Prolonged physical exercise has the risk of increasing free radicals which will affect the breakdown of red blood cells and promote the risk of decreased hemoglobin. Adolescent female athletes have a risk of decreasing hemoglobin due to menstruation. This situation can get worse if the athletes have iron defi-ciency or anemia as the result of poor diet choice. Increased radicals and anemia affect the amount of oxygen carried to the tissues and the maximum volume of oxygen an individual can use to produce energy (VO2 max). Beets have benefits for athlete's performance and have been developed into an instant drink. The purpose of this study was to determine the effect of an instant FeSO4 fortified beet juice (BeeFe juice) in overcoming anemia on female adolescent athletes. This research using an experimental study with controlled trial pre-posttest design. Twenty-nine adolescent female athletes, aged 13-19 years, were divided into two groups. Fe tablet supplementation (containing Fe 60 mg) was given to 15 athletes in the control group and BeeFe juice (containing Fe 17 mg) was given to 14 athletes in the treatment group du-ring the luteal and menstruation phase (±14 days). Hemoglobin levels, Malondialdehyde (MDA) and maxi-mal oxygen volume (VO2 max) were examined before and after the intervention. Data were analyzed using paired t-test and independent t-test IBM SPSS version 22. This research has obtained Ethical Appro-val with number KE/FK/0633/EC/2018 from the Ethical Commission of FKKMK UGM. The results showed no significant difference between the group given Fe tablets and the group given BeeFe juice on hemo-globin levels (P>0.05), MDA levels (P>0.05), and VO2 max levels (P>0.05) in the menstrual and luteal phases of menstruation. It can be concluded that BeeFe juice has the same effectiveness as commercial Fe tablets. BeeFe juice can be an alternative food ingredient in iron supplementation.

Indigenous populations experience a risk of socio-economic marginalization in health emergency, including COVID-19. Public service announcements (PSA) are promotional materials that address problems in an attempt to increase public awareness. North Kalimantan is one of the frontier, outermost, and least developed regions in Indonesia with 11 regional languages spoken. One of the districts with inadequate human resources in the area is Nunukan regency. The present study sought to understand how one group of people in Nunukan Regency reactions, interests, and impressions with the COVID-19 information found in Bugis and Toraja version of audio PSAs released by Health Empowerment and Education Project (HEUProject). The study belongs to qualitative research and used purposive sampling with seven participants from two sub-district in Nunukan Regency. The data is analyzed qualitative-thematically which is further interpreted and presented  in the form of a description. Additionally, to see the variety of participants’ answers information transmission through PSAs, we analyzed the data using Tableau software 2020 version and presented the relative frequency of words with visual infographic. The study findings of the participants' immediate reactions were following the advice on the PSAs audio, for instance to keep the physical distance and washing their hands frequently. The most participants in this study have the willingness to hear, to understand, and also feel interested with the useful content in audio format that apparently improves their awareness of COVID-19 information. Overall, it is immediately apparent that the language, transmission of message, and information found in the HEUProject’s COVID-19 educational PSA were understood and engaged by participants in a way that it reflects on the pandemic situation. Our study supports the national usage of disease prevention with this type of media approach that could be used in public places in the future that may minimize the language divide.
