Students at the High School level often face various emotional and psychological challenges, such as academic stress, social pressure, and personal crises, which can negatively affect their mental well-being. To overcome this issue, community service aims to implement Psychological First Aid (PFA) training which provides students with understanding and skills in providing psychological support to colleagues. The focus of this service is to increase awareness of the importance of mental health support in the school environment. The method used involves pretest questionnaires, theory sessions, role plays, group discussions to help students master the basic principles of PFA through real situation simulations and ends with a post test. The results of PKM activities are (1) most participants gained an increased understanding of Psychological First Aid (PFA); (2) Most participants easily practiced Psychological First Aid (PFA) with their friends during role play sessions. The conclusions from this service are (1) increasing the knowledge and skills of female students at SMA Negeri 3 Sentani in applying Psychological First Aid (PFA) to their peers; (2) Collaboration between FIK UNCEN and SMA Negeri 3 Sentani; (3) carrying out community service activities as a lecturer's academic obligation.

The training of Community Sports Cadres on Organizing Safe and Healthy Matches is motivated by the increasing number of sporting events which often ignore safety and health aspects. This activity involved 40 participants from the local community and the South Jayapura district youth organization. The aim of the activity is to increase understanding and skills in organizing matches in accordance with safe and healthy standards.  The training method applied includes several steps, namely a pretest to measure participants' initial knowledge, followed by an education and training session that includes theory and practice, then ending with an evaluation. After the session, a posttest was carried out to assess the increase in participants' understanding. The evaluation results showed a significant increase in participants' knowledge; The percentage of participants who understood the material rose from 67% of participants who understood and 33% of participants who did not understand during the pretest to 93% of participants who understood and the remaining 7% who did not understand after education and training. The conclusion of this activity shows that the training succeeded in achieving its goal of increasing the capacity of safe and healthy sports cadres. The resulting suggestion is the need to carry out similar training on a regular basis to continue to educate and empower the public in the safety and health aspects of organizing sports.
