Abstract
Pakcoy cultivation can be done with a hydroponic system. One of the main obstacles that inhibits production both in quality and quantity is the presence of pests, one of which is Spodoptera litura F attack. The control has be done but almost using synthetic pesticides. It is more practice to controlling the attack of plant-disturbing organisms, however can cause negative impact. So it needs alternative environmentally friendly controls. One of them is by using weed plants such as kipait which are reported to have the potential to reduce damage by plant-disturbing organisms. The research was carried out in the greenhouse of the Experimental Garden of Padjadjaran University, Ciparanje, Jatinangor, Sumedang Regency, West Java. Research time is August 2019 - September 2019. The research method used is using a completely randomized design (CRD) method with 5 treatments consisting of A = AB mix fertilizer, B = liquid organic fertilizer, C = AB mix fertilizer + Spodoptera litura F, D = Liquid organic fertilizer + Spodoptera litura F, and E = Liquid organic fertilizer + Spodoptera litura F + POC Spray. The results showed that there was no effect of Liquid Organic Kipait Fertilizer (Tithonia diversifolia) on the growth of pakcoy plants, but liquid Kipait organic fertilizer was able to suppress the population of Spodoptera litura. F and able to reduce the intensity of damage Pakcoy plants.
