Abstract :
Dalam bidang konstruksi, metode pelaksaan haruslah singkat dan optimal namun tidak mengubah kualitas dari konstruksi tersebut. Untuk mendapatkan kualitas dan waktu yang optimal diperlukan perencanaan yang matang. Salah satu pekerjaan pada tahap perencanaan adalah merencanakan site layout. Dengan merencanakan site layout yang optimal akan meningkatkan produktivitas pekerja sehingga dapat menghindarkan terjadinya keterlambatan pekerjaan dari jadwal yang telah ditentukan. Penelitian ini dilakukan di Proyek Apartemen Grand Shamaya yang berlokasi di Kota Surabaya. Proyek Apartemen Grand Shamaya memiliki lahan proyek yang tergolong sempit karena pembangunan berada di tengah kota dan memiliki fasilitas sementara yang cukup banyak untuk memenuhi kebutuhan proyek. Untuk mendapatkan produktivitas yang optimal dan menghindarkan terjadinya keterlambatan proyek maka, perlu adanya optimasi site layout. Optimasi penataan site layout dilakukan dengan cara iteratif hingga dicapai nilai yang optimum. Letak fasilitas sementara akan diletakan dengan mempertimbangkan hubungan kedekatan antar fasilitas menggunakan Activity Relationship Chart (ARC) kemudian dihitung nilai Travelling Distance (TD), Degree of Hazard (DH), dan Travel Cost of Material Resources (TCMR). Proses tersebut harus memperhatikan batasan ? batasan yang berlaku seperti antar fasilitas tidak diperkenankan tumpang tindih dan penempatan fasilitas berada pada lahan proyek. Hasil penelitian ini didapatkan 4 alternatif skenario tata letak fasilitas sementara, dari keempat alternatif skenario tersebut dapat disimpulkan bahwa site layout pada Proyek Apartemen Grand Shamaya belum optimal. Berdasarkan Diagram hubungan TD, DH, dan TCMR didapatkan nilai paling optimum menggunakan metode pareto-optimal solution terjadi pada skenario 2 dengan Travelling Distance (TD) = 26671.02 atau memiliki penurunan sebesar 1.38% dari skenario 0 (eksisting), Degree of Hazard (DH) = 502.92 atau memiliki penurunan sebesar 3.25% dari skenario 0 (eksisting), dan Travel Cost of Material Resources (TCMR) = 78421.689 atau memiliki penurunan sebesar 14.01% dari skenario 0 (eksisting). ============================================================ ========================================================================= In the field of construction, the implementation method must be short and optimal but should not compromise the quality of the construction. Achieving optimal quality and efficiency requires careful planning. One of the tasks during the planning stage is to design the site layout. Planning an optimal site layout will enhance worker productivity and help prevent work delays according to the predetermined schedule. This research was conducted at the Grand Shamaya Apartment Project, located in the city of Surabaya. The project site for the Grand Shamaya Apartment is relatively narrow due to its development in the middle of the city, but it has sufficient temporary facilities to meet the project's requirements. To achieve optimal productivity and avoid project delays, it is necessary to optimize the site layout. An iterative approach was employed in the optimization research on-site layout arrangement for the Grand Shamaya Apartment Project until an optimal value was reached. The location of temporary facilities was determined by considering the proximity between facilities, using an Activity Relationship Chart (ARC). The values for Traveling Distance (TD), Degree of Hazard (DH), and Travel Cost of Material Resources (TCMR) were then calculated. This process considered relevant constraints, such as ensuring facilities do not overlap and determining suitable placements within the project land. Four temporary facility layout scenarios were evaluated based on this study's findings. It can be concluded that the site layout of the Grand Shamaya Apartment Project is suboptimal. The relationship diagram for TD, DH, and TCMR indicated that the most optimal values, determined using the Pareto-optimal solution method, were achieved in scenario 2. In this scenario, Traveling Distance (TD) = 26671.02 or decreased by 1.38% compared to scenario 0 (existing), Degree of Hazard (DH) = 502.92 or decreased by 3.25% compared to scenario 0 (existing), and Travel Cost of Material Resources (TCMR) = 78421.689 or decreased by 14.01% compared to scenario 0 (existing).
