    Abstract

    Dalam dunia konstruksi, terdapat dua metode utama dalam pekerjaan beton, yaitu metode konvensional (cast in situ) dan metode pracetak (precast). Penelitian ini membandingkan pelat lantai eksisting metode konvensional pada proyek Museum Al-Kitab GBI Summarecon Bandung dengan sistem precast Hollow Core Slab (HCS) sebagai alternatif modifikasi. Metode konvensional dikerjakan langsung di lokasi, memerlukan banyak bekisting, tenaga kerja, dan pengawasan ketat, sehingga waktu pelaksanaannya lebih lama. Metode precast HCS tidak memerlukan bekisting, memiliki kontrol kualitas yang lebih baik karena diproduksi di pabrik, serta membutuhkan lebih sedikit tenaga kerja, meskipun memerlukan alat berat untuk proses pemasangan elemen struktur. Perbedaan karakteristik kedua metode ini memberikan dampak terhadap biaya pelaksanaan, durasi pekerjaan, serta berat struktur yang dihasilkan. Penelitian ini menggunakan pendekatan deskriptif kuantitatif yang disesuaikan dengan variabel-variabel penelitian, berfokus pada permasalahan aktual serta fenomena konstruksi yang terjadi saat ini. Analisis dilakukan dengan membandingkan kedua metode konstruksi tersebut berdasarkan tiga aspek utama, yaitu biaya, waktu pelaksanaan, dan berat struktur pelat lantai. Berdasarkan hasil analisa terhadap dua metode pelat lantai, yaitu cast in situ dan precast hollow core slab (HCS), diperoleh bahwa sistem pelat precast HCS memiliki keunggulan dalam hal waktu pelaksanaan yaitu lebih cepat 46 hari atau 29,3% dibandingkan metode cast in situ. Namun, dari sisi biaya, metode precast HCS justru lebih mahal sebesar Rp264.422.444,67 atau 4,11% dibandingkan metode konvensional. Di sisi lain, dari aspek berat struktur, pelat dengan sistem precast HCS terbukti lebih ringan sebesar 1.303.111,08 kg atau 30,78% dibandingkan pelat cast in situ, sehingga memberikan keuntungan dalam pengurangan beban total struktur bangunan. In the construction industry, there are two main concrete methods: the conventional (cast in situ) method and the precast method. This research compares the existing floor slab using the conventional method in the Museum Al Kitab GBI Summarecon Bandung project with the Hollow Core Slab (HCS) precast system as a modification alternative. The conventional method is executed directly on-site, requiring extensive formwork, labor, and strict supervision, resulting in longer construction time. In contrast, the HCS precast method does not require formwork, offers better quality control as it is manufactured in factories, and requires less labor, although heavy equipment is needed for the installation process. These differing characteristics impact project costs, construction duration, and structural weight. This study uses a quantitative descriptive approach adapted to the research variables, focusing on current construction issues and phenomena. The analysis compares the two construction methods based on three main aspects: cost, execution time, and slab structural weight. Based on the results, the HCS precast system shows advantages in terms of time, being 46 days or 29.3% faster than the cast in situ method. However, in terms of cost, the HCS precast method is 4.11% more expensive, with an additional Rp 264,422,444.67. On the other hand, in terms of structural weight, the HCS slab is 30.78% lighter, reducing the total load on the building structure.
