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

Tanon District is about 14 Km from the district capital Sragen. The beauty of the Tanon sub-district can be seen from the environment that is still maintained and beautiful, plus the friendliness and wisdom of the local residents. This road is a connecting road between Purwodadi-Gemolong-Tanon-Sidoharjo-Sragen. This road section is an effective route used by heavy vehicles and commercial vehicles from the Sragen area to the Gemolong area because it can shorten the travel time. Therefore on this road section it is necessary to carry out road repairs so that traffic can run well and smoothly. The analysis is carried out in several steps. The first step is to collect CBR (California Bearing Ratio) and LHR (Average Daily Traffic) data. The second step is to calculate the rigid pavement design. After that, the calculation of the thickness of the concrete slab is analyzed using the SNI Pd T-14-2003 method. The results of the calculation analysis for Rigid Pavement Planning for Karangasem Road Section, Tanon District KM 5 + 100 – 8 + 100 Using the PD T – 14 – 2003 method, the calculation results for the subgrade CBR value = 4.5%. The results of the pavement thickness calculation obtained 10 cm thick foundation and 16 cm thick concrete slab. And the calculation of the reinforcement we get longitudinal reinforcement ø9 – 250 mm, transverse reinforcement ø8 – 350 mm, dowel bar spokes ø28 – 450mm, spacing 300mm, length mm, tie bars ø13 – 650 mm, spacing 700 mm

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
