Abstract
Air deionisasi (Deionized Water/DI Water) merupakan salah satu utilitas penting dalam proses industri karena memiliki kandungan ion terlarut yang sangat rendah sehingga mampu menjaga kualitas produk dan mencegah terjadinya kontaminasi. Laporan ini bertujuan untuk mengkaji sistem pengolahan air deionisasi (DI Water Plant) di PT XYZ Indonesia, meliputi prinsip kerja, komponen utama, alur proses, serta analisis potensi kegagalan menggunakan metode Fault Tree Analysis (FTA). Sistem pengolahan air terdiri atas tahapan Carbon Filter, Water Softener, Reverse Osmosis (RO), dan Mixed Bed Polisher yang bekerja secara terintegrasi untuk menghasilkan air deionisasi dengan kualitas tinggi. Carbon Filter berfungsi menghilangkan senyawa organik, warna, dan bau, Water Softener menurunkan kesadahan melalui proses pertukaran ion, Reverse Osmosis mengurangi total padatan terlarut (TDS) menggunakan membran bertekanan tinggi, sedangkan Mixed Bed Polisher menghilangkan sisa ion sehingga diperoleh air dengan tingkat kemurnian yang memenuhi kebutuhan proses produksi. Selain itu, dilakukan analisis menggunakan metode Fault Tree Analysis untuk mengidentifikasi penyebab dasar kegagalan pada sistem serta menentukan tindakan pencegahan yang tepat. Hasil kajian menunjukkan bahwa kombinasi teknologi Reverse Osmosis dan Mixed Bed Polisher mampu menghasilkan air deionisasi secara konsisten dengan efisiensi operasional yang lebih baik dibandingkan sistem pertukaran ion konvensional. Penerapan sistem ini mendukung keberlangsungan proses produksi melalui penyediaan air berkualitas tinggi serta meningkatkan keandalan operasi dan efektivitas pemeliharaan peralatan.

Deionized water (DI Water) is an essential utility in industrial processes due to its extremely low dissolved ion content, which helps maintain product quality and prevent contamination. This report aims to analyze the Deionized Water (DI Water) Plant system at PT XYZ Indonesia, including its operating principles, main components, process flow, and potential failure analysis using the Fault Tree Analysis (FTA) method. The water treatment system consists of Carbon Filter, Water Softener, Reverse Osmosis (RO), and Mixed Bed Polisher units operating in an integrated process to produce high-purity deionized water. The Carbon Filter removes organic compounds, color, and odor, while the Water Softener reduces water hardness through ion exchange. The Reverse Osmosis unit significantly decreases total dissolved solids (TDS) using high-pressure membranes, and the Mixed Bed Polisher removes the remaining ions to achieve the required water purity for industrial applications. Furthermore, Fault Tree Analysis was applied to identify the root causes of potential system failures and determine appropriate preventive actions. The study indicates that the combination of Reverse Osmosis and Mixed Bed Polisher technologies consistently produces high-quality deionized water with greater operational efficiency compared to conventional ion-exchange systems. The implementation of this system supports production continuity by providing high-purity water while improving operational reliability and maintenance effectiveness.
