Analisa Kadar Karbon di dalam Tanah Perkebunan Kelapa Sawit PT Minanga Ogan secara Titrimetri

Abstract

Have been done analysis value of elemen carbon organic in palm plantation land PT. Minanga Ogan by the way of titrimetry in Pusat Penelitian Kelapa Sawit (PPKS) Medan, with adding K2Cr2O7 1N and H2SO4(P) at the sample, and then it was liquided by aquadest, after that it was stayed the 30 minutes. Then add concentrated H3PO4(P) 85% and indicator difenilamine and tittatred by FeSO4 1N. From the result give the lowest level of organic carbon is 1,58% dan the highest is 1,93%. And means 1,75% or below 2%. Based the properties of land chemistry, the best organic carbon level is 2-3%.
