Abstract

The research aims to determine the effect of capital structure, profitability and company size on company value in food and beverage sub-sector companies listed on the Indonesian Stock Exchange (BEI) from 2021 to 2023. In this research the independent variable used is capital structure. using Debt to Equity Ratio (DER), profitability using Return on Assets (ROA), and company size using natural logarithm (Ln) of total assets, and the dependent variable, namely company value using modified Tobin's Q. The population in this study was 95 food and beverage sub-sector companies. The sample was selected using a purposive sampling method with predetermined criteria so that 44 companies were collected over 3 years, resulting in 132 research samples. The data used is secondary data in the form of financial reports obtained from the website www.idx.co.id, measured using SPSS research tools. The results of this research reveal that capital structure has a significant negative effect on company value, profitability has an insignificant positive effect on company value, and company size has an insignificant negative effect on company value.

Abstract

Welding is one of the essential processes in the manufacturing industry. One of the factors that affects the quality of welding results is the cooling medium used after the welding process. This study aims to determine the effect of different cooling media on the tensile strength of SMAW (Shielded Metal Arc Welding) welded joints on ASTM A36 steel. Three types of cooling media were used air, water with a pH of 6.5–8.5 and SAE 10W-40 oil. The welding process was carried out using an I-groove with a butt joint in the 1G position, using an E7018 electrode with a diameter of 3.2 mm and a current of 100 A. The tensile tests were conducted according to the ASTM E8 standard.The results showed that the specimens cooled with SAE 10W-40 oil produced the highest average tensile strength of 574.9974 Mega pascal and the highest average elongation of 38.73%. Cooling with water resulted in an average tensile strength of 566.5932 Mega pascal and a maximum elongation of 28.27%. Meanwhile, cooling with air resulted in the lowest average tensile strength of 545.5592 Mega pascal and an elongation of 30%. The highest modulus of elasticity was obtained from water cooling at 2051.55 Mega pascal, followed by air at 2048.60 Mega pascal, and the lowest was from oil at 1493.83 Mega pascal.Based on these results, it can be concluded that the variation of cooling media affects the tensile strength of welded joints. Cooling with SAE 10W-40 oil provided the most optimal results, producing the highest tensile strength and good ductility. Therefore, SAE 10W-40 oil is recommended as the best cooling medium for the SMAW welding process on ASTM A36 steel, especially in ship hull applications. Keywords: SMAW, ASTM A36 Steel, cooling media, tensile strength, I-groove, butt joint, ship hull.
