Abstract

The Gandus Camping Ground Access Road Construction Project is required to be completed on time so that consumer confidence is maintained. To achieve this, control is needed which must be known in advance through ongoing project performance. One way to determine project performance is the Earned Value method which integrates aspects of cost, time and work performance. Therefore, this Earned Value analysis is applied to the Gandus Campground Access Road Construction Project. Project performance is analyzed based on cost performance index (Cost Performance Index) and time (Schedule Performance Index). Calculations are based on planned value, earned value and actual costs. Performance control is reviewed for 8 weeks, namely week 12 to week 19. The results of the analysis in weeks 12 to 19 show that the costs incurred were greater than planned and the implementation time was longer than planned as indicated by the average value of CPI = 0.976 (CPI <1) and the average value of SPI = 0.999 (<1). The results of the estimated final project cost are IDR 3,740,377,358.49 with an implementation time of 24 weeks, which means the project will be in accordance with plan.

Abstract

Traffic performance refers to the evaluation of the service quality of a road segment relative to the traffic flow through it. Road traffic performance assessment is measured by the degree of saturation and travel speed. Road capacity (C) is the ability of a road section to accommodate traffic flow in a certain time unit. Road capacity is influenced by the type of side obstacles and the frequency of occurrence. This research was conducted on Jalan Jenderal Ahmad Yani Campus A, Muhammadiyah University of Palembang to calculate road capacity (C) and traffic performance on Jalan Jenderal Ahmad Yani.  Data analysis was carried out using the 2023 Indonesian Road Capacity Guide where road capacity and degree of saturation are road traffic performance parameters so that the value of the level of service is known. Based on the results of research and analysis that has been carried out located on Jalan Jenderal Ahmad Yani, Palembang, the road capacity (C) is 2,924 PCU/hour and the free flow speed (VB) value is 49.59 Km/hour, while the road traffic performance and level of service on the Jalan Simpang 4 Jakabaring-Jalan Jenderal Ahmad Yani section is 0.81 and is classified as category D (Flow is close to stable, speed can still be controlled, traffic volume is approaching capacity), while from the direction of Jalan Jenderal Ahmad Yani -Intersection 4 Jakabaring obtained a service level of 0.94 and was classified as category E (Unstable flow and sometimes stopping, traffic volume approaching capacity, low speed and changing).

Abstract

This research aims to analyze the comparative structural behavior of reinforced concrete buildings using variations in square and circular column geometries. The research object is a 6-story educational building with dimensions of 35.1 x 23.4 meters and a total height of 24.2 meters. The analysis was conducted using ETABS v18 software by varying square column dimensions (55/55 cm, 50/50 cm, 45/45 cm) and circular columns (diameters of 62 cm, 56 cm, 50 cm). The parameters examined include internal forces, section capacity, and structural drift. Research results indicate that the difference in internal forces between the two column types is relatively small (1-2%). Circular columns demonstrate higher capacity in resisting axial loads (5098.01-7609.09 kN) and moments (295-520 kNm) compared to square columns. Although circular columns show slightly larger drift values, both column types meet the established drift limit requirements with safe margins. This research concludes that both column geometries demonstrate good structural performance and can be used interchangeably in structural design, with circular columns having advantages in section capacity but accompanied by slightly larger drift values.

Abstract

The latest advances in science and technology have positioned nanomaterials at the vanguard of contemporary research. Nano silica (SiO2) is an illustrative example of a nanomaterial extensively utilized in concrete manufacturing due to its properties as a pozzolan. The objective of this study is to elucidate the characteristics of nano silica and its effect on the performance of polymer concrete through experimental methods. X-ray diffraction (XRD) tests indicate that nano silica exhibits a high amorphous phase. Consequently, nano silica enhances the C-S-H gel formation reaction, producing more robust and denser specimens. The maximum compressive strength reached 45.23 MPa when adding 0.4% nano-silica with a specific gravity of 1573.33 kg/m3. For comparison, concrete without nano silica had a maximum compressive strength of 40.05 MPa with a particular gravity of 1610.67 kg/m3. Observation using a scanning electron microscope (SEM) showed that the nano-silica mixture exhibited excellent particle distribution as an activating agent that could enhance the strength of the specimens. Nevertheless, the observed reduction in compressive strength might be affected by several factors, including particle clusters and the presence of compounds carried by the fine aggregates that influence the mechanical properties of polymer concrete. Integrating nano-silica is pivotal in enhancing the compressive strength and reducing the specific gravity of polymer concrete specimens. The increased strength and decreased specific gravity render nano silica a promising additive for polymer concrete applications.

Abstract

This research focuses on the development of polymer mortar using epoxy as a binder, fly ash as an additive, and nanosilica as nano-filler. The study investigates the effect of nanosilica variations on the mechanical properties of polymer mortar, specifically density and compressive strength. The research used nanosilica content variations of 0%, 1%, 2%, 3%, 4%, and 5% of the mold volume. Material composition consists of 45% sand, 17.5% epoxy, 17.5% hardener, 20% fly ash, and varying nanosilica percentages. Test results show that increasing nanosilica content decreases the density of polymer mortar from approximately 1880 kg/m³ (0% nanosilica) to 1730 kg/m³ (5% nanosilica). Meanwhile, compressive strength increases up to 2% nanosilica content with an optimum value of 60.31 MPa (an 87.3% increase compared to mortar without nanosilica), then decreases with further addition of nanosilica. The findings suggest that 2% nanosilica represents the optimum content for enhancing the mechanical performance of epoxy-based polymer mortar.

Abstract

This study examines the effect of nano-silica addition and temperature variation on the durability of polymer mortar exposed to seawater. We investigated three specimen variations: polymer mortar without nanosilica (MP), polymer mortar with 0.4% nanosilica added (MP N 0.4%), and nanosilica polymer mortar with 85◦C heating (MP N 0.4% T 85◦C). Testing methods included cyclic and static immersion for 90 days in Tanjung Pandan, Bangka Belitung, followed by characterization through specific gravity, compressive strength, SEM (Scanning Electron Microscopy), FTIR (Fourier Transform Infrared Spectroscopy), and XRD (X-ray diffraction) analysis. Results showed that 0.4% nano-silica addition combined with 85◦C heating treatment significantly increased compressive strength to 51.78 MPa in cyclic immersion, compared to 38.17 MPa for standard polymer mortar. SEM analysis revealed a more compact microstructure with reduced porosity in nano-silica specimens, while FTIR confirmed the formation of new chemical bonds between the epoxy matrix and silica particles. XRD testing identified the presence of SiO2 crystalline phase and nano-silica distribution in amorphous form throughout the composite matrix. The optimized polymer mortar demonstrated superior durability in seawater environments, maintaining specific gravity stability and resistance to degradation after prolonged immersion, outperforming conventional cementitious materials in marine applications.
