The inspection and testing of the vertical pressure vessel at PT. X were conducted to assess its structural integrity and ensure operational safety. The study focused on thickness and hardness measurements, along with computational stress analysis using the Finite Element Method (FEM). The results revealed an average material thickness of 4.98 mm and an average […]
Dissimilar aluminum alloys welding between AA5xxx and AA6xxx presents significant challenges due toifferences in chemical composition, thermal properties, and electrochemical potential, all of which impact the corrosion resistance of the welded joints. AA5xxx alloys are well-known for their excellent corrosion resistance, particularly in marine environments, while AA6xxx alloys exhibit superior mechanical strength. This study provides
Jakabaring PLTS on-grid with a capacity of 2 MW operates from 6:00 am to 5:00 pm. At 5:00 pm the PLTS connection to the load will be disconnected and replaced with PLN. If the PLN is off due to damage or during maintenance, a generator that is operated manually will be used. Problems in the
The performance of an automatic transmission is dependent on the dynamics of its components, such as the clutch, planetary gear, and torque converter. In particular, the clutch pressure and planetary gear output speed can affect the overall performance of an automatic transmission. In this paper, It will present the kinematic relations, the dynamics of planetary
This study aims to analyze the parameters that actively affect the efficiency of gas power plants in order to optimize their performance. The method used in this study was an analytical approach based on the results of performance tests conducted in 2018, 2020, and 2022 on gas power plants in the sumatera selatan area, based

Earthquake is natural event due to release of energy suddenly from within that creates seismic waves. The vibrations are usually caused by movement of earth’s plates. It cannot be predicted when they are coming. Therefore, need to build an early warning system. It is for anticipation of save the community when an earthquake occurs. It
Along with the increasing problem of oil price volatility, vehicles with alternative fuels are the right vehicles to use at this time. Electric bicycles are one of the vehicles that use alternative fuels. Electric bicycles use battery power as a power source. Electric bicycles consist of two main parts, namely bicycles and electrical components. Bicycles
Financial problems are one of the very vital problems for the company in the development of business in all companies. The evaluation carried out by the company must begin with analyzing each data on the financial statements by comparing the post per post or period one with another. This evaluation uses the analysis of financial

This study aims to identify the effect of infill on mechanical behaviour, especially the yield stress and modulus young of polylactide materials with different unit cell structures such as gyroid, diamond, square, and re-entrant but same porosity with value of 60%. Using Computational aided design (CAD) software and analyzed using the finite element method. The
Nowadays, reducing fuel consumption and greenhouse gases are top priorities for automotive manufactures because of environmental hazards and running out fossil fuels all over the world. These reasons are the key factors that lead to the creation of hybrid cars. This article discusses the intervention in hybrid vehicle’s content parameters, which were conducted on the
