Abstract

Plant pebble quick lime di PT Uniserv merupakan bagian akhir proses pengolahan batu kapur yang melibatkan berbagai peralatan material handling yang saling bergantung. Kondisi eksisting menunjukkan bahwa sistem operasi belum memiliki mekanisme Sequence dan interlock otomatis yang terintegrasi, sehingga gangguan pada satu peralatan dapat menyebabkan penumpukan material, penghentian proses produksi, serta meningkatkan risiko kerusakan peralatan. Oleh karena itu, diperlukan sistem pengendalian yang mampu mengatur urutan operasi dan menjamin keterkaitan antarperalatan secara otomatis untuk meningkatkan keandalan dan keselamatan proses. Penelitian ini bertujuan merancang dan mengimplementasikan sistem keaManan operasi menggunakan metode Look Up Table sebagai dasar penentuan Sequence dan interlock antarperalatan. Sistem dikembangkan menggunakan Programmable Logic Controller Siemens ET200SP dan Aveva InTouch sebagai antarmuka monitoring dan pengendalian. Implementasi dilakukan melalui perancangan logika Sequence control, interlock, alarm, serta komunikasi Modbus TCP/IP untuk mendukung pemantauan kondisi Plant secara real-time . Pengujian dilakukan pada tiga kelompok Sequence yang melibatkan conveyor, bucket elevator, crusher, hammer mill, rotary feeder, dan peralatan pendukung lainnya. Hasil penelitian menunjukkan bahwa sistem berhasil mengimplementasikan Sequence dan interlock sesuai dengan alur proses yang dirancang. Seluruh skenario pengujian dapat dijalankan berdasarkan kondisi permissive dan interlock yang telah ditetapkan. Pengujian komunikasi PLC menghasilkan rata-rata waktu respons sebesar 0,57 ms, sedangkan waktu respons pengoperasian peralatan berada pada rentang 0,46–1,00 ms. Sistem juga mampu menghentikan operasi secara otomatis ketika terjadi hilangnya sinyal permissive, overload, maupun aktivasi emergency stop. Dengan demikian, sistem yang dikembangkan mampu meningkatkan keandalan operasi, menjaga kontinuitas aliran material, serta mendukung keselamatan proses pada Plant pebble quick lime PT Uniserv.

The Pebble quick lime Plant at PT Uniserv represents the final stage of the limestone processing operation, involving various interdependent material-handling units. Current conditions reveal the absence of an integrated Automatic Sequencing and interlocking mechanism; conSequently, a malfunction in a single piece of Equipment can lead to material accumulation, production stoppages, and an increased risk of Equipment damage. Therefore, a control system is required to Automatically Manage operational Sequences and ensure Equipment interdependency, thereby enhancing process reliability and safety. This study aims to design and implement an operational safety system utilizing the Look-Up Table method to determine Equipment Sequencing and interlocking logic. The system was developed using a Siemens ET200SP Programmable Logic Controller and Aveva InTouch for monitoring and control interfacing. Implementation involved designing logic for Sequence control, interlocks, and alarms, as well as configuring Modbus TCP/IP communication to facilitate real-time Plant monitoring. Testing was conducted across three Sequence groups involving conveyors, bucket elevators, a crusher, a hammer mill, a rotary feeder, and other auxiliary Equipment. The results demonstrate that the system successfully implemented Sequencing and interlocks in accordance with the designed process flow. All test scenarios were executed successfully based on the established permissive and interlock conditions. PLC communication testing yielded an average response time of 0.57 ms, while Equipment operation response times ranged from 0.46 to 1.00 ms. The system also demonstrated the capability to Automatically halt operations in the event of a lost permissive signal, an overload condition, or emergency stop activation. Thus, the developed system enhances operational reliability, maintains material flow continuity, and supports process safety at PT Uniserv’s Pebble quick lime Plant.
