Abstract

Amphibious aircraft are types of aircraft that can land on land and in water with floating components (floaters).  Amphibious aircraft are capable of landing both on land and water using float-equipped structures. In its operation, it is likely to have a bending force on the floater. When the floater is replaced with a hybrid composite, it is likely to have a light load and high beding value bending value. During operation, the floater is subjected to significant bending forces. Replacing the floater with a hybrid composite results in a lighter structure with improved bending strength. This study aims to analyze the bending test of hybrid composites reinforced with carbon fiber and aluminum faceplates. This study aims to evaluate the bending strength of hybrid composites reinforced with carbon fiber and aluminum faceplates. The method used in this study is vacuum bagging, where the sample is combined with epoxy resin and mixed with carbon nanotube (CNT) nanoparticles and aluminum powder (AL). The study was conducted with adhesive resin, surface treatment and the addition of nano particles to determine the effect of the bending strength of the composite. This study aims to analyze the effect of surface treatment and nanoparticle addition on the flexural strength of the hybrid composite.  The results showed that had a high bending value compared to the variation of specimens without surface treatment or nano particles. Specimens treated with surface modification and nanoparticles exhibited higher bending strength than those without either treatment. The highest bending stress value was obtained by the CNT variation of 133.89 MPa followed by the variation without nano particles of 98.59 MPa, then the variation without surface treatment of 91.76 MPa, and the one with the smallest value was the AL variation of 61.02 MPa. Macro photo analysis after bending test shows the presence of Mixed-mode defects in the specimen. This shows that specimens that have surface treatment and nano particles have better bonds and are able to fill the void in the empty area, so that the bending strength is good. This study provides an important contribution to understanding the variation of adhesives and nano particles on the bending strength of hybrid composites. This study offers preliminary insights into how variations in adhesives and nanoparticles influence the bending strength of a specific hybrid composite system.

Abstract

The iron and steel industry constitutes one of the strategic pillars of economic development. However, it is also a major contributor to global air pollution due to high-temperature fossil fuel combustion inherent in its processes. This study aims to analyze the wind characteristics surrounding a steel and iron industrial facility in North Sumatra and to predict the areas most at risk from pollutant dispersion. Meteorological data from the NASA POWER Project database, covering the period from 2021 to 2024, were processed to examine local wind profiles across two distinct seasonal periods—rainy and dry. The analysis revealed that during the rainy season, winds predominantly originated from the northwest, with moderate speeds ranging from 2.10 to 3.60 m/s, leading to pollutant dispersion mainly toward the southeast (145°, 40%). Conversely, in the dry season, wind direction was more variable, as indicated by a low resultant vector percentage (11%), suggesting multidirectional pollutant spread. Across both seasons, the majority of wind speeds were below 2.10 m/s, which limits vertical atmospheric mixing and enhances pollutant retention near the surface. Air stagnation, particularly during transitional periods between seasons and under temperature inversion conditions, further intensifies pollutant accumulation. These findings underscore the critical role of seasonal wind dynamics in air pollution behavior and provide a scientific foundation for developing effective mitigation strategies. Practical policy implications include the establishment of buffer zones in downwind residential or agricultural areas, the implementation of stricter emission controls during periods of low wind speed and stagnation, and the integration of local wind data into early warning systems for air quality. Such measures are essential to protect public health, especially in high-density areas surrounding PT X, including Medan City, Deli Serdang Regency, Serdang Bedagai Regency, and Tebing Tinggi City.

Abstract

The problem of waste transportation is a major challenge in waste management in Salatiga City. With the amount of daily waste generated reaching 457.81 m³ and the volume transported only around 327.33 m³, the level of waste transportation has only reached 71.72%. This study aims to evaluate and optimize the current waste transportation route through a spatial approach using QGIS software. The methods used include field observation, primary and secondary data collection, and spatial analysis of the distribution of routes and workloads of the transport fleet consisting of 9 arm roll units and 1 dump truck unit, with a total average daily trip of 58 trips. The results of the comparison between the existing route and the planned route show a daily route length efficiency of 10.57 km (1.15%), fuel consumption savings of 2.73 liters per day, and travel time efficiency of 25 minutes. The volume of transported waste also increased from 83,730 kg/day to 89,500 kg/day (up 6.89%), which was achieved through more optimal route planning, additional trips to TPS Boja and Tingkir, and equalizing the workload between drivers. The results of this study confirm that GIS-based route optimization can increase the efficiency of distance, fuel, time, and productivity of the waste transportation system as a whole in Salatiga City.

