Abstract

The growing demand for energy and the depletion of fossil fuel resources have increased the urgency of finding renewable and sustainable energy sources. Biogas produced from cow manure through anaerobic digestion offers a promising option because it can turn agricultural waste into usable energy. However, raw biogas contains a high proportion of carbon dioxide (CO₂), which reduces its calorific value and must be removed to improve its quality. This research evaluates the effectiveness of four amine based absorbents, namely monoethanolamine (MEA), diethanolamine (DEA), triethanolamine (TEA) and methyldiethanolamine (MDEA), for purifying biogas in a packed absorption column. The column was filled with Pall rings to enhance gas and liquid contact and operated at room temperature (around 25 °C) and atmospheric pressure with a constant flow rate of biogas. Each amine solution was prepared at concentrations between 10% and 50%. The methane and carbon dioxide contents were measured before and after the purification process to assess removal efficiency. The findings indicate that MEA achieved the highest level of carbon dioxide removal, raising methane concentration from 58.3% to 78.2% at a 50% solution. DEA also showed good performance, although not as high as MEA, while TEA and MDEA produced lower removal efficiencies. These results demonstrate that amine based absorption can significantly improve the quality of biogas. In summary, MEA proved to be the most effective absorbent under the conditions tested, offering a practical and cost effective approach for small to medium scale biogas purification systems. These findings provide useful information for improving chemical absorption techniques to support wider use of renewable energy.

Abstract

Teachers in rural Islamic boarding schools (pesantren) often have limited access to digital training and few opportunities to develop innovative instructional media for Arabic language instruction. This study investigates how mobile-based training can empower Arabic language teachers to create animated learning videos and examines the types of mentoring that facilitate this process. Using a qualitative Participatory Action Research (PAR) design, the study engaged 16 teachers from three rural pesantren in iterative cycles of training, hands-on practice, reflection, and guided mentoring. Data were collected through in-depth interviews, observations, documentation of teacher-produced videos, and continuous digital communication. The findings reveal a six-phase empowerment process: initial digital literacy gaps, emerging awareness of the pedagogical potential of mobile technology, step-by-step skill acquisition through experiential practice, negotiation of technical and contextual challenges, internalization of digital competence accompanied by increased self-efficacy, and early instructional implementation of animated videos. Mentoring, characterized by personalized guidance, responsive troubleshooting, modeling of complex procedures, and sustained online support, was essential in maintaining engagement and overcoming technological barriers. Teachers reported greater confidence, stronger professional agency, and improved capacity to design context-appropriate digital media. The study accomplishes that mobile-based training supported by intensive mentoring can effectively empower teachers in resource-limited Islamic educational settings. The proposed six-phase empowerment model offers a scalable and contextually adaptable framework for teacher development initiatives in rural and underserved environments

Abstract

Green Open Space (GOS) is a critical urban element, but the legally mandated minimum 30% area is often unmet. This study aims to analyze the changes in the GOS area from 2002, 2013, and 2024 and the factors influencing it. GOS area change was analyzed using the delineation method on high-resolution satellite imagery from Google Earth Pro, and the results showed that the area of GOS in Surakarta City in 2002 was 360.95 ha, in 2013 was 341.18 ha, and in 2024 was 328.76 ha. Logistic regression analysis was applied to model the influence of explanatory variables, resulting in findings that distance to the road, distance to settlements, distance to transportation facilities, and population density are significant variables influencing GOS decline. Although these variables only explained 9.1% of the change, this suggests that there could be other external factors affecting GOS that have not been analyzed in this study. The local government needs to strengthen policies, tighten building permit supervision, and ensure consistency with Regional Spatial Planning to optimize existing GOS and develop new GOS in potential locations to address the deficit of approximately 1,072.84 ha.

Abstract

An animated video learning medium utilizing the Powtoon platform was developed to strengthen literacy proficiency in Indonesian language education at the vocational high school level. Employing a Research and Development (R&D) framework with the ADDIE model, the study systematically proceeded through stages of analysis, design, development, implementation, and evaluation. A total of 70 tenth-grade students from SMK Negeri 2 Batam participated as purposively selected subjects. Expert validation and user assessments confirmed that the media met high-quality standards in content accuracy, visual appeal, and linguistic clarity. Students and teachers reported the platform to be intuitive and well-suited to the learning preferences of vocational learners. Quantitative analysis revealed a substantial increase in student achievement, with an N-Gain score of 0.53, placing it within the moderate-to-high improvement range. These results affirm that Powtoon-based animated learning not only enhances engagement but also significantly boosts literacy outcomes. The media presents a powerful pedagogical tool for modern classrooms, particularly in overcoming passive and text-heavy instructional barriers. Future research should explore its application to other language domains and broader educational contexts to assess its generalizability and long-term impact

Abstract

This study aims to determine the effectiveness of the Problem-Based Learning (PBL) model assisted by a treasure hunt game on conceptual understanding and interest in learning mathematics in Grade II elementary school students. This study used a quasi-experimental method with a non-equivalent control group design involving 21 students in the experimental class and 19 students in the control class. Data were collected using a pretest–posttest instrument for conceptual understanding and a questionnaire for learning interest. Data analysis included normality and homogeneity tests, followed by dependent and independent sample t-tests, and N-gain score tests using SPSS version 16.00. The results showed that the implementation of PBL assisted by a treasure hunt game had a positive and significant effect on conceptual understanding and interest in learning mathematics in Grade II elementary school students. Students in the experimental class obtained higher posttest scores and N-gain scores compared to students in the control class who received conventional learning. Thus, PBL integrated with treasure hunt game activities can be considered an effective learning approach to improve conceptual understanding and interest in learning mathematics in early-grade elementary students.

