Murraya koenigii (L.) Spreng is often known as Temurui or Curry as a local name in Indonesia, and has long been used in medicine and has as a potential as a multi-medicinal plant. Temurui as a producer of bioactivity has the antioxidant properties. This is due to the presence of metabolite compounds contained in the leaves of the Temurui plant. Leaves are organs that are always growing where chemical components such as chlorophyll in the leaves will also develop thereby affecting leaf metabolism in plants. This study aims to determine the contens of chlorophyll, contens of antioxidants and metabolite compounds in Temurui leaves at the level of leaf development. Different leaf extractions are also used to measure the antioxidant, chlorophyll content and metabolite compounds found in Temurui leaves. The research results obtained on young, and old Temurui leaves obtained a total of 3 groups of dominant compounds, terpenoids, organic acids and esters, and mature leaves not find ester compound. The level of leaf development affects the contents of antioxidants and chlorophyll contents. Chlorophyll content in mature leaves was 44.60ug/ml, young leaves were 41.28ug/ml and old leaves were 30.27ug/ml while antioxidant contents in young leaves were 8.949ppm, mature leaves were 8.85ppm and old leaves were 8.429ppm.

Covid 19 has become a global epidemic, including in Indonesia. The changing era, which is now wholly digitalized, makes it easier for humans to receive, access and disseminate information about the pandemic. The amount of data spread does not rule out the possibility of circulating news containing hoaxes, and it is even more dangerous if the report includes elements of provocation. Therefore, digital literacy skills are needed for the community, especially for students majoring in KPI IAIN Pekalongan. As KPI students, we must be wise in processing information. For this reason, the authors researched the digital literacy skills of students majoring in KPI IAIN Pekalongan regarding the COVID -19 infodemic with a qualitative method using phenomenological theory. After conducting observations and interviews, from the results of the author's analysis, it was stated that KPI IAIN Pekalongan students were familiar with digital literacy regarding news about Covid 19. However, some still wanted to share new news without the source's credibility. This is due to the lack of digital literacy, especially in disseminating information related to the issues of the Covid 19 pandemic.
