Potensi Jamur Makro Isolat Lokal Riau Dalam Produksi Kulit Berbasis Miselium
Leather is an important commodity used in various products such as clothing, footwear, furniture, and accessories. However, the production of leather derived from animals and synthetic leather has a negative impact on the environment. One more environmentally friendly alternative with a short production time is leather made from fungal mycelium. This is supported by the high biodiversity of macro fungi in Indonesia. This study aims to select local macrofungus isolates with potential for use as mycelium-based leather through production methods on liquid media and with the addition of fabric. The isolates were tested to determine their growth rate on YPMA medium. Out of 7 fungal isolates, 4 best isolates were selected: Ganoderma sp AP11, T. versicolor AS8, P. ostreatus AP12, and T. gibbosa AP5. The selected isolates were used for leather production on liquid medium with the addition of fabric, incubated for 8 weeks. The results of the study showed that these isolates have the potential to produce mycelium-based leather. Ganoderma sp AP11 exhibited the highest growth rate of 24.71 mm/day. In liquid production, Ganoderma sp AP11 had the highest dry weight of mycelium sheets at 0.4381 g. In production with the addition of cloth, T. gibbosa AP5 had the highest dry weight at 0.7936 g. The density of the mycelium sheet in liquid medium showed that T. gibbosa AP5 had the highest density value of 0.2753 g/cm³, and the density of the mycelium sheet in production with the addition of cloth showed that P. ostreatus AP12 had the highest density of 0.7603 g/cm³.
