Below is a gyrator circuit with an equivalent inductance of 10.6H. The gyrator has to be at ground so the capacitor and inductor are reversed in sequence from your schematic but that makes no difference to the circuit operation.
The circuit input is connected to the junction of the 220kΩ resistor and 1µF cap in your circuit. LR8, the 0.1µF cap, and the A50 pot are also part of your circuit. The gyrator circuit is the circuitry to the right of A50.
With the 220KΩ resistor in series and the 6.8kΩ resistor to ground in your circuit, the 30V signal should be attenuated sufficiently to about 1V so the op amp should work ok at a 5V supply.
The op amp should be a rail-to-rail type such as a
TLV2374. I added the resistors and capacitor to provide the pseudo-ground at 2.5V for the op amp input.
Edit: Changed op amp number
