Abstract

This study aimed to analyze the effect of the Sciedugame Mobile application on the development of students’ progressive scientific literacy in junior high school science learning. A quasi-experimental design was employed with two eighth-grade classes at SMP Negeri 56 Surabaya. The experimental class used the Sciedugame Mobile application, while the control class received conventional instruction. Data were collected through pre-test and post-test assessments, classroom observations, and student questionnaires. The results showed that the experimental group achieved higher learning gains than the control group. The average post-test score in the experimental class was 68.38, compared to 58.48 in the control class. The normalized gain (N-Gain) in the experimental group was 0.49 (moderate), while the control group scored 0.36. A t-test confirmed a significant difference between the two groups (tcount = 1.87 > ttable = 1.67 at α = 0.05). In addition, scientific literacy indicators—such as conceptual understanding, scientific process skills, and real-life application—improved more significantly in the experimental class. Observation results also indicated higher implementation quality in the experimental group (97.44%) compared to the control group (76.92%). Furthermore, student responses toward the application were overwhelmingly positive in terms of usability, content clarity, and engagement. These findings suggest that Sciedugame Mobile is a promising mobile learning tool to support progressive scientific literacy in science education.

Abstract

Nutritional status is a key indicator in assessing individual health that can be determined through anthropometric measurements, particularly height and weight. This study uses a design approach that aims to design and implement a wireless system for measuring nutritional status based on Body Mass Index (BMI) using a TOF400C sensor and a Load Cell controlled by an ESP32 microcontroller. The TOF400C sensor measures height based on the Time-of-Flight principle of infrared light, while the Load Cell measures weight with the HX711 module. Data from both sensors is processed by the ESP32 to calculate BMI and categorize nutritional status according to WHO standards. Test results on 10 adult subjects showed an accuracy of 99.6% for the height measuring device and 98.3% for the weight measuring device compared to standard devices, as well as real-time results displayed on OLED and TFT screens. This system is expected to be a practical and efficient solution for digital nutritional status monitoring.

Abstract

This study aims to develop an Electronic Semester Learning Plan (E-RPS) application based on the Outcome-Based Education (OBE) curriculum to address challenges in curriculum management, such as unstructured data, non-uniform standards, and inefficiencies in manual preparation. The study employed the Research and Development (R&D) approach using the ADDIE model (Analyze, Design, Develop, Implement, Evaluate). Data collection included interviews, questionnaires, and documentation, with respondents selected using a snowball sampling technique. Application performance was tested using black-box and beta testing methods, with Likert-scale-based questionnaires for user feedback. Data analysis focused on usability, functionality, and efficiency. The E-RPS application integrates curriculum elements (CPL, CPMK, and Sub-CPMK) and standardizes the RPS preparation process. It automates workflows, enhances data accessibility, and provides collaborative features for lecturers and administrators. Testing results showed an average user satisfaction rate of 87%, validating the application's effectiveness in improving the quality and accuracy of RPS preparation, aligning with OBE principles. This research provides a practical solution to streamline RPS preparation, enhance transparency in curriculum management, and support international accreditation efforts. The findings contribute to the theoretical understanding of integrating technology with OBE frameworks and offer a replicable model for higher education institutions aiming to improve curriculum quality and compliance

Abstract

This study explores persistent misconceptions among students in physics education programs regarding the Special Theory of Relativity. Despite formal instruction, many still show fragmented understanding, often reverting to classical concepts. The aim is to identify dominant misconceptions and analyze cognitive and pedagogical causes. Using a qualitative descriptive method, 25 fifth-semester physics education students from a public university in Indonesia participated. Data were collected through a validated 20-item multiple-choice diagnostic test and semi-structured interviews. Analysis involved data reduction, narrative development, and expert triangulation. Results show frequent misconceptions in time dilation (72%), length contraction (64%), and simultaneity (60%). Students misinterpret time dilation as an absolute change, view length contraction as permanent, and fail to understand simultaneity’s relativity. Contributing factors include limited visual aids, inadequate contextual teaching, and lack of engaging media. To address this, the study suggests using digital tools like simulations and animations and adopting constructivist-based strategies. These are expected to deepen understanding and correct misconceptions. The findings aim to enhance modern physics teaching at the tertiary level.

Abstract

The development of information and communication technology has become an important element in supporting all organizational activities, one of which is a religious institution such as GMIT Petra Kefamenanu. This church utilizes the internet network to support worship activities, administration, and educational services. However, the increasing needs and number of users cause slow connections and the emergence of network security risks. Based on these conditions, this study aims to design and implement an optimal and secure network infrastructure blueprint using a firewall as a network security system and a Network Development Life Cycle (NDLC) approach as a development method. This research was conducted through five NDLC stages: network requirements analysis, design, blueprint , simulation using Cisco Packet Tracer , configuration implementation with Mikrotik, and monitoring. The results of the study show that the network design based on star technology (star topology) and firewall configuration that includes DHCP, NAT, and Layer 7 Protocol features successfully increased overall security and connection efficiency. The firewall is able to limit unproductive access and prevent potential cyber threats. This implementation proves that the blueprint is designed not only for a systematic and extensive network structure, but also provides comprehensive network protection against external attacks, thus supporting more effective church services.
