The discovery of internet information, performed business transaction, etc. The occurence of social media since the 1990s has developed a new function of each other virtually. Unfortunately, social media is suspected to cause phubbing behavior among internet users. A previous study has stated that the 'like' and 'love' responses in social media posts may cause a social media addiction in the users' everyday life that can interfere with their daily activities. In this article, we explain briefly a review from neuroscience perspective on the emergence of addictive behavior in the use of social media in daily life.

BACKGROUND: Exposure to environmental enrichment has a positive effect on brain function, including improved cognition. Environmental enrichment has many aspects, including social interactions, object stimulations, and physical activities. Exercise and environmental enrichment can be considered to improve cognitive function with different underlying mechanisms. This study aims to compare the effects of environmental enrichment and aerobic exercise at both synaptic and whole-organism levels using synapyophysin as a measure of synaptic physiology and spatial memory as a measure of cognitive function.METHODS: A six-week in vivo experimental study on 15, 6-month old male Wistar rats randomly divided into three groups (n=5): aerobic group (A), enriched environment group (EE), and enriched with an aerobic or combined group (EEA). All rats were tested four times in the Water-E maze (WEM) task at weeks 0, 2, 4, and 6 of the study. We used immunohistochemistry to determine the synaptophysin expression in hippocampal CA1 region.RESULTS: Based on synaptophysin immunostaining, there were higher optical density scores for synaptophysin in hippocampal CA1 region following EEA, but there were no statistically significant differences between groups (ANOVA test, p>0.05). The spatial memory test showed there were significantly reduced travel time and total errors from the 2nd and 4th weeks in the EEA group, respectively (p<0.05).CONCLUSION: The combination of enriched environment and aerobic exercise seems to rapidly improve spatial memory and enhances the presynaptic protein, synaptophysin in hippocampal CA1 region.KEYWORDS: aerobic exercise, environmental enrichment, spatial memory, synaptophysin, Water-E maze

Pornography content is becoming an increasingly serious problem in Indonesia, where it is suspected that around 97% of 1,600 children and adolescents have been exposed to pornography. Various efforts prevalence of pornography content, such as by blocking porn known that the exposure of massive and periodic pornography content to children and adolescents can result in adverse e EEG (Edison, RE., et al) and fMRI (Prawiroharjo, P., et al) have reported changes in the brain activity of children and adolescents who were suspected as having addiction to pornography content. Intere among the subjects. This article discusses the phenomenon from the perspectives of psychology and neuroscience.

Tingkat pengetahuan guru olahraga tentang gizi yang tepat bagi atlet merupakan salah satu aspek penting yang mempengaruhi prestasi atlet usia sekolah dasar. Oleh sebab itu, diperlukan kegiatan pengabdian masyarakat sebagai salah satu upaya untuk meningkatkan pengetahuan guru olahraga mengenai gizi atlet sehingga mampu memberikan prestasi olahraga yang optimal. Kegiatan pengabdian dilaksanakan pada tanggal 9 Agustus 2022 di SDN 149 Seluma Air Kemuning Kecamatan Sukaraja Kabupaten Seluma Bengkulu. Sebanyak 25 guru olahraga menjadi mitra pengabdian. Pelaksanaan pengabdian menggunakan metode Community Based Participatory Research dengan langkah-langkah yang diterapkan adalah membangun komitmen, perencanaan, pengumpulan informasi, aksi, monitoring dan evaluasi. Teknik pengumpulan data menggunakan tes tertulis. Hasil analisis diketahui bahwa nilai rerata sebelum dilaksanakan pengabdian adalah sebesar 59,2 sedangkan nilai rerata setelah dilaksanakan pengabdian adalah sebesar 76,8. Hasil analisis uji-t menggunakan SPSS diketahui bahwa nilai Sig.(2-tailed) sebesar .000 < 0.05 sehingga dapat disimpulkan bahwa kegiatan pengabdian yang dilakukan memberikan pengaruh terhadap tingkat pengetahuan guru olahraga mengenai gizi atlet.The level of knowledge of sports teachers about proper nutrition for athletes is one of the main aspects that affect the achievement of elementary school-age athletes. Therefore, community service activities are needed to increase sports teachers' knowledge about athlete nutrition so that they can provide optimal sports achievements. The service activity was carried out on August 9, 2022, at SDN 149 Seluma Air Kemuning, Sukaraja District, Seluma Regency Bengkulu. As many as 25 sports teachers became service partners. The service implementation uses the Community Based Participatory Research method with the steps applied: building commitment, planning, gathering information, taking action, monitoring and evaluating. The data collection technique used a written test. The results of the analysis showed that the average value before the service was carried out was 59.2, while the average value after the service was carried out was 76.8. The results of the t-test analysis using SPSS showed that the value of Sig. (2-tailed) was .000 < 0.05, so the service activities carried out influence the level of knowledge of sports teachers regarding athlete nutrition.

The COVID-19 pandemic is a major challenge to Indonesia’s to improve public health. Vaccination has been increased in the fight against COVID-19. The education goal is to raise awareness about the advantages of COVID-19 vaccination. Ten teachers and education staff are taking part in this community service project. This activity began with completing a pre-test questionnaire about the advantages of the COVID-19 vaccination, followed by counseling from expertise and completing the post-test questionnaire. The results of the questionnaire evaluation after counseling improved by 95%, indicating a better understanding of the advantages of COVID-19 vaccination. Throughout the outreach activities, all participants were enthusiastic about the material presented while also discussing the hoaxes that were currently circulating in the community.
