This study aims to analyze the impact of recruiting Vocational High School (SMK) Mechanical Engineering graduates on the quality of education at the Naval Academy (AAL) Technical Corps. Using a mixed methods approach with quasi-experimental design, the research involved 160 Naval Academy cadets consisting of 80 cadets with SMK Mechanical Engineering background and 80 cadets with Senior High School Science background as control. Data were collected over 4 semesters through academic achievement instruments, technical competency tests, academic adaptation scales, and in-depth interviews. Results showed that although SMK cadets experienced initial academic adaptation challenges with lower GPA in the first semester (3.12 vs 3.28), this gap narrowed over time and even showed positive trends in the final semester (3.41 vs 3.38). SMK cadets demonstrated significant superiority in technical subjects such as Ship Propulsion Systems (85.2 vs 78.9) and Auxiliary Machinery (83.7 vs 76.4), particularly in practical components. In terms of social adaptation, the SMK group consistently showed higher scores throughout the research period. Learning style analysis revealed dominance of kinesthetic (47%) and visual (31%) preferences in the SMK group, different from the SHS group which preferred read/write (38%) and auditory (29%). These findings indicate that recruiting SMK Mechanical Engineering graduates has a positive impact on the quality of AAL education, particularly in applied technical competencies and social adaptation abilities. Educational background diversity can become a strategic strength if managed through appropriate bridging programs and diversification of learning methods that accommodate the diversity of cadet learning styles.

This is because modern warfare has evolved from conventional physical conflicts to battles that encompass the domains of information, cybersecurity, and technological supremacy. In an effort to build a strong, sophisticated, and autonomous defense system, a nation needs to prioritize reducing dependency on other countries through achieving independence in the provision of Main Weapon System Tools (Alutsista). The Naval Technology College (STTAL) plays a vital role in advancing research activities and producing high-quality human resources as a long-term defense investment capital that can be optimized by the Indonesian Navy (TNI AL). This study examines the impact of innovation and integrated technological readiness in STTAL's research outcomes on the achievement of TNI AL's defense equipment independence. The research methodology employs a quantitative approach with Structural Equation Modeling (SEM) analysis techniques using the SmartPLS 4 application. The study involves four key variables: Innovation (X1, Z), Technological Readiness (X2), STTAL Research Outcomes (Y1), and TNI AL Defense Equipment Independence (Y2). The research findings reveal that: (1) the innovation variable has a significant impact on STTAL's research outcomes with an effect magnitude of 0.065, (2) the technology readiness variable shows a very significant influence on STTAL's research outcomes with an effect magnitude of 0.874, (3) there is a significant mediating effect of technology readiness through innovation as a mediator on STTAL's research outcomes with an effect magnitude of 0.026, and (4) STTAL's research outcomes have a very significant impact on the independence of the TNI AL's defense equipment with an effect magnitude of 1.318.

This research aims to analyze optimal educational strategies for cadets of the Indonesian Navy Academy's Technical Corps Generation Z, considering their unique learning characteristics without compromising military values. Using a mixed-method approach with a sequential explanatory design, the research involved 180 cadets as quantitative respondents and 26 participants for the qualitative phase (15 cadets, 8 instructors, 3 AAL leaders). Data were collected through structured questionnaires, in-depth interviews, focus group discussions, and participatory observations. Quantitative analysis used descriptive statistics, comparative tests, and multiple regression, while qualitative data were analyzed thematically. The results show that Generation Z cadets have a preference for visual learning (68%), interactive technology-based learning (M=4.1), and require instant feedback. Blended learning proved to be the most effective with an GPA of 3.45 and an engagement rate of 85%, compared to traditional learning (GPA=3.18, engagement=61%). Predictor factors of learning effectiveness include interactivity (β=0.412), technology use (β=0.298), periodic feedback (β=0.267), and content relevance (β=0.231). The research produced the "ADAPTIVE" learning model, which integrates modern technology with traditional military values. This model can enhance educational effectiveness while maintaining the essence of military training, providing both theoretical and practical contributions to the transformation of military education in the digital era.

The Naval Academy has many options in carrying out MOB practical training. The training is carried out in 2 places, namely at Kal Kadet and at the Andromeda Building "Bridge Simulator". However, the Andromeda Building has never been used at all in MOB practical training even though the Andromeda Building has the potential for sailor corps cadets to carry out MOB practical training. The time constraints often clash with regimental activities so that the cadets do not get maximum results. To reduce the collision between practical training and regimental activities that shorten the time during practical training, the researcher analyzed using the SWOT method so that it would produce several alternatives to overcome this situation. The stages that will be carried out to optimize the time given by the Institution are by utilizing the Andromeda Building to carry out MOB practical training.

securing the waters in the Sulawesi Sea against illegal fishing in order to increase the utilization of potential maritime resources. The main point of this study is that Indonesia has very abundant maritime resources and this is what triggers illegal fishing activities, especially in the Sulawesi Sea area, both by local citizens and foreign citizens. In response to this, agencies such as the Indonesian Navy (TNI - AL), the Maritime Security Agency (BAKAMLA), the Ministry of Marine Affairs and Fisheries (KKP) and other agencies must be directly involved in these activities so that the Indonesian maritime territory and maritime resources in the Indonesian seas are not damaged and disturbed by these activities.

