Abstract

Cadangan batubara sebagai sumber energi tidak terbarukan semakin menipis. Untuk mengurangi laju pemakaian bahan bakar batubara maka dilakukan penelitian blending batubara dengan sumber energi terbarukan berupa biomassa seperti tongkol jagung. Dalam penelitian ini diamati pengaruh rasio tongkol jagung terhadap batubara untuk mendapatkan kualitas campuran bahan bakar terbaik yang memenuhi syarat untuk diaplikasikan pada industri dan pembangkit listrik. Parameter kualitas campuran batubara dan tongkol jagung yang diamati adalah nilai kalor dan kadar sulfur. Bahan bakar batubara yang digunakan dalam penelitian ini memiliki nilai kalor  8403 cal/gram dan kadar sulfur 0.71%. Sedangkan tongkol jagung memiliki nilai kalor 3409.64 cal/gram dan kadar sulfur 0.14%. Dari penelitian ini diperoleh pencampuran terbaik dengan rasio tongkol jagung terhadap batubara sebesar 75% yang memberikan nilai kalor 4741.54 cal/gram dan kadar sulfur 0.26%. Kualitas pencampuran batubara dan tongkol jagung ini memenuhi syarat untuk diaplikasikan pada Pembangkit Listrik Tenaga Uap (PLTU). Pemanfaatan hasil pencampuran bahan bakar ini dapat mengurangi laju pemakaian batubara sebanyak 75%.

Abstract

AbstractThe potential amount of coconut sawdust biomass in Indonesia is very abundant, so far it has not been utilized optimally and tends to be wasted as waste. Coconut sawdust with the main composition of carbon contains heat equivalent to light coal, which is around 4400 kcal/kg. Even though its calorific value is still low, it has the potential to be used as a solid fuel source or an alternative energy source. The calorific value of coconut sawdust can be increased through the pyrolysis process. A study has been carried out on the effect of nitrogen inert gas flowing continuously into the pyrolysis reactor of coconut sawdust biomass waste (Cocos nucifera) on the calorific value of the resulting charcoal. The aim of the research is to determine the effect and optimum flow path of nitrogen inert gas which gives the maximum calorific value of charcoal product. From this study it was concluded that the continuous flow of inert nitrogen gas into the pyrolysis reactor had an effect on increasing the calorific value of the charcoal product by up to 4% compared to not using the inert gas. The optimum nitrogen gas flow rate is 2 L/minute giving a maximum effective calorific value of 7200 kcal/kg

Abstract

Rice Husk Ash (RHA) is a material that has the potential to be used in Indonesia because of its high production with sampling results during the rice milling process which produces quite a lot of waste, which is equal to 20% of the grain weight with the characteristics of rice husk which is coarse, has low nutritional value, has a high density. low and high ash content. The high content of silica in rice husk can be a reference for its use as a raw material for making silica. Through this research the authors did this to determine variations in the concentration of acid types on the quality of the water content (%) of the resulting silica gel and to determine the characteristics of acid type silica gel. After conducting research using quantitative methods through data collection and data processing, it was found that the concentration of various types of hydrochloric acid (HCl) had a higher level of water content than the type of citric acid (C6H8O7), obtained the concentration of 9 M, while the FTIR test results showed that silica in the type of acid used contained OH groups which identified silanol (SI-OH) absorption range 3450 - 3550 cm-1 and siloxane functional groups (Si-O) absorption ranges of Si-O functional groups, namely 1075 - 1095 cm-1.
