Abstract

Indonesia menghadapi kesenjangan signifikan antara produksi garam nasional dan tingginya kebutuhan garam industri, yang mengakibatkan ketergantungan besar pada impor untuk memenuhi standar kualitas industri. Tujuan dari Tugas Akhir ini adalah untuk merancang Pabrik Garam Industri dengan kapasitas 200.000 ton/tahun yang berbahan baku garam rakyat. Berdasarkan analisis perbandingan parameter proses, kondisi operasi, kebutuhan energi, ekonomi, dan kemurnian produk, metode ‘washing’ yang terpilih adalah proses SALEX® (Salt Extraction). Metode ini merupakan teknologi pencucian counter-current dengan brine jenuh yang dipilih karena kemampuannya menghasilkan garam kemurnian sangat tinggi (mencapai 99,77% NaCl) dengan konsumsi energi lebih rendah (tanpa steam) dibandingkan proses rekristalisasi. Melalui metode Analytical Hierarchy Process (AHP), lokasi pabrik ditetapkan di Kabupaten Indramayu, Jawa Barat, dengan mempertimbangkan faktor ketersediaan bahan baku, kedekatan dengan pasar industri (CAP), dan infrastruktur pendukung. Perancangan pabrik ini mencakup uraian proses, diagram alir proses (PFD), neraca massa dan energi, serta analisis ekonomi untuk mendukung program swasembada garam nasional. Kristal garam memiliki kemurnian 99,8% setelah pengeringan selesai dan akan direduksi ukurannya hingga mencapai 30 mesh. Pabrik garam industri ini memiliki waktu operasi 330 hari kerja pada usia pabrik 15 tahun. Dengan laju pengembalian modal atau IRR sebesar 28,06% didapatkan waktu pengembalian modal (POT) sebesar 3,72 tahun, dan NPV positif sebesar Rp376.259.928.146,26 yang menunjukkan bahwa pabrik garam industri ini layak didirikan.

Indonesia faces a significant gap between national salt production and high industrial salt demand, resulting in heavy dependence on imports to meet industrial quality standards. The objective of this Final Project is to design an Industrial Salt Plant with a capacity of 200,000 tons/year using traditional salt as raw material. Based on a comparative analysis of process parameters, operating conditions, energy requirements, economics, and product purity, the selected ‘washing’ method is the SALEX® (Salt Extraction) process. This method is a counter-current washing technology with saturated brine, chosen for its ability to produce very high purity salt (reaching 99.77% NaCl) with lower energy consumption (without steam) compared to the recrystallization process. Through the Analytical Hierarchy Process (AHP) method, the factory location was determined to be in Indramayu Regency, West Java, considering factors such as raw material availability, proximity to industrial markets (CAP), and supporting infrastructure. The factory design includes a process description, process flow diagram (PFD), mass and energy balance, and economic analysis to support the national salt self-sufficiency program. The salt crystals have a purity of 99.8% after drying is complete and will be reduced in size to 30 mesh. This industrial salt factory has an operating time of 330 working days over the 15-year lifespan of the factory. With an internal rate of return (IRR) of 28.06%, the payback period (POT) is 3.72 years; and a positive net present value (NPV) of IDR 376,259,928,146.26, indicating that this industrial salt factory is feasible to establish.
