Abstract

Construction activities generally use concrete as the main material, one of which is in reinforced concrete columns that function to withstand vertical loads and distribute them to the lower parts of the structure. In the Multimedia Nusantara School project, which was carried out independently, formwork work often faced the challenge of completing the project quickly and at a low cost. Therefore, this study was conducted to examine effective and efficient work methods that reduce costs while maintaining quality, namely through the application of a zoning system. In this study, the work area was divided into two scenarios, namely 1 work zone and 2 work zones, to see the differences in their effectiveness. In addition, the types of column formwork used consisted of two types of materials, namely fiberglass formwork and conventional formwork. The main objective of this study was to determine the optimal work zone division model and to analyze the relationship and role of the zoning system in the time and cost efficiency of column formwork work. This research method was carried out using a qualitative descriptive approach using project planning data. The analysis was carried out using Microsoft Excel software to analyze the implementation time and cost estimates. The results of the study indicate that the application of two zones is the most optimal model for column formwork work. The application of the zoning system directly affects the relationship between time efficiency and cost. The shorter the cycle time applied, the higher the implementation cost tends to be due to more intensive use of resources. Based on the analysis results, the model with 2 zones and a 7 day cycle is the most efficient option, as it can speed up completion time to 44 days with a total cost of Rp294,899,522.

Abstract

Pembangunan Jalan Tol Serang–Panimbang ditujukan untuk meningkatkan aksesibilitas kawasan selatan Provinsi Banten yang memiliki potensi pariwisata dan ekonomi tinggi, namun masih terkendala oleh waktu tempuh yang panjang serta keterbatasan kapasitas jaringan jalan eksisting. Penelitian ini bertujuan melakukan pra-studi kelayakan pembangunan jalan bebas hambatan Serang–Panimbang melalui kajian terintegrasi aspek teknis, transportasi, geoteknik, perkerasan, serta ekonomi dan finansial sebagai dasar penentuan kelayakan proyek. Metodologi yang digunakan meliputi pengumpulan data primer berupa survei lalu lintas (traffic counting), survei kecepatan perjalanan, survei topografi, serta pengujian geoteknik menggunakan Dynamic Cone Penetrometer (DCP) dan CBR, serta data sekunder dari instansi terkait. Analisis dilakukan berdasarkan ketentuan PKJI 2023, pedoman Bina Marga, dan standar perencanaan teknis jalan. Hasil kajian menunjukkan bahwa proyeksi volume lalu lintas, termasuk diverted traffic dan induced traffic, mendukung kebutuhan pembangunan jalan bebas hambatan. Perencanaan geometrik dan evaluasi geoteknik menunjukkan trase memenuhi persyaratan keselamatan dan kelayakan konstruksi, sedangkan struktur perkerasan kaku tipe Jointed Plain Concrete Pavement (JPCP) dinilai sesuai dengan beban lalu lintas rencana dan kondisi tanah dasar. Analisis ekonomi-finansial menunjukkan manfaat signifikan berupa efisiensi waktu perjalanan, penurunan biaya operasional kendaraan, peningkatan akses kawasan wisata Tanjung Lesung, serta dampak positif terhadap pertumbuhan wilayah. Secara keseluruhan, pembangunan Jalan Tol Serang–Panimbang dinilai layak untuk dilanjutkan ke tahap perencanaan teknis detail.
