Abstrak. Tomat (Solanum lycopersicum L.) merupakan sayuran buah yang bernilai gizi tinggi karena mengandung vitamin, mineral, serat, serta senyawa bioaktif yang bermanfaat bagi kesehatan. Salah satu upaya untuk meningkatkan pertumbuhan dan hasil tanaman tomat adalah dengan menggunakan bahan organik seperti eco enzyme dan pupuk anorganik NPK. Penelitian ini bertujuan untuk menentukan konsentrasi eco enzyme dan dosis pupuk NPK yang tepat untuk meningkatkan pertumbuhan dan hasil tanaman tomat. Penelitian dilakukan di Kebun Percobaan dan Laboratorium Ilmu dan Teknologi Benih, Fakultas Pertanian Universitas Syiah Kuala dari Januari hingga Mei 2025. Rancangan yang digunakan adalah Rancangan Acak Kelompok (RAK) pola faktorial 4 × 4 dengan dua faktor, yaitu konsentrasi eco enzyme (0, 20, 40, dan 60 ml L⁻¹) dan dosis pupuk NPK (0, 200, 400, dan 600 kg ha⁻¹) dengan tiga ulangan. Tanaman ditanam dalam polibag berukuran 30 cm × 40 cm dengan jarak tanam 50 cm × 50 cm. Hasil penelitian menunjukkan bahwa konsentrasi eco enzyme berpengaruh sangat nyata terhadap panjang akar dan nyata terhadap kadar vitamin C, dengan hasil terbaik pada 60 ml L⁻¹. Dosis NPK berpengaruh sangat nyata terhadap jumlah buah per tanaman, berat buah per tanaman, berat per buah, dan volume akar, dengan dosis optimal 600 kg ha⁻¹. Terdapat interaksi berpengaruh sangat nyata antara konsentrasi eco enzyme dan dosis NPK terhadap kadar vitamin C dan panjang akar. Kombinasi perlakuan terbaik pada kadar vitamin C konsentrasi eco enzyme 20 ml L-1 dan dosis NPK 200 kg ha-1. Kombinasi perlakuan terbaik pada panjang akar konsentrasi eco enzyme 60 ml L-1 dan dosis NPK 400 kg ha-1.

Abstrac. Tomatoes (Solanum lycopersicum L.) are highly nutritious vegetables because they contain vitamins, minerals, fiber, and bioactive compounds that are beneficial for health. One way to improve tomato plant growth and yield is by using organic materials such as eco enzymes and inorganic NPK fertilizers. This research aims to determine the appropriate concentration of eco enzymes and NPK fertilizer dosages to improve tomato plant growth and yield. The research was conducted at the Experimental Farm and Seed Science and Technology Laboratory, Faculty of Agriculture, Syiah Kuala University, from January to May 2025. The experimental design used was a Randomized Block Design (RBD) with a 4 × 4 factorial pattern, involving two factors: eco enzyme concentration (0, 20, 40, and 60 ml L⁻¹) and NPK fertilizer dosages (0, 200, 400, and 600 kg ha⁻¹), with three replications. The plants were grown in polybags measuring 30 cm × 40 cm with a planting distance of 50 cm × 50 cm. The results showed that eco enzyme concentration had a very significant effect on root length and a significant effect on vitamin C content, with the best results at 60 ml L⁻¹. The NPK fertilizer rate had a highly significant effect on the number of fruits per plant, fruit weight per plant, fruit weight per fruit, and root volume, with the optimal rate being 600 kg ha⁻¹. There was a highly significant interaction between eco enzyme concentration and NPK fertilizer rate on vitamin C content and root length. The best treatment combination for vitamin C levels was a concentration of 20 ml L-1 eco enzyme and an NPK dosages of 200 kg ha-1. The best treatment combination for root length was a concentration of 60 ml L-1 eco enzyme and NPK dosages of 400 kg ha-1.
