Abstract
Genetic diversity of Robusta coffee plants (Coffea canephora) can be known through the identification of morphological characters. Local Robusta coffee is found in the Karang Mountain area, especially in Juhut Village, Citaman Village, and Sukarena Village, which has been cultivated for generations. This study aims to determine the diversity and morphological characteristics between samples of Robusta coffee plants in the region. The research was conducted exploratively and descriptively using a purposive sampling technique, with observation variables in the form of vegetative and generative morphological characters. The results showed the existence of morphological diversity and distinctive characters between samples. In Juhut Village, plants tend to have medium height (2.5-4 m), dominant secondary branching, oval-shaped stipules, elliptical leaves with apiculate tips and margins, round fruits, and ovoid and oblong seeds. In Citaman Village, plants are taller (4-5 m), with very few primary branches, equilateral triangular stipules, elliptical leaves with apiculate tips and margins, round fruits, and brownish-yellow ovoid seeds. Meanwhile, in Sukarena Village, plant height is also medium (2.5-4 m), with branching up to the tertiary level, equilateral triangular stipules, elliptical leaves with apiculate and spatulate tips, rippled leaf margins, slightly rounded fruits, and ovoid seeds.

| Additional Information: | Keragaman genetik tanaman kopi Robusta (Coffea canephora) dapat diketahui melalui identifikasi karakter morfologi. Kopi Robusta lokal terdapat di daerah Gunung Karang, khususnya di Desa Juhut, Desa Citaman, dan Desa Sukarena yang telah dibudidayakan secara turun temurun. Penelitian ini bertujuan untuk mengetahui keragaman dan karakter morfologi antar sampel tanaman kopi Robusta di wilayah tersebut. Penelitian dilakukan secara eksploratif dan deskriptif dengan menggunakan teknik purposive sampling, dengan variabel pengamatan berupa karakter morfologi vegetatif dan generatif. Hasil penelitian menunjukkan adanya keragaman morfologi dan karakter yang khas antar sampel. Di Desa Juhut, tanaman cenderung memiliki tinggi sedang (2,5-4 m), percabangan sekunder dominan, bonggol berbentuk lonjong, daun berbentuk elips dengan ujung dan tepi meruncing, buah berbentuk bulat, dan biji berbentuk bulat telur dan lonjong. Di Desa Citaman, tanaman lebih tinggi (4-5 m), dengan cabang primer yang sangat sedikit, bonggol berbentuk segitiga sama sisi, daun berbentuk elips dengan ujung dan tepi yang meruncing, buah berbentuk bulat, dan biji berbentuk bulat telur berwarna kuning kecoklatan. Sementara itu, di Desa Sukarena, tinggi tanaman juga sedang (2,5-4 m), dengan percabangan hingga tingkat tersier, pertulangan berbentuk segitiga sama sisi, daun berbentuk elips dengan ujung menjari dan bergerigi, tepi daun berombak, buah sedikit membulat, dan biji bulat telur. | |||||||||
