Solusi Pencemaran Air Menggunakan Teknik Fitoremediasi Sebagai Bentuk Penerapan Model Project Based Learning di Masa Pandemi Covid-19

Abstract

This study aims to determine the effectiveness of the implementation of the Project Based Learning model during the Covid-19 pandemic. The concept of project-based learning is applied in an effort to ignite student activity and critical thinking skills in learning. The research method used is a quantitative method with an experimental type. The research was conducted at STKIP PGRI Nganjuk with a sample of 49 students. Data collection techniques in the form of test instruments, questionnaires, and observations. Student activities are carried out in the form of a practicum project with the theme "Solution of Water Pollution Through Phytoremediation Techniques". The research results obtained are an increase in students' critical thinking skills. The data showed an increase if before treatment or pretest 0.24 (low criteria) to 0.41 (medium criteria). The results of the practicum data also show that phytoremediation using water hyacinth phytoremediator has proven to be effective in suppressing water pollution.
