Abstract Infectious diseases are common problems in most countries. Streptococcus pyogenes is the infectious agent that causes diseases such as pharyngitis, impetigo, toxic shock syndrome, and necrotizing fasciitis. Tembelek (Lantana camara) is a wild plant that can easily be found in every ecosystem in Indonesia whether in nature or settlements and known as a plant that has an antibacterial effect but the knowledge about its potential against Streptococcus pyogenes in this past five years remain scant. The aim of this study was to determine the potentiality of Lantana camara leaves and flowers extract against Streptococcus pyogenes. In this experimental study, in vitro using Post-test Only Control Group Designed, has been done and confirmed by the Indonesian Institute of Sciences. Lantana camara leaves and flowers extracts were obtained by maceration using ethanol. The extracts were diluted into eight concentrations and their antibacterial activity against Streptococcus pyogenes was tested using the Kirby-Bauer disc then proceeded Minimum Inhibitory Concentration (MIC) test and phytochemical assay. The data processed using SPSS software version 22. The results showed that flowers extract had the most significant inhibition zone (11.85 ± 0.119 mm) compared with the leaves extract (9.54 ± 0.07 mm) at the highest tested concentration was 640 mg/ml. The MIC of both extracts was 250 mg/ml. Flavonoids, phenolic, steroids, and saponins were found in both extracts whereas, alkaloid was found only in flowers extract. In conclusion, the Tembelek plant has an antibacterial effect against Streptococcus pyogenes. Future study is needed related to its mechanism of antibacterial effect.

Abstract A preliminary study showed that most health workers in primary health care (PHC) claimed that they need a refreshing course because of their lack of updated knowledge and skill. This study enrolled 27 primary healthcare workers recruited from the PHC. The intervention used were classic lectures and workshops. The knowledge was evaluated using a paper-based test and practice, while the skill was evaluated using a practice test. Multiple questions (pre-test and post-test) based on current emergency management for pediatric were used for paper-based evaluation. Semi-structured interviews were conducted to confirm the subject's perspective on the intervention. A paired t-test was used for evaluating the pre- and post-test results, which was confirmed by a triangulation approach. There was a significant difference between the pre- and post-test results (p<0.001), and 8 of 10 subjects can demonstrate the procedure learned correctly after the intervention. A total of 14 interviewed subjects stated great effectiveness of the intervention, with several limitations on applicability in daily clinical practice. Classic lecture and workshop as an intervention in health education effectively increase health workers' knowledge and skill in PHC. This study might help other rural areas PHC apply the same method so the professionalism and quality of health workers in PHC providers can be maintained.Keywords : primary health care, classic lecture; workshop; knowledge; skillCorrespondence : rickyindraalfaray@gmail.com
