Abstract
Material penghantar listrik dari bahan organik seperti sekam padi dapat digunakan sebagai pengganti bahan kimia. Sekam padi merupakan sumber karbon yang mana merupakan material penghantar listrik yang baik. Selain itu, sekam padi juga mengandung silika dengan struktur berpori. Pada penelitian ini, dilakukan sintesis silika dan karbon dari sekam padi. Silika diekstrak menggunakan metode sol gel dan karbon disintesis menggunakan metode karbonisasi hidrotermal. Temperatur karbonisasi hidrotermal divariasikan dari 150°C-350°C. Selanjutnya silika dan karbon diproses menjadi komposit silika-karbon. Penelitian ini bertujuan untuk menganalisis pengaruh temperatur karbonisasi hidrotermal terhadap karakteristik pori dan kapasitansi komposit silika karbon agar dapat digunakan sebagai material penyimpan energi. Hasil uji XRD dan FTIR menunjukkan bahwa silika dan karbon berhasil disintesis. Hasil uji SEM menunjukkan bahwa sampel memiliki struktur berpori yang tidak teratur. Dari hasil uji CV, nilai kapasitansi tertinggi terdapat pada sampel SiO2-C-350 dengan nilai sebesar 38.652 F/g. Material ini belum dapat diaplikasikan sebagai material penyimpan energi karena nilai kapasitansinya masih kecil.

Electrically conducting materials from organic materials such as rice husks can be used instead of chemicals. Rice husk is a source of carbon which is a good conductor of electricity. In addition, rice husks also contain silica with a porous structure. In this research, silica and carbon synthesis from rice husk was carried out. Silica is extracted using the sol gel method and carbon is synthesized using the hydrothermal carbonization method. Hydrothermal carbonization temperature varies from 150 ° C-350 ° C. Furthermore, silica and carbon are processed into silica-carbon composites. This study aims to analyze the effect of hydrothermal carbonization temperature on pore characteristics and carbon silica composite capacitance so that it can be used as an energy storage material. XRD and FTIR test results showed that silica and carbon were successfully synthesized. SEM test results show that the sample has an irregular porous structure. From the CV test results, the highest capacitance value is found in the SiO2-C-350 sample with a value of 38,652 F / g. This material cannot be applied as an energy storage material because the capacitance value is still small.
