Abstract

Reverse Osmosis (RO) drinking water management can be the best solution to overcome the clean water crisis in Pulau Pinang. RO is a process that allows water to pass through a semi-permeable membrane and separates most of the dissolved salts, organic matter, bacteria, and other substances from the water to produce clean water. The use of the RO method in drinking water management is one of the best alternatives to overcome the clean water crisis, especially in the Pinang Island area with surface water sources that are not dominated by freshwater can ensure the availability of sustainable clean water. However, RO-based drinking water management is water demineralization, so further management is needed such as remineralization to meet mineral standards in drinking water.

Abstract

This research highlights the potential of anionic polyacrylamide as a main treatment agent for liquid waste from educational laboratories, particularly in the removal of copper ions. This study using experiment with varies the concentration of anionic polyacrylamide with 3, 5, and 7% weight per weight. The initial concentration of copper in liquid waste was very high ranging between 600 mg/L. The findings indicate that the application of anionic polyacrylamide in wastewater treatment significantly reduces the concentration of copper ions, especially in wastewater from educational laboratories. Specifically, anionic polyacrylamide, at a concentration of 3% w/w, effectively removed almost all copper ions from the wastewater found in analytical chemistry laboratory and also achieved the quality standard of treated wastewater for copper parameter. The pH of the treated wastewater is critical in determining the overall effectiveness of the treatment, with a higher pH resulting in more effective coagulation of copper ions. The effectiveness of the treatment is influenced by the pH of the wastewater and the concentration of the polyacrylamide used. Further studies are needed on other types of heavy metals that can be coagulated using this method in order to gain a more comprehensive understanding.

Abstract

This study developed innovative approaches to chemistry education for first-year students at the State University of Padang in the era of Industry 4.0. The research utilized the Plomp development model to formulate a method based on the Flipped Classroom paradigm with a Guided Inquiry Syntax. The resulting content was validated by five Chemistry lecturers at UNP, indicating its innovative and pertinent material depth. The content's practicality achieved a value of 90%, suggesting its ease of application and relevance for students. The systematic presentation enhances students' understanding of the Periodic System. This research offers valid and practical solutions to challenges in chemistry education, using creative content as an innovative strategy to provide a teaching tool that enhances students' understanding of complex concepts. The study's practicality stage demonstrates that the developed content is easy to apply and relevant for students, making it a valuable addition to chemistry education

Abstract

Education plays a vital role in cultivating qualified future generations, with active student participation serving as an indicator of effective learning processes. Preliminary observations at SMP Negeri 32 Padang revealed low engagement levels in science classes, prompting the need for interventions to boost students' involvement. The primary objective of this classroom action research was to enhance student engagement in science learning activities through implementing the Discovery Learning model and Teaching at the Right Level approach in a Grade 8 classroom at SMP Negeri 32 Padang. The study was conducted over three cycles, each consisting of planning, acting, observing, and reflecting phases. Data on student engagement in science learning activities was collected through observations using a rubric. The initial data in Cycle I revealed low engagement at 36.72%. After implementing interventions integrating Discovery Learning activities and personalized scaffolding based on students' ability levels in Cycles II and III, student engagement progressively increased to 45.76% and 62.28% respectively. Surveys and interviews indicated students found the learner-centered, inquiry-based activities more enjoyable and effective for understanding compared to traditional instruction. The findings demonstrate the potential of combining Discovery Learning and Teaching at the Right Level methods to significantly improve learning participation by stimulating intrinsic motivation through autonomous exploration while providing individualized support. The research offers practical strategies for enhancing science education engagement and contributes to the Kurikulum Merdeka goals of fostering participatory, flexible learning environments tailored to students' unique needs
