Abstract

Palm sugar flour machine is a machine used to make flour from palm sugar. Palm sugar flour can be used as a processed food product. Compared to manually grinding palm sugar by hand which requires a lot of energy and time, the palm sugar flour machine can be a solution to facilitate the work in the palm sugar processing industry, both on a small and medium scale and a home industry. With this, the author analyzes the electric power of the induction motor on this palm sugar flour machine to determine the power generated from each experiment carried out and the capacity generated from the palm sugar flour machine. The palm sugar flour machine has dimensions of 600 mm x 300 mm x 800 mm with a 1 HP, 1 phase electric motor power, 220 V voltage and 50 Hz frequency. After conducting the analysis of the calculation of electrical power average of the single-phase induction motor on this palm sugar flour machine is 455.81 W and the thickness of floured palm sugar is 0.1 mm.

Abstract

In this article is conducted research to harness wind energy which is generated by a truck that is running on the public road and highway. To take advantage of wind energy of the moving truck is designed a axial movable wind turbine in accordance with the size of the current truck. The purpose of this research is to construct and testing the performance of the designed axial movable wind turbine which is based on the optimum blades size. Number of the blades are six pieces and diameter of the blades are 0.35 m. To test the wind turbine that have been assembled, it is used loads on the wind turbine, respectively, 8 watts and 25 watts. The wind turbine that will be tested is installed on a mini truck. Furthermore, the mini truck runs at speeds up to 80 km/h. This research has succeeded to design and testing a prototype of axial movable wind turbine and the designed wind turbine can resulted electrical energy about 3.5 watts with the load 25 watt bulb. The designed axial movable wind turbine can be installed in the truck by further improving some components of the resulted prototype of the axial movable wind turbine.

Abstract

At Palm oil mill PTPN IV Air Batu, steam boiler and steam turbine is a combination of steam power plant equipment to produce steam and electrical energy. This steam boiler is a type of water tube boiler TAKUMA N-600SA brand with specifications working pressure 22 Bar, Temperature 340OC. The steam produced by the boiler is used to drive a Dresser Rand Type 550W steam turbine for generating 800 kW of electrical power and for steam needs for the boiling process, sterilization of palm oil. In this study the author conducted an analysis of the performance of the boiler and steam turbine, also analyzed the fuel used as a source of heat energy for boiler operations, each are palm shells and fibers. Analysis of the fuel needs of a mixture of shells and fibers at Palm oil mill PTPN IV Air Batu, then for the composition of the three biomass components are shells and fibers with varying ratios: 75%: 25%; 50%: 50%, and 25%: 75%, then the calorific value of each is LHV = 14374.5 kJ / kg, LHV = 12411 kJ / kg, and LHV = 10447.5 kJ / kg. The results of the calculation of the respective fuel needs: 1.617 Ton / Hour, 1.872 Ton / hour, and 2.225 Ton / Hour. From the steam turbine specification data with an output power of 800 kW, the turbine inlet steam pressure is 20 Bar, temperature 340 OC, and steam capacity of 6 Ton/Hour and turbine outlet steam pressure of 3.5 Bar, then through performance analysis, the isentropic efficiency is obtained at 92.32%, and the overall efficiency of the steam power plant is 12.40%.
