Abstract

The storage period of stored rice will experience damage and shrinkage in quantity and quality. One of the causes of the decline in the quantity and quality of stored crops is the attack of the warehouse pest Sitophilus oryzae (rice lice). Sitophilus oryzae pest control can be done by using clove leaves. This study aimed to determine the effectiveness of clove leaf (Syzygium aromaticum L.) in controlling the pest Sitophilus oryzae and the leaf weight of clove (Syzygium aromaticum L.), which was effective in controlling the pest Sitophilus oryzae. This study used a Completely Randomized Design (CRD) with five treatments and was repeated three times and analyzed one way ANOVA 95% if the BNT test followed a difference. This study showed that administering clove leaves with a weight of 15 g, 20 g, 25 g, and 30 g can control the pest Sitophilus oryzae in rice. This can be seen in the average mortality of Sitophilus oryzae on day 4. The weight of 15 g is 36,67%, the weight of 20 g is 48,33%, the weight of 25 g is 60,00%, and the weight of 30 g is 78,33%. ANOVA results showed that clove leaf treatment significantly affected the mortality rate of imago Sitophilus oryzae. This is indicated by the p-value> 0,05. In addition, from the results of the BNT test, it was found that the doses of 15 g, 20 g, 25 g, and 30 g showed an effect on the mortality of imago Sitophilus oryzae. This study concludes that clove leaf can control the pest Sitophilus oryzae on rice; the effective weight of clove leaves in controlling the pest Sitophilus oryzae on rice was 30 g, able to kill as much as 78,33%.
