Abstract

Kesenjangan yang signifikan antara produksi garam nasional dan tingginya kebutuhan garam industri menyebabkan ketergantungan Indonesia pada impor. Perancangan Tugas Akhir ini bertujuan untuk mendesain Pabrik Garam Industri berbasis garam rakyat dengan kapasitas produksi 200.000 ton/tahun demi mendukung program swasembada garam nasional. Berdasarkan analisis komparatif parameter proses, kondisi operasi, kebutuhan energi, serta keekonomian, metode washing SALEX® (Salt Extraction) terpilih sebagai teknologi utama. Metode pencucian counter-current menggunakan brine jenuh ini mampu menghasilkan garam dengan kemurnian tinggi (mencapai 99,77% NaCl) tanpa penggunaan steam, sehingga lebih hemat energi dibandingkan proses rekristalisasi. Penentuan lokasi pabrik dilakukan menggunakan metode Analytical Hierarchy Process (AHP) yang menetapkan Kabupaten Indramayu, Jawa Barat sebagai lokasi terpilih berdasarkan ketersediaan bahan baku, aksesibilitas pasar industri (CAP), dan infrastruktur pendukung. Perancangan pabrik meliputi deskripsi proses, Process Flow Diagram (PFD), neraca massa dan energi, hingga analisis ekonomi. Produk akhir yang dihasilkan berupa kristal garam berukuran 30 mesh dengan kemurnian 99,8% setelah pengeringan. Pabrik direncanakan beroperasi selama 330 hari/tahun dengan umur ekonomis 15 tahun. Hasil evaluasi kelayakan ekonomi menunjukkan nilai Internal Rate of Return (IRR) sebesar 28,05%, Payback Period (POT) 3,72 tahun, dan Net Present Value (NPV) positif sebesar Rp376.164.005.802,39, yang membuktikan bahwa pabrik garam industri ini sangat layak untuk didirikan.

Indonesia faces a substantial disparity between national salt production and high industrial salt demand, leading to heavy import reliance to fulfill industrial quality standards. This Final Project aims to design an Industrial Salt Plant with a production capacity of 200,000 tons/year using local traditional salt as the primary raw material to support the national salt self-sufficiency initiative. Through a comparative evaluation of process parameters, operating conditions, energy efficiency, and economic viability, the SALEX® (Salt Extraction) washing process was selected. This counter-current washing technology utilizes saturated brine to achieve high-purity salt (up to 99.77% NaCl) with lower energy consumption (steam-free) compared to conventional recrystallization methods. Utilizing the Analytical Hierarchy Process (AHP), Indramayu Regency, West Java, was designated as the optimal plant site due to its raw material availability, proximity to industrial end-users (CAP), and supporting infrastructure. The plant design incorporates comprehensive process descriptions, Process Flow Diagrams (PFD), mass and energy balances, and economic feasibility studies. The final output yields salt crystals with a post-drying purity of 99.8% and a particle size reduced to 30 mesh. Designed for a operational timeframe of 330 days per year across a 15-year plant lifespan, the economic evaluation demonstrates an Internal Rate of Return (IRR) of 28.05%, a Payback Period (POT) of 3.72 years, and a positive Net Present Value (NPV) of IDR 376,164,005,802.39, confirming the commercial and technical feasibility of the proposed plant.
