Abstract

Reinforced concrete works in bridge structures have a high level of complexity, particularly in abutment construction with significant height and unstable soil conditions. One of the most influential activities affecting construction duration is formwork work. In the Patimban Access Toll Road Construction Project Package 1, specifically at Abutment Bridge 9, soft soil conditions and limited working space became major constraints in applying conventional formwork methods that rely on ground-supported scaffolding. This study aims to analyze and compare the duration of formwork execution between the conventional method and the flying formwork method in abutment construction. The research employed a descriptive comparative approach, with the main parameter being the duration of formwork activities. Data were obtained through field observations, project documentation studies, and recording of execution time for each stage of work. The analysis results show that the conventional formwork method requires an execution time of approximately ±40 days, while the flying formwork method requires approximately ±16 days. There is a duration difference of ±24 days, indicating that the flying formwork method is more time-efficient. This efficiency is mainly influenced by the elimination of ground improvement work and multi-level scaffolding installation, which are characteristic of the conventional method. Based on the results of this study, the flying formwork method is considered more effective for abutment construction with significant structural height and unstable soil conditions.

Abstract

The utilization of fly ash and bottom ash (FABA) as a partial replacement for cement is an alternative approach to reduce coal combustion waste and the use of conventional cement in paving block production. This study aimed to evaluate the effect of FABA substitution at 0%, 5%, 10%, and 15% of cement mass on the compressive strength of paving blocks at 28 days and to identify the most effective FABA composition. An experimental method was applied using Holland-type paving blocks measuring 20 × 10 × 8 cm. FABA from PT Pusri was used with three internal FA:BA proportions at each substitution level, namely 100:0, 75:25, and 50:50. Fine aggregate was Tanjung Raja sand, while Baturaja cement and clean water were used as the binder and mixing water. Material characterization included sieve analysis, specific gravity, unit weight, and mud content. Compressive strength was determined using a compression testing machine after 28 days of curing. The results show that the control mixture had an average compressive strength of 13.00 MPa. The highest value among FABA mixtures was 13.16 MPa at 5% FABA with an FA:BA ratio of 50:50. At 10% and 15% FABA, the highest values were 12.83 MPa and 12.33 MPa, respectively. Overall, increasing FABA content above 5% tended to reduce compressive strength. The paving blocks were classified as quality D according to SNI 03-0691-1996.

Abstract

The construction of the New Ciparay Market is a public infrastructure project requiring special attention to environmental sustainability. As a hub of community economic activity with high foot traffic, the market has a significant environmental impact; consequently, the use of "green materials" in structural works has become a priority to reduce the carbon footprint and create a healthy environment for vendors and visitors. This study aims to evaluate the compliance of the structural materials used in the project—specifically K-350 Ready-Mix Concrete from PT Pionir Beton Indonesia and steel from PT Gunung Garuda and PT Lautan Steel Indonesia—with green material standards. The research employs a descriptive-evaluative qualitative approach, utilizing a comparative analysis against criteria set by the Green Building Council Indonesia (GBCI) and international standards. Evaluation parameters cover nine criteria: CFC content, durability, recycled material content, renewable sources, environmental certification, local material sourcing, Environmental Product Declarations (EPD), carbon footprint, and hazardous substance content. The results indicate varying levels of compliance: Pionir Concrete at 67% (very good), Gunung Garuda Steel at 67% (very good), and Lautan Steel at 56% (good). The primary structural materials still exhibit significant shortcomings regarding EPD documentation, carbon footprint transparency, and verification of recycled material content. Recommendations include incorporating green material requirements into technical specifications for government projects, mandating the provision of EPDs and ISO 14001 certification from suppliers, and implementing a structured green material verification system for public infrastructure projects.

Abstract

Sudirman Park is one of the active public green open spaces in Semarang City that supports the social functions of urban communities, such as social interaction, recreation, and sports. However, several aspects supporting the social functions of this park are still not optimal, including damaged pedestrian paths, limited seating, minimal shaded areas, damaged vegetation due to high intensity of use, and inadequate lighting at night, which causes discomfort and hinders social activities. This study aims to formulate development strategy of public green open space city prk based on social function in Sudirman Park, Semarang. The method used is descriptive qualitative with SWOT analysis (Strengths, Weaknesses, Opportunities, Threats), then compiles the IFAS and EFAS matrices as the basis for formulating the strategy. The results show that Sudirman Park has strengths such as free Wi-Fi, the R.M. Bambang Soeprapto Monument, a strategic location, diverse vegetation, as well as park benches and children's play areas, but also has weaknesses such as the lack of parking and sports facilities, minimal security, uneven shade, and low utilization by local residents. External opportunities include government policy support, while threats include illegal parking and nighttime security risks. The SWOT analysis places Sudirman Park in Quadrant I (Strength-Opportunity), so development strategies prioritize optimizing the park's potential through organizing social, cultural, and educational activities, improving facilities and accessibility, organizing parking and informal activities, and strengthening collaboration between the government, community, and the public to optimize Sudirman Park's social function.

Abstract

Steel beam-to-reinforced concrete column connections utilizing embedded plates are critical structural elements in industrial buildings, serving as the medium for force transfer between steel and concrete components. The performance of these connections is significantly influenced by the local behavior of the concrete and the anchorage system, particularly regarding stress distribution and the potential for concrete cracking around the connection. This study aims to analyze the performance of embedded plates in reinforced concrete columns—specifically focusing on stress distribution and concrete cracking patterns around the beam-column connection—using a nonlinear numerical analysis approach. The analysis was conducted using the Component-Based Finite Element Method (CBFEM) via IDEA StatiCa 25 software (Concrete → Detail module) under ultimate limit state (Strength) conditions. Design loads for the factory building were applied locally to the end of the steel beam as axial and shear forces, implementing both live and dead loads. The analysis results show that the principal tensile stress in the concrete (σ₁) is locally concentrated around the embedded ends of the anchors, serving as an early indicator of potential concrete cracking, while the principal compressive stress (σ₃) forms a bearing zone around the embedded plate with values remaining below the concrete's compressive capacity. The analysis shown a maximum tensile stress of -1 MPa and a minimum compressive stress of -8.7 MPa; however, these stress levels remain within the allowable stress criteria for concrete as stated by SNI 2847:2019. These tensile and compressive stresses result in local deformation around the embedded plate. The study shows that the CBFEM approach realistically represents the local behavior of the connection and serves as a viable evaluation tool for the design of steel beam-to-concrete column connections in industrial buildings.
