Abstract: Proses pengolahan Tandan Buah Segar (TBS) menjadi Crude Palm Oil (CPO) dipengaruhi oleh variabel proses seperti suhu, tekanan, dan waktu perebusan yang menentukan kualitas serta rendemen minyak. Penelitian ini bertujuan untuk mengevaluasi pengaruh waktu perebusan, perbedaan suhu, dan tekanan uap terhadap rendemen CPO dan kadar asam lemak bebas (Free Fatty Acid/FFA), menilai performa model optimasi, serta menentukan kombinasi parameter proses terbaik.Analisis dilakukan menggunakan regresi linier dan metode Taguchi dengan tiga faktor utama, yaitu lama waktu perebusan, Δ suhu perebusan, dan Δ tekanan uap perebusan. Hasil penelitian menunjukkan bahwa waktu perebusan berpengaruh signifikan terhadap rendemen CPO dan kadar FFA dengan P-value masing-masing 0,000 dan 0,001, sedangkan Δ suhu berpengaruh signifikan hanya terhadap rendemen (P-value 0,001). Δ tekanan uap tidak menunjukkan pengaruh signifikan (P-value > 0,05). Model optimasi memiliki performa sangat baik dengan R² sebesar 99,15% untuk rendemen CPO dan 92,80% untuk kadar FFA.Kombinasi optimal diperoleh pada lama perebusan 80 menit, Δ suhu 40,1°C, dan Δ tekanan uap 1,58 bar, menghasilkan rendemen CPO 42,17% dan FFA 2,40%. Kondisi ini dinilai paling efisien untuk meningkatkan hasil dan kualitas CPO. The processing of Fresh Fruit Bunches (FFB) into Crude Palm Oil (CPO) is influenced by process variables such as temperature, pressure, and boiling time, which determine the oil’s yield and quality. This study aims to evaluate the effects of boiling time, temperature difference, and steam pressure on CPO yield and Free Fatty Acid (FFA) levels, assess the performance of the optimization model, and determine the optimal combination of process parameters. The analysis was carried out using linear regression and the Taguchi method with three main factors: boiling time, temperature difference (ΔT), and steam pressure difference (ΔP). The results showed that boiling time had a significant effect on both CPO yield and FFA levels, with P-values of 0.000 and 0.001, respectively, while ΔT significantly affected only CPO yield (P-value 0.001). ΔP showed no significant effect (P-value > 0.05). The optimization model demonstrated excellent performance, with R² values of 99.15% for CPO yield and 92.80% for FFA.The optimal combination was obtained at 80 minutes of boiling time, ΔT of 40.1°C, and ΔP of 1.58 bar, resulting in a CPO yield of 42.17% and an FFA level of 2.40%. These conditions were found to be the most efficient for improving CPO yield and quality.
