Pengaruh Aliran Nitrogen Kontinyu ke Dalam Reaktor Pirolisis Limbah Biomassa Serbuk Gergaji Batang Kelapa (Cocos Nucifera) Terhadap Nilai Kalor.

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 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.

Extraction of Vegetable Oil from Candlenut Seeds (Aleurites Moluccana L. Willd.) Using the Microwave Hydrodiffusion and Gravity (MHG) Method

The microwave hydriffusion gravity (MHG) method is a relatively new extraction method in order to improve the quality of oil obtained from plant materials or spices. The extraction process is carried out without involving solvents so it is safe for consumption. However, the MHG method has never been applied to the extraction of candlenut (Aleurites moluccana L) seeds. The operating conditions and variables in the research on the extraction process of Aleurites moluccana L are microwave power (300; 450; 600 W), extraction time (15-75 minutes) with 15-minute intervals, material size (1;2;3 cm), mass of raw material 100 gr, and atmospheric pressure. Material treatment consisted of 3 types of material conditions including seed material which had been roasted for 10 minutes over low heat, seed material which had been in the oven for 45 minutes, and seed material which had been without pretreatment. The results of the oil extract were analyzed using GC-MS to identify the components of the constituent compounds. Then, evaluating the mathematical modeling of the extraction process is based on first and second order kinetics. Roasted material showed the highest yield with material size parameter in 1 cm, microwave power of 600 W, and extraction time at 30 minutes, produced 5.55% (%w/w). Furthermore, the pyrazine component (36.814%) is the largest compound from the extraction of Aleurites moluccana. The first-order kinetic model has a regression that is close to the experiment with (R2 = 0.9453). Modeling quality is also supported by a very small total sum of squares (SST) value of 6,44E10-4. Therefore, the MHG method is quite effective in producing Aleurites moluccana oil with better quantity and qualit
