Abstract

Hypothenemus hampei (Ferrari) (Coleoptera: Scolytidae) or Coffee Berry Borer (CBB) is the most destructive major pest that causes quantitative and qualitative losses in Arabica coffee. The research aimed to calculate population, attack H. hampei, coffee yield losses, the measure distribution pattern of H. hampei on various Gayo arabica coffee varieties, and the analyze estimated decrease in the production of coffee based on population and attack H. hampei in Gayo arabica coffee. The location chosen as a place of observation and sampling is a smallholder coffee plantation with variations in elevation. Each area is determined by two points of observation and sampling locations. At each sampling location, 80 ripe or red coffees were taken, 80 dark or yellow coffees, and 80 young or green coffees (24 pieces per four branches per tree). The results showed that the population and attack of CBB pests on Gayo 3 varieties are relatively high compared to Gayo 1 and Gayo 2 varieties. The distribution pattern of CBB on all varieties of Gayo Arabica coffee showed an aggregated distribution based on population and attack. The decrease in arabica coffee production has the potential to occur on a variety Gayo 3.

Abstract

Coffee beans take a longer time to germinate and need a method to solve it. Plant Growth Promoting Rhizobacteria (PGPR) found in plant roots can produce phytohormones that can break the dormancy of the seeds and stimulate the growth of Arabica coffee beans. This study aims to study on the effect of PGPR from the roots of yellow and green bamboo to the growth of arabica coffee seeds. The experiment used a randomized block design with the first factor being the type of bamboo roots, namely yellow bamboo and green bamboo. The second factor was the concentration of PGPR which consisted of 4 (four) levels of PGPR concentration in water that are control (no treatment, 10, 20, and 30 ml.L-1 water).The results showed that the application of PGPR from bamboo roots had a significant effect on plant height, the number of leaves, fresh weight of crown plants, leaf fresh weight, shoot dry weight, and leaf dry weight of arabica coffee seeds. The application of PGPR from yellow bamboo roots with a concentration of 30 ml.L-1 gave a significantly effect on the growth of arabica coffee seeds. PGPR with a concentration of 30 ml.L-1 is suitable due to accelerating the growth of Arabica coffee seeds so that it becomes a solution in Arabica coffee seeds development.
