Abstract
Penelitian ini dilatarbelakangi oleh pentingnya stabilitas tegangan pada gedung bertingkat yang memiliki beban peralatan laboratorium sensitif seperti Gedung SFD UNJ. Tujuan penelitian ini adalah untuk mengevaluasi besaran jatuh tegangan (voltage drop) pada sistem distribusi busbar trunking (busduct) di Tower A dan Tower B serta memvalidasi keandalan sistem terhadap standar PUIL 2020. Metode penelitian yang digunakan adalah deskriptif kuantitatif dengan membandingkan hasil perhitungan manual terhadap hasil simulasi menggunakan perangkat lunak ETAP 12.6.0. Data teknis berupa panjang penghantar, impedansi, dan load schedule dianalisis pada variasi beban 25%, 50%, 75%, dan 100%. Hasil penelitian menunjukkan bahwa nilai jatuh tegangan yang terjadi pada kondisi beban maksimal di kedua tower berkisar antara 0,01 V hingga 2,2 V atau dengan persentase maksimal sebesar 0,5%. Nilai tersebut masih berada jauh di bawah batas maksimal yang diizinkan oleh PUIL 2020 yaitu sebesar 4%. Perbandingan antara perhitungan manual dan simulasi ETAP menunjukkan selisih rata-rata (error) yang sangat kecil, yakni berkisar antara 0,2% hingga 0,5%. Hal ini menunjukkan bahwa pemodelan sistem distribusi pada ETAP telah valid dan sistem busbar trunking eksisting memiliki performa yang sangat optimal dalam menjaga stabilitas tegangan untuk mendukung operasional beban sensitif di Gedung SFD UNJ. ***** This research was motivated by the importance of voltage stability in high-rise buildings equipped with sensitive laboratory equipment, such as the SFD Building at UNJ. The purpose of this study was to evaluate the magnitude of voltage drop in the aluminum busduct distribution system in Tower A and Tower B, and to validate the system's reliability against the PUIL 2020 standards. The research method used was descriptive quantitative by comparing manual calculation results based on conductor technical parameters with simulation results using ETAP 12.6.0 software. Technical data, including conductor length, impedance, and load schedules, were analyzed at load variations of 25%, 50%, 75%, and 100%. The results showed that the voltage drop values occurring under maximum load conditions in both towers ranged from 0.01 V to 2.2 V, with a maximum percentage of 0.5%. These values are well below the maximum limit allowed by PUIL 2020, which is 4%. The comparison between manual calculations and ETAP simulations showed a very small average difference (error), ranging from 0.2% to 0.5%. This indicates that the distribution system modeling in ETAP is valid and the existing aluminum busduct system performs optimally in maintaining voltage stability to support the operation of sensitive loads at the SFD Building UNJ.
