Abstract

This study was conducted to examine the polarity and electrolyte properties of several types of imported fruit that are increasingly consumed by the Indonesian people after the Covid-19 pandemic. The method used was a laboratory experiment conducted using three types of polar-nonpolar solvents and a simple multimeter-based electrolyte circuit to measure conductivity by testing extracts of ten imported fruits (melon, dragon fruit, strawberry, kiwi, pomegranate, grapes, cherries, lemon peel, blueberries, and dates). The polarity test was carried out using three different solvents (water, vinegar, and cooking oil), while the electrolyte properties were observed with a simple electrical circuit. The results showed that most of the extracts were soluble in water and vinegar, but not in cooking oil, so the majority of the fruit components were polar. Lemon peel and melon peel have semi-polar properties due to their essential oil content. In the electrolyte test, fruits with high acid content (lemon, pomegranate, strawberry) act as strong electrolytes, while fruits with high sugar content (dates, melon) are only classified as weak electrolytes. Other fruits such as grapes, kiwi, and blueberries show moderate electrolyte properties. These findings support basic chemical concepts regarding the relationship between polarity, solubility, and electrical conductivity, and can be utilized in teaching and food technology applications.

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.
