ABSTRAK/ABSTRACT

PT Amarilys Karisma Gemilang merupakan perusahaan manufaktur plastic injection molding yang membutuhkan sistem pemantauan energi listrik akurat guna meningkatkan efisiensi operasional. Konsumsi energi yang tidak terpantau secara optimal berpotensi meningkatkan biaya operasional dan mengganggu kinerja mesin. Penelitian ini bertujuan merancang sistem pengambilan data energi listrik pada power meter Schneider iEM3255 menggunakan arsitektur Industrial Gateway berbasis komunikasi Modbus RTU yang terintegrasi dengan platform web. Power meter Schneider iEM3255 mengukur parameter penting seperti tegangan, arus, daya aktif, faktor daya, dan energi kumulatif, namun belum dilengkapi sistem pemantauan jarak jauh. Pengujian awal menggunakan ESP32 mengalami kendala interferensi sinyal (noise). Oleh karena itu, arsitektur final diimplementasikan menggunakan converter USR-TCP232-410S dan Raspberry Pi 4. Sistem ini menjembatani transmisi data via kabel Ethernet menuju cloud database Supabase dan ditampilkan pada web dashboard Vercel secara real-time. Hasil pengujian menunjukkan sistem mampu membaca data energi secara akurat dengan deviasi selisih di bawah 1% serta mencapai reliabilitas transmisi data sebesar 99,3% di lingkungan pabrik. Sistem ini mempermudah evaluasi konsumsi energi tiap mesin dan mendukung pengembangan sistem manajemen energi perusahaan secara presisi.

PT Amarilys Karisma Gemilang is a plastic injection molding manufacturing company that requires an accurate electrical energy monitoring system to support operational efficiency in the production process. Unmonitored energy consumption can lead to high operational costs and hinder machine efficiency improvements. Therefore, this study aims to design and implement an electrical energy data acquisition system on a Schneider iEM3255 power meter using an Industrial Gateway architecture based on Modbus RTU communication integrated with a web-based platform. The Schneider iEM3255 power meter measures critical electrical parameters such as voltage, current, active power, power factor, and cumulative energy, but lacks a flexible remote monitoring capability. Initial testing using an ESP32 encountered signal noise interference from factory machinery. Consequently, the final architecture was implemented using an USR-TCP232-410S industrial converter and a Raspberry Pi 4. This architecture bridges data transmission via Ethernet LAN cables to a Supabase cloud database and displays real-time parameters on a Vercel web dashboard. The results show that the developed system accurately reads electrical energy data with a margin of error under 1% and achieves a data transmission reliability of 99.3% in a factory environment. This monitoring system enables real-time machine energy evaluation and supports precise energy-saving strategies.
