Abstract

The implementation of infrastructure activities, whether in the form of building construction or road construction, always requires and involves a large number of workers, construction activity organizers, especially service providers or contractors who have a workforce of various levels directly related to the field, especially workers in the area are very vulnerable to occupational safety and Health, especially in road paving work in cities, where asphalted roads are roads with high and dense vehicle traffic. For this reason, the authors conducted an Analysis of the Effect of Occupational Safety and Health on Road Paving Workers in Pontianak City.All data must first be tested for data validity and reliability using the statistical program SPSS Version 26 to find out the analysis results. The data processing method uses quantitative methods. Then the Author will carry out a regression analysis so that it can be seen to what extent the influence of hazard and risk identification safety at work on occupational risk control, occupational safety, and health programs on road paving work in the city of Pontianak, as well as to find out the dominant factors that determine the value of occupational risk control.

Abstract

The height of the bridge arch significantly impacts the strength and structural efficiency. Research on the height of the Tayan Bridge arch was conducted to determine the values and behaviour of member forces, structural weight, and deflection and to design the optimal arch height geometry. This research involved five variations of the arch height. The bridge structure was modelled using AutoCAD software. Relevant bridge loading data based on the SNI 1725-2016 standard was inputted into AutoCAD for structural design, and then the structure was modelled and analysed using SAP2000. The analysis results provided information on the bridge weight, deflection, and member forces. The analysis results were then compared with the bridge arch height, and this comparison was presented in the form of graphs. From the analysis results, it can be concluded that the bridge arch height has a positive linear relationship with the bridge weight. Tensile and compressive forces exhibit opposite behaviour. Increasing the arch height with constant value results in weight, deflection, and member force variations. Constantly expanding the arch height also does not lead to an increase in the stiffness of the bridge. Structurally, the optimal arch height is 42.134 meters.

Abstract

The mild to moderate earthquake zone includes the West Kalimantan region, especially Pontianak City. Along with the development of science, regulations governing building construction are continuously updated. SNI 1726-2019 results in that every building in the current mild earthquake zone must consider the earthquake force parameters so as not to cause a significant loss impact. Therefore, the design of an eight-story flats structure located in Pontianak will be carried out to obtain the dimensions of structural components resistant to earthquake loads based on SNI 1726-2019. This building design is a reinforced concrete structure with a moment-bearing frame system, and the structural analysis is modeled with a structural analysis program. The structural dimensions used are 100 mm thick floor plates, 350/700 mm and 400/800 mm for the primary beams, 250/500 mm for the secondary beam, and 800x800 mm columns. This building is included in KDS C, so the earthquake force-bearing structural system used is the Medium Moment Bearing Frame System (SRPMM). This structure has a type 2 horizontal deviation or inner corner deviation and a type 2 vertical deviation or weight (mass) deviation. Based on the structural analysis results, it is then adjusted to the structural parameters by the Indonesian National Standard (SNI). The results of the structural analysis are then continued with the calculation of reinforced concrete structures in accordance with the Indonesian National Standard (SNI) to ensure that the results meet the required safety criteria.

Abstract

A solid foundation is a concrete mix using steel reinforcement, but the reinforcement has the disadvantage of being corrosive when used in coastal areas. Therefore, this research uses strapping bands as a substitute for steel reinforcement. This research is focused on the manufacture of mortar plates for lightweight construction, especially in foundation parts such as footing foundations.  This research used 5 (five) variations of slab mixture including, variation A1 which is mortar slab without additional strapping band, variation B1 which is mortar slab with additional 3 pieces of strapping band as thick as 1 layer on each top and bottom layer, so on up to variation B4 as thick as 4 layers. The results of the mortar plate bending test obtained the value of the bending moment of variations A1, B1, B2, B3, and B4 are 0.148 kN.m; 0.183 kN.m; 0.222 kN.m; 0.278 kN.m; 0.325 kN.m. Then the maximum bending moment value is averaged in the variation that uses a 4-layer thick strapping band. From this research it can be concluded that to get a high bending moment value, the more strapping bands are used.

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.

Abstract

Reinforced concrete, a popular construction choice, is often selected due to the limited availability of materials like wood and increased familiarity with concrete. However, coastal structures using steel bars in reinforced concrete usually face corrosion issues. Corrosion can be mitigated by increasing concrete compressive strength and enlarging the concrete cover to protect the steel from saltwater. These measures are challenging for small structures due to the small dimensions of columns, beams, and plates, making thick concrete covers difficult. Additionally, small structures are often built manually or semi-manually, complicating the achievement of higher compressive strength and watertightness. However, there is hope. Researchers have developed reinforced concrete with non-metal reinforcement, such as fiber mesh and nylon rope, and combined regular and lightweight concrete to reduce dead loads, creating a sandwich concrete slab. Test results show that the slab has sufficient strength for light construction, with a strong bond between mortar and foam concrete. Although fiber mesh and nylon rope do not yet increase the slab's flexural strength, nylon rope prevents brittle failure. This promising research paves the way for further studies and potential improvements in the future.

Abstract

Buildings should be designed for strength and longevity, considering various loads like live, dead, and wind. In Kalimantan Barat, particularly Pontianak City, mild to moderate earthquakes are common, making it crucial to follow SNI 1726-2019 regulations for earthquake-resistant design. This includes using a Moment Resisting Frame system that allows the structure to absorb lateral forces and prevent sudden collapse. The chosen system reflects the building's function and soil data, ensuring it meets safety and practicality standards. For the Ayani Square Building, intermediate Moment Resisting Frames with seismic design category C were employed. The structure must adhere to SNI 1726-2019 for safety, with reinforcement designed per SNI 2847-2019 to enhance robustness. Spun piles are used in the foundation to provide stability and load-bearing capacity, effectively reducing seismic impact in moderate hazard zones.
