This study aims to analyze the application of Value Engineering (VE) as a systematic approach to reduce the overall budget of a 12-story university building project with a total floor area of 24,000 m² and a budget of IDR 164,668,171,695. The research focuses on the structural works, particularly the floor slab component, which is considered to have the highest potential for savings without compromising the integrity of the main structural system. The methodology involves project document analysis, interviews, and evaluation of VE-based alternative designs. The findings reveal that substituting the conventional reinforced concrete slab with a Hollow Core Slab (HCS) can reduce costs by IDR 3,492,288,479 or 18,14% of the original design and shorten the construction duration by up to 53 days or 21.03%. This study recommends the systematic application of VE in similar construction projects to optimize resource utilization and improve project efficiency. The research offers both practical and theoretical contributions to the discourse on VE implementation in higher education building projects in Indonesia, including implications for national construction regulations and practices. It also evaluates the efficiency of HCS as an alternative floor slab system in high-rise educational facilities. These findings align with spatial planning principles that emphasize optimal land use and vertical space efficiency, especially in dense urban areas, and may serve as a reference for developing sustainable, construction-based zoning policies for educational areas.Keywords: Value Engineering, Cost Efficiency, Time Efficiency, Construction Project, Hollow Core Slab

Abstract

This study aims to analyze the structural behavior of Modified T-Stub steel connections under cyclic loading, with the expectation that the results can be applied to steel construction in Indonesia, particularly for structures requiring high seismic performance. In this research, conventional 4ES and Double T-Connections were modified into Modified T-Stub configurations to improve their deformation capacity, strength, and energy dissipation performance. Experimental cyclic loading tests were conducted to evaluate the structural response of the modified connections, focusing on parameters such as strength, stiffness degradation, and drift capacity. Two test specimens were used, namely WF 450×200×9×14 and WF 500×200×10×16, which represent commonly used steel profiles in Indonesian construction practice. Numerical simulations were also performed to support and validate the experimental results. The test results indicate that both specimens exhibited stable hysteretic behavior and satisfactory performance under repeated cyclic loading. The numerical analysis showed that the connections were able to achieve drift ratios of up to 5% radian, while the experimental tests demonstrated drift capacities of approximately 4% radian without significant strength degradation or premature failure. These findings demonstrate that the Modified T-Stub connections meet the performance requirements for certified Special Moment Connections (SMC). This study provides valuable insights into the development of high-performance steel connection systems and contributes to enhancing the safety, efficiency, and structural quality of steel buildings in seismic regions of Indonesia.

Abstract

ABSTRACTThe provision of vertical housing in developing cities such as Tegal faces challenges not only in construction but also in sustaining building functionality and maintenance over time. The feasibility of public rental housing (Rusunawa) constitutes a critical component of urban housing asset management to ensure safety, comfort, and service sustainability for low-income residents. This study aims to assess the feasibility level of Block B of Kraton Rusunawa within a framework that integrates technical evaluation and occupants’ perceptions. A descriptive quantitative approach was employed through checklist-based observations in accordance with the Regulation of the Ministry of Public Works and Housing (Permen PUPR No. 22/2018), combined with user assessments. The evaluation covered three main aspects: structure (45%), architecture (35%), and utilities (20%), using a 1–4 rating scale. The results indicate that all floors fall into the conditionally feasible category, with scores ranging from 1.61 to 2.12. A disparity in building conditions across floors was identified, with the fourth and fifth floors exhibiting higher levels of degradation compared to the lower floors, thereby requiring priority maintenance. These findings highlight the importance of preventive maintenance strategies and periodic rehabilitation scheduling as part of Rusunawa asset management. From a policy perspective, the study provides an evaluative basis for local governments in planning maintenance programs and allocating housing budgets within the framework to ensure the long-term sustainability of vertical housing.Keywords: Building Feasibility, Vertical Housing, Public Housing Maintenance, Urban Asset Management, Technical EvaluationABSTRAKPenyediaan hunian vertikal di kota sedang berkembang seperti Kota Tegal menghadapi tantangan tidak hanya pada pembangunan, tetapi juga pada keberlanjutan fungsi dan pemeliharaan bangunan.
