Abstract

Indonesia menghadapi tantangan signifikan dalam memenuhi kebutuhan garam industri nasional, khususnya untuk sektor strategis seperti Chlor Alkali Plant (CAP), dengan tingkat ketergantungan impor yang masih tinggi. Untuk mendukung program swasembada garam pemerintah pada tahun 2027, diperlukan pendirian pabrik garam industri berteknologi tinggi. Tugas akhir ini bertujuan untuk merancang pabrik garam industri dengan kapasitas produksi 25.000 ton per tahun, yang dapat memenuhi sekitar 0,89% dari proyeksi kebutuhan impor nasional pada tahun 2026. Berdasarkan analisis mendalam terhadap berbagai teknologi produksi menggunakan metode Analytical Hierarchy Process (AHP), proses utama yang dipilih adalah Mechanical Vapor Recompression (MVR) yang dikombinasikan dengan proses pre-treatment sendimentasi. Teknologi ini dipilih karena efisiensi energinya yang tinggi, biaya operasional yang rendah, dan kemampuan menghasilkan produk dengan kemurnian NaCl di atas 97,5%, yang memenuhi standar SNI untuk garam industri. Analisis kelayakan lokasi menetapkan Kabupaten Sampang, Jawa Timur, sebagai lokasi terbaik untuk pendirian pabrik. Pemilihan ini didasakan pada pertimbangan ketersediaan bahan baku air laut, kedekatan dengan pasar industri utama di Jawa, aksesibilitas transportasi (pelabuhan), ketersediaan utilitas (listrik), serta dukungan regulasi dan tenaga kerja. Analisis ekonomi menunjukkan kelayakan proyek dengan nilai IRR sebesar 13,10%, POT 5,6 tahun, dan NPV positif. Oleh karena itu, rancangan pabrik ini tidak hanya layak dari segi tekno-ekonomi tetapi juga strategis dalam mendukung ketahanan industri nasional dan mengurangi ketergantungan pada impor garam.

Indonesia faces significant challenges in meeting its national industrial salt needs, paarticularly for strategic sector such as Chlor Alkali Plants (CAP), with a hhigh level of import depedency. To support the government's salt self-sufficiency program in 2027, it is necessary to eblishh a highh-tech industrial salt factory. This final project aims to design an industrial salt factory with a production capacity of 25.000 tons per year, which can eet approximately 0,89% of the projected national import needs in 2026. Bassed on an in-depth analysis of various production technologies using the Analytical Hierarchy Process (AH) method, the main process selected is Mechanical Vapor Recompression (MVR) combined with a sendimentation pre-treatment process. This Technology was chosen for its high energy efficiency, low operating costs, and ability to produce products with a NaCl purity above 97,55%, which meets SNI Standards for industrial salt. The location feasibility analysis determined Sampang Regency, East Java, as the best location for the factory. This selection was based on considerations of the availability of seawater raw materials, proximity to major industrial markets in Java, transportation accessibility (ports), availability of utilities (electricity), as well as regulatory and labor support. The economic analysis shows the feasibility of the project with an IRR of 13,10%, POT of 5,60 years, and a positive NPV. Therefore, the factory design is not only feasible from a techno-economic perspective but also strategic in supporting national industrial resilience and reducing dependence on salt imports.
