Abstract

As industries seek to improve product quality and reduce costs, automation tools like 3-phase induction motors have become indispensable due to their simplicity, cost-effectiveness, efficiency, and ease of maintenance. This study investigates the automation of monitoring for 3-phase induction motors through the integration of various components, including the A3114 Hall Effect sensor, PZEM-PP4T sensor, 20x4 LCD, ESP32 module, relay, Mitsubishi D700 inverter, and MCP 4725 sensor. Testing results show high accuracy in measuring critical motor parameters such as speed, voltage, and current. The Hall Effect sensor demonstrated an average accuracy of 4.12% compared to a tachometer, while the PZEM sensor exhibited a 0.90% accuracy for voltage and a 0.98% accuracy for current when compared to a multimeter, affirming the reliability of the system. Overall, the system provides consistent and precise measurements, transforming manual monitoring into an efficient automated process. This advancement significantly enhances the reliability and effectiveness of 3-phase motor monitoring in industrial applications

Abstract

Latar Belakang: Penurunan kinerja main air compressor tipe J.P Sauer & SOHN WP 81L-100 di kapal MV. Tangguh Sago menjadi masalah serius yang dapat menghambat operasional kapal secara keseluruhan. Compressor ini memiliki peran penting sebagai sumber utama udara bertekanan yang digunakan untuk berbagai kebutuhan vital, termasuk sistem pneumatik kapal dan pengoperasian mesin utama. Tujuan: Penelitian ini bertujuan untuk menganalisis penyebab penurunan kinerja compressor dan merumuskan solusi perawatan yang efektif. Metode: Metode yang digunakan dalam penelitian ini adalah metode kualitatif dengan pendekatan fishbone (diagram tulang ikan) untuk mengidentifikasi akar masalah. Pengumpulan data dilakukan melalui observasi langsung, wawancara dengan awak kapal, serta dokumentasi terkait perawatan dan performa compressor Hasil: Hasil analisis fishbone menunjukkan bahwa penurunan kinerja compressor disebabkan oleh beberapa faktor utama, yaitu keausan komponen, kurangnya perawatan preventif, penumpukan kotoran pada bagian internal, dan rendahnya pemahaman awak kapal mengenai prosedur perawatan yang benar. Kesimpulan: Kesimpulan dari penelitian ini menekankan pentingnya perawatan yang lebih terstruktur serta peningkatan pemahaman teknis bagi awak kapal guna memulihkan kinerja optimal kompresor. Penelitian ini merekomendasikan peningkatan kesadaran awak kapal tentang pentingnya menjaga kinerja kompresor udara, disertai dengan penambahan frekuensi pengecekan rutin untuk mencegah terjadinya penurunan kinerja di masa mendatang

Abstract

: Air compressors serve as vital auxiliary engines on ships for starting main engines and operating valves, yet manual monitoring leads to inefficiencies and frequent failures, contributing to 20% of machinery downtimes globally. This study aims to design and build a prototype air compressor with ESP32-based microcontroller monitoring system for real-time electrical parameter tracking. Employing an experimental prototype development design, the research utilized laboratory-scale prototype as subject, with hardware including PZEM-004T sensor, LCD I2C, and Blynk app; data analyzed via comparative quantitative measurements against standard multimeter for accuracy assessment. Results demonstrate 100% consistency in voltage (230V), current (6.1A), power (1015W), and frequency (50Hz) readings across LCD and remote app during static/dynamic tests. In conclusion, the prototype enhances predictive maintenance and educational training for maritime students, although field testing in harsh conditions is recommended
