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.

This study investigated how employee engagement and work–life balance influenced turnover intention, with rewards examined as an intervening mechanism, among Generation Z employees in a state-owned enterprise context. A quantitative explanatory design was applied using a census approach involving all 36 Generation Z employees at PT PLN (Persero) Pematangsiantar. Data were collected through structured questionnaires measured on a five-point Likert scale and were analyzed using multiple regression and mediation-based path analysis in SPSS. The findings showed that employee engagement and work–life balance significantly predicted perceived rewards, and all three variables exerted significant effects on turnover intention. Moreover, rewards partially mediated the effects of employee engagement and work–life balance on turnover intention, indicating that positive work experiences reduced employees’ intention to leave when they were reinforced by fair and meaningful reward practices. However, the small sample size limited the generalizability of the findings beyond the organizational setting studied. This study contributes by demonstrating that retention of Generation Z employees is shaped not only by psychological attachment and work–life balance, but also by how organizations institutionalize recognition and value exchange through reward systems, particularly in public service and state-owned enterprises.

A decrease in the height of the uterine fundus is an important indicator of a normal uterine involution process after childbirth. Delayed reduction of fundal height may lead to uterine subinvolution, which increases the risk of postpartum hemorrhage, particularly in post–cesarean section mothers. Early breastfeeding and early mobilization are recommended interventions to support uterine contraction, prevent vaginal bleeding, and accelerate uterine involution. This study aimed to examine the effect of early breastfeeding and early mobilization on reducing the height of the uterine fundus in post–sectio caesarea mothers treated in the Amaryllis SMC Room at Telogorejo Hospital. The study employed a quasi-experimental design with a one-group pretest–posttest approach. The population consisted of 523 post–cesarean section mothers hospitalized at SMC Telogorejo Hospital between January and November 2023. Data were collected using structured observation sheets to measure fundal height before and after the interventions. The results showed that the average uterine fundal height before early breastfeeding and early mobilization was 19.74 cm above the symphysis, while after the interventions it decreased to an average of 12.49 cm above the symphysis. Statistical analysis indicated a significant effect of early breastfeeding and early mobilization on the reduction of uterine fundal height (p = 0.000). These findings highlight the importance of implementing early breastfeeding and mobilization as part of postpartum nursing care to support uterine involution and reduce the risk of complications in post–cesarean section mothers.

Divorce is the legal and religious termination of a husband-wife relationship. This severance of the relationship can have psychological consequences, making children more susceptible to depression. These psychological impacts include deep sadness, resulting in depression, feelings of loss, shame, anger, disappointment, denial, self-acceptance, and feelings of blame toward the parents. These psychological impacts are naturally the result of the support, emotional support, and presence of the parents before, during, and after the divorce. This study employed a qualitative research method with a phenomenological approach, conducted through semi-structured interviews. The aim is to raise awareness among readers that divorce not only impacts the husband and wife but also the psychological impact on children, which is often considered unimportant. However, the mental health of children after divorce is a crucial issue that requires attention. This is where the role of parents is crucial in shaping their character and psychological development. This study concludes that children who are victims of divorce tend to seek out activities outside the home, as the integrity of their home is no longer there. Children experience sadness and loss most acutely. Furthermore, children are more wary of future relationships due to a loss of trust in the meaning of romantic relationships. Low self-acceptance also makes it difficult for children to control their emotions.
