      Abstract
      ALIFIA KINANTI PRASTUTI. Pengaruh Jenis dan Dosis Pupuk Anorganik pada Bibit Kopi Arabika (Coffea arabica L.) di Kebun Kayumas PT Perkebunan Nusantara XII Situbondo Jawa Timur. Dibimbing oleh EDI WIRAGUNA. Pembibitan merupakan aspek penting dalam budidaya tanaman kopi. Upaya peningkatan produktivitas kopi dapat dilakukan melalui pemupukan dan pemanfaatan media tanam yang baik. Penggunaan pupuk merupakan salah satu hal yang harus diperhatikan dengan tepat jenis, dosis, waktu dan cara. Penelitian ini bertujuan untuk mempelajari pemupukan di pembibitan kopi, meliputi pemilihan jenis pupuk dan penentuan dosis. Parameter yang diteliti yaitu tinggi tanaman, jumlah daun, dan diameter batang. Penelitian menggunakan Rancangan Kelompok Lingkungan Teracak (RKLT) dengan 6 perlakuan, 3 ulangan. Perlakuan tersebut adalah N1 = Urea 3 gram, N2 = Urea 5 gram, N3 = Urea 7 gram dan P1 = NPK 3 gram, P2 = 5 gram, P3 = 7 gram. Hasil penelitian menunjukkan pada tinggi tanaman tidak ditemukan adanya perbedaan nyata kepada setiap perlakua. Variasi dosis pupuk berpengaruh nyata terhadap jumlah daun pada bibit kepelan kopi, sedangkan untuk diameter batang faktor yang berpengaruh sangat nyata yaitu pemilihan jenis pupuk berupa pupuk NPK.
       
      ALIFIA KINANTI PRASTUTI. Effect of Type and Dosage of Inorganic Fertilizer on Arabica Coffee Seedlings (Coffea arabica L.) in the Kayumas Plantation of PT Perkebunan Nusantara XII Situbondo, East Java. Supervised by EDI WIRAGUNA. Seeding is an important aspect in cultivating coffee plants. Efforts to increase coffee productivity can be done through fertilization and the use of good planting media. The use of fertilizer is one of the things that must be considered with the right type, dose, time and method. This research aims to study fertilization in coffee nurseries, including selecting the type of fertilizer and determining the dose. The parameters studied were plant height, number of leaves, and stem diameter. The research used a Randomized Environmental Group Design (RKLT) with 6 treatments, 3 replications. The treatments are N1 = Urea 3 grams, N2 = Urea 5 grams, N3 = Urea 7 grams and P1 = NPK 3 grams, P2 = 5 grams, P3 = 7 grams. The results of the research showed that there were no significant differences in plant height in each treatment. Varying fertilizer doses have a significant effect on the number of leaves on coffee kepelan seedlings, while for stem diameter the factor that has a very significant influence is the choice of fertilizer type in the form of NPK fertilizer.
