Abstract
Sustainable Aviation Fuel (SAF) merupakan bahan bakar penerbangan yang berasal dari sumber terbarukan seperti minyak nabati. Secara kimia, SAF memiliki karakteristik yang sangat mirip dengan bahan bakar fosil konvensional. Penelitian ini bertujuan untuk memproduksi SAF dari minyak nyamplung (Calophyllum inophyllum) melalui reaksi deoksigenasi. Proses ini menggunakan katalis Fe/γ-Al₂O₃ dengan variasi loading besi sebesar 2, 4, dan 8 wt%. Katalis disintesis menggunakan metode impregnasi basah dan dikarakterisasi menggunakan X-Ray Diffraction (XRD) dan Fourier Transform Infrared (FTIR). Hasil XRD menunjukkan dua fasa dominan, yaitu α-Fe pada 2θ ≈ 45,5° serta γ-Al₂O₃ pada 2θ ≈ 37°, 45,7°, dan 67°. Intensitas puncak α-Fe meningkat seiring dengan bertambahnya loading logam besi, yang mengindikasikan terbentuknya partikel besi yang lebih besar. Hasil FTIR menunjukkan pita Al O pada 1641, 800, dan 570 cm⁻¹. Hal ini menandakan bahwa fasa logam besi berhasil terbentuk pada permukaan pendukung alumina. Uji aktivitas katalis dilakukan pada reaksi deoksigenasi minyak nyamplung pada suhu 300°C, tekanan H₂ 5 bar, selama 2 jam. Produk reaksi dianalisis menggunakan GC-MS untuk menentukan persentase konversi. Hasil uji menunjukkan peningkatan konversi minyak nyamplung menjadi SAF dari 22% menjadi 61,62% seiring dengan kenaikan loading Fe dari 2 wt% menjadi 8 wt%. Katalis berbasis besi berpotensi diaplikasikan pada produksi SAF dari minyak nyamplung.

Sustainable Aviation Fuel (SAF) is an aviation fuel derived from renewable sources such as vegetable oil. Chemically, SAF has very similar characteristics to conventional fossil fuels. This study aims to produce SAF from nyamplung oil (Calophyllum inophyllum) through a deoxygenation reaction. This process uses a Fe/γ-Al₂O₃ catalyst with iron loading variations of 2, 4, and 8 wt%. The catalyst was synthesized using a wet impregnation method and characterized using X-Ray Diffraction (XRD) and Fourier Transform Infrared (FTIR). The XRD results show two dominant phases, namely α-Fe at 2θ ≈ 45.5° and γ-Al₂O₃ at 2θ ≈ 37°, 45.7°, and 67°. The intensity of the α-Fe peak increased with increasing iron metal loading, indicating the formation of larger iron particles. FTIR results showed Al-O bands at 1641, 800, and 570 cm⁻¹. This indicates that the iron metal phase was successfully formed on the surface of the alumina support. The catalyst activity test was carried out on the deoxygenation reaction of nyamplung oil at a temperature of 300°C, H₂ pressure of 5 bar, for 2 hours. The reaction products were analyzed using GC-MS to determine the percentage of conversion. The test results showed an increase in the conversion of nyamplung oil to SAF from 22% to 61.62% along with the increase in Fe loading from 2 wt% to 8 wt%. Iron-based catalysts have the potential to be applied to the production of SAF from nyamplung oil.
