Penelitian ini bertujuan untuk menganalisis kinetika reaksi dan energi aktivasi pada hidrolisis selulosa dari pelepah pisang barangan. Proses hidrolisis dilakukan menggunakan asam sulfat (H₂SO₄) sebagai katalis dengan variasi suhu dan waktu. Kadar glukosa hasil hidrolisis ditentukan dengan metode fenol-asam sulfat menggunakan spektrofotometer UV-Vis pada panjang gelombang 480 nm. Hasil menunjukkan peningkatan konsentrasi glukosa seiring kenaikan suhu dan waktu reaksi. Hasil analisis kinetika reaksi hidrolisis selulosa dengan katalis asam sulfat menunjukkan reaksi orde pertama dimana R² = 0,981 diperoleh dari hubungan antara ln[A] vs t dan energi aktivasi 4,598 kJ/mol.

Kata Kunci: Pelepah pisang, hidrolisis selulosa, kinetika reaksi, energi aktivasi, asam sulfat.

This study aims to analyze the reaction kinetics and activation energy in cellulose hydrolysis from banana barangan fronds. The hydrolysis process was carried out using sulfuric acid (H₂SO₄) as a catalyst with variations in temperature and time. The glucose content of the hydrolysis was determined by the phenol-sulfuric acid method using a UV-Vis spectrophotometer at a wavelength of 480 nm. The results showed an increase in glucose concentration as the reaction temperature and time increased. The analysis of cellulose hydrolysis reaction kinetics with sulfuric acid catalyst showed a first-order reaction where R² = 0.981 was obtained from the relationship between ln[A] vs t and activation energy of 4.598 kJ/mol. Keywords: Banana leaf, cellulose hydrolysis, reaction kinetics, activation energy, sulfuric acid.
