Abstrak

Penelitian ini bertujuan untuk menganalisis kandungan Free Fatty Acid (FFA) dan viskositas pada limbah minyak goreng (Waste Cooking Oil/WCO) yang dihasilkan oleh UMKM di Kota Malang sebagai upaya pengendalian mutu bahan baku biodiesel. Pengujian dilakukan terhadap 60 sampel minyak dengan metode titrasi alkalimetri untuk FFA dan viskometer Brookfield untuk viskositas. Hasil analisis menunjukkan bahwa rata-rata kadar FFA sebesar 1,38% dengan kisaran 0,07–7,46%, sedangkan viskositas rata-rata sebesar 31,28 cP dengan kisaran 22,75–42,13 cP. Sebagian besar sampel memenuhi batas aman (<2%) untuk proses transesterifikasi langsung, sementara sekitar 25% sampel memerlukan pra-esterifikasi. Analisis korelasi Pearson menunjukkan hubungan negatif lemah namun signifikan (r = -0,2898; p < 0,05), menandakan FFA dan viskositas perlu dikendalikan secara independen. Hasil ini menegaskan pentingnya penerapan sistem pengendalian mutu sederhana di tingkat UMKM sebagai langkah awal menuju produksi biodiesel berkelanjutan.
