Abstract

This study aims to identify the electrolyte properties of various imported fruits through electrolysis experiments. A quantitative approach was used by measuring the presence of gas bubbles formed on electrodes as an indicator of electrolyte strength. Samples included apples, pears, grapes, lemons, mandarins, strawberries, cherries, kiwis, blueberries, and dates. The results showed that all tested fruit extracts exhibited electrolyte properties due to the presence of organic acids (such as citric, malic, and tartaric acids) and minerals that can ionize into free ions. Apples showed the strongest electrolyte activity, followed by pears, grapes, lemons, and mandarins, while cherries, kiwis, blueberries, and dates showed weaker conductivity. Electrolyte strength was influenced by factors such as ion concentration, acid type, and mineral content. These findings suggest that fruit extracts, especially those with higher acidity levels, have the potential to act as natural electrolytes and serve as an alternative source of environmentally friendly electrical energy.

Abstract

The purpose of this study is to determine the effect on income, health services and social services of employees at the Universitas Muhammadiyah Sumatera Utara or abbreviated UMSU. In the COVID-19 pandemic situation, many socio-economic impacts occurred on companies in the world, including at the UMSU as a higher education institution. This study uses primary and secondary data with quantitative descriptive analysis methods. This study took 12 respondents as samples from employees at UMSU by taking samples at the UMSU Administration Bureau. The results of the study concluded that income had a positive but not significant effect on welfare. Health services have a positive effect on welfare, while social services have a positive and significant effect on income. This research proves that the leadership of UMSU, in this case the Chancellor of UMSU, is very interested in maintaining the economy and employee immunity during the Covid 19 period which is currently engulfing the world.

Abstract

Debts are a common practice in daily life and are often considered trivial, especially if the amount is small. In fact, in Islamic teachings, debt is a mandate that must be fulfilled and has a moral responsibility for every individual. This research aims to find out students' views on debt practices that are considered trivial from an Islamic perspective. This study uses a quantitative descriptive approach with a survey method. The data was obtained through a questionnaire distributed online to students of the Chemistry Education Study Program, Faculty of Mathematics and Natural Sciences, State University of Medan. The data obtained is then collected and analyzed descriptively. The results of the study show that there are still views that consider small debts as not very important, even though in Islam every debt must still be accounted for.
