Abstract

Most farmers in Indonesia really need potassium fertilizer to meet the needs of K nutrients in the soil, because most of the potassium nutrients in the soil are still relatively small. Janjang ash is an organic solid waste from the burning of oil palm mills which is used as fertilizer because it contains high K2O elements. Under these circumstances an attempt was made to find alternatives in the formation of potassium sulfate (K2SO4). One of the formation of potassium sulfate (K2SO4) is by reacting potassium oxide (K2O) found in the extract of janjang ash palm oil with sulfuric acid (H2SO4). The purpose of this research is to study the effect of temperature and time on the rate of potassium sulfate formation. To determine the reaction order and the reaction rate constant of the formation of potassium sulfate from the extract of janjang ash palm oil with sulfuric acid. Research on the kinetics of the reaction of potassium sulfate formation was carried out by first extracting the janjang ash palm oil with a ash ratio of 100 gr / liter aquadest. Ash extract was reacted with sulfuric acid (H2SO4). The result is then titrated with 0.5 N NaOH. The variables used are time (40, 50, 60, 70, 80 minutes) and temperature (50, 60, 70, 80, 90 ºC). From the results of this study, the reaction of potassium sulfate formation from oil palm and ash sulfuric longitudinal extracts followed the second-order reaction with the greatest potassium sulfate conversion was 93.01% at 90 ºC and 80 minutes. The value of the reaction rate constant (k) obtained is k = 1,5 x 10-9 e-5480/T
