Pengaruh Konsentrasi Oksigen Terlarut Terhadap Pengukuran Suseptibilitas Magnetik Pada Frekuensi Rendah

---

Poor water conditions are not only an indicator of environmental damage, but also a threat to the ecosystem. One of indicator water quality is determined by dissolved oxygen. In this research, an instrument was built to measure dissolved oxygen levels based on the susceptibility value of a solution at low frequencies of 1 Hz, 10 Hz and 100 Hz. A Magnetic instrument with an RC circuit are designed to produces a magnetic field, which can inspect sample solutions easily and simply. The instrument used consists of 217 turns of the primary coil and 30,000 turns of the secondary coil. The RC circuit used resistor and capacitor values of 1 MΩ and 10 μF, respectively, which produces a pole frequency of 0.016 Hz. The gradient value of the measurement solution gets smaller when the frequency is increased, the gradient value at the frequency of 1 Hz is greater than at the frequencies of 10 Hz and 100 Hz. The addition of oxygen to main solution aims to produce solutions with a concentration of 0%, 25%, 50%, 75% and 100%. The measurement results show an effect of solution concentration change on the susceptibility value, the greater the concentration of the solution, the susceptibility value increases. The instrument that is built can also detect changes in the value of the gradient on variations in concentration, frequency and diameter.
