Abstract

Penelitian ini menganalisis daya dukung aksial dan penurunan pondasi spun pile berdiameter 60 cm untuk Gedung Rawat Inap Tower-1 RS Haji Medan, menggunakan uji pembebanan statis (static load test) dan pemodelan elemen hingga (FEM) dengan PLAXIS 3D. Data lapangan dari Uji Penetrasi Standar (SPT) dan cyclic loading test dibandingkan dengan simulasi numerik menggunakan model Mohr-Coulomb dan Hardening Soil. Perhitungan empiris berbasis data SPT (metode O’Neil & Reese) menghasilkan kapasitas ultimit (Qult) 204,24 ton, sedangkan interpretasi uji pembebanan (metode Davisson, Mazurkiewicz, dan Chin) menunjukkan nilai lebih tinggi (390–476 ton), mengonfirmasi sifat konservatif prediksi berbasis SPT. Faktor keamanan (2,43–2,97) memenuhi standar ASTM D1143. Simulasi PLAXIS 3D secara akurat mereplikasi penurunan yang diukur di lapangan, dengan deviasi maksimal <5%. Model Hardening Soil memberikan kesesuaian lebih baik dengan hasil loading test (penurunan 6,66 mm pada beban 320 ton) dengan mempertimbangkan nonlinieritas tanah. Perhitungan penurunan elastis (2,1 mm untuk tiang tunggal; 5,9 mm untuk kelompok tiang) tetap dalam batas toleransi (25 mm). Rekomendasi meliputi optimasi panjang tiang berdasarkan stratigrafi SPT dan penggunaan model Hardening Soil untuk proyek dengan cyclic loads. Pendekatan terpadu ini meningkatkan desain pondasi dalam yang ekonomis dan aman untuk struktur bertingkat tinggi di wilayah perkotaan dengan keterbatasan lahan.

Abstract

Penelitian Pada analisis pondasi, besarnya daya dukung dan penurunan yang terjadi merupakan dua kriteria yang sangat penting. Pondasi wajib memiliki daya dukung yang mampu memikul beban diatasnya, sehingga sistem tranfer beban ke tanah dapat berjalan dengan tetap mengontrol terhadap penurunan ijin untuk menjaga kestabilan konstruksi di atasnya. Analisis ini bermanfaat untuk menghitung besarnya daya dukung dan penurunan yang terjadi pada pondasi spun pile proyek Gedung Rawat Inap Tower-1 RS Haji Medan, secara empiris dengan metode elemen hingga menggunakan aplikasi PLAXIS 3D dengan jenis tanah Mohr-Coulomb dan Hardening Soil Dari analisis yang telah dilakukan, daya dukung ultimate spun pile berdasarkan data SPT dengan menggunakan persamaan O’Neil dan Reese adalah 165,42 ton sedangkan menggunakan hasil interpretasi loading test dengan metode Davisson memberikan nilai 330 ton, metode Mazurkiewich 430 ton dan metode Chin 380 ton. Untuk besar penurunan spun pile tunggal, secara analitis dengan hasil loading test Aksial di lapangan menghasilkan besar penurunan 8,45 mm, analisis berdasarkan FEM PLAXIS 3D Mohr-Coulomb besar penurunan 10,99 mm dan Hardening Soil besar penurunan 9,26 mm. Kesimpulan dari analisis bahwa nilai keamanan yang digunakan saat desain dan analisis penurunan yang paling mendekati hasil di lapangan adalah analisis dengan PLAXIS 3D dengan jenis permodelan Hardening Soil.

Abstract

Indonesia, as an agrarian country, heavily relies on the availability of water for irrigation, raw water supply, and electricity generation to support industrial growth. One of the government’s efforts to ensure water availability is the construction of dams, including the Cibeet Dam, which serves to reduce flooding, provide raw water, support irrigation, and generate electricity. A crucial component of a dam is the spillway, which must be capable of accommodating excess water, especially during extreme flood events. This study aims to re-evaluate the spillway design of the Cibeet Dam using a hydraulic and structural stability analysis approach. The data used includes the Cibeet Dam planning documents, topographic data, hydrological data, geotechnical data, soil investigation data, climatological data, and reservoir capacity data. The analysis covers stability against overturning, sliding, seepage, and soil bearing capacity under three water level conditions (empty, normal, flood), and assesses construction cost efficiency. The results show that reducing the spillway crest width by 0.5 m only increases the head (Hd) by 2 cm. The spillway with an ogee crest and USBR II stilling basin is considered stable, with safety factors >1.5 under normal conditions and >1.2 during seismic events. The soil bearing capacity is also deemed sufficient to support the structure under all water level conditions.

