Aceh Tamiang Regency is an area with a high risk of annual flooding. This emergency condition often triggers a surge in environment-related diseases such as skin diseases, respiratory infections, and diarrhea. The success of managing health crises heavily depends on pharmaceutical logistics management, especially the availability of essential medicines and ease of access for refugees at evacuation points. This study aims to analyze the extent of medicine availability at community health centers and health posts, as well as to evaluate the barriers to medicine accessibility for flood victims in Aceh Tamiang Regency. This study uses a qualitative/quantitative descriptive method (choose one) with a case study approach. Primary data were collected through in-depth interviews with pharmaceutical logistics officers and surveys of flood survivors. Secondary data were obtained from the drug stock reports of the Aceh Tamiang District Health Office. Analysis was conducted on variables such as drug types, stock amounts (Buffer Stock), and distribution channels during the emergency response period. The results of the study indicate that the availability of drugs in the initial disaster phase tends to be (state the prediction, e.g., sufficient/limited). However, accessibility is often hindered by damaged road infrastructure and uneven distribution to remote posts. There is an urgent need to strengthen the logistics early warning system so that the types of medicines available match the disease patterns that emerge after floods. Although medicine stocks are generally available in central pharmacy warehouses, geographical constraints and distribution coordination are the main factors hindering accessibility. It is recommended that local governments map out alternative distribution routes and provide disaster-specific buffer stock of medicines at the sub-district level.

The increasing demand for low latency and high-throughput multimedia applications has spurred significant advancements in hardware software co design. This study explores the integration of custom digital signal processing (DSP) hardware accelerators with optimized software frameworks to enhance deep learning accelerated DSP tasks.

This research examines the coordination efforts of the Karanganyar District Disaster Management Agency (BPBD) in managing disasters, identifying obstacles, and exploring efforts to strengthen these coordination efforts. Utilizing a qualitative approach with a case study method, the study aims to investigate the mechanisms of cross-sector coordination, communication patterns, and division of labor within BPBD. Data was gathered through in-depth interviews, observations, and document studies, and analyzed using an interactive model. The findings indicate that BPBD's coordination is relatively effective, demonstrated through unified action, a multi-channel communication system, and a clear division of labor. However, challenges remain, including the complexity of cross-sectoral coordination, differences in capacity and authority, and the pressure of emergency situations. The study concludes that improving coordination requires enhancing staff discipline, developing human resource capacity, and strengthening an integrated work system. These efforts are vital for improving the overall effectiveness of disaster management at the local level, ensuring a more efficient and comprehensive response to disasters in the future.

Banda Aceh City has high vulnerability to tsunamis due to its coastal location directly facing the sea and being situated in an active tectonic zone. This study evaluates the spatial distribution of tsunami risk and assesses coastal conditions as disaster mitigation efforts using a mixed-method approach that combines quantitative analysis based on Geographic Information Systems (GIS) and qualitative analysis through field surveys and expert assessments. Three beaches were selected as study locations: Ulee Lheue Beach, Syiah Kuala Beach, and Alue Naga Beach, with risk assessment calculated using the formula Risk = (H × V) / C according to the BNPB framework and overlay techniques in GIS to create risk distribution maps. Coastal condition evaluation focused on coastal vegetation and protective coastal structures assessed using an ordinal scale of 1–5. Results show that Ulee Lheue Beach has the highest mitigation capacity with a score of 64.5% (good category), Syiah Kuala Beach reaches 57.5% (fairly good), while Alue Naga Beach has the lowest score of 28.3% (poor). Correlation analysis yielded a coefficient of r = 0.97, indicating a very strong positive relationship between coastal vegetation and protective coastal structures. Therefore, the study recommends strengthening mitigation strategies through improved protective infrastructure and optimization of coastal vegetation functions, particularly in high-risk areas, to reduce tsunami impacts in the future.

Multatuli Area 4 is highly susceptible to flooding due to its close location to the Deli River and inadequate environmental management, which exacerbate the risk during the rainy season. Despite this vulnerability, community preparedness remains limited, leaving residents exposed to potential damage and loss. This study employed a descriptive qualitative approach, collecting data through in-depth interviews and direct observations with purposively selected informants who have knowledge of local flooding experiences. The findings reveal that while residents are generally able to recognize early signs of flooding, their responses are largely reactive rather than proactive. Several factors contribute to this low level of preparedness, including limited perception of risk, insufficient economic capacity to implement preventive measures, declining social cohesion and cooperation, and underutilization of available mitigation facilities and infrastructure. These conditions highlight the need for improved community awareness, better access to resources, and strengthened disaster management strategies to enhance flood preparedness in Multatuli Area 4.

