Abstract

Abu sekam padi (Rice Hush Ash, RHA) apabila dikalsinasi pada suhu tinggi (500-600 ⁰C) menghasilkan senyawa silikat yang dapat dimanfaatkan untuk beragai proses kimia. Senyawa silikat merupakan senyawa terbesar penyusun abu sekam padi yaitu mencapai ±96,6%. Penelitian pendahuluan menunjukkan bahwa silikat yang dihasilkan dari sekam padi s.ebesar 15% dari berat sekam padi yang dikalsinasi. Untuk mengetahui struktur silikat yang dihasilkan maka dilakukan analisa dengan menggunakan X-Ray Diffraction (XRD) dengan cara membandingkan diffractogram dari silikat murni . silikat yang dihasilkan kemudian diuji kemampuan daya perengkaha dan aromatisasinya sebagai katalis dalam reaksi heksana dengan menggunakan quartz tube reactor pada suhu 200-300 ⁰C. Dari hasil XRD dapat disimpulkan bahwa abu sekam padi bias digunakan sebagai sumber silikat murni. Uji laboratorium menunjukkan bahwa silikat yang dihasilkan dari abu sekam padi mempunyai potensi sebagai katalis untuk reaksi perengkahan dan aromatisasi.
