ABSTRAK Petir adalah gangguan alam yang sering terjadi di Indonesia. Maka dari itu bangunan-bangunan di Indonesia memiliki resiko lebih besar mengalami kerusakan akibat terkena sambaran petir. Intensitas petir yang tinggi di Gresik, yakni 102 hari guruh per tahun merupakan ancaman serius bagi struktur area fabrikasi baja workshop1 PT. X. Menyadari kondisi tersebut, perlu dilakukan evaluasi sistem proteksi petir sehingga dapat bekerja dengan efektif dan efisien dan tidak mengganggu proses produksi di PT. X terutama pada Line F ruang K3. Peningkatan performa sistem terhadap gangguan akibat petir dapat dilakukan dengan mengevaluasi dan merancang sistem proteksi petir eksternal (terminal udara, penghantar turun, serta sistem pentanahan) dan sistem proteksi petir internal. Dengan analisis menggunakan metode sudut proteksi ditemukan bahwa pemasanganterminal udara pada struktur bangunan masih belum dapat memberikan perlindungan yang baik pada bangunan. Evaluasi dan Perancangan Sistem proteksi Petir internal dan eksternal berdasarkan Per. No.02/MEN/1989, SNI, PUIL, dan IEEE. Sistem proteksi petir internal pada struktur bangunan sebaiknya setiap panel yang berisi peralatan elektronis dan instrumen dipasang arester yang digunakan untuk mengantisipasi efek sambaran petir tidak langsung. Sementara itu sistem proteksi petir eksternal berdasarkan metode sudut proteksi (PER No.02/MEN/1989) air terminal yang seharusnya terpasang sebanyak 16 buah, down conductorsebanyak 10 buah pada sisi kanan dan kiri bangunan, dan elektroda grounding˃ 4 buah atau dapat mengikuti down conductor agar nilai resistan pembumiannya ˂ 5Ω. Untuk tindakan preventive maintenance dapat berupa pemberian kode pada setiap groundingagar mempermudah pengecekan, serta terdapat jadwal pengecekan sistem proteksi petir.

Thus, buildings in Indonesia have a greater risk of damage due to exposure to lightning strikes. A high intensity lightning in Gresik, which is 102 days a year of thunder represents a serious threat to the structural steel fabrication workshop area 1 PT.X. Aware of these conditions, it is necessary to evaluate the lightning protection system so that it can work effectively and efficiently and does not interrupt the production process in PT. X especially on Line F of K3 room. Improved system performance against lightning disturbances can be done by evaluating and designing external lightning protection systems (air terminals, down conductors, and ground systems) and internal lightning protection systems. By analysis using angle of protection method found the installation air terminal on the structure of the building still can not provide good protection on the building. Evaluation and Design of Internal and External Lightning Protection System based on Per. No.02 / MEN / 1989, SNI, PUIL, and IEEE. Internal lightning protection system on the building structure should each panel containing electronic equipment and instruments installed arrester is used to anticipate the effects of an indirect lightning strike. Meanwhile, external lightning protection system based on protective angle method (PER No.02 / MEN / 1989) of air terminal should be installed as much as 16 units, down conductor as much as 10 units on the right and left side of the building, and grounding electrode ˃ 4 units or can follow Down conductor for the ground resistance value ˂ 5Ω. For preventive maintenance actions can be a code on every grounding to facilitate checking, and there is a lightning protection system checking schedule.
