Abstract

This study aims to determine the economic feasibility of local road maintenance scenario in West Bandung Regency with case study of the Cangkorah Street. After knowing the International Roughness Index (IRI) value based on the IKP value from the results of a direct survey using IKP guidelines, the economic feasibility analysis is carried out based on a road maintenance scenario, while the maintenance scenario being tested is a do-something scenario, by doing road maintenance in the form of overlay once every 5 years in 10 year time compared by a do-nothing scenario that is not doing any maintenance for the next 10 years. The research instruments used were prediction of the performance of the Cangkorah Street Pavement for the next 10 years, determine road maintenance scenarios, maintenance budget plans, calculate Vehicle Operational Costs (VOC) for each scenario, and time value. The results of this study are: (1) The budget plan for the maintenance of the Cangkorah Street in the do-something scenario with overlays 3 times in 10 years is Rp. 4,168,019,982, (2) The actual VOC for the do-nothing scenario was Rp. 57,345,718,978 and the actual VOC for the do-something scenario was Rp. 3,132,189,189 with VOC savings was Rp. 54,213,529,789, (3) The time value of the scenario for the next 10 years obtained savings of Rp. 399,241,414, (4) The feasibility of do-something scenario from an economic point of view shows that the scenario is feasible with a NPV of Rp. 36,674,480,627>0 and a BCR of 11,39 >1.

Abstract

This study aims to determine the economic feasibility of the local road maintenance scenario in West Bandung Regency with a case study of Cangkorah Street. As a strategic road to pass through the route to the city of Bandung and have a heavy traffic with a lot of heavy vehicles pass the road, roads must be maintained in order to create a safe and comfortable road for passengers. There are several ways to maintain the road, one of them is direct survey using IKP guidelines. The result from IKP value by using IKP guidelines will produce in an International Roughness Index (IRI) values the economic feasibility analysis is carried out based on a road maintenance scenario, while the maintenance scenario being tested is a do- something scenario, by doing road maintenance in the form of overlay once every 5 years in 10 year time compared by a do-nothing scenario that is not doing any maintenance for the next 10 years. The research instruments used were prediction of the performance of the Cangkorah Street Pavement for the next 10 years, determine road maintenance scenarios, maintenance budget plans, calculate Vehicle Operational Costs (VOC) for each scenario, and time value. The conclusion of the study is comparing to the scenarios, do-nothing and do-something, the feasibility of do- something scenario from an economic point of view shows that the scenario is feasible with NPV is Rp. 36,674,480,6270 and a BCR of 11.391.
PENGARUH PENAMBAHAN SERAT BAJA (STEEL FIBER) TERHADAP KUAT TEKAN DAN KUAT TARIK BELAH PADA BETON NORMAL Zulpanani, A.; Hendry, Hendry; Sirait, Togar; Juarti, Ery Radya; Kusuma, Yusmiati

Abstract

Beton normal merupakan beton yang memiliki kuat tekan di bawah 41,4 MPa, dan beton pada mutu ini saat ini menjadi salah satu material yang banyak digunakan dalam dunia konstruksi. Beton adalah suatu campuran yang terdiri dari bahan semen, agregat dan air serta addmixture. Menurut SNI 03-6468-2000 berdasarkan kuat tekannya beton terbagi dua jenis : Beton normal dengan  < 41,4 MPa dan beton mutu tinggi dengan  ≥ 41,4 MPa. Menurut ACI 544.3R-84, Serat baja didefinisikan sebagai serat baja yang mempunyai bentuk kecil-kecil yang rata atau bergelombang, yang didapat dari hasil leburan ekstrak serat-serat baja, yang dalam pemakaianya tersebar merata dalam campuran beton segar dengan aspek rasio yaitu panjang serat dibagi dengan diameter serat (l/d) antara 12,7 mm – 63,5 mm. Dalam penelitian ini variasi serat baja dibuat masing-masing 0%, 4% dan 6% terhadap campuran beton yang dibuat, dengan jumlah benda uji 4 buah untuk kuat tekan dan 4 buah untuk split test (tarik tak langsung) pada umur 14 hari dan 28 hari. Dari hasil pengujian menunjukan bahwa pemakaian serat baja dengan kadar 6% untuk beton normal dapat meningkatkan kuat tekan dan kuat tarik dari beton yang bersangkutan, dari 25,91 MPa dan 2,80 MPa menjadi 36.99 MPa dan 3.96 MPa.

Abstract

Scheduling and cost estimation are essential for successful construction projects, including the revitalization of Taman Mini Indonesia Indah and the Promenade Bridge development. To improve efficiency and effectiveness, this study applies Building Information Modeling (BIM), using Tekla Structures 2022 for 3D modeling and Quantity Take-Off. The model provides detailed volume data, which—alongside daily and weekly reports—is used for cost analysis and scheduling. BIM integration enables better visualization, planning, and resource management throughout the project lifecycle. The result of the study shows that the total Real of cost estimation of Rp13.136.571.631,44 with the duration of work based on an analysis of daily reports and weekly reports for 155 working days starting on January 6th, 2021 until May 21st, 2021.  The use of Tekla Structures supports accurate modeling and work volume calculations, helping streamline budgeting and scheduling processes. The use of Building Information Modeling (BIM) in construction projects significantly accelerates the scheduling and cost estimation process even though certain limitations must be considered during project planning and execution.
