Papaya tree is one of the ordinary plants found in Indonesia and is often found at urban or rural areas, because papaya tree can easily grow everywhere. Papaya leaf gives the benefit that can be used to decompose the waste. The waste which becomes decompose is good compose, because the waste becomes macromolecule and easily to compose with the soil. The independent variables are the better concentration from the extract. The experiment was conducted by using papaya leaves, it is pounded, in order to eliminate the stink of crab and make the food waste into decompose. That is (The process of the experiment on making 5 gr, and 10 gr) because papaya leaf contains papain enzyme which can decompose the waste. The steps to make papaya leave extract are as follows: wash the papaya leaves, then grind or pound them, after that squeeze the papaya leaves which have already been pounded, and finally we get the papaya leaf extract. From the evaluation of the experiment, the kind of the concentration from the better extract is 75%, because the waste can decompose faster than the other extract. So it proves that papaya leaf extract can eliminate the stink of crab and change the food waste to be composted.
