Tire damage inspection can be categorized as part of vehicle maintenance with the aim of ensuring that the tire condition is in good condition. Visual inspection using human observation has limitations, making it not always accurate and can result in errors in determining tire suitability. This research designs a machine learning modeling using Convolutional Neural Network (CNN) to detect damage to mobile tires. The parameters used in the CNN model training are the Adam optimizer, learning rate 0.0001, batch size 16, and using the Early Stopping function. In this study, the CNN modeling was tested with two treatments, namely using a dataset without data augmentation and a dataset using data augmentation, then the results were evaluated using a confusion matrix. The results showed that data augmentation treatment can significantly improve model performance, with an increase in accuracy of 20%, precision of 14%, recall of 22%, and f1-score of 19% compared to treatment without data augmentation

Phase change materials (PCM) are materials that can change phase from solid to liquid and vice versa from water to solid. PCM is the most efficient material for storing heat energy in the form of latent heat. This study aims to investigate melting and freezing of PCM types of paraffin wax in pipes. The investigation was carried out in 3 experiments with heat source temperatures of 90 0 C, 85 0 C and 80 0 C. To facilitate investigation, paraffin wax is placed in a transparent tube. During the smelting process, observations were made for 600 minutes, and data recording and shooting were carried out every 60 minutes. The result is that the melting of paraffin wax starts from the top of the heat source side. The higher temperature paraffin wax moves upwards and the lower one moves downwards. On freezing, also found the same thing. The flow pattern is affected by the temperature of the paraffin wax itself. In addition, it can also be concluded that the higher the temperature of paraffin wax, the higher its ability to store heat energy .

The increase in global energy demand has driven the need for efficient solutions in selecting energy-efficient air conditioners (ACs). This research focuses on designing a web-based application as a decision support tool for choosing energy-efficient ACs. Energy-efficient labeled AC data is obtained from the Directorate General of New and Renewable Energy and Energy Conservation (EBTKE) website. This database is processed according to the system's requirements, where each AC brand is evenly represented to prevent dominance by a few brands. There are 11 different AC brands in this dataset, and each brand has 10 data samples. The web-based application is developed using the Python programming language with the Streamlit framework. This application allows users to compare various AC brands by considering power, annual energy consumption, efficiency value, and electricity cost. In the application design, users can select AC brands according to their needs, set the operating duration, choose the AC efficiency level, and select the inverter AC type. The application presents comparisons in the form of bar charts, making it easy for users to understand the differences in AC characteristics. The average results from the efficiency comparison of each AC brand reveal that Daikin achieves the highest efficiency at 16.36 Energy Efficiency Ratio (EER), while the GREE brand has the lowest efficiency at 5.83 EER. This application can assist consumers and industrial AC stakeholders in making decisions to choose energy-efficient ACs according to their needs.

In recent times, many studies have been carried out on desalination systems in areas that have difficulty in obtaining clean water sources. Desalination is a method used to distill salt water or brackish water into clean water using solar power as its energy source. This desalination process is a practical alternative that can be used to offer renewable energy sources that are used to produce clean water. To perform energy analysis, the first law of thermodynamics is used as a basis. This study aims to obtain the results of the amount of energy obtained from the solar desalination system and to determine the factors that greatly affect the amount of energy obtained from the system for evaporating water. The method used in this research is an experiment by testing a solar desalination device for eight days. The results show that the highest thermal energy produced is 8.98 kWh and the lowest is 1.56 kWh, and the factors that influence the amount of thermal energy are the heat transfer coefficient and the amount of distilled water produced by the system.

The inner tube determines the effectiveness and efficiency of a commercial transportation vehicle, where the inner tube is expected to have high durability against friction with the outer tire and to have high tensile stress when holding a heavy load. To answer this condition, the process of adding natural rubber material to the inner tube was carried out using the pressure method with 2 variables, namely one layer of inner tube and one layer of natural rubber which was affixed to the outer side of the inner tube, as well as one inner tube with two layers of natural rubber located on the side outside and inside on the inner tube. Then the testing process is carried out, namely tensile brake and hardness to obtain data to determine the effect of adding natural rubber to the inner tube using the pressure method as one of the references for producing better inner tubes. After the research process was carried out, the results of the tensile brake test were 20.4 Kgf on the first specimen, 23.8 Kgf on the second specimen, 31.05 on the third specimen. Furthermore, from the hardness test, a result was obtained, namely 52° on the first specimen, 48° on the second specimen, 44° on the third specimen.

Fenders are structures installed on the edges of ships to protect the ship's hull from impact with the dock. The main function of fenders is to absorb the collision energy generated by the ship's impact during berthing at a dock. The load applied to fenders on each ship results in stress distribution in the surrounding hull area, which can lead to various issues such as damage, cracks, deformations, and others. Additionally, the presence of fenders with different shapes can affect the stress distribution values in the surrounding hull area. Hence, a local stress analysis using finite element method software is necessary. The analysis focuses on static loads originating from the ship itself when docked at a port. However, only the fender section is analyzed, and it is not necessary to consider the entire ship's body. The objective of the analysis is to determine the stress characteristics and maximum stress values in the fender itself. The analysis results reveal that the highest stress value occurs in the half-pipe-shaped fender with a value of 0.22809 MPa. Based on these findings, it can be concluded that the stress values in the fender meet the allowable standards. In conclusion, this analysis provides an understanding of stress and the maximum stress value in ship fenders. This knowledge is crucial to ensure that fenders effectively fulfill their function of protecting the ship from impacts with docks.

