Abstract

The increasing demand for energy necessitates the exploration of alternative energy sources such as hydrogen due to its high energy content and minimal environmental impact. Aluminum has been extensively researched for its potential to produce hydrogen efficiently. The reaction between aluminum and water is particularly promising due to the high energy density of aluminum. This final project investigates the impact of ultrasonic waves and catalysts on hydrogen production from the reaction of AA1235 aluminum with water. This research explores how temperature, catalyst (specifically NaOH and NaAlO₂), and ultrasonic waves influence the reaction kinetics and hydrogen production efficiency. The method performed in this research is the reaction of aluminum AA1235 and water to produce hydrogen gas. Four catalyst variations and three temperature variations were used for each catalyst. In this experiment, ultrasonic waves were also added to the reaction. The findings show that ultrasonic waves significantly increase hydrogen production, making the process more efficient. It is seen from the results obtained, that ultrasonic waves accelerate hydrogen production and increase efficiency. NaOH and NaAlO₂ catalysts produced high volumes of hydrogen, especially at 30°C with the combination of 0.5 M NaOH + 1.5 M NaAlO₂ achieving yield until 94.64%. This study concludes that the use of ultrasonic waves and appropriate catalysts can increase hydrogen production from the reaction of aluminum and water.

Meningkatnya permintaan akan energi mengharuskan eksplorasi sumber energi alternatif seperti hidrogen karena kandungan energinya yang tinggi dan dampak lingkungan yang minimal. Aluminium telah diteliti secara ekstensif karena potensinya untuk menghasilkan hidrogen secara efisien. Reaksi antara aluminium dan air sangat menjanjikan karena kepadatan energi yang tinggi dari aluminium. Tugas akhir ini menyelidiki dampak gelombang ultrasonik dan katalis terhadap produksi hidrogen dari reaksi aluminium AA1235 dengan air. Penelitian ini mengeksplorasi bagaimana suhu, katalis (khususnya NaOH dan NaAlO2), dan gelombang ultrasonik mempengaruhi kinetika reaksi dan efisiensi produksi hidrogen. Metode yang dilakukan dalam penelitian ini adalah reaksi aluminium AA1235 dan air untuk menghasilkan gas hidrogen. Empat variasi katalis dan tiga variasi temperatur digunakan untuk setiap katalis. Dalam percobaan ini, gelombang ultrasonik juga ditambahkan ke dalam reaksi. Temuan menunjukkan bahwa gelombang ultrasonik secara signifikan meningkatkan produksi hidrogen, membuat proses menjadi lebih efisien. Dilihat dari hasil yang diperoleh, bahwa gelombang ultrasonik mempercepat produksi hidrogen dan meningkatkan efisiensi. Katalis NaOH dan NaAlO₂ menghasilkan hidrogen dalam jumlah besar, terutama pada suhu 30°C dengan kombinasi 0,5 M NaOH + 1,5 M NaAlO₂ yang mencapai yield hingga 94,64%. Penelitian ini menyimpulkan bahwa penggunaan gelombang ultrasonik dan katalis yang tepat dapat meningkatkan produksi hidrogen dari reaksi aluminium dan air.
