Abstract

Pada pembangunan proyek perumahan, perencanaan dibutuhkan untuk memperhitungkan berbagai variabel pekerjaan yang menyangkut sumber daya yang terbatas seperti waktu dan biaya. Tujuan dari penelitian ini  adalah mendeskripsikan aktivitas jaringan kerja yang optimal dengan metode Critical Path Method (CPM), perencananaan kelayakan yang optimal dengan metode Program Evaluation and Review Technique (PERT), dan mendeskripsikan waktu dan biaya proyek yang efisien dengan metode Time Cost Trade Off (TCTO) pada proses pembangunan perumahan. Jalur kritis dari penerapan metode critical path method (CPM) dimulai dari pekerjaan persiapan (A) sampai pekerjaan pagar (AB), tetapi ada satu yang tidak termasuk pada jalur kritis yaitu pekerjaan plafond (H). Pekerjaan tersebut memiliki nilai slack 25, artinya kegiatan tersebut memiliki kelonggaran waktu pengerjaan selama 25 hari. Dari penerapan metode program evaluation and review technique (PERT), proyek perumahan dapat diselesaikan lebih cepat dari kurun waktu normal selama 555 hari dengan waktu yang diharapkan 547 hari dengan peluang 64,8%. Sedangkan dari penerapan metode time cost trade off (TCTO), efisiensi waktu pengerjaan proyek dengan penambahan pekerja adalah 5,76% dengan selisih percepatan 32 hari kerja dan efisiensi biayanya adalah 0,156% dengan biaya optimal sebesar Rp. 6.753.245.793Kata kunci: Critical Path Method (CPM), Program Evaluation and Review Technique (PERT), Time Cost Trade Off (TCTO).  Time Exchange Analysis and Cost Using Time Cost Trade Off (TCTO) Method in Housing Development Projects in PT. XABSTRACTIn the construction of housing projects, planning is needed to account for the various work variables involving limited resources such as time and cost order to achieve the stated objectives and achieve the desired results. The purpose of this research is to describe optimal network activity from the application of Critical Path Method (CPM) method, to describe optimal feasibility planning from applying of Program Evaluation and Review Technique (PERT) method, and to describe time and cost of efficient project from application of Time method Cost Trade Off (TCTO) on the housing development process. The critical path from the application of the method of critical path method (CPM) starts from the preparatory work (A) to the fence work (AB), but there is one that is not included in the critical path ie the ceiling work (H). The work has a slack value of 25, meaning that the activity has a working time clearance for 25 days. From the implementation of the evaluation and review technique (PERT) program method, the housing project can be completed faster than the normal time period of 555 days with the expected time 547 days with a chance of 64.8%. While from the time cost trade off (TCTO) method, the time efficiency of project work with the addition of worker is 5.76% with the acceleration difference of 32 working days and the cost efficiency is 0.156% with the optimum cost of Rp.6.753.245.793.
