grown in rice fields interferes with rice plants since they compete with crops for
nutrients. This study aimed to determine the structural analysis of weed
composition in the rice fields in Mentayan Village, Bantan District, Bengkalis
Regency. The experiment used quadratic method in two areas (area 1 and area
2). There were 10 plots per area with size of each plot was 5 m x 5 m and space
between plots was 20 meters. The research results found 20 species from 10
families with a total of 839 individuals. The highest dominant value was 46.32 at
area 1 and the lowest dominance was 0.7 at plot 2. The highest importance value
index in area 1 and area 2 was Imperata cylindrica species with a respective
