Abstract
Indonesia memiliki garis pantai terpanjang kedua di dunia serta tiga perempat wilayah Indonesia adalah air laut, Potensi ini dapat dimanfaatkan salah satunya sebagai bahan dasar produksi komoditi garam. Menurut fungsinya, salah satu jenis garam yaitu garam industri, yang memiliki kadar NaCl paling sedikit 97% (dry basis). Kegunaan garam industri diperuntukkan sebagai bahan baku maupun bahan tambahan bagi keperluan industri lain, seperti industri tekstil, farmasi, dan sebagainya. Tingginya kebutuhan garam industri setiap tahunnya yang masih didatangkan dari luar negeri merupakan latar belakang pendirian pabrik garam industri. Proses pembuatan garam industri dibagi menjadi 3 tahapan proses, yaitu pretreatment dan pemurnian bahan baku, pemasakan, dan pengeringan dan pengendalian produk garam industri. Tahap pretreatment bertujuan untuk menghilangkan impuritis dalam air laut yang dapat mengganggu proses selanjutnya menggunakan proses sedimentasi. Tahap pemasakan bertujuan untuk menghilangkan air dan diharapkan produk keluar berupa wet crystal. Proses pengeringan dilakukan untuk mendapatkan produk kristal garam industri dengan kadar NaCl 99,6%. Pabrik direncanakan beroperasi pada tahun 2023. Berdasarkan data impor, konsumsi, produksi yang terus meningkat didapat estimasi kapasitas pabrik sebesar 75.000 ton/tahun. Untuk itu dibutuhkan bahan baku air laut yang digunakan sebesar 329.615,202 kg/jam. Lokasi pendirian pabrik direncanakan di Kecamatan Kalianget, Kabupaten Sumenep, Madura. Pabrik garam industri merupakan perusahaan yang berbadan hukum Perseroan Terbatas dengan sistem organisasi garis dan staff. Untuk dapat mendirikan pabrik garam industri dengan kapasitas 75.000 ton/tahun diperlukan total modal investasi sebesar Rp 289.134.495.235,- dan total biaya produksi sebesar Rp 128.420.085.269,- dengan estimasi hasil penjualan sebesar Rp. 318.330.000.000,- per tahun. Dengan estimasi umur pabrik 10 tahun, dapat diketahui internal rate of return (IRR) sebesar 39,3%, pay out time (POT) 5 tahun dan break even point (BEP) sebesar 23,24%.

Indonesia has the second longest coastline in the world and three quarters of Indonesia's territory is sea water. This potential can be utilized as one of the basic ingredients of salt commodity production. According to its function, one type of salt is industrial salt, which has a level of NaCl of at least 97% (dry basis). The use of industrial salt is intended as a raw material or additional material for the needs of other industries, such as the textile, pharmaceutical, and so on. The high need for industrial salt every year which is still imported from abroad is the background of the establishment of an industrial salt factory. The process of making industrial salt is divided into 3 process stages, namely pretreatment and refining of raw materials, cooking, and drying and control of industrial salt products. Pretreatment phase aims to eliminate impuritis in seawater which can interfere with the next process using the sedimentation process. The cooking phase aims to remove water and it is expected that the product will come out in the form of a wet crystal. The drying process is carried out to obtain industrial salt crystal products with 99.6% NaCl content. The plant is planned to operate in 2023. Based on data from imports, consumption, production which continues to increase, an estimated plant capacity of 75,000 tons / year is obtained. For this reason, seawater raw material is needed, which is 329,615,202 kg / hour. v The location of the plant construction is planned in Kalianget Subdistrict, Sumenep Regency, Madura. An industrial salt factory is a limited liability company with a line and staff organization system. To be able to set up an industrial salt factory with a capacity of 75,000 tons / year, a total investment capital of Rp 289,134,495,235 is required, and a total production cost of Rp 128,420,085,269, with an estimated sales proceeds of Rp. 318,330,000,000 per year. With an estimated factory life of 10 years, an internal rate of return (IRR) of 39.3%, pay-out time (POT) of 5 years and break even point (BEP) of 23.24% can be seen.
