Abstract

Dalam proses produksi dan distribusi pada bidang industri, diperlukan alat produksi yang dapat beroperasi secara efisien bagi petugas operator. PT Petrokimia Gresik merupakan salah satu produsen pupuk yang berusaha mengunggulkan sistem proses produksi dan distribusi yang berkaca dari pengalaman perancangan sistem sebelumnya. Pada sistem distribusi amonia cair sebelumnya masih dioperasikan dengan cara manual, serta masih sering terjadi ketidaksesuaian volume distribusi amonia.
Untuk mengatasi ketidaksesuaian dari loading volume amonia, penulis membuat penelitian inovasi berupa sistem kontrol volume loading amonia menggunakan metode PID. Pusat kendali pada sistem kontrol tersebut menggunakan programmable logic controller Outseal sebagai modbus master, serta ATmega328 ESP-8266 sebagai modbus slave. Modbus master berfungsi sebagai pengontrol motor servo, pompa, sensor flowmeter dan sensor level. Pengiriman data dari modbus slave sebagai pengaturan input nilai setpoint volume dioperasikan menggunakan keypad. Modbus slave juga digunakan untuk input data ke database dan website.
Hasil dari penelitian ini adalah suatu sistem kontrol volume loading amonia menggunakan metode PID yang digunakan untuk mempertahankan laju aliran amonia tetap pada keadaan konstan, serta operator dapat melakukan monitoring hasil loading amonia tersebut pada website. Sistem kontrol loading amonia tersebut menghasilkan nilai rise time 53,9 detik, settling time 123 detik, nilai overshoot 1,03, serta adanya nilai error sebesar 3%. Untuk pembacaan flowmeter, dilakukan percobaan sebanyak 30 kali dengan nilai setpoint dari 1 liter sampai 10 liter dan memiliki nilai eror dengan rata-rata sebesar 1,89%.

The operator need production equipment that can operate efficiently in the production and distribution process. PT Petrokimia Gresik is a company that seeks to be the best in the industry in terms of the production and distribution process system, based on past system design experience. The previous liquid ammonia distribution system was still manually operated, and the ammonia distribution volume was still inaccurate.
To resolve the disparity in ammonia volume distribution, the authors conducted an innovation research in the form of an ammonia loading volume control system based on the PID approach. The Outseal programmable logic controller acts as the modbus master in the control system, while the ATmega 328 and ESP-8266 act as modbus slaves. The modbus master has become a servo motor controller, a pump, a flowmeter sensor, and a level sensor all in one. The keypad is used to send data from the modbus slave as the input setting of the volume setpoint value. Modbus slave is frequently used to update databases and websites with information.
The ammonia loading volume control system developed as a result of this research uses the PID method to maintain a constant water flow rate, and the operator can monitor the ammonia loading results on the website. The ammonia loading control system has a rise time of 53.9 seconds, a settling time of 123 seconds, an overshoot value of 1.03, and a 3% error value. Experiments have been conducted 30 times with a setpoint of 1 liter to 10 liters for flowmeter sensor readings with the YF-S201 type, and the average error value was 1.89%.
