ABSTRACT
Cockroach is one of the insects that acts as a disease vector generally found in homes and buildings including restaurants or food stalls. Cockroaches can contaminate human food by becoming the agents of various digestive-related diseases such as diarrhea, typhoid fever, dysentery, hepatitis A virus, polio and cholera. Coffee is cultivated in Indonesia which in general consists of two types namely Arabica coffee and Robusta coffee. Arabica coffee is coffee which has a better flavor than Robusta coffee since Robusta coffee tastes bitterer, less acidic and contains higher caffeine than Arabica coffee. This study aims to determine the effect of coffee grounds as a natural insecticide for cockroach (Periplaneta americana) repellent 2019. This was an experimental study conducted in the laboratory and workshop of environmental health department in May 2019. The objects of this study were cockroach (Periplaneta americana) and coffee grounds to observe which dose is the best for cockroach repellent, and analyzes the people's acceptance of the coffee grounds products produced. Test results on the effectiveness of coffee grounds as a cockroach (Periplaneta americana) repellent at a dose of 10 gr, 15 gr and 20 gr for repetition of the first, second and third, showed that the rejection of cockroaches (Periplaneta americana) in large quantities was achieved at a dose of 15 grams of coffee groundsnamely 25 cockroaches with a mean of 8.3. The results of two-way ANOVA test showed that there was no significant difference on the effectiveness of coffee grounds as a cockroach (Periplaneta americana) repellent. The durationvariable obtained a p value of 0.539>0.05 which indicated that there was no difference. Meanwhile, the dose variable obtained a p value 0.074>0 05 which indicated that there was no difference and the interaction between duration and dose (duration * dose) was 1.522 with a probability of 0.214>0.05.Thus, it can be said that there was no difference between the duration and the number of cockroaches that refused. It can be concluded that there was no effect of the dose of 10 grams of coffee grounds on cockroach (Periplaneta americana) repellent activity which obtained 16 cockroaches with a mean of 5.3. Furthermore, there was no effect of the dose of 15 grams of coffee grounds on cockroach (Periplaneta americana) repellent activity whichobtained 25 cockroaches with a mean of 8.3. Further researchers are expected to be able to conduct a study oncoffee grounds with more varied doses.
