The rapid advancement of information and communication technology has increased the need for data security and confidentiality in digital information exchange. Various threats, such as eavesdropping, data theft, and information manipulation, require effective security methods capable of protecting message content without attracting unauthorized attention. One of the techniques used to address this issue is steganography, which conceals secret information within digital media so that the existence of the message remains undetectable. This study aims to implement the Least Significant Bit (LSB) method on digital facial images as a medium for embedding secret messages and to evaluate the quality of the resulting stego images. The system was developed using the Python programming language with a Tkinter-based graphical user interface to facilitate the processes of message embedding and extraction. Prior to embedding, the secret message was secured using an XOR encryption operation with a specific key. The embedding process was performed by modifying the least significant bits of image pixels, resulting in minimal visual distortion. Experimental results indicate that the LSB method successfully conceals secret messages while maintaining the visual quality of the cover image. The evaluation produced low Mean Squared Error (MSE) values and Peak Signal-to-Noise Ratio (PSNR) values exceeding 85 dB, indicating a very high similarity between the original and stego images. Furthermore, the hidden message could be accurately extracted using the correct key, provided that the image had not undergone compression or manipulation. Therefore, the LSB-based steganography approach on digital facial images is proven to be an effective method for enhancing information security and confidentiality.

The coffee shop industry has experienced substantial growth in recent years, creating intense competition that compels businesses to continuously enhance service performance in order to maintain customer satisfaction and market competitiveness. PT Jokopi Indonesia Group has encountered several service-related issues reflected in declining sales performance and recurring customer complaints, indicating the need for a comprehensive evaluation of service quality. This study aims to identify service attributes that fail to meet customer expectations and determine improvement priorities through the integration of the SERVQUAL and Kano methods. A quantitative approach was employed using questionnaire data collected from 50 customers who had prior experience with the company’s services. SERVQUAL was utilized to assess discrepancies between customer expectations and perceived service performance, while the Kano model was applied to classify attributes according to their contribution to customer satisfaction. The findings reveal that all evaluated attributes generated negative gap values, indicating that existing service performance has not yet reached the level expected by customers. The most critical gaps were identified in menu availability, air-conditioning and fan comfort, payment convenience, and straw availability. Kano classification further demonstrates that menu availability and thermal comfort facilities belong to the Must-Be category, meaning that failure to provide these attributes may trigger significant customer dissatisfaction. The integration of SERVQUAL and Kano highlights these attributes as the most urgent areas for improvement. The results provide managerial guidance for developing targeted service enhancement initiatives aimed at strengthening customer satisfaction, retention, and competitive advantage.

This study aims to examine the effectiveness of implementing forgiveness therapy in enhancing the personal growth of inmates at the Tangerang Class II-A Women’s Correctional Facility. The method used was a pre-experimental study with a one-group pretest-posttest design. Nine subjects aged 20-40 years were selected from 50 inmates based on low to moderate scores on the forgiveness scale and the psychological well-being scale. The intervention consisted of six sessions adapted from the forgiveness model developed by Enright and Fitzgibbons. Data analysis utilized a paired-sample t-test and the N-Gain formula. The results showed a significant increase in personal growth scores from the pretest (M = 7.00; SD = 1.225) to the posttest (M = 9.44; SD = 1.424), with t(8) = −8.315 and p < 0.001. An N-Gain value of 0.610 indicates moderate effectiveness. The follow-up measurement (M = 9.67; SD = 1.118) did not differ significantly from the post-test (p = 0.347), indicating the sustainability of the changes achieved. Forgiveness scores also increased from 65.33 (pre-test) to 86.67 (post-test) and 87.33 (follow-up), confirming the role of forgiveness as a psychological mechanism for personal growth. These findings support the integration of structured forgiveness therapy into correctional programs for women’s prisons.

