Abstract

The Praktik Pengalaman Lapangan (PPL) program is an effort to introduce prospective teacher students to the world of their profession. Praktik Pengalaman lapangan is one of the best programs of the Faculty of Teaching Education (FITK), Sains Al-Qur’an University in providing opportunities for its students to practice teaching directly in the field. The research is used a field research in qualitative. Qualititative is a type of research that is observing an object then data was analyzed using descriptive. This research was used questionnaire of student response to collect the data. The data of this research were analyzed using descriptive and student response. Based on the data analysis carried out, it was concluded that students had very good science teaching abilities based on the assessments of lecturers and teachers, as well as good based on student assessments of the learning process carried out by UNSIQ PPL students majoring in physics education.

Abstract

Electric stoves with the concept of electromagnetic induction use coils to generate magnetic fluxes that can conduct heat. This study aimed to determine how induction-based electric stoves work and the effect of working coil variants on the electromotive force of induction and the temperature of water when cooked. The research method used was an experiment with data analysis using simple and multiple linear regression. The results showed that induction-based electric stoves utilize eddy currents that arise when a ferromagnetic conductor material is placed in the working coil, thus producing heat for cooking. The effect of the working coil on the electromotive force of induction and the temperature of water when cooking uses three working coil variants, namely enamel wire with a diameter of 0.5 mm with a length of 80 m, a diameter of 0.5 with a length of 112 m and a diameter of 1.5 mm with a length of 8 m. After testing, the results showed that the coil variant with a diameter of 0.5 mm and a length of 80 m had a strong influence on the induced emf, and the coil variant with a diameter of 0.5 and a length of 112 m had a substantial impact on the temperature of the water when cooked. This study implies that optimizing the coil configuration, such as using a 0.5 mm diameter enamel wire with a length of 80 m for the induced electromotive force and a 0.5 mm diameter wire with a length of 112 m to increase the water temperature, can improve the efficiency and performance of induction-based electric stoves.
