ABSTRACT
Utilization of agricultural waste can be done as a form of optimizing the utilization of local resources and to minimize environmental damage. One of them is to take advantage of the growing media waste white oyster mushroom (Pleurotus ostreatus) as compost, known as baglog. During this new baglog used as animal feed, while the compost has not been utilized intentions. However, baglog have a low nutrient content, so it needs to be combined with another in order to be used as a substitute for chemical fertilizers and pesticides that are qualified. Tithonia diversifolia is an annual weed that has the potential as a source of nutrients, containing 3.50 % N, 0.37 % P, and 4.10 % K. The study consisted of two stages of implementation, namely: 1) composting, and 2) test the quality of compost. Composting and analysis in the Laboratory of Agricultural Technology STP HAS for 6 months. This research was conducted to find the best compost formula rich in nutrients by adding Tithonia diversifolia, as well as the use of paunch manure composter. Formula best compost rich in nutrients with the addition of 50 % Tithonia diversifolia. The influence of the old oyster mushroom composting waste that is best at 60 days of composting. The addition of 50 % Tithonia and composting 60 days old showed the best formulation in composting plus. With the addition of some kind of Tithonia able to increase the level of nutrient content when compared with no Tithonia.