Vomitus is the forceful expulsion of gastric contents through the mouth, commonly occurring in children as a clinical manifestation of gastrointestinal diseases. Based on medical records of RSUD dr. Soeselo, Tegal Regency, vomitus cases increased to 355 cases in 2025. Therefore, comprehensive nursing care is needed to address problems arising from vomiting in children. This study used a descriptive method in the form of a case study through a nursing process approach, aimed at describing nursing care for a pediatric patient with vomitus. Three nursing diagnoses were identified in An. A with vomitus: Nausea related to gastric irritation/stimulation of the vomiting center, Risk of Fluid Imbalance related to repeated vomiting, and Knowledge Deficit related to lack of information exposure. Nursing interventions provided included Vomiting Management, Fluid Management, and Health Education. After three days of nursing implementation, all three nursing diagnoses were resolved, marked by the disappearance of nausea, improved appetite, normal hydration status (moist mucosa, good skin turgor, pulse 88x/minute), and the patient's mother and patient being able to understand and re-explain health education material about vomitus.

This study aims to analyze the impact of nickel mining activities on the religious life of the community in West Kabaena District, Bombana Regency. The research employed a qualitative method with a descriptive approach to obtain an in-depth understanding of the social and religious changes occurring within the community. Data were collected through interviews, observations, and documentation involving religious leaders, community leaders, youth representatives, and mining workers. The collected data were analyzed through data reduction, data display, and conclusion drawing. The findings indicate that nickel mining activities have not diminished the community’s understanding of environmental stewardship as a religious responsibility. However, increasing economic dependence on the mining sector has gradually reduced public concern for environmental preservation. In the religious sphere, mining activities have contributed positively by supporting the construction and improvement of worship facilities and religious programs. Nevertheless, work-related demands have reduced the participation of some community members in religious activities. Furthermore, mining activities have affected social solidarity within the community. Values such as brotherhood, mutual cooperation, and social care remain preserved, although changes in social interaction patterns and widening economic disparities have become increasingly apparent. The study concludes that nickel mining activities generate both positive and negative impacts on the religious life of the West Kabaena community. Therefore, balanced policies integrating economic development, environmental sustainability, and religious values are essential to promote sustainable community welfare and strengthen social harmony.

The urgency of this research stems from the knowledge gap regarding contextual factors contributing to the underuse of learning media in rural elementary schools, which has not been adequately addressed in previous research, which has tended to focus on urban contexts. This study aims to examine teachers' perceptions at Sugayang Public Elementary School regarding the underuse of learning media in the learning process, as well as the factors that contribute to it. The method used was a descriptive qualitative method, utilizing in-depth interviews as a data collection technique. The data were then analyzed using data reduction, data display, and conclusion drawing techniques according to Miles and Huberman. The results showed that teachers experienced difficulties in using technology, difficulties in creating learning media, and the perception that using media was time-consuming. This reveals an important pattern that the underuse of learning media is a systematic problem rooted in the TPACK gap that is not supported by practical time management solutions. These findings imply that changes in learning practices will not occur simply through the provision of generic technology tools or training; rather, bottom-up and contextual solutions are needed. The novelty of this research lies in the in-depth qualitative approach applied to the under-researched context of rural elementary schools, which has not been studied before. This research contributes through recommendations for the implementation of a peer-mentoring program and the development of a ready-to-use digital learning media bank, thus offering valuable insights for future research with relevant stakeholders.

Nursing diagnoses that emerged in the patient with Social Isolation: Withdrawal were Social Isolation as the Core Problem, Low Self-Esteem as the Cause, Risk of Hallucination as the Effect, and Self-Care Deficit as a concurrent problem. Interventions were only carried out on Social Isolation and Self-Care Deficit problems, consisting of SP 1 through SP 3 for Social Isolation and SP 2 for Self-Care Deficit: Grooming. After nursing implementation for 4 days, of the 4 nursing diagnoses that emerged, only 2 nursing diagnoses were intervened, namely Social Isolation and Self-Care Deficit. SP 1 through SP 3 for Social Isolation and SP2 for Self-Care Deficit: Grooming were competently achieved. This indicates that the goals of the Implementation Strategy provided were achieved cognitively, affectively, and psychomotorically.

This study aims to provide the benefits of a psychological approach in education through a learning adjustment strategy based on the developmental stage and age limits of students. The study used a library method with a qualitative descriptive-analytical approach through a review of educational psychology literature, cognitive development theory, national education regulations, and various relevant scientific journals. The results of the study indicate that learning effectiveness is greatly influenced by the alignment between material, teaching methods, and students' psychological readiness. Piaget's cognitive development theory indicates that elementary school-aged children are at the concrete operational stage, thus requiring contextual learning, the use of real-life media, and active interaction in the learning process. This study also found that age limits in the education system have an important function as a means of synchronizing students' biological, emotional, social, and intellectual readiness with learning targets. Through the "Psychological Navigation" model, this study offers a strategic framework for educators to create adaptive, humanistic learning that is oriented towards optimal student development. The implications of this study emphasize that teachers need to understand the individual characteristics of students so that the educational process does not only focus on academic achievement, but also supports the psychological well-being and character formation of students as a whole.

