This study aims to analyze the influence of economic factors on the Gross Regional Domestic Product (GRDP) in North Sumatra Province. The main issue raised is the need for an appropriate model to understand the relationship between economic variables and GRDP. This study uses panel data from 33 districts/cities during the period 2019–2023 obtained from official sources. Through Chow, Hausman, and Lagrange Multiplier tests, the Fixed Effect model was selected. The results indicate that population size, number of poor people, and Human Development Index (HDI) significantly influence RDP

Design and Development of an Automation Device for Free-Fall Motion Experiments Based on a Web-Remote Laboratory

Design and Development of an Automation Device for Free-Fall Motion Experiments Based on a Web-Remote Laboratory. This study aims to develop an automated free-fall experiment device integrated with a web-remote laboratory system. The web-remote laboratory is a real laboratory that can be controlled and displays results remotely through an internet connection. The research follows the Design and Development Research (DDR) methodology, which encompasses several stages: problem identification, objective formulation, system design and development, system testing, evaluation, and refinement. A domain hosting service was employed to deploy the web server, providing greater flexibility and ease in developing control interfaces compared to applications such as Blynk and ThingSpeak. The design and development process addressed both hardware-mechatronic and software components. The software was implemented on the microcontroller and the webserver to enable seamless integration. Testing was conducted in two phases, which informed product evaluation and subsequent refinements. The resulting device supports automation, features fully functional mechatronic systems, ensures optimized sensor sensitivity, facilitates user-friendly control via a web browser, and provides accurate calculations of gravitational acceleration during free-fall experiments. Despite its strengths, the ESP8266 microcontroller was suboptimal for applications requiring high sensitivity. Additionally, the web interface lacked multi-user support. These limitations present opportunities for further development and optimization of the device. Overall, the findings of this study provide a practical and innovative solution to enhance student engagement in laboratory activities, particularly in educational settings with limited access to physical laboratory equipment

A Comparative Analysis of the Intended Mathematics Curriculum of Cambodia and Singapore: Focus on Geometry

Cambodian students’ achievement is low in geometry problem-solving ability. This study aims to compare the intended mathematics curriculum of Cambodia and Singapore, with a specific focus on geometry. Four recently revised Cambodian mathematics syllabi, published in 2018 and two Singaporean mathematics syllabi, published in 2020, have been collected and analyzed following the General Topic Trace Mapping procedure. This analysis reveals significant differences between Cambodian and Singaporean mathematics curricula in design, structure and coherence, followed by domain, sub-domain, contents, sub-contents and learning outcomes within and across the grade. It also highlighted that the Cambodian mathematics curriculum on geometry lacks coherence in content, sub-content, and learning outcomes, potentially lowering student achievement. Enhancing curriculum coherence could significantly improve student learning outcomes in Cambodia
