Kajian Risiko Bencana Alam pada Tower SUTT 150 kV Bandung Timur – Ujung Berung

Infrastructure—such as transportation, telecommunic ations, sanitation, and energy— forms the backbone of a country’s economic development. Within infrastructure project s, risk management plays a critical role in mitigat ing potential losses. One such system is the High Voltage Air Duct (SUTT) , which distributes electricity from power plants— typically located far from urban centers—to end users. The 150kV East Bandung– Ujung Berung SUTT project involves 26 transmission towers supplying e lectricity from East Bandung to Ujung Berung. This study aims to identify natural disaster risks that may impact the 150kV SUTT towers in this project. T he research was conducted on-site along the East Ba ndung– Ujung Berung transmission corridor. Using a qu alitative approach and the AS/NZS 4360 risk managem ent framework, natural disaster risks were mapped and analyzed. Findings i ndicate that earthquakes pose the most significant natural disaster risk to the 26 SUTT towers. The highest-ranked risk factor iden tified is the potential for tower foundations to co llapse or shift due to seismic activity, which could lead to severe structural damage. This risk scored 18.32, p lacing it in the “very high” category. Another major risk is delayed emerg ency maintenance fo llowing a natural disaster, which can result in further deterioration and significantly reduce the towers’ service life. This risk scored 15.05, class ified as “high”.
