Abstract

Kopi Liberika merupakan tanaman kopi yang adaptif terhadap kekeringan dan lahan gambut yang selama ini belum banyak dimanfaatkan secara optimal. Penelitian ini bertujuan untuk mengetahui pengaruh konsentrasi IBA dan bahan tanam serta interaksinya terhadap pertumbuhan stek kopi liberika. Penelitian dilaksanakan di Pusat Penelitian Kopi dan Kakao Indonesia (PPKKI) pada bulan Oktober 2014 sampai Februari 2015. Penelitian dilaksanakan menggunakan rancangan acak kelompok lengkap faktorial dua faktor yaitu asal bahan tanam dan konsentrasi Indole Butiric Acid (IBA) dengan tiga ulangan dan setiap perlakuan terdiri dari 14 stek. Faktor pertama adalah asal bahan stek yang terdiri dari bagian ujung, tengah, dan pangkal. Faktor kedua yaitu konsentrasi pemberian IBA empat taraf yaitu 0, 1500, 3000, dan 4500 ppm. Hasil penelitian menunjukkan bahwa perlakuan bahan tanam dan konsentrasi IBA dapat mempengaruhi pertumbuhan stek kopi liberika teutama pada kombinasi perlakuan stek bagian tengah dengan konsentrasi IBA 4500 ppm.

Abstract

Liberica coffee can be grown in peatland and has a specific flavor. To anticipate high demand of Liberica coffee product, it is very important to support the availability of high quality seedlings that need effective multiplication method of superior genotypes. This study aimed to investigate the effect of indole-butyric acid (IBA) concentration and cuttings wood origin and their interaction in the success of Liberica coffee cuttings. This research was held at Kaliwining Experimental Station, Indonesian Coffee and Cocoa Research Institute, designed using randomized complete block in factorial with two factors consisted of cutting wood origin and concentration of IBA. First factor was cuttings wood origin consisted of the tip, middle, and base, while second factor consisted of the concentration of IBA i.e. 0, 1500, 3000, and 4500 ppm. The results showed that the end of the shoots aged of 4-6 months were better part of shoot for cutting material. Percentage of the grown cutting reach up to 80%, while the middle and base part of shoots had a fairly low percentage of grown cutting, less than 43%. IBA a tended to increase rooted cuttings number. Combined treatment between cuttings material origin in the middle part with the IBA concentration of 4500 ppm showed the best root growth.
