Abstract

The increasing human population, the use of fossil energy such as oil also increases. While fossil energy is one of the largest contributors to carbon emissions that can cause climate change that can be done to control climate change is to switch to the use of renewable energy. The investigation takes the shape of a vertical axis Savonius turbine blade design. The blades are made of a composite material called carbon fiber, and the number of blades varies between 4, 6, and 8 pieces. The study's findings were tested utilizing a blower-generated wind source with wind speeds of 4m/s, 4.5m/s, and 5m/s. A wind tunnel consisting of acrylic material and pipes as a frame construction was used in the test. The test findings show that turbine blades with a total of four blades produce the maximum generator power of 0.274 watts at a wind speed of 5 m/s. Meanwhile, the turbine blade with 8 blades has the lowest output power at a wind speed of 4 m/s and a power value of 0.0028 W. Then, with 8 blades, it has a relatively low output energy compared to 4 and 6 blades. Therefore, the highest efficiency performance of wind turbine use is achieved by a turbine with a number of 4 blades with a maximum efficiency is 9,16% and the minimum efficiency it seen in a wind turbine with a number of blades 8 within 0,07%.

Abstract

Research on aluminum metal matrix composites reinforced with ceramics using powder metallurgy methods has recently been increasingly in demand to be developed. The goals of this study determined the effect of differences in compaction pressure on the density and hardness properties of the resulting composite. The research method used of is following the stages of the powder metallurgy process, which includes material preparation, mixing and compaction. The mixing of the composite constituent powders was carried out using the mechanical alloying method using a horizontal ball mill for 4 hours. While the hot compaction method used is two-way compression compaction, using a hydraulic pump. The matrix material used is recycled aluminum powder, and the reinforcing material is powder from tin mine tailing silica sand. The hot compaction process was carried out at 500 0C and held for 15 minutes. Two-way compacting pressure variations used 4400 Psi, 4500 Psi and 4600 Psi. Density testing refers to Archimedes with the ASTM B962-15 standard. Meanwhile, the hardness test used the Rockwell hardness testing machine, referring to the ASTM E18-15 standard. The results of the density test and hardness test showed a tendency for the value to increase with increasing compaction pressure applied. The highest density was 2.147 g/cm3 for a sample with a compaction of 4,600 Psi, with the highest hardness value being 53,11 HRB. Based on micro-photographs, it shows that the interlocking mechanical bonds at lower compaction pressures tend to be weak, fractures at the grain boundaries are clearly visible and the pattern of damage tends to show brittle/brittle fractures.

Abstract

This study aims to determine the accuracy of the Anet A8 3D Printer in printing curved products with the infill speed, print speed and layer height factors in order to obtain optimal results and determine the most influential parameters in printing curved products using the Anet A8 3D Printer. The method used in testing the accuracy of printing 3D printing products is Taguchi L9. From this study it can be concluded that the most optimal process parameters for the accuracy of the dimensions of the specimen diameter are successively for accuracy, namely layer height (0.3000 mm), infil speed (50 mm/s) and layer speed (30 mm/s) then the most optimal process parameters for the accuracy of the curved dimensions of the specimen are successively for accuracy, namely layer height (0.2000 mm), infil speed (50 mm/s). s) and layer speed (40 mm/s). The results of the ANOVA analysis show that the most contributed parameter in printing curved specimens with the diameter dimension is the layer height and the curved dimension is the infill speed.

Abstract

Metal cutting is the stage of processing profile raw materials and steel plates according to the cut marks that have been set in the marking process. One of the metal cutting techniques is to use oxy acetylene welding where the cutting occurs due to the reaction of oxygen and steel. Oxy acetylene welding is a manual cutting and welding process, in which the surfaces to be joined are heated until melted by the flame of acetylene gas, namely burning C₂H₂ with O₂ with filler metal or without filler metal where the joining process is without pressure. Besides for welding purposes (connection), oxy acetylene welding can also be used as preheating, brazing, cutting and hard facing. In the process of cutting iron pipes using oxy acetylene welding manually, the problem that is often found is the results of uneven and not straight cuts. This causes a leveling process to be needed on the edges that are cut so that they are flat and straight. In this research, a pipe cutting machine with oxy acetylene welding has been made which aims to produce straight, smooth, and even pipe cutting. The pipe cutting machine that has been made can produce flat, smooth, and straight iron pipe cuts on iron pipes with a diameter of 4.5 inches, 3.5 inches and 3 inches with a cutting time of 32 seconds, a motor wave rotation speed of 5.8 Hz, and a cut tolerance of ± 3 mm.

Abstract

The main contributor to the problem of slum settlements in urban areas is the issue of waste. Waste management that does not comply with the technical requirements encourages local governments to build TPS3R in residential areas. TPS3R KSM Kawa Begawe in Selindung Village is one of the real works of collaboration between the local government and the central government. TPS3R was founded in 2016 and developed in 2022 by providing organic and inorganic chopping machines, hydraulic press machines and maggot feed pulping machines. The purpose of this research is to find out whether this machine has been used optimally and has been able to improve the community's economy. The method used is a mixed method, where quantitative data is analyzed using simple calculations and qualitative data is analyzed using descriptive analysis. The results of the analysis found that as the population increases, TPS3R is urgently needed as an effort to reduce waste production by reducing disposable items or processing waste into other useful products and can open up new job vacancies so that it eventually becomes a source of income for the local community. In terms of the economic development plan, when this machine has been used optimally, this place will become a qualified source of income for the local community. The results of this study are certainly proof that TPS3R does not only answer the problem of environmental pollution caused by waste, but can also produce products that have economic value from waste processed at TPS3R KSM Kawa Begawe.

Abstract

Drying is a process of transferring heat and water vapor simultaneously which requires heat energy to evaporate the water content. This heat energy can usually be obtained from sunlight. However, during the rainy season, this condition inhibits the drying process that utilizes sunlight, so the drying process takes a long time. Therefore we need a tool that can dry clothes without depending on the heat source from the sun's rays. The clothes dryer is a tool used to dry clothes with artificial heat energy, one of the artificial heat producers is a heating element or what is often called a heater. The artificial heating element used in this research is Electric Heater. This Electric Heater is equipped with a fan that can produce an indoor temperature of up to ± 52.3º C so that the heat generated by the Electric Heater can convert the water contained in the clothes into water vapor which will then be released into the environment with the help of a fan. Based on the results of calculations and testing, the ability of this tool is able to evaporate an average mass of water of 535.8 grams/hour and this machine reaches its optimum point for the number of drying clothes that can be dried as many as 6 clothes.
