Nira sorgum manis saat ini banyak digunakan untuk bahan baku bioetanol dan berpotensi untuk diolah menjadi gula cair. Namun, partikel pengotor dari proses ekstraksi masih menjadi permasalahan baik pada proses fermentasi maupun evaporasi. Penelitian ini bertujuan untuk menentukan kondisi optimal proses penjernihan nira sorgum melalui proses sentrifugasi dengan menganalisis pengaruh kecepatan putar (300-700 RPM) dan lama sentrifugasi (45-75 menit) pada parameter turbiditas dan total soluble solid (TSS) menggunakan metode Response Surface Methodology (RSM). Hasil penelitian menunjukkan bahwa kecepatan putar dan lama sentrifugasi memiliki pengaruh signifikan pada nilai turbiditas dan TSS. Adapun kondisi optimum didapatkan pada kecepatan putar 500 RPM selama 53,49 menit dengan nilai turbiditas 2,02 NTU dan TPT 17,93 0Brix. Hasil ini diharapkan mampu memberikan informasi kondisi terbaik pada proses penjernihan nira sorgum menggunakan sentrifugasi.
