RANCANGAN PENYALUR PETIR TIPE ELEKTROSTATIS DI GEDUNG TERMINAL KEDATANGAN BANDAR UDARA ABDULRACHMAN SALEH MALANG

Gedung terminal kedatangan Bandara Abdulrachman Saleh Malang memiliki tingkat risiko tinggi terhadap sambaran petir, sebagaimana terbukti pada insiden tahun 2019 yang merusak perangkat elektronik vital. Sistem proteksi petir konvensional yang terdekat dinilai tidak mampu menjangkau seluruh area gedung secara optimal. Penelitian ini bertujuan merancang sistem penyalur petir tipe elektrostatis yang lebih efektif dan luas jangkauannya. Metode yang digunakan adalah Research and Development (R&D) tingkat 1. Penelitian dilakukan dengan beberapa tahapan mulai dari pengambilan data, analisis data, dan perancangan desain. Pengambilan data dilakukan dengan mengumpulkan data primer melalui observasi lapangan dan wawancara teknis, serta data sekunder dari BMKG dan literatur teknis. Analisis dilakukan berdasarkan standar IEC 62305-3 dan perhitungan tahanan pentanahan mengacu pada IEEE Std 142-2007. Desain sistem dibuat menggunakan AutoCAD dan divalidasi melalui simulasi 3D menggunakan Google SketchUp. Hasil akhir berupa Detail Engineering Design (DED), Bill of Quantity (BOQ), dan Rancangan Kerja dan Syarat (RKS) menunjukkan bahwa sistem penyalur petir elektrostatis yang dirancang dapat mencakup seluruh area gedung secara efektif. Sistem ini berpotensi mengurangi risiko sambaran petir secara signifikan, meningkatkan keselamatan operasional, serta menjadi referensi teknis untuk penerapan sistem proteksi petir yang lebih andal di lingkungan bandara.

The arrival terminal building at Abdulrachman Saleh Airport in Malang is classified as a high-risk area for lightning strikes, as evidenced by a 2019 incident that damaged critical electronic equipment. The nearest conventional lightning protection system was deemed inadequate to provide full coverage of the building area. This study aims to design a more effective electrostatic lightning protection system with broader coverage. The research employed a Level 1 Research and Development (R&D) method, consisting of several stages: data collection, data analysis, and system design. Primary data were collected through field observations and technical interviews, while secondary data were obtained from BMKG and technical literature. The analysis refers to the IEC 62305-3 standard and grounding resistance calculations based on IEEE Std 142-2007. The system was designed using AutoCAD and validated through 3D simulations with Google SketchUp. The final outputs include a Detail Engineering Design (DED), Bill of Quantity (BOQ), and Specifications and Work Plan (RKS). The results show that the proposed electrostatic system can effectively cover the entire terminal area, significantly reduce lightning risk, enhance operational safety, and serve as a technical reference for implementing a modern lightning protection system in airport environments.
