Abstract
EKSPLORASI DAN KARAKTERISASI MORFOLOGI TANAMAN KOPI (Coffea sp.) DI KECAMATAN GUNUANG OMEH, BUKIK BARISAN DAN HARAU KABUPATEN LIMA PULUH KOTA Abstrak Kopi (Coffea sp.) merupakan komoditas perkebunan strategis yang berkontribusi besar dalam devisa Negara. Karakterisasi morfologi tanaman kopi bertujuan untuk mendeskripsikan berbagai sifat atau ciri morfologis tanaman kopi yang tumbuh di perkebunan rakyat. Tujuan penelitian ini adalah untuk mengkarakterisasi morfologi dan melihat tingkat keragaman tanaman kopi Arabika ( Coffea arabica L.) dan kopi Robusta (Coffea canephora L.) di daerah tersebut. Penelitian ini telah dilakukan pada bulan Mei sampai Agustus 2025. Penelitian yang digunakan adalah berupa survei dengan metode (Purposive sampling) dengan mempertimbangkan kriteria tanaman yang telah menghasilkan, berumur ≥5 tahun serta tidak terserang hama dan penyakit. Metode pengumpulan data dilakukan melalui pengamatan terhadap bagian-bagian morfologi pada setiap sampel tanaman kopi. Data yang terkumpul dianalisis menggunakan metode deskriptif, sementara analisis tingkat kemiripan dilakukan dengan bantuan perangkat lunak NTSYS versi 2.10. Hasil penelitian kopi Arabika (Coffea arabica L.) terdapat 10 karakter morfologi yang memiliki nilai variabilitas luas dan 9 karakter mempunyai variabilitas sempit dengan tingkat keragaman berkisar antara 34%-89%. Sedangkan, hasil penelitian kopi Robusta (Coffea canephora L.) terdapat 7 karakter morfologi yang memiliki nilai variabilitas luas dan 12 karakter mempunyai variabilitas sempit dengan tingkat keragaman antara 35%-89%. Analisis keragaman pada kopi Arabika dan Robusta membentuk dua kelompok utama yaitu Cluster 1 dan Cluster 2. Kata kunci: eksplorasi, karakterisasi, morfologi, tanaman kopi, variabilitas MORPHOLOGICAL EXPLORATION AND CHARACTERIZATION COFFEE PLANT (Coffea sp.) IN THE DISTRICT OF GUNUANG OMEH, BUKIK BARISAN AND HARAU LIMA PULUH KOTA REGENCY Abstract Coffee (Coffea sp.) is a strategic plantation commodity that contributes significantly to the country's foreign exchange earnings. The morphological characterization of coffee plants aims to describe the various morphological traits or characteristics of coffee plants grown on smallholder plantations. The objective of this study is to characterize the morphology and examine the level of diversity of Arabica coffee (Coffea arabica L.) and Robusta coffee (Coffea canephora L.) plants in the region. This research was conducted from May to August 2025. The research used a survey with a purposive sampling method, considering the criteria of plants that had produced, were ≥5 years old, and were not affected by pests and diseases. The data collection method was carried out through observation of the morphological parts of each coffee plant sample. The collected data were analyzed using descriptive methods, while the similarity level analysis was performed using NTSYS version 2.10 software. The results of the Arabica coffee (Coffea arabica L.) study showed that there were 10 morphological characters with wide variability and 9 characters with narrow variability, with a diversity level ranging from 34% to 89%. Meanwhile, the results of the Robusta coffee (Coffea canephora L.) study showed that there were 7 morphological characters with wide variability and 12 characters with narrow variability with a diversity level ranging from 35% to 89%. The diversity analysis of Arabica and Robusta coffee formed two clusters. Keywords: exploration, characterization, morphology, coffee plant, variability
