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.","PeriodicalId":52838,"journal":{"name":"Jurnal Teknik Sipil","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2024-06-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141388718","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

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.

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.

Concrete specimens were prepared with varying silica fume content (0% to 20%) and subjected to rigorous testing using Compression Testing Machines (CTM). Results indicate a significant 55.91% increase in compressive strength with 10% silica fume, compared to conventional concrete. Beyond this optimal point, compressive strength diminishes due to reduced pore volume. Moreover, silica fume influences stress and strain characteristics, with higher maximum stress and strain observed in silica fume concrete. The research employs polynomial equations to model the stress-strain relationship post-peak stress, revealing valuable insights for concrete design and performance prediction.

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.
