Abstract

This study aims to determine the effect of the PjBL (Project Based Learning) learning model on high school physics learning. The problem that often arises in the world of education is the weak ability of students to use their thinking skills to solve problems. Given that each student has a different learning style, PjBL (Project Based Learning) provides opportunities for students to explore content (material) using various means that are meaningful to themselves. The research method used is the research method and development (research and development / R&D) is a research method used to research so as to produce new products and then test the effectiveness of these products. The results of student learning using PjBL influence several things, such as creative thinking skills, elaboration, and even students can learn on their own without the help of others. Data collection in this study was carried out by observing and reviewing several journals through Google Scholar

Abstract

The slope stability angle of the surface landslide stability depends on the friction coefficient between the rock particles in the area. Measurement of slope stability is very useful for the safety of miners in mining areas. Measurement of slope stability is based on the friction coefficient. Measurements are made with a friction coefficient measuring instrument that has been designed and tested. Rock samples were taken at 3 rock mines around Mount Pengsong in West Lombok Regency. The measurement of the friction coefficient was carried out at the Physics Laboratory of the University of Mataram. The measurement results of the friction coefficient are then converted into slope stability angles. The results show that the slope stability angle in the mountains around the rock quarry around Mount Pengsong has a maximum value 5,71 degree of dry sample and 81,0 degree of moisture sample.
