Abstract
Penelitian ini bertujuan mensintesis katalis Ni/γ-Al₂O₃, mengevaluasi pengaruh variasi nikel terhadap karakteristik katalis, serta menentukan kondisi operasi optimum pada produksi SAF melalui reaksi deoksigenasi minyak jarak menggunakan Desain Eksperimen Taguchi. Katalis Ni/γ-Al₂O₃ disintesis dengan metode impregnasi basah dengan variasi loading nikel sebesar 2,5; 5; dan 10 wt%. Karakterisasi katalis dilakukan menggunakan X-Ray Diffraction (XRD), Fourier Transform Infrared Spectroscopy (FTIR), dan Scanning Electron Microscopy–Energy Dispersive X-ray (SEM-EDX). Produk hasil deoksigenasi dianalisis menggunakan Gas Chromatography–Mass Spectrometry (GC-MS). Optimasi proses dilakukan menggunakan desain eksperimen Taguchi L9 dengan tiga faktor, yaitu loading nikel, waktu reaksi, dan massa katalis. Hasil karakterisasi menunjukkan bahwa peningkatan loading nikel meningkatkan kristalinitas, ukuran kristal, serta menghasilkan morfologi partikel yang lebih teratur. Analisis Taguchi menunjukkan bahwa kondisi optimum reaksi diperoleh pada loading nikel 10 wt%, waktu reaksi 1 jam, dan massa katalis 10 g. Analisis ANOVA menunjukkan bahwa loading nikel merupakan faktor yang paling berpengaruh terhadap konversi minyak jarak dengan kontribusi sebesar 53%, diikuti waktu reaksi sebesar 23% dan massa katalis sebesar 11%.

Sustainable Aviation Fuel (SAF) is an environmentally friendly aviation fuel with the potential to significantly reduce greenhouse gas emissions. SAF can be produced from castor oil (Ricinus communis L.) through a deoxygenation reaction. This study aimed to synthesize Ni/γ-Al₂O₃ catalyst, evaluate the effect of nickel loading variation on catalyst characteristics, and determine the optimum operating conditions for SAF production through the deoxygenation of castor oil using Taguchi Experimental Design. The Ni/γ-Al₂O₃ catalyst was synthesized by the wet impregnation method with nickel loadings of 2.5, 5, and 10 wt%. Catalyst characterization was carried out using X-Ray Diffraction (XRD), Fourier Transform Infrared Spectroscopy (FTIR), and Scanning Electron Microscopy–Energy Dispersive X-ray (SEM-EDX). The deoxygenation products were analyzed using Gas Chromatography–Mass Spectrometry (GC-MS). Process optimization was performed using a Taguchi L9 experimental design with three factors, namely nickel loading, reaction time, and catalyst mass. The characterization results showed that increasing nickel loading improved crystallinity, crystal size, and produced a more regular particle morphology. Taguchi analysis indicated that the optimum reaction conditions were obtained at 10 wt% nickel loading, 1 hour reaction time, and 10 g catalyst mass. ANOVA results showed that nickel loading was the most influential factor on castor oil conversion, contributing 53%, followed by reaction time at 23% and catalyst mass at 11%.
