ANALISIS DIFUSI LARUTAN PUPUK MELALUI DINDING MORTAR ARANG SEKAM PADI
Abstract: The aim of this
reasearch is to determine difussion coefficient of nutrient solution through
rice husk charcoal mortar walls. This research used completely randomized
design (CR) with factorial arrngement which consisted of factors. The first
factor, the material composition ratios of mortars (cement : sand : rice husk
charcoal), consisted of two levels: P 1 (1:3:3) and P 2 (1:3:4). The second
factor, the concentration of nutrient consisted of ree levels, namely K 1 (3
mS/cm), K 2 (6 mS/cm), and K 3 (9 mS/cm). Data set was analyzed by using ANOVA,
then followed by using LSD at 5% significant level. Anova showed that there was
interaction between mortar material composition and nutrient concentration. The
best diffusion coefficient was found in the treatment P 2 K 1 and P 2 K 2
(1:3:4 and the nutrient concentrations 3 mS/cm, 6 mS/cm). Nutrient solution in
the treatments could pass through the walls of mortar very well, so that it
could be used as a means of fertigation.
