Abstract

Integrating field rainfall data with satellite data improves data accuracy and overcomes rainfall data limitations for rain thresholds. Integration can involve field rainfall data, satellite rainfall data, or a different satellite dataset. Merging these rainfall data sources provides more spatial coverage of satellite data. To determine how well rainfall thresholds predict rainfall-triggered landslides, the threshold model must be validated. This study will evaluate satellite rainfall data before and after integration in developing a rainfall threshold model for landslide prediction in Badung Regency. To do so, the study used a cumulative rainfall threshold over 3, 7, 15, and 30 days and two rainfall satellite products (integrated merged multi-satellite retrievals (IMERG) and precipitation estimation from remotely sensed information using artificial neural networks (PERSIANN)). Median, first, and third quartiles were used to set thresholds. The area under the curve (AUC) was calculated to validate rainfall threshold outcomes using receiver operating characteristic (ROC) curves. Analysis showed that integrating satellite rainfall data into the rainfall threshold model for landslide prediction yields better results than other methods. An AUC value of 0.903 (90.3%) for the 30-day cumulative rainfall thresholds supports this claim. This model could be a good input for a landslide early warning system in Badung Regency.

Abstract

The information on land cover changes is very important in regional spatial planning. Remote sensing technology can minimize the cost and time in analyzing land cover changes. Normalized Difference Vegetation Index (NDVI) is a vegetation index that combines red and near-infrared channels so that it can provide approximate information about land cover in an area. The objective of this study is to extract land cover change information from Landsat 8 images based on NDVI values in Bangli Regency in 2015 and 2021. The classification method used to estimate the type of land cover is supervised classification. The results reveal the decrease of the land cover in the category of water body, sand, dry land/soil, rice fields, and vegetation, which are 1.62%, 14.14%, 7.93%, 8.63%, and 2.45%, respectively, while an increase in the settlement category by 30.12%. The overall accuracy of land cover classification result based on NDVI value is 86.54%.

Abstract

Gianyar Regency has many villages that can be relied upon as tourist destinations due to their cultural and natural potential. Kenderan Village has a natural atmosphere with vast stretches of rice fields and hills, which are the main attractions of this village. Various potentials can be developed through ecotourism concepts as tourist attractions. The development of tourist village infrastructure involves the arrangement of the area and environment to maintain its natural state, as well as the optimal development of other supporting tourist facilities that have not been utilized. The aim of this research is to identify the potentials in Kenderan Village (cultural, natural, and village potentials) and to determine the necessary infrastructure for the development of Kenderan Village as a tourist village. This study uses observation, interviews, and documentation as research techniques, employing the SWOT approach. The results of this research show that there are various tourism potentials that can be developed into various attractions and activities, which can be categorized into three types: natural potentials (rice fields, plantations, and natural beauty), cultural potentials (archaeological sites, Beji Telaga Waja, and Pura Griya Sakti Manuaba), and village potentials (Puri Agung Kenderan and traditional settlements). The development of tourism potentials in Kenderan Village is expected to provide optimal benefits for the local community, entrepreneurs, and the government in a sustainable manner, while contributing to environmental preservation.

Abstract

Integrated Water Resources Management (IWRM) is an essential approach for achieving the United Nations’ Sustainable Development Goals (SDGs), particularly Goal 6: “Clean Water and Sanitation.” This study explores the role of IWRM in supporting sustainable water management in Germany, a country renowned for its advanced environmental policies and innovative water management systems. By aligning with the European Union’s Water Framework Directive (WFD), Germany implements comprehensive strategies that integrate environmental protection, stakeholder collaboration, and transboundary water management. Key initiatives such as the Rhine River Restoration Project and the Danube Floodplain Restoration demonstrate Germany’s success in applying IWRM principles to improve water quality, restore ecosystems, and enhance flood resilience. Despite its progress, challenges remain, including agricultural runoff, industrial impacts, and climate change-induced risks. Recommendations for improving Germany’s IWRM include expanding data collection systems, strengthening pollution controls, promoting circular water economies, enhancing climate resilience, and increasing public engagement. Ultimately, Germany’s IWRM framework provides a model for sustainable water management globally, illustrating how collaborative governance, innovation, and adaptive strategies can support the achievement of SDG 6 and broader sustainable development objectives.

Abstract

Urban areas in Germany face increasing hydrological challenges due to climate change, extreme precipitation events, and the expansion of impervious surfaces. Traditional rainfall monitoring systems, such as rain gauges and radar networks, often fall short in capturing the spatiotemporal variability of urban precipitation, particularly in regions with complex topography or during high-intensity events. Satellite precipitation datasets such as IMERG, TRMM, CMORPH, GSMaP, and PERSIANN have emerged as essential tools for enhancing urban flood risk management. This paper evaluates the performance, limitations, and future prospects of these datasets in the context of Germany's urban environments. Key limitations include resolution constraints, latency, and accuracy issues related to orographic and winter precipitation. Nonetheless, recent advancements in machine learning, data fusion with ground-based systems like RADOLAN, IoT sensor integration, and downscaling techniques show significant promise in overcoming these challenges. The study highlights the potential of multi-sensor satellite systems and real-time data assimilation to improve predictive accuracy in urban hydrology. The findings emphasize the need for continued technological innovation and inter-operable data infrastructures to support climate-resilient urban water management strategies.

Abstract

Traffic congestion on Teuku Umar Barat Road is attributable to the road's location in the center of Denpasar, where there are very dense concentrations of shops. The purpose of this study is to analyze the performance of the Teuku Umar Barat road section in West Denpasar and to develop alternative solutions to address traffic congestion on the road. The method for calculating road section performance follows the Indonesian Road Capacity Guidelines 2023 to determine free-flow speed, capacity, and performance. The results of the analysis of the performance of the Teuku Umar Barat road section, with a 2/2 TT type of road, experienced performance problems with a degree of saturation value of 1.04, exceeding the road section performance eligibility requirements, which is ≤ 0.85, with the speed of passenger cars used being 26 Km/hour and the travel time used being 0.019 hours. After the implementation of traffic management, namely the implementation of the odd/even road system on the Teuku Umar Barat road from North to South and South to North, starting from the Marlboro intersection to the Gunung Salak intersection, the performance of the Teuku Umar Barat road improved with a decrease in the degree of saturation value to 0.48 and the speed of passenger cars used being 48 Km/hour. The travel time used with a segment length of 500 meters is 0.010 hours. The results of this study are expected to serve as a technical reference for local governments in the planning and management of traffic on urban road sections experiencing high levels of saturation.
