The Influence of Working Capital Turnover and Debt to Equity Ratio on Return on Asset

The Covid-19 pandemic in 2020 caused the performance of the pharmaceutical subsector to fluctuate. From these results, it can be seen that the Return on Assets of pharmaceutical subsector companies has decreased and Working Capital Turnover has also decreased. The low working capital turnover was due to a decrease in current assets and an increase in current debt used to finance company projects. A low working capital turnover ratio means that working capital processing is not running well, whereas a high working capital turnover ratio means that the company's working capital is functioning effectively. This research aims to know the influence of Working Capital Turnover and debt-debt-equity ratio on Return on Assets in companies' subsector pharmacy period 2017-2022. Data analysis techniques used that is analysis Descriptive and Verifiable using the Assumption Test Classic, Multiple Linear Regression Test, Analysis Coefficient Correlation, Analysis Coefficient Determination, and Hypothesis Testing. The results of this research show that the Working Capital Turnover Variable has partially no influence on the Return on Assets and the Debt to Equity Ratio variable has Partial influential negatively on the Return on Assets Overall Simultaneous Working Capital Turnover and Debt to Equity Ratio affect the Return on Assets

CARBON ADSORBENT PREPARED FROM WASTE MATERIALS FOR LPG GAS STORAGE MEDIA

Coconut shell and oil palm shell are an agricultural waste material found abundantly in Malaysia. Since the characteristics of coconut shell and oil palm shell were found suitable for preparing activated carbon, these materials also have the potential to be prepared into useful and valuable product. This research, the concern is to make use of coconut shell or oil palm shell which it mixed with plastic bag to prepare the carbon adsorbent, which applied for hydrocarbon gas storage. This sample was prepared at a laboratory scale fixed-bed reactor, which is blanketed by a vertical furnace where pyrolysis took place. Nitrogen gas was used to obtain an inert atmosphere in the reactor. A suction blower was used to remove volatile matter as well as other gases during carbonization process. The samples were prepared in the different peak temperature and amount of the plastic bag which it mixed with them. CO2 activation also was used to investigate the effect of it in the sample. This research work will attempt to find a suitable solution to solve the environmental problems by utilizing the waste materials and to look into the industrial aspect of adsorption process for gas storage

Design optimization of a fixed bed biomass gasifier of a two stage incinerator

Waste wood, a renewable energy source is used as feedstock for Universiti Teknologi Malaysia’s newly-developed two-stage incinerator system. The research goals are to optimize the operation of the thermal system, to improve its combustion efficiency and to minimize its pollutants formation. The work focuses on one of its components, i.e. the primary chamber which comprises of a large updraft fixed-bed chamber, measuring 187.5cm in height and 194.5 cm in diameter respectively. During experimental work, the primary chamber is fed in batches of the processed feedstock while the air for combustion is metered through an eight air nozzle supply system, incorporated at the lower side of the tapered chamber. The feedstock will undergo four different processes; drying, devolatilisation, gasification and combustion. The combustion process is evaluated with the variation of fuel’s moisture content, i.e. set at 17%, 31%, and 40% respectively. The initial experimental work indicates that the temperature and oxide of nitrogen (NO) concentration are decreased with the increase of the moisture in the fuel. Furthermore, the concentration of carbon monoxide (CO) increases with the variation of this operating parameter. However the change for carbon dioxide (CO2) and oxygen (O2) concentrations are only around 1% with the variation of this operating parameter. For optimum operating condition, where the gasification efficiency is 95.53%, the moisture content of the fuel is best set at 17%; giving outlet operating temperature of 550oC and exhaust gas concentrations with 1213 ppm of CO, 6% of CO2, 66 ppm of NO and 14% of O2 respectively. In parallel to the experimental work, a computational fluid dynamics software is used to simulate the performance of the primary chamber at optimum operating condition. This technique provides detail insights on the dynamics of flow and the combustion behavior that occur in the reference chamber. A steady state model is formulated for the updraft fixed bed reactor. Here the predicted optimum gasification efficiency stands at 95.49% with CO, CO2, NO and O2 concentrations as 1301 ppm, 6.5%, 53.7 ppm and 13.5% respectively. The major amendment to the chamber design is proposed on the aspects of air-exit-velocity, i.e. by using smaller diameter of the air nozzles. In doing so, it will create high air-jet penetration in the combustion zone. Higher combustion temperature above 850oC is created for the gasification and combustion zones. This will also reduce NO formation from 54 ppm to 25 ppm at the exit point of the chamber

Thermal performance of optimized interrupted microchannel heat sink (IMCHS) using nanofluids

An interrupted microchannel heat sink (IMCHS) using nanofluids as working fluids is analyzed numerically to increase the heat transfer rate. The rectangular IMCHS is designed with length and width of 10mm and 0.057mm respectively while optimum cut section number, n c=3. The three dimensional governing equations (continuity, momentum and energy) were solved using finite volume method (FVM). Parametric study of thermal performance between pure water-cooled and nanofluid-cooled IMCHS are evaluated for particle diameter in the range of, 30nm to 60nm, volume fraction in the range of, 1% to 4%,nanofluid type of Al 2O 3, CuO, and SiO 2 at Reynolds number range of 140 to 1034 are examined. The effects of the transport properties, nanofluid type, nanoparticle volume fraction and particle diameter are investigated on the IMCHS performance. It is inferred that the Nu number for IMCHS is higher than the conventional MCHS with a slight increase of the pressure drop. It is found that highest thermal augmentation is predicted for Al 2O 3, followed by CuO, and finally for SiO 2 in terms of Nu nf/Nu pw in the IMCHS. The Nu number increased with the increase of nanoparticle volume fraction and with the decrease of nanoparticle diameter

Analysis of the Profitability of Agricultural Sector Companies - Sub-Sector of Agriculture Listed in Indonesia Stock Exchange

This study aims to analyze the profitability of plantation sub-sector companies listed on the Indonesia Stock Exchange (BEI), based on the analysis of Gross Profit Margin (GPM), Nett Profit Margin (NPM), Return On Asset (ROA), and Return On Equity (ROE). The data used in this research is secondary data in the form of financial statements of Plantation Sub-Sector Companies listed on the Indonesia Stock Exchange (IDX) for the period 2014-2018, which were obtained from www.idx.co.id. The method used in this research is the descriptive analysis based on quantitative/financial analysis. The results showed that companies with higher Total Assets and Total Equity have the potential to achieve better Total Revenue, thus supporting the achievement of better Earning After Tax (EAT). However, these conditions do not necessarily guarantee that the company will achieve the best Gross Profit Margin (GPM), Nett Profit Margin (NPM), Return On Asset (ROA), and Return On Equity (ROE) as well, given the best Gross Profit Margin (GPM), Nett Profit Margin (NPM), Return On Asset (ROA) and Return On Equity (ROE) are financial ratios whose measurements are influenced by the width of the range or margin among other financial measures that underlie the calculation of these ratios
