Abstract

This research aims to analyze the effect of the comparison of the temperature of the cooling medium used in the cooling process of medium carbon steel welded using a SMAW welding machine to the hardness values. The cooling medium used is SAE 5W 30 oil with different temperatures of 80°C, 90°C, and 100°C. The research was carried out by using the method of welding on medium carbon steel and cooling it with oil media at different temperatures, then testing the Vickers hardness with a load of 40 kgf. Researchers used oil cooling media without heating, and room temperature as a differentiator, as a result, through this research, generally different results were obtained, namely the hardness number of non-media materials 103, 584972 VHN, oil without heating 108, 127134 VHN, oil 80°C 108 , 36668 VHN, 90°C 110 oil, 5910479 VHN, 100°C 101 oil, 4692936 VHN.

Abstract

This article aims to analyze the development of Artificial Intelligence (AI) research in the context of vocational education. The study employs content analysis, evaluating vocational education journals sourced from the Sinta database. The research findings indicate that AI research in vocational education remains limited. Its applications in vocational education include the development of information systems and websites, learning media, improvements in the learning process, learning strategies, and assessment methods.

Abstract

The massive use of fossil energy will cause a buildup of CO2 gas from combustion. The Indonesian government is targeting the use of renewable energy as a solution. The renewable energy source that can be chosen is solar energy. However, the use of solar panels requires a plan so that they can operate optimally according to the conditions of the installation area. Therefore, it is necessary to study the use of solar panels on the roofs of buildings as a concrete manifestation of meeting the set targets. In this research, an analysis of electrical energy needs was carried out in Building A of the Batulicin Polytechnic (Polibali), and a simulation of the use of solar panels on the roof of Building A Polibali was conducted to obtain system specifications that could be built. The method used is a direct measurement of electricity usage data in Building A Polibali and a simulation of electrical energy that can be produced from installing solar panels using premium PVSol software. Considering the roof area, 180 solar panel modules were selected with a power rating of 285 W per module and a tilt angle of 15 degrees, so that the simulated system power was 51,3 kWp. The results obtained show that the planned production of electrical energy from solar panels can exceed the overall electricity consumption needs of Building A Polibali, which is 26,512.9 kWh per year, with production from solar panels of 75,217 kWh per year.
