Abstract
Gempa menghasilkan pembebanan pada suatu Jacket Platform melalui interaksi
gerakan tanah dan karakteristik respon struktur. Tugas akhir ini menganalisa keruntuhan
Jacket Platform dengan variasi Peak Ground Acceleration (PGA) berbasis resiko.
Metode pushover non-linear untuk mendapatkan Reserve Strength Ratio (RSR) dengan
incremental lateral load berupa beban gempa hingga struktur collapse. Penerapan analisa
pushover non-linear dalam hal material dan geometri. Analisa non-linear menghasilkan
RSR yang lebih akurat dibading analisa linear. Diperoleh RSR terkecil pada PGA 0,25g
yaitu 2,082 dengan probability of failure (pof) sebesar 0,0461. Resiko Jacket Platform
akibat beban gempa termasuk dalam Risk level 2 dalam API RP 2 SIM (System Integrity
Management).

Seismic load on a Jacket Platform through the interaction of ground movement and the
character response of the structure. This final academic project is to analyze the risk of
Jacket Platform collapse with Peak Ground Acceleration (PGA) variations. Non-linear
pushover method used to obtain the Reserve Strength Ratio (RSR) with incremental
seismic lateral load until the structure collapse. Application of non-linear pushover
analysis in terms of material and geometry non-linearity. Using non-linear approach, the
RSR produces more optimist and accurate than linear approach. The smallest RSR of
2,082 is found on 0.25g PGA with probability of failure (pof) 0.0461. Platform Jacket
risk category due to seismic loads are included in the Risk level 2 in API RP 2 SIM
(System Integrity Management).
