Abstract
Perusahaan Pembangunan Konstruksi bertujuan membangun proyek apartemen di Surabaya. Dalam perencanaannya, proyek ini membangun 3 tower yang berada pada satu podium. Awal pembangunan proyek ini direncanakan pada Agustus 2017, namun hingga bulan November 2017 masih belum dibangun. Pada bulan November, seharusnya progres dari proyek pembangunan apartemen sebesar 40% untuk aktivitas Bored Piled, tetapi kondisi aktual dari proyek masih mencapai 0%. Keterlambatan ini dikarenakan adanya proses pentahapan ulang oleh tim planning. Yaitu dengan merencanakan kembali tahap pambangunan apartemen akan dibangun secara parallel dengan 3 tower langsung atau sequence dengan 1 tower terlebih dahulu. Dalam pembangunan proyek ini akan mendapatkan penalti jika pengerjaan proyek melebihi waktu yang telah disepakati. Penjadwalan proyek dengan strategi sequence memiliki durasi 1135 hari dan selesai pada 11 Mei 2021 yang artinya melebihi deadline. Sehingga butuh dibentuk strategi yang tepat untuk mengejar waktu penyelesaian proyek apartemen. Penelitian ini bertujuan untuk mempercepat proses pembangunan proyek dengan cara menjadwalkan kembali schedule yang sudah direncanakan agar dapat mengejar waktu untuk penyerahan unit apartemen kepada costumer. Dalam strategi sequence diselesaikan dengan percepatan proyek yaitu menambahkan jam kerja lembur selama 2 jam per hari pada aktivitas yang berada di lintasan kritis. Dalam strategi parallel, penjadwalan proyek memiliki durasi 930 hari dan selesai pada 19 0ktober 2020 namum memiliki keterbatasan resource karena dalam strategi ini membangun 3 tower secara parallel. Terdapat 9 aktivitas yang menimbulkan konflik penggunaan sumber daya, yaitu aktivitas E2, MEP2, MEP3, MEP4, MEP5, E5, A19, A23, dan MEP8. Untuk aktivitas MEP2, MEP3, MEP4 dan MEP5 diselesaikan dengan menambahkan jumlah pekerja mechanical electrical (ME) sebanyak 46 orang. Untuk aktivitas E2, E5, A19, A23, dan MEP8 diselesaikan dengan menggeser waktu mulai aktivitas. Berdasarkan penyelesaian tersebut, pada strategi sequence mengalami peningkatan estimasi biaya sebesar Rp 12.994.731.250. Total biaya pembangunan proyek apartemen dengan strategi sequence menjadi Rp 370.711.140.572. Setelah mengalami percepatan, strategi sequence memiliki durasi 807 hari dan selesai pada tanggal 17 Juni 2020. Dalam strategi parallel menimbulkan penambahan biaya sebesar Rp 640.800.000. Total biaya untuk proyek pembangunan apartemen dengan strategi parallel sebesar Rp Rp 360.941.209.322. Setelah mengalami pergeseran, penjadwalan proyek pada strategi parallel selesai pada 24 Desember 2020 dengan durasi 996 hari. Artinya penjadwalan proyek dengan strategi parallel tidak melewati deadline. Kriteria pemilihan strategi berdasarkan penambahan biaya yang paling minimal serta tidak melewati batas toleransi tambahan 6 bulan setelah Oktober 2020. Berdasarkan hasil penjadwalan proyek dengan strategi parallel dan sequence, penambahan biaya yang paling minimal terdapat pada strategi parallel. Strategi parallel juga tidak melewati deadline yang telah ditentukan yang jatuh pada bulan April 2021 (6 bulan setelah Oktober 2020). Artinya dalam penelitian ini, strategi parallel merupakan strategi yang dipilih.
English Abstract
Construction firm aimed to develop apartment project in Surabaya. In its planning, this project would build 3 towers which lies in one podium. Initial start of this project was planned on August 2017, however, until November 2017 it was still not yet initiated. In November, the progress of this apartment development project should be about 40% for Bored Piled activity, however, the actual condition of this project was still 0%. This delay was due to re-phasing process conducted by the planning team. They were re-planning the apartment development phases which would be conducted in parallel with 3 towers simultaneously or in sequence with 1 tower at a time. In this development project, it would gain penalty if project implementation was overdue. Project scheduling using sequence strategy has the duration of 1135 days, and would be finished in May 11, 2021, which means exceeding the deadline. Therefore, appropriate strategy should be used to pursue the deadline. This study was aimed to accelerate project development process by re-scheduling in order to pursue the delivery of apartment unit toward customer. In sequence strategy, it conduct project acceleration is by increasing overtime about 2 hours per day for activities that lies in critical projection. In parallel strategy, project scheduling has the duration of 930 days and would be finished in October 19, 2020 however it has resource limitation because this strategy would build 3 towers in parallel. There were 9 activities that raise the conflict regarding resource use, those are E2, MEP2, MEP3, MEP4, MEP5, E5, A19, A23 and MEP8 activities. For MEP2, MEP3, MEP4 and MEP5 activities, it was completed by increasing the amount of mechanical electrical (ME) worker about 46 workers. For E2, E5, A19, A23 and MEP8 activities, it was completed by shifting the start time of the activities. Based on this solution, sequence strategy would create an increase in cost estimation about Rp 12.994.731.250. Total cost of apartment development project using sequence strategy would become Rp 370.711.140.572. After acceleration, sequence strategy would have the duration of 807 days and would be completed in June 17, 2020. In parallel strategy, it would create an increase in cost estimation about Rp 640.800.000. Total cost of apartment development project using parallel strategy would become Rp 360.941.209.322. After experiencing shifting, project rescheduling with parallel strategy would be completed in December 24, 2020 with duration of 966 days. It means that project scheduling with parallel strategy did not exceed the deadline. Strategy selection criteria were based on the minimum extra cost and it should not pass the tolerance limit of 6 months after October 2020. Based on the result of project scheduling using parallel and sequence strategies, minimum extra cost was obtained from parallel strategy. Parallel strategy also did not passed the given deadline of April 2021 (6 months after October 2020). It means that in this study, parallel strategy was the selected strategy to be used in the project.
