ABSTRAK

Lumpur lapindo sudah terjadi sejak tahun 2006 dengan semburan mencapai 35 m3 perharinya sehingga lumpur lapindo banyak menggenangi perumahan warga dan banyak merugikan warga disekitar pusat semburan lumpur. Setelah dilakukan penelitian ternyata lumpur lapindo mempunyai banyak kandungan silika dimana silika ini bisa dibuat menjadi inhibitor natrium silikat Na2SiO3 dengan mencampurkan lumpur lapindo dengan natrium hidroksida NaOH. Dalam penelitian ini metode ekstraksi yang digunakan ada 2. Metode pertama mengacu pada penelitian Aditya 2014 dan metode kedua mengacu pada penelitian Mustofa 2013. Pengujian korosi dilakukan dengan menggunakan 3 inhibitor yaitu inhibitor komersil inhibitor sintesis 1 dan inhibitor sintesis 2 yang diuji pada 2 larutan uji yaitu larutan air laut dan larutan air laut lumpur. Sebagai inhibitor natrium silikat hasil sintesis 1 dan sintesis 2 bekerja cukup efektif pada lingkungan air laut lumpur dibandingkan inhibitor komersil akan tetapi pada lingkungan air laut inhibitor komersil memiliki efisiensi yang hampir sama dengan inhibitor hasil sintesis. Penambahan inhibitor 10 ml pada media uji air laut lumpur natrium silikat hasil sintesis 1 memberikan perlindungan terbaik dengan efisiensi sebesar 8326. Produk korosi akibat lingkungan air laut maupun air laut lumpur hampir tidak ada perbedaan yaitu 945-Fe2O3 947-Fe2O3 dan Fe3O4.


ABSTRACT

Lapindo mud has been taking place since 2006 wich is bursting of 35 m3 per day. The mudflow has destroyed the populated housing. According to some researches lapido mud contains a lot of silica which is potential for being used as natrium silicate Na2SiO3 through mixing the mud with natrium hidroxide NaOH. This reseach used two methods. the first one to refers to Aditya 2014 and the latter is according to Mustofa 2013. Corrosion testing is performed using 3 inhibitor that is commercial inhibitor synthesis inhibitor 1 synthesis inhibitor 2 which is tested on two test solution it is sea water solution and sea-water mud solution . As an inhibitor of the natrium silicate synthesis results synthesis 1 and synthesis 2 work effectively on the sea water mud than commercial inhibitor but on environment of sea water commercial inhibitor has similar efficiency with synthesis results inhibitor. The addition of 10 ml inhibitor on media test ocean water mud synthesis results natrium silicate 1 provides the best protection with the efficiency of 8326. The products of corrosion due to sea water nor sea water mud almost no difference that is 945-Fe2O3 947- Fe2O3 and Fe3O4.
