Abstract

The palm waste is a the rest of the oil palm plantations that are not included in the main product or a by-product of palm oil processing. One type of solid waste palm oil industry is the oil palm shell. Oil palm shell has many elements of K,P, Na, Ca, Mg, Zn. Where one element of K is usually used to make liquid fertilizer of potassium sulfate. The process of making a liquid fertilizer of potassium sulfate made by burning palm shells to ashes. Then the ash was dissolved in 500 ml of aquadest water and retrieved by filtering the extract. Mix 20 ml solution (K2O) and 20 ml of H2SO4 concentration of 0,08;0,09; 0,1; 0,2; 0,3 M into a glass beaker. Turn styrer for 30, 40, 50, 60, 70 minutes by keeping the solution temperature at 70 ° C conditions. Do stirring with a speed of 200 rpm. Then do the analysis on the product obtained is K, and SO4. From this study obtained the best results in the addition of K2O with the addition of 0.08M H2SO4 at 60 minutes with stirring K in K2O fertilizer composition of 6.022,01 mg /L and SO4 at 5.384,02 mg / L.
