Abstract
Application of resistivity method on cinchona plantation at PTPN Bukit Tunggul VIII Lembang aims on understanding the pattern of soil layer and indication of exposed area of the inorganic fertilizer residue which has caused changes in physical characteristics, moreover the resistivity values of the soil. Research comes under the implementation of Wenner-Schlumberger with small spacing for better enhancement of near surface imaging. The usage of flat base electrode is also brought up to reduce the noise of small spacing, or in other words preventing bad datum points. By using geoelectric resistivity method, it has been proven that the fertilizer into the ground can be detected as an anomaly that has a lower resistivity value compared to the medium.
