Investment is one of the activities that can provide benefits to several parties, such as for the progress of the company in running its business, even the development and growth of the economic sector in a country is also indicated by the number of investors who invest their funds or capital into securities companies in the capital market. Before investing in a company, investors will analyze companies that produce good stock returns, one of which is by analyzing the existing dividend policy in the company. This research was conducted to determine the effect of Profitability, Liquidity, Leverage, and Firm Size. The population using the Food and Beverage sub-sector companies for the 2017-2020 period amounted to 38 companies and the sample obtained was 10 companies using purposive sampling technique. The analysis in this study uses descriptive statistics, while hypothesis testing uses multiple linear regression. The results of this study indicate that there is a simultaneous influence between Profitability, Liquidity, Leverage, and Firm Size on dividend policy. Partially, only liquidity and firm size have a positive effect on dividend policy. Profitability and Leverage have no partial effect on dividend policy.

This study aims to determine the effect of capital structure, profitability and firm size on firm value. The population and sample in this study are the financial statements of 48 Food and Beverage Manufacturing Companies listed on the Indonesia Stock Exchange in 2018-2021. This research technique uses classical assumption test, multiple linear regression analysis, hypothesis testing and coefficient of determination test. The collection technique used the method of documentation and literature study. The results of the t-test (partial) can be seen that the first hypothesis which states that capital structure has a positive and significant effect on firm value is rejected. The second hypothesis which states that profitability has a significant positive effect on firm value is accepted. The third hypothesis which states that firm size has a significant positive effect on firm value is rejected. The magnitude of the coefficient of determination is 0.335 or equal to 33.5%. This value shows that the variables of Capital Structure, Profitability, and Company Size simultaneously affect the Company Value by 33,5%. While the rest (100% - 33.5% = 67.5%) is influenced by other variables outside this regression equation or variables not examined.

ABSTRACT

Alcohol is the common name for organic compounds that have a hydroxyl group attached to carbon and hydrogen atoms. The alcohol that is commonly found in liquor is ethyl alcohol or it is also called ethanol, but it is usually referred to as alcohol alone. Drinks with an alcohol content of 40% can lose consciousness, leading to accidents for alcohol-affected drivers. To detect alcohol in the body using an alcohol tester. Researchers tried to make a measuring instrument for alcohol levels in the body using several components such as Arduino nano, MQ 3 sensor, OLED, charger module, battery, resistor, push button, and buzzer. The design of a portable alcohol level detector through breath can work well, namely the results of the reading of alcohol levels in the body by the MQ-3 sensor through the breath and displayed on the Oled Display in units of% BAC (Blood Alcohol Concentration), in the sample comparison of the alcohol level reading between Final project tool with a comparison tool alcohol tester obtained the percentage difference in an average of 0.01% BAC.

Keywords: Alcohol, Arduino Pro Micro, MQ-3 Sensor, OLED, Charger Module, Battery, Resistor, Push Button, and Buzzer

Economic growth is a process of economic change that occurs in a country on an ongoing basis to lead to changes for the better over a certain period of time. The development of the Indonesian economy cannot be separated from the influence of various factors, including factors from abroad. Economic growth is influenced by several factors including exports, imports, fiscal deficits, and foreign debt. This study aims to determine the effect of exports, imports, fiscal deficits and foreign debt on economic growth in Indonesia for the 2017-2020 period. The sample selection in this study used the cluster sampling method because the objects and data sources to be studied were very broad, consisting of 34 provinces in Indonesia, the total data used was 680 samples. The data analysis technique used in this research is multiple linear regression analysis. The results of this study indicate that exports have a negative and significant effect on economic growth. Imports have a positive and insignificant effect on economic growth. The fiscal deficit has a positive and insignificant effect on economic growth. Foreign debt has a positive and significant effect on economic growth. Further researchers can also continue this research with a qualitative approach, where several variables that have no significant effect can be studied and analyzed by several key stakeholders who have a direct role in economic growth, so that further research models can be better.
