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.

Generators are one of the important auxiliary aircraft needed on ships for power generation. During the operation of a diesel generator, continuous rotation occurs resulting in friction and erosion of the moving parts. The supporting factor for the smooth running of a diesel engine is a lubrication system that is supported by good lubricating oil quality, besides that it also needs to be supported by an adequate and good cooling system. The use of lubricants is one of the most important factors to ensure the performance of diesel engines. The lubricant is in charge of maintaining the condition of the engine so that it remains stable. This study aims to analyze the effect of using lubricating oil beyond the operating hours limit on engine heat. Furthermore, it also discusses steps to ensure diesel engine temperatures remain normal. This research was carried out during the practice of sailing on a ship for approximately one year. This study uses a descriptive quantitative research method. The primary data obtained directly utilizes observation methods, and documentation. Secondary data was obtained from existing articles and journals. The data analysis techniques used are descriptive analysis and inferential analysis. The results of this study show that the working hours of lubricating oil use have a significant influence on the increase in the temperature of diesel generator engines as evidenced by hypothesis tests on two engine units, namely AE1 and AE2. In the AE1 unit, a t-value of 18.467 with a significance of 0.000 was obtained, while in AE2 the t-value was 14.289 with a significance of 0.000. The significance value in both units is less than 0.05 so it can be concluded that the working hours of lubricated oil have a significant influence on the temperature of the genarato diesel engine on the ship.

Submarine pipelines are vital infrastructures in aviation fuel distribution, carrying high risks of operational disruption, safety issues, and environmental pollution.

Using a case study and descriptive-analytical approach based on the Continuous Improvement Program (CIP), the research analyzed quality, cost, delivery, safety, environmental, and workforce aspects. The results showed the method effectively drained aviation fuel without seawater contamination, prevented marine spills, maintained fuel quality within specifications, and completed repairs before critical stock levels were reached. Additionally, it provided significant cost savings compared to emergency supply operations and achieved zero safety incidents and environmental pollution. The integration of double-ended draining and oil bubble trap proved to be an effective, adaptive innovation with strong potential for replication and standardization in other aviation fuel submarine pipeline systems.

Floods are the most frequent hydrometeorological disasters in Indonesia and significantly contribute to increased trauma cases and disruption of healthcare services, particularly in vulnerable regions such as Aceh Province. These conditions are exacerbated by limited resources, damaged health facilities, and restricted access to referral centers. This study aims to examine the implementation of early emergency surgical management during flood disasters based on damage control surgery principles and international guidelines. A descriptive qualitative approach was employed through a literature review combined with field observations conducted during the emergency response phase of flood disasters in Bireuen Regency. Data were collected from direct clinical observations, brief interviews with healthcare providers, and documentation of trauma cases requiring early surgical intervention. The results indicate that effective patient stabilization can be achieved despite limited resources through airway, breathing, and circulation (ABC) management, hemorrhage control, wound irrigation, and fracture immobilization using simple and improvised equipment. Approximately 90% of patients were successfully stabilized prior to referral to definitive healthcare facilities. In conclusion, adaptive and timely application of damage control surgery principles plays a crucial role in saving lives and strengthening emergency surgical response during flood disasters.

This community service activity was carried out on 21 September 2024 at Banksasuci (Bank Sampah Sungai Cisadane), Cihuni, Gading Serpong, Tangerang Regency, as part of the SOUL PROJECT (Save Our Earth With Law) organized by the Student Executive Board of the Faculty of Law, UPN Veteran Jakarta. The program focused on urban planning and water management in relation to the impact of development on Cisadane River water quality. The Cisadane River is one of the most vital water sources in Banten Province, supplying raw water for PDAM, agriculture, fisheries, and industry. However, rapid urbanization—marked by dense residential sprawl and industrial expansion—has caused a significant and sustained decline in river water quality. Research shows that COD and BOD concentrations in the Cisadane River trended upward continuously from 2005 to 2012, driven by industrial effluents concentrated in Jatiuwung and domestic wastewater from slum settlements. Institutional management of the river remains fragmented across multiple agencies at city, provincial, and national levels with weak coordination. This activity engaged approximately 50 participants through legal education sessions, participatory field discussions, river cleaning, and tree-planting activities. Results indicate a significant increase in participant awareness of the link between spatial planning, infrastructure development, and river water quality. This program recommends integrated spatial governance and community-based monitoring as key strategies for protecting the Cisadane River ecosystem.

