“…In this study, the highest adsorption capacity obtained was 0.644 mg/g. However, this result is smaller than the previous study by [30], which obtained an adsorption capacity of 1.44 mg/g, which in this study used a solution of Fe (II) with an initial concentration of 50 mg/L. could be associated with cellulose, hemicellulose, or lignin polymers [21].…”

<p>The present study used adsorbents from Kepok banana peel to remove Fe (II) from an aqueous solution. The effect of adsorbent dose and initial metal concentration was investigated at room temperature to evaluate the maximum adsorption and adsorption capacity of Kepok banana peels. The adsorption parameters studied were adsorbent mass [0.5-2.5 g], and initial Fe (II) concentration [30-70 mg/L], where the operating conditions were 50 ml of Fe metal solution was added to each adsorbent, the pH value of the mixture was adjusted to 6. Then the mixture was stirred at 250 rpm for 30 minutes. In the adsorption process, it was found that 2.5 grams of mass adsorbent and 60 mg/L as initial metal concentration gave the highest adsorption and adsorption capacity, with 57.99% and 0.644 mg/g, respectively. FTIR spectra of adsorbent showed hydroxyl, carboxylic, and amine groups in Kepok banana peels. This study showed that Kepok banana peels had good potential for removing Fe (II) ions and could be used as a good adsorbent for removing the Fe (II) from water and wastewater at very little concentration.</p>

“…Selanjutnya pada pH 4 sampai 6 penyerapan ion Pb 2+ menurun, dikarenakan pada pH tinggi sisi aktif adsorben menjadi deaktif sebab reaksi antara ion logam yang bermuatan positif dengan ion OH -. Tidak hanya itu pada pH yang lebih tinggi, terbentuk kompleks hidroksilasi yang larut dari ion logam yang berkompetisi dengan situs aktif adsorben [18].…”

“…Tolakan antara ion logam dan adsorben terjadi karena permukaan adsorben bermuatan positif sehingga ion H + dari HNO3 yang terdapat dalam larutan lebih banyak sehingga ion Pb 2+ akan berkompetisi dengan proton untuk menempati sisi aktif pada adsorben sehingga penyerapan ion Pb 2+ berkurang.Selanjutnya pada pH 4 sampai 6 penyerapan ion Pb 2+ menurun, dikarenakan pada pH tinggi sisi aktif adsorben menjadi deaktif sebab reaksi antara ion logam yang bermuatan positif dengan ion OH -.

Adsorption is the process of accumulation of atoms or ions in solution on the surface of a solid adsorbent. Silica gel can be used as an adsorbent because it has two groups of active sites, namely silanol (Si-OH) and siloxane (Si-O-Si). The active groups also allow silica to be modified. This modification was made to increase the ability of silica to adsorb ions, one of which is Pb 2+ ion. The modifier compound used is a sulfonic salt (4-amino-5-hydroxy-2,7-naphthalenedisulfonic acid) with a glysidoxypropyltrimethoxysilane (GPTMS) linking compound. The modified adsorbents were characterized by FTIR and the absorption results were characterized by AAS. The modified adsorbent was to determine the optimum conditions for adsorption of Pb 2+ ions using silica sulfonate. Adsorption was carried out using the batch method. The optimum absorption conditions for Pb 2+ metal ions using silica sulfonate were obtained at pH 3, contact time of 45 minutes.

“…Di lingkungan, logam berat terakumulasi di tanah dan air yang pada akhirnya akan berdampak pada kontaminasi makanan yang dikonsumsi manusia (Arunakumara, Walpola, & Yoon, 2013;Suliestyah, Hartami, & Tuheteru, 2020). Kebutuhan air yang dapat digunakan untuk keperluan sehari-hari meningkat seiring dengan pertumbuhan populasi, sehingga penggunaan dan pengolahan kembali limbah industri menjadi alternatif yang akan diupayakan untuk memenuhi kebutuhan pasokan air (Arifiyana & Devianti, 2020).…”

Contamination in aquatic systems has an indirect impact on survival. One type of contamination of the aquatic system is the presence of heavy metal contamination. Continuous exposure to heavy metals can cause kidney, liver, neurological disease, vascular disease, and cancer. Sources of heavy metals come from the mining industry, paint industry, use of pesticides, etc. To provide insight to the public, it is necessary to conduct education about the sources of heavy metal contamination and its impact on the body. The implementation of this community service activity is in the form of webinars for active students. A total of 63 students participated in this educational activity. The selection of students as the target community is based on their role in society. The methods used in this activity include presentations by lecturers and students, as well as discussions and questions and answers. To measure knowledge, pre-test and post-test were conducted.
