Abstract
PLTU merupakan salah satu pembangkit listrik yang sedang berkembang saat ini. Untuk menghasilkan listrik dengan konstan dan efisien, kinerja PLTU di tentukan oleh proses starting dan proses shutdown. Selain itu, proses pada starting ini juga diperlukan efisiensi yang tinggi. Maka setiap komponen dari proses starting butuh untuk dikontrol secara terus menerus. Dalam melakukan kontrol tersebut, digunakan PLC sebagai controller yang sudah banyak digunakan di industri karena terbukti keandalannya. Untuk dapat memprogram PLC digunakan Diagram Ladder. Namun dalam beberapa kasus, diagram ladder susah untuk dipahami oleh orang lain, sehingga akan lebih sulit untuk menyelaesaikan masalah. Maka, untuk mengatasi itu digunakan sebuah metode dalam pemrograman PLC agar program yang digunakan mampu untuk dipahami orang lain yang bukan programmer. Metode yang digunakan adalah Grafcet, dengan alasan metode ini lebih mudah apabila akan dilakukan modifikasi ladder. Hasil pengujian menunjukkan bahwa program PLC maupun HMI dapat berjalan sesuai dengan yang diinginkan. Hasil Perancangan Ladder Diagram berdasarkan metode Grafcet membutuhkan 56 Relay input dan memori, serta terdapat 25 Relay Output. Diagram Ladder hasil perancangan membutuhkan 38 rung untuk proses, 4 rung tambahan, dan 23 rung output, sehingga total terdapat 66 rung, serta membutuhkan 14 Timer, ukuran file dari diagram ladder adalah 4.46 KB. Waktu rata-rata yang dibutuhkan dalam simulasi untuk menyalakan seluruh komponen adalah 27,1 detik.

PLTU is one of the power plants, that is still conmtinuous to develop. To produce electricity constantly and efficiently, the Steam Power Plant's performance is determined by the starting process and the shutdown process. It is because the starting process is prone to leakage of the pipe and will cause the equipment to rust. In addition, the process in this starting also requires high efficiency. Then each component of the starting process needs to be controlled continuously. In carrying out these controls, PLC is used as a controller which is already widely used in the industry because of its proven reliability. To be able to program a Programmable Logic Control or PLC, a Ladder diagram is used. But in some cases, ladder diagrams are difficult to understand to other people that want to know the flow of the Ladder Diagram, so it will be more difficult to overcome if there are problems in the system. It is used a Grafcet method in PLC programming so that the program used is able to be understood by other people who are not programmers. The test results show that the PLC or Human machine interface or HMI programs can run as desired. By using the Grafcet Method, it is expected that other people will easily understand the program easily. The average time needed in the simulation to turn on all components is 27.1 seconds.
