Abstract

Yogyakarta city is one of the earthquake prone areas in Indonesia that has historical buildings, high-rise buildings, road structures and bridges. The soil profile affects the amplification from bedrock to the ground surface. The bedrock acceleration is taken from the matched design response spectrum SNI by means SeismoMatch. The output of the NERA software shows that the ground acceleration is increasing from 0,249 g to 0,385 g or about 1,5 times compared to bedrock. The SAP2000v14 is used as dynamic analysis software. The modal analysis result that the 7 modes are enough for the analysis, so that it meets the mass participation ratio requirements in article 7.9.1 SNI-1726-2012 which is ≥ 90%. The results of dynamic earthquake analysis by both Time History and Response Spectrum analysis have relatively the same results in displacement, axial force and bending moment. In the Modal Time History 1 (MHIST 1) the large time interval affects the bending moment. After the small-time interval is used, both Modal Time History 2 (MHIST 2) and Direct Integration Time History (DHIST 2) give the same results.

Abstract

Semarang is the capital of Central Java Province located on the northern side of Java Island, directly adjacent to the Java Sea. Morphologically, Semarang is divided into two parts: upper Semarang and lower Semarang. Upper Semarang has a relatively steeper slope profile, while lower Semarang has a flatter topography. In terms of geology, upper Semarang has a rock composition in the form of volcano breccia and sandstone of Quaternary age, while in the northern part the contours tend to be flatter and the rocks are composed of breccia covered by thick alluvial. Semarang is also surrounded by three active faults (Semarang Fault, Kendeng Fault, and Lasem Fault). An earthquake with a scale of M 5.6 occurred in Semarang in 1856, allegedly due to the activity of the three faults. Based on the data of the largest earthquake that ever occurred and the N-SPT and Bore Log taken at the research site, the potential for liquefaction in the area was found to be up to 20 m deep. Low potential for liquefaction is found at depths of 8 to 18 m, while for depths of 18 to 20 m the potential is very low. High potential is found at depths up to 8 m. Of the 8 meters with high potential for liquefaction, the saturated silty sand layer at a depth of 6 to 8 m is the segment with the highest potential for liquefaction.

Abstract

The Rotiklot Dam Catchment Area is located in Belu Regency, East Nusa Tenggara Province. This research aims to forecast the rates of erosion and sedimentation utilizing the Soil and Water Assessment Tool (SWAT) method, as well as to assess the levels of erosion hazard present. According to the modeling outcomes, the average annual erosion rate within the Rotiklot Dam Catchment Area is calculated to be 18.5 tons/ha/year. The erosion hazard assessment indicates that the land within the Rotiklot Catchment Area is classified into two categories of erosion hazard levels: moderate and severe. Specifically, the area classified as having a moderate erosion hazard level encompasses 549.55 hectares, while the area categorized as having a severe erosion hazard level covers 587.55 hectares. The modeling results indicate that the average annual sediment discharge at the outlet of the catchment area leading to the dam is 1,865.75 tons per year. Over the course of the 28-year simulation period, the cumulative sediment total amounts to 106,317.1 tons.

Abstract

South Kalimantan has a tropical climate with high rainfall and high humidity. The weather in this area can also change rapidly, with strong winds and heavy rain, potentially damaging buildings and infrastructure. In recent decades, there have been significant improvements in building design and construction, especially in terms of strength and safety. However, many buildings are still vulnerable to wind damage, especially in areas prone to storms or strong winds. This research aims to simulate the effect of wind on a simple residential building in South Kalimantan measuring 6.0 m x 6.0 m, with varying roof slope angles of 15, 30, 35, and 40 degrees, using Thunderhead Pyrosim Software Version 6.9.1 (Academic License).. Based on the results of this study, it can be known that according to online BMKG data, the maximum wind speed that occurs in South Kalimantan is 21 m/det, and based on the results of software simulation, it can be known that the greater the slope angle of the roof, the greater the Cd (drag coefficient) / resistance of the building, which means that the building will have a higher possibility of being carried away by the wind. Conversely, a lower drag coefficient value indicates that the roof will be more resistant to wind flow pressure, or in other words, more aerodynamic, so that houses in windy areas can use roofs with a small slope angle (15o - 35o ) or concave roofs for better aerodynamics, and provide a barrier in the direction of the wind.

Abstract

Opra City Housing, located in Menganti District, Gresik Regency, is a residential area that is vulnerable to waterlogging and flooding, particularly during the rainy season. This condition is mainly caused by high annual rainfall combined with a drainage system that has not been fully integrated or optimized. The study employs both hydrological and hydraulic analyses to provide solutions. Hydrological analysis is carried out to determine the design rainfall and to calculate the runoff discharge using the rational method, while hydraulic analysis is applied to define channel dimensions, the capacity of the retention pond, and the capacity of external drainage channels. Rainfall data were collected from several nearby rainfall stations and processed using the Thiessen polygon method. The design discharge was then calculated based on maximum rainfall intensity and surface runoff coefficients. The study results indicate a right-angled drainage network with a total runoff discharge of 4.517 m³/s. Prefabricated U-ditch sections are used as drainage channels, with the smallest dimensions of 0.3 × 0.2 m for tertiary channels and the largest dimensions of 2 × 1.4 m for primary channels. A retention pond measuring 80 × 80 × 1.5 m with a capacity of 9,600 m³ is also planned. Calculations show that the initial river discharge of 3.374 m³/s at a water level of 0.4 m increases to 7.891 m³/s after receiving runoff, while the river’s maximum capacity of 70.050 m³/s at a water level of 3 m ensures the flow remains safe. Overall, this drainage system is designed to effectively control runoff, reduce flood risk, and minimize environmental impacts on the surrounding area.

