PEMATAHAN DORMANSI BENIH DENGAN PERLAKUAN
SKARIFIKASI MEKANIS PENUSUKAN DAN ZPT ALAMI AIR KELAPA
TERHADAP PERKECAMBAHAN DAN PERTUMBUHAN BIBIT
KOPI ARABIKA (Coffea arabica L.) VARIETAS KOMASTI

ABSTRAK
Kopi tanaman unggulan Indonesia, namun ketersediaan benih terbatas karena
adanya masa dormansi. Tujuan penelitian mendapatkan skarifikasi mekanis
penusukan dan konsentrasi air kelapa yang tepat pada pematahan dormansi benih
terhadap perkecambahan dan pertumbuhan bibit Kopi Arabika Komasti. Metode
menggunakan faktorial yang disusun dalam Rancangan Acak Lengkap (RAL).
Faktor I skarifikasi mekanis yaitu tanpa penusukan dan dengan penusukan. Faktor
II yaitu konsentrasi ZPT alami air kelapa yakni 5, 10, 15 dan 20 ml/L dengan 3
ulangan. Hasil percobaan dianalisis dengan Analisis of Varance (ANOVA) taraf 5%
dan dilanjutkan uji Duncan’s Multiple Range Test (DMRT). Hasil penelitian
menunjukkan terdapat interaksi antara perlakuan skarifikasi mekanis dengan
penusukan dan konsentrasi ZPT air kelapa 20 ml/L dapat meningkatkan luas daun
dan bobot kering bibit Kopi Arabika Komasti. Perlakuan skarifikasi mekanis
dengan penusukan dapat mematahkan dormansi, meningkatkan perkecambahan
dan pertumbuhan bibit kopi Arabika Komasti. Zat Pengatur Tumbuh alami air
kelapa konsentrasi 20 ml/L dapat mematahkan dormansi, meningkatkan
perkecambahan dan pertumbuhan bibit kopi Arabika Komasti.

BREAKING SEED DORMANCY BY MECHANICAL SCARIFICATION
PRICKING AND NATURAL PGR TREATMENT OF COCONUT WATER
ON GERMINATION AND GROWTH OF SEEDLINGS ARABIC COFFEE
(Coffea arabica L.) VARIETY KOMASTI

ABSTRACT
Coffee is Indonesia's flagship plant, but the availability of seeds is limited due to
dormancy. The purpose of the study was to obtain the results of mechanical
scarification puncturing and the right concentration of coconut water to break the
dormancy of Komasti Arabica Coffee seeds. The method used factorial arranged in
a completely randomized design (CRD). Factor I mechanical scarification is
without puncturing and with puncturing. Factor II is the concentration of coconut
water PGR, namely 5, 10, 15, and 20 ml / L with 3 replications. Experimental results
were analyzed by Analysis of Variance (ANOVA) at a 5% level and continued by
Duncan's Multiple Range Test (DMRT). The results showed that there was an
interaction of mechanical scarification treatment with pricking and coconut water
PGR concentration of 20 ml/L can increase the leaf area and dry weight of Komasti
Arabica Coffee seedlings. Mechanical scarification treatment with pricking can
break dormancy, and increase germination and growth of Arabica Komasti coffee
seedlings. Coconut water growth regulator at a concentration of 20 ml/L can break
dormancy, and increase germination and growth of Arabica Komasti coffee
seedlings.
