Limited land availability is a major constraint in developing school infrastructure in active urban educational facilities. This study evaluates the classroom development plan at SDN 39 Lubuklinggau from the perspective of a planner, focusing on land limitation, functional needs, safety, constructability, and long-term building performance. A descriptive-evaluative approach was applied through technical observation, document review, alternative assessment, weighted scoring, and risk analysis. The results indicate that horizontal expansion is constrained by limited open space and may reduce internal circulation, student activity areas, and emergency space. Three alternatives were compared: horizontal expansion, building rearrangement, and a two-storey classroom scheme. The two-storey alternative obtained the highest score of 84, compared with 61 for rearrangement and 56 for horizontal expansion. However, its feasibility depends on further soil investigation, structural design, staircase and evacuation safety, utility coordination, construction phasing, and strict site safety control. The study recommends that the planner prioritize detailed site measurement, geotechnical investigation, detailed engineering design, construction safety planning, and post-construction functional evaluation. A vertical classroom strategy can be considered a rational solution for land-constrained schools when supported by accountable technical planning and integrated project control.

Evacuation planning in spatial networks requires the identification of critical nodes that maintain connectivity, accessibility, and flow distribution during emergency situations. Existing approaches often rely on individual centrality measures, which capture only a single structural dimension of node importance and may therefore produce incomplete or biased prioritization. To address this limitation, this study proposes a Composite Centrality Framework for identifying critical nodes in meso-scale spatial networks with semi-structured connectivity. The network is modeled as a weighted undirected graph, and Degree, Betweenness, and Closeness Centrality are integrated into a unified composite index to capture complementary structural roles. The framework is implemented in MATLAB and evaluated using a real-world campus spatial network consisting of 30 nodes and a synthetic network comprising 16 nodes with comparable structural characteristics. The results reveal a highly uneven distribution of node importance, with a small set of structurally dominant nodes consistently identified across both networks. In the campus network, node P1 achieves the highest composite centrality score (0.2195) and ranks first across the individual centrality measures, indicating its dominant role in maintaining network connectivity, accessibility, and flow distribution. Quantitative evaluation demonstrates strong agreement between the composite ranking and the individual measures, with Spearman rank correlation coefficients of 0.94, 0.89, and 0.91 for Degree, Betweenness, and Closeness Centrality, respectively. However, only one node (P1) appears simultaneously in the top five of all rankings, highlighting the complementary nature of the individual centrality measures and supporting the need for multi-criteria integration. Sensitivity analysis across three weighting scenarios yields rank correlations exceeding 0.97, confirming ranking stability and methodological robustness. Overall, the proposed framework provides a balanced and reliable approach for identifying critical nodes and demonstrates potential applicability to evacuation planning and spatial network analysis in semi-structured environments.

This study aims to analyze the role of the Regional Disaster Management Agency (BPBD) of East Flores Regency in managing the eruption disaster of Mount Lewotobi Laki-Laki during the pre-disaster, emergency response, and post-disaster phases. The study employed a descriptive qualitative method involving 18 informants from BPBD and affected communities in Wulanggitang and Ile Bura Sub-districts. Data were collected through observation, interviews, and documentation. The findings show that during the pre-disaster phase, BPBD implemented preparedness measures through disaster-prone area mapping, the establishment of Disaster Preparedness Teams and Disaster-Resilient Villages, public outreach, and the use of local wisdom. However, outdated contingency plans, limited early warning systems, weak relocation efforts, and low public awareness contributed to panic and casualties during the eruption. In the emergency response phase, BPBD successfully coordinated evacuation efforts, established emergency posts, and distributed logistics effectively. Nevertheless, displaced communities experienced discomfort due to prolonged emergency conditions and limited fulfillment of basic needs in temporary shelters. In the post-disaster phase, BPBD conducted rehabilitation and reconstruction through transportation recovery, trauma healing programs, and permanent housing development based on the Rehabilitation and Reconstruction Plan (R3P). However, limited funding and delays in reconstruction processes remained major challenges. Therefore, improving coordination, institutional capacity, disaster communication, and community participation is essential for effective disaster management.

