Differences in Pakcoy Cultivation Media in The Aquaponic Systems With Tilapia Fish

Abstract

Urban Agriculture with an aquaponic system can be land intensification, in order to meet the needs of fresh vegetables and fruits for urban communities. Aquaponics is a cultivation technique that combines two organisms, namely fish and plants. Fish waste and leftover feed containing organic matter in the water can be utilized by plants for their growth. Pakcoy (Brassica rapa L.) is a vegetable from the Brassicaceae family whose leaves are used as food in the form of vegetables. This study aims to determine the appropriate planting media for use in an aquaponic system with Tilapia and Pakcoy plants. The study was conducted at the Ciganjur Fish Seed Center, Center for Production, Inspection and Certification of Fishery Products, South Jakarta. The research design used was a Completely Randomized Design (CRD) with 5 treatments, namely, P0 = Split stone with coconut shell charcoal (Control), P1 = Split stone with Malang sand, P2 = Split stone, P3 = Split stone with fern roots, P4 = Split stone with palm fiber. Based on the research results, it was concluded that the most suitable media for growing Pakcoy plants with tilapia fish in the aquaponic system is a mixture of split stone and Malang sand because it can have a very real effect on the wet weight and consumption weight of Pakcoy
