Kaongkeongkea coffee is one of Indonesia's 50-year-old germplasm coffees. However, it has low production and productivity because its cultivation system has never been treated. The purpose of this study was to analyze the response of pruning and the use of goat manure doses to kaongkeongkea coffee yields and to analyze the interaction between pruning treatment and goat manure dosage. This research was carried out from December 2021 to August 2022 in Kaongkeongkea Village, Buton Regency, Southeast Sulawesi, at an altitude of 540 meters above sea level. This research was conducted in the form of a 2-factor factorial experiment. Based on a completely randomized design pattern. The first factor is pruning maintenance and production, which consists of two levels, namely, no pruning (P1) and pruning (P2). While the second factor is the dose of goat manure which consists of four levels, namely without goat manure (K1), goat manure 5 kg per plant (K2), goat manure 10 kg per plant (K3) and goat manure 15 kg per plant. plants (K4). Each treatment was repeated three times and used four sample plants, so there were 96 sample plants. Pruning on 50-year-old Kaongkeongkea coffee plants can increase the number of fresh coffee berries per cluster, the number of stumps per branch, the weight of the stump per branch, the weight of the fresh coffee cherries per branch and the weight of fresh coffee per plant. The dose of goat manure from a dose of 0 kg to 15 kg did not increase the yield of coffee plants, and there was no interaction between pruning and the dose of goat manure.
