Abstract
Sistem PLTGU ini dituntut untuk berjalan dengan optimal demi memenuhi demand akan listrik di Indonesia, maka dari itu perlu untuk dilakukan pengukuran efektivitas unit pembangkit listrik, salah satunya adalah unit Gas Turbine 1.1 atau GT 1.1. Pengukuran efektivitas ini dilakukan dengan metode Overall Equipment Effectiveness di mana didapatkan nilai OEE unit GT Blok 1.1 belum mencapai nilai standar dengan persentase 82.62% dan dilanjutkan dengan metode Six Big Losses yang menyimpulkan bahwa kontributor utama tidak tercapainya nilai standar OEE adalah reduced speed losses sebesar 87.43% dan idling and minor stop losses sebesar 11.50%. Selain itu juga menggunakan metode Failure Mode & Effect Analysis ditemukan 22% mode kegagalan pada GT 1.1 memiliki tingkat criticality medium dan 78% memiliki tingkat criticality yang high dengan mode kegagalan tertinggi ditemukan pada HRSG yaitu kebocoran pipa superheater dengan skor RPN 144. Kedua tingkat mode kegagalan masih tergolong tolerable risk dan identifikasi mode kegagalan dilanjutkan dengan menggunakan metode Reliability Centered Maintenance untuk menentukan tindakan yang tepat dalam menangani mode kegagalan yang mungkin terjadi

This PLTGU system is required to run optimally in order to meet demand for electricity in Indonesia, therefore it is necessary to measure the effectiveness of power generating units, one of which is the Gas Turbine 1.1 or GT 1.1 unit. This effectiveness measurement was carried out using the Overall Equipment Effectiveness method where it was found that the OEE value of the GT Block 1.1 unit had not reached the standard value with a percentage of 82.62% and continued with the Six Big Losses method which concluded that the main contributor to not achieving the standard OEE value was reduced speed losses of 87.43% and idling and minor stop losses of 11.50%. Apart from that, using the Failure Mode & Effect Analysis method, it was found that 22% of the failure modes in GT 1.1 had a medium criticality level and 78% had a high criticality level with the highest failure mode found in the HRSG, namely a superheater pipe leak with an RPN score of 144. Both levels of failure mode is still classified as a tolerable risk and identification of failure modes is continued using the Reliability Centered Maintenance method to determine appropriate actions to handle failure modes that may occur
