Abstract
This research aims to determine the diversity of arthropods on 2 rice cultivation fields with the first land treatment planted with kenikir flower refugia and the second land without planting kenikir flower refugia. The research was conducted on May 9, 2018 to August 16, 2018 at 2 locations of rice field area with membramo variety in Sentong Village, Krejengan District, Probolinggo Regency. The research uses 2 areas of rice cultivation land with ecological engineering and without ecological engineering treatment. The ecological engineering uses kenikir flowers as a biological pest control. The data from observations of arthropod diversity was analyzed using the Shannon-Wiener (H ') formula and dominance index data was analyzed using the Simpson dominance index formula (C). The data analyzed using non parametric test statistics spsss 15.0 to distinguish between treatments. The results showed that the Diversity Index in the ecological engineering area of kenikir flowers was 1.89, the Domination Index was 0.168 and for dry grain weights were 43.88. On land without ecological engineering the Diversity Index is 1.73, the Domination Index is 0.179 and for dry grain weight is 30.96.
