Abstract

This study aims to obtain the distribution of weed diversity and the level of weed dominance in coffee plantations in Tanggamus Regency. This study uses a descriptive method, through the survey stage. Randomized block design (RBD) with 5 repetitions at 4 different altitude treatment levels, the treatments in this study were as follows: P1 500 - 600 masl, P2 601 - 700 masl, P3 701 - 800 masl and P4 801 - 900 masl. Each replication was examined at 5 scattered area points. After obtaining the required number of sample plots, a vegetation analysis was carried out. Each vegetation analysis was determined: weed species, weed density, weed frequency, weed dominance (SDR) and weed dry weight. Different environmental conditions affect the diversity and dominance of weeds such as the results listed with the status of "MEDIUM" on the weed diversity index with a diversity index value of 2.29 - 2.31 while the weed dominance conditions look fluctuating, the higher a place that is used as land. In coffee plantations, weeds of broad leaf type dominate, among others, consisting of several families of Cyperaceae, Poaceae, Asteraceae and Acanthaceae.
