Introduction: Smartphone use has increased substantially in higher education and is widely used by university students for both academic and non-academic activities. Prolonged smartphone use combined with poor posture may increase mechanical load on cervical structures and lead to neck pain. This study aimed to examine the relationship between smartphone use and neck pain intensity among students at IKES Suaka Insan. Methods: A quantitative cross-sectional study was conducted involving 55 undergraduate nursing and physiotherapy students selected using cluster sampling. Smartphone use was assessed using a structured questionnaire, while neck pain intensity was measured using the Visual Analog Scale (VAS). Data were analyzed using Spearman’s rho correlation test. Results: The analysis showed a weak negative association between smartphone use and neck pain intensity (r = -0.16), with a p-value of 0.20 (>0.05), indicating no statistically significant relationship. Conclusion: There was no significant association between smartphone use and neck pain intensity among students. Future studies should include ergonomic posture and duration of smartphone use as additional variables.

 The rapid adoption of smartphones among Indonesian digital natives has increased reliance on biometric authentication systems. However, empirical evidence regarding the relationship between user satisfaction and security risk awareness remains limited, particularly in developing-country contexts. This study investigates the behavioral dynamics of biometric security perception among 266 respondents, consisting of 221 high school students and 45 university students in Indonesia. A Python-based computational pipeline incorporating Akaike Information Criterion (AIC) validation and 1,000-iteration stochastic bootstrapping was employed to evaluate nonlinear behavioral patterns using Polynomial Regression and Ordinary Least Squares (OLS) multivariate analysis. The results confirm the existence of a nonlinear Security Paradox. While the overall population demonstrates a positive quadratic trajectory, the university student group exhibits a concave-down parabolic relationship (a=−0.0460), indicating a decline in perceived utility beyond a specific security threshold. The identified behavioral breaking point occurs at X≈5.45 (95% CI: 2.99–20.77), suggesting that excessive security hardening may reduce perceived usability and increase cognitive friction. Furthermore, the ablation analysis reveals that security risk awareness (p<0.001) is the strongest predictor of user satisfaction, exceeding the influence of daily usage intensity. Segment-level analysis further demonstrates behavioral divergence between respondent groups. High school students exhibit relatively uniform satisfaction toward biometric systems, whereas university students display greater variability and more critical perceptions regarding authentication friction. These findings indicate that highly rigid security configurations may become less effective for users with higher digital literacy and risk awareness. This study contributes a computationally validated behavioral framework for understanding security–utility trade-offs and provides a conceptual foundation for developing adaptive, user-centric, and friction-aware biometric authentication systems.

Abstract. The rapid growth of social media has significantly changed communication patterns, self-expression, and employment opportunities, especially among younger generations. However, among vocational high school students, social media use is still largely focused on entertainment and has not been optimally utilized for skill development, personal branding, or economically productive activities. Addressing this issue, a community service program was conducted to enhance the knowledge, understanding, and practical skills of students at SMK YBPK Pare in creating creative, structured, and relevant social media content in line with the demands of the digital era in 2024. The program was implemented through the delivery of conceptual materials on social media fundamentals, content planning strategies, and effective content creation techniques. These materials were strengthened through interactive discussions and hands-on practice using smartphones and accessible editing applications. The participants included 40 students from grades X, XI, and XII, representing Generation Z with high social media usage intensity. The results showed improved student understanding of the purpose of social media, basic digital content concepts, and communicative content creation techniques. Students were able to produce simple promotional content to support school branding. In addition to technical skills, the program increased awareness of social media as a tool for self-development, digital literacy, and future employment or entrepreneurial opportunities, thereby contributing positively to students’ digital competencies and work readiness.

The development of digital technology has significantly changed students’ lives, especially in learning and entertainment activities. However, the high intensity of using electronic devices such as smartphones, tablets, and computers has increased the amount of time spent in front of screens (screen time). Excessive screen time has adverse effects on eye health (e.g., dry and tired eyes), disrupts sleep patterns due to blue light exposure, and reduces students' concentration in learning. This community service program aimed to raise students' awareness and knowledge regarding the negative impact of prolonged screen time and provide education on mitigation strategies, such as the 20-20-20 rule, screen time limitations, and healthy sleep routines. The program was conducted through educational outreach and interactive discussions involving 88 students from grades X and XI at SMA Negeri 1 Tomohon in May 2025. Evaluation was carried out using pre-tests and post-tests along with feedback questionnaires. The results showed a significant improvement in students’ understanding of screen time risks and how to manage it. Participants also demonstrated high enthusiasm, as reflected in active involvement during Q&A sessions and their adoption of the tips provided. This program is expected to be the first step in fostering healthy digital habits among students.

The study aims to find out the influence of phubbing behavior with communication intensity on visitors in the public area of M Bloc Space. The design of the study uses quantitative research with sampling techniques used with accidental samplings. The sample in this study is a visitor to the public area of M Bloc Space as an active smartphone user with a total of 70 respondents. The data collection method used is a scale of phubbing behavior and communication intensity. The results of this study show that Phubbing behavior has a positive and significant influence on Communication Intensity because the t count value is greater than the t table and the significant value is less than 0.05 so the Ha hypothesis is accepted.

Generation Z is more skilled in mastering information and technology. For generation Z, information technology such as smartphones is something that has become part of their lives, because this generation was born where access to information, especially through smartphones, has become a global culture. Therefore many children, teenagers and even adults are trapped in using smartphones. Budyatna said that with the use of smartphones, it has affected transactional processes, where often dynamic and reciprocal communication is felt to decrease in quality and quantity in direct interactions, this is influenced by the intensity of smartphone use. The intensity of using a smartphone is the level of frequency a person uses a smartphone based on pleasure from the activity. so that in the end those who are affected by the intensity of smartphone use tend to ignore the people around them and indirectly create bad ethics in direct socializing
