Abstract
Permasalahan sering timbul dalam proyek konstruksi, salah satu permasalahan yang paling banyak dijumpai adalah keterlambatan progres kerja. Keterlambatan progress kerja harus segera diselsaikan agar suatu proyek selesai pada kurun waktu yang telah ditentukan.. Penjadwalan ulang merupakan solusi agar proyek bisa diselesaikan dengan tepat waktu, produktivitas pekerjaan yang sudah terlaksana dihitung terlebih dahulu agar diketahui durasi diperlukan untuk menyelsaikan suatu proyek yang telah berjalan. Setelah itu dibuat Network Planning untuk mengetahui pekerjaan-pekerjaaan yang melewati lintasan kritis. Studi kasus dalam penelitian ini adalah proyek Pembangunan Trotoar dan Bangunan Pelengkap Jalan di Kota Admnistrasi Jakarta Selatan Kecamatan Tebet. Dari hasil penelitian didapat j enis pekerjaan yang melewati jalur kritis adalah Pekerjaan Pipa PVC Diameter 10”, Pemasangan Batu Kali, Pekerjaaan Pipa PVC Diamaeter 6”, Pekerjaan Kotak Mulut Air Beton Precast, Pekerjaan Kansteen Precast K-300, Pekerjaan Trotoar beton K250, Pekerjaan Trotoar Homogenus Tile, dan Pekerjaan Trotoar Stamp Concrete. Produktivitas pekerjaan sebelum penjadwalan ulang untuk pekerjaan Balok Perkuatan Trotoar 2,319 m3/hari, Pasangan Batu kali 5,251 m3/hari , Pekerjaan Beton Jepit Uk. 10x20 18,696 m/hari, Pekerjaan Beton Jepit Uk. 10x50 8,419 m/hari, Pekerjaan Gutter Beton Precast 17,196 m/hari, Pekerjaan Kansteen Precast 15,215 m/hari , Pekerjaan Kotak Mulut Air Beton 4,078 unit/hari, Pekerjaan Pipa PVC Diameter 4” 19,056 m/hari, Pekerjaan Pipa PVC Diameter 6” 16,215 m/hari, Pekerjaan Pipa PVC Diameter 10” 32,48 m/hari, Pekerjaan trotoar Beton K-250 6,664 m2/hari, Pekerjaan Trotar Batu Alam Andesit 18,604 m2/hari, Pekerjaan Totoar Stamp Concrete 35,457 m2/hari, Pekerjaan Totoar Homogenus Tile 2,577 m2/hari, Pekerjaan Totoar Paving Block 6cm 4 m2/hari. Produktivitas pekerjaan setelah penjadwalan ulang untuk pekerjaan Balok Perkuatan Trotoar 2,323 m3/hari, Pasangan Batu kali 9,449 m3/hari , Pekerjaan Beton Jepit Uk. 10x20 22,411 m/hari, Pekerjaan Beton Jepit Uk. 10x50 10,907 m/hari, Pekerjaan Gutter Beton Precast 30,936 m/hari, Pekerjaan Kansteen Precast 27,371 m/hari , Pekerjaan Kotak Mulut Air Beton 5,578 unit/hari, Pekerjaan Pipa PVC Diameter 4” 28,458 m/hari, Pekerjaan Pipa PVC Diameter 6” 23,042 m/hari, Pekerjaan Pipa PVC Diameter 10” 50,103 m/hari, Pekerjaan trotoar Beton K-250 7,947 m2/hari, Pekerjaan Trotar Batu Alam Andesit 22,881 m2/hari, Pekerjaan Totoar Stamp Concrete 44,32 m2/hari, Pekerjaan Totoar Homogenus Tile 3,1 m2/hari, Pekerjaan Totoar Paving Block 6cm 4 m2/hari. Waktu keseluruhan Proyek Pembangunan Trotoar dan Bangunan Pelengkap Jalan di Kota Asministrasi Jakarta Selatan Kecamatam Tebet sebelum dilakukan penjadwalan ulang adalah 168 Hari hari, namun setelah dilakukan percepatan sehingga durasinya menjadi 154 hari. Berarti durasi pelaksanaan dapat berkurang sebesar 14 hari. Kata Kunci :Keterlambatan, Lintasan Kritis, Penjadwalan Ulang, Produktivitas in work progress. Delays in work progress must be resolved immediately so that a project is completed within a predetermined period of time. Rescheduling is a solution so that the project can be completed on time, the productivity of work that has been carried out is calculated in advance so that it is known the duration needed to complete an ongoing project. After that, a Network Planning is made to find out the jobs that pass the critical path. The case study in this research is the Sidewalk Construction Projects and Road Complement Installation on South Jakarta, Tebet Region.. From the results of the analysis, the types of work that pass through the critical path are PVC Pipe Installation Diameter10”, Rubble Massonry, PVC Pipe Installation Diameter 6”, Precast Concrete Grill, Kansteen Precast K-300 Installation, Concrete Pavement Work, Homogeneous Tile Pavement Work, and Stamp Concrete Pavement Work. Work productivity before rescheduling for Pavement Reinforcement beams 2,319 m3/day, Rubble Massonry 5,251 m3/day, Concrete Curb Work Size 10x20 18,696 m/day, Concrete Curb Work Size 10x50 8,419 m/day, Precast Concrete Gutter Work 17,196 m/day, Kansteen Precast Work 15,215 m/day, Precast Concrete Grill 4,078 units/day, PVC Pipe Installation Diameter 4 "19,056 m/day, PVC Pipe Installation Diameter6" 16,215 m/day, PVC Pipe Installation Diamete 10 ”32,48 m/day, K-250 Concrete sidewalk work 6,664 m2/day, Andesite Natural Stone Pavement Work 18,604 m2/day, Stamp Concrete Pavement Work 35,457 m2/day, Homogeneous Tile Pavement Work 2,577 m2/day, Paving Block Pavement Work 4 m2/day. Work productivity after rescheduling for Pavement Reinforcement Beams work 2,323 m3/day, Rubble Massonry 9,449 m3/day Concrete Curb Work Size 10x20 22,411 m/day, Concrete Curb Work Size 10x50 10,907 m/day, Precast Concrete Gutter Work 30,936 m/day, Kansteen Precast Work 27,371 m / day Precast Concrete Grill Work 5,578 units/day, PVC Pipe Installation Diameter 4" 28,458 m/day, PVC Pipe Installation Diameter 6" 23,042 m/day, PVC Pipe Installation Diameter 10" 50,103 m / day, Concrete pavement work K-250 7,947 m2/day, Andesite Stone Pavement Work 22,881 m2/day, Stamp Concrete Pavement Work 44.32 m2/day, Homogenous Tile Pavement Work 3,1 m2/day, Paving Block Pavement Work 4 m2/day. The total time of Sidewalk Construction Projects and Road Complement Installation on South Jakarta, Tebet Region before the rescheduling was 168 days, but after the speed up it was cut to 154 days. This mean duration of execution can be reduced by 14 days. Key Word : Critical Path, Delays, Produktivity, Rescheduling