The brake pad is a critical component in the LRV braking system. Based on maintenance data on the LRV Series 1100 shows that there is a decrease in the thickness of the brake pad. The braking system on the LRV has two types of braking, which are regenerative braking and pneumatic braking. Regenerative braking is a braking system that works by utilizing kinetic energy in motor traction. Pneumatic braking is a braking system that works by utilizing compressed air which moves the calipers and is forwarded to the brake pads to grip the disc brakes. The purpose of this study is to determine the wear rate of the brake pads so that the prediction of the service life of the brake pads is known and to find out the factors causing the differences in the wear rates of the brake pads attached to the bogie trailer and the bogie motor. The method used in this study is linear regression, by processing maintenance data and collecting data in the field so that the factors that influence the wear rate and differences in the rate of wear on the brake pads are obtained. After analyzing the data, the brake pad on the McA bogie brake pad can be achieved in November 2039 with a thickness of 8.06 mm, the McB bogie in June 2042 with a thickness of 8.03 mm, on the trailer bogie in November 2029 with a thickness of 8.12 mm. The braking force between the brake pad and disk brake on the McA and McB bogies was 98.26 kgf, the braking friction that occurred had an impact on the wear rate of the McA and McB bogie brake pads which was 1.11 x 10-6 mm3/Nm. Whereas in the bogie trailer, the braking force between the brake pad and disk brake is 25.24 kgf, the braking friction that occurs affects the brake pad wear rate of 10.01 x 10-6 mm3/Nm. The factors that affect the difference in wear rate are the regenerative braking function and the pneumatic braking itself, on bogies McA and McB brake pads work at speeds of 15 km/h to 0 km/h, while on bogie trailers from a maximum operating speed of 60km/h to 0 km /j uses the pneumatic braking function.

Currently, the area of oil palm plantations in Indonesia is increasing. However, the condition of oil palm plantations generally has very minimal infrastructure. Therefore, a means of transporting palm fruit is needed that can move in plantation areas that have minimal infrastructure and have the ability to turn with a small turning radius. Chassis is the most important component in every vehicle. Chassis is a component used to support the load, vehicle body, engine, and driver. The development of technology in the field of engineering requires the chassis design of a vehicle to be light but strong. Therefore, this study aims to analyze the strength and safety factor of the chassis using the Finite Element Method. The software used in this analysis is SolidWorks 2018. By doing this analysis, the safety factors in the chassis design will be known. In this design, the magnitude of the factor of safety must be more than two. 3D modeling and material data are required to run the simulation of strength and factor of safety analysis. The material that will be used in the design of this chassis is ASTM A36 steel. From this research, it is expected that the chassis can withstand a maximum load of 500 kg and a maximum driver of 100 kg. From this research, it is expected that the chassis can withstand a maximum load of 500 kg and a maximum driver of 100 kg. From the simulation results using the SolidWorks 2018 software, it can be seen that the safety factor results when accelerating are 3, braking are 3.4 and when turning are 4.2. So it can be concluded that the chassis design is certainly safe.

Therefore, a means of transporting palm fruit is needed that can move in plantation areas that have minimal infrastructure and have the ability to turn with a small turning radius. Chassis is the most important component in every vehicle. Chassis is a component used to support the load, vehicle body, engine, and driver. The development of technology in the field of engineering requires the chassis design of a vehicle to be light but strong. Therefore, this study aims to analyze the strength and safety factor of the chassis using the Finite Element Method. The software used in this analysis is SolidWorks 2018. By doing this analysis, the safety factors in the chassis design will be known. In this design, the magnitude of the factor of safety must be more than two. 3D modeling and material data are required to run the simulation of strength and factor of safety analysis. The material that will be used in the design of this chassis is ASTM A36 steel. From this research, it is expected that the chassis can withstand a maximum load of 500 kg and a maximum driver of 100 kg. From this research, it is expected that the chassis can withstand a maximum load of 500 kg and a maximum driver of 100 kg. From the simulation results using the SolidWorks 2018 software, it can be seen that the safety factor results when accelerating are 3, braking are 3.4 and when turning are 4.2. So it can be concluded that the chassis design is certainly safe.","PeriodicalId":53345,"journal":{"name":"Jurnal Energi Dan Manufaktur","volume":"55 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2023-07-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"83342303","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}

Pertamax has the advantage of the pertatec compound protecting the engine from rust. In Pertamax fuel with an octane rating of 92 it works optimally and the rest of the combustion results. Meanwhile, an engine with a lower octane rating has the impact of burning fuel that explodes and has a risk of misalignment causing knocking symptoms. This research includes comparative research with experimental methods. The test results for a single injector (12 holes) have increased compared to a double injector (12 holes). 10.86 and on the double injector (12 holes) which is 12.25 so that the acceleration on the single injector is better than the double injector, the single injector (12 holes) which is 30.15 Kph/s and the double injector (12 holes) which is 29.37 Kph/s, resulting in greater torque and power values, namely single injector (12 holes) of 9.71 Nm and power of 10.19 HP and double injectors (12 holes) of 9.7 Nm and power of 8. 97 HP with the greatest speed obtained single injector (12 holes) 103.91 Km/h and Double injectors (12 holes) 103.68 Km/h. So that a single injector with 12 holes is better used on 110 cc vehicles seen from the aspect of the Dynotest.
