Abstract

The demand for property, including houses, continues to grow rapidly in Indonesia. The housing price prediction is essential in assisting the stakeholders such as buyers, sellers, and investors to make better decision-making. There are many key factors that influencing the housing prices and it is challenging to identify the most relevant factors. This study provides a comparative analysis of various methods in the housing price prediction that consists of one traditional method, Linear Regression (LR), and three artificial intelligence (AI) methods, including Artificial Neural Network (ANN), Classification and Regression Tree (CART), and Chi-Squared Automatic Interaction Detection (CHAID). The aim is to find the best machine learning method in predicting the housing price in terms of prediction accuracy through the four performance indicators and one combined performance index called the reference index (RI). The main findings of this study is that the AI-based method, the ANN method, has the best accuracy indicated by its highest RI value hence outperforming other methods in predicting the housing prices.

Abstract

The warehouse frame is a specialized steel structure requiring more complexcalculations than standard portal frames. This study investigates the impact ofrafter angle and span length on ductility and stability. Results indicate thatincreasing span length enhances ductility but reduces stability due to higher storydrift. For example, M1 (10-meter span) shows a ductility of 4.62 and story drift of13.64 mm, while M3 (20-meter span) achieves 5.07 (+9.62%) with a drift of 46.77mm. A larger rafter angle slightly increases ductility but decreases stability. M1 (10°angle) records 4.62 ductility and 13.64 mm drift, whereas M7 (20° angle) reaches4.71 (+1.79%) with 16.92 mm drift. Higher structure stiffness reduces ductility butboosts stability. M3 (128.29 kN/m stiffness) shows 5.07 ductility and 46.77 mmdrift, while M12 (192.67 kN/m) records 4.96 (-2.17%) with 29.68 mm drift. DespiteM12's minor ductility reduction, M3 demonstrates better elastic-plastic behavior.These findings reveal a clear polarity between ductility and stability

Abstract

The sedimentation and erosion of Manikin Estuary is analysed using numerical model DELFT3D. The model simulates the influence of river flow and coastal wave to induce the transport of sediment. The river flow is obtained from automatic water level data and suspended sediment is measured on site. The wave is hindcasted using spectral wave model SWAN with forcing from ERA 5 Reanalysis Data. The model is calibrated by comparing the coastline change from the model and satellite imagery. The simulation scenarios consider the combination of river discharge and waves condition in east season and west season. The simulation shows in the west season the dominant influence from high waves produces considerable erosion and sedimentation in the estuary and coastal areas, while high river discharge during the wet season has more influence on sedimentation and erosion in the river. Meanwhile, in the east season, the dominant influence from waves results in sedimentation and erosion that predominantly occurs in coastal areas even though the waves are relatively lower than the west season.

Abstract

Currently, the implementation of turnkey contracts has recently gained significant attention due to several advantages, such as shorter construction durations, improved construction quality, and reduced overall project costs. However, compared to the traditional Design-Bid-Build (DBB) method, the higher degree of uncertainty in turnkey projects introduces substantial risks, particularly for contractors. Project success in the construction industry is commonly evaluated based on cost performance relative to the planned budget. This study aims to identify and analyze the key variables influencing cost performance in toll road projects delivered through turnkey contracts. A quantitative research approach was applied using Structural Equation Modeling (SEM) with Partial Least Squares (PLS).The study involved 60 respondents representing service providers, ranging from general managers to administrative staff, who were directly engaged in toll road projects using turnkey contracts. Data were collected through structured questionnaires and interviews. The results indicate that contract conditions have the most significant positive impact on cost performance, with a path coefficient of 0.421, influenced by the field conditions variable. Variations in contract conditions or Contract Change Orders (CCOs) were found to significantly affect cost performance. Therefore, identifying potential risks to field conditions and conducting detailed field investigations are critical to maintaining cost control and ensuring project success.

