Identifikasi Sifat Magnetik, Salinitas, dan pH Tanah pada Lahan Pertanian di Sekitar Industri Tekstil dengan Metode Kemagnetan Batuan dan EC- pH Meter

Abstrak

Industrial activities, particularly textile industry, have the potential to pollute agricultural lands in their vicinity through waste discharge. This research aims to identify the magnetic properties, salinity, and pH of soils in agricultural areas affected by textile industry activities located in Bandung, utilizing secondary data. Soil magnetic properties are analyzed using the rock magnetism method to measure magnetic susceptibility values, which can be influenced by magnetic minerals from anthropogenic and pedogenic sources. Soil salinity is measured using an Electrical Conductivity (EC) meter to determine electrical conductivity which is correlated with dissolved salt content, while soil pH is measured using a pH meter to determine the level of acidity or alkalinity of the soil. The experiment at the different places, there is the area which located closer by pollution source (a) and area which far from pollution source (b). After we’ve done the measurement, we got some data, there are pH (a) =7,8, pH(b) = 7,1, TDS dan EC (a) = 0,161 - 0,313 dan 0,34 - 0,627, TDS dan EC (b) = 0,06 - 0,206 dan 0,127 - 0,419, cfd % (a) = 0,66 – 2,4 % , cfd % (b) = 3,26 – 3,76 %. That data is shown the pollution of the soil at the place, it is area (a), which specification are pH (>>), TDS and EC (>>) and cfd % (<<), it means the soil is alkali with big grain and has high salt concentration.
