The Diversity Of The People's Coffee In The Sekarkijang Area (Besuki And Lumajang) As A Source For Learning Biology Of High School

This study aims to identify and analyze the diversity of morphological characters from the collection of Robusta, Arabica, and Liberica coffee types in Bondowoso Regency and their use as a source of high school biology learning in the form of encyclopedias. The research was conducted in 6 sub-districts in Bondowoso Regency. Determining the location of research using Purposive sampling and interview techniques using Snowball sampling. The experiment was carried out by morphological characterization of 14 Robusta clones, 13 Arabica varieties, and 2 Liberica varietes using a descriptor list that was modified for coffee plants. Qualitative data were analyzed using triangulation and tabulated based on morphological tables of coffee plants. The morphological identification results Robusta, Arabica, and Liberica coffee plants showed that there were many differences, especially on the morphology of the leaves, fruits, and seeds.
