Abstract

Several testing methods can be carried out in testing the bearing capacity of the soil, such as soil test testing, hand penetrometer, dynamic cone penetrometer, plate bearing test, and others. In addition to direct testing in the field, testing can also be carried out in the laboratory. The purpose of this study is to determine how much the correlation results of the 4 (four) test methods are to provide efficient results in data collection in the field. The location of research was carried out in Sekadau Regency, Sekadau Hilir District. The Sports Stadium Complex Development Plan has carried out as many as 20 (twenty) points for each test. Each test was carried out closely and reviewed at a depth of one meter, with soil characteristics at The test location being sandy soil with fine grain. The correlation test was carried out with 4 (four) test methods using the regression line method. This study shows a solid correlation between CBR Dynamic Cone and Hand Penetrometer (r = 0.893). The strong correlation between Hand Penetrometer and the qc Soil test (r = 0.669). Good modulus subgrade (Plate Bearing Test) correlation with CBR Dynamic Cone Penetrometer (r = 0.417). Very weak correlation of Soil test qc with subgrade modulus (Plate Bearing Test (r = 0.226).

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

Soil stabilization is mixing soil with specific materials to improve the soil's technical attributes to meet specific technical requirements, such as increasing its stability. One stabilization method is chemical stabilization, which utilizes mixing heaped soil using lime and Spent Bleaching Earth (SBE). This research is focused on the effect of mixing lime with SBE for soil stabilization with maintenance time between 0, 7, and 14 days. The amount of lime used in the research is 4% from the soil dry weight with variations of the SBE mixture of 5%, 10%, 15%, and 20%. The conclusion obtained in this study was that adding SBE could increase the maximum dry density up to a percentage of 10%. Using SBE of more than 10% reduces the maximum dry density value but increases the optimum moisture content. From the mechanical attributes testing carried out, it can be seen that a percentage of 10% can increase the results of mechanical testing, while an increment above 10% will reduce the mechanical results. Based on the CBR and UCS test results, we found that lime and SBE mixture can pass the attributes limit for a grade S aggregate foundation layer and full-fill the requirement as a road body foundation layer. So, it can be concluded that lime and SBE mixture can be used as a road body foundation layer but has not reached the target for road foundation layers and requires maintenance for some time.

Abstract

Various studies have been carried out to improve the parameters of soil mechanical properties. Efforts to improve the mechanical properties of the soil can be carried out in multiple ways, including automated means through compaction and chemical means through the addition of cement base materials. To improve the stability and properties of the subgrade soil, the cement base material that is commonly used is Portland Composite Cement (PCC). In several studies, apart from cement base materials, waste base materials have also been used for stabilization subgrade. This includes using bleached soil residues and rice husk ash as additives to stabilize the soil. The results showed that the use of soil bleaching waste in soil cement stabilization can be used to improve the mechanical properties of the embankment soil and the composition of the soil bleaching waste mixture so that mechanically, it is proven to provide the most effective improvement so that it can be used for road foundation layers made of cement soil. As part of this research, many tests can be carried out on normal and stabilized soils. Various percentages of SBE are 5%, 10%, 15%, 20%. PCC is introduced into the soil at a rate of 8% of the dry weight of the soil.

Abstract

Illegal gold mining is extracting gold without a formal license from the government or competent authority. It presents a significant environmental and geological challenge in Bengkayang Regency, Indonesia. This practice, carried out without proper authorization or adherence to safety regulations, is recognized as a significant cause of slope instability in the area.This study analyzes slope stability from unlicensed gold mining in Kinande Village, Bengkayang Regency. It uses manual Fellenius calculations and Geo Studio/Geo Slope 2023 software to determine the Safety Factor (SF) for potential landslides, assuming circular landslide planes are unaffected by earthquakes.Laboratory tests revealed varying soil types and properties at these points, impacting shear strength and slope stability. Loamy soils exhibit high cohesion but low internal friction, making them susceptible to instability. Sandy soils lack cohesion and rely on particle friction. Shear strength parameters like cohesion (c) and internal friction angle (φ) are critical in assessing slope stability. The study employed the Fellenius method and Geo Studio 2023 software to analyze slope stability, with safety factor (SF) results indicating potential hazards. Mining in plain areas showed favorable SF values (>1.5), suggesting activity safety. Conversely, mining in mountainous and watercourse areas exhibited lower SF values (<1.5), indicating instability and safety risks. Recommendations include stratified mining practices to maintain stable slopes and ensure miner safety. This research contributes to understanding geohazards and proposes measures for enhanced safety, environmental sustainability, and regulatory governance in mining areas. Understanding and analyzing these factors are crucial for the stability and safety of geotechnical projects, ensuring balanced shear stress and shear strength for slope stability.

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.
