PELINDIAN UNSUR KALIUM (K) DAN NATRIUM (Na) MATERIAL VULKANIK HASIL ERUPSI GUNUNG MERAPI 2010 (Simulasi Laboratorium)
Abstrak: This research was
conducted at the Greenhouse Laboratory of the Faculty of Agriculture, Sebelas
Maret University Surakarta, in March 2011. The aim of the study was to determine
the relationship between the rainfall (synthetic) the number of elements
Potassium (K) and Sodium (Na) were leached in volcanic material from the
eruption of Mount Merapi. This study used artificial rainfall simulation
approach to treatment is based on the
phenomenon of the eruption of Mount Merapi, Yogyakarta, Central Java by
examining the leaching elements Sodium (Na) and Potassium (K) are swapped in
the above-ground volcanic material Andisol. The experiments in this study using
a completely randomized design (CRD) consisting of 3 to 5 treatments the sample
depth artificial rain (water sprinkling) in 3 replications, namely 1 (22 mm x 1
day (22 mm)), 2 (22 mm x 10 days (220 mm)), 3 (22 mm x 20 days (440 mm)), 4 (22
mm x 30 days (660 mm)), 5 (22 mm x 45 days (990 mm)), and control ( 45 days
field) with 3 replicates each. The variables measured were pH H2O, available K
and Na, K and Na total, CEC, texture. Analysis of the data using the F test at
the level of 95% or Kruskal-Wallis, to compare the mean between treatments
using DMR test at the level of 95% or Mood Median, whereas to determine the
relationship between variables used correlation test.
The results showed that administration of rainfall of 22 mm / day is able
to affect the leaching of potassium and sodium in the volcanic material from
day 10. Leaching was significantly visible on day 30 with a decrease in
available K and Na volcanic material at a depth of 0-15 cm in diameter (K
23.08%) (23.08% Na) and at a depth of 15-30 cm (K 21, 42%) (23.08% Na), and the
addition of K and Na are available at a depth of >30 cm in the form of land
Andisol (K 16.67%) (23.53% Na) from the previous treatment.
