Abstract

Abstract. Coal Mining Activities at PT. Arta Mulia Tata Pratama is implementing an open pit system. Coal getting activity is one of the mining activities at PT. ATP. Before doing the activities, coal getting coal volume must be known first. It is for knowing how much the actual volume of coal is measured on the floor and roof on material that will be mined. The actual volume is 186.528.0 tons. while the planned plant of the company is 189.525.0 tons. This indicates that no fulfillment  2,997 tons of coal production targets in the month of January 2018.In coal extraction activities can be happend loose (lost / wasted) of coal material. cleaning on the coal floor, coal damage, and slope mismatch. These factors must be assessed to see the contributions of the waste of coal material and analyzed problems. It is aimed to get accurate data and increase the recovery. This method uses the fishbone method that aims to analyze the problems in the causal factors of coal loose. it is found that the loose contribution of coal loose on the clean floor coal is 890,786tons, loose contribution to coal damage is 89.86 tons, and coal loose contribution to slope is 1.824,615tons.Keywords: coal loose, cleaning floor, coal damage , slopes, fishbone

Abstract

This study is motivated by the demands of 21st-century learning which requires the integration of digital technology to improve the quality of the teaching and learning process in elementary schools. Science and Social Studies (IPAS) learning in the Merdeka Curriculum is expected to encourage students to think critically, solve problems, and actively participate in learning activities. However, based on observations and interviews conducted in several elementary schools in Region II of Lubuk Kilangan District, Padang City, it was found that learning activities were still dominated by conventional teaching methods and printed worksheets, resulting in limited student engagement. In addition, the use of digital technology in learning has not been systematically integrated with innovative learning models such as Problem Based Learning (PBL). Therefore, this study aims to develop an electronic student worksheet (E-LKPD) assisted by the Wordwall media using the Problem Based Learning model in IPAS learning for fourth-grade elementary school students. The developed E-LKPD is designed to facilitate students in identifying problems, conducting investigations, collaborating in discussions, and presenting solutions systematically through interactive digital activities. Wordwall is utilized to provide educational games and interactive learning activities that can enhance students’ motivation and engagement in the learning process. By integrating the PBL model with Wordwall media, the developed E-LKPD is expected to become an innovative learning medium that supports more effective IPAS learning, improves students’ critical thinking skills, and encourages active participation in classroom activities. The results of this development are expected to serve as an alternative digital learning medium that is practical, engaging, and relevant to the needs of learning in the digital era.
