Research  on the correlation  test  for chemical  oxygen demand and  the colors in liquid waste of oil palm plant has been conducted through three steps, they are the first lest on some liquid waste oil palm plant, test on some variations of diluting sampel and lest on the aplication of the results of the research. The test on COD and colors in liquid waste of oil palm plant show the existence of corretetion which is marked by the linear equation which is oblained and the close correlation (R).  The linear equation and correlation (R) are:  Y = 0.19 X  + 0,20 ; R = 0,99 for inlet sample and Y =  0,19 X + 0,14; R = 0,99 for outtet sample The  aplicaton  if  the  results  of  fhe research  also shows  the  difference between result of the test on COD and COD of the color test are very small. at the average of 4, 1%.
