Abstract

Bucket teeth are an important component of an excavator that functions as a material penetrator or digger. This part is prone to failure because it is in direct contact with the ground. This study aims to determine the value of stress, strain, deformation, and safety factors that occur in the Komatsu PC400 excavator bucket teeth against thickness variations of 2.5 mm, 5 mm, 7.5 mm, and 10 mm. This study uses a computer with specifications: processor: Intel (R) Celeron (R) N4000 CPU @ 1.10 GHz, memory: 8 GB. Windows 10 Home Single Language 64-bit Operating System. This computer is equipped with Autodesk Inventor Professional 2023 and ANSYS Workbench R1 2023 software. The method used in this research is a testing method using ANSYS software with a finite element method approach, namely static structural. The simulation results of bucket teeth show the maximum deformation values are 0.16382 mm, 0.13832 mm, 0.1249 mm, and 0.11619 mm, respectively. Furthermore, the maximum equivalent stress values are 108.6 Mpa, 79.712 Mpa, 80.338 Mpa, and 79.992 Mpa, respectively. For the equivalent elastic strain maximum, 0.00052993, 0.00038899, 0.000392, and 0.00039029 were obtained. Then the safety factor value is obtained 3.8214, 5.2062, 5.1657, and 5.188. This shows that the thicker the thickness variation, the better the strength value.

Abstract

The process of making cement goes through numerous phases and different procedures in order to produce cement that is up to factory requirements. In addition to the combustion process, the cooling process also exists in the cement manufacturing kiln area, particularly the rotary kiln, but it is less crucial. A crucial aspect of the cement production machinery is the cooling procedure or clinker cooler. The cooling process here impacts the quality of the cement produced, therefore this equipment is used to cool or lower the temperature of the clinker so it doesn't burn in the rotary kiln. The relationship between the clinker's crystal concentration and the liquid phase is influenced by the rate at which the clinker cools

Abstract

In Indonesia, the number of motor vehicles using fuel as an energy source is rising quickly. The government has developed renewable energy to reduce fuel consumption because, according to the Downstream Oil and Gas Regulatory Agency (BPH Migas), the consumption of gasoline-type fuels in 2017 was 1,858,875 L/Quarter. Determining the impact of using bioethanol with different injection times on exhaust gas emissions was the aim of this study. Bioethanol is an environmentally friendly alternative fuel for cars that uses less fuel. It is a renewable energy source made from vegetable sources. Variations in fuel injection duration and exhaust gas emission are the main subjects of this study. With no modifications to compression, the engine operates under standard conditions. A gas analyzer and engine speeds of 1500, 2000, 3000, 4000, and 5000 Rpm were used in the study. According to the study's findings, the amount of CO exhaust gas dropped. At 5000 RPM for 4 ms, the lowest CO in bioethanol fuel is 1.21%. With bioethanol fuel, the amount of HC exhaust gas emissions has dropped. 710 ppm at 3000 Rpm for 4 ms is the lowest HC level. When using bioethanol as fuel, the amount of CO2 emissions rises. The maximum CO2 concentration is 6.50% at 5000 RPM for 4 ms. The maximum amount of O2 emissions from bioethanol fuel is recorded at 1500 RPM for 4 ms.

Abstract

The use of excavators across industrial and mining sectors is critical, particularly for bucket tooth components that perform penetration and excavation. These components often undergo wear and tear due to repeated stress and abrasion. This study aims to analyze the influence of variations in bucket tooth notch types on stress, strain, deformation, and safety factors using the Finite Element Method. The variation of standard, elliptical, and diamond notch types in the Komatsu PC200 bucket tooth model was designed using Autodesk Inventor Professional 2025. The simulation results show that the elliptical notch type has a maximum stress value of 6.2893 MPa, a maximum strain of 0.000036465 ul, and a maximum deformation of 0.00266049 mm, which is better than the standard and diamond types. Meanwhile, the diamond type has the highest maximum stress of 7.8416 MPa and the lowest deformation of 0.00259299 mm. The highest safety factor was found in the elliptical type (6.91635), which indicates that this design is safer to use in heavy workload conditions. The results of this study show that the elliptical notch type design is more efficient and has the best resistance to workload, so that it can improve the service life and performance of bucket teeth. The applied load represents a static reference for comparative evaluation among geometries; therefore, the results reflect relative design performance.

Abstract

Nowadays, many Indonesian commonly use metal trapezoidal corrugated roofs for their residential needs. Nevertheless, the roofs often deformed or failed due to heavy rains or storms, especially in tropical regions like Indonesia. Therefore, a new model was investigated and proposed in this research to enhance the stiffness-to-weight ratio of the roofs. Computational simulation was conducted to compare the existing and the proposed model of the roofs. The addition of some small folds in certain positions successfully increases the stiffness-to-weight ratio of the roof by 11.58% compared to the existing model.

Abstract

This research focuses on manufacturing composite wings using the vacuum bag process. The vacuum bag method is used because it can reduce manufacturing time and improve the quality of the final product. This study aims to determine the impact of the vacuum bag method on the geometry between the design stages and the final results of the UAV wing. Differences in design geometry and final results are calculated by measurement. The effects of variations in thickness and loading were estimated by modeling simulations with Fusion360 Software. The geometry of the design stage and the final result did not have a significant change, with a difference of 10% in thickness, 2.45% in wing length, and 0.80% in wing width. For deformation, it can be concluded that the increase in thickness and loading is directly proportional to the magnitude of the deformation that occurs. The greater the value of thickness and loading, the greater the deformation that occurs.

Abstract

To create briquettes, the raw materials are compressed using a variety of pressing pressures. Briquette presses come in two popular varieties: vertical and horizontal. Briquettes are often made from non-hazardous home waste and agricultural biomass, offering a premium and sustainable alternative energy source. The goal of this study was to use a hydraulic press-type briquette press method to improve the shape properties of the briquettes. The ingredients employed in this investigation were water, tapioca, wood dust, and rice husk. The composition of the briquettes is 40% rice husk, 40% sawdust, 10% tapioca, and 10% water. A hydraulic press machine with a maximum pressure of 30 Psi was utilized in the briquette press method. This study will examine each mold's density, drop test, water resistance, and burning rate. According to this study, triangular briquettes have the lowest briquette burning rate value (0.1 g/min), the lowest impact resistance value (0.67%), the slowest burning rate value (0.1 g/min), which indicates longer burning, and the highest value (0.9696 g/cm³), which indicates a denser and more solid structure. According to the findings of the test criteria that researchers have conducted, triangular briquettes are recommended.