Abstract

Cost efficiency in small-scale housing projects remains a critical challenge in construction planning. This study introduces a novel integrative approach by combining a precision-based Pareto analysis with a multidimensional Value Index evaluation within the framework of Value Engineering (VE). A case study was conducted on a residential project by CV. Majas in Banjarmasin. Three dominant cost items—wall, concrete, and woodwork—were identified using a quantitative ΔC and ΔP formula, marking an advancement over conventional Pareto analysis. Alternative evaluations were based on five functional criteria: strength, weather resistance, aesthetics, ease of installation, and maintenance. Results indicate that VE implementation reduced total project costs by 3.08% without compromising quality or functionality. The most efficient alternatives included lightweight concrete blocks, ready-mix concrete K-225, and meranti wood. The key novelty lies in the measurable and function-oriented cost optimization model that combines quantitative cost classification with functional scoring, providing a more objective and applicable decision-making tool in construction cost management. These findings contribute to the development of more rational and replicable cost planning strategies for similar residential projects.

Abstract

The increase in building infrastructure development in an area is certainly unavoidable. Soil, which is an important part of infrastructure development, certainly has provisions as a requirement to be used as a loan or good bearing capacity to receive the load above it so that it can maintain the stability of the construction above it. Not all soils have a stable bearing capacity for the construction above it. Soil investigations need to be used to determine the bearing capacity of the soil, so that the type of building construction foundation can be determined appropriately according to the CPT test data. The research location is in the Kupang Regency area and consists of 7 data collection locations. Soil physical test data is classified by AASTHO method and CPT test data is classified by soil type using qr and Fr relationship graph according to Robertson and Campanella and soil consistency according to Terzaghi and Peck. Based on the CPT data, the appropriate depth and type of foundation are determined. The CPT test results were then analysed to obtain the Permitted Bearing Capacityand Foundation Bearing Capacity values for each point. The analysis results show that all 7 locations have a foundation depth of  ≥ 6 m and the appropriate foundation type is a mini pile foundation with a cylindrical size of Ø 0.50 m and a triangular size of 0.20 x 0.20 m.

Abstract

This study aims to design a two-story earthquake-resistant house in Padang City with reinforced concrete structural system for columns, beams and foundations, combined with prefabricated lightweight steel roof frame. The design procedure refers to SNI 1727 2020 for minimum loads, SNI 2847 2019 on requirements for reinforced concrete and SNI 1726 2020 on seismic design procedures for buildings. 3D model was developed using sap2000 application to obtain internal forces and support reactions of the building. The foundation design was analyzed by Terzhagi’s method with consideration of the local soil conditions. The result indicate that the designed structural elements meet the strength requirements for earthquake resistant house in Padang. The use of prefabricated light steel roof frame does not significantly affect the total structural weight, but contributes to time efficiency during construction. The structural DED produced in this study is expected to serve as a practical reference for earthquake- resistant housing development in Padang. This research highlights the importance of applying seismic standards even to residential buildings.

Abstract

Ottawa sand has long been used as a standard material in geotechnical laboratory tests, particularly in grain size distribution and Sand Cone tests, due to its uniform particle size, purity, and stable physical properties. This study explores the potential of using beach sand from Nirwana and Mandeh as substitutes for Ottawa sand. The research process began with problem identification, followed by a literature review, sample collection, laboratory testing, and data analysis. The results show that the specific gravity of Nirwana sand (2.77) and Mandeh sand (2.72) are relatively close to Ottawa sand (±2.65). In terms of the coefficient of uniformity (Cu), Nirwana sand (2.34) is closer to Ottawa sand (2.17) compared to Mandeh sand (2.94). Regarding the coefficient of curvature (Cc), Nirwana sand (0.72) performs better than Mandeh sand (0.66), although both remain below the ideal range (1–3). Overall, Nirwana sand demonstrates greater potential as an alternative to Ottawa sand, with improvements in gradation recommended to achieve optimal performance.

Abstract

The Manguharjo Bridge has a traffic width of 6.50 m (two lanes in two directions) and is prone to congestion due to high traffic flow and limited road capacity. Congestion causes economic losses, environmental pollution, and energy waste. The Madiun City Government has proposed widening the bridge to address these issues. Based on this overview, a study is needed to assess the economic benefits of the Manguharjo Bridge widening plan. This research uses a quantitative methodology to analyze the benefits of widening the Manguharjo Bridge with two alternative lane widths over the bridge's 75-year lifespan. Primary data includes geometric surveys, traffic volume, and land use. Secondary data includes vehicle growth, time value, and vehicle component prices. Traffic performance analysis uses PKJI 2023, traffic forecasting, Vehicle Operating Cost and time value savings to evaluate the project's benefits. Based on the analysis results, Alternative 1 yields Vehicle Operating Cost savings of IDR 1,504,929,465,276 and time value savings of IDR 8,672,188,817,959. Alternative 2 achieved Vehicle Operating Cost savings of Rp3,903,545,756,479 and time value savings of Rp9,852,675,485,931. The results of the above analysis show that Alternatives 1 and 2 have good economic efficiency, which will be used for evaluation in determining the width of the traffic lanes on the Manguharjo Bridge.
