Abstract

Penelitian ini dilakukan untuk menguji kompos produksi BPK Bentong sebagai media penukar ion untuk mereduksi logam Pb. Diduga kandungan humus dalam kompos mampu membentuk kompleks dengan logam melalui pertukaran kation oleh gugus karboksil (-COOH). Media kompos yang digunakan adalah media yang memiliki ukuran ayakan antara 40–60 mesh. Pengukuran KTK kompos secara teoritis dilakukan dengan Ammonium Replacement. Variabel yang digunakan adalah dosis dan waktu kontak kompos yang ditinjau terhadap efisiensi penyisihan logam Pb pada proses batch dengan variasi dosis kompos: 0,2; 0,6; 0,8; 1; 1,5; 1,9 g dan variasi waktu kontak: 0,5; 1; 1,5; 1; 1,5; 1 jam. Hasil penelitian menunjukkan bahwa KTK teoritis kompos sebesar 56,61 meq/100 g. Dosis kompos optimum didapat sekitar 5 g dengan KTK 1,04 meq/100 g, sementara untuk waktu kontak didapatkan 2 jam dengan KTK 1,19 meq/100 g.

This research was conducted to test the BPK Bentong compost production as ion exchanger media in reducing lead (Pb). Its humus content was estimated to be able to perform the metal complex the cation exchange through the carboxyl active group (-COOH). The compost media that have size sieve number between 40–60 mesh was used. The CEC was theoretically measured by using ammonium replacement methods. Variable which were observed for the removal of Pb metal in batch process were doses and compost mixing time. The compost doses were 1, 3, 5, 7, 9 g/l and the variation of mixing time was 0.5, 1, 1.5, 2, 2.5, 3 hours. The result showed that the theoretically CEC was 54.61 meq/100 g. At the batch process, the optimum dose was approximately 5 g/l with the CEC of 1.04 meq/100 g, and the mixing time approximately 2 hours with the CEC of 1.19 meq/100 g.
