Abstract

The research to watch the spread of detergent waste liquid in a glass compartement has been done. The glass compartement was in dimension of 200 cm in length, 90 cm in width and 80 cm in height. This research used one dimensional and two dimensional resistivity geoelectrical method with Schlumberger configuration measurement technique. The appliance used for both method was Auto Range Resistivitymeter. In two dimensional resistivity geoelectrical method, the amount of datum point (data point) needed in this research was 102 point. The span of measurement area was 120 cm with 5 cm of electrode spacing. the result from Res2dinv Software data processing was 12.4 cm of maximum depth, which resulted by inversion process, meanwhile the spread of detergent waste liquid in horizontal axis was (2.5-5) cm in both left and right direction from the waste source, with resistivity span in (666-5367) ohm cm. Meanwhile in one dimensional resistivity geoelectrical method, the amount of data needed in this research for each sounding point was 19 data point. With (4 and (t) data and also geometry factor (K), the pseudo-resistivity price for each data point can be calculated. The data processing was done by curve matching method, continued with Resist software. The result from Resist Software dataprocessing for the first layer depth was (7.7-12) cm, with resistivity span in (116.3-497.2) ohm cm. The second's depth was m, with resistivity span in (20374.1-27743.0) ohm cm.
