Abstract

Based on the WHO data updated on December 28, 2021, the global tally of COVID-19 cases for that year reached 281,808,270, with a reported 5,411,759 deaths worldwide. Specifically in Indonesia, the cases total 5,411,759, with 144,081 deaths by that date. To reduce the risk of transmission, practicing good hand hygiene is crucial. Regular hand washing with soap and water or using an alcohol-based hand sanitizer when soap isn't available helps remove pathogens from our hands, contributing to a cleaner and healthier lifestyle. Collecting rainwater in specially designed containers can be an effective and sustainable way to meet handwashing needs, supporting health protocols to prevent the spread of COVID-19. By providing an accessible water source for hand hygiene, communities, especially those with limited water access, can implement handwashing practices more consistently. This initiative is beneficial for promoting both environmental sustainability and public health, particularly in areas facing water scarcity. Additionally, filtration or disinfection processes can enhance rainwater collection systems to ensure safe water for handwashing, further supporting a cleaner and healthier environment.  The result is that visitors wash their hands on average 5 times per day, with an average volume of 0.6 liters of water used in a one-time hand wash. With an interval of 6 days without rain, the maximum hand washing needs are 53.35 m3. The roof area in the market is 16,240 m2, and the water volume from effective rain is 21.11 m3. If we use a reservoir of 1200 liters, we need 22 22-unit reservoirs for maximum water demand.

Abstract

The Ministry of Forestry has designated the Way Rarem sub-watershed, part of Tulang Bawang, a critical watershed, as a priority. Several reasons cause land criticality, including deforestation and inappropriate land use, which cause erosion and sedimentation. In this case, the criticality of the watershed occurs due to the high erosion rate, which impacts flooding in the Way Rarem subwatershed area. Over the past year, there have been flood disasters at five points in the Tulang Bawang watershed. Based on information from BNPB (National Disaster Management Agency), the flood disaster affected 140 families. The losses that occur due to flooding that arise due to erosion and sedimentation need to be studied in more depth; therefore, the situation in the Way Rarem Sub-watershed is important to study further. The objectives of this study are to determine the Erosion Hazard Index, measure the erosion rate in the Way Rarem sub-watershed using the USLE method, and provide adequate conservation strategies. The required data are rainfall data, soil type, slope, and land use in 2019 and 2023 as a comparison. GIS was used to process all the data. The results showed that the erosion rate in 2019 was 21933.9 tons/ha/year, whereas in 2023, it was 14187.4 tons/ha/year, with the Erosion Hazard Index dominated by the 'Very High' category. For conservation direction, three alternative conservation activities are carried out, namely by vegetative, mechanical, and vegetative-mechanical methods. Based on the results of the analysis, the appropriate conservation direction to reduce the erosion rate is vegetative-mechanical conservation, which can reduce the erosion rate by 66.9% of the existing erosion rate. From the results obtained, it is hoped that new concepts in land conservation that have not yet been implemented in the Way Rarem Sub-watershed can be taken into consideration. Combining two conservation methods, vegetative and mechanical, can be an alternative to controlling erosion that occurs in the Way Rarem Sub-watershed.

Abstract

Way Sekampung subwatershed is the watershed area of Way Sekampung dam. The changes in land use that occurred in the Way Sekampung subwatershed caused flooding and landslides. To reduce existing problems, vegetative and mechanical land conservation efforts are needed. In this study, the USLE method was used to estimate the rate of erosion and then map the distribution of the Erosion Hazard Index in the Way Sekampung Subwatershed with the help of Geographic Information System (GIS). Based on existing conditions, the erosion rate in 2017 was 29626.262 tons/ha/year; in 2022, the erosion rate was 76617.579 tons/ha/year. The results of the analysis of the Erosion Hazard Index in 2017 and 2022 showed four criteria, namely low with a difference of -1.115%, moderate with an increase of 1.140%, high with a difference of -0.097%, and very high with a difference of 0.071%. Conservation with new land use, construction of terraces, and check dams has resulted in a reduction in erosion in the Way Sekampung Subwatershed with an Erosion Hazard Index, which is a low index increase of 26.992% from the existing condition and a very high 22.819% reduction from the existing condition. These results show that land conservation can reduce erosion in the Way Sekampung Subwatershed.

