Separation of Amino acid from Liquid waste of Oil palm Factory with Ion Exchange Chromatography Research on Separation of Amino Acid Liquid Waste mills with Ion Exchange Chromatography was carried out from October to November 2015. The results of hydrolysis of 6 N HCl results showed that the highest absorbance reading was obtained at a concentration of eluent of 0,2 and 0,6 M NaCl, while the results of the protease enzyme hydrolysis the highest absorbance reading at NaCl eluent 0,2 and 1 M. There was no significant difference in the results of separation by ion exchange chromatography, showed that the concentration of NaCl eluent is not very influential, so for subsequent analysis used only one concentration of the eluent. Results of linear regression obtained was equal to 0,9946, these results indicate that the series standard amino acid lysine has a value that is linear as it approaches 1. The amino acid levels obtained on the sample results LCPKS hydrolysis with 6 N HCl which was about 0 to 8.82 ppm and samples of the protease enzyme hydrolysis of about 0 to 4.31 ppm. Amino acid levels obtained were still far from the expected.Keywords: Amino Acid, Oil Palm, Liquid Waste, Ion Exchange Chromatography ABSTRAKPenelitian mengenai Pemisahan Asam Amino dari Limbah Cair Pabrik Kelapa Sawit dengan Kromatografi Penukar Ion telah dilaksanakan dari bulan Oktober sampai November 2015. Hasil hidrolisis HCl 6 N menunjukkan bahwa pembacaan absorbansi tertinggi diperoleh pada konsentrasi eluen NaCl 0,2 dan 0,6 M, sedangkan hasil hidrolisis enzim protease pembacaan absorbansi tertinggi pada eluen NaCl 0,2 dan 1 M. Tidak ada perbedaan yang signifikan pada hasil pemisahan dengan kromatografi penukar ion ini, menunjukkan bahwa konsentrasi eluen NaCl tidak terlalu berpengaruh, sehingga untuk analisis selanjutnya digunakan hanya satu konsentrasi eluen. Hasil regresi linear yang diperoleh yaitu sebesar 0,9946, hasil tersebut menunjukkan bahwa deret standar asam amino lisin mempunyai nilai yang linear karena mendekati 1. Kadar asam amino yang diperoleh pada sampel hasil hidrolisis LCPKS dengan HCl 6N yaitu sekitar 0 – 8,82 ppm dan sampel hasil hidrolisis enzim protease sekitar 0 – 4,31 ppm. Kadar asam amino yang diperoleh masih jauh dari yang diharapkan.Kata Kunci: Asam Amino, Minyak Kelapa Sawit, Limbah Cair, Kromatografi Penukar Ion
