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.

Enhanced oil recovery (EOR) is the recovery of oil remaining in a reservoir after primary and secondary recovery methods because it has been exhausted or is no longer economical, using thermal, chemical or mixed gas processes. Most conventional methods are not suitable for extracting oil from high temperature and high pressure (HTHP) reservoirs due to chemical degradation in the environment. Alternatively, electromagnetic (EM) energy is used as a thermal method to reduce oil viscosity in reservoirs, thereby increasing oil production. The application of nanotechnology in EOR is also investigated. In this study, we investigate a non-invasive method by injecting dielectric nanofluids into an oil reservoir simultaneously with electromagnetic irradiation, with the aim of increasing oil production by causing disruption at the oil-water interface. During core displacement tests, ZnO and Al2O3 nanofluids were shown to obtain higher amounts of residual oil than commercial sodium dodecyl sulfate (SDS) surfactant without EM irradiation. With EM irradiation, more residual oil is obtained compared to without irradiation. It has also been shown that changing the viscosity of dielectric nanofluids during electromagnetic irradiation increases sweep efficiency, resulting in higher oil recovery.

A mixed-use building refers to a combination of several different functions within a single structure, such as residential, office, shopping, and recreational functions built on one site. Designing a mixed-use building requires careful planning and consideration of various factors such as functional needs, aesthetics, and energy conservation. Additionally, the design of mixed-use buildings incorporates various functions within a single area. Floor slabs and beams use plain reinforcing steel with a quality of Fy = 240 MPa (Ø8mm). The concrete cover is taken as 20 mm. From the design results, several thickness types of slabs were obtained according to the load requirements that must be accommodated above them. The following are the moments acting on the floor slabs and beams. The reinforcement calculations are performed using the capacity strength design method according to SNI 2847-2019. The capacity design concept involves controlling the formation of plastic hinges at predetermined locations. The SAP2000 program can directly calculate the feasibility of the structural dimensions and the amount of reinforcement needed from the input program results. In the SAP2000 program, the concrete code used is the American concrete code ACI-318-05/IBC 2003, which differs in some respects from the concrete code in Indonesia SNI 2847-2019. Adjustments need to be made to comply with the regulations in Indonesia. Internal forces from the SAP2000 program are selected from load combinations that generate the maximum moments at the column face. The flexural and shear reinforcement for beams can be directly read from the SAP2000 output in the form of information on the required area of reinforcement.

WHO's Stepwise approach includes three phases: assessment, development, and implementation & evaluation. The thematic analysis identified seven major barriers and five supporting factors in reproductive health. The developed model integrates five components: comprehensive education, youth-friendly services, peer education empowerment, family and community engagement, and policy advocacy. Quasi-experimental results showed significant improvements in knowledge (67.3%), positive attitudes (54.8%), and safe reproductive health practices (43.6%) in the intervention group compared to the control (pfeasibility of the WHO Stepwise-based model as a systematic, evidence-based, and multisectoral framework that can be replicated for sustainable reproductive health prevention programs).

This study explores the role of peer mentoring as a strategy to reduce student dropout rates and strengthen social support networks in universities. Using a mixed-methods approach that combined quantitative surveys and qualitative interviews, the research examined students’ sense of belonging, academic motivation, persistence intention, and access to emotional and academic support. The findings indicate that peer mentoring significantly enhances students’ sense of community, increases their academic motivation, and strengthens their commitment to continue their studies. Compared to other retention strategies such as academic counseling or financial support, peer mentoring provides unique advantages by fostering ongoing peer-to-peer relationships and expanding social networks. Moreover, the study found that mentor–mentee interactions create a safe space for students to share academic challenges, personal concerns, and coping strategies, which contributes to improved well-being and greater confidence in navigating university life. Peer mentoring also offers opportunities for skill development, including communication, collaboration, and self-regulation, making it beneficial not only for mentees but also for mentors. These results suggest that peer mentoring not only mitigates dropout risks but also contributes to building long-term resilience and a supportive learning environment for students. Therefore, universities are encouraged to integrate structured peer mentoring programs into their retention initiatives to promote student success and holistic development.
