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 occurrence of large-scale earthquakes in Indonesia is still one of the phenomena that often occurs, this can cause damage to buildings, so applying standardization of earthquake-resistant buildings during construction is necessary. This study review was carried out on Graha Sepuluh Nopember building using evaluation method to earthquake-resistant buildings regulated in Indonesian Earthquake Hazard Deaggregation Map (Pusgen, 2022). The model was evaluated using nonlinear time history analysis in order to obtain behavior in post-elastic conditions. The result of this research uses parameters of displacement and plastic hinge, indicates that the building has immediate occupancy performance level means that the building structure is safe, structural failure is not significantly damaged and can be used again immediately.Keywords  Nonlinear time history analysis, Indonesian earthquake hazard deaggregation map, earthquake-resistant building, ground motion
