Green mustard is one of the vegetabels that is quite popular for Indonesian people, it is also use quite diverse. Green mustard production according to BPS data for 2019, states that from 2017 to 2019, respectively 627,598 tons, 635,990 tons, 652,727 tons. The increase in the amount of production is still not able to meet the need and demand for green mustard. This increased demand has not been matched by the availability of land. Currently there is a significant conversion of agricultural land functions on 2016 that there is a conversion of 96,512 ha / year of paddy fields in Indonesia. Apart from that, another problem faced by farmers is the infrequent and expensive price of fertilizers due to the elimination of subsidies provided by the government. So one solution given to farmers is the cultivation of green mustard plants (Brassica juncea L.) var. Tosakan with a floating raft hydroponic sistem using nutrients from urin of rabbit liquid fertilizer. The research was conducted to study the effectiveness of using urin of rabbit in green mustard for planting a floating raft hydroponic cultivation sistem. The cultivation of green mustard plants is carried out in the open yard. This research was conducted in several stages. The first is seeding. Green mustard seeds are sown until they are 14 days old. Followed by making the installation. Then move the plant after 14 days of mossy mustard seeds. Performed maintenance by stirring the nutrient solution and adjusting the parameters every 3 days. After that, data analysis was carried out. The parameters observed were plant height, number of leaves, wet weight, dry weight, moisture content, and chlorophyll content. The nutrients provided were AB Mix, Hoagland, rabbit urin, and rabbit urin with peanut plants that were dissolved directly into the research tray. Arranged based on a randomized block design (RBD) with the concentration of nutrients for each tray at AB Mix and Hoagland 5 ml / L, while in pure rabbit urin and rabbit urin with peanut plants 10 ml / L water, with each treatment there are 3 trays, and each tray. There are 5 plant pots with parameters of observation of plant height, number of leaves, wet weight, dry weight, moisture content and chlorophyll content. The results of this study indicate that the results of this study indicate that the ratio between AB mix and Hoagland solutions, the effectiveness of giving rabbit urin fertilizer (UK) and rabbit urin mixed with peanuts (UKK) on the growth of mustard greens is 30% (UK). and 31.85% (UKK) compared to AB mix (AB), and 29.13% (UK) and 30.97% (UKK) compared to Hoagland (AH).
