[ABSTRAK
Tesis ini meneliti mengenai pengaruh pengurangan mineral pengotor pada bentonit menggunakan alat hidrosiklon dan modifikasi pertukaran kation dengan penambahan dosis surfaktan terhadap basal spasi organobentonit yang dihasilkan serta terhadap sifat-sifat dari nanokomposit karet alam/organobentonit. Nanokomposit karet alam/organobentonit dibuat dengan teknik pelelehan
kompon. Hasil penelitian menunjukkan proses reduksi mineral pengotor pada bentonit telah mampu mengurangi kandungan senyawa pengotor, seperti Fe2O3, CaO, dan K2O. Sementara itu, peningkatan dosis surfaktan pada bentonit dapat meningkatkan basal spasi pada organobentonit. Organobentonit rendah mineral pengotor ini mampu menghasilkan nanokomposit dengan sifat mekanik yang lebih baik dari nanokomposit berbahan pengisi bentonit alam.;

ABSTRACT
This thesis are to studies the effect of the reduction of mineral impurities in the bentonite using hydrocyclone and the effect of cation exchange modification with the addition of surfactant dosage on the basal spacing of organobentonit and the
properties of natural rubber/organobentonite nanocomposites Natural rubber/organobentonite nanocomposites made by melting compound technique.
The results showed the reduction process of mineral impurities in the bentonite has been able to reduce the content of impurities, such as Fe2O3, CaO, and K2O.
Meanwhile, an increase in the dose of surfactant on bentonite may increase the basal spacing of organobentonite. Low mineral impurities organobentonite is capable of producing nanocomposite with better mechanical properties than nanocomposite filled pristine bentonite.;This thesis are to studies the effect of the reduction of mineral impurities in the bentonite using hydrocyclone and the effect of cation exchange modification with the addition of surfactant dosage on the basal spacing of organobentonit and the