Abstract

Cement Treated Sand (CTS) plays a pivotal role in enhancing poorly graded sandy soils, which inherently lack cohesion and pose challenges for infrastructure development. This study investigates the influence of varying cement percentages (6%, 8%, 10%, and 12% by dry weight of sand) on the mechanical properties of CTS. Tests were conducted for Unconfined Compression Strength (UCS) and California Bearing Ratio (CBR) to evaluate compressive strength and soil bearing capacity, respectively. The findings demonstrate that increasing cement content improves compressive strength but may diminish ductility. Therefore, optimizing cement ratios is essential to strike a balance between strength enhancement and material durability. This research underscores the critical role of CTS in stabilizing poorly graded sandy soils, offering valuable insights for enhancing infrastructure resilience in coastal areas prone to these soil types.

Abstract

The construction industry in Indonesia contributes significantly to the economy, but lags behind in technology adoption and faces environmental challenges. Lean Construction offers a solution by improving efficiency through waste reduction and value addition, although its application is still limited due to work culture resistance and low priority. This study aims to identify the factors that affect the success of lean implementation in East Java using SEM-PLS surveys and analysis. The results showed that organizational policies had a significant influence (46.2%), followed by teamwork (29.6%) and leadership (23.9%). Leadership is influenced by manpower and resources (71.1%), while organizational policies are influenced by optimization (88.7%). However, some variables, such as manpower vs. teamwork and optimization vs. leadership, don't have a significant influence. This study provides strategic insights to support the effective implementation of Lean Construction to improve the performance of the construction industry in Indonesia.

Abstract

superior mechanical performance and long-term durability; yet, its pervasive usage adds to resource depletion and considerable environmental impacts, mainly from cement manufacturing and aggregate extraction. To address these problems, this study studies the inclusion of ceramic waste as a sustainable alternative to natural aggregates in concrete. The purpose was to examine the impact of ceramic waste on workability, compressive strength, and split tensile strength. A total of sixteen concrete mixes were made, comprising one control mix and fifteen mixes with different quantities of ceramic waste as fine and coarse aggregate replacements. The mix design followed a ratio of 1:1.67:2.81 with a water-to-cement ratio of 0.50, targeting a 28-day compressive strength of 20 MPa. Workability was examined using the slump test, while compressive and split tensile strengths were recorded at 7 and 28 days in line with ASTM standards. The experimental data show that partial replacement of fine aggregates at 10–20% and coarse aggregates at around 10% gave optimal mechanical performance, with strength values similar to or above those of the control mix. Higher substitution levels resulted in losses in both workability and strength due to increased porosity and poorer bonding within the interfacial transition zone. Beyond technical performance, the study indicates that mixing ceramic waste into concrete minimizes landfill disposal and conserves natural resources, consistent with circular economy concepts. These results emphasize the potential of ceramic waste as a viable and eco-efficient material for sustainable concrete manufacturing.

Abstract

Palu is one of the regions with high seismicity due to its location directly on the Palu-Koro Fault, the longest active fault in Indonesia. A post-earthquake structural response evaluation was conducted on a reinforced concrete office building in Palu, Indonesia, using nonlinear time-history analysis to assess its performance under seven recorded ground motions. This evaluation serves as a reference for determining the structural functionality, safety against collapse, and the need for structural reinforcement due to earthquake loads. The primary focus was to assess the serviceability limit state and ultimate limit state in accordance with SNI 1726:2019 and to determine the performance level category based on ATC-40. Modeling was conducted using ETABS software with input from earthquake accelerograms of the Superstition Hills, San Fernando, Kobe, Loma Prieta, El Centro, Caldiran, and Manjil earthquakes. The results show significant variations among the earthquake scenarios. The highest displacement and drift values occurred in the Y-direction due to the El Centro earthquake, while the lowest values were observed in the X-direction during the Caldiran earthquake. Only the Caldiran earthquake met the limit criteria in both directions. Based on ATC-40, three earthquakes (Caldiran, Loma Prieta, and San Fernando) reached the Immediate Occupancy (IO) and Life Safety (LS) levels. In comparison, the other four earthquakes showed levels exceeding Collapse Prevention (>CP), indicating potential building failure and high hazard risks. Therefore, further evaluation and retrofit recommendations are necessary to enhance the structure's capacity and stiffness, thereby achieving the desired performance level in all earthquake scenarios.
