Abstract

The city of Denpasar has experienced rapid urbanization, necessitating improvements in infrastructure. One such infrastructure project is located in the Simpang Sanur–Tohpati area of Denpasar City. The success of this drainage project is crucial in addressing the recurring flood problems that threaten the city annually. This study aims to analyze the key determinants of project success in the drainage management initiative in the Simpang Sanur–Tohpati area. A quantitative approach was employed, using multiple linear regression analysis to examine the relationship between independent variables and the dependent variable. Primary data were collected through questionnaires distributed to respondents from the Denpasar City Government, contractors, and consultants directly involved in the implementation of the project. The findings indicate that cost, time, quality, and occupational health and safety (OHS) have a significant influence on project success. Notably, the study highlights the need to pay particular attention to OHS implementation, even though its statistical contribution is relatively smaller compared to the other factors. This research contributes to a better understanding among stakeholders of the importance of each factor in determining project success. It underscores the need for thorough project planning, emphasizing that cost, time, quality, and the implementation of OHS are critical factors that significantly influence the success of future projects.

Abstract

Labuhan Haji is one of the fishing villages characterized by a low standard of living among its residents. The economic conditions of the fishing community are concerning, despite the logical assumption that various means. In addition to working as fishermen, many also engage in agricultureal labor or small-scale trading. However, these alternative occupations are not always located within the village or in nearby areas, which results in diverse spatial requirements. This study aims to examine the relationship between the development of livelihood strategies among the fishing community and their impact on the spatial pattern of the village. A mixed-methods approach was employed, combining quantitative analysis using a spatial approach focused on human activities. The scoring results indicate that the agricultural sector received the higest score, totaling 1,090 with an average of 77.85%. correlation anlysis further reveals that the fuctional relationship between agriculture and spatial pattern variables yielded a correlation score of 9, indicating a strong correlation with variables such as transportation routes, physical form, and the distribution of facilities.

Abstract

The modernization of irrigation networks is a vital effort to improve the efficiency and effectiveness of water distribution for agriculture. This activity also represents the implementation of the government’s Asta Cita program in the context of national food security. One critical component of this process is excavation work, which significantly influences the success of such projects. This study aims to evaluate the accuracy of several interpolation methods in calculating excavation volumes based on design data, compared to existing conditions, using a tolerance threshold of 2.78%. The analysis indicates that interpolation methods produce varying results. The Kriging method shows a deviation of 2.30%, and the Surface to Surface (TIN) method shows a deviation of only 0.02%, both of which fall within acceptable deviation limits. These two methods also demonstrate high consistency and optimal accuracy for volume estimation. In contrast, methods such as Natural Neighbor (18.89%) and Radial Basis Function (RBF) (46.17%) result in significant deviations, indicating overestimation or underestimation that affects volume accuracy. Therefore, methods like Kriging and TIN, which meet the tolerance limits, are recommended for more accurate and efficient volume calculations in construction and topographic mapping activities.

Abstract

This study aims to determine the fire resistance of steel materials and analyze the type and thickness of fireproofing systems on the fire resistance of steel structures in high-rise buildings and modules in the oil & gas sector. The main problem to be solved is how this fireproofing system can extend the time of steel resistance to high temperatures before experiencing structural failure and can provide evacuation time. This study uses a quantitative approach with a post-test-only control group experimental design. The research sample consists of steel specimens coated with two types of protective materials, namely intumescent fireproofing and cementitious fireproofing with three different thicknesses (10 mm, 20 mm, and 30 mm). Data collection was carried out through direct testing of resistance time, temperature increase, and structural changes in the steel material. The test results show that steel specimens without fireproofing will experience structural failure in approximately 60 minutes. Meanwhile, steel coated with a 30 mm thick intumescent fireproofing layer can last up to 120 minutes, while a 30 mm thick cementitious fireproofing layer shows the same resistance as intumescent. Quadratic regression analysis and Fourier conduction law show a positive relationship between increasing coating thickness and fire-resistant time. This study concludes that the implementation of appropriate fire-resistance systems can improve the durability of steel in high-rise buildings and oil and gas modules, extend evacuation times, and reduce the risk of structural collapse. These findings significantly contribute to fire safety policy and fire-resistant building design practices.

Abstract

The Office Building of the Bengkulu National Road Implementation Agency (BPJN) is designed to function as a central facility for the planning, procurement, construction, and maintenance of road and bridge infrastructure. This two-story building is planned to reach a total height of 11.563 meters. Unlike conventional buildings, it features a distinctive architectural design with an oval floor plan, resulting in an unconventional structural configuration. The structural works encompass the design of key components including floor slabs, beams, columns, shear walls, and the foundation system. For the superstructure, a Special Moment Resisting Frame System (SMRFS) was selected, as it is suitable for regions with high seismic risk (seismic design categories D, E, and F). This study aims to assess the structural performance of the building using the response spectrum analysis method in accordance with SNI 1726:2019. The research methodology was carried out in several stages, including data collection from both field observations and supporting documents, structural modeling, load analysis, structural analysis, and evaluation of structural performance. The structural model was developed based on official design drawings. The loads considered in the analysis include both gravity and lateral loads. The results showed that mass participation exceeded 90%, and both the structural period and base shear values complied with the criteria set by SNI 1726:2019. The inter-story drift results were within the allowable limits, indicating that the building is structurally stable. Based on the calculated drift ratio, the building's performance level falls under the Immediate Occupancy (IO) category.