The results showed an increase in students’ and school members’ knowledge and preparedness in facing disasters. Participants were able to understand evacuation routes, perform self-protection actions, and follow evacuation procedures in an orderly and rapid manner. Evaluation results indicated that disaster mitigation understanding reached 85%, self-rescue ability 88%, accuracy in following evacuation routes 90%, discipline during simulation 92%, and participant involvement reached 95%. This activity also encouraged the formation of a disaster awareness culture and the emergence of active student roles as preparedness pioneers within the school environment. Therefore, disaster simulation proved to be an effective educational medium in improving the capacity and preparedness of school communities toward earthquake and tsunami risks.

Air transportation plays an important role in supporting mobility, tourism, and emergency activities such as medical evacuation and search and rescue (SAR). One of the essential supporting facilities for helicopter operations is a heliport, which must meet safety standards, including an adequate lighting system. This study aims to design an LED floodlight installation system for the Main Helipad of Fly Bali Heliport based on the international standard ICAO Annex 14 Volume II, while considering the corrosive coastal environmental conditions. The research method used is an engineering design approach with quantitative analysis of illumination requirements and current carrying capacity (CCC). Data were obtained through literature studies based on ICAO, FAA, and CAP 437 standards, as well as field observations. The design process includes determining the number and placement of floodlights, technical specifications, and electrical installation systems, including cable and protection selection. The results show that the configuration of four LED floodlight units is capable of producing a minimum illumination of 10 lux evenly across the TLOF and FATO areas in accordance with ICAO standards without causing glare. The use of Avlite AV-HL-FL floodlights with IP66 protection is suitable for coastal environments. The electrical installation system using NYY 2×2.5 mm² cables and a 2 Ampere MCB ensures system safety and reliability. Therefore, this design can enhance heliport operational safety and support optimal night operations.

This study aims to analyze the technical and economic impact of power evacuation work on the 20 kV distribution system at PT PLN (Persero) UP3 East Bali. The main problem studied is the high losses and poor voltage profile on the downstream side of the Kintamani feeder. The method used is load flow simulation using ETAP software with a comparative approach to conditions before and after power evacuation. The results showed that the active losses decreased from 1.017 MW to 0.626 MW (efficiency 38.45%), accompanied by an increase in the end voltage from 16.32 kV to 18.72 kV and 19.38 kV, thus meeting the SPLN 1:1995 standard. The reduction in losses resulted in energy savings of 3,425,160 kWh/year. From the economic side, a payback period (PBP) of 1.40 years was obtained, which shows that the project is financially feasible. In addition, the improvement of network performance also contributes to the reliability of the distribution system and the continuity of the distribution of electrical energy to customers. Thus, power evacuation work has been proven to be effective in improving power distribution efficiency, improving voltage quality, and providing significant economic benefits.

Occupational Health and Safety (OHS) is a crucial aspect in manufacturing industries due to the high risk of workplace accidents caused by heavy machinery, chemical substances, and intensive production activities. Companies usually provide Standard Operating Procedures (SOP) as safety guidelines; however, SOPs are often delivered in long textual formats that are less engaging, making workers reluctant to read or difficult to understand quickly. This study aims to design an infographic-based SOP media as an effective visual communication tool to improve workers’ understanding of safety procedures. The research applies a qualitative method with a design approach through workplace observation, interviews with HSE personnel, literature review, and design validation using questionnaires. The results produce infographic media in the form of posters and signage presenting PPE usage procedures, hazard warnings, and evacuation steps using safety color codes, icons, and readable typography. The conclusion indicates that infographic SOP media is more effective than text-based SOP because it improves readability, comprehension, and workers’ memory of safety procedures.

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.

Aceh Tamiang Regency is one of the regions in Aceh Province that is highly vulnerable to annual flooding due to river overflow and high rainfall intensity. Flood disasters often cause significant material and non-material losses, which are exacerbated by the limited public understanding of flood mitigation, early warning signs, and appropriate self-rescue procedures. This community service activity aims to increase public awareness, knowledge, and preparedness in facing flood threats through disaster mitigation socialization programs. The method applied in this activity includes participatory socialization, interactive discussions, and simulations of emergency response actions involving local communities, village officials, and volunteers. The program emphasizes recognizing early signs of flooding, understanding emergency evacuation routes, and improving coordination during disaster response. The results indicate a significant improvement in community knowledge regarding flood risks, early warning indicators, and emergency measures that should be taken before and during flooding events. Furthermore, the activity successfully strengthened coordination between village authorities and local volunteers in managing emergency response posts and distributing aid effectively. Through this socialization program, the community of Aceh Tamiang is expected to develop greater disaster resilience and preparedness. Increased awareness and coordinated response mechanisms are anticipated to minimize the adverse impacts of future flooding events, thereby reducing potential losses and enhancing community safety.

