ABSTRAK
Breakwater merupakan proyek linear construction projects dengan tipe pekerjaanberulang (repetitive work activities), namun di Indonesia penjadwalan untukpekerjaan repetitive project masih menggunakan penjadwalan konvensional,khususnya pada proyek breakwater pelabuhan Kalibaru Jakarta. Metode linearscheduling dengan singularity function diaplikasikan pada pembangunanbreakwater Pelabuhan Kalibaru mengingat metode tersebut mempunyai banyakkelebihan. Dalam penelitian ini dilakukan analisa terhadap jadwal pelaksanaanrencana yang memiliki durasi pekerjaan yaitu 485 hari serta terhadap nilai bufferantar kegiatan. Hasil analisa dengan singularity function menyimpulkan denganmengoptimalkan nilai buffer antar kegiatan dapat mengurangi durasi pekerjaan.Hasil optimal yang didapat adalah durasi pekerjaan 274 hari.

ABSTRACT
Breakwater is a linear construction project with repetitive work activities, but inIndonesia scheduling for repetitive projects are still using conventionalscheduling, especially in the construction of breakwater project in KalibaruJakarta. Linear scheduling method with singularity function is applied in theconstruction of breakwater at the Port of Kalibaru considering the method hasmany advantages. In this research, an analysis of the plan implementationschedule which has duration of 485 days, and an analysis to the value of the bufferbetween activities. The results of the singularity function analysis conclude byoptimizing the value of buffers between activities can reduce the duration of thework. Optimal results are obtained work duration is 274 days.
