Abstract
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 83,26%.
Produk korosi akibat lingkungan air laut maupun air laut + lumpur
hampir tidak ada perbedaan yaitu α-Fe2O3, γ-Fe2O3 dan Fe3O4.

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 83,26%. The products of corrosion due to sea
water nor sea water + mud almost no difference, that is α-Fe2O3, γ-
Fe2O3 and Fe3O4.
