The development of renewable energy, particularly Solar Power Plants (PV), requires a reliable, real-time, and easily accessible electrical energy monitoring system to ensure optimal system performance. This study aims to design and implement an Internet of Things (IoT)-based electrical energy monitoring system for PV using the NodeMCU ESP32 microcontroller, the PZEM-004T sensor for measuring electrical parameters, and the Node-RED platform as the data visualization interface. The developed system is designed to monitor voltage, current, power, energy, frequency, and power loss in real time, and then display the data in the form of numerical values, graphs, and indicators on a dashboard accessible through a local network. The research method includes hardware design, software development (sensor reading, data processing, and communication), integration with Node-RED, and system testing on a small-scale PV installation. The test results show that the system is capable of monitoring electrical parameters in a stable and responsive manner. Variations in sunlight intensity were found to affect the current and power produced by the solar panels, whereas the inverter output voltage tended to remain within normal operating ranges. The Node-RED dashboard display was considered informative and helpful for users in monitoring and analyzing PV performance. Based on these results, it can be concluded that the IoT-based electrical energy monitoring system designed in this study functions well and is feasible for application in residential or educational-scale PV installations. The system still has the potential for further development through cloud service integration, the addition of environmental sensors, and enhancements to data analysis features and user interface design.

The current education system is facing a crucial dilemma: the intensifying focus on cognitive achievement amidst the specific challenges faced by Generation Z. Junior high school students aged 12–15, who are digital natives, are at risk of reduced social interaction and mental health issues due to high screen time. Addressing this urgency, this study aims to describe the strategic role of dance arts education in shaping character and creativity, and to identify implementation solutions at SMP Negeri 1 Wonogiri. This descriptive qualitative study utilized 8 students active in dance as primary subjects, with data collected through observation, interviews, and documentation. The findings indicate that dance arts, through an embodied learning approach based on physical movement, is highly effective in cultivating character. Values such as discipline, which is transferred from the punctuality required in practice to general school life , collective responsibility , and self-confidence that overcomes social awkwardness, grew significantly. Furthermore, dance reinforces authentic cooperation and cultural appreciation. In terms of creativity, the activity encourages movement exploration, improvisation, and creative problem-solving. Psychologically, dance practice functions as a positive coping mechanism that effectively lowers adolescent stress levels. Although constraints exist, such as limited instructional time (80 minutes per week) , adaptive solutions like strengthening extracurricular activities and the peer tutoring system are being implemented. This research concludes that dance arts education is an essential and strategic medium for developing holistic competencies, including the 4Cs (Critical Thinking, Creativity, Collaboration, and Communication) and the Profil Pelajar Pancasila.

The aim of this research is to explain the impact of implementing integrated STEAM learning based on Local Wisdom in improving the 4 Cs in the 21st Century. The research method used is a case study in an elementary school, with data collection through classroom observations, interviews with teachers and students, as well as analysis of the results. learning before and after implementing STEAM learning. The data in this study were analyzed using qualitative descriptive analysis. The research results show that integrated STEAM learning based on local wisdom helps elementary school students achieve 21st century skills such as critical thinking, creativity, collaboration and communication, with an average increase of over 3,500 in each skill category. Furthermore, contextual learning by integrating local wisdom in learning makes learning more meaningful. The implications of this research provide an important contribution to the development of meaningful learning management in elementary schools to equip students with the skills needed in the future.

Taman Makam Abu Ambarawa is a cemetery managed by the Gotong Royong Social Foundation, has been using infographics in promotional media in the form of brochures, catalogs and business cards since 2017. This study was conducted to determine the effectiveness of using infographics in promotional media. The EPIC model is used as a method to determine the effectiveness of infographics in the promotional media that have been used, using the indicators of Empathy, Persuasion, Impact and Communication. Respondents in this study were people who had used the services of Taman Makam Abu Ambarawa. The results of this study indicate that the use of infographics in promotional media is very effective, with an EPIC index score of 3.38 indicating that the decision scale is very effective. While the tabulation of the EPIC and EPIC Rate dimensions indicated that the four dimensions of the EPIC model (empathy, persuasion, impact and communication) had a value greater than the minimum value of Very Effective of 3.25. This research can be used by stakeholder are related to cooperatives and UMKM, regarding the perspective of the use of infographics in promotional media that has proven to be effective, through the use of infographics to display products or services in promotional media for the cooperative development and UMKM.