The development of science and technology has caused the military forces of many countries to spend a lot of money and energy on research and development of automated, multi-faceted and effective (including lethal) technology. From a maritime perspective, this development has attracted widespread interest from many navies in underwater technology such as submarines and unmanned submarines. Modern submarines are now capable of moving at high speeds with very low noise levels, in addition to being able to carry weapons with very high destructive power and carry out diving operations for long periods of time. At the same time, modern unmanned underwater vehicles are now capable of carrying out various types of operations, including surveillance, minelaying, underwater surveys, and even the ability to carry long-range weapons up to thousands of kilometers away. It is undeniable that the development of other countries' navies is a real threat to Indonesia. To overcome this problem, an underwater surveillance system is needed in Indonesian waters, especially in deep waters which are likely to be used by other countries such as ALKI to carry out covert operations. This underwater surveillance system must utilize existing technological developments in order to carry out its functions effectively and sustainably, especially by using autonomous underwater vehicles (USVs). The use of USV in surveillance systems will save a lot of costs because it does not waste budget on expensive logistics, personnel, maintenance, and spare parts. This research is a research and development using mixed research methods (qualitative and quantitative) with research products in conceptual form. In this underwater surveillance system concept, USV will automatically conduct underwater contact surveillance along the ALKI II water body using sensors and software integrated into the USV.

This thesis presents a conceptual analysis of the utilization of Unmanned Surface Vehicle (USV) technology to support the Indonesian Navy (TNI AL) in maintaining maritime security within the ALKI II (Indonesian Archipelagic Sea Lane II) region, in order to enhance operational efficiency and effectiveness. USVs are surface vessels that operate autonomously or are remotely controlled without onboard human presence. These vehicles can be operated from land-based control stations or from other vessels. The main research question addressed in this study is how the development and application of USV technology can support the Indonesian Navy’s mission in safeguarding maritime security within the ALKI II corridor. This study considers USVs as a surveillance asset, representing a technological advancement that can significantly enhance the Navy’s surveillance and monitoring capabilities. It is expected that the implementation of USVs will contribute to improved efficiency in securing and supervising ALKI II, while also promoting effective coordination among relevant stakeholders. Ultimately, the presence of USVs may help to reduce and prevent unlawful activities in the ALKI II waters. This research employs a qualitative methodology. The findings indicate that the use of USVs enhances both operational effectiveness and efficiency, thereby supporting the Indonesian Navy’s mission to secure the ALKI II region. This study aims to provide strategic recommendations to the Indonesian Navy regarding the development and integration of USV technology. It is anticipated that such measures will serve as a significant step toward reinforcing maritime security in the ALKI II corridor.

Pneumonia detection from chest X-ray images is widely used in computer-aided diagnostic systems. However, effective clinical decision support requires not only accurate classification performance but also consideration of unequal error costs, since false negative predictions may lead to more severe consequences than false positives. In addition, prediction probabilities must be well calibrated to support threshold-based medical decisions such as triage and patient escalation. This research investigates asymmetric misclassification costs and probability calibration for binary classification (PNEUMONIA vs. NORMAL) using the Hugging Face dataset hf-vision/chest-xray-pneumonia. The proposed framework utilizes a ResNet-18 architecture integrated with cost-sensitive learning through weighted cross-entropy loss (FN:FP = 5:1), threshold optimization based on validation data to reduce expected cost, and post-hoc temperature scaling for improving probability calibration. Experimental results on the independent test set indicate that the cost-sensitive approach enhances specificity and decreases expected cost compared to the conventional cross-entropy baseline. Furthermore, temperature scaling improves the reliability of probabilistic predictions, as demonstrated by better negative log-likelihood and Brier score values. The study also explores selective prediction strategies to balance prediction coverage and risk reduction, complemented by Grad-CAM visualizations and structured failure-case analysis for qualitative assessment. Overall, the findings demonstrate that incorporating cost-aware decision thresholds and calibrated probability estimates can serve as lightweight yet effective enhancements for chest X-ray classification systems in clinical decision-support applications.

