Abstract

Proyek bangunan perumahan dan bangunan pemukiman (residential construction), adalah suatu proyek pembangunan perumahan atau pemukiman berdasarkan pada tahapan pembangunan yang serempak dengan penyediaan prasarana penunjang. Proyek konstruksi memiliki kendala, antara lain adalah keterlambatan waktu pelaksanaan pekerjaan dan pembengkakan biaya. Tujuan penelitian ini adalah untuk menganalisis durasi waktu yang optimal dan efisien pada proyek pembangunan perumahan menggunakan metode CPM (Critical Path Method). Penelitian ini menggunakan metode Critical Path Method (CPM). Yang dimana data dalam penelitian ini berasal dari jadwal pekerjaan (time schedule) dan rencana anggaran biaya yang dibuat manajemen Pembangunan Perumahan Griya Sejahtera Colomadu 2. Data yang terkumpul dianalisis dengan menggunakan metode CPM lalu dicari dengan jalur / lintasan pekerjaan kritisnya menggunakan jaringan kerja (network planning), setelah diperoleh batas waktu maksimum pekerjaan selanjutnya akan dipercepat menggunakan metode Critical Path Method (CPM). Kemudian untuk analisis optimasi biaya pada penelitian ini, menggunakan metode percepatan dengan alternatif penambahan tenaga kerja. Berdasarkan hasil penelitian didapatkan bahwa proyek Pembangunan Perumahan Griya Sejahtera Colomadu 2 mengalami keterlambatan waktu pelaksanaan pekerjaan dan pembengkakan biaya, yaitu dengan total durasi 242 hari kerja, dan durasi normal pekerjaan kritisnya adalah 190 hari kerja. Hasil perhitungan percepatan dengan alternatif penambahan tenaga kerja memiliki total durasi 152 hari dan memiliki total biaya upah tenaga kerja sebesar Rp 46.993.580,88.

Abstract

In construction projects, implementation requires heavy equipment to expedite all stages in process. The use of heavy equipment serves to shorten project implementation time and optimize a job. Therefore, the use of heavy equipment in construction projects is expected to accelerate expected work. The use of heavy equipment in construction projects is expected to facilitate existing work and heavy equipment to be used must be selected in an efficient and economical manner. A heavy equipment combination used in earthworks on the Moxy Hotel development project on Jl. Slamet Riyadi, Keprabon, Banjarsari District, Surakarta City is a Kobelco CAT 320D excavator, a Canter 120 Ps dump truck and a Jove JVR 180 D bore machine. The methods used in this research are survey methods and analytical methods. The survey method is used to determine number of heavy equipment in field, heavy equipment type while analytical method is used to determine time heavy equipment is used in the Moxy Hotel Development Project in Surakarta. After an analysis of variations in the duration of heavy equipment that is appropriate and can be used optimally is an alternative because it is more effective and efficient than the calculation of composition analysis and in the field, the time required is also more optimum. With an alternative composition of heavy equipment, namely 1 unit of excavator and 4 units of dump trucks for earthworks, and for foundation drilling work, 2 units of bore machines are needed.

Abstract

The Cost Budget Plan (RAB) is an important step in a project because it is a reference for making an agreement on the payment method and calculation framework that will be announced as well as the estimated costs required. This study aims to compare and obtain more efficient estimation results according to Contractor based on the SNI method. Data collection method used in this final study is by using Secondary data, namely by collecting information on labor and material prices from the Contractor, as well as from the SNI Guidelines. Based on the results of this study, the amount of the RAB for the PMI Boyolali Building Construction Project if based on the price of the implementing contractor for the construction is Rp. 4,431,436,659. Furthermore, RAB amount for the PMI Boyolali Building Project Construction if calculated using the Boyolali Regency unit price analysis in 2023 is Rp. 4,613,231,520. And the work that has a large difference between RAB for Implementation Costs in the PMI Boyolali Building Construction Work and the RAB based on the Boyolali Regency AHSP 2023 is the highest deviation compared to other work descriptions, namely having a total difference of -Rp. 94,935,992.04, namely in the job description: concrete work (structural), concrete work (non-structural), wall work, plastering work, ceramic and floor work, and sanitation work
