Abstract

Selada, yang juga dikenal dengan nama ilmiah Lactuca sativa L, merupakan tanaman hortikultura yang menjanjikan dan memiliki nilai ekonomi tinggi. Tanaman ini kaya akan mineral, vitamin, antioksidan, potassium, zat besi, folat, karoten, vitamin C, dan vitamin E. Dalam bercocok tanam selada secara hidroponik, metode Deep Flow Technique (DFT) terbukti efektif. Penelitian ini menggunakan Rancangan Acak Kelompok (RAK) untuk menguji pengaruh pemberian spektrum LED putih dan biru pada tanaman selada. Ada empat perlakuan yang diujikan: P1 (tanpa LED), P2 (LED biru dan putih 1:3), P3 (LED biru dan putih 1:1), dan P4 (LED biru dan putih 3:1). Setiap perlakuan diulang lima kali, dengan dua tanaman sampel pada setiap pengulangan, sehingga total terdapat 40 tanaman sampel. Parameternya melibatkan tinggi tanaman, jumlah daun, panjang akar, bobot akar, warna daun, kadar antioksidan, berat konsumsi, lebar daun, diameter batang, dan konsumsi listrik saat panen. Pengukuran dilakukan setiap minggu selama lima minggu. Hasil penelitian menunjukkan bahwa lampu LED memiliki pengaruh signifikan terhadap jumlah daun, diameter batang, bobot akar, dan berat konsumsi, tetapi tidak berpengaruh signifikan terhadap tinggi tanaman, lebar daun, panjang akar, kadar antioksidan, dan warna daun. Berdasarkan penelitian ini, dapat disimpulkan bahwa perlakuan 4 (LED biru dan putih 3:1) memberikan hasil terbaik, dengan jumlah daun mencapai 27,4 helai, panjang akar 18,95 cm, bobot akar 23,2 g, berat konsumsi 109 g, diameter batang 8,2 mm, dan kadar antioksidan sebesar 42,39% inhibisi. Lettuce, also known by the scientific name Lactuca sativa L, is a promising horticultural crop and has high economic value. This lettuce plant is rich in minerals, vitamins, antioxidants, potassium, iron, folate, carotene, vitamin C and vitamin E. To grow lettuce hydroponically, the effective Deep Flow Technique (DFT) system can be used. This research used a Randomized Block Design (RAK) to test the effect of giving white and blue LED spectrum to lettuce plants. There are four treatments given, namely: P1: There are four treatments given, namely P1: No LED, P2: blue and white LED (1:3), P3: blue and white LED (1:1), and P4: LED blue and white (3:1). Each treatment was repeated five times, and each repetition used two sample plants. Thus, in total there were 40 sample plants. Several parameters measured in this research include plant height, number of leaves, root length, root weight, leaf color, antioxidant content, consumption weight, leaf width, stem diameter, and electricity consumption during harvest. Measurements were carried out every week for five weeks. The research results showed that the use of LED lights had a real influence on the number of leaves, stem diameter, root weight and consumption weight. It has no real effect on plant height, leaf width, root length, antioxidant levels and leaf color. Based on the research results, it can be concluded that treatment 4 (blue and white LED 3:1) obtained the best results in the number of leaves 27.4, root length 18.95 cm, root weight 23.2 g, consumption weight 109 g, stem diameter 8.2 mm, and antioxidant levels of 42.39% inhibition.
