Pengaruh Pupuk Organik Cair (POC) Bekatul Terhadap Pertumbuhan Selada (Lactuca sativa L.) yang dibudidayakan Secara Hidroponik.

Hydroponic lettuce cultivation using AB-mix nutrients has several weaknesses, one of which is that the price of nutrients is relatively expensive and difficult to obtain in small towns. Rice bran liquid organic fertilizer (LOF) has the potential to be a substitute or supplementary nutrient in hydroponic cultivation; it has a fairly high nitrogen content (2.08%). This research aims to examine the effect of rice bran POC on the yield of lettuce plants cultivated hydroponically. The research used a non-factorial Randomized Group Design (RGD), consisting of 3 treatments, namely P1 (rice bran LOF 5 ml/l), P2 (AB-mix 1500 ppm), and P3 (AB-mix 1500 ppm + rice bran LOF 5 ml/l), which were repeated 10 times to obtain 30 experimental units. The observation variables in this research were plant height, number of leaves, wet weight, and dry weight of harvest. Data analysis was carried out using analysis of variance; if there was a real effect, a 5% BNT test was carried out. The results of the research showed that rice bran POC (5 ml/l) was not able to be used as the sole nutrient in hydroponic lettuce cultivation, AB-mix 1500 ppm nutrition treatment + 5 ml/l rice bran LOF gave the best and highest results in plant height, number of leaves, wet weight, and lettuce dry weight.
