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

Project performance is greatly influenced by labor productivity. The productivity of each worker is different and is influenced by several factors such as work experience, age, education level, wages, site conditions, weather, coordination and planning, and leadership skills. This study examines the value and level of labor productivity, the variables that influence productivity, and the efforts to improve labor productivity. Observations in this study were conducted using the construction sampling method to observe the work scope, construction time, number of workers, adequate time, contribution time, ineffective time of lightweight steel-roof frame construction work, and direct on-site observation. Next, the level of labor productivity must be analyzed using the Labor Utilization Rate (LUR) approach. The analysis shows that the average productivity values for horse labor were 2,581 m ²/OH for ironworkers and 5,197 m ²/OH for manual workers. The productivity value for ironworkers in lath construction is 5,256 m ²/OH. From the analysis of the average level of labor productivity (results are more than 50% of her), it can be concluded that the level of labor productivity in the construction project of the catholic church of St. Maria Bunda Pengharapan Bunut Sanggau is satisfactory. The most significant variables affecting labor productivity are control variables. As a result of interviews with stakeholders, it was found that ways to increase labor productivity include effectively using time, creating a working system that is easy to work in, ensuring that workers have specialized knowledge, and ensuring thorough on-site supervision. Improvements are needed to create a good working environment.

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

A construction project is a series of interrelated activities to achieve specific goals (buildings/construction) within a particular time, cost, and quality constraints. One crucial resource in this context is construction equipment or heavy machinery. West Kalimantan is renowned for its abundant palm oil production, including in Sekadau Regency. Due to the lack of palm oil processing factories, PT. Agro Plankan Lestari constructed a palm oil factory. The research findings indicate that the average performance efficiency of the excavator was 64% (considered good) for both excavators. However, the average Overall Equipment Effectiveness values for both operators were below the tolerance level set by the Japan Institute of Plant Maintenance (JIPM), which is 40%. The average overall equipment effectiveness values of excavator A obtained an average value of 39.82%, and excavator B obtained 41.69%.

Abstract

The SIM Irrigation Area has an area of 10,860 Ha and a primary canal length of 27,022 m, which passes through the Regencies of Madiun, Magetan, Ngawi, and Madiun City. One of the secondary canals in the D.I SIM is the Ngabean Secondary Canal, located in Ngawi Regency. This canal receives the main water supply from Jati Dam, 25% of the primary dam discharge and water withdrawal from the Ngabean Dam intake of 0.45 m3/ha. However, this value only meets the water needs of some of the irrigation areas. Due to the limited supply from the Jati Bendung, the government is working on rehabilitation work at the Jati Bendung. Apart from that, the Ngabean Secondary Canal also experienced a reduction in the irrigation area from 1840 ha to 1818 ha, to be precise in the NG3 Ki tertiary plot, which had an initial area of 120 ha to 98 ha. Therefore, an evaluation of the Ngabean Secondary Canal is needed to determine the value of water demand, water availability before and after rehabilitation and land reduction, and increasing agricultural profits.From the results of the analysis that has been carried out, it was concluded that the highest dependent flow at Ngabean Dam was 5.00 m3/s, and the lowest was 0.01 m3/s. Meanwhile, in conditions before rehabilitation, the highest dependent flow of Jati Dam was 1.01 m3/s, and the lowest was 0.00 m3/s with water withdrawal at the intake of 25%, able to fulfill the planting pattern of paddy (15%)-crops (75%)-crops (50%) generated a production profit of IDR 8.794.123.880,00. Meanwhile, after rehabilitation, the highest was 5.93 m3/s, and the lowest was 3.21 m3/s with an intake of 32%, able to fulfill the planting pattern of paddy (100%)-paddy (100%)-paddy (100%), resulting in a production profit of IDR 83, 564,115,480.00 with the highest irrigation water requirement value of 3.10 m3/sec. Apart from that, the existing canal dimensions still meet the requirements after land reduction, so no changes to the canal dimensions are required.

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

The study of watershed morphology and land use patterns significantly affects hydrological processes and runoff coefficients, highlighting the quantitative nature of watershed characteristics. The Raya Watershed in West Kalimantan influences local communities and aims to enhance understanding of its physical attributes and hydrological dynamics through detailed analysis of topography, soil composition, land use, and river networks. Findings inform watershed management and conservation strategies. The analysis of the Raya Watershed, spanning 29,982.96 hectares (87.34% of total area) with elevations below 100 meters, reveals flat terrain vulnerable to flooding, particularly in low-lying or sea-level regions, exacerbated by limited natural drainage. Lower elevations support crucial wetland and floodplain ecosystems. Hydrological disruptions from land use changes and climate fluctuations can harm biodiversity and water quality. Effective land use planning is vital to address flood risk and environmental concerns, mitigating impacts like property damage and population displacement. Soil-type mapping informs conservation efforts, ensuring ecosystem resilience. Sustainable land management practices, guided by watershed characteristics like drain density and stream frequency, are essential to mitigate biodiversity loss and ecological imbalances.

Abstract

The study is centered on designing a 5000 KL Crude Palm Oil (CPO) Tank within Indonesia's palm oil industry, ensuring adherence to the API 650 13th Edition standard to effectively withstand operational and environmental loads. Plate theory, specifically the Kirchoff-Love theory, is employed to model structural components such as annular, shell, and roof plates, which must endure various loads including dead, internal (hydrostatic and pressure), external (wind, pressure, snow), live, and seismic loads as specified by API guidelines. Stress analysis is conducted to ensure compliance with material limits, utilizing ASTM A573M Grade 485 steel for plates and standard compressive strength for foundations.The research involves detailed phases encompassing data collection, preliminary design, structural modeling, loading analysis, stress assessment, weld design, and foundation planning utilizing SAP2000 software. Calculated stresses on tank plates remain well below API limits, confirming structural robustness. Welding details for butt and corner joints are carefully planned for durability, while deep pilings and pile caps provide stability against ground movements.By integrating empirical data and theoretical calculations, the study presents a comprehensive plan for constructing a dependable and cost-effective palm oil storage facility, thereby enhancing safety and efficiency within Indonesia's palm oil sector.
