Abstract
Sektor penyimpanan energi saat ini berkembang cukup pesat, salah satunya terkait performa kapasitansi elektroda baterai.. Indonesia merupakan salah satu negara dengan penghasil padi terbanyak di dunia, setelah Cina dan India. Sekam padi dapat diekstraksi menjadi silika dengan metode sol-gel. Dan menjadi karbon dengan metode hidrotermal karbonisasi. Metode Hydrothermal Carbonization (HTC) dipilih karena ramah lingkungan dan ekonomis. Silika dan karbon yang didapatkan dari sekam padi kemudian dibentuk menjadi komposit nanopartikel silika-karbon. Pada hidrotermal karbonisasi, variabel yang divariasikan adalah waktunya, yaitu 2, 4, 6, 8, 10, dan 12 jam masing-masing pada temperatur 250oC. Setelah itu, sampel diuji XRD, FTIR, SEM-EDX untuk mengetahui karakterisasinya, serta diuji CV untuk mengetahui kapasitansi spesifiknya. Didapatkan bahwa kapasitansi spesifik tertinggi berturut-turut dimiliki oleh waktu hidrotermal 12 jam (13,873 F/g), 8 jam (13,336 F/g), 6 jam (11,693 F/g), 4 jam (4,601 F/g), dan 2 jam (0,672 F/g) dimana seiring dengan bertambahnya waktu karbonisasi hidrotermal, bertambah pula kapasitansi spesifiknya.

The energy storage sector is developing quite rapidly, one of which is related to battery capacitance performance.. Indonesia is one of the countries with the most rice producers in the world, after China and India. Rice husks can be extracted into silica by the sol-gel method and become carbon by hydrothermal carbonization method. The Hydrothermal Carbonization (HTC) method was chosen because it is environmentally friendly and economical. Silica and carbon obtained from rice husks are then formed into silica-carbon nanoparticle composites. In hydrothermal carbonization, the time is varied, which are 2, 4, 6, 8, 10, and 12 hours each at a temperature of 250oC. Then samples were tested by XRD, FTIR, SEM-EDX to determine their characteristics and CV for their specific capacitance. It was found that the highest specific capacitance was owned by the hydrothermal time 12 hours (13,873 F / g), 8 hours (13,336 F / g), 6 hours (11,693 F / g), 4 hours (4,601 F / g), and 2 hours (0.672 F / g).
