Abstract

Coal mining will form acid mine drainage in former open pit mines. If acid mine water enters community waters, it will cause disturbance to biota and decrease water quality. Sawahlunto is one of the cities in Indonesia that has a coal mining area located near a settlement. With the acid mine drainage, if it rains, the water will flow into the river where the water is used by the community. Part of the coal is used as fuel for the Sijantang Sawahlunto PLTU. The fuel also produces waste in the form of combustion ash known as fly ash and bottom ash (FABA). This study uses FABA to neutralize acid mine water to meet the community's irrigation water needs. This research will determine the appropriate mass of FABA in neutralizing acid mine drainage. Acid mine water comes from the former mining pit of PT. High Guguak Coal with a pH of 2.88. Then the acid sample is brought to the laboratory to be mixed with FABA and lime. 4.98 grams of FABA with 0.02 lime can neutralize 200 mL of acid mine drainage and change the pH from 2.88 to 7.91. FABA can be included in the settling pond to neutralize acidic water before it is released into community waters.

Abstract

A learning model is a form of process or way of presenting learning activities from beginning to end. This learning model serves as a means of communication in the classroom. This study aims to determine whether there are differences in the evaluation of pure learning outcomes by applying the Project-Based Learning (PjBL) and Problem Based Learning (PBL) learning models with the Pretest score as a controller. The number of subjects in this study was 42 mining engineering students in applied physics courses using the purposive sampling method. Data was collected by asking questions before being given treatment and after being given treatment. The data analysis technique used is the analysis of covariance (ANCOVA) in evaluating student learning outcomes. The findings indicate that there are significant differences in learning outcomes between the Project-Based Learning (PjBL) learning model and the Problem Based Learning (PBL) learning model by controlling the Pretest score. The significance of the PjBL learning model gives different and higher results compared to the PBL learning model. The application of the Project-Based Learning learning model provides many more meaningful and meaningful learning experiences for students in improving the evaluation of learning outcomes.

Abstract

This study aims to analyze the effectiveness of the effect of the Project-Based Learning (PjBL) learning model on student learning outcomes. There were 26 articles analyzed in this study. The articles collected have been published in national journals, international conferences, and international journals for the last 3 years from 2018 to 2021 related to Project-Based Learning (PjBL) and learning outcomes. This research uses a meta-analysis method by calculating the effect size value in each article. Four formulas are used to calculate the effect size value for each article. This research is meta-analysis research based on the form of learning outcomes with the Project-Based Learning (PjBL) model, Year, Type of Integration, Effect Size Value, and Type of Publication. The meta-analysis results show that the average effect size of PjBL on student learning outcomes is high and significant. The Project-Based Learning (PjBL) model is mostly integrated with the Conventional Learning (CvL) model. The order of most publications starts from national journals, international journals, and international conferences, all three of which have an average effect size value in the high category, and there is no publication bias. Based on data analysis, Project-Based Learning (PjBL) can increase students' creativity in learning. Besides, it helps students to be able to think more critically in solving problems. This model can also improve students' skills to help them compete in the 21st century and the era of society 5.0.
