Abstract
Proses Electro Deposition Painting (EDP) pada industri otomotif merupakan tahapan penting yang berpengaruh terhadap kualitas pelapisan cat dan konsumsi energi. Pada kondisi eksisting, konsumsi energi listrik pada unit SUV dan Pickup tergolong tinggi, serta ketebalan lapisan cat melebihi standar hingga ±18 µm. Penelitian ini bertujuan untuk menstabilkan ketebalan lapisan cat tiap unitnya dan menurunkan konsumsi energi melalui perancangan sistem auto switching anoda berbasis variasi unit. auto switching anoda yaitu sistem otomatis yang dapat mengatur jumlah anoda aktif sesuai dengan variant unit yang sedang diproses. Sistem ini dirancang menggunakan Programmable Logic Controller (PLC) sebagai pengendali utama dan dikombinasikan dengan sensor dan aktuator untuk mendetksi proses dan mengkontrol anoda sesuai kebutuhan. Metode yang digunakan adalah Design of Experiment (DOE) Taguchi dengan faktor tegangan, suhu cat, dan jumlah anoda. Analisis dilakukan menggunakan Signal-to-Noise Ratio untuk menentukan parameter optimal dan ANOVA untuk mengidentifikasi faktor paling berpengaruh. Hasil penelitian menunjukkan bahwa jumlah anoda merupakan factor dominan yang mempengaruhi ketebalan lapisan cat dan konsumsi energi dan kombinasi parameter proses terbaik untuk kedua unit adalah 280V, 4 anoda off, 29°C.

The electro deposition painting (EDP) process in the automotive industry is a critical step that affects both paint coating quality and energy consumption. Under current conditions, electricity consumption for SUV and pickup truck units is relatively high, and the paint layer thickness exceeds the standard by up to ±18 µm. This study aims to stabilize the paint layer thickness for each unit and reduce energy consumption through the design of a unit-variant-based auto switching anode system. The auto switching anode is an automated system that can adjust the number of active anodes according to the variant of the unit being processed. This system was designed using a Programmable Logic Controller (PLC) as the main controller and combined with sensors and actuators to detect the process and control the anodes as needed. The method used was the Taguchi Design of Experiments (DOE) with factors including voltage, paint temperature, and the number of anodes. Analysis was performed using the Signal-to-Noise Ratio to determine optimal parameters and ANOVA to identify the most influential factors. The results of the study show that the number of anodes is the dominant factor affecting paint layer thickness and energy consumption, and the best combination of process parameters for both units is 280 V, 4 anodes off, and 29°C.
