ABSTRACT
To increase potato seed production, special treatment is needed, including the application of Gandasil D leaf fertilizer and coffee skin compost on potato plants. This study aims to determine the effectiveness of the dosage of Gandasil D application and coffee skin compost to increase the potato yield. The experiment was conducted using factorial randomized block design (RBD) and repeated 3 times. Factor 1, Gandasil D consists of 3 levels, namely D0 (control), D1 (1 gram / liter), and D2 (2 gram / liter). Factor 2, coffee skin compost consists of 3 levels, namely K0 (control), K1 (40 gram / plant) and K2 (50 gram / plant). Each treatment was repeated by 3 times. This research was conducted on Jampit Viilage, Ijen district, Bondowoso, located on 1,050-1500 meters from the sea level. The results showed that the application of Gandasil D had a very significant effect on the growth of height, the number tubers and the weight of tuber crops. The application of coffee skin compost has a very significant effect (**) with the number of tubers as much as 7.37 tubers per plant in the number of tubers with 50 grams of coffee compost / plant.