Abstract

This study focuses on optimizing biofiltration techniques to mitigate heavy metal contamination in urban wastewater. The increasing presence of heavy metals in wastewater, particularly in urban environments, poses a significant threat to both human health and ecosystem stability. Biofiltration, a natural remediation process utilizing living organisms, has gained attention as an effective method for removing heavy metals from contaminated water. The research combines experimental analysis with a comprehensive literature review to evaluate and enhance the performance of various biofiltration systems. By examining the influence of different variables, such as plant species, soil composition, flow rate, and pollutant concentration, on the efficiency of heavy metal removal, this study provides a broad perspective on the potential applications of biofiltration. Experimental analysis of biofilter setups demonstrated that specific plant-microbe interactions and substrate types significantly enhance the absorption and accumulation of toxic metals. The literature review further supports these findings by summarizing past studies and providing insights into existing biofiltration techniques, their effectiveness, and limitations. The study's findings indicate that optimized biofiltration can serve as a sustainable and cost-effective solution for urban wastewater management. By providing a detailed understanding of how biofilters can be adapted and scaled for urban applications, the research contributes to the development of environmentally friendly wastewater treatment technologies. The results underscore the importance of integrating biofiltration systems into urban water management strategies for improving water quality and reducing environmental pollution.

Abstract

This study aims to analyze the actual irrigation water losses in the Jimat Irrigation Area, identify the factors causing irrigation water losses, and determine effective strategies to reduce water losses in the area. One of the important irrigation areas in this region is the Jimat Irrigation Area, which supplies water to 110 hectares of agricultural land. However, the effectiveness of water distribution is often hampered by significant water losses. The research methods used are descriptive evaluative and quantitative descriptive analysis. The descriptive evaluative method describes a study that evaluates the actual conditions of the study object. Meanwhile, the quantitative descriptive analysis method aims to accurately describe the characteristics of the study object.Based on the analysis and calculations, the Jimat Irrigation Area requires an actual irrigation water supply of 0.812 m³/second to serve its four tertiary canals, with the highest allocation going to Tertiary Channel 2 (0.465 m³/second) and the lowest to Tertiary Channel 4 (0.084 m³/second). However, only 54% of the initial discharge of the primary canal (1.702 m³/second at the Upstream Intake) actually reaches the agricultural land. A total of 46% of the water (0.686 m³/second) is lost along the primary network, with seepage accounting for 99.94% of the water loss, particularly in critical sections such as Primary Channel V, which lost 59% of its discharge. Meanwhile, the contribution of evaporation is minimal (0.06%) due to the limited water surface area and low daily evaporation rate (2.76 mm/day).

Abstract

This study assesses the effectiveness of solar orientation and shading devices in reducing cooling loads in educational buildings through a qualitative literature review approach. As educational facilities are significant energy consumers, especially in hot climates, optimizing building orientation and integrating passive shading strategies are crucial for enhancing energy efficiency and thermal comfort. The literature indicates that building orientation significantly influences solar heat gain, with north-facing orientations generally resulting in lower internal temperatures and reduced cooling demands compared to east or west-facing layouts. Shading devices, including fixed external shades and optimized window-to-wall ratios, further mitigate direct solar radiation, contributing to notable reductions in annual energy consumption. Studies reviewed demonstrate that the combination of optimal orientation and well-designed shading can decrease cooling loads by 11% to 23%, and overall energy use by up to 44%. However, the effectiveness of shading devices depends on their design, placement, and integration with other passive strategies. While fixed shading reduces solar gains, occasional glare and insufficient daylight distribution may persist, indicating the need for a holistic design approach. The findings underscore the importance of integrating solar orientation and shading devices in the early design phase of educational buildings to achieve sustainable, energy-efficient, and comfortable learning environments. This research provides valuable insights for architects, planners, and policymakers seeking to implement best practices in sustainable school design, particularly in regions with high cooling demands.
