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.