Indonesia, as a country with a high level of disaster vulnerability, faces an increased risk of communicable diseases during the emergency response phase due to disrupted sanitation, limited access to clean water, overcrowded evacuation shelters, and weakened health services. This study aims to analyze the strategic role of health workers in health education and the prevention of communicable diseases during disaster emergency response. The method used is a literature review of relevant national and international scientific articles. The findings indicate that health workers have a multidimensional role, not only as providers of curative services but also as educators, change agents, advocates, and collaborators in promotive and preventive efforts. Effective health education, participatory risk communication, strengthened epidemiological surveillance, and the implementation of Infection Prevention and Control (IPC) are key strategies to reduce the risk of communicable disease outbreaks. However, implementation in the field still faces challenges, including limited resources, cross-sectoral coordination constraints, heavy workloads, and suboptimal disaster-related policy systems and standard operating procedures (SOPs). Therefore, strengthening the capacity of health workers through training, policy support, and community-based approaches is necessary to enhance health system resilience in responding to disaster crises.

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 purpose of this study is to investigate the strategic role of air transportation management in Military Operations Other Than War (MOOTW), particularly in archipelagic contexts such as Indonesia, where rapid humanitarian response, territorial surveillance, and civil–military cooperation are essential for resilience. By applying a Systematic Literature Review (SLR), this article synthesizes findings on humanitarian logistics, technological transformation, and policy frameworks for strengthening national defense readiness. Design/methodology/approach – This study employs a qualitative Systematic Literature Review (SLR) methodology guided by PRISMA principles, analyzing 30 scholarly contributions from 2009–2025, including international peer-reviewed journals, Routledge and Springer volumes, arXiv preprints, and Indonesian academic publications.Results highlight that strategic air  transportation is indispensable for disaster relief, medical evacuation, and supply delivery in archipelagic nations. The adoption of AI, machine learning, UAVs, and reinforcement learning has enhanced responsiveness and equity in humanitarian supply chains. However, persistent challenges include aging fleets, interoperability constraints, and fragmented civil–military coordination. The study underscores the need for modernization of air assets, institutionalized civil–military collaboration, and integration of AI-based routing and command systems. Strengthening these aspects can enhance Indonesia’s resilience and preparedness in MOOTW scenarios. This article uniquely bridges global research on data-driven air power with Indonesian defense perspectives, proposing a scalable strategic framework for air transportation management that advances archipelagic resilience.

This research analyzes the implementation of Occupational Safety and Health (K3/OSH) in the automation project of the Vacuum Pan machine at a sugar factory in Indonesia. The Vacuum Pan machine automation project poses high potential hazards due to its involvement with electrical systems, high-pressure pipes, and the installation of electrical and automatic control systems. The research methods used were daily direct observation in the field and interviews with the factory's safety (EHS) personnel, project workers, and interns for one month, from July 7 to August 8, 2025. The results show that K3 planning, such as the availability of HIRADC documents, SOPs, Safety Plans, and K3 facilities (APAR, evacuation routes, safety signs), has been well-implemented and adheres to applicable standards. K3 supervision activities include Safety Inspection (routine twice a week), Safety Patrol (daily and spontaneous), and Safety Talk or Toolbox Meeting (routine every Wednesday). However, the aspect requiring improvement is worker discipline, particularly in the use of Personal Protective Equipment (PPE) and adherence to Standard Operating Procedures (SOPs), which were recorded at compliance frequencies of 65% and 60%, respectively. Workers' response to hazardous situations was also found to be less responsive (50%). In conclusion, while K3 planning and facilities are adequate, the overall K3 implementation needs to be optimized through increased supervision and the establishment of a disciplined culture regarding PPE and SOPs.

