This study entitled the effect of giving various orange peels as a repelence of rice lice (Sitophillus
oryzae L.) and its contribution to pest and disease material in plants in class VIII. This study aims to
determine the effectiveness of various orange peels as a repelence of what type of rice lice and
orange skin is most effectively used as a repelence of rice lice. The type of research used in this
study is quantitative descriptive research (where the data collection process uses statistical analysis)
and the experimental method. The data obtained were analyzed statistically using Analysis of
Varience (ANOVA). Analysis of the variance of the treatment effects for a complete randomized
design (CRD) was carried out according to the F test. Based on the results of the research, each
treatment was significantly different from the control. The highest percentage of rejection was
found in the treatment of lime peel, which amounted to 56.25 at 76 hours and the lowest percentage
was found in the treatment of sunkist orange peel ie 27.5 at 76 hours. Hypothesis testing results for
F count treatment (19> 1.79) and F count Factor A (40> 2.99) and F count on Factor B (102> 3.20),
this states that slices of various orange peels (Citrus sp.) very significant effect to reject rice
infestation (Sitophillus oryzae L.), so that it is stated that H1 is accepted and H0 is rejected. Thus it
can be concluded that various citrus coolies are effective as repelensi rice mites (Sitophillus oryzae