Anxiety is a common psychological response experienced by mothers during labor, which can impact both maternal and neonatal outcomes. Husband's support, as a form of social support, is believed to reduce maternal anxiety levels during delivery. However, empirical evidence in Indonesia, particularly at Obi General Hospital, is still limited. This study aimed to analyze the effect of husband's support on maternal anxiety levels during normal delivery at Obi Hospital in 2025. A quasi-experimental design with a non-equivalent control group approach was used. The study population consisted of mothers who underwent normal delivery at Obi General Hospital in 2025. A purposive sampling technique selected 30 respondents, divided into two groups: 15 respondents with husband support and 15 without. The research instrument was a validated anxiety level questionnaire, and data were analyzed using the Chi-Square test with α = 0.05. The majority of respondents were aged 25-34 years (60%), multigravida (53.3%), had a high school education (50%), were unemployed (60%), and had normal deliveries without complications (83.3%). In the group with husband's assistance, 80% experienced mild stress, 20% moderate stress, and none severe stress. In contrast, in the group without husband support, 26.7% experienced mild stress, 46.7% moderate stress, and 26.7% severe stress. The Chi-Square test yielded a p-value of 0.008 (p < 0.05), indicating a significant relationship between husband's support and maternal anxiety levels. In conclusion, husband’s support significantly reduces maternal anxiety during normal labor. Health facilities should implement policies that encourage active husband involvement in labor to improve maternal outcomes and the birth experience.

The third trimester of pregnancy is a critical period with increased risks of obstetric complications, necessitating adequate knowledge of pregnancy danger signs. The Pregnant Women's Class (Kelas Bumil) is a preventive and educational initiative in antenatal care designed to enhance knowledge and preparedness among pregnant women. This study aimed to assess the impact of the Pregnant Women's Class on the knowledge of pregnancy danger signs and changes in hemoglobin levels among third-trimester pregnant women. Using a quasi-experimental pretest-posttest design, the study involved 30 pregnant women selected through purposive sampling. Knowledge was assessed via structured questionnaires before and after attending the class, while hemoglobin levels were measured at both intervals. Univariate and bivariate analyses were conducted, with the Wilcoxon test used for comparing pre- and post-intervention data (p < 0.05). Results revealed a significant increase in knowledge levels, with most women showing good knowledge after the intervention. Hemoglobin levels also improved significantly (p = 0.001). These findings demonstrate that the Pregnant Women's Class effectively enhances both cognitive knowledge and health status in pregnant women. In conclusion, strengthening and sustaining the Pregnant Women's Class should be a continuous part of integrated antenatal care to improve maternal health outcomes.

Background: Exclusive breastfeeding is essential for infant growth, immunity, and overall health. However, many breastfeeding mothers experience difficulties in maintaining exclusive breastfeeding due to improper breastfeeding techniques, low maternal knowledge, and lack of guidance from health workers. Proper application of breastfeeding techniques, including correct latch-on, positioning, and frequency, can improve breastfeeding consistency and prevent early weaning (Sari, 2020; Putri, 2021). Objective: This study aimed to determine the effect of the application of breastfeeding techniques on the consistency of exclusive breastfeeding in breastfeeding mothers at the Dambalo Community Health Center. Methods: A quantitative, pre-experimental study with a one-group pretest-posttest design was conducted. Thirty breastfeeding mothers were selected using purposive sampling based on inclusion criteria, including mothers of infants aged 0–6 months who were willing to participate and had no medical conditions preventing breastfeeding. Results: All 30 participants (100%) applied the recommended breastfeeding techniques after the intervention. Following the intervention, 27 mothers (90%) consistently practiced exclusive breastfeeding, while three mothers (10%) showed partial improvement. Statistical analysis using the Wilcoxon signed-rank test revealed a significant difference in exclusive breastfeeding consistency before and after the intervention (p = 0.000), indicating that the application of proper breastfeeding techniques significantly improved breastfeeding practices. Conclusion: The application of breastfeeding techniques has a significant positive effect on the consistency of exclusive breastfeeding among mothers at the Dambalo Community Health Center. Structured guidance and practical support from health workers, particularly midwives, are essential to improve maternal skills, reinforce proper practices, and ensure the health and growth of infants.

Danger signs of pregnancy are signs or symptoms indicating that the mother or fetus is in danger. Knowledge of danger signs of pregnancy is a factor that influences the high Hamilton Anxiety Rating Scale (HARS) score of mothers in labor. This study aims to determine the relationship between mother's knowledge about pregnancy danger signs and HARS scale scores for mothers in childbirth in the Lamasi Health Center Work Area. This is a quantitative study using an observational cross-sectional approach. The population and sample were 32 people using total sampling technique. Data collection used questionnaires and observation sheets. Analysis used chi-square test. The results showed that there was a relationship between the mother's knowledge of pregnancy danger signs and HARS scale scores of mothers in labor in the Lamasi Health Center Work Area with a p value = 0.021 < α value = 0.05. It is hoped that health institutions can increase the knowledge of health workers and the community regarding pregnancy danger signs and the HARS score of mothers in labor.