The flood disaster that hit Medan City caused a multidimensional impact on the community, especially the psychological impact experienced by the victims. In addition to material losses, flood victims often face emotional distress in the form of anxiety, stress, trauma, and a sense of loss. This study aims to examine the role and effectiveness of individual counseling in dealing with the psychological problems of post-flood victims. The research method uses a qualitative approach with case studies through in-depth interviews, observations, and documentation of victims who receive individual counseling services. The results show that individual counseling plays an important role in helping victims understand their emotional state, manage stress, and rebuild hope and resilience after disasters. Individualized counseling also provides a safe space for victims to express their feelings, gain support, and develop adaptive strategies in dealing with trauma. These findings confirm that psychological interventions based on individual counseling can be one of the effective approaches in disaster victim recovery, especially floods, so that it can strengthen psychosocial aspects and improve the quality of life after disasters. Thus, this research contributes to the development of more responsive and sustainable counseling services in the context of disaster management in Indonesia.

The flood disaster the struct Mauponggo, Flores, Est Nusa tenggara, not only caused infrastructural destruction, loss of life and social trauma, but also revealed a deeper philosophical dimension of human existence. From an ontological prespective, a disaster is not merely a natural occurrence but a moment of disclosure that unvieils the existential fragility of human beings in the faceof natural forces beyond rational, technological, and social control. Onology, as a branch of metaphysics that explores the nature of being, understands humans as beings whose existence is inseparable from space, time, and limitation. Trough a reflective and literature based approach, this study examines the Mauponggo flood as an existential event that exposes the ontological condition of humanity, drawing particularly on Martin Heidegger’s concepts of being toward death and being in the world. The finding show that disaster reveals humans as finite and vulnerable beings who remain open to relationships with nature, others, and the transcendent. This study affirms that an ontological prespective on disaster not only enriches academic discussions on the philosophy of disaster but also holds practical signifincace. The awareness of existential fragility encourages social solidarity, ecological ethics, and deeper transcendental reflection. Thus, this work contributes to developing more reflective and meaningful humanitarian and sustainability responses rooted in a philosophical understanding of human existence and its place in the world.

The traditional homes of indigenous communities in Indonesia are highly vulnerable to natural disasters, particularly earthquakes, due to Indonesia's location in the Pacific Ring of Fire, which experiences high seismic activity. This situation demands the strengthening of traditional buildings to withstand potential earthquakes. Stilt houses, as a form of traditional architecture, possess characteristics that actually support earthquake resilience, such as flexible structures, the use of lightweight materials, and the application of local wisdom passed down through generations. With the development of modern construction techniques, stilt houses have the potential to become safer and more adaptable dwellings to earthquake shocks. However, indigenous communities, particularly those living in earthquake-prone areas and with lower levels of education, often face limited knowledge and skills related to the basic principles of earthquake-resistant construction. This lack of understanding results in traditional house construction without considering structural safety aspects, ultimately increasing the risk of serious damage and even collapse during an earthquake. These impacts not only threaten life but also cause significant material losses. This community service activity aims to improve the preparedness and resilience of the Sentani Indigenous community by developing earthquake-resistant stilt house models, increasing knowledge and skills in earthquake-safe house construction and maintenance, and encouraging the use of innovative technology and materials. The expected outcomes are the creation of model houses that can serve as examples and the dissemination of information on earthquake-resistant construction technology.

Flash floods are a hydrometeorological disaster that frequently strikes Indonesia, including East Aceh. Their impacts include not only physical damage but also social and economic disruption to residents. This article describes a community service activity involving the distribution of community donations to flash flood survivors in Pante Bidari District. Using a descriptive qualitative approach, this article analyzes the process of collecting, managing, and distributing aid and links it to theoretical findings in the scientific literature on disaster management, social solidarity, and community resilience. The literature review indicates that local community involvement significantly influences the effectiveness of disaster management (Hariyal & Anhar, 2015); (Faiz, 2025) The results of this activity indicate that community-based aid distribution can accelerate the fulfillment of basic needs, strengthen social networks, and increase the social resilience of affected communities. Thus, this activity confirms that strengthening solidarity among residents is a crucial component in disaster emergency response. Community-based aid distribution not only ensures targeted assistance but also fosters a spirit of mutual cooperation that strengthens long-term social resilience.

Flooding is one of the most recurrent natural disasters in Central Java Province, particularly during the rainy season. Diverse geographical characteristics, high rainfall intensity, and rapid urban development contribute to the region’s high vulnerability to flood hazards. According to the Central Java Statistics Agency, a total of 414 flood events and 407,784 affected victims were recorded between 2019 and 2021. This study aims to develop a web-based Geographic Information System (GIS) capable of mapping the spatial distribution and impact levels of floods across Central Java. The methodology includes collecting flood event data from the Central Java Statistics Agency, processing spatial data such as administrative boundary shapefiles, performing attribute integration between spatial and non-spatial datasets, and creating thematic maps using QGIS. The visualization outputs were exported into an interactive web format using the qgis2web plugin and subsequently integrated into a website developed with HTML, CSS, and JavaScript. The results show that the GIS system successfully visualizes flood-prone areas, identifies regions with high flood intensity, and enables users to explore detailed information through interactive digital maps. Additional website features—such as historical flood data, statistical summaries, and descriptive impact indicators—enhance the system's usefulness for disaster analysis. This study demonstrates the crucial role of GIS in supporting disaster mitigation, spatial planning, and policy evaluation related to flood management. Future research is recommended to incorporate more recent datasets and additional non-spatial variables such as rainfall intensity and floodwater depth to improve the system’s analytical accuracy and comprehensiveness.

