Abstract

This research explores the challenges of integrating spiritual and cultural values into public spaces and addressing environmental and social issues in Denpasar, a city under urbanization and mass tourism pressures. The study aims to explore innovative strategies for sustainable tourism in Denpasar through the concept of community-based placemaking, employing both top-down and bottom-up approaches to create meaningful spaces. A qualitative approach was used, with data collected through in-depth interviews, participatory observations, and document analysis, focusing on case studies in one traditional village in each of Denpasar’s four districts. The research highlights the role of local communities, cultural integration, and environmental sustainability. Findings reveal that the bottom-up approach in placemaking enhances community engagement and cultural authenticity, while the top-down approach, although efficient, requires better integration of local values. The study concludes that a collaborative framework involving local communities, the government, and the private sector is essential for creating sustainable tourism destinations. This research contributes to the field by offering practical strategies for culturally and environmentally sensitive placemaking, particularly in urban contexts.

Abstract

The majority of building and civil engineering projects start on undeveloped soils. Before taking any further action, a thorough site inspection is required to determine the current condition of the site. Finding a location with optimal soil conditions can be difficult. One of the most commonly used methods for treating undeveloped soil is to incorporate natural fiber to reinforce soil, also known as natural fiber-reinforced soil. The purpose of this review article is to look at how different natural fibers reinforced soil. A review of studies suggests that reinforcing soil with natural fibers is a low-cost and effective stabilizing technique with several benefits. This paper is intended for geotechnical engineers in improving undeveloped soils with natural fibers, as well as researchers conducting future research.

Abstract

Peat soil is a unique type of soft soil that has a low bearing capacity and experiences significant creep effect. This inherent challenge necessitates effective improvement methods to enhance its stability, among which helical pile foundations stand out as a viable solution. Despite their promising application, the nuances of how creep influences the performance of these helical piles in peat soil remain largely unexplored. This study aims to analyse the effect of creep on the settlement and failure pattern of helical pile foundations in peat soils. Axis-symmetric two-dimensional numerical analyses using the finite element method were carried out to model helical piles foundations with varying creep indices (Cα) and differing spacings between the helical plates (1D and 3,5D). The results showed that the effect of creep caused the settlement of helical piles to increase as the value of Cα increases. However, the changes of excess pore water pressure around the helical pile foundation were not significantly affected by the variation of Cα value. In addition, the failure patterns of helical piles foundations were not affected by the creep effect, with the failure mechanism still following the cylindrical shear pattern for the 1D inter-plate spacing and the individual bearing pattern for the 3,5D inter-plate spacing. This study provides insight into the importance of considering the effect of creep in the design of helical piles foundations in peat soils for long term use.

Abstract

Flooding is one of the problems in Pangkal Pinang City. Tin mining activities in the districts around Pangkal Pinang City have triggered flooding in Pangkal Pinang City Apart from that, the reduction in catchment areas and sub-optimal polder system infrastructure affect the height and duration of flood inundation in Pangkal Pinang City. Flood management is currently still partial, so it is necessary to carry out integrated coordination between agencies and institutions to review the master plan for flood management in Pangkal Pinang City. To prevent flooding, it is necessary to review the things that cause flooding, so research needs to be carried out to analyze these things. This research aims to determine and analyze the influence of mining activity factors, catchment areas, polder systems and coordination on flood conditions in Pangkal Pinang City. This research uses a multiple linear regression analysis model with supporting data from historical data on the height and average duration of flood inundation in Pangkal Pinang City. The research results showed that the model equation Y = 3.216 + 0.484X1 – 0.396X2 – 0.412X3 – 0.480X4. Based on the results of data analysis using SPSS, the results showed that mining activity factors, catchment areas, polder systems and coordination had an influence on flood conditions in Pangkal Pinang City with an influence contribution of 85.0% with the most dominant variable ranking influencing flooding, namely mining activity. The regression coefficient value for the mining activity variable has a positive value of 0.484. This shows that if mining activity increases by 1%, then the height and duration of flooding as a flood indicator will increase by 0.484 times assuming other independent variables are considered constant. This model is used to project future floods. With this modeling, it is hoped that it can be used to overcome flooding in Pangkal Pinang City.

Abstract

The construction of the Green Campus of Sentul Defense University has suffered a setback from the planned schedule. In its planning, this project will be carried out for 5 months from May 2024 to September 2024, but it was delayed due to foundation work.  The bore pile foundation work itself was carried out for 70 days from the 5th week to the 14th week.  The bore pile work was planned to start in the 5th week, but in its implementation, it was only done in the 10th week, so it is necessary to identify the factors causing the delay and assess the level of importance. Therefore, this study aims to rank the factors that cause delays in bore pile work using the Relative Importance Index (RII). The variables consist of Owner (X1), Consultant (X2), Contractor (X3), Environment and K3 (X4), Materials and Equipment (X5), Construction Management (X6). The research method used is quantitative survey with descriptive analysis. The results of the analysis and calculation of the RII are the dominant factor causing the delay in bore pile work based on the variable is Owner (X1). Meanwhile, the dominant factor causing delays in bore pile work based on indicators is the Owner's delay in the approval process and making design changes (X1.2). The results of this study are expected to be a reference in the next bore pile work in the green campus project.

Abstract

Understanding the hysteresis behavior of reinforced concrete (RC) beam-column joints with monolithic slabs under cyclic loading is essential for assessing seismic performance. Finite element analysis (FEA) provides a powerful tool for such studies, but accurately capturing cyclic response remains challenging. This research aims to develop and validate an FEA model that provides the hysteresis behavior of an RC beam-column joint focusing on material modeling approaches and emphasizing the influence of discrete crack modeling in simulating major crack opening and closure. The numerical model is implemented in ABAQUS/Standard, combining the Concrete Damaged Plasticity (CDP) model for concrete, combined hardening for reinforcement, and discrete crack representation to enhance crack behavior simulation. The model is validated against previous experimental results by Durrani & Zerbe (1987) under the same cyclic loading protocol. The results show that least one discrete crack significantly enhances the agreement between numerical and experimental hysteresis loops, while two discrete cracks provide the best match for capturing pinching effect and cyclic stiffness degradation. The compression stiffness recovery parameter (wc) in CDP and the combined hardening model for reinforcement also play critical roles in influencing numerical results. The model successfully reproduces cyclic stiffness degradation and energy dissipation, although minor discrepancies exist due to material data limitations. This study advances numerical modeling of RC beam-column joints under cyclic loading, emphasizing the importance of discrete crack modeling in enhancing simulation accuracy for seismic performance assessment.
