On a 2-stroke motorcycle, this can be wasteful and one of the causes is the incomplete combustion process. In the fuel reporting system on a 2 stroke motorbike, it still uses a carburetor system and also uses a valve. The valve is used in learning the fuel and air mixture from the carburetor. Valve mechanism to regulate the amount of fuel and air mixture entering the combustion chamber. In addition, it also acts as a door to open and close the combustion chamber when flushing of the cylinder occurs. If the valve system is not optimal, a lot of the fuel and air mixture is wasted and the motorcycle engine does not work optimally. Because when suctioning the tongue, the valve must immediately open quickly and wide so that the fuel and air mixture that enters is maximized. Likewise, when exhausting, it must also close quickly so that the fuel and air mixture does not return to the carburetor. In writing this research, the data sources required consist of two data, namely 1. Secondary Data Secondary data is data obtained from other existing sources, including books, related journals, and websites. 2. Primary Data Primary data is data obtained from the results of testing the use of standard valves that are replaced with racing carbon fiber valves. Primary data obtained during the test includes the results of changes in power (Hp) and torque (Nm) obtained. Based on the data obtained from the results of the research that has been done, it shows that there is a difference in the power obtained on a motorbike using a standard valve with a motor using racing carbon fiber valves. Based on the graphic image above, the results of the study show that the power generated by the racing carbon fiber valve components has a slightly higher value when compared to those using standard valve components. The difference in power generated is due to the difference in the size of the valve produced by the valve used. . This is because the fuel and air mixture enters the cylinder chamber faster so that combustion becomes better by replacing the valve racing carbon faiber components.

CV YZX is a manufacturing company in the stainless steel hardware sector that specializes in hardware and detailing. This company actively produces for the needs of individual consumers and orders from other companies. One of the problems faced by CV YZX is the use of production machines that are less than optimal at every stage of the production process. Production machine performance that is not optimal can increase the total value of production time (makespan), which in turn can cause delays in completing products and delivery to consumers. This research aims to find the minimum total production time value by applying the Campbell Dudek Smith method to production scheduling. The calculation results show that by applying the First Come First Serve (FCFS) production scheduling method, the company obtained a makespan of 39.64 hours. However, by using the proposed method, namely Campbell Dudek Smith (CDS) in production scheduling, the results of the makespan calculation show a figure of 33.58 hours. A comparison of the two methods shows that the proposed scheduling using the Campbell Dudek Smith method has a lower makespan value compared to the company method (FCFS), resulting in time savings of 6.06 hours or the equivalent of 15,3%.

Published: September 2024

One of the important parts that ensures the availability of electrical energy supplies which takes place from the central power plant and then through the transmission line to distribution to the load is the insulator. However, over time, insulators can experience anomalies such as corrosion. Insulator corrosion can be caused by many environmental factors, including pollution, humidity, high temperatures and exposure to chemicals. Previously, maintenance personnel usually identified the level of corrosion on insulators visually by using their knowledge and experience through routine inspection activities to check the condition of the insulators. This technique, however, takes a long time and is often subjective. Therefore, in this research, the way to detect the degree of corrosion on insulators is by using image processing and using active contour segmentation to determine the degree of corrosion on insulators and using decision trees as a method to create a classification model for the degree of corrosion. This can help reduce reliance on subjective human judgment, increase the effectiveness of the recognition process, and optimize overall isolator maintenance efforts. The application created in this research has a user interface that makes it easier to process images of corrosion insulators. The front page, practice page, and test page comprise this interface. Meanwhile, the results of classification using a decision tree for the low category are in the ratio x1 < 0.082104, the medium category is in the ratio 0.082104 =< x1 < 0.15061, and the high category is in the ratio x1 >= 0.15061 with an accuracy result obtained of 93.33% for test image data and recall and precision values ​​obtained 100% results.

Renewable energy is increasingly popular and in demand throughout the world as an alternative to increasingly limited fossil energy, one of which is wind turbines. Wind turbine research on ships has great potential in developing renewable energy at sea. The aim of this research is to increase the efficiency of converting wind energy into electrical energy by designing a low cost wind turbine and analyzing the design efficiency of the wind turbine blade angle, namely 90˚, 95˚, 100˚. This research uses an experimental method with observation techniques, as well as measurement and recording as data collection techniques. This research was conducted on the Bung Tomo training ship for 3 days. The research results show that making a wind turbine using PVC as a base material costs Rp. 243,000.00 and produces the largest average voltage of 73.8 Wh. The influence of variations in the angle of the wind turbine blade can be seen that at an angle of 100˚ it has the largest average power output, namely 1.23 watts per minute and the battery charging time is based on an average current of 0.28 A, namely 12.5 hours when fully charged, whereas at The 90˚ angle produces the smallest average power of
0.76 watts per minute and the battery charging time is 16.6 hours when fully charged. So the 100˚ angle is more effective in charging the battery than the 95˚ and 90˚ angles. The greater the blade angle, the greater the rotation and produce greater voltage, this is influenced by the area of the turbine exposed to wind.

Published: September 2024

The brake block in the railway bogie system is an important component in supporting the operational safety of trains, so it needs to be inspected to determine its performance and service life. A simulation-based study was conducted to predict the wear rate of railway brake block with oriented braking force (F = 25.66 kN - 29.54 kN) and different material types, namely grey cast iron with hardness 170 HBN and metallic composite with hardness 90 HRR. The method of the study was carried out by Finite Element Analysis (FEA) simulation and calculating the wear rate with the Archard wear equation to measure the comparison of the amount of wear volume that occurs on the two materials. The results of the braking ability calculation can be concluded that the different types of brake block materials can affect the ability to decelerate during the deceleration process, causing differences in stopping mileage according to the type of material, such as gray cast iron (μ = 0.30) which has an average mileage of 15 metres and metallic composite (μ = 0.21) has an average mileage of 66 metres. The wear simulation results obtained are that the grey cast iron brake block has an average wear rate of 2,8285e-08 /s which is greater than the metallic composite which is only 1,5391e-08 /s. With this data, it can be concluded that oriented to the braking force load, the metallic composite brake block material has the advantage of a longer service life than grey cast iron.
