Abstract

This study evaluates the pedagogical effectiveness of integrating Problem-Based Learning (PBL) with structured student worksheets to enhance scientific reasoning skills. The primary objective is to address the global demand for sustainability education by focusing on renewable energy topics for junior high school students. The research employs a developmental model to design and evaluate a dual-learning approach through field trials and pre-experimental assessments. Findings indicate that the synergy of PBL and structured worksheets significantly improves students' capacity to analyze scientific data, construct evidence-based arguments, and verify complex assumptions. Students demonstrated a heightened ability to apply scientific knowledge to real-world energy challenges, making the learning process more relevant and engaging. The novelty of this research lies in its dual-approach framework, which systematically scaffolds reasoning processes while aligning with educational goals for sustainable development. This study concludes that while this integration provides a robust practical framework for science education, its success depends heavily on comprehensive teacher preparation in inquiry-based methodologies.

Abstract

The poor performance of second-grade science pupils at SD Negeri 4 Berbek prompted this research. The failure to employ creative forms of educational media that can pique students' interest and deepen their comprehension contributes to subpar learning outcomes. The primary goal of this research is to examine the efficacy of ebooks as a serialized visual medium for scientific education. Two cycles of classroom action research (PTK) were employed as the research approach. A total of 25 second-grade students from SD Negeri 4 Berbek served as research subjects. The background of this study highlights that conventional teaching media are often ineffective due to their inability to engage students actively and cater to diverse learning styles. Research indicates that traditional methods may lead to passive learning, resulting in lower retention and understanding of scientific concepts. Evidence suggests that second graders at SD Negeri 4 Berbek had average learning outcomes that were far lower than the national norm, highlighting the need for new strategies. Interviews, observations, and tests measuring learning outcomes were used to gather data. The findings demonstrated that students' scientific learning outcomes may be enhanced by the utilization of serialized graphic media based on ebooks. Students ' average scores rose from 63.2 (before implementation) to 75.4 (after), and 72% of them were able to finish the first cycle. The average score rose to 84.8 in cycle II, and 92% of the learning was retained. Students also showed increased engagement and excitement as they learned. The results of this study show that second graders at SD Negeri 4 Berbek can improve their academic learning outcomes by using ebooks as a serialized visual medium.

Abstract

This study aims to evaluate the dynamic performance of NaOH-activated hybrid adsorbent derived from jengkol peels and coconut shell for Cu(II) removal in a fixed-bed column. The performance indicators include the adsorption capacity, removal efficiency, and structural characterization. The hybrid adsorbent was characterized using Fourier Transform Infrared Spectroscopy (FTIR) to identify functional groups that play a role in the adsorption process and Scanning Electron Microscope (SEM). The FTIR characterization results showed that the hybrid adsorbent was rich in functional groups such as hydroxyl (-OH), aromatic stretching (C=C), and aliphatic (C-H) groups. Meanwhile, the SEM characterization showed that the surface structure of the adsorbent tended to be honeycomb-shaped with varying pores. The adsorption test was performed in a downflow fixed-bed column under continuous operation with a total operation time of 30 minutes. Under the tested conditions (influent concentration of 100 mg/L and flow rate of 25 mL/min), 95% removal was achieved at 30 min in the fixed-bed column system, corresponding to a dynamic adsorption capacity of 11.3 mg/g. Kinetic modelling indicated that the Thomas and Yoon – Nelson models provided a better fit than the Adam-Bohart model, indicating that adsorption was primarily controlled by surface kinetics rather than intraparticle diffusion. This biomass waste-based hybrid adsorbent has the potential to be an environmentally friendly alternative for treating liquid waste containing Cu ions.
