Abstract
The Section 6B Toll Road project in the Capital City of Nusantara (IKN), East Kalimantan, experienced several constraints in the implementation of slab on pile works using the full slab precast method. This method caused various issues, including high operational costs due to the requirement of large-capacity cranes, difficulties in mobilizing panels weighing 25–30 tons per unit, increased risk of material damage during transportation and installation, and suboptimal road surface quality caused by joints between panels. These conditions potentially reduced project efficiency in terms of both cost and construction time. Therefore, this study aims to evaluate the improvement of project value through the application of the Value Engineering (VE) concept by replacing the full slab precast method with the half slab precast + topping slab method on the bridge structure at STA 1+375 to STA 1+540.540. This research employs a quantitative descriptive-analytical method by applying the six stages of the Value Engineering Job Plan, namely the information phase, function analysis, creativity phase, evaluation, development, and presentation and implementation. Secondary data were used, including technical drawings, cost estimates, unit price analysis, and construction schedules. These data were analyzed to compare cost performance and construction duration between the full slab precast method and the half slab + topping slab method. The results indicate that the implementation of the half slab + topping slab method reduced the construction duration from 75 days to 69 days. In terms of cost, the full slab precast method showed a potential loss of IDR 255,800,000, whereas the half slab precast + topping slab method generated a profit of IDR 1,405,000,000. Expert validation results also confirmed that the alternative method is more efficient and feasible for implementation in the field. Thus, the application of Value Engineering is proven to increase project value through cost efficiency and schedule acceleration without reducing the structural function. Keywords: Value Engineering, Slab on Pile, Half Slab Precast + Topping Slab, Cost Efficiency, Time Efficiency Proyek Jalan Bebas Hambatan Seksi 6B di Ibu Kota Nusantara (IKN), Kalimantan Timur, menghadapi kendala pada pelaksanaan pekerjaan slab on pile yang menggunakan metode full slab precast. Metode tersebut menimbulkan berbagai permasalahan, antara lain tingginya biaya operasional akibat penggunaan crane berkapasitas besar, kesulitan mobilisasi panel dengan berat 25–30 ton per unit, potensi kerusakan material selama pengangkutan dan pemasangan, serta kualitas permukaan jalan yang kurang optimal akibat sambungan antar panel. Penelitian ini bertujuan untuk mengevaluasi peningkatan nilai proyek melalui penerapan konsep Value Engineering (VE) dengan mengganti metode full slab precast menjadi metode half slab precast + topping slab pada struktur jembatan STA 1+375 hingga STA 1+540. Penelitian dilakukan menggunakan metode kuantitatif deskriptif analitis dengan menerapkan enam tahapan Job Plan Value Engineering, yaitu tahap pengumpulan informasi, analisis fungsi, kreativitas, evaluasi, pengembangan, serta presentasi dan implementasi. Data sekunder berupa gambar teknis, rencana anggaran biaya, analisis harga satuan, dan jadwal pelaksanaan dianalisis untuk membandingkan kinerja biaya dan waktu antara kedua metode. Hasil analisis menunjukkan bahwa penerapan metode half slab precast + topping slab mampu mengurangi durasi pelaksanaan pekerjaan dari 75 hari menjadi 69 hari. Dari aspek biaya, metode full slab precast menunjukkan potensi kerugian sebesar Rp255.800.000, sedangkan metode half slab precast + topping slab menghasilkan keuntungan sebesar Rp1.405.000.000. Validasi pakar juga menyatakan bahwa metode alternatif tersebut lebih efisien dan layak diterapkan di lapangan. Kata Kunci : Value Engineering, Slab On Pile, Half Slab Precast + Topping Slab, Efisiensi Biaya, Efisiensi Waktu.
