Abstract

Telah dirancang sebuah perangkat sumber pembangkit energi listrik berbasis piezoelektrik pada sepatu untuk pendaki gunung. Piezoelektrik digunakan untuk memperoleh energi listrik yang dihasilkan dari adanya tekanan. Energi listrik yang dihasilkan lalu disimpan pada baterai litium 3,7 V yang sebelumnya disearahkan dari arus AC (Alternating Current) ke arus DC (Direct Current) menggunakan dioda penyearah. Hasil tegangan input listrik kemudian ditampilkan pada LCD (Liquid Crystal Display) yang datanya diolah menggunakan mikrokontroler Arduino Uno melalui sensor tegangan. Alat ini mampu mengisi daya kebutuhan elektronik saat mendaki gunung seperti handphone/smartphone dan lampu penerangan. Pengujian dilakukan dengan menvariasikan kondisi medan pegunungan pada keadaan diam, berjalan, dan jalan mendaki. Alat ini mampu menghasilkan tegangan maksimal sebesar 22,4 V dan arus maksimal 18,4 mA saat jalan mendaki. Hasil dari penelitian ini menunjukkan bahwa semakin besar tekanan yang diberikan oleh kaki dari pendaki gunung, maka semakin besar pula tegangan dan arus yang dihasilkan.

Abstract

The concept of electromagnetic induction is very important in understanding and developing modern electrical technology. Some factors cause students to often find it difficult to understand electromagnetic induction material in school is that this material involves abstract concepts such as magnetic flux, magnetic field changes, and emf. For some students, understanding these concepts may be difficult due to a lack of direct experience or concrete representations. Enrichment of physics material on electromagnetic induction has been implemented at SMA N 1 Gunung Talang. This service activity aims to improve students' understanding of the basic concepts of Electromagnetic Induction in Class XII. This service consists of three stages including: preparation, implementation and evaluation. The evaluation of this activity was carried out by comparing the pre-test results before enrichment and the post-test scores of students after being given enrichment material by the lecturer (service team). The results obtained show an increase in student knowledge towards understanding the concept of electromagnetic induction. This service activity can be an effort for school and university cooperation to support student success in understanding physics concepts that are considered complicated
