Abstract

Kegiatan pengabdian kepada masyarakat ini bertujuan untuk meningkatkanpemahaman/pengetahuan masyarakat tentang banyaknya manfaat yang dikandungdaun sirih dan tanaman jahe sebagai salah satu kekayaan alam Indonesia. Daunsirih dalam kegiatan ini digunakan untuk membuat hand sanitizer alami. Selainpembuatan hand sanitizer alami dalam kegiatan ini juga mengajarkan masyarakatuntuk mengolah tanaman obat keluarga, salah satunya jahe sebagai minumanyang dapat meningkatkan imunitas tubuh. Kegiatan pengabdian masyarakat inidilakukan dalam bentuk sosialisasi terhadap masyarakat di Kelurahan Taba AnyarRT 001, Kecamatan Lebong Selatan, Kabupaten Lebong, Bengkulu denganmendatangi rumah-rumah warga dan mendatangi pasar. Metode kegiatan yangdigunakan berupa sosialisasi, ceramah tentang materi berikut praktik pembuatanhand sanitizer dan pengolahan Tanaman Obat Keluarga (TOGA) menjadi serbukdan minuman siap saji. Hasil dari pengabdian masyarakat ini adalah pemahamanpeserta tentang pembuatan hand sanitizer dari bahan alami beserta fungsinya danpengolahan minuman dari tanaman obat keluarga salah satunya jahe.

Abstract

This study evaluates the adsorption performance of NaOH-activated cassava peel biochar (Manihot esculenta Crantz) for the removal of Pb²⁺ ions from aqueous solutions, with particular focus on the effects of solution pH and contact time. Cassava peel biochar was produced via pyrolysis at 180–350 °C and chemically activated using 0.1 M NaOH. Surface functional groups and morphology were characterized using Fourier Transform Infrared Spectroscopy (FTIR) and Scanning Electron Microscopy–Energy Dispersive X-ray (SEM–EDX). Batch adsorption experiments were conducted by varying solution pH (3–8) and contact time (30–120 min), while Pb²⁺ concentrations before and after adsorption were analyzed using Atomic Absorption Spectroscopy (AAS). The results showed that solution pH significantly affected Pb²⁺ adsorption, with the highest adsorption capacity of 9.94 mg/g achieved at pH 5. Contact time also influenced adsorption performance, and the optimum condition was obtained at 90 min, yielding a maximum adsorption capacity of 9.94 mg/g. These findings indicate that NaOH-activated cassava peel biochar exhibits stable and effective Pb²⁺ adsorption under slightly acidic conditions and moderate contact time, highlighting its potential as a low-cost and environmentally friendly adsorbent for Pb²⁺ removal from contaminated wastewater.
