Abstract

Climate change and the increasing frequency of natural hazards pose growing challenges to the resilience of critical infrastructure. Yet, climate and disaster risks are commonly assessed in isolation, limiting their effectiveness for infrastructure planning. This fragmented approach limits civil engineering practice's ability to capture risk interactions, cascading effects, and spatial variability across interconnected infrastructure systems. This study aimed to develop an integrated risk analysis model that simultaneously incorporates climate change and disaster risks to support critical infrastructure resilience planning. A mixed-methods approach was applied using a case study in Masbagik and Pringgasela Districts, East Lombok Regency, Indonesia. The analysis combined risk matrix assessment, GIS-based exposure analysis, and multi-criteria decision analysis (MCDA) using climate data, disaster records, spatial datasets, and inventories of five critical infrastructure sectors. The results showed integrated risk index values ranging from 0.67 to 0.83, with water supply, drainage, and road infrastructure consistently identified as the most critical systems. Scenario-based mitigation simulations indicated potential risk reductions of up to 40% at the district level, while integrated assessment reduced estimated annual losses by approximately 34% compared to separated analyses. The findings demonstrate that climate and disaster risks interact through reinforcing, cascading, and cumulative mechanisms that materially shape infrastructure vulnerability. This study contributes an Integrated Climate–Disaster Risk Framework that advances infrastructure resilience theory, strengthens integrated risk management, and provides a practical, spatially explicit decision-support tool for resilient and sustainable infrastructure planning

Abstract

This study is aimed to examine thoroughly lontar Asta Kosala Kosali and Asta Bumi in regard to ashta or eight sectors of geometric pattern as devoted to Dewata Nawa Sangha. Several Balinese homes are studied especially during ritual ceremony yadnya as empirical field work, in order to combine with textual lontar content. Lontar asta kosala kosali describe that the four sides of the proposed home yard required to be divided by nine in the same size section. This technic will draw one square in the center and eight surrounding squares and provide the most practical way to draw eight surrounding sectors in a circle. Any space or point in any eight sectors in the space pattern will be located easily by constructing longitude and latitude across the center. This study revealed that this technic may establish various number of lay-out, resulting in space thrifty that promote psychological well-being thrive happy, calm, no angry in designing Balinese home in pursuing Dewata Nawa Sangha and the teaching of dharma ning asta kosala kosali and asta bumi.

Abstract

This study examines the implementation of Community Based Contracting (CBC) in a school infrastructure revitalization program in Bangli Regency. It aims to evaluate how the self-managed construction scheme impacts financial optimization, social participation, and managerial dynamics. Using a qualitative descriptive approach with case studies of two different schools, the study highlights the application of Value Engineering (VE) principles through the Contract Change Order (CCO) instrument. It found that the CBC method provided significant budget flexibility without changing the final nominal value of the work. Overruns on structural and architectural items were successfully rationalized, allowing for the reallocation of funds amounting to 12.42% to 19% of the contract value. Beyond technical efficiency, the CBC approach can foster a sense of ownership among stakeholders through their participation in design decision making and stimulate the local economy by leveraging local labor and material supply chains. However, the study found operational challenges, particularly the excessive workload experienced by teachers due to their dual roles as educators and project managers, in addition to the complexity of construction tax administration. Ultimately, this study concludes that although CBC is highly effective for holistic budget and facility optimization, further intensive technical and administrative assistance is needed to ensure that the primary tasks of educators in schools are not disrupted.

Abstract

Confined masonry structures are widely used in simple buildings located in seismic regions; however, their behavior is difficult to represent numerically because masonry is heterogeneous and nonlinear. This study evaluates layered shell elements in SAP2000 for modeling the global response of confined masonry, analyzes the influence of material parameters, and compares a simple building model based on the guideline of the Ministry of Public Works and Housing of Indonesia (PUPR), hereafter referred to as CM, with an Earthquake Engineering Research Institute (EERI)-based modified model, hereafter referred to as CME. The CME model includes additional reinforcing columns and beams around wall openings. Validation was conducted using two-dimensional and three-dimensional models based on previous laboratory experiments. The investigated parameters include masonry compressive strength (f'm), masonry elastic modulus (Em), masonry shear modulus (Gm), and concrete compressive strength of confining elements (f'c). The results show that layered shell elements can represent the global response of confined masonry structures, particularly initial stiffness, lateral capacity, and stress concentration patterns, although the analysis was conducted using monotonic pushover loading. The sensitivity analysis indicates that the parameter influence, from the lowest to the highest, is f'c, f'm, Em, and Gm. In the application model, both CM and CME reach the Immediate Occupancy (IO) performance level. However, CME produces smaller drift, higher lateral capacity, and a more uniform wall stress distribution than CM. Therefore, the EERI-based modification can increase lateral capacity and control local damage in confined masonry structures.

Abstract

Structural design for multistory buildings must satisfy not only strength and safety requirements but also material efficiency to achieve cost-effective construction. This study aims to redesign the structural system of Building A of the Kiara Beach Front Apartment to obtain a more efficient design while maintaining structural performance and safety. The redesign was carried out using the Special Moment Resisting Frame (SMRF) system in accordance with the provisions of SNI 1726:2019, SNI 1727:2020, and SNI 2847:2019. A three-dimensional structural model was developed in SAP2000, followed by analyses of gravity and seismic loads, inter-story drift, structural irregularities, and the design of beams, columns, slabs, and foundations. The results indicate that the redesigned structure satisfies seismic performance requirements, with the fundamental period and inter-story drift remaining within the allowable limits specified by the applicable standards. Furthermore, the optimization of structural member dimensions and reinforcement improved material efficiency in the first-floor structural elements, resulting in an 11% reduction in concrete volume and a 23% reduction in reinforcement weight. Consequently, a more economical structural design was achieved without compromising structural safety requirements.