Abstract

The conversion of catchment areas into built-up land has increased surface runoff and reduced natural river storage capacity, thereby elevating flood risk, particularly during high rainfall events. One area that frequently experiences flooding is Sekip Kadipiro, located within the Pepe Baru Sub-watershed of the Pepe Watershed system in Surakarta City. The hydrological connection of this area to the Pepe Watershed makes it highly vulnerable to flooding. In January 2023, heavy rainfall caused inundation affecting approximately six residential houses in Sekip Kadipiro. This study aimed to determine the 20-year return period design flood discharge and to simulate flooding in the Sekip Kadipiro area using the HEC-RAS 4.1 application. The analysis utilized 17 years of rainfall data, physical characteristics of the Pepe Baru Sub-watershed, and river geometry data processed using QGIS 3.10. The 20-year design rainfall was calculated using the Log Pearson Type III method, resulting in a value of 359.422 mm. Hourly rainfall distribution was analyzed using the ABM method for a duration of four hours, while effective rainfall was determined using the SCS-CN method. The design flood discharge for the 20-year return period was estimated using the Nakayasu Synthetic Unit Hydrograph method, yielding a peak discharge of 1745.42 m³/s. Hydraulic simulation results from HEC-RAS 4.1 indicate that floodwater levels reach an average of 1.75 m above the embankment crest. This demonstrates that the existing river channel capacity is insufficient to convey the design flood discharge, resulting in overflow and a high potential for flooding in surrounding residential areas.

Abstract

The implementation of construction projects often faces delays that are difficult to avoid, as experienced in the construction of the City X Hospital Building, where there was a discrepancy between the initial plan and actual field implementation, resulting in a two-week delay in weekly progress. This study aims to analyze time and cost efficiency and compare the effectiveness of alternatives between extending working hours and adding labor using the Time Cost Trade Off method. This research is comparative, comparing the total cost and duration of the project for both acceleration alternatives. The total project cost under normal conditions was recorded at IDR 7,289,386,643.45 with a duration of 86 days until the completion of the third floor. The analysis shows that extending working hours by 1 to 4 hours resulted in costs of IDR 14,584,817,481; IDR 21,871,659,072; IDR 28,672,701,971; and IDR 34,564,808,294, with cost efficiency of –100.08%, –200.05%, –293.35%, and –374.18%, respectively. The project duration was reduced to 64, 50, 41, and 36 days, with time efficiency of 26%, 42%, 53%, and 58%. Meanwhile, the alternative of adding labor resulted in a total cost of IDR 13,660,989,499 with a cost efficiency of –87.41% and a project duration of 64 days (26% time efficiency). Based on these results, both extending working hours by one hour and adding labor showed the most efficient outcomes, but overall, adding labor was considered more optimal as it achieved the same acceleration with the lowest total cost.

Abstract

This study aims to analyze the effect of land use change on flood discharge in Batam City for the period 2014–2023 by integrating spatial analysis based on Geographic Information System (GIS) and hydrological analysis using the Rational Method. The data used included Landsat satellite images from 2014 and 2023, annual maximum rainfall data for 10 years, and data on the area of the river basin. Land use changes were analyzed through supervised classification and their contribution to changes in the runoff coefficient was calculated based on the area of each land class. The results of the study show a 10.86% reduction in forest area and a 4.50% increase in built-up land. These changes have resulted in an increase in the average runoff coefficient of the watershed, which in turn has increased the maximum planned flood discharge. The calculation results show an increase in average flood discharge of 11.89% or around 50.47 m³/second from 2014 to 2023. This study confirms that land use changes due to urbanization contribute significantly to an increased risk of flooding in Batam City, thus requiring sustainable spatial management.

Abstract

The Aceh Transportation Agency has introduced the Trans Koetaradja Feeder Bus as a public transportation facility for the community to reach residential areas or housing complexes. However, the Trans Koetaradja service still faces limitations in accessing settlements located in remote areas, making it difficult for residents to reach the available routes. To expand coverage to more evenly distributed residential areas, including remote regions, while simultaneously reducing passenger travel time to their destinations, the operation of Battery-Based Electric Motor Vehicles (KBLBB) is planned as a small-scale public transport mode. This study aims to identify the characteristics of travelers and the factors influencing preferences for using the Trans Koetaradja Feeder Bus and KBLBB through a Structural Equation Modeling (SEM) approach. Research data were obtained using the Stated Preference (SP) method by involving 200 respondents through questionnaire distribution. The questionnaires were distributed to Trans Koetaradja users and residents living around Feeder Route 7 (Masjid Raya Baiturrahman – Lambaro) via Lueng Bata. The results showed that accessibility was the most dominant factor influencing user preferences, reflecting public concerns about the considerable distance from homes to bus shelters/stops, which potentially causes delays in daily activities. Therefore, the community welcomed the presence of KBLBB as a solution. Furthermore, the SEM modeling results with Confirmatory Factor Analysis (CFA) produced a significant measurement model, in which the variable “accessibility” was proven to influence “comfort.” Indicators within the “accessibility” construct were identified as the main factors contributing to users’ perception of comfort.

Abstract

Batam City with existing drainage issues is a major hindrance to its performance. Road construction is always related to drainage funcitionality. The existing condition, with heavily piled-up sediments, causes a significant issue for Batam, Nagoya, and Batam Kota sub–district. Sediment accumulation in the drainage base depth causes a reduction in drainage volume, resulting in backflow and disturbance of water flow dynamics. This slowly erupts to the surface and cause flooding in roadways. Flooding roadways cause traffic congestion, erosion of the road structure, and accumulation of sediments due to the intensity of rainfall. Which resulting damages to drainage system. By installing sediment traps on manholes and lower base drainage, it can help reduce the buildup of sediments on the drainage base. Which will reduce flood risk and allow water to flow smoothly without resulting in backflow.
