Abstract

The study aims to analyze the effect of liquidity and activity on profit growth as mediated by capital structure. The study population comprises of 92 companies operating in the food and beverage sector that are listed on the Indonesia Stock Exchange for the 2023 period. Data for this study were collected from secondary sources, specifically the official website of the Indonesia Stock Exchange (https://www.idx.co.id). The data were analyzed using the Partial Least Squares (PLS) structural equation modeling technique, supported by WarpPLS version 7.0 software. The results indicate that liquidity negatively affects profit growth, while activity and capital structure have no significant impact on profit growth. Furthermore, capital structure does not mediate the relationship between liquidity and profit growth, nor between activity and profit growth. These findings imply that optimal liquidity management is crucial for enhancing profit growth, and that efficient operational activities contribute positively to overall company performance.

Abstract

This study investigates the effect of capital structure on profitability with liquidity as a moderating variable in food and beverage companies listed on the Indonesia Stock Exchange during 2019-2023. Using a quantitative approach, this study uses secondary data from 26 companies selected by purposive sampling. Profitability is measured using return on assets, return on equity, and net profit margin, while capital structure and liquidity are represented by debt to equity ratio and current ratio. The study applies panel data regression and moderated regression analysis using Eviews 13. The novelty of this study lies in explicitly integrating liquidity as a moderating variable in the relationship between capital structure and profitability, which has hardly been addressed in previous studies. The findings show that capital structure has a negative effect on return on assets and net profit margin but has a positive effect on return on equity. Liquidity does not significantly moderate the effect of capital structure on return on assets and net profit margin; however, it significantly moderates the relationship with return on equity, indicating that high liquidity may weaken the positive effect of leverage on shareholder returns. This study concludes that capital structure decisions should consider liquidity conditions to ensure sustainable profitability, especially in industries with operating cash flow volatility. Future research is recommended to explore non-linear relationships and use broader financial indicators to strengthen the generalizability of findings across sectors.

Abstract

Nosocomial infections in postoperative patients are a serious problem in hospitals because they can increase the rate of illness, death, and treatment costs. One of the important steps in controlling these infections is to conduct an Antibiotic Sensitivity Test to Bacteria in the Postoperative Treatment Room at Royal Prima Marelan Hospital to determine the effectiveness of drugs against bacteria causing infection. This study aims to identify the types of bacteria found in the postoperative intensive care room of Royal Prima Marelan Hospital and assess the level of sensitivity to several antibiotics. The study used an observational descriptive design with a cross-sectional approach. A total of 10 samples were taken from air, wall surfaces, floors, beds, and medical equipment. Bacterial identification was carried out through culture and Gram staining, followed by sensitivity tests using the Kirby-Bauer method against the antibiotics levofloxacin, amoxicillin, and tetracycline. The results showed that the most common bacteria found were Bacillus sp. (60%), followed by Staphylococcus sp. (30%), and Streptococcus sp. (10%). Sensitivity tests showed that levofloxacin had the highest sensitivity level at 90%, amoxicillin sensitivity was 70% with 30% resistance, while tetracycline showed a balanced result between sensitive and intermediate at 50%. Based on these results, levofloxacin is still the most effective antibiotic against bacteria in the postoperative room, while amoxicillin and tetracycline are less effective. These findings are expected to support the selection of appropriate antibiotics and help control bacterial resistance in hospitals.

Abstract

The surface roughness of a machining process is a very important factor in the field of production that is one of the turn-milling process. Turn-milling is a combined machining process of turning and milling with complete tools (cutting) where workpieces and tools rotate together. The turn-milling process can generally be categorized in orthogonal turn-milling, tangential turn-milling and co-axial turn-milling methods. The resulting surface quality is also affected by the parameters of the machining process in the form of rotation of the workpiece and the rotation of the tool. The purpose of this research is to know the effect of parameters on surface roughness and optimal parameter to surface roughness by doing tangential process of turn-milling. By varying the parameter variables, the surface roughness generated in this study is influenced by the rotation of the workpiece and the rotation of the tool. The higher the tool rotation the lower the surface roughness. Conversely, the higher the rotation of the workpiece the higher the surface roughness. The optimal parameter is a rotation tool of 25000 rpm with a rotation of 630 rpm objects found in the roughness class N7 with a roughness value of 1.321 μm where the roughness value is lower among other N7 roughness classes.Keywords : Turn-milling, Tangential Turn-milling, Rotation, Roughness.

Abstract

The turn-milling test has three methods in the process of working are orthogonal, tangential, and co-axial. In this methods turn-milling test produces a varied surface roughness. To optimize the surface roughness in this method orthogonal turn-milling then the variation of testing is done at the rotation velocity of workpiece and feeding velocity. The testing process of turn-milling machining is performed on conventional lathe with the addition of a rotary tool. The purpose of this research is to get the optimum rotation velocity of workpiece and feeding velocity of the value of surface roughness and To know the effect of velocity rotation of workpiece and feeding velocity to surface roughness value. With increasing velocity rotation of workpiece and feeding velocity, velocity rotation of the workpiece increased will affect the surface roughness value. Based on the roughness class N, the 630 rpm rotation of workpiece parameters with feed rate of 0.060 mm is a good parameter in this study because it produces a roughness value of 1.489 μm lower than the other test.Keywords : Turn-milling, Round, Feeding, Roughness.
