Abstract
Sustainable Aviation Fuel (SAF) merupakan bahan bakar alternatif ramah lingkungan yang dapat di produksi dari minyak nabati melalui reaksi deoksigenasi. Penelitian ini bertujuan untuk mengoptimalkan konversi minyak biji jarak menjadi SAF dengan menggunakan katalis Co/γ-Al2O3 yang dirancang melalui Desain Eksperimen Taguchi. Katalis disintesis melalui metode impregnasi basah dengan variasi loading kobalt sebesar 2,5; 5 dan 10 wt%. Karakteristik katalis dianalisis menggunakan Fourier Transform Infra-Red (FTIR) untuk identifikasi gugus fungsi, Scanning Electron Microscope-energy Dispersive X-Ray (SEM) untuk analisis morfologi permukaan, serta X- Ray Diffraction (XRD) untuk analisi fasa kristal. Konversi minyak biji jarak menjadi SAF dievaluasi berdasarkan tiga faktor yaitu loading kobalt pada katalis Co/γ-Al2O3 (2,5; 5; dan 10 wt%), waktu reaksi (1, 3, dan 5 jam), dan massa katalis (2,5; 5; dan 10 gram). Masing-masing faktor terdiri dari 3 level yang sesuai dengan matriks orthogonal array L9. Hasil reaksi dianalisis menggunakan GC-MS untuk menentukan persentase konversi. Hasil karakterisasi menunjukkan keberadaan fase kobalt pada pendukung γ-Al2O3 dan distribusi kobalt yang merata pada permukaan katalis. Desain Eksperimen Taguchi menunjukkan bahwa kondisi optimum diperoleh pada loading katalis 5 wt%, waktu reaksi 5 jam, dan massa katalis 2,5gram. Pengaruh masing-masing faktor ditunjukkan dengan angka persentase kontribusi yaitu 43,97% untuk loading kobalt, 25,19% untuk waktu reaksi dan 30,83% untuk massa katalis.

Sustainable Aviation Fuel (SAF) is an environmentally friendly alternative fuel that can be produced from vegetable oils through deoxygenation reactions. This study aims to optimize the conversion of castor seed oil into SAF using a Co/γ-Al2O3 catalyst designed through Taguchi Experimental Design. The catalyst was synthesized using the wet impregnation method with cobalt loading variations of 2.5, 5, and 10 wt%. The catalyst characteristics were analyzed using Fourier Transform Infra-Red (FTIR) for functional group identification, Scanning Electron Microscope-energy Dispersive X-Ray (SEM-EDX) for surface morphology analysis, and X-Ray Diffraction (XRD) for crystal phase analysis. The conversion of castor seed oil into SAF was evaluated based on three factors: cobalt loading on the Co/γ-Al2O3 catalyst (2,5; 5; and 10 wt%), reaction time (1, 3, and 5 hours), and catalyst mass (2,5; 5; and 10 gram). Each factor consisted of 3 levels according to the L9 orthogonal array matrix. Reaction products were analyzed by GC‑MS to determine the conversion percentages. Characterization results confirmed the presence of cobalt phases on the γ‑Al₂O₃ support and a uniform cobalt distribution on the catalyst surface. Taguchi analysis identified the optimum conditions as cobalt loadings of 5 wt%, a reaction time of 5 h, and a catalyst mass of 2,5 g. The contribution of each factor to the response was 43,97% for cobalt loading, and 25,19% each for reaction time and 30,83% for catalyst mass.
