Abstract

Suburban areas often experience development pressures, with implications for changing green space into built areas, rural cultures into urban ones, and poverty into prosperity. The development of Buring Kampong (suburban settlement) in Malang City into a tourism kampong, in addition to improving the local economy, must also be able to support environmental quality and community independence. This research used the Asset Based Community Development (ABCD) approach in identifying tangible and intangible assets. The data were collected through field observation, focused group discussion, interviews, and secondary data. Tangible aspects include land use, natural and artificial resources, infrastructure, accessibility, machinery and equipment, and local architecture. Meanwhile, intangible assets include intellectual property, potential branding development, goodwill, software/web, formal and informal organization, social and cultural values, and potential customers. The data obtained were presented descriptively and discussed together, as a triangulation process. The results showed the diversity and breadth of tangible and intangible assets of Baran village, and both of these assets can be directly found in the field and during FGDs and interviews. This research is also an effort to strengthen community engagement and public awareness about their assets, and this activity needs to be continuously improved, to have a better level of community engagement, confidence, social participation, branding, and networking.

Abstract

Floods are natural occurrences with the potential to cause damage to ecosystems and pose significant threats to human life, resulting in the destruction of property, infrastructure, and socioeconomic challenges. In recent times, flooding in the Sub-Watershed of Bengawan Solo has been linked to the overflowing Kening River in Tuban County. Aim: This study aims to produce a flood susceptibility map to mitigate the frequency of flood occurrences as well as facilitate effective planning for flood disaster risk management. Methodology and results: Flood data is collected from 2016 to 2023 through field surveys, Sentinel-1 satellite imagery, and data from the Development Planning Agency, Tuban County. Integrating remote sensing data from satellite imagery (PlanetScope, Sentinel-2), geographic information systems (GIS), and spatial modeling techniques, a flood susceptibility map is developed for the Kening River catchment. The occurrence of floods in the Kening River area is associated with various factors (11 variables) assessed through the frequency ratio approach, including profil curvature, LS factor, aspect, rainfall, river distance, road distance, building density 100 m, road density 100 m, vegetation type, normalized difference water index (NDWI), and soil adjusted vegetation index (SAVI). The results show flood susceptibility maps utilizing frequency ratio (FR) and convolutional neural network (CNN) techniques. The flood susceptibility map obtained through the CNN method demonstrates a notably high AUC value. The model development generated a validation AUC value of 0.857 for training and 0.856 for testing. Conclusion, significance and impact study: This research provides an understanding into the factors that influence the occurrence of floods in the Kening River catchment area. It also emphasizes the benefit of advanced machine learning approaches in mapping the susceptibility of floods. Furthermore, this study has the potential to be helpful in guiding regional policy decisions and result in enhanced flood risk management measures in Tuban County.

Abstract

Law Number 32 of 2009 Article 57, paragraph 4C that one of the preservations of atmosphere functions regulate efforts to protect against acid rain. One of the effects of acid rain is soil damage to plants, such as what happened to paddy plants. In Indonesia, paddy is one of the priority food sources, but every year, it decreases in several regions. Aims: This study aimed at acid rain's anticipated impact on paddy plants in this case study Bandung Regency. Methodology and results: The approach method in this study is a normative juridical approach, using primary data sources obtained through interviews and journal literature. Then, secondary data from legal literature were analyzed descriptively and qualitatively. The study results show that the Bandung Regency Environmental Service has enforced the law. However, violations still occur by industry and society through vehicle emissions, coupled with the increase in population. One of the efforts to formulate policies to anticipate acid rain in paddy plants is to establish sanctions for violators who still pollute the environment, apply catalytic converters to vehicle exhausts that have the potential to remove NOx, carry out measurements at groundwater measurement stations, water quality information systems (manual or real-time). In addition, the irrigation policy for river water flowing on agricultural land with existing laws is being improved. Conclusion, significance, and impact study: Anticipating the impact of acid rain on rice requires various approaches, both technical and non-technical, as well as further analysis from various policy sectors.

Abstract

The high mobility of sub-urban communities has become the focus of the government to create an effective transportation system by creating a Transit-Oriented Development concept at several stations in sub-urban or supporting cities of DKI Jakarta. Aims: The purpose of this research is to find out whether the Bekasi and Plawad stations which are located in the suburbs are effective for making transit oriented development. Methodology and results: The type of research to be carried out is quantitative and qualitative research, in which the variables in this study will cover the area, the distance between points, the number of trips from each region to the types of transportation modes used by the community. Then, these variables will be analyzed spatially using maps created in the ArcGIS application and compared to be given a score (scoring) in accordance with the provisions of the indicators of the variables that have been determined in this study. Conclusion, significance and impact study: Plawad and Bekasi Stations are considered not feasible to be used as TOD due to inadequate facilities, the train itself is not yet the main transportation and needs to be increased to meet the commuter mobility needs of the people of Bekasi City.

Abstract

Solar desalination technology has been one of the effective solutions to tackle the problem of water scarcity. A number of studies have been conducted at our water research group to determine which variable influences the quantity of distilled water produced by an independent solar desalination unit. Aims: This study was aimed to design and optimize a novel solar desalination unit and field-tested using the best variable from the previous studies. Methodology and results: Variables used from the previous studies were evaluated to obtain the best values for each parameter, those are: glass cover inclination, gap distance between water and glass cover, insulation thickness, water depth, and water mass flow rate. Those best values were then implemented in the optimized basin design, delivery mechanisms, evaporation techniques, and heat isolation methods. The optimized design can generate up to 2,778.2 mL/m2/8hrs of distilled water with an efficiency of 23.35% in preliminary test, and was field tested at Batukaras Beach, where it produced up to 902 mL/m2/8hrs with an efficiency of 13.56%. Conclusion, significance and impact study: Meteorological parameters and environmental conditions are important factors that greatly affect the performance and productivity of the desalination unit. The relative humidity is inversely proportional to the volume of distillate water, where the smaller the value, the greater the amount of distillate water that can be produced, and it has significant impact on the productivity of the prototype. The quality of the distillate water produced still needs improvement on the parameters of pH, turbidity, and total coliform.

Abstract

This study aims to investigate the mechanical properties of lightweight concrete using lightweight aggregate and analyze the impact of silica fume on enhancing its compressive strength. The main objective of this study was to improve the value of industrial waste by utilizing GGBFS as a substitute for cement. Four alternative compositions have been used to produce samples of lightweight concrete. The coarse aggregate is substituted with 100% lightweight expanded clay aggregate, whereas the fine aggregates are replaced with 100% vermiculite and 100% polystyrene bead waste.                                A combination of 20% GGBFS and 10% silica fume is employed for cement replacement. The materials used throughout this study consist of aluminum powder and superplasticizer. The workability, compressive strength, tensile strength, and specific gravity of concrete will be determined by testing.                  The waster curing will be carried out on cylindrical concrete specimens 200 mm in height and 100 mm in diameter. Experimental results showed that the concrete mixture consisting of 80% cement and 20% GGBFS as binders, along with lightweight expanded clay aggregate as coarse aggregate and vermiculite as the fine aggregate, exhibits the highest compressive strength compared to other lightweight concrete mixtures.
