The trend of using animal skin as a raw material continues to increase globally, but sustainable use has negative impacts on the environment, health, and society. Therefore, there is a need for environmentally friendly alternatives with good characteristics. Phylum Basidiomycota, such as Ganoderma lucidum, is one of the potential alternatives for producing fungal-based biomaterials due to its natural adhesive properties and ability to degrade lignocellulose. However, the production process of fungal-based biomaterials still faces several challenges, such as slow mycelium growth or high contamination rates. Therefore, this research aims to optimize the production of G. lucidum mycelium on solid medium using variations in the addition of sengon wood sawdust and empty oil palm fruit bunches for fungal-based biomaterial production. This study was conducted using an experimental method with a completely randomized design consisting of three stages, a total of 13 variations, and three replications. The observed parameters were mycelium growth ratio, mycelium growth rate, and loss of organic matter. The culture age used as the inoculum was 8 days, incubated at a temperature of 25°C. The mycelium growth of G. lucidum in the medium with a 25% addition of sengon wood sawdust showed the best results. The mycelium growth of G. lucidum in the medium with a 50% addition of oil palm empty fruit bunch showed the best results. The use of sengon wood sawdust and oil palm empty fruit bunch can be considered as alternative raw materials for fungi-based biomaterial production.