This study aimed to determine the effect of coffee husk waste application and shallot extract soaking on the growth of cat’s whiskers (Orthosiphon aristatus) cuttings. The research employed a factorial Randomized Block Design (RBD) consisting of two factors with 48 experimental plots. The first factor was the application of coffee husk waste, symbolized as “L,” with four treatment levels: L0 = 0 g/polybag (without coffee husk waste), L1 = 75 g/polybag, L2 = 150 g/polybag, and L3 = 225 g/polybag. The second factor was shallot extract soaking, symbolized as “B,” with four treatment levels: B0 = 0 ml/L of water, B1 = 5 ml/L of water, B2 = 10 ml/L of water, and B3 = 15 ml/L of water. Thus, there were 16 treatment combinations with three replications. The observed parameters included time to shoot emergence, number of shoots, plant height, number of leaves, leaf area, and survival percentage. The results showed that the application of coffee husk waste and shallot extract soaking had no significant effect on the growth of cat’s whiskers (Orthosiphon aristatus) cuttings across all observed parameters.

Heating, Ventilating, and Air Conditioning (HVAC) systems often suffer from significant energy wastage due to their inability to adapt to real-time environmental changes, leading to high operational costs. Although Proportional-Integral-Derivative (PID) controllers are widely used for their simplicity and reliability, they struggle to handle the complex dynamics of modern environments, requiring advanced optimization to enhance efficiency. This study aims to optimize PID controllers by integrating the Queen Honey Bee Migration (QHBM) algorithm to improve HVAC performance, energy efficiency, and adaptability. The research method employs an experimental approach that compares the performance of conventional PID controllers with PID controllers optimized using the QHBM algorithm under dynamic environmental conditions. The results show that the PID-QHBM system significantly outperforms the conventional PID system, achieving a rise time of 0.2649 seconds and a settling time of 1.6874 seconds with an almost negligible steady-state error of 9.4991e-08. Although it experiences a slight overshoot of 16.3810%, the system stabilizes quickly and maintains the target temperature efficiently. In contrast, the conventional PID controller exhibits slower response characteristics, with a rise time of 1.3730 seconds, a settling time of 2.5144 seconds, and a larger steady-state error of 0.0361. This study demonstrates that integrating the QHBM algorithm into PID controllers provides a more effective solution for real-time temperature control, offering substantial improvements in energy efficiency and system performance. The findings contribute to advancing intelligent HVAC control systems that can better adapt to environmental variations while minimizing operational costs.

Chronic Obstructive Pulmonary Disease is a chronic respiratory disease characterized by progressive and not fully reversible airflow limitation. Dyspnea is the primary symptom experienced by COPD patients and significantly affects their quality of life, especially among those hospitalized. This condition may lead to activity limitation, psychological distress, and decreased social functioning. This study aimed to determine the relationship between the level of dyspnea and the quality of life of COPD patients in the pulmonary inpatient ward of Cut Nyak Dhien General Hospital Meulaboh. This study employed an analytical design with a cross-sectional approach. The sample consisted of hospitalized COPD patients selected using purposive sampling. Dyspnea severity was measured using the Modified Medical Research Council (mMRC) scale, while quality of life was assessed using the St. George’s Respiratory Questionnaire (SGRQ). Data were analyzed using the Spearman correlation test to determine the relationship between variables.The results showed that most respondents experienced moderate to severe dyspnea and had poor quality of life. Statistical analysis revealed a significant relationship between dyspnea level and quality of life (p < 0.05) with a negative correlation.In conclusion, there is a significant relationship between dyspnea severity and quality of life in COPD patients, where higher dyspnea levels are associated with lower quality of life.

This study aims to evaluate the effectiveness of implementing an application-based water payment system as a strategy to reduce consumer arrears. Payment delinquency remains a significant challenge in the management of water utility services, often driven by low payment discipline, limited access to transaction channels, and the inefficiencies of conventional manual systems. Employing a quantitative approach, this research utilizes comparative data collected before and after the implementation of the digital payment application, supported by statistical analysis to measure changes in consumer payment compliance. The findings indicate that the adoption of an application-based payment system has a substantial positive impact on reducing arrears, as reflected in increased payment timeliness and a decline in the number of delinquent consumers. Features such as ease of access, automated notifications, and transparent billing information are proven to enhance consumer compliance behavior. These results underscore that the digitalization of payment systems can serve as an effective solution for improving operational efficiency and supporting the sustainability of water utility services.

Stock market volatility represents a key indicator of financial market uncertainty, particularly in emerging economies where market structures are still evolving and are highly sensitive to global shocks. This study aims to analyze and compare the volatility dynamics of stock markets in four Asian emerging economies: Indonesia, India, Malaysia, and Thailand. The research employs a quantitative approach using daily stock index data from January 2011 to January 2026 obtained from Yahoo Finance. Stock returns are calculated using logarithmic transformation and analyzed using the Generalized Autoregressive Conditional Heteroskedasticity (GARCH(1,1)) model. Prior to model estimation, stationarity and ARCH effect tests are conducted to ensure the validity of volatility modeling. The empirical findings indicate that all return series exhibit non-normal distribution, strong volatility clustering, and significant ARCH effects. The estimation results show that both ARCH and GARCH parameters are statistically significant, with persistence levels close to unity across all markets, implying that volatility shocks tend to persist over a long period. These findings suggest that emerging stock markets in Asia are highly sensitive to external shocks and exhibit long-memory volatility behavior. The results provide important implications for investors and policymakers in designing effective risk management and market stabilization strategies.

