This study aims to reflect on the theological meaning of natural disasters in Sumatra (Aceh, Simeulue, Padang) from an ecological perspective. Although Sumatra is geologically prone to earthquakes and tectonic activities due to its location on the Pacific Ring of Fire, hydrometeorological disasters such as floods and landslides are exacerbated by human actions, including deforestation, watershed degradation, and uncontrolled land conversion. This research employs a qualitative-descriptive approach using library research and a theological-reflective method. Primary sources include Sacred Scripture, Church documents (Laudato Si', Gaudium et Spes, General Directory for Catechesis), and relevant ecological theology literature. The findings indicate that natural disasters in Sumatra can be interpreted as "signs of the times" revealing both ecological and moral crises. Disasters are not divine punishment but consequences of humanity's misuse of freedom in managing creation. Ecological conversion is urgently needed at personal, social, and structural levels. Within the catechetical framework, disaster experiences become "texts of life" that guide the faithful toward mature faith expressed in lifestyle changes, solidarity, and responsibility for our common home.

An earthquake occurs when energy is suddenly released within the earth’s layers, potentially causing loss of life and environmental damage. One factor contributing to the high impact of earthquakes is the lack of student understanding and inadequate education on disaster preparedness. This study aimed to assess earthquake disaster management education at the Nur Adia Junior High School Education Foundation, Tanjung Selamat, Deli Serdang. A quantitative pre-experimental design with a one-group pretest and posttest was applied, involving 63 eighth-grade students. Data were collected through questionnaires to measure students’ knowledge before and after the educational intervention on earthquake disaster management. The results indicated that before the education, 69.8% of students rarely received information about earthquake causes, 61.9% had never participated in school earthquake evacuation simulations, and 55.5% had never practiced evacuation drills. After the educational intervention, knowledge improved, with 66.6% of students reporting that the program significantly increased their understanding of earthquakes. Statistical analysis showed a significant difference between pretest and posttest scores (Sig. 2-tailed = 0.000 < 0.05), confirming the effectiveness of the intervention. The study concluded that education on earthquake disaster management can enhance students’ knowledge and preparedness. It is recommended that schools implement regular educational programs and disaster simulation exercises to cultivate students’ readiness and promote a culture of disaster preparedness within the school environment.

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.

A research about study of sandstone slope stability using the Bishop Simplified method in Uu Samarinda has been conducted. This study was conducted to analyze the rebound number values of sandstone slopes, evaluate their stability level, and calculate the safety factor using the Bishop method. The results showed that the rebound number values were 22.34 at point 1, 19.83 at point 2, and 18.07 at point 3. The Uniaxial Compressive Strength (UCS) values at the observation points were 1.90 MPa, 1.62 MPa, and 2.21 MPa, respectively. Geological Strength Index (GSI) evaluation indicated a rating of 80–85, demonstrating intact/massive rock structure, fresh and unweathered rock surfaces, and very good rock quality. Based on the Bishop method analysis, the slope factor of safety in 6.525  with a probability of failure is 0.000%, indicating that the sandstone slope in Ulu Samarinda is highly stable even under external pressures such as heavy rainfall or minor earthquakes. This study provides crucial information on the mechanical characteristics and stability of sandstone slopes in ulu Samarinda, which can serve as a reference for technical planning, geotechnical risk mitigation, and the sustainable development of safe areas.

The Info BMKG application is a digital platform developed by the Meteorology, Climatology, and Geophysics Agency (BMKG) to provide information on weather, earthquakes, air quality, and early disaster warnings. This application is expected to enhance public preparedness in facing potential natural disasters. However, in its implementation, the Info BMKG application still encounters several issues, one of which is delays in delivering weather and disaster information. This study aims to analyze the effectiveness of the Info BMKG application in providing weather and disaster information. The research applies Budiani's (2007) theory, using four indicators: Program Target Accuracy, Program Socialization, Program Objectives, and Program Monitoring. This study employs a qualitative descriptive method with data collection through interviews, observations, and documentation. The findings indicate that the Info BMKG application has made a significant contribution to supporting public preparedness for disasters. While the application is relatively effective in providing weather and disaster information in North Jakarta, further development is still needed. Improvements in information accuracy, notification speed, and enhanced public socialization will help improve the quality of the application’s services in the future.