Abstract

This study aimed to develop a valid and reliable electronic portfolio assessment instrument to support learning and potentially improve students’ habits of mind on acid-base material. Using a Research and Development (R&D) approach with the 4D model (Define, Design, Develop, and Disseminate), the instrument was tested on 30 eleventh-grade students in a public high school in Cimahi City. The habits of mind focused on three indicators: self-regulation, critical thinking, and creative thinking. The instrument included various tasks relevant to the acid-base topic. Validation results showed strong content validity (CVR = 1.00) and reliability (Cronbach’s Alpha values ranging from 0.70 to 1.00). A limited trial suggested potential improvements in students’ habits of mind, with observed levels of self-regulation categorized as medium to high, and critical and creative thinking ranging from low to high. However, these findings are preliminary, and further research using a more robust experimental design is needed to confirm the instrument’s effectiveness

Abstract

Misconceptions in science learning remain a major barrier to students’ conceptual understanding, while traditional assessments often fail to detect them effectively. This study aimed to develop PhyTestApp, an app-based diagnostic tool that integrates the Partial Credit Model (PCM) under Item Response Theory (IRT) to uncover student misconceptions in science. A research and development design was employed, involving expert validation, limited trials, and psychometric testing. The two-tier items were designed to capture both factual knowledge and reasoning. Findings indicated that the instrument met psychometric requirements, with items demonstrating good fit and functioning across different levels of student understanding. Usability testing also showed positive responses from students and teachers regarding clarity, content relevance, and technical operation. Overall, PhyTestApp provides a reliable and practical diagnostic tool that facilitates immediate feedback and supports more targeted science instruction. These results highlight the potential of combining psychometric modeling with mobile technology to improve the quality of science education and more effectively address misconceptions in line with 21st-century learning goals.

Abstract

Construction remains a highly hazardous industry, and strengthening Occupational Safety and Health (OSH) is urgent to reduce injuries and occupational illnesses while sustaining productivity. However, in four-storey construction, OSH is often treated as compliance, and evidence is limited on its measurable contribution to workforce effectiveness and on which OSH factors should be prioritized. This study evaluated OSH implementation in the Ishk Tolaram Eye Clinic (four-storey) project in Batu City, Indonesia, using observations and questionnaires from supervisors and artisans/forepersons, analyzed with SEM-PLS. The structural model shows a strong, positive, and significant effect of OSH implementation on workforce effectiveness (path coefficient = 0.76; t = 13.46; p = 0.00). OSH implementation explains 58.0% of the variance in workforce effectiveness (R² = 0.58); occupational health is the most dominant OSH dimension (loading = 0.72), and adequate sanitation conditions (X2.4) are the key leverage point (loading = 0.80). This research contributes a multidimensional, evidence-based evaluation framework that converts OSH from a checklist into prioritized drivers linked to workforce outcomes. In practice, contractors should prioritize occupational health controls, especially sanitation, alongside training and PPE discipline, to improve safety performance and reliable productivity across comparable four-storey projects in Indonesia.

Abstract

Strategic implementation of blockchain in the fisheries industry can improve logistics efficiency and consumer confidence in ethically and sustainably sourced fishery products, which are important pillars for national and global food security. This strategic model essentially integrates blockchain technology into every stage of the fisheries supply chain to address issues such as lack of transparency, fraud, and unsustainable fishing. Its primary impact is the provision of reliable data on product origin, condition, and compliance with sustainability standards, thus directly helping the fishing industry contribute to the SDG targets. The performance of the fisheries industry supply chain is crucial to the success of food security and the achievement of the Sustainable Development Goals (SDGs). Key challenges in this sector include low transparency, distribution delays, IUU fishing practices, and unequal access to information among actors. Blockchain technology is considered capable of addressing these issues through a secure, transparent, and decentralized digital recording system. This study aims to design an optimal strategy for blockchain implementation in the fisheries supply chain based on an Operational Research (OR) approach, specifically using the goal programming method. Modeling results indicate that investment in a logistics traceability system and digitalization training for fishermen provide the greatest contribution to improving efficiency and food security. This study recommends cross-sector integration between the government, business actors, and blockchain technology providers.

Abstract

This study aims to analyze the critical thinking skills of junior high school students in environmental pollution materials based on gender differences. The research used a descriptive-comparative design with 60 Grade VII students at MTs Raudhatul Azhar, East Lombok, selected purposively. Data was collected using an essay test consisting of four indicators of critical thinking: elementary clarification, advanced clarification, information gathering, and inference. Descriptive results showed that female students had higher average scores (M = 77.8; SD = 5.4) than male students (M = 68.9; SD = 6.1). Independent t-test results confirmed significant differences in all indicators (p < 0.05), indicating that female students demonstrated higher levels of critical thinking skills. The results highlight the importance of developing learning strategies that are sensitive to gender characteristics to support the equitable development of students’ critical thinking skills.
