Abstract
Dalam penelitian ini, dilakukan sintesis dan karakterisasi karbon aktif yang berasal dari tandan kosong kelapa sawit (TKKS) untuk digunakan sebagai elektroda baterai. Penelitian ini melibatkan variasi konsentrasi KOH dan penambahan silika (SiO2) sebagai komposit doping. Proses diawali dengan aktivasi kimia menggunakan berbagai konsentrasi KOH, diikuti dengan aktivasi fisika dan doping silika. Karakterisasi karbon aktif TKKS pengujian morfologi permukaan, luas permukaan, struktur kristal, dan kapasitansi spesifik. Selain itu, penelitian ini meliputi perancangan, perakitan, dan pengukuran potensial listrik prototipe baterai. Konsentrasi KOH aktivasi optimal sebesar 5 M menghasilkan luas permukaan tertinggi sebesar 352,58 m²g-1, kapasitansi spesifik sebesar 247,14 mAh/g, dan kestabilan tegangan sebesar 1,38 V untuk karbon aktif. Setelah didoping dengan silika, komposit SiO₂-G/C 5 M menunjukkan luas permukaan yang jauh lebih tinggi yaitu 767,32 m²g-1, kapasitansi spesifik 284,32 mAh/g, dan voltase 1,55V. Temuan ini menunjukkan peningkatan yang nyata dalam sifat elektrokimia material. Secara keseluruhan, hasil ini menghasilkan potensi karbon aktif yang berasal dari TKKS dengan doping silika sebagai elektroda baterai berkinerja tinggi untuk penyimpanan energi, khususnya pada baterai pouch cell.
