Abstract
Bleberan Village, Gunungkidul Regency, Yogyakarta has an oyster mushroom farming business that has been
working with Korea since 2016. The problem experienced by oyster mushroom farmers in Bleberan village is that there is no
use of unused baglog waste so that it pollutes the environment. So that efforts are needed so that the baglog waste does not
pollute the environment, namely by utilizing it into compost that is of selling value. The method of taking materials is a method
of taking directly where the composting material is taken in the farmer^s coup. The measured parameters are Temperature,
pH, C-Organic, N Total, C/N Ratio to the weight of baglog raw materials which is constant 2 kg and varied on the addition of
cow dung. The results showed that the average content of C-Organic content was 60% and N Total 1% and C/N the average
ratio was 40, this shows that the compost for oyster mushroom baglog waste has not met the quality standards of SNI 19-
7030-2004. The sale of baglog waste compost has a good selling value with an estimated production of 1200 kg per year with
a BEP of 446.2 kg, which when farmers can sell around 446.2 kg per year, it will already reap profits. With this, farmers have
been able to implement the Green Economy in oyster mushroom production activities where unused baglog waste can be
resold by converting it into compost.
