Percepatan pada pekerjaan pondasi tiang pancang proyek Makassar New Port - Paket D, dilakukan karena proyek tersebut mengalami keterlambatan. Salah satu faktor yang menyebabkan proyek tersebut terlambat dikarenakan tidak adanya lahan yang tersedia dan beberapa faktor lain.. Percepatan dilakukan menggunakan metode Time Cost Trade Off yaitu dengan melakukan penambahan jam kerja (lembur) 2 jam ; 3 jam ; 4 jam ; dan penambahan tenaga kerja sebanyak 25% pada pekerja dan tukang. Serta melakukan perhitungan efisiensi biaya maupun efisiensi waktu percepatan, dan menghitung rasio perbandingan efisiensi biaya dan waktu. Hasil perhitungan dengan melakukan penambahan jam kerja (lembur) 2 jam ; 3 jam ; 4 jam ; dan penambahan tenaga kerja yaitu didapatkan durasi 105 hari (2 jam lembur), 98 hari (3 jam lembur), 95 hari (4 jam lembur), dan 110 hari (penambahan tenaga kerja) dibandingkan durasi normal proyek 135 hari. Perhitungan efisiensi biaya dan waktu, didapatkan efisiensi sebesar 1.526 % dan 22.222 % (2 jam lembur), 1.717 % dan 27.407 % (3 jam lembur), 1.888 % dan 29.630 % (4 jam lembur), 7.886 % dan 18,519 % (penambahan tenaga kerja). Perhitungan rasio efisiensi perbandingan durasi percepatan dengan peningkatan biaya yang dikeluarkan. Percepatan dengan melakukan penambahan jam lembur kerja selama 3 jam memiliki rasio perbandingan yang paling kecil yaitu sebesar 0,063. Tahap percepatan tersebut merupakan percepatan yang paling efektif untuk dilakukan

The acceleration of the work of the Foundation pillar of Makassar project stake New Port - Package D, done because those projects experienced delays. One of the factors that caused the project to be late due to the lack of land available and several other factors. Acceleration is performed using the methods of Time Cost Trade Off with increased working hours (overtime) 2 hours; 3 hours; 4 hours; and the addition of labor as much as 25% for workers and builders. As well as doing the calculation cost efficiency as well as the efficiency of time acceleration, and calculate the ratio a comparison of cost and time efficiency. The results of calculations with increased working hours (overtime) 2 hours; 3 hours; 4 hours; and the addition of a workforce that is obtained by the duration of 105 days (2 hours of overtime), 98 days (3 hours of overtime), 95 days (4 hours of overtime), and 110 days (additional labor) than the normal project duration 135 days. Calculation of cost and time efficiency, obtained efficiency of 1.526 % and 22.22% (2 hours of overtime), 1.717 % and 27.407% (3 hours of overtime), 1.888 % and 29.630 % (4 hours overtime), 7.886% and 18.519% (additional labor). And calculation of the efficiency ratio is a comparison of the duration of the acceleration with increased costs incurred. Acceleration with increased overtime hours of work during the 3 hours have a ratio of most small i.e. comparison of 0.063. The acceleration is the acceleration phase is the most effective thing to do
