Ethnoscience is one of the activities in transforming indigenous science into scientific science that can be implemented in the biology learning process. The implementation of the ethnoscience stage in biology learning can improve students' critical thinking skills, which is the aim of this research. This research is experimental research using a pretest-posttest control group design. The research population consisted of 36 students. The sample selection used a random sampling technique consisting of 2 classes (experimental and control), each class consisting of 18 students.

The district's traditional drink, kawa drink, made from dried coffee leaves, is used by the Kerinci people. The primary purpose of this investigation is to use ethnoscientific research to turn common knowledge about the techniques used in processing kawa drinks into scientific knowledge. This study employs a qualitative, ethnoscientific phenomenological methodology that includes observation, which involves learning where to gather the coffee leaves that will be used to make kawa drinks in the step one.

Online learning is an alternative learning system, especially when face-to-face learning cannot be held. This study aims to analyse the perceptions of high school teachers in the city of Sungaipuh about the online learning system and find out the problems of teachers in implementing it. This research is quantitative research with a descriptive approach. The population of this study were high school teachers and equivalent schools in Sungaipuh with a sample of 182 people. Data was collected through surveys using open and closed questionnaires.

The increasing resistance of pathogenic bacteria to antimicrobials requires the discovery of new antibiotics. Angsana plant or Lansano (Pterocarpus indicus Willd) is one of the medicinal plants in West Sumatra. Angsana has the potential to have endophytic bacteria capable of producing antibiotic compounds like its host. The endophytic bacterial isolates of Angsana can inhibit the growth of S. aureus and E. coli bacteria. This study aims to determine the genetic characteristics of the endophytic bacteria of Angsana leaves that produce antibiotic compounds through phylogenetic tree analysis.

Increasing cases of antibiotic resistance encourage researchers to find new bioactive compounds. The source of the newly developed antibiotics is utilizing endophytic bacteria. BA1 isolate is an endophytic bacterium from Lansano plant (Pterocarpus indicus Willd) which has high antimicrobial activity. Antibiotic compounds are produced through a fermentation process. The purpose of this study was to optimize the fermentation conditions of endophytic bacteria Lansano isolate BA1 in producing antibiotic compounds. Optimization of the fermentation time was carried out for 72 hours.

This study aims to reconstruct the community's original knowledge in the process of making potato dodol into scientific knowledge according to the halal criteria of a product determined by the halal product guarantee system. The research method used is descriptive qualitative based on ethnoscience with the scope of examination including document analysis, interviews and documentation. Data collection is done directly to respondents (business actors) by purposive sampling.
