Abstract

This research present the torque and exhaust emission level from four stroke indirect injection fuel system engine. An engine fueled by ethanol gasoline blend. The original Engine Controle Module injected lean mixture into Combustion Chamber. Lean Mixture decreased Torque drastically. Therefore, the Engine Controle Module was modified to produce stoichiometric mixture. Injector was controlled by digital pulse of Fuel Controller. Ethanol was added into gasoline 0% - 100% at 1500 rpm-5000 rpm. The result demonstrate that increasing ethanol concentration into gasoline fuel system, decreasing Torque, and CO, HC, CO2 emission. By increasing ethanol concentration also increase CO2 emission to 34.6%.

Abstract

Hydrogen reformer is a principle of hydrogen formation by using the reaction between reactants with a catalyst and a heating process in vapor form. Copper powder was used as the catalyst with a porosity of 28.245% and 31.736%, and a heat temperature of 310 oC. Variation of the ratio between water and virgin coconut oil (VCO) mixture of 1:1, 1:2, 1:3, 1:4 and 1:5 was developed to investigate the hydrogen generated productivity. The images of burning flame was taken at the outlet pipe of steam reaction to indicate the productivity of the hydrogen. The results shown that the productivity of the hydrogen was obtained by calculating the images of flame colors. The images indicate that the productivity of the hydrogen increase with adding virgin coconut oil (VCO) to water is greater. The average amount of energy and the power needed to react all variations on a comparison of hydrogen reformer tube 5 are 53.53885 kJ and 0.18666 kJ/sec, respectively.

Abstract

There were two kinds of monsoon winds in Indonesia. They are the east and the west monsoon winds. Both of them blow alternately in a year through the Indonesian territory. The velocity and energy of monsoon winds in Indonesian territorial sea were mapped by using MatLab program. The velocity and energy data were obtained by using QuikSCAT satellite from January 1999 until December 2009, meanwhile WindSat from January 2004 until December 2014. The results show that high energy of monsoon winds start from Indian oceans until Nusa Tenggara sea, then from Arafuru sea to Banda sea, Java sea, Karimata strait and the southern region of south Sulawesi.

Abstract

This study was conducted to determine the characteristics of premixed combustion of a mixture of castor oil - LPG on a circular tube burner. Percentage of LPG fuel in a mixture of jatropha curcas oil - LPG varied as much as 10%, 20%, 30%, and 40% of the mass flow jatropha curcas oil vapor. Considering the flame of fire there are two angles formed which describe burning velocity. Also there are formed two cones of fire where the bright blue inside cone is a premixed flame, while the outer blue white cone is flame a diffusion flame. An increase in the percentage of LPG makes the value of top and bottom angle increase. So that the burning velocity on the upper angle decrease whilst on bottom angle increase.

Abstract

The absorpstion of CO2 is aimed to increase the methane gas fraction in biogas. Enhancing methane fraction hopefully will increase the total energy of the biogas it self. The purification process of biogas minimizing another elements maintains combustion, especially minimizing H2O, CO2, and H2S. The purification using KOH as the absorbent to decrease the CO2. The result shown that the content of CO2 decreased into 27% from 35.5%, the average content of CH4 increased from 18% to 48.5%. Increasing KOH composition decreases bubble generator diameter and mass flow.

Abstract

PT. APW is a manufacturing company of the bus body. One of the production process department in PT. APW is frame work department. It is in charge of making the bus body frame. The problem faced in this department is inadequationvof the current system. It is because the work is done manually and is not by using computer applications with database systems. The study used the assembly information management system based on Group Technology to help its assignment of bus body frame assembling process and the work report. Management Information System Design Assembly (SIMPER) were performed by using the Microsoft Access 2013 to produce a prototype application SIMPER consisting of phase identification, analyzing, planning, designing, implementating and testing. By designing this SIMPER prototype application, it is expected to meet the needs of users of information systems in Production Manager, SPV and Admin employees.
