ABSTRACT
The nonoptimal land use due to the nutrient content in the soil results in not maximal
agricultural production. For that, it is necessary to know whether the plant nutrition in
the soil is sufficient or not. Measurement of micronutrients in the soil is a very
important process to determine soil fertility and the adequacy of plant needs for
essential nutrients in its growth. One of the micronutrients needed by the soil is iron,
which is needed in small amount. The iron content in the soil can be determined by
magnetic measurement methods because iron is a ferromagnetic material. This
research was conducted by analyzing the magnetization curve of the ferrous material
whose concentrations in the soil were varied. The results show the mass size affects
the gradient of magnetization curve of iron sand, the greater the mass of iron sand
being measured, the greater the resulting gradient. The gradient obtained is 0.00038
a.u/g. The corner frequency of a suitable RC integrator is 0.0032 Hz. For this corner
frequency value, the output signal is quite linear and the voltage change is not too
small. Measurement of the magnetic susceptibility of iron sand 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 a.u, while at a frequency of 10 Hz is 8.94 × 10-6 a.u.
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.
Keywords: Susceptibility, Magnetic field, Ferromagnetic, Magnetization curve, Iron
sand.
