Abstract

Programmable Logic Controller (PLC) adalah suatu sistem kontrol yang menyempurnakan kelemahan-kelemahan dari sistem kontrol dengan menggunakan relai. PLC hanya dapat menerima input berupa sinyal digital, namun sinyal analog dapat diproses oleh PLC bila telah dikonversikan ke sinyal digital menggunakan Analogue to Digital Converter (ADC). Sebuah PLC mempunyai empat buah komponen utama, yaitu Central Processing Unit (CPU), programmer, input modul dan ouput modul. PLC pada saat ini memerlukan kemampuan yang baik karena di harapkan di dalam proses kerja mampu mengoptimalkan kerja dan meningatkan proses produksi, di samping itu juga memiliki kehandalan untuk dipahami penguna dalam mengoperasikan nya atau saat terjadi kesalahan. Mesin bagging yang ada di PT. PETROKIMIA Gresik merupakan mesin yang digunakan sebagai alat untuk mengisikan pupuk kedalam sak pupuk seberat 50 Kg. Dari data yang di dapat bahwa mesin mampu memproduksi pupuk sebanyak 14 dalam waktu bekisar 4,2 detik. Sensor yang digunakan load cell dan di inovasikan dengan proximity sensor untuk meningkatkan efisiensi serta keamanan bagi pengguna. Pada perencanaan ini menggunakan aksi berbentuk PID di karenakan membutuhkan untuk mencapai set point dengan waktu yang singkat dan meminimalisir error yang terjadi. Dapat disimpulkan bagging merupakan close loop control system, sirkuit pneumatik dan sirkuit listrik telah sesuai dengan ladder diagram terbukti alat mampu di operasikan sejalan dengan rancangan kerja, dan pengmodifikasian terhadap sistem berhasil dilakukan dengan menambahkan proximity sensor. ============================================================================================================== Programmable Logic Controller (PLC) is a control system that complements the weaknesses of the control system using the relay. PLC can only receive input in the form of a digital signal, yet analog signals can be processed by the PLC when it is converted into a digital signal using the Analogue to Digital Converter (ADC). A PLC has four main components, namely the Central Processing Unit (CPU), programmer, input modules and output modules. PLC at this time requires a good ability as expected in the working process is able to optimize the work and meningatkan production process, in addition, it also has the reliability to understand user to operate his or when an error occurs.Bagging machine in PT. PETROKIMIA Gresik is a machine used as a tool for loading fertilizer into sacks of 50 Kg. This thesis is to redesign the control system for the control of automatic bagging machines using PLC. The planning process control system is based on the sequence that occurs in any components on the bagging machine. Bagging machine in PT. PETROKIMIA Gresik is a machine used as a tool for loading fertilizer into sacks of fertilizer weighing 50 Kg. From the data in the can that the machine is capable of producing fertilizer as many as 14 in 4.2 seconds. The sensors used in the load cell and innovate with a proximity sensor to improve the efficiency and safety for the user. At this planning using PID in the form of action because of needing to reach set point with a short time and minimize errors that occur. It can be concluded bagging a closed loop control system, pneumatic circuits and electrical circuits in accordance with the ladder diagram proven tool able to be operated in accordance with the work plan, and modified the system successfully carried out by adding a proximity sensor.
