Abstract

High-quality water resources are important parameters for the sustainability of human civilization, the health of ecosystems, and the advancement of vital sectors. High-quality water is also needed for shrimp cultivation ponds. However, water-quality monitoring in the estuary is limited. In line with this, this study focuses on the design and implementation of an IoT-based TDS and temperature measurement system for estuarine water, aiming to develop an efficient, accurate, and automated prototype to support the fisheries sector in West Lombok regency. This study used a microcontroller, temperature and TDS (total dissolved solids) sensors, a wireless router, and a display. These elements were developed as a water-quality-level monitoring system based on TDS and temperature. The system was calibrated using a standard comparator before being examined under real conditions. The calibration procedure was conducted inside a controlled chamber at a water temperature of 25°C for 60 minutes, with a steady flow rate. All procedures were repeated three times and tested using a Student’s t-test. The IoT platform was tested using RSSI values with a 2s update interval. The calibration data were interpreted as a linear function between the standard and the developed system. The resulting design shows that the developed system can be installed at a shrimp cultivation pond with good performance. The designed system has a linearity of more than 90%. The system has a reliable accuracy level over 30 consecutive measurement days, resulting in the percentages of 85% to 93% (average = 91%). It can be concluded that IoT data communication via a wireless internet router performs well, with RSSI> -50 dBm for both sending and receiving. The IoT platform using ThingSpeak shows good performance (good stability), with a 2-second interval between data updates.

Abstract

Air emissions are a critical issue that can directly impact public health. The larger the emission source, the greater the potential for exposure to the resulting emissions. This problem is also faced by residents (partners) in the Pesona Banyu Asri neighborhood, Banyumulek, West Lombok Regency. Air pollution generated from many directions (four main sources) in the partner area (waste management at the Kebon Kongok landfill, plastic waste processing at BRIDA, waste processing into biofuel, and the pottery production process in the Banyumulek tourist village) is quite high, but the process of quantifying and characterizing emissions has not been implemented/studied in detail. Therefore, the purpose of this community service is to provide alternative solutions that can improve community preparedness regarding air emission disaster mitigation. The implementation method of community service activities is focused on PAR (participatory action research) techniques to improve social aspects of the community. The priority is to identify problems and provide alternative solutions related to the impact of air emission exposure due to emission source activities around the partner area. The IoT (Internet of Things)-based air management system developed by the community service team was previously implemented directly in the community, through stages of observation, socialization, training, installation, and final assessment. The results of the community service process can be seen from the questionnaire data quantification process, where there was a significant increase between before and after the community service activity. The readiness of the partner community increased by 62% regarding the ability to understand air mitigation, both in terms of understanding the types of air emissions, air purification systems, and the operation of the IoT-based air management system that is beneficial for partners.

Abstract

Critical thinking skills are essential competencies in the 21st century that students must possess. The Project-Based Learning (PjBL) model is believed to be an effective pedagogical approach to develop these skills. This study aims to describe the trends and effectiveness of the PjBL model in enhancing students' critical thinking skills based on a literature review. This study employs a descriptive literature review approach by analyzing relevant scientific publications from the last ten years. A bibliometric analysis using VOSviewer was also conducted to map research topic trends. The analysis results indicate that research on PjBL and critical thinking has significantly increased. The PjBL model, whether implemented purely or integrated with other approaches such as STEM, is consistently proven effective in enhancing critical thinking skills across various educational levels and subjects. This effectiveness is driven by the PjBL syntax that emphasizes real project-based learning, collaboration, and problem-solving, which directly trains students' metacognitive and analytical aspects.

Abstract

The rapid development of digital technology has transformed the way individuals access, process, and utilize information in various aspects of life, including education. In the context of 21st-century learning, students are required to possess digital literacy and critical thinking skills to evaluate information effectively in an increasingly complex digital environment. This study aims to analyze the relationship between digital literacy and critical thinking as essential skills for 21st-century learners. This research employed a Systematic Literature Review (SLR) method by examining 30 scholarly articles published between 2016 and 2025. The data were collected from several academic databases, including Google Scholar, DOAJ, ERIC, and ScienceDirect, using the keywords critical thinking, digital literacy, digital learning, and 21st-century skills. The article selection process followed the PRISMA approach, while thematic analysis was used to identify research patterns and key themes. The results indicate that digital literacy plays a significant role in enabling students to access, understand, and critically evaluate digital information. Furthermore, the integration of digital technology in learning environments can enhance students’ critical thinking skills through activities such as information analysis, online discussions, and collaborative learning. The findings also reveal that digital literacy and critical thinking are closely interconnected and mutually reinforcing competencies that support effective learning in the 21st century. Therefore, integrating these competencies into educational curricula is essential to prepare students for the challenges of the digital era.

Abstract

The diversity of students' abilities, interests, and learning styles presents a primary challenge in Science education. Traditional, one-size-fits-all approaches often fail to meet the needs of all learners optimally. Differentiation and personalized learning offer flexible, student-centered strategies tailored to individual needs to support the effective achievement of science competencies. This article examines the concepts of differentiation and personalized learning, their implementation strategies in science education, and literature findings regarding the effectiveness of both approaches on student motivation, conceptual understanding, and 21st-century skills. The study indicates that differentiating content, process, product, and the learning environment—coupled with interest-based personalized learning strategies—can enhance engagement, motivation, conceptual mastery, and critical thinking skills. These approaches are recommended as integral components of modern, inclusive science education aligned with the principles of the Kurikulum Merdeka (Emancipated Curriculum).

Abstract

Modern physics education emphasizes the development of higher-order thinking skills, including critical thinking and problem-solving, alongside conceptual understanding. Static electricity, being an abstract topic, often presents difficulties and gives rise to student misconceptions. PhET Interactive Simulations serve as a digital learning medium that enables the interactive visualization of electrical phenomena, thereby allowing students to explore concepts and conduct virtual experiments. This study conducted a systematic literature review to examine the integration of PhET in static electricity instruction and its impact on developing students' critical thinking and problem-solving skills. A literature search was performed across Google Scholar, ERIC, and ScienceDirect for publications spanning 2015–2025, resulting in 21 selected articles for qualitative analysis. The findings indicate that the utilization of PhET enhances conceptual understanding of static electricity, critical thinking abilities, problem-solving skills, and student engagement in learning. The interactive visualizations within PhET correlate with improvements in the critical thinking dimensions of analysis, evaluation, and inference, as well as the problem-solving stages of understanding the problem, devising strategies, and evaluating solutions. These findings confirm that PhET Interactive Simulations can serve as an effective alternative learning medium to support the development of higher-order thinking skills in abstract physics topics.
