ABSTRAK

Magnesium oksida merupakan suatu bahan baku yang banyak digunakan di industri namun produksi MgO di Indonesia sangat rendah. Badan Pusat Statistika Surabaya menunjukkan adanya data MgO di Indonesia bahwa angka impor lebih tinggi daripada angka ekspor dan produksi. Berdasarkan data tersebut dapat disimpulkan bahwa Indonesia masih belum mampu memenuhi kebutuhan MgO dalam negeri maka direncanakan untuk mendirikan pabrik penghasil MgO. Pabrik menggunakan bahan baku mineral dolomit yang ketersediaannya sangat berlimpah di Indonesia dengan menggunakan proses digesti. Proses pembuatan MgO yang pertama adalah proses Digesti dimana dolomit dilarutkan pada larutan HCl 15. Tahap kedua adalah proses pengendapan dimana MgOH2 yang dihasilkan kemudian diendapkan menggunakan prinsip gravimetri padatan dipisahkan dari larutan suspensi. Tahap selanjutnya adalah proses penyaringan dimana endapan MgOH2 disaring menggunakan Rotary Drum Vacuum Filter untuk menghilangkan kandungan air di dalam endapan. Dan tahap terakhir adalah proses dekomposisi termal dimana proses ini dilakukan pada temperatur sekitar 330oC selama 1 jam sehingga menghasilkan MgO yang memiliki kemurnian hingga 91. Pabrik MgO berlokasi di Gresik kecamatan Manyar dan lokasi penyediaan bahan baku mineral dolomit di pulau Madura. Pabrik ini direncanakan bekerja 300 hari per tahun dengan 24 jam kerja per hari. Dengan perencanaan pelaksanaan pada tahun 2015 dengan mencapai kapasitas 130430 ton tahun.


ABSTRACT

Magnesium oxide is a raw material widely used in industry. However production of MgO in Indonesia is very low. This is shown by the data from Surabaya Statistic Center BPS that the import number is greater than export and the production number. It can be concluded that Indonesia is still not able to meet the domestic needs of MgO.For fulfilling the MgO needs that continualy increasing it has been planed to building a factory that produce MgO with dolomites mineral as an abundant material available in Indonesia. The processing of MgO from dolomite in the first process is digestion where dolomite are dissolved in 15 HCl solution. The second process is the deposition in which the MgOH2 is resulted then deposited using a gravimetric principle solids separated from the aqueous suspension. The next process is screening which precipitated of MgOH2 was filtered using a Rotary Drum Vacuum Filter to remove the water content in the sediment. And the last process is the thermal decomposition this process is carried out at a temperature of about 330oC for 1 hour after that is all the MgO was producted and the purity is up to 91. The location of MgO factorys is on Gresik Manyar districts and the location which providing the raw materials mineral dolomite on the Madura islands. This factory is programmed to work for 300 days in every year with 24h workhour in each day. With the implementation of the plan in 2015 it will be achieving a production capacity of 130430 tonsyear.
