Abstract

This study presents a comparative seismic performance analysis of a 10-story commercial building in North Jakarta, an area characterized by high seismicity and challenging geotechnical conditions. Two identical structural models were analyzed using ETABS v2022: one using a lightweight precast concrete panel system (JOE Green X3) and the other using a conventional Autoclaved Aerated Concrete (AAC) lightweight brick system. The aim is to compare the seismic structural performance of the analysis, based on the response spectrum method in accordance with SNI 1726:2019, revealed that the precast concrete panel system, was 14.4% lighter than the AAC lightweight bricks system when accounting for its full installed weight, including plaster and bracing columns. It resulted in a shorter fundamental period (0.412 s) compared to 0.453 s of the AAC lightweight brick system. However, the seismic base shear forces are nearly identical due to compensating effects in the site-specific response spectrum. Although both systems meet the deflection limits mandated by regulations, their performance is direction-dependent. This study concludes that the substantial reduction in total mass of the precast panel system provides a shorter vibration period but comparable seismic performance to the AAC lightweight brick system.

Abstract

In the digital era, innovative learning methods are key to increasing student engagement and understanding in engineering and construction. One of the increasingly emerging approaches is game-based learning (GBL), where games are used as interactive educational tools. This study explores the effectiveness of Minecraft: Education Edition in improving academic performance and engagement of students in the Construction Engineering and Management (CEM) Study Program at a university in Indonesia. This study used a mixed method, namely learning observation and questionnaire survey of students attending Minecraft-based lecture sessions. The findings of this study are presented in three main topics, namely the implementation of Minecraft: Education Edition as a learning medium, the Effectiveness of Minecraft as a Learning Medium for Construction Management, and implementation barriers. The results of this study are expected to provide insight into best practices in engineering education, especially in the application of interactive technology to improve learning effectiveness. This study also provides recommendations for higher education institutions to adopt game-based learning as part of innovative strategies in engineering learning. With increased student engagement and understanding through game-based simulations, Minecraft has the potential to be a revolutionary educational tool in the construction discipline.

Abstract

Many prior studies focused on construction workers' perceptions of safety compliance, but little or no research has been undertaken to investigate the relationship between construction project sacrifice and safety compliance. Construction project sacrifice – known as ‘tumbal proyek’ in the Indonesian Language is a socio-cultural phenomenon that still exists in Indonesian society. This research examines the perceptions of construction workers regarding project sacrifice and their relationship to workers’ compliance with construction safety management. A mixed-method approach was employed, which consisted of an integrative literature review and questionnaire surveys. In total, there were 102 valid survey responses, which were analysed using Structural Equation Modelling-Generalised Structured Component Analysis (SEM-GSCA). The analysis demonstrates a positive relationship between workers’ perceptions of project sacrifice and safety compliance. This study adds by offering empirical data on the phenomenon of project sacrifice and how workers' perceptions of it can influence the construction safety compliance in Indonesia. Although this is a context-specific study, the findings can serve as a reference for future research to enhance the safety climate in construction projects.

Abstract

Concrete damage is often linked to reduced structural strength due to rapid setting, which complicates compaction and placement. Chemical retarders are commonly used to address this issue but are costly and environmentally unfriendly. Molasses, a by-product of the sugar industry containing sucrose, glucose, and fructose, offers a potentially eco-friendly and economical alternative. This study compares the effects of molasses and a chemical retarder (Plastiment VZ) at dosages of 0.2–0.4% on concrete compressive strength and initial setting time. Results show that 0.35% molasses increased compressive strength to 25.48 MPa compared to 19.53 MPa in normal concrete, though strength declined at 0.4%. Plastiment VZ showed more consistent gains, reaching 25.90 MPa at 0.4%. For setting time, molasses delayed hydration to 435 minutes (0.4%), while Plastiment VZ extended it further to 690 minutes (0.4%). Thus, molasses can serve as an alternative retarder, though Plastiment VZ provides more stable effects.

Abstract

Infrastructure growth in Sorong requires innovative construction materials that are efficient, durable, and environmentally friendly. Cellular Lightweight Concrete (CLC) bricks are proposed as an alternative to conventional red bricks. This study investigates the compressive strength and density of CLC bricks made with Sorong sand, using Cikarang sand as a comparison. Laboratory trials were conducted to develop a mix design with a target density of 800 kg/m³. The results show that CLC bricks using Sorong sand reached densities of 821.73–867.16 kg/m³ and compressive strengths of 0.81–1.11 MPa at curing ages of 3, 7, and 14 days. These values were slightly lower than those of Cikarang-sand bricks, which achieved densities of 831.11–879.01 kg/m³ and strengths of 0.81–1.26 MPa. The reduced strength of Sorong-sand bricks is related to their lower density. Nonetheless, testing confirmed that Sorong sand meets fine aggregate specifications, making it suitable for CLC brick production and supporting local infrastructure development.
