Abstract

This study aims to develop and evaluate the feasibility of a Mini Amplifier Training Kit as a practical learning tool to improve the learning outcomes of Grade XI students in the Audio-Video Engineering program. The development was motivated by the limited availability of practical facilities that enable students to gain direct experience in operating and understanding audio amplifier systems. This study employed a Research and Development (R&D) approach using the ADDIE model, consisting of Analysis, Design, Development, Implementation, and Evaluation stages. The developed product was assessed based on validity, practicality, and effectiveness. Expert validation results showed that the material component achieved a score of 96%, while the media component obtained 94%, indicating a very high level of validity and feasibility. The practicality assessment based on student response questionnaires resulted in a positive score of 98%, demonstrating that the training kit is easy to operate and supports practical learning activities effectively. Furthermore, a Paired Sample t-Test produced a significance value of 0.000 (p < 0.05), indicating a significant improvement in students’ learning outcomes after using the training kit. The N-Gain score of 0.55 was categorized as moderate. Overall, the Mini Amplifier Training Kit is highly valid, highly practical, and effective, making it suitable for practical learning in Audio-Video Engineering.

Abstract

Objective: To evaluate baseline student satisfaction, compare service quality between two “Accredited Excellent” vocational engineering programs-S1 Building Engineering Education (PTB) and S1 Mechanical Engineering Education (PTM)-and diagnose operational bottlenecks to align empirical findings with institutional quality assurance and global educational standards. Method: A quantitative comparative-descriptive survey design was conducted with a stratified random sample of N = 422 undergraduate students (PTB N1 = 215 and PTM N2 = 207). Data were collected using a 23-indicator SERVQUAL instrument on a 4-point Likert scale and analyzed using descriptive statistics (Mean, Standard Deviation, Respondent Achievement Degree/TCR), independent-samples t-tests (α = 0.05), and Cohen’s d effect size estimations. Results: Although overall satisfaction reached a “Satisfied” baseline (TCR = 75.47%), inferential testing revealed a statistically significant disparity (p = 0.0429) favoring PTB over PTM. Granular item analysis isolated critical operational bottlenecks in laboratory equipment adequacy (P18), general campus facility accessibility (P23), and administrative responsiveness in facility loan procedures (P16). Novelty: The research shows that top-tier accreditation does not guarantee uniform program-level service delivery, offering a pioneering framework that directly integrates granular SERVQUAL diagnostics into the institutional Internal Quality Assurance System (SPMI-PPEPP cycle) and United Nations Sustainable Development Goal 4 (Targets 4. a and 4.4).

Abstract

Boiler systems operate under high pressure and temperature, requiring reliable monitoring and alarm systems to maintain operational safety. At PT. PG. Rajawali I - PG. Krebet Baru I, the existing alarm system on the Yoshimine II boiler was limited to local notifications, which delayed operator response to abnormal operating conditions. This study aims to develop an instrumentation alarm system based on an Omron CJ2M Programmable Logic Controller (PLC), integrated with Delphi 7 monitoring software and Internet of Things (IoT)-based Telegram notifications, to improve operational safety. The research employed a research and development approach consisting of field observation, identification of critical boiler parameters, alarm logic design, and PLC programming, followed by monitoring interface development, Telegram integration, system testing, and evaluation. The developed system monitors critical parameters, including water level, steam level, de-superheater temperature, and flue gas conditions. The results indicate that the proposed system successfully provides real-time visual monitoring and automatic remote notifications whenever process parameters exceed predefined safety limits. The integration of PLC-based control with digital communication enhances operator responsiveness, supports preventive action, and reduces the risk of operational disturbances. The developed prototype demonstrates the feasibility of integrating industrial automation with digital notification technology to strengthen boiler monitoring and operational safety.
