Calotropis gigantea stems (CGS) has the potential to use as biosorbent for adsorption of Cu(II) ions. In this study, the CGS biosorbent (CGSB) was prepared by drying and grounding. The effect of independent variables on adsorption capacity were investigat... see more

The use of a low-cost biosorbent prepared from Ipomoea pes-caprae stem for the adsorption of Cd(II) ions from aqueous solution at different contact times, biosorbent sizes, pH values, and initial Cd(II) ions concentration solution was investigated. The bi... see more

Corn stalks are an agricultural waste that is commonly found in Indonesia. Corn stalks have a high enough cellulose content which has functional groups that can be used as biosorbents. This study aims to optimize the adsorption of corn stalk waste to merc... see more

Seiring perkembangan industri di Indonesia, maka pencemaran oleh industri pun mengalami peningkatan secara tajam. Bahan pencemar dapat berupa bahan mikrobiologi maupun kimia. Penelitian Ini bertujuan Untuk mengatahui pengaruh konsentrasi ekstrak kulit bua... see more

Minyak goreng yang telah digunakan beberapa kali mengolah bahan pangan akan bersifat toksik apabila digunakan secara terus menerus dalam waktu jangka panjang, sehingga diperlukan zat yang dapat mengadsorpsi senyawa toksik tersebut. Kandungan selulosa yang... see more
