Abstract

Industry is one of the economic sectors that plays a role in processing environmental resources into products with higher utility values. This process includes design activities, industrial engineering, and service provision. Matra Abadi Workshop, a manufacturing industry that in its operations produces harmonic currents in the electric power system network, especially in low-order harmonics such as 3rd, 5th, 7th, 9th, and 11th. To reduce the negative impact of harmonics on the power system, the use of passive harmonic filters is required. Among the types of filters used, single tuned filters are a common choice because of their simple construction and effectiveness in reducing certain order harmonics that exceed the IEEE 512–2014 standard limits. This study discusses the implementation of both types of filters in a manufacturing industry environment. The harmonic reduction process is carried out through filter design and testing using Matlab/Simulink software-based simulations. The simulation results show that after the application of passive filters, the harmonic current levels in all load configurations were successfully suppressed to within the IEEE 512–2014 standard limits. The reduction in Total Harmonic Distortion (THDi) after the application of the single tuned filter was recorded in the range of 17.86% to 11.06%. In addition, there was an increase in the power factor from 0.68 before the filter was installed to 0.91 after the installation, which indicates an improvement in the overall power system performance.

Abstract

The rapid advancement of technology has significantly transformed various sectors, including education, leading to the emergence of e-learning. This approach utilizes electronic media to facilitate faster and more efficient absorption of learning materials by students. One form of e-learning is the Computer Assisted Instruction (CAI) model, which integrates information technology components such as communication tools, audio, video, and images into a cohesive multimedia platform. The implementation of CAI in e-learning enables flexible learning delivery by allowing educators to present instructional content and engage learners interactively, whether in one-on-one sessions or in small groups. This model enhances the learning experience by incorporating tutorials and multimedia presentations. Physics, as a branch of natural science, plays a critical role in shaping human reasoning and intellectual development. It investigates the fundamental elements of the universe, the forces acting upon them, and the resulting interactions, ranging from subatomic particles to cosmic phenomena. Natural Science itself is more than just the accumulation of knowledge in the form of facts or theories—it also involves systematic inquiry and discovery processes. Applying the CAI model in high school physics education, particularly in the topic of straight-motion kinematics, is expected to improve students’ comprehension and conceptual understanding. Based on evaluations from media and subject matter experts, as well as product testing, the instructional media developed has been rated highly feasible, receiving an 86% approval score from users.

Abstract

Purpose of the study: This study aims to design and validate V-LAMOT, a web-based virtual laboratory for three-phase motor starting simulation. The system is intended to address limitations of physical laboratories by providing an accessible and safe environment while maintaining conceptual accuracy and supporting the development of practical motor control skills. Methodology: The study adopted the Systems Development Life Cycle (SDLC) to develop the V-LAMOT platform using HTML5, CSS, JavaScript, and state-machine modeling. The design was guided by Cognitive Load Theory principles. Data were obtained through expert validation instruments and the System Usability Scale (SUS), and analyzed using Shapiro–Wilk tests, one-sample t-tests, Cohen’s d, and Pearson correlation with 30 students. Main Findings: Expert validation indicated high feasibility, with conceptual accuracy reaching a mean score of 4.50/5. SUS evaluation produced an overall score of 78.83 (“Good”), with learnability scoring highest at 82.00. All usability measures were significantly above the benchmark (p < 0.001) with large effect sizes (d > 0.8). A strong correlation between usability and learnability (r = 0.823) suggested effective cognitive load reduction. Novelty/Originality of this study: This study presents an integrated virtual laboratory that combines state-machine modeling with Cognitive Load Theory-based interface design for three-phase motor control. Unlike conventional simulations, V-LAMOT integrates multiple motor starting methods in one environment and empirically links usability, learnability, and cognitive load reduction, advancing virtual laboratory development through systematic integration of technical accuracy and pedagogical principles.

Abstract

Speed-reading ability among students with special needs remains low, with most reading below the expected standard. This study aims to examine the effectiveness of the Problem-Based Learning (PBL) model assisted by Kahoot in improving students' speed-reading ability. A quasi-experimental design with a pretest-posttest control group was employed. The population consisted of students from five special schools (SLB) in Nias Regency. A total of 97 students were selected using purposive sampling and divided into an experimental group (n = 49) and a control group (n = 48). Data were collected through reading speed tests, observation sheets, and student engagement questionnaires. The instruments were validated prior to use. Data were analyzed using PLS-SEM with SmartPLS 4.0. The results indicate that the PBL-Kahoot model significantly improves students' speed-reading ability. Student engagement plays a mediating role, and the model explains a substantial proportion of variance in reading performance. The intervention shows varying effectiveness across different types of special needs, with higher gains observed in certain groups. In conclusion, the integration of PBL and Kahoot effectively enhances speed reading ability through increased student engagement. It is recommended that teachers adopt technology-assisted, student-centered learning models and adapt them to students' specific needs.
