Maritime safety is a critical aspect of military ship operations, where mastery of Ship Salvage Equipment (PEK) becomes a fundamental competency for cadets of the Indonesian Naval Academy (AAL). This research aims to identify and analyze the benefits of knowledge of Ship Salvage Equipment (PEK) for AAL cadets in the context of professional competence development, operational readiness, and leadership character formation. Using a mixed methods approach with a sequential explanatory design, this study involved 312 AAL cadet respondents from three batches (2022-2024) selected through stratified random sampling. Data were collected through structured questionnaires, in-depth interviews, participant observations, and focus group discussions. Data analysis used descriptive and inferential statistics for quantitative data, as well as thematic analysis for qualitative data. The research results show that AAL cadets have a good level of PEK knowledge (score 78.6/100), high self-efficacy (3.68/5), and good operational readiness (3.72/5). As many as 85.6% of cadets acknowledge the very high benefits of PEK learning. The five main themes of benefits identified include: the development of operational technical competencies (37.2%), the enhancement of leadership abilities in critical situations (24.8%), the formation of mental resilience (18.9%), the development of quick decision-making skills (11.4%), and the improvement of a sense of responsibility for safety (7.7%). Cadets with good PEK knowledge demonstrate superior performance with a response speed 32 seconds faster, an error rate 23.4% lower, and an emergency communication score 18.2% higher. Factors influencing the effectiveness of PEK learning include the quality of instructors and teaching methods (β = 0.34), the frequency and variety of emergency simulations (β = 0.28), which together can explain 74.8% of the variance in learning effectiveness. This study provides recommendations for intensifying practical training, improving instructor quality, standardizing the curriculum to integrate technical and leadership aspects, and conducting continuous evaluations of the PEK learning program.

Pesantren, as the oldest Islamic educational institutions, face complex challenges in environmental health management, primarily due to high residential density, limited sanitation infrastructure, and varying practices of Healthy and Clean Living Behaviors (PHBS). Although the religious concept of taharah (purity) serves as a foundation for cleanliness, there is a lack of in-depth research examining the integration of religious values, infrastructure conditions, and management systems in shaping the daily hygiene experiences of santri (students).This study aims to explore the santri's experience regarding environmental health management in pesantren, focusing on the integration of hygiene, sanitation, and Islamic religious values, while also identifying factors and challenges related to PHBS practices. This qualitative research, utilizing a descriptive phenomenology design, collected data through in-depth interviews with three female santri informants (with 8–9 years of boarding experience). Data analysis was conducted using the six-phase thematic analysis method by Braun & Clarke (2006).The study identified five main themes: (1) Infrastructure is quantitatively adequate but faces operational issues (queues, seasonal clean water scarcity); (2) PHBS practices show positive behavioral changes (self-reliance) but waste management remains traditional; (3) The religious value of taharah acts as a strong intrinsic motivation; (4) The management system involves multi-level roles (kiai-ustaz-administrators) that face consistency challenges; and (5) Main obstacles include limited facilities, varying levels of santri awareness, and disparity in educational programs. Poskestren (Pesantren Health Post) represents an institutional effort to provide basic health services.Environmental health management in pesantren requires a holistic approach, integrating infrastructure improvement and sustainable waste management systems, alongside developing education that unites Islamic religious values with modern health knowledge. Optimizing the religious strategy and strengthening national monitoring/standardization systems are key to program sustainability.

The reliability of sterilization equipment, such as autoclaves, is essential to ensure patient safety, infection control, and operational continuity in healthcare facilities. Damage or malfunction of autoclaves may disrupt sterilization processes and pose significant risks to medical services. This study aims to develop an expert system for autoclave damage detection using the fuzzy logic method to support faster and more accurate diagnostic decision-making. The proposed system applies fuzzy inference to evaluate the level of damage based on input symptoms provided by users. By handling uncertainty and varying symptom intensities, the fuzzy logic approach enables proportional assessment rather than rigid rule-based classification. The system was designed through knowledge acquisition from technical experts and implemented using fuzzy membership functions and inference rules to determine damage severity levels. Experimental testing was conducted to evaluate system performance and diagnostic accuracy. The results indicate that the expert system successfully generated diagnosis outputs for all tested scenarios, achieving functional diagnostic accuracy within the defined test cases. The system was also able to calculate a quantified damage severity value of 11.6235981% based on the given symptoms, demonstrating its capability to assess damage levels numerically and objectively. Furthermore, the developed system significantly reduces the time required for damage detection compared to manual diagnostic procedures. Automating the evaluation process, it assists electromedical technicians in identifying faults more efficiently and taking preventive or corrective actions promptly. Overall, the implementation of a fuzzy logic-based expert system provides an effective, accurate, and practical solution for improving autoclave maintenance management and supporting healthcare service reliability.

The Asahan River in North Sumatra holds significant potential as an ecotourism destination for whitewater rafting, featuring Class IV-V+ rapids that attract both domestic and international tourists. This study aims to analyze the potential and development strategies for ecotourism in the Asahan River using the Ecotourism Opportunity Spectrum (ECOS) approach with the addition of a socio-economic sustainability variable. This approach evaluates seven key components: accessibility, attractions, infrastructure, social interaction, skill and knowledge levels, related resources, and visitor impact. Data were collected through observation, interviews, questionnaires, and documentation, and analyzed using a descriptive qualitative method. The results indicate that the Asahan River is classified as an Eco Specialist, with high natural appeal but requiring improvements in accessibility and community participation. Socio-economic sustainability assessments reveal that economic benefits are not evenly distributed, and local community involvement in tourism management remains low. Proposed strategies include improving infrastructure, training local communities, digital promotion, and strengthening stakeholder collaboration to establish a sustainable tourism destination.

The phenomenon of sibling rivalry and its impacts encourage the need for efforts to prevent it. The purpose of the study was to describe the characteristics of pregnant women, the level of knowledge of pregnant women about sibling rivalry, the level of behaviour of pregnant women in preventing sibling rivalry, and analyze the relationship between knowledge of pregnant women and behaviour in preventing sibling rivalry. The research method used a quantitative approach with a correlational type. The population was pregnant women who had children aged a maximum of 3 years and checked their pregnancy at the Kagok Semarang Health Center. The number of samples was 63 people. The side technique used total sampling. Data were obtained using a questionnaire and then analyzed with descriptive statistics and the Fisher exact test, a statistical test used to determine if there are nonrandom associations between two categorical variables. The results of the study were the characteristics of pregnant women, the majority aged 20-35 years, parity less than or equal to 3 births, high school education, working and family income according to the UMR. The level of knowledge of pregnant women about sibling rivalry tended to be less good, and the level of behaviour of pregnant women in preventing sibling rivalry tended to be quite good. There was a very significant relationship between knowledge of pregnant women and behaviour in preventing sibling rivalry (chi-square = 49.810 and p <0.05). The conclusion is that pregnant women's knowledge is a factor in preventing sibling rivalry behaviour.
