Abstract

Solar energy is the energy that is most easily obtained in the conditions of our country which is in an area that is crossed by the equator. Energy that can be in the form of sunlight and heat from the sun can certainly be used as alternative energy to produce electrical energy. One technology that is able to utilize solar thermal energy is a solar parabolic trough system as a solar thermal collector. From the heat source produced, it is expected to be able to produce electrical energy generated by thermoelectric, where the thermoelectric heat side is obtained from the heat source in the solar parabolic trough. By conducting experiments to manufacture a power plant that utilizes a solar parabolic trough which is integrated with a thermoelectric type TEG-SP1848-27145SA as many as seven pieces, then the experimental data is taken from the device capable of producing electrical energy output. The output of electrical energy in the form of electrical voltage produced is strongly influenced by the difference in temperature on the hot and cold side of the thermoelectric, the greater the temperature difference, the greater the energy output that can be generated. From the experimental results, the highest temperature difference produced is 20.7oC with a current value of 85.93 mA and a voltage of 2.51 volts in the direction facing north, and the highest temperature difference produced is 11.5oC with a current value of 77.63 mA and a voltage of 2.15 volts in the direction facing east to west. The highest thermoelectric efficiency is 14.996% with the direction of the solar parabolic trough facing east to west.

Abstract

Urokep leaf or Chinese Ketepeng (Senna alata) is one of the most commonly found medicinal plants and can be used as raw material for herbal tea bags. An essential process in making herbal tea on a household scale is the chopping of dried leaves into a powder that is ready to be put into teabags and pressing the teabags. The leaf shredder process can use a chopper and a blender, while the teabag pressing process uses an impulse sealer. This study aims to compare the energy needed by choppers and blenders in making urokep leaf teabag powder, as well as the use of impulse sealers with element lengths of 20 cm and 30 cm. The research was divided into two stages, i.e. chopping the dried leaves into the powder stage and pressing the teabags stage. The chopping dry leaf into the powder stage was counted by calculating the time for the chopper and blender to powder 1 kg of dry leaves. The pressing of the teabags was carried out by calculating the pressing time of 1000 teabags using an impulse sealer with 20 cm and 30 cm element length. The amount of electrical energy is used by multiplying the electric power by the time of each tool.The results showed that the electrical energy used by the chopper to shredder 1 kg of dry Urokep leaves was 0.10833 KwH, while the blender required more energy, which was 0.27833 KwH. The electrical energy to press 1000 teabags used by the impulse sealer 20 cm is lower at 0.310 KwH than the impulse sealer 30 cm 0.633 KwH. The combination of a chopper and impulse sealer 20 cm is highly recommended for household-scale industries.

Abstract

The Cylinder sleeve is an engine component that is mounted on the cylinder block which functions as a piston glide base. The cylinder sleeve is made of FC250 gray cast iron. FC250 is a gray cast iron that has lamellar graphite with a tensile strength of at least 250 MPa. This study aims to determine the mechanical properties of hardness and wear of the Cylinder Sleeve made of gray cast iron FC250. The method used in this research is gray cast iron which is cut with a length of 5.5cm, thickness 0.7cm, height 0.7cm which is formed according to the standard size of the hardness and wear test. The tests carried out include testing brinell hardness and wear. The results showed that the lowest hardness value was 134.63BHN and the highest hardness value was 191.43BHN. The increase in hardness values is influenced by the carbon content that cannot be spread evenly, which is followed by a fast cooling rate. The results of the wear test obtained the lowest price of 0.00017mm³/kg.m and the highest wear price of 0.00028 mm³/kg.m.

Abstract

The Ministry of Energy and Mineral Resources (ESDM) said that the current national electricity consumption is still relatively small, namely one-quarter of the indicators of developed countries in the world. With a figure of 956 Kilowatt-hour (KWh) per capita, Indonesia's electricity consumption has only reached 23.9% of the electricity consumption of developed countries of 4000 KWh per capita. Based on field observation data, the temperature in the economizer pipe ranges from 280 0C to 330 0C even though it should be between 350 0C to 470 0C (Manual Book PT. Wijaya Triutama) is based on operational standards for a maximum load of 4 MW. A decrease in the temperature in the economizer pipe which is already below the limit will certainly cause a reduction in the electrical power generated and then fuel consumption will increase from 5 tons of wood waste per hour to 7 tons of wood waste per hour. Based on data analysis and discussion, conclusions can be drawn regarding the economizer analysis on boilers that work below the normal limit of gas temperature of 330.9 0C which should be normal temperature of 470.6 0C then water temperature of 152.3 0C which should be 234.8 0C due to several factors including is the contamination in the economizer pipe which causes the temperature to drop, then the efficiency value in the economizer before the research is 58.0% and after repairs and cleaning of the economizer pipe is 70.2% the value of the temperature increase is very influential on the boiler that produces steam pressure Very large.

Abstract

This research aims to find out the effect of shot peening on the rate of fatigue crack propagation in the aluminum alloy 5083, which has undergone the friction stir welding (FSW) process. In general, the FSW welded joint is subjected to softening and decreasing mechanical properties compared to the parent metal. Shot peening treatment is expected to reduce the rate of fatigue crack propagation. The FSW process is carried out on 3 mm thick aluminum and butt joint welding joints. The machine used in the FSW process is a milling machine with a spindle rotation of 910 rpm and a table speed of 18.2 mm/min. The surface of the material that has been processed by FSW, then proceeds with the shot peening process by firing steel balls for 6 minutes, 10 minutes, and 14 minutes. The results of the FSW process without shot peening (NP) and FSW with shot peening (SP) microstructure, SEM, and fatigue crack propagation tests were performed. The test results show that the FSW process with shot peening has decreased the rate of fatigue crack propagation marked by an increase in the value of the Paris constant (n). The increase in Paris's constant values (n) in the FSW with SP6, SP10, and SP14 was 0.241%, 5.428%, and 13.371%, respectively.

Abstract

The tool pin rotational speed and welding speed affect the electrical conductivity value of the Al-Cu connection. Al-Cu connection is a butt joint resulting from the friction stir welding (FSW) process. The material used is Al 6061 and pure copper. The friction stir welding (FSW) process uses a pin tool with a pin design that integrates with the pin tool and a three-degree angle. The purpose of this study was to determine the electrical conductivity value of the Al-Cu connection with the friction stir welding (FSW) process at the butt joint connection. The variables used in this study were pin tool rotation speeds of 800, 1000, and 1250 RPM and welding speeds of 10, 12.5, and 16 mm/min. Tests conducted in this study were macro structure testing, measurement of resistance values,  and microhardness testing. Besides, an analysis of heat input and welding time is needed for each variable. The results of macro and XRD structure test results show that in the aluminum and copper connection, there are intermetallic compounds in the form of AlCu and Al2Cu. The results of the analysis state that the welding results with a welding speed of 12.5 mm/min are the most optimum variables. The welding process results in conductivity values ranging from 27.173 mΩ-1mm-2 and 28.09 mΩ-1mm-2. The presence of intermetallic compounds affects the conductivity value of the connection.
