Kelapa sawit (elaeis guineensis jacq.) merupakan salah satu komoditas perkebunan yang mengalami perluasan areal tanam secara pesat dibandingkan dengan tanaman perkebunan lainnya, serta memiliki nilai ekonomi yang tinggi. salah satu upaya untuk meningkatkan pertumbuhan dan perkembangan bibit kelapa sawit adalah dengan penggunaan komposisi media tanam dan dosis pupuk n, p dan k. tujuan dari penelitian ini mengetahui pengaruh komposisi media tanam dan dosis pupuk n, p dan k terhadap pertumbuhan dan perkembangan di pembibitan utama dan memperoleh komposisi media tanam terbaik bagi pertumbuhan bibit kelapa sawit di pembibitan utama. penelitian ini telah dilaksanakan di unit rumah kompos bank sampah universitas syiah kuala (bsu), darussalam, banda aceh (5034’02”n-95022”25”e) dengan ketinggian 4,14 mdpl, labortorium hortikultura, laboratorium gulma dan laboratorium benih, fakultas pertanian universitas syiah kuala. penelitian ini berlangsung dari bulan november 2024 sampai dengan mei 2025. penelitian ini menggunakan rancangan acak kelompok pola faktorial 4 × 3 dengan 3 ulangan. faktor pertama adalah kombinasi media tanam yang terdiri dari 4 taraf yaitu m0 (tanah), m1 (tanah 50% : sekam padi 50%), m2 (tanah 50% : kompos 50%), m3 (tanah 50% : sekam padi 25% : kompos 25%), faktor kedua adalah dosis pupuk n, p dan k yaitu n1 (n, p dan k 50% (0,6 g urea, 0,37 g, sp-36, 0,37 g kcl tanaman-1)), n2 (n, p dan k 100% (1 g urea, 0,75 g sp-36, 0,75 g kcl tanaman-1)), n3 (n, p dan k 150% (1,8 g urea, 1,12 g, sp-36, 1,12 g kcl tanaman-1)). peubah yang diamati adalah tinggi tanaman, diameter batang, jumlah daun, luas daun, klorofil daun, panjang akar, bobot brangkasan basah atas, bobot brangkasan basah bawah, bobot berangkas basah keseluruhan, bobot brangkasan kering atas, bobot brangkasan kering bawah dan bobot brangkasan kering keseluruhan. hasil penelitian menunjukkan kombinasi media tanam berpengaruh sangat nyata terhadap luas daun dan bobot berangkasan basah atas 90 hspt, kemudian berpengaruh nyata pada tinggi tanaman, bobot brangkasan kering atas dan bobot brangkasan kering keseluruhan 90 hspt. pertumbuhan bibit kelapa sawit terbaik dijumpai pada pengunaan komposisi media tanam perbandingan tanah 50% : kompos 50%. dosis pupuk n, p dan k berpengaruh tidak nyata terhadap peubah yang diamati. interaksi antara media tanam dan dosis pupuk n, p dan k berpengaruh tidak nyata terhadap semua peubah yang diamati.

Oil palm (Elaeis guineensis Jacq.) is one of the plantation commodities that has experienced rapid expansion of planting areas compared to other plantation crops, and has high economic value. One effort to improve the growth and development of oil palm seedlings is by using the composition of planting media and doses of N, P and K fertilizers. The purpose of this study was to determine the effect of the composition of planting media and doses of N, P and K fertilizers on growth and development in the main nursery and to obtain the best planting media composition for the growth of oil palm seedlings in the main nursery. This research was conducted in the Waste Bank Compost House unit of Syiah Kuala University (BSU), Darussalam, Banda Aceh (5034’02”N-95022”25”E) at an altitude of 4.14 meters above sea level, Horticulture Laboratory, Weed Laboratory and Seed Laboratory, Faculty of Agriculture, Syiah Kuala University. This research took place from November 2024 to May 2025. This research used a 4 × 3 factorial Randomized Block Design with 3 replications. The first factor was a combination of planting media consisting of 4 levels, namely M0 (soil), M1 (soil 50%: rice husk 50%), M2 (soil 50%: compost 50%), M3 (soil 50%: rice husk 25%: compost 25%), the second factor was the dose of N, P and K fertilizers, namely N1 (N, P and K 50% (0.6 g Urea, 0.37 g, SP-36, 0.37 g KCl plant-1)), N2 (N, P and K 100% (1 g Urea, 0.75 g SP-36, 0.75 g KCl plant-1)), N3 (N, P and K 150% (1.8 g Urea, 1.12 g, SP-36, 1.12 g KCl plant-1)). The variables observed were plant height, stem diameter, number of leaves, leaf area, leaf chlorophyll, root length, upper wet stalk weight, lower wet stalk weight, total wet stalk weight, upper dry stalk weight, lower dry stalk weight and total dry stalk weight. The results showed that the combination of planting media had a very significant effect on leaf area and upper wet stalk weight at 90 days after planting, then had a significant effect on plant height, upper dry stalk weight and total dry stalk weight at 90 days after planting. The best growth of oil palm seedlings was found in the use of a planting media composition with a soil ratio of 50%: 50% compost. The doses of N, P, and K fertilizers had no significant effect on the observed variables. The interaction between the planting medium and the doses of N, P, and K fertilizers had no significant effect on all observed variables.
