Abstract

Early detection of developmental disorders in early childhood is a strategic step in supporting optimal child development. This study aims to describe the implementation of early detection of developmental disorders at RA Darul Ihsan NW Toya. This study used a descriptive qualitative approach with data collection techniques through observation and in-depth interviews with teachers, parents, and health centre staff. The results indicate that teachers have conducted structured observations in monitoring children's growth and development. However, parental participation remains limited and has not been optimally integrated. Collaboration with the health centre is carried out through health education and examinations, although it is not yet systematic. The conclusion of this study emphasizes the importance of collaboration between educational institutions, families, and health services. Practical implications include the need to enhance teachers' capacity, educate parents, and establish a sustainable cooperation system. It is recommended to develop a community-based early detection programme integrated into early childhood education.

Abstract

Currently, the antibacterial research is increasingly promoted primarily from natural materials, due to the increasing number of pathogenic bacteria that have been resistant to existing antibiotics. One of the pathogenic bacteria that has been much resistant to antibiotics is Staphylococcus aureus. Rosella calyx (Hibiscus sabdariffa L.) and chitosan are known to have antibacterial activity. The aim of this study to find out the antibacterial synergy of the roselle calyx extract and chitosan against. S.aureus ATCC 33592. Rosella calyx was extracted by maceration using 80 % ethanol, while chitosan is obtained from deasetilation chitin of shrimp husk. Test antibacterial synergism using checkboard assay method by calculating the minimum inhibitory concentration (MIC) using microdilution assay. The results showed minimum inhibitory concentration (MIC) value of roselle calyx extract and chitosan were 1250 ppm and 50 ppm, respectively. MIC value of rosella calyx extract in the presence of chitosan was 625 ppm, while the value of MIC chitosan in the presence of rosella calyx extract was < 0.19 ppm. Fractional Inhibition Concentration Index (FICI) was < 0.5 which concluded that the combination of roselle calyx extract with chitosan has a synergistic antibacterial effect on S.aureus ATCC 33592.
