Analisis Sistem Kelistrikan di Intensive Care Unit (ICU) Rumah Sakit Mitra Keluarga Pondok Tjandra Sidoarjo

Sistem kelistrikan Intensive Care Unit (ICU) berperan kritis dalam keselamatan pasien, namun sering menghadapi permasalahan kualitas daya, keandalan sistem cadangan, dan kesesuaian standar. Untuk itu, dilakukan perhitungan dan evaluasi sistem kelistrikan ICU Rumah Sakit Mitra Keluarga Pondok Tjandra Sidoarjo. Metode penelitian menggunakan pendekatan deskriptif-analitis dengan pengukuran parameter kelistrikan menggunakan power analyzer, observasi lapangan, dan wawancara. Perhitungan meliputi analisis kualitas daya, keandalan sistem cadangan, dan kesesuaian terhadap IEC
60364-7-710 dan Permenkes RI No. 40/2022. Hasil menunjukkan sistem disuplai PLN melalui LVMDP dengan cadangan genset 350 kW dan UPS 10 kVA. Kualitas daya menunjukkan tegangan 392-401,6 V (deviasi 2,25%), frekuensi 50 Hz, faktor daya 0,914, namun ketidakseimbangan beban mencapai 96,7% dengan fasa R menanggung 65,3% beban total. Keandalan sistem menunjukkan waktu transfer genset 13 detik, runtime UPS 12 menit (beban 80%), dan availability 99,96%. Sistem memenuhi 60% parameter IEC 60364-7-710 dan 80% Permenkes No. 40/2022 dengan utilisasi 34,2%. Rekomendasi meliputi redistribusi beban antar fasa, penggantian baterai UPS, pemisahan jalur beban kritis-non kritis, dan implementasi monitoring real-time.

The Intensive Care Unit (ICU) electrical system plays a critical role in patient safety, yet it frequently faces issues with power quality, backup system reliability, and compliance with standards. Therefore, a calculation and evaluation of the ICU electrical system at Mitra Keluarga Hospital, Pondok Tjandra, Sidoarjo, were conducted. The research method used a descriptive-analytical approach, measuring electrical parameters using a power analyzer, field observations, and interviews. The calculations included analysis of power quality, backup system reliability, and compliance with IEC 60364-7-
710 and Indonesian Minister of Health Regulation No. 40/2022.
The results showed that the system was supplied by PLN through the LVMDP (Light-Powered Vault) with a 350-kW generator backup and a 10 kVA UPS. Power quality showed a voltage of 392-401.6 V (2.25% deviation), a frequency of 50 Hz, and a power factor of 0.914, but the load imbalance reached
96.7%, with the R phase carrying 65.3% of the total load. System reliability demonstrated a generator transfer time of 13 seconds, a UPS runtime of 12 minutes (80% load), and 99.96% availability. The system met 60% of IEC 60364-7-710 parameters and 80% of Indonesian Minister of Health Regulation No. 40/2022, with a utilization rate of 34.2%. Recommendations included interphase load redistribution, UPS battery replacement, separation of critical and non-critical load paths, and implementation of real-time monitoring.
