Abstract

Pada Bulan Juni 2020 terdapat claim di customer TMMIN (PT Toyota Motor Manufakturing Indonesia) untuk produk horn assy. Claim-nya adalah part number pada kartu identitas customer berbeda dengan part number horn assy. Oleh karena itu dibuatlah otomatisasi sistem pokayoke kanban cek dengan QR code scanner sebagai media indikator untuk mendeteksi kanban salah (campur) untuk memudahkan pekerjaan pengecekan kanban oleh foreman dan inspektor menggunakan visual basic, arduino, dan konveyor, dimana data dari kanban akan terekam dalam database di komputer. Otomatisasi sistem pokayoke pengecekan kanban terintegrasi di lokasi foreman dan inspektor, berhasil menurunkan rasio produk NG (Not Good) dari pengecekan manual, pada area foreman dari 3.3% menjadi 0% dan pada area inspektor dari 1.7% menjadi 0%.

Abstract

ABSTRAKKendali ketinggian air merupakan suatu sistem yang sering ditemukan di sebagian besar fasilitas industri. Kendali ketinggian air seringkali dihadapkan pada gangguan yang disebabkan perubahan aliran masuk serta perubahan laju pengeluaran air. Penelitian ini bertujuan untuk meningkatkan kendali ketinggian air dalam sistem dengan kendali Fuzzy PID dalam menghadapi variasi gangguan berupa perubahan laju pengeluaran air, serta mengimplementasikan pada kontroler PLC. Penelitian ini melibatkan pengujian kendali Fuzzy PID dan kendali PID dengan metode tuning Ziegler-Nichols 1. Variasi gangguan berupa keluaran pompa DC yang bisa diatur kecepatannya dari Output DA PLC resolusi 0-6000 yang dikonversi menjadi 0-100%. Hasil penelitian menunjukkan Fuzzy PID dapat diimplementasikan pada PLC dengan hasil yang minim overshoot, settling time yang lebih pendek rata-rata 17.23 detik sedangkan PID rata-rata 78,4 detik dan terdapat overshoot. Namun, Fuzzy PID cenderung memiliki rise time lebih lambat 1-2 detik daripada kendali PID.Kata kunci: PLC, Fuzzy PID, PID, Water Level, Ziegler-Nichols ABSTRACTWater level control is a system that is often found in most industrial facilities. Water level control is often faced with disturbances caused by changes in the inflow and changes in the rate of discharge of water. This study aims to improve the control of the water level in a system with Fuzzy PID control in dealing with variations in disturbances in the form of changes in the rate of water discharge, and to implement it on the PLC controller. This study involves testing Fuzzy PID control and PID control using the Ziegler-Nichols 1 tuning method. The disturbance variation is in the form of a speed-adjustable DC pump output from the PLC DA Output with a resolution of 0-6000 which is converted to 0-100%. The results showed that Fuzzy PID can be implemented on PLCs with minimal overshoot results, shorter settling time with an average of 17.23 seconds while the average PID is 78.4 seconds and there is overshoot. However, Fuzzy PID tends to have a slower rise time of 1-2 seconds than PID control.Keywords: PLC, Fuzzy PID, PID, Water Level, Ziegler-Nichols

Abstract

The availability of data loggers as data acquisition is still limited to sensor levels and the data loggers have not been produced in Indonesia. This makes it difficult for monitors to obtain data such as water pressure and water discharge data. The solution to this problem is to reduce the import cost of purchasing data loggers from abroad by developing data loggers that are able to take data on water level, water pressure. This study aims to determine how the design and performance of data logger system substitution products flow and water pressure using LoRa WAN communication. The test results show that the Water Flow and Pressure Data logger System functions according to the design that has been made with error readings from the itron cyble sensor of ?? and a pressure sensor reading error of 20.66%. The Packet Loss value of sending data from the data logger device is directly proportional to the distance where the smallest packet loss value is 13% at a distance of 50m and 80% at a distance of 2800m.
