数为含水率、灰分、挥发物和热值。结果表明,炭与菠萝蜜粉比为90% ~ 10%、印刷压力为120 kg/cm2、样品代码为B1的型煤性能最佳。该型煤含水量为70073%,灰分含量为6,8876%,挥发物含量为17,8983%,发热量为6241,8137 cal/g。但总的来说,这些型煤没有达到SNI 01-6235-2000标准,因为型煤中挥发物的含量超过了已确定的最大限量,即15%。
