PENGARUH PROBLEM BASED LEARNING (PBL) TERHADAP KEMAMPUAN BERPIKIR KRITIS SISWA SMK PADA MATA PELAJARAN INSTALASI PENERANGAN LISTRIK (IPL) 

THE EFFECT OF PROBLEM BASED LEARNING (PBL) ON CRITICAL THINKING ABILITY OF VOCATIONAL HIGH SCHOOL STUDENTS IN ELECTRIC LIGHTNING INSTALLATION SUBJECTS (IPL)

Model pembelajaran Problem Based Learning (PBL) adalah model pembelajaran yang fokus terhadap operasi penyelesaian masalah sesusai situasi nyata, agar siswa mampu berpikir kritis, analisis, dan mandiri. Berpikir kritis adalah kemampuan untuk menyelesaikan masalah, berdasarkan pertimbangan dan analisis sehingga mendapatkan keputusan yang terbaik. Penelitian bertujuan untuk mengetahui pengaruh model PBL berkenaan kemampuan berpikir kritis siswa dan langkah-langkah dalam penerapannya, Serta untuk mengetahui potensi keberhasilan model PBL apabila diterapkan pada siswa SMK mata pelajaran Instalasi Penerangan Listrik (IPL) dalam meningkatkan kemampuan berpikir kritis. Penelitian ini menggunakan metode studi literatur, dari beberapa sumber referensi seperti jurnal, buku tesk, artikel, dan penelitian yang relevan serta berkaitan dengan model PBL. Hasil dari studi literatur, menunjukan siswa yang melaksanakan kegiatan belajar dengan PBL mengalami peningkatan kemampuan untuk berpikir kritis. Langkah-langkah dalam penerapan model PBL adalah sebagai berikut: (1) mengarahkan siswa kepada masalah; (2) mengintegrasikan siswa untuk belajar; (3) membatu proses investigasi individu dan kelompok; (4) mengembangkan dan menampilkan hasil karya (eksperimen); (5) menganalisis dan mengevaluasi metode penyelesaian masalah. Berdasarkan beberapa penenlitian yang telah di analisis PBL memiliki potensi besar untuk mampu meningkatkan keterampilan beripikir kritis siswa SMK pada mata pelajaran IPL.

The Problem Based Learning (PBL) model is a learning model that focuses on problem solving operations which is appropriate with the real situation, so students are able to think critically, analyze, and be independent. Critical thinking is an ability to solve problems, based on consideration and analysis so it can gets the best decision. This research is aimed to know the effect of PBL learning models with regard to students' critical thinking skills and their application steps, and is aimed to understand the potential improvement of PBL models that are applied to vocational students who take Electrical Lightning Installation (IPL) courses in improving critical thinking skills. This research uses the literature study method, from several reference sources such as journals, textbooks, articles, and relevant research related to the PBL model. The results of the literature study, show that students who conduct learning activities with PBL  improve the ability to think critically. The steps in applying the PBL model are: (1) direct students into the problems; (2) Integrating students to learn; (3) assisting individual and group investigation process; (4) developing and displaying the creation (experiment); (5) analyze and evaluate problem solving methods. Based on some research tha have PBL analysis has great potential to improve students’ thinking skills on IPL Subjects.