Civic Education holds a strategic position within the national education system as the primary instrument for shaping the personality of citizens in alignment with the values of Pancasila. This research is motivated by the phenomenon of moral degradation and the fading spirit of nationalism among the younger generation due to the unfiltered influence of globalization. The primary objective of this study is to analyze the extent of Civic Education's role in the school environment in transforming student character to possess noble morals, broad national insight, and a deep love for the motherland. The research method employed is a literature study with a qualitative approach, where data were collected through the analysis of various curriculum documents, scientific journals, and textbooks relevant to the implementation of the independent curriculum. Research findings indicate that Civic Education is not merely a theoretical transfer of civic knowledge but rather an effective process of value internalization through behavioral habituation within the school environment. The integration of teaching materials with practical applications in school life is proven to increase students' awareness of their rights and obligations as citizens. The analysis also reveals that strengthening moral character and national insight highly depends on teacher creativity in delivering interactive learning that is relevant to the students' social reality. The implications of this research emphasize the importance of revitalizing Civic Education teaching methods to be more adaptive to modern developments without losing national identity. Schools are expected to serve as laboratories of democracy and centers for sowing patriotic values to produce a golden generation that is not only intellectually competent but also possesses strong moral integrity to maintain the integrity of the Republic of Indonesia.

Indonesia ranks 36th among countries most prone to natural disasters, with 216 earthquakes recorded by BNPB between 2009 and 2019. Aceh is one of the high-risk regions, having experienced major disasters such as floods, earthquakes, and the 2004 tsunami. These conditions highlight the importance of knowledge of basic life support (BLS), which is essential for managing respiratory arrest, cardiac arrest, and airway obstruction in emergency situations. This study aimed to determine the level of basic life support knowledge among health workers at the North Lhoksukon Health Center, Aceh. A descriptive observational method with a survey approach was used to provide a general overview of respondents’ characteristics. The study applied univariate analysis and involved a total sample of 139 health workers. The results showed that most respondents had a good level of knowledge (116 people; 83.5%), followed by sufficient knowledge (13 people; 9.4%) and poor knowledge (10 people; 7.2%). These findings indicate that while the majority of health workers demonstrate good understanding, there is still a need for improvement among those in the sufficient and poor categories. Therefore, it is recommended that institutions provide regular BLS training to maintain and enhance the knowledge of health workers.

Bronchopneumonia is a type of infection of the lower respiratory tract that often occurs in children, especially toddlers. This disease is characterized by inflammation of the bronchioles and lung tissue which triggers increased production of secretions in the airways. The buildup of secretions often causes nursing problems in the form of ineffective airway clearance, which is indicated by ineffective coughing, rapid breathing, shortness of breath, and the appearance of additional breath sounds such as rales. Chest physiotherapy in children was carried out to evaluate the effectiveness of the clapping technique in helping to clear the airway in bronchopneumonia patients. The method applied in evidence-based practice (EBP) uses case studies with a nursing care approach. Intervention was given to three patients with a diagnosis of bronchopneumonia for three days, with a duration of approximately 1-2 minutes in each area of ​​the chest. Evaluation is carried out using a stethoscope and measuring time (clock), with the results recorded on an observation sheet. After chest physiotherapy (clapping), the three patients showed improvement in airway clearance, which was indicated by respiratory frequency returning to normal, no additional breath sounds (ronchi), and reduced secretion production. Based on these results, it can be concluded that the application of EBP through chest physiotherapy is effective in increasing airway clearance in bronchopneumonia patients.

Introduction: The incidence of ARI in children is estimated at 0.29 cases per child/year in developing countries and 0.05 cases per child/year in developed countries. There are 156 million cases of ISPA and most of them occur in India (43 million), China (21 million) and Pakistan (10 million) as well as Bangladesh, Indonesia and Nigeria with 6 million cases each. Of all ISPA cases that occur in the community, 7-13% are serious cases and require serious cases and require hospital treatment. Method: This research is a pre-experimental research with one group pre-post test design.Results: The results of the study showed that there was an effect of giving water vapor therapy and eucalyptus oil on reducing the frequency of ineffective airway clearance in children at RSIA Sitti Khadijah, Gorontalo City because it was found that the average frequency of coughing was 10.33 times per day before and after giving honey. Of 2.5 cc every day for 3 days, it was found that the average cough frequency decreased to 5.73 times per day so it can be seen that the difference between the cough frequency before and after was 4.6 times per day. Therefore, giving water vapor therapy and eucalyptus oil to children who are experiencing airway clearance is not effective in reducing the frequency of coughing.Conclusion: The conclusion of this study is that there is an effect of giving water vapor therapy and eucalyptus oil on ineffective airway clearance in children at RSIA Sitti Khadijah, Gorontalo City with a significant value of 0.000.
