The Utilization of Palm Oil Wastes in the Form of Empty Fruit Bunch and Mesocarp Fiber as Potential Oyster Mushroom (Pleurotus Ostreatus) Growing Media

---

Indonesia is the leading producer of palm oil that fulfills more than half of the world's palm
oil demand. The large scale operation in palm oil agroindustry is economically beneficial which
improves life quality and income for many Indonesians, however it has also brought a massive
amount of byproducts that if not treated properly would damage the environment. Empty fruit
bunch and mesocarp fiber are two of the least used palm oil mill byproducts that’s usually removed
by incineration. In this internship, the trial of utilizing both empty fruit bunch and mesocarp fiber as
the media for oyster mushrooms (Pleurotus ostreatus) was performed. The substrate tested included
rubber wood dust, empty fruit bunch, mesocarp fiber, a combination of rubber wood dust and
mesocarp fiber, and a combination of rubber wood dust and empty fruit bunch. The substrate was
mixed with nitrogen and calcium supplementation and sterilized to ensure sterile and nutritious
media for the mushroom to grow. Each substrate was then inoculated with mushroom spawn and
kept in a 25-34oC grow room until fully grown, while being sprayed consistently three times a day to
ensure enough humidity. All substrates that contained palm oil by products could produce successful
mushroom growth with various harvest time and biological efficiency. However, the growth condition
for the mushroom in this experiment was non-optimal, thus future experiment with optimum
conditions should be performed to truly uncover each substrate potential as oyster mushrooms
growth media.
