Abstract

Jacket Structure merupakan salah satu bangunan lepas pantai yang paling banyak digunakan di perairan Indonesia. Anjungan ini efektif untuk digunakan pada perairan dangkal. Namun dalam pembuatannya sering sekali mengalami keterlambatan pada proses fabrikasi. Sehingga di butuhkan evaluasi pada saat proses fabrikasi dengan menggunakan metode earned value analysis (EVA). Metode ini digunakan untuk mengetahui peringatan dini ketika proyek fabrikasi jacket structure berlangsung. Selain itu, dengan menggunakan metode EVA kita dapat meminimalisir keterlambatan proyek fabrikasi. Pada tugas akhir ini, dilakukan evaluasi terhadap kinerja, biaya dan waktu terhadap proyek pembangunan jacket structure dengan hanya meninjau pekerjaan fabrikasi. Metode EVA diterapkan pada penelitian ini dengan memperhitungkan PV (Plan value), EV (Earned Value) dan AC (Actual Cost). Nilai tersebut didapatkan karena adanya nilai BAC (Budgeted at Completed) sebesar $3,266,786.93 dan waktu pengerjaan 26 minggu untuk proyek fabrikasi Jacket Structure. Dari nilai tersebut bisa mencari dan menghitung nilai kumulatif PV, EV dan AC di setiap peninjauan, dari perhitungan kumulatif bisa mencari nilai Variance di setiap peninjauan. Hasil dari penilitian ini menunjukkan bahwa kinerja dari PT.X pada minggu ke-26 dari aspek biaya dan waktu menunjukan bahwa pelaksanaan proyek ini memperoleh kerugian bernilai negative (-$275,578.32) berdasarkan Cost Variance dan mengalami keterlambatan bernilai negative (- $551,156.63) berdasarkan Schedule Variance. Perkiraan biaya yang dibutuhkan sebesar $3,567,754.11 dan perkiraan waktu untuk menyelesaikan proyek adalah 36.65 minggu. =================================================================================================== Jacket Structure is one of many type of offshore structure which is mainly used in Indonesian waters. This structure is effective in shallow water. However in terms of fabrication, they are prone to delay. In that case, evaluation using earned value analysis is needed in fabrication process. This method is benefiting in early recognition at start of the fabrication process. Nevertheless, by using EVA method, Fabrication project delay can be reduced. In this report, evaluations of cost and time towards jacket structure construction were done by considering fabrication process. EVA method implemented in this report was calculating Plan Value (PV), Earned Value (EV) and Actual Cost (AC). Those values are calculated towards Budgeted at Completed (BAC) value, which is $3,266,786.93 and working period at 26 weeks for jacket structure fabrication project. From those numbers, cumulative values of PV, EV, and AC in every observation can be calculated. Finally, from cumulative values, Variance numbers can be calculated in every observation. This report shows that in PT.X at weeks 26th, this project develop negativity, (-$275,578.32) based upon cost variance, and delayed at (-$551,156.63) based upon schedule variance in terms of cost and time. Estimated cost needed to complete this project is $3,567,754.11 and estimated time needed for this project is 36.65 weeks.
