Abstract

ABSTRACT Liberica coffee from Tungkal Jambi is an important plantation commodity in Jambi Province; however, seedling development is constrained by slow seed germination due to physical dormancy, resulting in low nursery efficiency. Seed soaking using eco-enzyme has the potential to serve as an alternative approach to overcome this constraint. This study aimed to evaluate the germination response of Liberica coffee seeds to different eco-enzyme concentrations and soaking durations. The experiment was conducted at the Teaching and Research Farm Greenhouse, Faculty of Agriculture, Universitas Jambi, from January to April 2025, using a completely randomized factorial design with two factors: eco-enzyme concentration (0, 25, 50, 75, and 100%) and soaking duration (12 and 24 h). The observed variables included germination percentage, longest hypocotyl length, longest root length, hypothetical vigor index, and seedling dry weight. The results showed no interaction between eco-enzyme concentration and soaking duration. Application of eco-enzyme at concentrations of 25–100% increased the longest root length of Liberica coffee seedlings, but did not improve other germination and seed vigor parameters. The best germination response of liberica coffea seeds is obtained at an ecoenzyme concentration of 25% and a soaking time of 12 hours.   Keywords:  ecoenzyme, germination, liberica tungkal jambi coffea   ABSTRAK Kopi Liberika Tungkal Jambi merupakan komoditas perkebunan penting di Provinsi Jambi, namun pengembangan bibitnya masih terkendala oleh lambatnya perkecambahan benih akibat dormansi fisik, sehingga menurunkan efisiensi pembibitan. Perlakuan perendaman benih menggunakan ekoenzim berpotensi menjadi salah satu solusi untuk mengatasi kendala tersebut. Penelitian ini bertujuan mengevaluasi respons perkecambahan benih kopi Liberika terhadap variasi konsentrasi ekoenzim dan lama perendaman. Penelitian dilaksanakan di Rumah Kaca Teaching and Research Farm Fakultas Pertanian Universitas Jambi pada Januari–April 2025 menggunakan Rancangan Acak Lengkap (RAL) faktorial dua faktor, yaitu konsentrasi ekoenzim (0, 25, 50, 75, dan 100%) dan lama perendaman (12 dan 24 jam). Variabel yang diamati meliputi daya berkecambah, panjang hipokotil terpanjang, panjang akar terpanjang, indeks vigor hipotetik, dan bobot kering kecambah. Hasil penelitian menunjukkan tidak terdapat interaksi antara konsentrasi ekoenzim dan lama perendaman. Pemberian ekoenzim pada konsentrasi 25–100% mampu meningkatkan panjang akar terpanjang kecambah kopi Liberika, namun belum meningkatkan variabel perkecambahan dan vigor benih lainnya. Respons perkecambahan benih kopi liberika terbaik diperoleh pada konsentrasi ekoenzim 25% dan lama perendaman 12 jam.   Kata kunci: ekoenzim, kopi liberika tungkal jambi, perkecambahan

Abstract

Oil palm is one of Indonesia’s major plantation commodities and plays an important role as a source of national foreign exchange. The decline in oil palm productivity due to the high proportion of damaged and unproductive plants has increased the need for replanting supported by the production of high-quality seedlings. The success of seedling production is influenced by growing media and fertilization, particularly in Ultisol soils, which are characterized by low organic matter content. This study aimed to evaluate the growth response of oil palm seedlings to the application of rice straw compost and NPKMg fertilizer and to determine the best treatment combination in the main nursery. The experiment was conducted for three months using a Completely Randomized Design (CRD) with five treatments: p0 = 100% of the recommended dose of NPKMg p1 = 200 g rice straw compost + 50% of the recommended dose of NPKMg; p2 = 250 g rice straw compost + 50% of the recommended dose of NPKMg; p3 = 300 g rice straw compost + 50% of the recommended dose of NPKMg; and p4 = 350 g rice straw compost + 50% of the recommended dose of NPKMg, with four replications. Data were analyzed using analysis of variance (ANOVA), followed by the Least Significant Difference (LSD) test at the 5% significance level. The results showed that the combination of rice straw compost and NPKMg fertilizer improved seedling height and shoot dry weight, whereas leaf number, stem diameter, root dry weight, shoot-to-root ratio, and seedling quality index did not improve. The application of 250 g rice straw compost combined with 50% of the recommended dose of NPKMg (15-15-6-4) was the best treatment and produced seedling growth comparable to that obtained with the 100% recommended dose of NPKMg. Therefore, this combination is recommended as an alternative to reduce the use of inorganic fertilizer by up to 50%.
