Online games are one of the digital entertainment activities widely favored by adolescents; however, high-intensity use can lead to psychological impacts, one of which is anxiety. Anxiety in adolescents is characterized by feelings of restlessness, irritability, difficulty concentrating, and sleep disturbances, especially when they are unable to play online games or when they experience defeat in the game. This study aimed to determine the relationship between the intensity of online game use and the level of anxiety among adolescents. This study used a quantitative design with a cross-sectional approach, involving 113 respondents selected using a cluster sampling technique. The research instruments used were the DASS questionnaire and an online game usage intensity questionnaire, and the data were analyzed using univariate and bivariate analysis. The respondents in this study were adolescents from SMAN 1 Wanadadi, most of whom were 16 years old (49.6%) and predominantly female (61.9%). The intensity of online game use was mostly in the moderate category (55.8%), while the level of anxiety was mostly in the mild category (89.0%). The results showed that most respondents had a moderate level of online game usage intensity and a mild level of anxiety. Bivariate analysis indicated that there was no significant relationship between the intensity of online game use and the level of anxiety among adolescents, with a p-value of 0.425 and a contingency coefficient value of 0.076. Therefore, it can be concluded that there is no relationship between the intensity of online game use and the level of anxiety among adolescents.

Nursing documentation is an essential part of healthcare services, playing a key role in communication, care continuity, and serving as legal evidence. The introduction of the Hospital Management Information System (SIMRS) aims to improve the efficiency of documentation processes. However, high workloads in critical areas such as the Emergency Department (IGD) and Intensive Care Unit (ICU) may influence nurse compliance with documentation protocols. This study investigates the relationship between workload and nursing documentation compliance during the implementation of SIMRS at RSUD Haji Makassar's IGD and ICU. A quantitative cross-sectional design was used, with 30 nurses participating (total sampling). The workload was assessed using the NASA Task Load Index (NASA-TLX), while compliance was evaluated through a questionnaire. The data were analyzed using Chi-Square and Fisher’s Exact Test. The results showed that the majority of respondents experienced heavy workloads (83.3%), and most had compliant documentation (96.7%). However, the statistical analysis yielded a p-value of 1.000, indicating no significant relationship between workload and documentation compliance. Based on these findings, the study recommends optimizing SIMRS usage and providing ongoing training to ensure improved compliance with nursing documentation practices.

Electricity dependence is increasing as people have easier access to electronic devices. However, this ease of access is not always accompanied by adequate energy literacy. In its Community Service program, Universitas 17 Agustus 1945 Jakarta helped to educate the residents in RW06 Kalibaru, Jakarta, about the safe and efficient use of electricity. This community service program was conducted through participatory seminar with a qualitative approach for residents. The activity used informal visual presentations and discussions in an informal atmosphere. The outreach program demonstrated residents' high enthusiasm for the efficiency of electrical equipment usage such as air conditioners, refrigerators, and water pumps. Through the discussion session, residents realized that using air conditioners with too low a power consumption actually leads to higher energy consumption because the compressor runs continuously. Participants understood that investing in automation concepts, such as using water reservoirs, provides significant long-term electricity cost savings. This outreach successfully shifted residents' paradigm from just simply seeking low prices to selecting devices with optimal capacity according to their needs. This education program demonstrates the effectiveness of energy literacy in improving electricity consumption habits at the household level. Therefore, simple technical understanding can boost family economic financial advantages through sustainable effective energy consumptions.

Bullying is a form of aggressive behavior commonly experienced by adolescents and has significant impacts on both physical and mental health. Schools, as primary social environments for teenagers, often become settings where bullying occurs. Several factors contribute to this behavior, particularly peer influence, family roles, and social media use. This study aimed to analyze factors related to bullying behavior among adolescents in a junior high school, including respondent characteristics, peer influence, family roles, and social media usage, as well as their relationships with bullying behavior. This research used a quantitative approach with a cross-sectional design involving 71 eighth-grade students as respondents. Data were collected using structured questionnaires and analyzed with the Chi-Square test. The results showed significant relationships between peer factors (p=0.003), family roles (p<0.001), and social media use (p=0.001) with bullying behavior. A large proportion of respondents reported high social media usage (45.1%) and low family involvement (45.1%), while more than half (53.5%) were categorized as being at risk of engaging in bullying behavior. These findings indicate that adolescents are strongly influenced by their social environment, both offline and online. Negative peer interactions and limited family supervision can increase the likelihood of bullying behavior. In conclusion, peer factors, family roles, and social media use are significantly associated with bullying among adolescents. Therefore, collaboration between families, schools, and communities is essential through psychosocial assessments, increased family involvement, and character education programs to prevent and reduce bullying behavior.

The development of e-commerce and digital financial services has changed consumer behavior, particularly among Generation Z. One emerging innovation is the Paylater service, which offers convenience and flexibility in transactions. While providing easy access, the use of Paylater also has the potential to increase consumer behavior and impulsive purchases. This study aims to analyze the role of financial literacy and lifestyle in the use of Paylater services among Generation Z through the Systematic Literature Review (SLR) method. A total of ten scientific articles published in the last five years were analyzed to examine the relationship between financial literacy, lifestyle, and Paylater usage behavior. The results show that financial literacy has an inconsistent influence and tends to act as a controlling factor, while a consumptive and hedonistic lifestyle is the dominant factor driving Paylater use. In addition, behavioral factors such as impulsive purchases and technological convenience also strengthen the tendency to use these services. This study concludes that increasing financial literacy balanced with controlling a consumptive lifestyle is very influential in encouraging the wise and sustainable use of Paylater.

Drug storage is not only carried out in health facilities but can also be done independently by the community that consumes drugs, either as an emergency supply or leftover medication from previous use. Drug storage is often done without paying attention to the condition after the packaging is opened or understanding the drug's usage limit/Beyond Use Date (BUD). The community generally only looks at the expiration date/Expired Date (ED) on the drug packaging as a reference for safe drug use, and does not understand the safe usage limit for drugs after the primary packaging is opened. The purpose of this community service is to evaluate the community's knowledge and practices regarding the implementation of BUD/ED, as well as to provide education. This community service was carried out with an educational approach involving 21 people in Rejosari Village. This activity was carried out by distributing questionnaires to the community about the knowledge and practice of BUD/ED daily, then continued with the delivery of education using posters. The results of this activity indicate that the community has good knowledge of ED and BUD, but has not yet implemented ED and BUD in the storage and use of drugs independently.

Pseudomonas aeruginosa is a Gram-negative bacterium commonly found in the environment and serves as an important indicator of microbiological contamination in cosmetic products. Its ability to survive in low nutrient conditions and its resistance to various preservatives make it a microorganism frequently found in water-based products. Contamination can occur during production, storage, and use, and has the potential to cause irritation or infection, especially in individuals with low immunity. This literature review was compiled based on data searches on PubMed, Elsevier, Google Scholar, and Scopus with inclusion criteria of original studies from 2015 to 2025 that reported the detection of P. aeruginosa in cosmetic products. The results of the review show that P. aeruginosa is not only found in new products but also in used products, mainly due to unhygienic usage practices. Although some products are declared free from contamination, monitoring of the production process and consumer education on how to use and store cosmetics are still necessary. Thus, the detection and control of P. aeruginosa are important aspects in ensuring the safety of cosmetic products on the market.

The goal of this community service program (PkM) at SMA Negeri 11 Samarinda is to increase students' enthusiasm for reading by providing them with e-books that are based on QR codes.