Gorontalo Province is an area with a high level of disaster vulnerability, both from hydrometeorological disasters such as floods and landslides, as well as geological disasters such as earthquakes. This condition requires an integrated, modern, and sustainable disaster training facility. Unfortunately, until now Gorontalo does not have a representative disaster management education and training center to support community preparedness. This research aims to design a Disaster Management Education and Training Center that not only functions as an education and simulation place, but also integrates green architecture principles to create an environmentally friendly and energy-efficient learning environment. The method used is qualitative descriptive with primary data collection through observation, interviews with stakeholders, and field documentation. Secondary data were obtained from literature studies, disaster architectural precedents, and spatial planning regulatory studies. The design site was chosen in Limboto District with considerations of accessibility, development potential, and geographical conditions. Analysis is carried out on spatial, functional, and climatological aspects to produce an optimal zoning concept and the orientation of building masses according to the tropical climate. The design results show that an area of 19,371 m² can accommodate all space needs with the utilization of KDB of 25.4%. The application of green architecture is realized through the use of environmentally friendly local materials, natural lighting, cross ventilation, solar panels, and rainwater management systems. The simulation facilities for floods, landslides, earthquakes, and fires are designed based on experiential learning so that participants can experience disaster scenarios firsthand. This design is expected to be a model of sustainable tropical disaster architecture, replicate in other disaster-prone areas, and encourage the creation of a disaster-aware culture. This research also opens up further research opportunities related to energy performance evaluation and the application of digital technology in disaster education.

This comprehensive study examines the disaster management strategies of Japan and the Philippines, focusing on their responses to earthquakes through the lens of Systems Theory. Japan's centralised model emphasises hierarchical coordination, advanced technological integration, and pre-disaster planning, ensuring rapid and efficient responses. Conversely, the Philippines employs a decentralised framework, leveraging community-based initiatives and localised decision-making, though often constrained by resource disparities. Through rigorous data collection, including field observations, stakeholder interviews, and policy analysis, this research provides a comparative analysis highlighting both systems' strengths and limitations. The findings reveal that Japan's technological infrastructure and institutional coordination excel in early warning and response efficiency, while the Philippines' grassroots participation fosters community resilience despite resource constraints. This study proposes a hybrid approach that integrates centralised coordination with community-driven participation to enhance disaster resilience in earthquake-prone nations, offering transferable lessons for public administration systems worldwide.

West Sumatra, situated at the convergence of the Indo-Australian and Eurasian tectonic plates, experiences frequent earthquakes and aftershocks due to the complex geological setting. This study utilizes the Omori-Utsu method, a modified version of Omori’s law by seismologist Tokiji Utsu, to estimate aftershock duration. Data on aftershocks from significant earthquakes (magnitude ≥5.5M) between 2021 and 2023 were accessed through the BMKG earthquake catalog. The study finds that aftershock durations vary significantly depending on the earthquake's tectonic origin. The longest recorded aftershock duration occurred after the West Pasaman earthquake on February 22, 2022, lasting 21 days, while the shortest was one day following the Mentawai earthquake on September 11, 2022. These variations highlight the influence of tectonic structures on aftershock activity, with subduction zones exhibiting shorter decay times. This research provides critical insights into earthquake behavior, aiding in disaster preparedness and mitigation strategies for the West Sumatra region.    

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.

This research aims to see the results of activities to increase employee capacity through the disaster safe hospital (RSAB) program at Kilisuci Regional Hospital, Kediri City. Hospital preparedness plans are very important in ensuring the safety of the hospital environment and the actions that need to be taken to ensure health services remain available during a disaster situation. Kilisuci Regional Hospital does not yet have a preparedness plan that is documented, tested, and involves the surrounding community to be ready to face disasters. The methods used in this community empowerment activity include pretest-posttest, lecture-discussion, direct training/practice, observation and evaluation methods. The research results show that Disaster Management at the Kilisuci Regional Hospital is very necessary considering that Kediri City has a variety of potential disasters and is in an area that has potential threats from floods, fires, the Covid-19 pandemic, Mount Kelud eruptions, traffic accidents and earthquakes. There was an increase in pretest and posttest results of 14.60 points. It is felt that activities to strengthen employee capacity through the Hospital Disaster Plan (HDP) program need to be developed further because hospitals need more preparedness capacity in facing disasters or emergency situations and can support during hospital accreditation.

