Abstract

Palm oil processing insdustries does not only produce palm oil but also produce palm waste. The palm waste is filth of palm processing result which is mostly used for fertilizer only and a few of it is used for fuel. The use of palm solid waste, which is not maximal, let the existing energy potency is wasted uselesly. The objective of this research is to calculate the calor value contained in the palm solid waste to be used asfuel of the boiler in palm industries and other industries. The experiment is conducted by burning the palm solid wasteby using calorimeter bomb in 8 mixing ratios. Each mixing ratio is tested 3 times to get the average calor. From the experiment result, it is obtained that the average calor values are: 100% shell = 23.529,47kj/kg,  100% fiber = 20.588,26 kj/kg, 100% empty bunch =18.382,39 kj/kg, 20% shell, 80% fiber= 21.568,67 kj/kg, 0% shell,  60%fiber, 40% empty bunch = 19.117,69 kj/kg, 10% shell, 60% fiber, 30% empty bunch = 19.607,89 kj/kg, 10% shell, 30% fiber, 60% empty bunch = 18.627 kj/kg, 20% shell, 40% fiber, 40% empty bunch = 20.098,08 kj/kg. Thus, the highest calor value is in the burning of 100% of shell and the lowest is in the burning of 100% of empty bunch.

Abstract

This research designed and analyzed the use of current energy by employing the Darrieus turbine type H. This turbine was tested in an irrigation located in Bukit Meusara, Aceh Besar. It has a dimension of 0,3 m x 0,3 m with a blade shaped of NACA 0015 and tested on a variation of water speed flow of 1,43 m/s, 1,91 m/s and 2,16 m/s. An experiment on the influence of angle of attack was also done on -50, 00, 50 and 100. The results showed that the angle maximum turn was 90 rpm with the water speed flow of 2,16 m/s at angle of attack of 50. The maximum power produced by the turbine was as substantial as 26% of efficiency.
