    This study was done to determine the effects of steeping temperature and storage period on the bioactive contents plus antioxidant and antidiabetic activities of Pluchea leaf infusion. The research used a randomized block design with two factors, i.e. steeping temperature (T) and storage period (B). The Pluchea leaf blades were exposed to four steeping temperatures of 60 (T1), 70 (T2), 80 (T3), and 95 (T4) °C with the storage period of 0 (B1) and 5 (B2) yr – resulting in eight treatment combinations (T1B1, T1B2, T2B1, T2B2, T3B1, T3B2, T4B1, T4B2). Statistical analysis using a paired t-test at α ≤ 0.05 showed that treatments significantly affected the bioactive contents [total phenol (TPC), total tannin (TTC), and total flavonoid (TFC)], antioxidant [DPPH scavenging activity (DPPH) and ferric reducing antioxidant power (FRAP)] potential and antidiabetic [α-amylase (AA) and α-glucosidase (GA) inhibition] properties of the Pluchea leaf infusion. TPC, TTC, DPPH, and FRAP significantly increased for the storage period and the steeping temperatures. Then, TFC decreased during the storage period but significantly increased at higher steeping temperatures. The AA and GA of Pluchea leaf infusion increased until 70 °C of the steeping temperature but decreased until 95 °C. The DPPH and FRAP of the Pluchea leaf infusion were strongly and positively correlated with TPC and TTC. The GA and AA of Pluchea leaf infusion were not influenced by the TPC and TTC but were weakly and positively correlated with TFC. The antioxidant activity of the Pluchea leaf infusion was inversely proportional to the antidiabetic activity. The simple phenolic compounds derived from Pluchea leaf infusion at different steeping temperatures and storage included gallic acid, kaempferol, myricetin, (+)-catechin, quercetin, 3,4-di-O-caffeoylquinic acid, 3,5- di-O-caffeoylquinic acid, and 4,5-di-O-caffeoylquinic acid

    Safety behavior has an important role to support the physical and psychological health of individuals during a pandemic as well as in adapting to a new normal life order. This study aims to identify patterns of safety behavior displayed by the community, especially workers in the new normal. The variable in this study, namely safety behavior with descriptive quantitative research methods. The survey was used as a data collection method with 103 subjects as the research subjects working in normal times. The results showed that safety behavior was in the High and Very High categories where the subject was able to display safety behavior when interacting in public places, workplaces, and in the home environment. Subjects not only demonstrate compliance with safety regulations and procedures, but also participate in encouraging the creation of a safe work environment to avoid the spread of the corona virus when entering the new normal. Workers should maintain safety behavior in their daily life, and the results of this study provide information for industry or companies to determine follow-up plans and strategies for managing occupational safety and health in the new normal
