Abstract
Pengembangan infrastruktur di Institut Teknologi Sepuluh Nopember (ITS) perlu memperhatikan keberadaan fasilitas vital, terutama kabel listrik bawah tanah yang berfungsi sebagai penyalur energi listrik bagi utilitas dan gedung di lingkungan ITS. Berdasarkan informasi Biro Sarana dan Prasarana ITS, saat ini ITS belum memiliki peta lokasi distribusi kabel listrik bawah tanah, sehingga keberadaan kabel tersebut hanya dapat dikenali melalui patok penanda di atas permukaan tanah. Penelitian ini bertujuan untuk melakukan pemetaan lokasi kabel listrik dengan tegangan 20 kVA yang ada di bawah permukaan tanah wilayah ITS di FT-SPK. Metode Geofisika yang digunakan untuk pemetaan yaitu Metode Ground Penetrating Radar (GPR) dengan frekuensi 670 MHz yang melalui tahap pengolahan seperti Static Correction, Gain, Bandpass filter, Background Removal, Time Depth Conversion. Selain itu juga digunakan Pipe locator RD8200 untuk menyisir arah kabel listrik yang divalidasi dengan penggalian. Selain itu, dari hasil data tersebut didukung dengan menggunakan metode GPS Geodetik untuk mendapatkan koordinat yang tepat. Hasil yang didapat dari penelitian ini berupa peta kemenerusan kabel listrik bawah tanah 20 kVA dari arah Tenggara hingga Barat pada kedalaman 0,50 m hingga 1.30 m dan estimasi diameter kabel sebesar 0,08 m dengan nilai RMSE alat Pipe locator terhadap hasil penggalian sebesar 1,9%. Hasil penelitian ini menunjukkan bahwa penggunaan alat GPR dan Pipe Locator mampu untuk mendeteksi adanya kemenerusan kabel listrik dibawah permukaan dan bermanfaat untuk pemetaan utilitas di lingkungan ITS.

Infrastructure development at Institut Teknologi Sepuluh Nopember (ITS) must consider the presence of vital facilities, particularly underground power cables that supply electricity to utilities and buildings across the ITS campus. According to the ITS Bureau of Facilities and Infrastructure, there is currently no existing map of underground power cable distribution, with their presence only marked by surface-level stakes. This study aims to map the location of 20 kVA underground power cables within the Faculty of Civil, Planning, and Geo Engineering (FT-SPK) area of ITS. The geophysical method employed is Ground Penetrating Radar (GPR) with a frequency of 670 MHz, processed through steps including Static Correction, Gain, Bandpass Filtering, Background Removal, and Time-Depth Conversion. Additionally, the RD8200 pipe locator was used to trace the direction of power cables, validated by soil excavation. GPS geodetic measurements were also used to obtain accurate coordinates. The results of this research include a map showing the continuity of 20 kVA underground power cables extending from the southeast to the west at depths ranging from 0.50 m to 1.30 m, with an estimated cable diameter of 0.08 m. The RMSE value of the pipe locator compared to excavation results is 1.9%. This study demonstrates that the use of GPR and a pipe locator is effective for detecting underground power cable continuity and is beneficial for utility mapping within the ITS campus.
