Abstract

Increasing human needs cause an increase in production on an industrial scale and can have an impact on increasing contamination of the aquatic environment. Efforts to improve water quality can be made by removing contaminants using renewable activated carbon originating from agricultural waste such as rice husks and teak sawdust. This research aims to examine the adsorption capacity of activated carbon from rice husks (RHAC) and teak sawdust (TSAC) on a binary mixture of Fe(II)/Cu(II) as well as the level of selectivity of each adsorbent on Fe(II) and Cu(II) ions. RHAC and TSAC activated carbon are produced through carbonization processes (T=400 °C, t=60 minutes), reflux (NaOH 2N, T=100 °C, t=120 minutes), chemical activation using H3PO4 (30%, 1:3, b/b) and physics (furnace). The results of this research are that RHAC and TSAC activated carbon have the functional groups O-H (str), C-H (str), C≡C, C=C, C-O (str), and C-O-P (str). The surface character of RHAC and TSAC activated carbon is dominated by the elements C, O, and P. The results of the Fe(II) and Cu(II) ion adsorption treatment using RHAC and TSAC activated carbon follow PSO kinetic modeling with R2 values of 0.9221 and 0.9565 on RHAC and 0.9915 and 0.97 on TSAC. TSAC-activated carbon more selectively adsorbs Fe(II) and Cu(II) ions compared to RHAC-activated carbon with adsorption percentages reaching 97.34% and 87.82%, respectively.

Abstract

Desa Sumberagung, Kecamatan Pracimantoro, Kabupaten Wonogiri menghadapi tantangan keterbatasan ekonomi akibat ketergantungan pada penjualan singkong dalam bentuk mentah atau gaplek dengan nilai jual rendah. Program pengabdian kepada masyarakat ini bertujuan untuk memberdayakan Gapoktan Sumberagung melalui penerapan teknologi fermentasi pada singkong dan kulit singkong sehingga menghasilkan produk inovatif berupa FERKUSI (tepung fermentasi kulit singkong) dan MOCAF RED (modified cassava flour berwarna merah). Metode pelaksanaan meliputi sosialisasi, pelatihan, penerapan teknologi, serta penyusunan strategi keberlanjutan dengan melibatkan dosen, mahasiswa, pemerintah desa, dan mitra masyarakat. Hasil kegiatan menunjukkan peningkatan keterampilan masyarakat dalam produksi tepung fermentasi, serta terbentuknya jejaring distribusi melalui BUMDes dan mitra pemasaran lokal. Program ini berkontribusi terhadap peningkatan ekonomi lokal, ketahanan pangan, dan kesehatan masyarakat, serta mendukung pencapaian IKU perguruan tinggi, SDGs (2, 3, dan 12), dan Asta Cita (3 dan 6).
