Pemanfaatan Limbah Baglog Cendawan Tiram (Pleurotus ostreatus) Menjadi Biofoam

Abstract

Penggunaan styrofoam yang sulit terurai mendorong pengembangan biofoam ramah lingkungan. Penelitian ini mengkaji pemanfaatan miselium Pleurotus ostreatus yang dikombinasikan dengan pati, PVA, dan magnesium stearat sebagai bahan alternatif. Biofoam dibuat melalui proses pencampuran dan pengepresan, kemudian diuji kekuatan mekanik, daya serap air, dan biodegradabilitasnya. Hasil penelitian menunjukkan bahwa formulasi berbasis pati–miselium memiliki kekuatan mekanik lebih rendah dibandingkan styrofoam, namun penambahan PVA dan magnesium stearat meningkatkan kerapatan dan kestabilan struktur. Ketahanan air meningkat dan proses degradasi tanah berlangsung lebih cepat pada formulasi tersebut. Penelitian ini menunjukkan bahwa biofoam berbahan pati, miselium, PVA, dan magnesium stearat memiliki potensi sebagai pengganti styrofoam dengan karakter lebih ramah lingkungan.

The persistence of non-degradable styrofoam has driven the development of more environmentally friendly biofoam materials. This study examines the use of Pleurotus ostreatus mycelium combined with starch, PVA, and magnesium stearate as an alternative material. The biofoam was produced through mixing and hot-pressing processes, followed by tests of mechanical strength, water absorption, and biodegradability. The results showed that starch–mycelium formulations exhibited lower mechanical strength than styrofoam; however, the addition of PVA and magnesium stearate improved structural density and stability. Water resistance increased, and soil degradation occurred more rapidly in the modified formulation. This study demonstrates that biofoam made from starch, mycelium, PVA, and magnesium stearate has potential as an environmentally friendly replacement for Styrofoam.
