In response to the COVID-19 pandemic, single-use disposable masks saw a dramatic rise in production. Facial masks that are not properly disposed of will expose the environment to a form of non-biodegradable plastic waste that will take hundreds of years to degrade. Therefore, recycling such waste in an eco-friendly manner is imperative. Fibered or shredded waste masks can be used to make green concrete that is an environmentally friendly solution to dispose the facial masks. This study prepared six classes of concrete samples, three of which contained fibers from masks and three of which contained shredded masks at the ages of seven days and 28 days. The results show that in the seven-day and 28-day samples, mask fiber added to the mixes resulted in increased compressive strength. For seven-day and 28-day samples, the compressive strength increased by 7.2% and 10%, respectively. Despite that, the results of the shredded mask addition to concrete indicate that the increase in shredded mask volume has a minor impact on the compressive strength of the seven-day samples. An increase in shredded mask from 0.75 to 1% increased 28-day compressive strength by 14%. However, the compressive strength of the mask fiber decreased by 8 after 1% volume. According to a thermal analysis of 28-day concrete samples, as the fiber percentage increases, the mass loss percentage increases. The mass loss rate for samples containing fibers is higher than that for samples containing shredded mask pieces. In general, based on the results mentioned above, the use of fiber in concrete in its fiber state enhances its strength properties. As a result, using shredded mask pieces in concrete leads to better curing due to the reduction of residual capillary pore water loss in construction materials.

The purpose of this study was to determine the effect of brand image and promotion on decisions by using interest as an intervention variable. The method used in this research is the path analysis method. The sample used is 220 respondents. While the data collection by means of a questionnaire. The results showed that brand image did not have a positive and significant effect on interest. Promotion does not have a positive and significant impact on interest. Interest has a positive and significant influence on purchasing decisions. Brand image has a positive and significant influence on decisions. The promotion has a positive and significant influence on purchasing decisions. Interest is not able to mediate the effect of brand image on decisions as evidenced by the test results. Interest is not able to mediate the effect of promotion on decisions as evidenced by the test results.

The purpose of this study was to determine the effect of cash flow volatility, sales volatility, operating cycle, and firm size on the capital structure and earnings persistence of manufacturing companies in Indonesia. Based on the purposive sampling method, the samples obtained were 138 companies. The data collection technique in this research is literature study. The data analysis method used is multiple regression. The results showed that partially, the variables of cash flow volatility, sales volatility and firm size had a positive and insignificant effect on capital structure, the operating cycle had a negative and insignificant effect on capital structure. While the variables of cash flow volatility, sales volatility, operating cycle, firm size, capital structure have a negative and insignificant to earnings persistence of manufacturing companies on the Indonesia Stock Exchange.

This study aims to analyze the work environment, compensation, and supervision effect on job satisfaction and teacher performance at SMA Negeri 1 Kampar. This research is quantitative research by distributing questionnaires to respondents. The sample in this study were all teachers of SMA Negeri 1 Kampar totaling 63 people. The sample selection method in this study used the census, so the sample in this study amounted to 63 respondents. Data analysis using Structural Equation Modeling (SEM) using the SmartPLS 3 application. The results of this study indicate that the work environment has a positive and significant effect on job satisfaction, compensation has no significant effect on job satisfaction, supervision has a positive and significant effect on job satisfaction, and work environment has a positive and significant effect on teacher performance, compensation has no significant effect on teacher performance, supervision has no significant effect on teacher performance, and job satisfaction has a positive and significant effect on teacher performance.

This research aims to analyze the determinant of capital structure and profitability. Besides, it will also be tested to know whether there is a reciprocal relationship between this capital structure and profitability or not. The object of this research is using the registered manufacture company on the Indonesian Stock Exchange. The number of companies pointed as the samples in this research is 115 companies. The observation period is between 2012 – 2018 or for about 7 years so that the analysis units of this research are 805. The analysis tool used in this research is the Structural Equation Modeling by using generalized structural component analysis. It creates the results of Nondebt tax shield, effective tax rate, financial flexibility, liquidity; growth, uniqueness, assets utilization, firm size, tangibility, volatility, and profitability have an impact on the capital structure. It is known that only a firm age that doesn’t have any significant impacts on the capital structure. Liquidity, growth, firm age, uniqueness, firm size, tangibility, volatility, advertising, assets turnover, and capital affect profitability. Besides that, capital structure and profitability have a significant reciprocal relationship.
