<note>Limbah minyak pelumas bekas merupakan salah satu limbah B3 yang berbahaya bagi lingkungan dan kesehatan manusia. Pirolisis katalitik menjadi metode yang potensial untuk mengonversi limbah ini menjadi bahan bakar alternatif yang ramah lingkungan. Penelitian ini mengenalkan pengolahan limbah dengan sintesis nanokatalis FeNi/TiO2 dengan metode mikroemulsi menggunakan ekstrak biji anggur sebagai pereduksi alami dan efektivitasnya dalam pirolisis limbah minyak pelumas bekas. Analisis dilakukan terhadap Yield minyak pirolisis, densitas, nilai kalor, dan viskositas produk bahan bakar yang dihasilkan. Hasil rata-rata yang diperoleh sebelum dilakukan optimasi adalah Yield oil 75,36%, densitas 781 kg/m3, viskositas 1,4953 cP dan nilai kalor 11.112 cal/g. Setelah dilakukannya optimasi hasil cenderung meningkat yaitu Yield oil 76,07%, densitas 829,4 kg/m3, viskositas 2,2715 cP dan nilai kalor 11.016 cal/g. Analisis GC-MS mengonfirmasi bahwa hidrokarbon dalam minyak pirolisis mendekati karakteristik bahan bakar pertamina dex. Hasil penelitian menunjukkan bahwa penggunaan nanokatalis FeNi/TiO₂ dalam pengolahan limbah oli bekas memiliki potensi besar dalam mengonversi limbah menjadi energi berkelanjutan.

Used lubricating oil waste is one of the hazardous B3 wastes that pose a threat to both the environment and human health. Catalytic pyrolysis is a potential method for converting this waste into an environmentally friendly alternative fuel. This study introduces a waste treatment approach using FeNi/TiO₂ nanocatalyst synthesis via the microemulsion method, utilizing grape seed extract as a natural reducing agent, and evaluates its effectiveness in the pyrolysis of used lubricating oil waste. The analysis was conducted on the pyrolysis oil yield, density, calorific value, and viscosity of the produced fuel. The average results obtained before optimization were an oil yield of 75,36%, a density of 781 kg/m³, a viscosity of 1,4953 cP, and a calorific value of 11.112 cal/g. After optimization, the results tended to improve, with an oil yield of 76.07%, a density of 829,4 kg/m³, a viscosity of 2,2715 cP, and a calorific value of 11.016 cal/g. GC-MS analysis confirmed that the hydrocarbons in the pyrolysis oil closely resemble the characteristics of Pertamina Dex fuel. The findings indicate that the use of FeNi/TiO₂ nanocatalysts in waste oil treatment holds great potential for converting waste into sustainable energy.</note>