Abstract

Sade Village displays a unique settlement pattern that is influenced by geographical conditions and the needs of its residents. One of the buildings that follows the contour of Sade Village is Bale Tani, a medium-sized bale generally inhabited by families with a middle economic level. Bale Tani has undergone several changes due to the wishes of its residents, which have the potential to influence the sustainability of its vernacular architecture. This research aims to analyze the sustainability of Bale Tani vernacular architecture in Sade Village using the Multidimensional Scaling (MDS) method through the RAPFISH application, as well as carry out leverage analysis to identify indicators that influence sustainability. The results of the analysis show that the overall level of sustainability of the Bale Tani vernacular architecture is less than satisfactory, with a sustainability index value reaching 47.64%. Each of the analyzed dimensions, such as visual image, climate responsiveness, and comfortable living space, shows a low level of sustainability. Of the 18 indicators observed, nine indicators, including kamar dedare, kamar dengan to’aq, roof sheathing, wall sheathing, window openings, building floor, floor plan, roof, and wall, are the dominant factors in the sustainability of Bale Tani vernacular architecture.

Abstract

Jodipan Colorful Village, originally a slum, has transformed into a popular tourist destination. This study investigates how the physical arrangement of the settlement mass and its thermal environment affect the comfort of activities in the road corridor, a critical public space utilized by both visitors and residents for tourism, commerce, and interaction. The research aims to analyze the relationship between the spatial configuration of the buildings and the thermal conditions of the area, particularly in this densely populated riverside village. Utilizing visual techniques, the study formulates criteria for the spatial arrangement of settlements, focusing on the balance of solids and voids in the layout. Thermal environment measurements are conducted to assess air temperature and humidity along the road corridor. The findings indicate that the spatial arrangement significantly impacts the thermal environment. Factors such as building density, corridor width, and proximity to the river influence temperature and humidity levels, with closer proximity to the river correlating with higher humidity and lower temperatures. These results provide insights into optimizing public space design in high-density urban environments, particularly in similar riverside settlements.

Abstract

This paper presents a case study on a slab bottom grouting project, focusing on the development and optimization of an underplate grouting model. The primary research objective is to determine the optimal grouting implementation strategy for the project by analyzing the impact of various structural parameters, grout properties, and grouting process properties on the grouting radius. The model incorporates the Brinkman equation and the level set method to explore the impact of various structural parameters, grout properties, and grouting process properties on the grouting radius. Through extensive analysis, the paper identifies the optimal implementation strategy for the project. The study reveals that parameters such as subbase permeability (K2), grouting pressure (P), and grouting time (t) positively affect the grouting radius, while the grout viscosity (μg) has a negative impact. The influence of grout density (ρg) and displaced fluid density (ρa, ρw) on the grouting radius is found to be negligible. Based on the underplate grouting model, the paper determines the optimal grouting implementation scheme for the slab bottom grouting project, specifying a grouting pressure of 1.2 MPa and a grouting time of 60 seconds. Furthermore, the effectiveness of the proposed implementation strategy is indirectly validated through the Falling Weight Deflectometer (FWD) analysis. The results demonstrate that the underplate grouting model successfully eliminates voids at the bottom of the slab, providing conclusive evidence for the reliability of the grouting strategy proposed by the model. Overall, this study contributes to the understanding and optimization of slab bottom grouting projects, offering valuable insights for practitioners in the field.

