DETEKSI PERAKARAN KELAPA SAWIT PADA LUBANG BIOPORI MODIFIKASI DENGAN METODE GEOLISTRIK RESISTIVITAS
Abstrak: Palm has a fibrous
root system, consisting of a primary root, secondary, tertiary and quaternary.
In general, palm root system is closer to ground level, however, in certain
cases it may penetrate deeper. One of the root functions is to absorb water and
nutrients from the soil. Palm roots dispersion can be determined by using the
geoeletric resistivity method. Geoelectric resistivity data using Wenner
configuration method is measured in three trajectory forming an equilateral
triangle on palm plant row with a variation of 9 m (AB / 2) in accordance with
palm plant spacing, with potential electrode spacing of 30 cm (MN / 2).
Collection of geoelectric resistivity data is done by injecting electric
current into the earth through two electrodes, the potential difference is then
measured through two potential electrodes. Measurements were performed by
varying the distance of the electrodes and potentials, gradually from the
smallest distance to the largest. Measurement of palm root dispersion detection
consists of 3 tracks (L1, L2, and L3). Measurements on June 24, 2014 carried
out on track 1 (L1) between rows of palm plants, track 2 (L2) between the palm
plant within the same row, and track 3 (L3) diagonally between the rows of
plants (Figure 1). Measurement on July 8, 2014 were on track 1 (L1) is between
rows of palm plants, track 2 (L2) and track 3 (L3) diagonally between the rows
of plants.Geoelectric on diagonal trajectory where modified biopore
infiltration pit is in place resulted in low resistivity values. This is
related to soil water availability, where it affects the development of the
root towards the biopore pits.
