Abstract
Proses produksi pada industri manufaktur memerlukan efisiensi pada proses pengiriman dan seleksi bahan produksi. Saat ini sering dijumpai penggunaan komponen masih dilakukan secara manual sehingga membutuhkan pemantauan operator secara intensif, sedangkan manusia memiliki keterbatasan sumber daya. Oleh karena itu, salah satu cara yang digunakan adalah dengan menggunakan konveyor, cane crane dan vaccum pad yang dioperasikan secara otomatis. PLC merupakan kontroler yang diguakan untuk mengotomatiskan sistem. Bahasa pemrograman PLC yang digunakan pada penelitian ini adalah diagram ladder. Sering dijumpai konstruksi diagram ladder masih didasarkan pada logika programer, hal ini menyebabkan kurang terstrukturnya diagram ladder yang akan menyulitkan problem solving. Oleh karena itu diguakan metode petri net untuk merancang konstruksi diagram ladder sebagai referensi program. Hasil diagram ladder di download ke PLC melalui PC menggunakan kabel serial RS-232 dan diimplementasikan ke plant factory automatic trainer (FAT) sebagai representasi dari proses produksi di industri manufaktur. Konstruksi diagram ladder yang dihasilkan adalah 36 rung proses dengan penambahan 10 timer dan 13 memory (relay). Waktu yang dibutuhkan untuk sekali proses produksi benda kerja 1 rata-rata 28,60 detik dan benda kerja 2 rata-rata 29,92 detik. Jadi untuk satu siklus proses otomasi rata-rata 29,26 detik.

The production process in the manufacturing industry now requires efficiency in the shipping and selection process of production materials. Currently often encountered the use of components is still done manually so it requires intensive operator monitoring, while humans have limited resources. Therefore, one of the ways used is to use conveyor, cane crane and vaccum pad which is operated automatically. PLC is the controller used to automate the system. PLC programming language used in this study is a ladder diagram. Often encountered ladder diagramming constructs are still based on programmer logic, this leads to a less structured ladder diagram that will complicate the problem solving. Therefore it is used Petri net method to design ladder diagram construction as reference program. The results of ladder diagram construction are downloaded to PLC through PC using serial RS-232 cable and implemented to plant factory automatic trainer (FAT) as a representation of production process in manufacturing industry. The construction of the resulting ladder diagram is 36 rung processes with the addition of 10 timers and 13 memory addresses. The time required for one workpiece production process 1 averages 28.60 seconds and the workpiece 2 averages 29.92 seconds. So for one cycle the process of automation averages 29.26 seconds.
