However, scientific studies on this particular topic are still limited. Therefore, the purpose of this research is to examine the effect of the aftermarket Juken 5 ECU on the power, torque, emissions, and fuel consumption of the Yamaha R15-V3 bike. The results of the dynamometer testing showed that the motorcycle with the Juken 5 ECU experienced an average increase of 8.09 ± 1.30% in power and 7.79 ± 1.31% in torque, respectively, at 5500 – 11000 rpm. However, the concentrations of Carbon Monoxide and Hydrocarbon emissions also increased by 170% and 360%, respectively. Particulate emission measurements also revealed that the Juken 5 ECU usage resulted in a significant increase in particulate counts. Compared to the standard ECU, motorcycles equipped with the Juken 5 ECU produced 89% and 145% more particulates in the size range of 0.3 – 0.374 μm and 0.374 – 2.685 μm, respectively. The performance and emission data analysis results indicated that the increase in power and torque achieved by the Juken 5 ECU is simply due to more fuel being injected into the combustion chamber. This finding was supported by the results of fuel consumption testing, where using the aftermarket ECU increased motorcycle fuel consumption by 63.6%.","PeriodicalId":167086,"journal":{"name":"Jurnal Rekayasa Mesin","volume":"29 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-08-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"134361106","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The impact of a large number of motorcycle certainly attracts the interest of the industry to produce two-wheeled automotive vehicles. The piston is part of the engine that functions as a compression barrier in the combustion chamber, the piston material is aluminum alloy. Therefore, research was carried out on making pistons with investment casting methods, physical and mechanical patterns from 3D printers on pistons. This research starts from drawing the piston using CAD (computer-aided design), making a printed pattern from a 3D Printer machine with PLA (polylactide acid) material. The mold pattern is coated with a mixture of gypsum cement and silica powder. The casting process with a pouring temperature of 750ᵒC and a mold temperature of 200 ᵒC, 250 ᵒC, 300 ᵒC, 350 ᵒC, and 400 ᵒC. The results showed the largest grain size at a mold temperature of 400ᵒC. The highest hardness at 200 ᵒC mold temperature is 47.00 HRB and the lowest hardness at 400 ᵒC mold temperature is 40.56 HRB. The higher the temperature of the mold used, the level of porosity of a material will decrease. This is due to the temperature difference when pouring the molten metal and the lower mold temperature. This makes the metal solidification time longer. The higher the mold temperature, the slower the solidification time, the larger the grain structure, and the decreased hardness.","PeriodicalId":167086,"journal":{"name":"Jurnal Rekayasa Mesin","volume":"23 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-05-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126670744","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

One of the main things in the design of the press tool is the calculation for determining the type, size and, material of the spring. The spring in the press tool design is placed on the stripper as a pressure plate material before it is formed. The problem that often occurs in the design of the press tool is the initial force of the spring and the number of springs often have high values. This has an impact on the difficulty of the operator in installing the spring during assembly. The installation on the press machine requires more energy that exceeds the operator's power. This problem is often a challenge in itself both in terms of designing and manufacturing press tools. Assumptions and limitations of the problem of the design is 12,64 kN. This force is used for the educational practicum materials. Based on the design calculations the number of springs needed are 4 springs. While the hydraulic required is 10 tons. The results obtained based on simulation analysis using Solidworks software, show that with the number of springs and hydraulics calculated and based on the design form of the stripper installation tool, it is in the safe category.","PeriodicalId":167086,"journal":{"name":"Jurnal Rekayasa Mesin","volume":"175 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-05-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116471439","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Each variation of the flow gap width will be tested at a flow rate of 12 liters/second. Parameters such as mill power, turbine torque, and efficiency will be determined based on the measurement results of the rotational speed of the waterwheel wheel, water level, and braking load. The results showed that the width of the sluice gate flow gap affects the performance of the waterwheel. The highest performance was obtained at a flow gap of 25mm followed by a flow gap width of 35mm, and the lowest performance was obtained at a variation of the slit width of 40mm.