This research aims to identify potential hazards and assess the level of fire risk in a textile company located in Sukoharjo Regency using the Hazard Identification, Risk Assessment, and Risk Control (HIRARC) method. The research background is based on the high fire hazard potential in the textile industry due to the use of flammable chemicals, high operating temperatures, and the accumulation of combustible fibers and textile dust. A descriptive research approach was applied through field observations, interviews with workers and the OHS team, and technical document analysis. The results showed that the highest risk levels were found in the dyeing process, electrical panel room, and machine maintenance activities (welding/repair), with risk scores reaching 20 (high category). The main contributing factors included non-standard electrical installations, poor ventilation, and unsafe work behavior. Risk control strategies are recommended through technical, administrative, and behavioral approaches, including smoke detection systems, routine evacuation training, and the reinforcement of safety culture. The implementation of these measures is expected to improve the effectiveness of occupational health and safety management systems and reduce the potential for fire incidents in the textile industry.

Colitis is an inflammatory characterized by thickening of the mucosal wall of the colon. The Colon In Loop examination is one of the diagnostic procedures for colitis, utilizing contrast media to assess the functional condition of the colon. At the Radiology Installation of RSUD (Regional General Hospital) Banyumas, the radiological procedure for Colon In Loop was performed on post-colostomy patients, thus differs from previous studies. This study aims to identify the examination procedure of Colon In Loop at RSUD Banyumas, the rationale for using Anteroposterior (AP) and Lateral projections, and the reason for not performing evacuation before the administration of negative contrast media. This qualitative descriptive study employed a case. The subjects included three radiographers, one radiology nurse, and one radiology specialist. The object of study was the Colon In Loop Post Colostomy examination procedure in colitis cases. Data were collected through observation, interviews, documentation. Data analysis involved data reduction and data presentation. confirmed with theory, and narrative presentation leading to conclusions. Result shows contrast media consisting of 250 grams of barium sulfate dissolved in 1000 ml of water (25% w/v). The examination is performed in stages followed by AP and Lateral projection imaging to evaluate contrast distribution in the colon. Negative contrast media administration is performed without prior evacuation to enhance patient comfort and reduce examination time. When administering negative contrast media, evacuation is not performed before air is introduced. This is done based on the patient's condition, to shorten the examination time, and due to considerations regarding the quality of barium sulfate; thus, evacuation could impair barium adherence to the colon mucosa. In conclusion, AP and lateral projections are considered adequate for establishing a diagnosis of colitis. The omission of evacuation is based on patient condition, time efficiency, and the suboptimal quality of barium. It is recommended to perform evacuation and increase barium concentration to improve adherence to the colon mucosal wall.

Kaloran Village is an area characterized by steep slope topography that makes it vulnerable to landslides, especially during the rainy season with high rainfall intensity. Although the landslide risk level in this village is still relatively low and has never caused any casualties, the potential for material losses and psychosocial impacts that may arise still need to be seriously anticipated. Disaster risk reduction efforts in Kaloran Village are carried out through the Disaster Resilient Village Work Program (Destana), which aims to increase the capacity and capability of the community in facing disaster threats. The program implementation method consists of three main stages: preparation through focus group discussions (FGDs) and interviews with stakeholders, preparation of the Destana document containing mitigation strategies and steps, and community empowerment through socialization activities and preparedness training. The results of the study indicate that Kaloran Village is categorized as a Medium Resilient Village with a resilience score of 68.97. This achievement serves as an important basis for strengthening the village preparedness system, which is followed up with the establishment of the Disaster Risk Reduction Forum (FPRB) "Kaloran Tangguh Rescue" as a community coordination forum. In addition, evacuation route maps were produced, which serve as technical guidance in the event of a disaster, and the development of the Destana (Disaster Preparedness and Disaster Management) and Contingency Plan (Renkon) documents, which serve as official guidelines for disaster mitigation and management efforts at the village level. This program demonstrates that active community participation, collaboration between stakeholders, and the development of strategic documents can strengthen village preparedness for the threat of landslides.

