Abstract

The condition of the building in the building of PT. Suri Tani Pemuka Cirebon experienced a few problems in building material components such as materials made of steel which have begun to show the presence of corrosion in steel. This is caused, among others, from the negligence of poorly controlled boiler engine settings. thus raising issues regarding eligibility in building structures. This study aims to determine the residual strength, deflection value, and interstory drift in building structure components and to determine the level of structure safety in the existing building conditions. The flowchart is carried out starting with a field assessment then a literature study continues with measurement and analysis assessment, followed by analysis, conclusions and finishing. From visual observation and structure calculation, the structure of plant 1, plant 2 and warehouse, is still functioning well and is suitable for use as long as there is no corrosion and technical disturbance that occurs.

Abstract

Soil compaction is an important process in reclamation work because it has a direct effect on the carrying capacity and stability of the structure built on it. This study was conducted in one of the specific work zones of Area C1a in the Patimban Port reclamation project, where sand material from various quarry sources is used, each having different physical characteristics that can affect the success of compaction. This study aims to analyze and compare the results of material compaction from four different quarries using the field density test (sand cone) and laboratory carrying capacity test (CBR) methods. The research methodology includes the analysis of physical characteristics such as particle size distribution and sludge content, as well as compaction quality testing after applying the same number of vibratory roller passes to each material. The results showed that the material from Quarry A achieved the highest average field density (104.71%), indicating the highest compaction effectiveness among the materials tested. In terms of carrying capacity, the material from Quarry B proved to be the most superior, with the highest CBR value both in dry conditions (103.00%), after submersion (58.00%). In contrast, the Quarry C material showed the highest sensitivity to water, as its CBR value decreased from 75.00% to 27.00% when submerged, which correlated with the highest silt content (9.21%). These findings demonstrate that the physical characteristics of materials, such as silt content and grain size distribution, are the main determining factors affecting the final yield of soil density and carrying capacity.

Abstract

This study examines the construction management of the Royal Techno Park Mundu Cirebon project using Microsoft Project software. The background of this research arises from the increasing complexity of construction projects in Indonesia, which demand effective project management to control time, cost, and resources. The research employs a mixed-methods approach, combining quantitative and qualitative methods through literature reviews, field surveys, and secondary data from relevant agencies. Analysis is carried out using scheduling techniques such as Bar chart, S-Curve, and Critical Path Method (CPM) to optimize resource allocation and accurately monitor project progress. The findings indicate that utilizing Microsoft Project enhances planning accuracy and project control, thereby minimizing the risk of delays and cost overruns. Moreover, a comprehensive needs analysis regarding materials, labour, equipment, and costs proves crucial for successful project execution. This study also emphasizes the importance of integrating information technology into planning and implementation processes, which facilitates real-time monitoring and responsive decision-making. Thus, structured construction management and periodic evaluations are key to achieving optimal and efficient construction outcomes. These findings are expected to serve as a reference for practitioners and academics in developing construction management strategies in the digital era.

Abstract

Structural and spatial planning for category D hospitals to be considered feasible both structurally and in terms of quality requirements, must be guided by SNI 1726:2019 and Regulation of the Minister of Health of the Republic of Indonesia No.24 of 2014. Hospital D is a hospital with basic health services and is located in rural or remote areas and is the first referral from the community health center. In addition to planning, a building structure analysis is also carried out and as an illustration of whether the building is safe after analysis. Details and dimensions of the plates, beams, columns, and foundations are also sought. There are 2 methods used for this planning, namely quantitative and qualitative methods, with secondary data. Planning data is determined starting from the overall function of the building, the number and function of each floor, the type of structure, the height of the building, the height of each floor, and the roof covering. The planning made consists of structural components in the building including plates, beams, columns, and foundations. The material used in the building is concrete with a quality of 20.05 MPa, while the quality of the reinforcing steel used is 420 MPa. Modeling and analysis of the hospital building structure was carried out using ETABS 16 software, while for structural visualization using AutoCAD 2014 software. The loads entered were dead load, live load, wind load, and earthquake load.
