Abstract
In the welding process, discontinuities or defects usually occur, therefore a non-destructive test is needed to ensure that the weld results are good to support strong materials and avoid material failure. One of the development tools for non-destructive testing is Magnetic Induction Tomography (MIT). MIT is one of the tomography techniques that utilizes magnetic induction to detect damage or defects in materials. This research aims to optimize the sensor in detecting void defects both containing empty space (air) and inclusion defects in the form of solid material and can distinguish the type of material. The material objects used are steel, copper, and aluminum. This research was conducted with transmitter and receiver coil solenoid sensors with diameters of 0.5 cm and 1.5 cm respectively with data retrieval frequencies between 100 kHz - 1MHz. The results show that the MIT sensor is able to detect air-filled void defects and solid material-filled inclusion defects and can detect differences in material type. At a frequency of 150 kHz, the difference in impedance value of steel, copper and aluminum objects is 0.0333 ohm, 0.0334 ohm and 0.0335 ohm, respectively. The impedance measurement results of voids containing empty space (air) and inclusion defects obtained values of 0.0334 ohms and 0.0331 ohms. From these results, the MIT sensor is able to detect void defects in the form of air and inclusion defects in the form of solid materials and can distinguish steel, copper and aluminum material objects.

| Additional Information: | Pada proses pengelasan biasanya terjadi diskontinuitas atau cacat, oleh karena itu diperlukan suatu pengujian non -destruktif untuk memastikan bahwa hasil las yang baik untuk menunjang material yang kuat dan menghindari kegagalan material. Salah satu pengembangan alat untuk pengujian non-destruktif adalah Magnetic Induction Tomography (MIT). MIT merupakan salah satu dari teknik tomografi yang memanfaatkan induksi magnetik untuk mendeteksi kerusakan atau cacat pada material. Penelitian ini bertujuan untuk mengoptimalkan sensor dalam mendeteksi cacat void baik yang berisi ruang kosong (udara) maupun cacat inklusi berupa material padat serta dapat membedakan jenis material. Objek material yang digunakan adalah baja, tembaga, dan aluminium. Penelitian ini dilakukan dengan sensor solenoida koil transmitter dan receiver berdiameter masing-masing sebesar 0,5 cm dan 1,5 cm dengan frekuensi pengambilan data antara 100 kHz - 1 MHz. Hasil penelitian ini menunjukkan bahwa sensor MIT mampu mendeteksi cacat void berisi udara dan cacat inklusi berisi material padat serta dapat mendeteksi perbedaan jenis material. Pada frekuensi 150 kHz, perbedaan nilai impedansi pada objek material baja, tembaga, dan aluminium masing-masing sebesar 0,0333 ohm, 0,0334 ohm dan 0,0335 ohm. Hasil pengukuran impedansi void berisi ruang kosong (udara) dan cacat inklusi diperoleh nilai 0,0334 ohm dan 0,0331 ohm. Dari hasil-hasil tersebut, sensor MIT mampu mendeteksi cacat void berupa berisi udara dan cacat inklusi berupa material padat serta dapat membedakan objek material baja, tembaga, dan aluminium. | |||||||||