Abstract

The growth of commercial areas in urban areas, especially shopping centers, has contributed significantly to the increase in traffic volume. This study aims to analyze the influence of Royal Plaza visitor activities on traffic volume and degree of saturation on the Jalan Ahmad Yani network, Jalan Ketintang, and the Ahmad Yani-Ketintang intersection in Surabaya City. The method used refers to the Indonesian Road Capacity Guidelines (PKJI) 2023, with primary data collection through a traffic volume survey for four days in three time periods (day, evening, night), then analyzed to obtain capacity values, actual volume, and degree of saturation (DS) on each road segment. The results of the analysis show that the highest traffic volume was recorded at 5444.70 SMP/hour on Jalan Ahmad Yani, with a road capacity of 5115.64 SMP/hour, resulting in a degree of saturation (DS) value of 1.06. This value indicates that the level of road service is in category F, which reflects very saturated traffic conditions and congestion. Meanwhile, the Ahmad Yani–Ketintang intersection shows DS ranging from 0.85 to 1.19, depending on peak times. This finding confirms that the presence of Royal Plaza places a significant traffic burden on the surrounding road network, and a traffic management strategy is needed to mitigate the impact and improve road service performance.

Abstract

The development of technology has significantly influenced the construction industry, introducing innovations that enhance project execution efficiency and accuracy. One of the notable advancements is Building Information Modeling (BIM) is a digital representation of a building that fully illustrates its form, size, and functional aspectsThis study aims to implement Building Information Modeling (BIM) for Quantity Take Off (QTO) using Autodesk Revit 2025 and compare its results with conventional methods in terms of volume and cost estimation accuracy. The research object is the South Cross Road Construction Project (JLS) Lot 3 from Pantai Serang to Sumbersih. This comparative quantitative study utilizes Detail Engineering Design (DED) documents and 3D modeling with Autodesk Revit 2025. The findings show that BIM-based QTO produces more accurate and efficient cost estimations, especially in complex calculations such as cut and fill operations. The BIM method resulted in a total project cost that was 13.73% higher than the conventional method, primarily due to more precise terrain modeling. This research is expected to be a reference for improving the accuracy of infrastructure project cost estimation.

Abstract

Highways are vital infrastructure in supporting land transportation systems, community mobility, and logistics distribution. To ensure safety, comfort, and structural durability, highway pavement design must be based on appropriate technical standards. This study aims to analyze the quality components of rigid highway pavement based on vehicle volume using two methods: Pd T-14-2003 and SNI 8457:2017, with a case study on the pavement project of the Cimanying–Jipu highway section. Primary data was obtained through field observations, while secondary data was obtained from relevant agencies, including traffic volume, vehicle types, and projections of average daily traffic growth. Based on a subgrade CBR value of 26%, both methods resulted in a concrete layer thickness of 20 cm, with concrete quality K-175 (Pd T-14-2003) and K-225 (SNI 8457:2017). Detailed calculations show differences in reinforcement specifications between the two methods. The analysis results indicate that SNI 8457:2017 specifies smaller dowel dimensions but with closer installation spacing, while Pd T-14-2003 requires larger reinforcement dimensions. This study helps provide recommendations for selecting a more economical and effective rigid pavement design method based on traffic conditions and site characteristics.

Abstract

This study aims to analyze the economic feasibility of rigid pavement road construction through a comprehensive cost-benefit analysis using Net Present Value (NPV), Economic Rate of Return (ERR), and exponential methods, with a case study on the Cimanying-Jiput road section in Pandeglang, Banten.  This research employs a quantitative approach where data collection was conducted through field surveys to obtain primary data and documentation from relevant agencies to gather secondary data. The economic feasibility assessment uses NPV and ERR methods, where a project is considered economically feasible if it yields an NPV greater than zero and an ERR exceeding the Bank Indonesia discount rate of 4.60%. The calculation results show that the Net Present Value (NPV) is Rp. 5,687,857,786, and the Economic Rate of Return (ERR) is 15%. Both indicators demonstrate that the benefits generated exceed the costs incurred. Based on the cost-benefit analysis using NPV and ERR methods, the construction project for the Cimanying-Jiput road section is economically viable and recommended for implementation. The positive NPV and ERR values above the discount rate indicate that the project will generate substantial economic benefits for the community and transportation system in the region.

Abstract

Lampung Province, as the land gateway between Sumatra and Java, plays a vital role in Indonesia’s national road network. With 1,298 km of national roads managed by BPJN Lampung, the region supports high traffic from heavy vehicles. However, these roads face significant damage, primarily due to two factors: poor road management (including planning, execution, supervision, and maintenance) and the frequent passage of ODOL (Over Dimension Over Loading) vehicles. This study investigates the causes and key parameters of road damage in Lampung, aiming to identify the most dominant factors. Data were obtained from interviews, questionnaires, and road section records from relevant stakeholders and analyzed using the Analytic Hierarchy Process (AHP). The findings reveal that ODOL vehicles are the most significant cause of road damage, with a weight of 67%, while the International Roughness Index (IRI) emerged as the most critical parameter, holding a weight of 27%. These results underline the urgent need for tighter regulations on ODOL traffic and the prioritization of IRI as a core measure in assessing road quality. Enhancing monitoring and maintenance based on these insights is essential to improving road durability and ensuring sustainable transportation in Lampung Province.
