Keanekaragaman Vegetasi pada Sistem Agroforestri Berbasis Kopi di Desa Rowosari Kecamatan Sumberjambe Kabupaten Jember

Abstract

The coffee-based agroforestry system is one of the agroforestry systems that has a varietyof plants and support ecosystem services. This study aims to determine the diversity of vegetation in coffee-based agroforestry systems in Rowosari Village, Sumberjambe District, Jember Regency. The research was conducted on simple agroforestry and complex agroforestry using purposive sampling to collect vegetation data using the single square method. The results showed that the highest importance value index was for undergrowth, namely Oplismenus hirtellus in complex agroforestry lands (INP = 36,607%) and simple agroforestry lands (INP = 36,301%). The highest importance value index was for trees in complex agroforestry, namely Coffea canephora (INP = 101,158%) and in simple agroforestry, namely Pinus merkusii (INP = 107,104%) and Coffea canephora (INP = 105,832%). The index of species diversity, evenness, and species richness of the undergrowth had the highest value.
