Abstract

Hospitals are essential in providing health services and must withstand the forces that may occur, even due to an earthquake. RSUD Soedarso is a hospital in Pontianak City that has been around for a long time. However, because it is already quite old, various problems must be addressed. The step taken by the government is to build a new building, namely the Medical Centre and Inpatient Building.The purpose of writing this final project is to evaluate the performance of the earthquake-resistant structure of the Soedarso Hospital Medical Centre building using the pushover analysis method. This method analyses the inelastic behaviour of the system due to the earthquake, where the result is a curve of the relationship between the shear force and the displacement of the roof that occurs. The guidelines for pushover rules used are based on the provisions of ATC-40 and FEMA 356. Further research was carried out on the dilation between the Medical Centre Building and the IRNA Building.The results are that both buildings are still in elastic condition when the performance point is reached. Based on ATC-40 and FEMA 356, the building is classified as in the Immediate Occupancy (IO) performance level, regarding drift ratio and from plastic hinges that occur in column and beam elements. Then the dilatation that arises due to pushover is smaller than the design dilation of 150 mm. Both buildings are protected from potential collisions, which is a relief.

Abstract

The successful implementation of a job begins with the determination of a reliable estimation value. One of the models used in determining the estimated value of a job, using data from the cost budget plan (RAB) on work that has been carried out, is the Cost Significant Model.  In this study, the data used were five suspension bridge construction jobs starting from 2018 to 2022. the data obtained from the RAB is processed into independent variables and dependent variables, which are then tested using multiple linear regression methods using the SPSS application. Based on the results of the analysis, the influential variables are X2, namely Bridge Oprit Work; X4, namely Upper Building Work (Transportation and Installation of Truss Bridges); and X5, namely Lower Building Work (Angkur Block Work, Pyilon Foundations, Wind Ties) with a total weight of 85.30%.  By using the equation Y = -21,640,343,680,000 + (1,856,843,372 x X2) + (453,953,095 x X4) + (41,965,201,370 x X5), the maximum value of 62.21% and minimum value of -98.05% are obtained, so it falls into the Class 5 category. Class 5 has an accuracy value ranging from +30% to +100%, so it is estimated that it is feasible to use it to carry out the initial concept screening estimation.

Abstract

The rapid development of physical and infrastructure projects in Indonesia necessitates efficient building materials. Mortar, a standard construction material comprising fine aggregate, water, and cement, has strength, environmental resistance, and flexibility limitations. This study investigates using epoxy resin as a substitute for cement in mortar production. Epoxy resin, a liquid material that hardens into a strong binder, offers potential benefits such as accelerated setting time and increased strength. The research uses river sand as the fine aggregate and varies the epoxy resin content from 5%, 10%, 15%, 20%, and 25% of the material volume. Tests will measure compressive strength, split tensile strength, and modulus of elasticity across different epoxy resin compositions. Results from Tanjung Pura University's Materials and Construction Laboratory in Pontianak indicate that adding epoxy resin significantly improves compressive strength (up to 35.92 MPa at 25% resin) and tensile strength (up to 3.82 MPa at 25% resin). However, adding epoxy resin leads to a decreased modulus of elasticity, indicating increased deformability. This research sheds light on epoxy resin's impact on mortar strength and informs potential applications in concrete repair and construction.
