Abstract

In this study, activated carbon from cassava peel waste has been synthesized, with the aim of analyzing its effectiveness in reducing BOD and COD levels in laundry wastewater. Activated carbon was synthesized through a carbonization process at various temperatures (250°C, 300°C, 350°C) for 1.5 hours, then chemically activated using 2% KOH and physically activated with microwaves. Morphological characterization using SEM, and adsorption effectiveness was tested with contact time variations of 0 and 5 days for BOD, COD, pH, and temperature parameters. The results of SEM characterization showed that the carbonization temperature of 300°C produced optimal micro and mesoporous pore structures without structural damage. Treatment with activated carbon from 300°C carbonization (sample A2) showed the best performance, with a decrease in BOD from 450 mg/L to 200 mg/L and COD from 21.7 mg/L to 3.72 mg/L. The pH and temperature values after adsorption also meet environmental quality standards, namely neutral pH (7) and temperature 25.7°C. Activated carbon from cassava peel waste has been proven to be effective as an environmentally friendly adsorbent for laundry waste processing.

Abstract

This study aims to develop an interactive e-module based on Outcome-Based Education (OBE) in Solid State Physics courses to improve students’ scientific literacy and independent learning. The research employed the ADDIE development model (Analysis, Design, Development, Implementation, Evaluation). The subjects were 20 sixth-semester students of the Physics Education Program, Universitas Nurul Huda. Data were collected through needs assessment questionnaires, expert validation, scientific literacy tests, and independent learning questionnaires. Validation results showed that the e-module obtained an average score of 90% (material expert) and 89% (media expert), categorized as feasible. A limited trial indicated an increase in students’ scientific literacy from an average score of 58,2 (pre-test) to 78,9 (post-test) with a gain index of 0,42 (medium category). Independent learning improved from an average score of 3,1 to 3,8 on a 5-point Likert scale. The product has also been granted Intellectual Property Rights (HKI) certification. Therefore, the OBE-based interactive e-module is feasible to be used as an innovative learning medium to support students’ learning outcomes.

Abstract

This study is a research and development (R&D) project aimed at producing a multirepresentation-based electronic worksheet (E-LKPD) assisted by Liveworksheet on Newton's Law material that is both valid and practical for use in high school physics learning. The development model employed utilizes the initial three phases of ADDIE, namely Analysis, Design, and Development. The research findings demonstrate that the developed E-LKPD product falls within the category of highly valid and highly practical, with an Aiken's V validity index of 0.852, classified as excellent or highly valid, and a practicality level of 85.95%. The multirepresentation approach facilitates students' understanding of Newton's Law concepts through various forms of representation, including verbal, visual, mathematical, and diagrammatic representations. Furthermore, the interactive features embedded in Liveworksheet provide immediate feedback that supports students in learning independently and reflectively. Overall, this E-LKPD is valid and practical so that deemed suitable for use as an innovative learning medium and is expected to enhance students' conceptual understanding and higher-order thinking skills.
