Abstract

Indonesia adalah negara kepulauan dan memiliki laut yang luas dengan berbagai sumber daya hayati dan non-hayati yang sangat tinggi. Laut Indonesia menyimpan banyak potensi untuk dimanfaatkan, antara lain garam. Produksi garam rakyat di Indonesia cukup tinggi namun Indonesia masih mengimport garam industri dalam jumlah yang cukup besar. Berdasarkan permasalahan tingginya kebutuhan garam industri dan kurangnya produksi garam industri di Indonesia serta ketersediaan bahan baku berupa garam rakyat, maka hal tersebut membuka peluang untuk membangun pabrik garam industri dengan bahan baku garam rakyat dengan metode hidroekstraksi. Secara umum proses pencucian dengan metode hidroekstraksi dibagi menjadi 4 tahapan proses, yaitu tahap Pre-Treatment bahan baku, tahap pencucian dan pemisahan, tahap pengeringan dan pengemasan serta tahap pembuatan brine. Proses hidroekstraksi dipilih karena memiliki efisiensi operasi yang baik serta dapat menghemat biaya. Adapun garam industri yang dihasilkan dari proses tersebut memiliki kandungan NaCl sebesar 98,43% dengan kandungan NaCl awal pada garam rakyat sebesar 93,96%. Pabrik ini direncanakan akan beroperasi pada 2023 dengan kapasitas produksi garam industri sebesar 200.000 ton/tahun. Berdasarkan perhitungan untuk memenuhi kapasitas produksi diperlukan bahan baku berupa garam rayat sebanyak 237.600 ton/tahun dan brine sebanyak 396.600 ton/tahun. Untuk mendirikan pabrik ini diperlukan total modal investasi sebesar Rp.669.760.993.117,2; total biaya produksi Rp.267.422.221.494 dengan estimasi hasil penjualan per-tahun Rp.400.000.000.000. Dari perhitungan analisa ekonomi dapat diketahui Internal Rate of Return (IRR) sebesar 10,32%, Pay Out Time (POT) 6,28 tahun dan Breakeven Point (BEP) sebesar 71,42%. ===================================================================================================================== Indonesia is an archipelagic country and has a vast sea with a very high variety of biological and non-living resources. The Indonesian sea has a lot of potential to be exploited, including salt. People's salt production in Indonesia is quite high, but Indonesia still imports industrial salt in quite a large amount. Based on the problem of the high demand for industrial salt and the lack of industrial salt production in Indonesia as well as the availability of raw materials in the form of people's salt, this opens an opportunity to build an industrial salt factory using people's salt as raw material using the hydro-extraction method. In general, the washing process using the hydro-extraction method is divided into 4 process stages, namely the Pre-Treatment stage of raw materials, the washing and separation stage, the drying and packaging stage and the brine-making stage. The hydro-extraction process was chosen because it has good operating efficiency and can save costs. The industrial salt produced from this process has a NaCl content of 98.43% with the initial NaCl content in people's salt of 93.96%. This factory is planned to operate in 2023 with an industrial salt production capacity of 200,000 tons / year. Based on calculations to meet the production capacity, raw materials are required in the form of rayate salt as much as 237,600 tons / year and brine as much as 396,600 tons / year. To build this factory, a total investment capital of Rp. 669,760,993,117.2 is required; total production costs Rp. 267,422,221,494 with an estimated annual sales result of Rp. 400,000,000,000. From the calculation of the economic analysis, it can be seen that the Internal Rate of Return (IRR) is 10.32%, the Pay Out Time (POT) is 6.28 years and the Breakeven Point (BEP) is 71.42%.