Semarang Regency has considerable tourism potential with a variety of natural, cultural, and historical attractions. However, the region also faces a high level of disaster risk, particularly floods and landslides. This study aims to: (1) analyze the distribution of attractions, amenities, accessibility, and ancillary facilities as the basis for developing inclusive and sustainable tourism destinations; (2) identify areas with high tourism potential and disaster risk, particularly landslides, and formulate mitigation strategies to reduce the vulnerability of tourists and tourism industry actors; and (3) provide policy recommendations to local governments, tourism stakeholders, and the Regional Disaster Management Agency (BPBD) so that tourism development considers safety, sustainability, and integration with disaster mitigation systems. The method used is a mixed method, combining qualitative and quantitative approaches through spatial analysis with overlay, isochrone, and kernel density estimation (KDE) techniques to map the distribution of tourist attractions and disaster-prone areas. The results show that the integration of tourism and disaster data can provide insights into zoning priorities, evacuation routes, and the potential for developing disaster-safe tourism.

This article explores legal accountability for flood disasters occurring in several regions of Sumatra, which are widely alleged to result from large-scale logging activities. The analysis is conducted within the framework of the Indonesian legal system, with particular emphasis on contract law. This study adopts a literature-based research method by examining statutory provisions, legal doctrines, and relevant scholarly publications. The analysis demonstrates that flood events should not be understood solely as natural occurrences, but rather as ecological consequences arising from the failure to fulfill contractual obligations embedded in forest utilization permits. From a contract law perspective, forestry concessions establish binding legal relationships that impose environmental protection duties on permit holders in accordance with the principle of pacta sunt servanda. Logging activities that exceed authorized limits may therefore be classified as contractual default (wanprestasi) and, at the same time, constitute unlawful acts that cause harm to the state and affected communities. Accordingly, this study underscores the necessity of strengthening environmental protection clauses within concession agreements and applying strict liability principles to enhance legal responsibility and prevent recurring environmental harm.

This research extends the previous work of Tsaqila, Winiarti, and Widaningrum (2024), who applied the Complex Proportional Assessment (COPRAS) method within a decision support system for supermarket branch location selection. Unlike the prior study, which focused on Ponorogo through a web-based framework, this study expands the implementation of COPRAS to the Medan Area, Medan Kota, Medan Polonia, dan Medan Maimun districts, adapting it to local urban, social, and economic characteristics. The main objective is to identify the most strategic site for a new supermarket by analyzing multiple criteria, including land cost, population density, accessibility, safety, cleanliness, and disaster risk. Data were collected from both field surveys and official government publications. The findings reveal that the COPRAS method provides reliable and objective assessments among the evaluated alternatives, with Medan Area emerging as the most suitable location for supermarket development. Overall, this study broadens the practical scope of the COPRAS method in a different regional context and reinforces its reliability and adaptability as a multi-criteria decision-making tool in the modern retail industry.

This study is motivated by the high frequency and significant impacts of flooding in Indonesia, particularly the recurrent flooding of the Kali Lamong River in Gresik Regency, which causes substantial socio-economic losses each year. Although disaster management is normatively regulated by national policies, its effectiveness depends largely on collaborative governance among multiple actors. This study aims to analyze the practice of collaborative governance in flood mitigation in Gresik Regency using the model of Weber, Lovrich, and Gaffney (2005), which includes vertical, horizontal, and partnership dimensions, and to identify the key challenges that hinder its implementation. A descriptive qualitative approach was employed in flood-affected areas along the Kali Lamong River, involving BPBD, DPUTR, sub-district governments, village authorities, and local communities through interviews, observations, and document analysis. The findings reveal that collaboration has been established and functions relatively well, particularly in hierarchical coordination, division of roles among government agencies, strengthening of Destana, KENCANA, and SPAB programs, as well as CSR involvement and community participation all contributing to reduced flood duration. However, the implementation of collaborative governance remains constrained by slow land acquisition and infrastructure development, a predominantly reactive orientation, suboptimal early-warning systems between upstream and downstream areas, and uneven support from the private sector and academia. The study concludes that strengthening collaborative mechanisms and accelerating the resolution of structural barriers are essential to achieve more sustainable flood mitigation efforts in Gresik.

This study aims to analyze the impact of government expenditure development and government budgeting on the social assistance recipients affected by floods. The research approach uses a quantitative method with a total of 50 respondents selected through sampling techniques. Data processing was conducted using SPSS software with various statistical tests, including validity test, reliability test, multiple linear regression, t-test, and F-test. The results show that the development of government expenditure has a significant impact on the condition of the social assistance recipients. Additionally, government budgeting also has a significant impact on the effectiveness of social assistance distribution after the disaster. Simultaneously, both variables have a strong influence on the social assistance recipients, as reflected by the significant F-test value and the coefficient of determination (R Square) of 0.518. This means that 51.8% of the variation in the condition of social assistance recipients can be explained by the development of government expenditure and government budgeting. These findings highlight the importance of appropriate expenditure and budgeting policies to enhance the effectiveness of social assistance distribution, especially in disaster situations.