The risk of accidents in the school environment is quite high, but the ability of the School Health Business Team (UKS) to handle emergencies is often still limited to theoretical knowledge without adequate practical skills. This study aims to analyze the influence of the Role Playing and Emergency Simulation (RANGGA) method on the improvement of the knowledge and skills of the UKS Team in junior high school. This study used a quasi-experiment design with a pre-post test with control group design. The research sample amounted to 60 respondents which were taken by purposive sampling technique. The intervention group was given RANGGA training, while the control group was given conventional education. The data were analyzed using the non-parametric Wilcoxon Signed Ranks Test because the data distribution was abnormal. In the intervention group, there was an increase in the average knowledge score from 88.7 to 97.9 and the skill score from 87.99 to 97.98. The results of the Wilcoxon test showed a significance value of p<0.001 for both variables in the intervention group, indicating a very strong influence of the RANGGA method. In contrast, although the control group experienced an improvement, the variation in scores remained higher and the improvement was not as significant as the intervention group. The RANGGA method is significantly effective in improving the emergency competence of the UKS Team through an experiential learning approach. It is recommended for school institutions to integrate simulation and role play methods in the UKS training curriculum to ensure optimal emergency response readiness.

During verification, the QR Code is scanned and the extracted token is compared with records stored in the database. Experimental results demonstrate that the proposed system is capable of verifying document authenticity accurately and efficiently. Furthermore, Black Box Testing confirmed that all implemented functions operated as expected. Therefore, the integration of Base64 and Pepper contributes to improving the security and dependability of digital document verification.

Primary dysmenorrhea frequently disrupts the academic and daily activities of adolescent girls. This study evaluated the effectiveness of a 5-minute warm compress application in reducing menstrual pain intensity. A quasi-experimental study with a one-group pretest-posttest design was conducted on 42 female students of SMAN 28 Batam selected through purposive sampling. Participants applied a warm compress (40–45 °C) to the lower abdomen for 5 minutes. Pain intensity was measured using the Numeric Rating Scale (NRS) before and after the intervention. Data were analyzed using the Wilcoxon Signed-Rank test. Before the intervention, 42.9% of participants reported severe pain (NRS 7–10). After the 5-minute application, the severe pain category disappeared entirely (0%), with 57.1% of subjects shifting to the mild pain category (NRS 1–3). Statistical analysis showed a significant reduction in dysmenorrhea intensity (p < 0.001). A 5-minute warm compress application is a rapid and effective non-pharmacological intervention for relieving primary dysmenorrhea in adolescents. Its practicality makes this method a feasible self-care strategy to implement in school settings.

Due to its effect on the caliber of generations to come, iron deficiency anemia in teenage females is one of Indonesia's most pressing reproductive health concerns. Adolescents' awareness to autonomously adopt preventative actions is shaped mostly by their knowledge. The purpose of this research is to determine whether there is a correlation between the prevalence of anemia among teenage females in Boyolali Regency and their degree of education. Using a cross-sectional design, this study employs quantitative correlational analytic methods. An accidental sampling approach was used to obtain a sample size of 80 respondents from the population of seventh grade female pupils. A digital POCT device was utilized to quantify the incidence of anemia variables based on hemoglobin (Hb) levels, while a structured questionnaire instrument was employed to gather data for knowledge variables. The Chi-Square test was used to assess the bivariate data analysis. According to the univariate analysis, 62.5% of the participants (50 respondents) had a decent level of knowledge, and 73.8% of the participants (59 respondents) did not suffer from anemia (Hb > 12 g/dL). With a p-value of 0.000 (p < 0.05), the results of the bivariate test were generated. Anemia is more common among female students at MTs Al Ihsan Doglo who have a higher degree of expertise, according to this study. School districts should keep an eye on students' iron pill use and improve their nutrition education programs.