This study examines disaster mitigation efforts in minimizing disaster risk in Manado City and identifies the key challenges as well as the strategies implemented by the Regional Disaster Management Agency (BPBD: Badan Penanggulangan Bencana Daerah). Employing a qualitative descriptive approach, data were collected through interviews, direct observations, and document analysis, with the Head of BPBD serving as the primary informant. The analysis was conducted using Miles et al.’s (2014) interactive model, which consists of data condensation, data display, and conclusion drawing, thereby ensuring systematic interpretation of findings.The results indicate that disaster mitigation efforts in Manado consist of both passive and active strategies. Passive measures include strengthening institutional frameworks, enhancing governance capacity, integrating disaster management planning into regional development programs, and advancing education and research to support long-term disaster risk reduction. In contrast, active mitigation emphasizes community-based actions, such as the installation of disaster warning signs, the provision of basic disaster training for officials and volunteers, the establishment of temporary evacuation shelters, and the implementation of both structural interventions (e.g., drainage construction, flood control) and non-structural measures (e.g., socialization, counseling, and public campaigns). Despite these initiatives, several challenges persist. Limited public awareness, inadequate infrastructure and facilities, a shortage of skilled human resources, weak planning and socialization, complex disaster causes, and environmental vulnerabilities all reduce the overall effectiveness of disaster risk reduction efforts. To address these obstacles, BPBD Manado fosters collaboration with various stakeholders, including government institutions, academia, non-governmental organizations, and local community groups. Moreover, the agency emphasizes the use of disaster risk assessments and hazard mapping as evidence-based foundations for policy formulation and implementation.

This research was conducted from June to July 2025 in Binjai City, with the primary focus being analyzing the readiness of the Binjai City Regional Disaster Management Agency (BPBD) to implement a flood early warning system utilizing artificial intelligence (AI). The data collection process was conducted through a literature review, which involved reviewing various theories and previous research results regarding the application of AI and Internet of Things (IoT) technology in the context of disaster mitigation. Based on the results of the study, it was found that the use of technologies such as ultrasonic sensors, microcontrollers, fuzzy logic, and automatic notification systems can provide real-time warnings with a high level of accuracy and a fast response. This system enables early detection of rising river levels through automatic measurements, intelligent data processing, and sending notifications to authorities and affected communities within seconds. By integrating historical data and machine learning-based predictions, this system is also able to depict potential flooding before it occurs, providing a longer response time for evacuation. However, the readiness of the Binjai City BPBD still faces various challenges, such as limited digital infrastructure, the need for human resource training in the technology field, and inadequate budget allocation. Therefore, cross-sector collaboration and ongoing policy support are needed for optimal implementation of this system. The use of AI and IoT in early warning systems is not only technically relevant but also urgent in the face of increasing climate change and flood risks. A strategy involving cross-sector collaboration between government, academia, and the private sector is needed to develop an adaptive and sustainable early warning system.

A landslide disaster is a life-threatening event that can result in loss of life, environmental damage, and property loss, so it is necessary to have self-evacuation capabilities. Self-evacuation capabilities can be improved with the DEMASI method (Video Animation and Simulation). The aim of this research is to determine the effect of DEMASI (Video Animation and Simulation) on the ability to self-evacuate landslides in class X students at SMA Negeri 1 Dongko. Pre-experimental design research design with a one-group pretest-posttest approach without control. The purposive sampling technique obtained 34 respondents from 170 populations. The research instrument used an observation sheet on self-evacuation capabilities for landslide disasters. Wilcoxon Signed Rank Test statistical test with α 0.05. The results of the research before being given DEMASI intervention (Video Animation and Simulation) were that all (100%) respondents had poor abilities, and after the intervention almost all (85.3%) respondents had good abilities. Results: The statistical analysis showed that the p-value was 0.000 < α 0.05, so there was an influence of DEMASI (Video Animation and Simulation) on students' self-evacuation ability for landslide disasters. The DEMASI method (Video Animation and Simulation) combines two methods that are more interesting, effective, and interactive because audiovisuals recorded by optic and auditory nerves are sent to the occipital lobe and temporal lobe to be described and processed, which involves many brain regions and the frontal lobe so that they can influence the respondent's abilities. The DEMASI method can be used as an educational medium for students and other school residents in an effort to improve their ability to self-evacuate in landslide disasters.
