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.

Indonesia is a developing country located at the convergence of four tectonic plates, making it highly prone to natural disasters such as earthquakes, tsunamis, landslides, and volcanic eruptions. These frequent disasters highlight the critical need for reliable electricity during emergencies. However, disaster-affected areas often struggle to restore power due to accessibility issues. To address this, alternative energy sources are needed, and Solar Power Plants (PLTS) offer a practical solution. PLTS are easy to implement, depend only on sunlight, and provide clean energy with low carbon emissions. Under clear skies, solar radiation can reach 1,000 Watts per square meter, making it a powerful energy source. Additionally, PLTS systems are adaptable and can be deployed in various formats, including mobile units. This study focuses on designing a Mobile PLTS to support BASARNAS operations in disaster zones. Data collection was conducted using resources from BNPB, BMKG, BASARNAS, and NASA. The analysis includes the geographical characteristics of the site, solar radiation intensity, and the operational dimensions of the BASARNAS Mobile Truck. The study aims to determine the suitable system specifications and estimate the energy production capacity of the Mobile PLTS. The proposed design features 20 solar panels, each with a capacity of 300 Wp, producing an average of 27.70 kWh per day. It also includes 16 batteries for energy storage. The remaining space in the truck can be used for transporting logistics or essential tools, making it a multifunctional unit ideal for disaster response scenarios.

Flood disaster is the most frequent disaster in Indonesia. Based on BNPB records throughout 2021, flood disasters have occurred 1,279 times. Poor drainage system can be one of the factors causing flood disasters. Way Mhorock Village, Abepura District is one of the areas that has poor drainage network quality. This is because Way Mhorock Village is one of the centers of community activities, so it has the potential to cause flooding. This study examines the quality of the drainage system against disasters in Abepura District by focusing on Way Mhorock Village. The research methods used to achieve the objectives in this research are qualitative methods, spatial analysis, and analytical hierarchy process. Qualitative descriptive analysis method to assist and describe the actual drainage problems in the field in the form of pictures. Spatial analysis method using GPS by recording problematic drainage points then processed using ArcGIS software. Analytical Hierarchy Process method by capture the perspective of stakeholders from the agency to determine the assessment of the quality level of the drainage system that has the potential to cause flooding in Way Mhorock Village. The results showed that there are 4 problems that affect the quality of drainage in Way Mhorock Village, namely drainage sedimentation, land use change, drainage cross section, and the volume of waste found at 33 points in Way Mhorock Village. Based on the results of the analytical hierarchy process using an expert choice application, drainage sedimentation is the most influential criterion on improving drainage quality with alternative handling provided in the form of law enforcement policies against environmental violations by the community.  

Drought is an event in an area that experiences water scarcity at a certain time which is caused by a certain event. According to BNPB (2023), Central Java Province ranks first in drought disasters with 24 areas in Central Java experiencing drought disasters. According to BPBD, Sukoharjo Regency is one of the areas experiencing drought, one of which is Weru District, Tawang Village. The impact of the drought disaster has resulted in problems in the economic, social health and education sectors. One of the impacts of the drought disaster in the health sector is a decrease in the level of personal hygiene in teenagers during menstruation. The aim of this research was to determine the level of personal hygiene during menstruation among adolescents in drought areas in Tawang Village, Sukoharjo Regency. This research method uses a quantitative descriptive method with a sample size of 73 respondents and uses random sampling techniques. The results of the research showed that the personal hygiene level of the majority of respondents was moderate, as many as 40 respondents (54.8%). The conclusion is that the level of personal hygiene during menstruation in teenagers in drought areas is in the moderate category.

Bioterrorism is an intentional act of terror by making pathogenic germs or toxins with the aim of killing or causing harm to individuals or populations (humans, animals and plants) which results in political, economic, social and cultural conditions. Law Number 4 of 1984 concerning Outbreaks of Infectious Diseases, until the arrival of the Covid 19 pandemic and the emergence of a lawsuit against the Law to the Constitutional Court. Not in accordance with the development of the Law on Infectious Disease Outbreaks that is no longer relevant to various current conditions. Revision of the Law on Combating Outbreaks of Infectious Diseases is an unavoidable necessity at this time. Revision of the Plague Law should be the task and responsibility of the DPR. The Central Government through the Task Force for the Acceleration of Handling COVID-19 has made four strategies that will be consistently implemented to strengthen the physical distancing policy as a basic strategy to overcome the Corona COVID-19 Virus pandemic.
