Abstrak. kopi (coffea canephora l.) merupakan salah satu komoditi perkebunan penting di indonesia yang telah berhasil menembus pasar ekspor internasional. amerika serikat, mesir, jepang dan italia merupakan beberapa negara utama yang menerima ekspor kopi dalam jumlah besar dari indonesia. permasalahan yang sering timbul dalam budidaya tanaman kopi adalah tingkat naungan yang tidak sesuai pada fase pembibitan yang akan mempengaruhi pertumbuhan serta produksi dan cita rasa kopi. penelitian ini bertujuan untuk mengetahui pengaruh intensitas naungan dan jenis media tanam terhadap pertumbuhan bibit kopi robusta. penelitian dilaksanakan di kebun percobaan fakultas pertanian universitas syiah kuala dengan menggunakan rancangan acak tersarang pola 3x4 dengan 4 ulangan, mencakup tiga taraf naungan (0%, 30%, dan 60%) dan empat jenis media tanam (tanah, tanah + pupuk kandang 3:1, tanah + sekam padi 3:1, dan tanah + arang sekam 3:1). hasil penelitian menunjukkan bahwa media tanam yang tersarang dalam naungan berpengaruh nyata terhadap tinggi tanaman, diameter pangkal batang, berat biomassa, serta berat akar dan daun, namun tidak berpengaruh terhadap jumlah daun. perlakuan terbaik pada kombinasi naungan 60% dan media tanam tanah + pupuk kandang. penggunaan intensitas naungan yang tepat dan media tanam organik dapat meningkatkan kualitas pertumbuhan bibit kopi robusta secara signifikan. kata kunci: kopi robusta, naungan, media tanam

Abstract. Coffee (Coffea canephora L.) is one of Indonesia's major plantation commodities that has successfully entered the international export market, with key destination countries including the United States, Egypt, Japan, and Italy. One of the common challenges in coffee cultivation is the inappropriate level of shading during the seedling phase, which can affect growth, yield, and flavor quality. This study aims to determine the effect of shading intensity and planting media type on the growth of robusta coffee seedlings. The research was conducted at the Experimental Garden of the Faculty of Agriculture, Syiah Kuala University, using a nested randomized design with a 3×4 pattern and 4 replications. The treatments consisted of three shading levels (0%, 30%, and 60%) and four types of growing media (soil, soil + manure, soil + rice husks, and soil + charcoal husks). The results showed that the combination of shading and planting media significantly affected plant height, stem base diameter, biomass, as well as root and leaf weight, but had no significant effect on the number of leaves. The best results were from the combination of 60% shading and soil + manure growing medium. Proper shading intensity and organic planting media were proven to significantly enhance the growth of robusta coffee seedlings Keywords: Robusta Coffee, Shading, Growing Media
