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.

Makalah ini membahas PentaPod adalah sejenis armor baru dari beton yang dirancang untuk melindungi bangunan pantai dari kerusakan akibat gelombang dan arus laut. PentaPod dikembangkan untuk mengatasi keterbatasan dari armor beton yang umum digunakan pada struktur pantai, yang hanya dapat disusun secara acak atau teratur namun dipasang tanpa terikat satu sama lain, menyebabkan stabilitas keseluruhan bangunan pantai yang dilindungi sangat tergantung pada stabilitas individu dari setiap unit armor. Armor Beton PentaPod dapat disusun secara acak dan teratur serta dapat diikatkan satu sama lain. Namun, PentaPod juga dapat dipasang secara teratur dalam satu atau beberapa lapisan, di mana seluruh unit armor saling terikat secara horizontal dan vertikal sehingga stabilitas keseluruhan bangunan pantai tergantung pada stabilitas gabungan unit-unit armor yang terikat. Dalam makalah ini ditunjukkn hasil penguhian Koefisien Stabilitas (Kd) untuk dua varian dari armor beton PentaPod, yaitu PentaCone dan PentaOcta, yang diuji di Tangki Gelombang. Studi ini menunjukkan koefisien stabilitas untuk kedua varian dari Armor Beton PentaPod. Namun, pengujian untuk Armor PentaPod yang saling terikat, yang diharapkan membentuk sistem yang sangat stabil, belum dilakukan. Kebaruan penelitian ini terletak pada kemampuan untuk memasang armor beton secara acak dan teratur, mengurangi biaya dengan mengurangi jumlah dan ukuran unit armor sambil meningkatkan stabilitas dari armor beton yang terhubung, serta memudahkan pemasangan di permukaan dan dalam air.

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.

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.

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.

This case study investigates the distribution patterns of goods transport vehicles on Jalan Khatulistiwa, focusing on the UPPKB Siantan weighbridge in Pontianak. Urban centers are crucial in goods distribution and act as nodes connecting hinterland areas. Urban sprawl necessitates longer commutes as cities grow and exacerbates peak-hour traffic congestion. Identifying and understanding movement patterns using Origin-Destination Matrices (ODM) is essential for optimizing transportation policies and economic development.The study employs a mixed-method approach to collect primary data through field surveys, mapping the movement of goods and transport vehicles from origin to destination. Given their significance in urban freight movement, land transportation and hefty vehicle traffic is the primary focus. The analysis includes delineating Origin-Destination Matrices (ODMs) to assess traffic flows and identify critical routes and distribution nodes. Insights from this study inform transportation planning strategies to enhance efficiency, reliability, and sustainability of goods movement within Pontianak.Through detailed data collection and analysis, this research aims to contribute practical insights for policymakers and urban planners to improve traffic management and enhance the overall transportation network's performance in Pontianak, ultimately supporting economic growth and development.

This study investigates the stress-strain relationship of concrete with silica fume used as a partial replacement for cement, aiming to enhance concrete quality and durability. Silica fume, acting as a cement substitute, fills voids between cement particles, reducing pore size and enhancing concrete properties. 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. This study underscores the importance of silica fume as a beneficial additive, contributing to concrete strength and durability. Further investigation is needed to fully understand the mechanical properties and optimize the use of silica fume in concrete construction, ensuring improved performance and longevity of concrete structures.

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.
非法采金是指在没有获得政府或主管部门正式许可的情况下开采黄金。它给印度尼西亚本卡扬地区带来了重大的环境和地质挑战。本研究分析了 Bengkayang 地区 Kinande 村无证开采金矿造成的斜坡稳定性。假设圆形滑坡面不受地震影响，本研究使用手动费勒尼乌斯计算和 Geo Studio/Geo Slope 2023 软件确定潜在滑坡的安全系数 (SF)。壤土的内聚力大，但内摩擦力小，因此容易失稳。砂土缺乏内聚力，依靠颗粒摩擦。内聚力 (c) 和内摩擦角 (φ) 等剪切强度参数是评估斜坡稳定性的关键。研究采用费勒尼乌斯法和 Geo Studio 2023 软件来分析斜坡稳定性，安全系数（SF）结果显示了潜在的危险。平原地区的采矿显示出良好的 SF 值（大于 1.5），表明活动安全。相反，在山区和水道地区采矿的 SF 值较低 (<1.5)，表明存在不稳定性和安全风险。建议包括分层采矿实践，以保持稳定的斜坡，确保采矿者的安全。这项研究有助于了解地质灾害，并提出加强矿区安全、环境可持续性和监管治理的措施。了解和分析这些因素对于岩土工程的稳定性和安全性至关重要，可确保边坡稳定所需的剪应力和剪切强度的平衡。
