Abstract

Biomass potency in Indonesia is very abundant both from the animal manure or plant. Agriculture and plantations waste which are abundant can be utilized as the energy source. One of them is the rice husk. This experiment used rice husk gasification method with downdraft gasifier to turn it into a combustible gas that will be burned in the combustion chamber cyclone. The advantage of gasification compared to the method of the direct combustion is cleaner burning and particulates and contaminants can be removed before burning. The cyclone fuels can produce good mixing which is suitable for gas with low calorific value. The composition of syngas produced by gasification of rice husk are H2 13,6%, CO 14,9%, CO2 12,9% dan CH4 2,3% [1]. After leaving the reactor syngas entry cyclone separator to remove moisture and contaminants, and then go to the storage tank and eventually went to cyclone fuel to be burned after mixing with air through a different inlet. After that the different value of AFR will vary to see the changes in temperature of the flame, the fire position in the combustion chamber and the flame shape. From the experimental results in AFR = 1.59 fire in the combustion chamber air beetween 1 and 2, in the AFR = 1.14 The fire in the combustion chamber in the plane 2, in AFR = 0.69 fire in the combustion chamber 3 and in the air beetween AFR = 0.27 fire outside the combustion chamber after mixing withfresh air.

Abstract

Press Machine For Switch Assy EPB module is an SPM (Special Purpose Machine) with a special function to carry out the pressing process of EPB (Electric Park Brake) products, namely an electronically controlled parking brake, where the driver activates the restraining mechanism with a button. So far, the epb product assembly process uses a manual mechanism by pressing the parts of the operator. This process is still not optimal, therefore it requires the development of a new EPB assembly system to improve and achieve maximum production processes. In this paper, an EPB product pressing system has been made using a jig. The jig is designed and manufactured using a photoelectric sensor integrated with the PLC. This study aims to improve the Quality Assurance of each EPB product and increase productivity to be more stable. The previous EPB product assembly process was carried out manually by the operator and there were often errors in the form of installation discrepancies in the process. In this paper, a press has been designed and made with sequential system operation with a ladder language program stored in a PLC. Sequential will run based on limit switches and photoelectric triggers to detect every product that enters the pressing process. The results of this study the quality and efficiency of the EPB assembly process increased where the human error that caused product failure was reduced, besides that the tools made had advantages among idle time in the EPB production process could be minimized.
