Analisa Unsur Hara Cu dan Zn pada Daun Kelapa Sawit dengan Menggunakan Aas di Pusat Penelitian Kelapa Sawit (PPKS) Medan

Abstract

Nutrient analysis has been carried out Cu (Copper) and Zn (zinc) on palm leaves on Palm Research Center in Medan. Determination of Cu (copper) and Zn (zinc) in the leaves of palm oil with alkaline destruction method with Atomic Absorption Spectrophotometer method. The result showed that the concentration of Cu (Copper) obtained from palm leaves in the sample No. 12 329, 12 330, 12 331, 12 332 and 12 333 is 5 ppm, 7 ppm, 6 ppm, 7 ppm and 8 ppm. While the levels of Zn (Zinc) obtained from palm leaves in the sample No. 12 329, 12 330, 12 331, 12 332 and 12 333 is 30 ppm, 44 ppm, 25 ppm, 24 ppm and 26 ppm. From these results suggest that Cu and Zn levels above the optimal range.
