Building fires can significantly degrade the strength and integrity of steel structures, so post-incident evaluation is crucial to ensure building safety and feasibility. This study aims to evaluate the condition of the steel tower structure after the fire through a visual inspection method. A total of 35 structural elements were examined, including columns, beams, and bracing, to identify damage caused by heat exposure. The inspection results showed that 6 elements (17%) were in the category of Acceptable, 8 elements (23%) Needs Attention, 5 elements (14%) Not Acceptable, and 1 element (3%) Not Applicable because they had been removed. Steel columns generally remain upright without deformation, but suffer damage to the protective layer (coating). In contrast, most blocks lose their protective layers, are directly exposed to fire, show early signs of corrosion, and some suffer severe damage such as flange tears and cuts. These findings confirm the importance of systematic documentation and classification of element conditions as the basis for technical decision-making for structural improvement. Visual inspection proved effective as an initial step in the evaluation process, providing a relevant initial picture of the extent of damage and the need for intervention. This study recommends follow-up in the form of advanced structural analysis and material testing to ensure the feasibility of reusing the affected steel elements.

. Perancangan dan pemodelan struktur merupakan unsur yang esensial pada suatu bangunan agar dapat menghasilkan struktur yang kuat, stabil, dan awet.

The building to be utilized should undergo regular inspections and performance testing to determine whether it can function and operate according to its intended use. Compliance with administrative and technical regulations governing the utilization of buildings is demonstrated through the issuance of a Building Worthiness Certificate (SLF). This study aims to assess the compatibility of the building's function with the conditions during the planning phase and evaluate the structural feasibility of the building. It also seeks to implement the provisions of Government Regulation No. 16 of 2021 regarding the Implementation of Law No. 28 of 2002 on Buildings. Based on the research conducted, it can be concluded that the structural suitability of the MSC Indosat Baturaden building has changed compared to the planned building. Initially designed as a battery storage building, it is currently used as an MSC building or a facility for storing batteries and servers. Additionally, there are discrepancies in the area specified in the original Building Permit (IMB) compared to the current building. Further analysis of the building's structure and the application of current regulations regarding structural serviceability, including dynamic load analysis (earthquake), inter-story drift analysis, P-Delta analysis, and structural cross-section checks, concluded that the building is safe as it meets the requirements specified in SNI 1726:2019 and SNI 2847:2019. The highest structural cross-section capacity ratio was 0.2 < 1, and the inter-story drift value was 0.023 < 0.07. The existing concrete material meets the structural standards, with a characteristic compressive strength of 28.98 MPa. The results of the rebar scan detector test showed that the type of reinforcement used complies with the standards specified during the planning phase, referring to SNI 07–0408–1989. Overall, the structural analysis results for the MSC Indosat Baturaden building indicate that the building is safe and remains fit for use.    

A mixed-use building refers to a combination of several different functions within a single structure, such as residential, office, shopping, and recreational functions built on one site. Designing a mixed-use building requires careful planning and consideration of various factors such as functional needs, aesthetics, and energy conservation. Additionally, the design of mixed-use buildings incorporates various functions within a single area. Floor slabs and beams use plain reinforcing steel with a quality of Fy = 240 MPa (Ø8mm). The concrete cover is taken as 20 mm. From the design results, several thickness types of slabs were obtained according to the load requirements that must be accommodated above them. The following are the moments acting on the floor slabs and beams. The reinforcement calculations are performed using the capacity strength design method according to SNI 2847-2019. The capacity design concept involves controlling the formation of plastic hinges at predetermined locations. The SAP2000 program can directly calculate the feasibility of the structural dimensions and the amount of reinforcement needed from the input program results. In the SAP2000 program, the concrete code used is the American concrete code ACI-318-05/IBC 2003, which differs in some respects from the concrete code in Indonesia SNI 2847-2019. Adjustments need to be made to comply with the regulations in Indonesia. Internal forces from the SAP2000 program are selected from load combinations that generate the maximum moments at the column face. The flexural and shear reinforcement for beams can be directly read from the SAP2000 output in the form of information on the required area of reinforcement. 

This study aims to redesign the superstructure of the Sambungrejo Bridge in Sidoarjo, which has a span length of 16 meters. The Sambungrejo Bridge originally used WF 700.300.15.28 steel girders and C 300.100.10.16.8 diaphragms,that are susceptible to corrosion, especially during floods. The redesign involves replacing the steel girder with a Prestressed Concrete I Girder (PCI Girder) H-900mm, 170mm thick, produced by WIKA Beton, known for its superior corrosion resistance and construction efficiency. The research methodology includes structural analysis using Robot Structural Analysis Professional (RSAP) software, calculation of prestressing forces, and the design of the prestressing cable layout. The results of this study demonstrate that the use of PCI Girder does not reduce the structural dimensions of the bridge but also proves to be more compatible with the flood water conditions at the site. The total cost required for implementing the new bridge superstructure design is Rp. 4.372.201.

Co-working spaces have gained popularity in recent years as a flexible and cost-effective solution for freelancers, startups, and small businesses looking for a collaborative work environment. This article examines the key success factors for a co-working space business model, drawing on insights from industry experts and research studies. By identifying these critical factors, co-working space operators can optimize their business model and enhance their chances of success in a competitive market. The development of the use of co-working space is now increasingly promising. Many of the startup companies and freelancers who use co-working space as a place for daily activities to work. Co-working space also helps to differentiate work and daily activities from these workers. However, the business model of co-working space is relatively vulnerable. This study aims to evaluate the factors that can increase the success of the co-working space business model, considering the importance of co-working space as the development of creativity. This study involved 116 users from two businesses that achieved success in managing the co-working space. Data was collected using a questionnaire survey and structurally analyzed using SmartPLS. The results of the study identified that shared workspace management and supporting co-working space operations played an important role in determining the success of this business model. Membership management has no significant effect. Therefore, the management of co-working space can be focused on these two elements