Abstract

This study explores the adoption and effects of innovative materials and advanced technologies on sustainable construction practices in Nigeria. Employing a mixed-methods approach, the research integrates quantitative surveys and qualitative interviews to collect comprehensive data from 255 construction professionals, achieving an 85% response rate. The findings indicate that recycled materials and green concrete are the most frequently utilized innovative materials, primarily due to their environmental advantages and cost-effectiveness. Building Information Modeling (BIM) and prefabrication emerge as the most widely adopted advanced technologies, enhancing efficiency, reducing waste, and improving project quality. Additionally, regression analysis reveals the complex nature of adopting sustainable construction practices, with cost emerging as a significant barrier for many firms. Despite these positive developments, challenges such as high initial costs, lack of awareness, insufficient regulatory support, and limited availability of sustainable materials impede wider adoption. The study highlights the necessity for targeted interventions, including financial incentives, stronger regulatory frameworks, and comprehensive education and training programs, to foster sustainable construction practices. The findings have substantial implications for policymakers, industry professionals, and researchers, offering a foundation for future research and practical strategies to advance sustainability in Nigeria's construction sector.

Abstract

The urban heat island (UHI) phenomenon has been detected in Malang City, defined as an urban area with a higher surface temperature than its surrounding areas. Pasar Besar Corridor is the center of trade and services as well as the Central Business District (CBD) of Malang City, located in Sukoharjo Sub-District, Klojen District. Although it is an economically strategic area in Malang City, Pasar Besar Corridor is vulnerable to high-intensity UHI exposure, so it is necessary to conduct a study related to the UHI phenomenon. This research aims to compare the results of UHI analysis between macro-scale and micro-scale analysis. Macro-scale UHI analysis was performed using Landsat-8 data as input for Land Surface Temperature (LST), while micro-scale UHI analysis utilized UAV thermal imaging. The results of the analysis show that while Pasar Besar Corridor is not considered a hot spot in Sukoharjo Village at the macro-scale level, a micro-scale UHI has occurred in Pasar Besar Corridor, with the roads being the hot spot, or “heat islands," reaching 48.62 °C. There is a significant difference between the highest temperature from UAV thermal imaging and LST, caused by the differences in resolution and altitude between Landsat-8 data and UAV data. From this research, it is concluded that LST is more suitable for larger study areas, while UAV thermal imaging is better suited for small-scale and more detailed analysis. However, each tool has its limitations, such as lower detailed accuracy for LST and higher costs for UAV thermal imaging.

Abstract

Trucuk Subdistrict in Bojonegoro Regency, Indonesia, possesses considerable agricultural potential, yet its productivity remains limited due to inefficient irrigation systems. Damaged irrigation networks have led to inadequate water distribution, which indicates the importance of effective operation and maintenance strategies. This study aims to assess the existing condition of the Trucuk Irrigation Area (DI Trucuk) and determine management priorities to ensure a reliable water supply for agricultural land. A quantitative approach was employed using evaluative and management priority analysis, focusing on key irrigation components such as main buildings, control buildings, and secondary and tertiary canals. The results reveal that several irrigation channels, particularly GYN-5 and SRK-12, are severely damaged, with respective damage scores of 0.46 and 0.42. Although some channels, including GYN-5, SRK-12, and GYN-2, recorded the highest functional values, they were still poorly functioning. Based on a priority analysis, rehabilitation of GYN-5, GYN-2, SRK-12, and SRK-11 is recommended. Additionally, routine and regular maintenance of other irrigation channels and buildings is needed to ensure efficient and effective water distribution to agricultural areas. The proposed management plan offers a practical solution to improve irrigation performance and supports sustainable agrarian productivity in Trucuk Subdistrict.

Abstract

The performance-based concept for earthquake-resistant buildings must be considered in the structural design of buildings. This concept analyzes the structural components to observe how the structure behaves during an earthquake, ensuring the building can withstand it safely. This study used pushover analysis to compare the performance of buildings with and without shear walls. The building's structure was constructed using three different types of modeling. The results showed that type 1 buildings have greater displacement and story drift values than type 2 and type 3. This finding suggests that type 2 and type 3 buildings had better structural rigidity than type 1. The plastic hinge mechanism in type 1 buildings refers to the SCWB design concept, where the plastic hinge mechanism occurs on the beam, whereas in type 2 and type 3 buildings, the plastic hinge machinery occurs in the shear wall area. Performance levels in types 1, 2, and 3, which use the FEMA 356 method, are at the immediate occupancy performance level.
