dc.description.abstractThe non-optimal land use due to the lack of micronutrients content in the soil results in less agricultural productions. It is necessary to know whether the plant nutritions in the soil are sufficient or not in order to optimize the crop productions. Iron (Fe) as one of the soil micronutrients is potentially easy to be detected using magnetic principle. This research was conducted by analyzing the magnetization curve of iron whose concentrations in the soil were varied around its need in the soil. The magnetization curve is obtained using an RC integrator circuit and a double solenoid. The results show the amount of iron affects the gradient of the magnetization curve, which represents its susceptibility. The greater the mass of iron being measured, the greater the resulting gradient. The gradient obtained is 0.00038 T·m/A·g. The corner frequency of the suitable RC integrator is 0.0032 Hz. For this corner frequency value, the output signal is quite linear and the voltage change not too small. Measurement of the gradient of iron with frequency variations of 1 Hz and 10 Hz gives different error results. The resulting error at frequency of 1 Hz is 8.29 × 10-7 T·m/A·g, while at a frequency of 10 Hz is 8.94 × 10-6 T·m/A·g. The greater the frequency used in the measurement, the smaller the voltage generated so that the magnetic field value B obtained is also getting smaller, which is decreasing the signal to noise ratio.en_US
