The palm oil plant (Elaeis guineensis) is one of the industrial plants that was introduced commercially in Malaysia around 1870 that is 150 years ago and is now one of the main commodities capable of generating national income. However, the country's oil palm industry, which is currently growing rapidly, especially in the fresh fruit production sector, will have an impact on the management of oil palm waste. Agricultural waste management is one of the important agendas under the government through MAFI's environmental considerations, the concept of agricultural waste management and others. This research aims to innovate waste from crude palm oil (CPO) dregs to mushroom blocks. Crude palm oil dregs that have been discarded or only explained by reputation can be used as plant medium material. Usually, the medium used in mushroom blocks is rubber wood powder, but in this study the dust from the decay of crude palm oil dregs was used as a medium. The results show that the remains of the part of the crude palm oil dregs that rots and will eventually rot and can be used as organic fertilizer and then used as compost material for mushroom plant media. The design used in the study is the original design of the existing mushroom mound. The results of the study concluded that crude palm oil dregs have physical and mechanical properties that are suitable for use as mushroom plant medium.
