Abstract

Penelitian ini dilakukan pada gas turbine generator yang beroperasi di industri oil & gas sebagai peralatan utama penyedia energi listrik untuk mendukung keberlangsungan operasional. Penurunan kinerja peralatan dapat menurunkan efektivitas operasi, sehingga diperlukan evaluasi menggunakan metode overall equipment effectiveness (OEE) dan six big losses. Metode OEE digunakan untuk mengukur efektivitas peralatan berdasarkan komponen availability, performance, dan quality, sedangkan six big losses digunakan mengidentifikasi sumber kerugian yang memengaruhi kinerja peralatan. Hasil penelitian menunjukan bahwa nilai OEE pada compressor sebesar 67,02% dengan availability 83,27%, performance 93,20%, dan quality 86,35%. Combustion chamber diperoleh nilai OEE sebesar 21,28% dengan nilai availability 83,27%, performance 67,79%, dan quality 37,70%. Nilai OEE turbin sebesar 55,99% dengan nilai availability 83,27%, performance 87,71%, dan quality 76,66%, sedangkan generator memiliki nilai OEE sebesar 25,69% dengan nilai availability 83,27%, performance 41,75%, dan quality 73,91%. Hasil perhitungan efisiensi menunjukkan bahwa efisiensi compressor sebesar 90,96%, combustion chamber sebesar 86,35%, turbin sebesar 93,62%, generator sebesar 90,63%, dan gas turbine generator secara keseluruhan sebesar 21,74%. Hasil penelitian menunjukan bahwa nilai OEE seluruh equipment masih berada di bawah standar world-class sebesar (85%). Penurunan OEE disebabkan oleh rendahnya nilai performance dan quality yang menyebabkan tingginya reduce speed losses (RSL) dan product defect losses (PDL). Compressor didapatkan nilai RSL dan PDL sebesar 6,80% dan 13,65%, combustion chamber sebesar 32,20% dan 62,30%, turbin sebesar 12,29% dan 23,34%, dan generator sebesar 58,24% dan 26,09%.Perusahaan dapat menyusun strategi pemeliharaan yang lebih efektif serta meningkatkan kualitas operasional pada setiap equipment gas turbine generator guna meningkatkan keandalan sistem sehingga nilai OEE dapat ditingkatkan hingga mencapai standar world-class.

This research was conducted on a gas turbine generator (GTG) operating in the Oil and Gas industry as a primary equipment for electricity generation to support operational continuity. A decline in equipment performance may reduced operational effectiveness, therefore a evaluation was carried out using the overall equipment effectiveness (OEE) and six big losses. is required. Accordingly, this study employed the overall equipment effectiveness (OEE) and The OEE method was used to evaluate equipment effectiveness based on three components : availability, performance, and quality, while the six big losses method was applied to identify the major sources of losses affecting equipment performance. The results indicate that the OEE value of the compressor was 67,02%, with availability 83,27%, performance 93,20%, and quality 86,35%. The combustion chamber achieved an OEE value of 21,28% with availability 83,27%, performance 67,79%, and quality 37,70%. The turbine recorded an OEE value of 55,99%, with availability 83,27%, performance 87,71%, and quality 76,66%. Meanwhile, the generator obtained an OEE value of 25,69%, with availability 83,27%, performance 41,75%, and quality 73,91%. The efficiency analysis indicated efficiencies of 90,96% for the compressor, 86,35% for the combustion chamber, 93,62% for the turbine, 90,63% for the generator, and 21,74% for the overall gas turbine generator. The results indicate that the OEE values of all equipment remain below the world-class standard of 85%. The low OEE values were primarily caused by reduced performance and quality, which contributed significantly to reduce speed losses (RSL) and product defect losses (PDL). The compressor, the RSL and PDL values were 6,80% and 13,65%, the combustion chamber 32,20% and 62,30%, the turbine 12,29% and 23,34, and the generator 58,24% and 26,09%. Based on the findings, more effective maintenance strategies and improvements in operational quality can be implemented for each GTG equipment component to enchae system reliability an increase OEE values toward the world-class standard.
