Abstract

Nickel plating adalah metode penting untuk meningkatkan ketahanan korosi dan performa produk, terutama dalam pembuatan lampu medis di PT XYZ. Masalah utama dalam proses ini adalah menjaga kestabilan pH larutan, yang sebelumnya dipantau secara manual dan rentan terhadap fluktuasi yang ekstrem. Untuk mengatasi masalah ini, penelitian ini membuat dan mengimplementasikan analisis pH level serta alat monitoring pH real-time yang merekam data secara kontinu, memberikan alarm saat pH keluar dari rentang spesifikasi, dan menampilkan data historis melalui antarmuka web. Hasil pengujian menunjukkan akurasi tinggi dengan rata-rata error kurang dari 2% dan peningkatan efisiensi waktu sebesar 93.75% dibandingkan metode manual. Hasil analisis Pearson correlation menunjukkan tidak ada hubungan signifikan antara waktu dan pH. Analisis I-MR chart pada empat tank mengungkapkan variasi stabilitas pH, dengan tank 10C menunjukkan performa terbaik, sementara tank 10B memerlukan perhatian khusus akibat ketidakstabilan tinggi.
