Aging is a natural process in human life and is triggered by the presence of free radicals (ROS). The use of antioxidants from natural ingredients is one of the breakthroughs to overcome aging and counteract the harmful effects caused by the free radicals. This study aimed to determine and compare the antioxidant activity of H2O2 scavenging and hyaluronidase inhibition of red dragon fruit peel extract (DFPE) and kaempferol-3-o-rutinoside (KOR) compounds. Dragon fruit peel extract (DFPE) is obtained through extraction by maceration method using 70% ethanol solvent. The design of this study included antioxidant and anti-aging activity assay of EKBN and KOR at the series concentration of 15.63; 31.25; 62.50; 125; 250; 500 µg/mL through H2O2 scavenging, as well as the DFPE and KOR hyaluronidase inhibition assay at the series concentration of 5.21; 10.42; 20.83; 41.7; 83.33; 166.67 µg/mL. EKBN shows that the average activity of H2O2 scavenging is lower than KOR. In addition, the IC50 values of KOR for H2O2 scavenging is lower (351.46±2.30ug/mL) than DFPE (409.64±23.17ug/mL). While, KOR also has higher values of inhibitory activity than of the DFPE. However, the IC50 value of KOR for hyaluronidase inhibition activity was 84.07±10.46µg/mL, equivalent to the IC50 value of DFPE (85.32±10.24µg/mL). The presence of antioxidant and anti-aging activity in the EKBN is probably caused by betalain and the KOR compound itself contained in red dragon fruit. The results of the paired-samples T-test on antioxidant activity and anti-aging of DFPE and KOR showed non-significant difference. Thus, DFPE has an equivalent antioxidant and anti-aging through H2O2 scavenging and hyaluronidase activity as possessed by the KOR compound.

Background: The effectivity role of community mental health worker (CMHWs) has several important gaps in the service provision at the community level. This study aimed to explain community mental health workers' effectivity role for the rehabilitation of mental health illness. Methods: A systematic review searched five electronic databases (Scopus, PubMed, ScienceDirect, CINAHL, and ProQuest) for previous studies published between 2015 and 2020. The Centre for Review and Dissemination and the Joanna Briggs Institute Guideline used to assess quality and Prisma checklist guided this review. Title, abstract, full-text and methodology were assessed for the eligibility of the studies. Data tabulation and narrative analysis of study findings were performed. Results: We found 10 studies which discuss the role of community health worker and the effectivity were community health workers as a primary care giver, counselor, partner for mental health patient, the effectiveness also produce government policy in community health worker existence, and improving self-advocacy and patient outcomes. Conclusion:The role of CMHWs in mental health is to become caregiver, partner, support, efficacy and improve the patients' condition. Based on the finding, the suggestion was the part of CMHWs becomes important to increase the health condition of mental patients during rehabilitation.

Wildlife trade for consumption needs is found in various regions in Indonesia, one of which is in North Sulawesi Province. This animal trade spreads in traditional markets, including the Beriman Market in Tomohon which is also a domestic and foreign tourist destination, Langowan and Kawangkoan Markets in Kab. Minahasa. Karombassan and Bersehati Market in Manado City. Even the trade in wild animal meat has now entered modern markets in Manado City, which is the capital of North Sulawesi Province. This development of course threatens the preservation of biodiversity, especially endemic species. This study aims to determine the types of wildlife traded in North Sulawesi both in traditional and modern markets, to compare the price of wild animal meat in traditional and modern markets in North Sulawesi, and to determine the conservation status of traded wildlife species. There are 8 types of wild animals traded in traditional markets and 5 species in modern markets. The price of wild animal meat in the modern market is higher than in the traditional market. There was one endemic species that was traded, and 2 species that were listed in Appendix II of CITES.

Indonesia memiliki budaya yang sangat banyak dan beragam. Namun kenyataannya kurang adanya kesadaran masyarakat untuk melindungi dan melestarikannya. Etnomatematika memiliki peran penting dalam upaya mengenalkan budaya kepada generasi muda sekaligus mempelajari konsep matematika. Tujuan dari penelitian ini adalah untuk mengeksplorasi konsep matematika pada pakaian adat Lampung. Metode yang digunakan dalam penelitian ini adalah metode penelitian kualitatif melalui studi literatur. Berdasarkan hasil kajian dan eksplorasi terhadap konsep matematika diperoleh bahwa pakaian adat Lampung mengandung konsep matematika antara lain bentuk geometri, konsep bilangan, sudut dan transformasi geometri. Dengan demikian, diharapkan hasil penelitian ini dapat digunakan sebagai bahan rujukan pada materi matematika sekolah. Keywords: Etnomatematika, Konsep Matematika, Geometri, Bilangan, Sudut.

The main objective of this research is to prove whether the digital storytelling enhances and improve students writing competency. The study uses classroom action research (CAR). The data in this study are quantitative and qualitative data. The quantitative data will be collected by using the essay test. The qualitative data will be collected by using observation, field notes, and questionnaire. The score of students’ writing descriptive text kept increasing from pre-test until post-test. It was proved by the data which showed that the mean of the students’ score in post-test II is 86.6 (92.75%) was higher than the post-test I is 72.2 (68.75%), and also higher than the pre-test 54.8 (25%). The response of student in using digital storytelling in the agree category, it can be seen from the 15 students who passed the KKM (70) and 1 student still low of KKM. The class percentages of post-test II show improvements from the previous test; the improvement is 67.75%. The frequencies of item agree appear 110 times or (52.88%). Furthermore, it can be concluded that Digital Storytelling is effective and useful to be used in teaching writing skill, especially in Descriptive Text.
