THE EFFECT OF COAL WASTE BOTTOM ASH SURALAYA STEAM POWER PLANT AS A GROWING MEDIUM FOR OIL PALM SEEDLINGS

Abstract

The purpose of this study was to compare the combination of planting media, including soil and solid organic fertilizer type, and bottom ash. The experiment used the Randomized Complete Block Design method. The design was achieved through a combination of organic fertilizer types A, B, C, D, E, F, G, H, I, J, K, L, and M, along with soil media. The number of treatments consisted of thirteen, repeated three times. The ratio of planting media 67% soil and 33% Solid organic fertilizer bottom ash D  type (organic material derived from legumes and Tithonia diversifolia can provide a height of oil palm seedlings 28.57 cm at the age of twelve weeks after planting (WAP).  At the same age and the same combination ratio, ion uptake and absorption of the best of potassium (K) by oil palm seedlings. The good Shoot Root ratio was given by a combination of media, 67% soil and 33% solid organic fertilizers, and bottom ash. Similarly, in the oil palm rhizosphere, the balance of media 67% soil and 33% solid organic fertilizer bottom ash was found to contain microorganisms Lactobacillus sp, Streptomyces sp, and Bacillus sp
