Potensi Spent Mushroom Substrate (Sms) Coprinus Comatus Sebagai Green Biosorben Pada Penyisihan Logam Cu Dan Pb

---

Spent mushroom substrate (SMS) is an organic compost medium produced from mushroom cultivation processes. Biological processing has attracted attention due to its substrate specifications and larger reactions, lower energy requirements, reduced pollution, and higher desired product yields. Processing TKS waste requires large areas of land and generates pollution, so it needs to be converted into useful materials such as mushroom growing media. The aim of this study is to determine the optimal biosorbent mass for heavy metal biosorption of Pb and Cu and to characterize the best biosorbent using tests including SEM, BET, XRD, FTIR, and lignocellulose analysis. The fixed variables used are a contact time of 30 minutes, stirring speed of 150 rpm, and a biosorbent size of 100 mesh. The variables to be tested are biosorbent mass (0.5 g, 1 g, 1.5 g). Results show that for heavy metals Pb and Cu, the highest removal capacity and efficiency were achieved with a biosorbent mass of 0.5 g, with the maximum biosorption capacities for Pb and Cu being 1160 mg/g and 1025 mg/g, respectively, and the highest efficiencies being 65% and 57%. SMS has rough, cracked, porous, and fragmented pores with a surface area of 1.4666 m²/g and a pore size of 43.1569 Å. The degree of crystallinity for Pb and Cu decreased from 5.30% to 1.89% and 4.65%, respectively. Lignocellulose testing shows lignin content of 13.93%, hemicellulose 9.25%, and cellulose 16.15%, while FTIR testing indicates the presence of hydroxyl, amino, carbonyl, and phosphate groups. The study concludes that SMS from Coprinus comatus is categorized as a good green biosorbent, but its heavy metal absorption capacity has not yet reached optimal levels.