An earthquake is a type of natural disaster which occurs due to the movement of tectonic plates. The time and location of an earthquake cannot be predicted, so people living in earthquake-prone areas should have good knowledge of earthquake disasters as capital in anticipating earthquake disasters. Various efforts need to be made to increase knowledge about earthquake disasters, one of which is through education. In the education sector, efforts to increase knowledge about earthquake disasters can be done through the integration of game-based learning in schools. One of the schools that is vulnerable to earthquakes is SMP Negeri 1 Polanharjo, Klaten Regency. This school is one of the schools that was affected by the earthquake disaster in Klaten Regency in 2006. The aim of this activity is to (1) increase knowledge about earthquake disasters through the implementation of game-based learning media (disaster SOS and puzzles) for social studies teachers and students at SMP Negeri 1 Polanharjo and (2) increase the capacity of teachers and students in dealing with earthquake disasters. The targets of this activity are social studies teachers and OSIS administrators at SMP Negeri 1 Polanharjo. The implementation method is through socialization and practice in using game-based learning media, namely disaster SOS and puzzles. The results of the activity showed that (1) the implementation of game-based learning media (disaster SOS and puzzles) can increase the motivation of teachers and students in studying earthquake disasters and (2) this media can increase the capacity of teachers and students regarding earthquake disasters.

Doomsday is the culminating event of all life on this earth in the form of the destruction of the universe and all its contents, including human existence. No creature can survive the apocalypse. This phenomenon is explained in several verses of the Koran. Imam Al-Qurt}ubi is of the view that the last day and doomsday will occur if knowledge is revoked, there will be many earthquakes, time will pass very quickly, there will be a lot of slander and chaos and murder will occur everywhere. The aim of this research is to determine the linguistic aspects of the doomsday phenomenon in al-Qurtubi's view. The research method used in this research is library research. The data source was obtained from primary data sources in the form of the Al-Qurt}ubi interpretation book entitled Al-Jamī' Li Al-Ahkam Al-Qur'ān. And primary data sources come from various related literature in the form of books and journals. Data collection techniques use library and documentation techniques. Then the data was analyzed using content analysis. This research resulted in the finding that the linguistic aspects regarding the doomsday phenomenon are known to be dominated by metaphors in the narrow and open sense in several verses of the Qur'an. These two forms of language style both do not mention comparative motifs.

A slope is an area of ​​morphology that has a certain geometry, namely the highest and lowest parts and has the potential for landslides if it is in an unstable condition (Wesley & Pranyoto, 2010 in Khodijah, et al, 2022). A slope can be composed of soil, rock, or both. Slope stability is influenced by slope geometry, physical and mechanical characteristics of the slope-forming material, water (hydrology and hydrogeology), rock weak plane structure (location, direction, frequency, mechanical characteristics), natural stresses in the rock mass, local stress concentrations, vibrations ( natural: earthquakes; and human actions: effects of blasting, effects of heavy equipment passing by), climate, the results of mine workers' actions, and thermic effects (Moshab, 1997 in Arif, 2016).

The internal force in the sample column obtained the same results in story 1 column C1 and C2 of 59.57 kN at Fx, Fy of 4.72 kN and moment of 5.01 kN-m, through a combination (static + seismic). The value of the sample beam on the 3rd floor has the highest value on B1, the Fx value was 4.73x10-14 kN, Fy was 9.09 kN, and the moment was 13.88 kN-m.

Java Island is the most disaster-prone region in Indonesia because Java Island is located in a convex zone (meeting each other) between two tectonic plates, namely the Eurasian Plate in the north, and the Indo-Australian Plate which causes the formation of volcanoes and earthquakes. Java Island which is near the convergence zone of these plates causes Java to become a disaster-prone zone, with many volcanoes that often erupt and experience many earthquakes. Volcanoes are formed due to the movement of hot magma from the meeting of plates to the earth's surface. While earthquakes occur due to the instantaneous movement of earth plates.
