Abstract

Several studies have report that a percolation test suits are required for planning permissions for all proposed new homes which do not have access to public mains. A percolation test is a test to determine the water absorption rate of soil in preparation for the building of a septic drain field (leach field) or infiltration basin. percolation testing is simply observing how quickly a known volume of water dissipates into the subsoil of a drilled hole of known surface area. Percolation tests are conducted through experimental activities in the field as the area planned in the catchment area. Experiments were performed to determine the soil’s ability to pass water expressed in minutes per inch. In general the percolation test is done manually with numericalscale observation. The problem so far is the difficulty of determining the limit of water level in the test hole because it is based on visual and wet-looking tools as a hint of water level position. Researchers see opportunities to create new tools. This exciting research is followed up by creating another tool model named “Digital Percolation Meter” which results can be read directly on the monitor screen. Research through field experiment aims to produce a digital measuring instrument that works electrically and used as a means of measuring soil absorption that has not been in the market. Implementation of the device test carried out directly through percolation tests such as procedures that have been used, namely preparing 6 holes as deep as 60 cm and saturated through filling holes with water for 24 hours. This way to get the condition of the land as if it was like the condition at the height of the rainy season. The measurement result of Percolation Meter Digital is compared with the result of measurement of manual percolation test method that has been used, to get the number of soil impregnation. Both measurements were analyzed through the AUC curve. Testing data delivery time (ON) at different levels of recharge levels conducted at a height of 1 inch, 3 inch and 5 inch, the researchers put the initial sensor at the top. Then the timing results compared to using stopwatch as gold standart. Results from time data submissions show in 5 Inch and 3 inch has 100% sensitivity, and in 1 Inch level has 98%. Lower limit water level sensor using infrared and photodiode. Testing data delivery time is completed at different levels of recharge levels conducted at the level of 5 inch, 3 inch and 1 inch, Researchers put the sensor level water sensor at the bottom. The result show in 5 inch have 98% sensitivity,3 inch has 96% and 1 inch has 92% Sensitivity.
