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.

Abstract

Stabilization is the mixing of soil with other materials, one of which is polyacrylamide (PAM) synthetic polymer. Subgrade stabilization was carried out on local soil at Jalan Cisasawi, Desa Cihanjuang with the percentage of PAM addition of 4%, 6%, 8%, 10%, and 12% of soil weight. This is done to get a high CBR value. In laboratory tests, PAM was shown to increase the bearing capacity of the soil to the optimum at 8% PAM content from dry weight. At 10% and 12% PAM percentages, the soil experienced a decrease in bearing capacity because it was no longer able to accept other substances from outside. CBR testing with 8% PAM content resulted in a soaked CBR value of 16.4% and an unsoaked CBR of 20.5%. In the Free Compressive Strength test with 4% PAM content, PAM can increase the compressive strength value by 162%, 6% PAM by 207% and 8% PAM by 226% of the original soil compressive strength. It was also calculated the unit price of mixing PAM with soil per 1 m3 as a reference for making a cost budget plan, it was proven that the unit price increased as the percentage of PAM increased.

Abstract

Roads must have safety and comfort, which can be seen through the condition of the pavement. A good pavement is influenced by a good bearing capacity of the subgrade. Not infrequently, road damage that occurs is caused by a lack of bearing capacity of the subgrade (CBR<6). One way to improve the bearing capacity of the subgrade is to stabilize it with polyacrylamide (PAM) synthetic polymer. Subgrade stabilization was carried out on local soil at Jalan Cisasawi, Desa Cihanjuang with a percentage of 4%, 6%, 8%, 10%, and 12% of the dry soil weight. From the results of laboratory CBR testing, calculations were made to determine the effect on the thickness of flexible pavement using the SKBI 1987 method. After the calculation, it can be concluded that the CBR value affects the thickness of the flexible pavement layer. The greater the subgrade CBR value, the thinner the pavement thickness (with 8% polyacrylamide). This has been proven in the calculation where PAM managed to increase the bearing capacity of the soil to the maximum at 8% PAM content (soaked CBR 16.4% and unsoaked CBR 20.5%) and the thickness of the lower foundation layer is 25 cm (the thinnest among other levels).
