Abstract

This research is aimed at studying the effect of heating, boiling, and acidification techniques of Sinabung Volcanic Ash (AVS) material on the total and exchangeable concentrartion of K, Ca, and Mg, to obtain a technique that can increase the exchangeable content of K, Ca, and Mg, and to produce products of agrotechnolgy containing exchangeable K, Ca, and Mg in high concentration. This experiment uses a non factorial completely randomized design. The treatments tested were 3 types of techniques consisting of: oven-heating technique of 100oC (PO), 100oC (PA) water-boiling technique, and 0.01N HCl acidification technique (US). Each treatment technique was carried out for 6 hours. The variables observed included the total content of K, Ca, and Mg (extractant ingredients H2SO4 (p) and HCl (p), and the exchangeable content of K, Ca, and Mg (NHOAc, pH 7.0), the ratio of K, Ca, and Mg to be exchangeable for the total amount, and the relative ratio between elements K, Ca, and Mg. Measurement of K, Ca and Mg elements uses the Atomic Absorption Spectrophotometer (AAS) tool. The results showed that the effect of heating technique treatment with oven 100oC (PO), boiling water 100oC (PA), and acidification techniques with 0.01 N HCl were significantly different in increasing total and exchangeable contents of K, Ca, and Mg, releasing rate of exchangeable contents of K,Ca, and Mg. Acidification technique is the best technique in increasing all the variables observed and manufacturing products of agrotechnology, followed by heating and boiling techniques. Three products were found and marked by codings of AVS-A0,01-6, AVS-O100-6, dan AVS-W100-6
