Gas hidrogen tidak dapat ditambang melainkan diproduksi, salah satunya produksi hidrogen dari limbah kaleng minuman aluminium direaksikan dengan air dan penambahan natrium hidroksida (NaOH) sebagai katalis. Reaksi tersebut menghasilkan gas hidrogen dan NaAl(OH)4. Dalam konteks ini, hidrogen dapat dikonversikan menjadi energi terbarukan, dimana energi tersebut ramah lingkungan dan emisi yang dihasilkan berupa uap air.Tujuan penelitian ini adalah mengembangkan teknik daur ulang limbah kaleng minuman aluminium seperti Pocari Sweat untuk menghasilkan gas hidrogen sebagai energi yang ramah lingkungan dan dapat diperbaharui. Penelitian ini dilakukan dengan mereaksikan aluminium dan air dengan katalis NaOH selama 43 menit pada suhu 300C. Dimana berat aluminium divariasikan (0.5 gr, 1 gr, 1.5 gr dan 2 gr), serta konsentrasi NaOH yang divariasikan (2N, 3N, 4N, 5N dan 6N). Dari hasil penelitian menunjukkan bahwa volume hidrogen terbesar pada berat aluminium 2 gram dengan konsentrasi NaOH 6N yaitu 1,081 liter. Untuk konversi aluminium tertinggi pada berat aluminium 0,5 gram dengan konsentrasi NaOH 6N yaitu 68,950 %, sedangkan yield hidrogen tertinggi pada berat aluminium yaitu 2 gram dengan konsentrasi NaOH 6N yaitu 3,539 %.References
