Abstract

Desa Muara Penimbung terletak di Kecamatan Indralaya Utara, Kabupaten Ogan Ilir, Sumatera Selatan. Mayoritas penduduk di Desa ini merupakan petani. Masyarakat seringkali menghadapi masalah pengelolaan limbah organik dan penggunaan bahan kimia berbahaya untuk pertanian. Solusi ramah lingkungan mengatasi permasalahan ini adalah memanfaatkan sampah organik sebagai bahan baku eco-enzyme. Eco-enzyme merupakan larutan yang berasal dari zat organik kompleks dari proses fermentasi campuran antara limbah organik seperti kulit buah, sayuran, gula merah, dan air. Eco-enzyme dapat dimanfaatkan menjadi pestisida dan pupuk organik. Penggunaan eco-enzyme sebagai pestisida dan pupuk organik mengurangi risiko paparan terhadap bahan kimia berbahaya bagi petani dan lingkungan. Desa Muara Penimbung memiliki potensi besar menghasilkan limbah organik dari perkebunan dan rumah tangga, tetapi kesadaran dan pengetahuan masyarakat dalam pengelolaan sampah organik masih rendah. Tujuan diadakannya kegiatan ini yaitu untuk mengintegrasi pengelolaan eco-enzyme dalam pemanfaatannya mengolah sampah sayur dan buah-buahan menjadi pestisida dan pupuk organik bagi perkebunan di Desa Muara Penimbung. Metode yang digunakan yaitu metode eksperimen. Variabel penelitian yang dilakukan adalah jumlah limbah sayuran dan kulit buah, ragi, dan larutan gula merah dan aquadest, dengan rasio limbah kulit buah dan sayur 7:3. Pengujian secara langsung menunjukkan bahwa penggunaan pupuk meningkatkan pertumbuhan tanaman cabai hingga 7 cm pada hari ke-3. Penggunaan pestisida memerlukan evaluasi lebih lanjut karena serangga mati dalam waktu lama setelah penyemprotan. Program ini membantu mengintegrasikan permasalahan sampah perkebunan seperti sayur dan kulit buah di Desa Muara Penimbung. Respons dari masyarakat positif dan tertarik untuk melanjutkan program serupa di masa depan.

Abstract

Heavy metal pollution such as Cu²⁺, Fe³⁺, and Pb²⁺ metal ions resulting from industrial and laboratory activities has become a serious environmental issue due to their toxic and bio-accumulative nature. This study aims to evaluate the adsorption effectiveness of natural bentonite and bentonite activated chemically with H₂SO₄ followed by thermal treatment at 300 °C. The activation process was intended to enhance surface area, porosity, and the number of active sites on the bentonite surface. Adsorption experiments were conducted using synthetic wastewater containing Cu, Fe, and Pb metal ions with varying adsorbent masses (1–5 grams), and surface morphology characterization was performed using SEM-EDX. Results showed that acid-thermal activated bentonite had a more porous and fragmented surface structure compared to natural bentonite, contributing to higher adsorption efficiency. At an adsorbent mass of 5 g, Pb removal reached 92.5% with acid-thermal activated bentonite, whereas natural bentonite achieved only 85.5%. Additionally, the removal efficiency of Fe³⁺ and Cu²⁺ ions also significantly increased after activation. These findings indicate that chemical and thermal activation synergistically enhance the performance of bentonite as an effective adsorbent for treating hazardous wastewater containing heavy metals.

Abstract

Metal solid waste from coal combustion (fly ash) is abundant in Indonesia, as an effective and economical adsorbent in neutralizing acid mine drainage (AMD). Given that the continuous utilization of coal produces environmental challenges in the form of AMD containing acid residues and heavy metals such as manganese (Mn), an appropriate treatment solution is required. The adsorption method was chosen due to its simplicity, cost effectiveness, and ability to remove heavy metal pollutants. The purpose of this research is to characterize fly ash before and after heating by SEM and XRD analysis, and evaluate the effect of fly ash physical activation temperature by heating at 100oC and 200oC for an interval of 60 minutes on the characteristics and adsorption ability of fly ash. In addition, this study also evaluated the effectiveness of the adsorbent mass (fly ash before heating and after heating) in increasing pH and reducing Mn concentration in AMD so that it meets the quality standards of Class 1 river water. The results obtained from this study show a fundamental difference in the properties of fly ash before and after heating. Based on BET analysis, the physical activation process resulted in pore enlargement (0.196 nm) and increased surface area of the adsorbent (0.847 m2/g), which significantly affected its binding capacity to solutes (adsorption capacity). The application of fly ash as an adsorbent showed the ability to increase the pH value of acid mine drainage towards neutral conditions. The process of reducing heavy metal ions Mn by using 50 g of fly ash heating at 100oC and 200oC, resulted in a removal percentage of 94.74% and 98.44%. It is hoped that this research can provide innovative and sustainable AMD treatment and increase the use value of fly ash waste.

Abstract

The combustion of coal in power plants (PLTU) generates fly ash containing silica dioxide (SiO?) and alumina (Al?O?), which exhibit promising properties as adsorptive materials. Fly ash, typically regarded as an industrial by-product, has been widely explored for its application as an adsorbent in wastewater purification. One of the most challenging wastewaters is acid mine drainage, characterized by strong acidity (pH < 5), residual contaminants, and elevated concentrations of heavy metal ions such as manganese (Mn) and iron (Fe). When released untreated, this effluent poses significant risks to both surface and groundwater quality in mining areas. This study focuses on the characterization and utilization of fly ash as an adsorbent to neutralize acidity and reduce Mn and Fe concentrations in acid mine drainage. The material was characterized using SEM-EDX and XRD techniques, followed by adsorption experiments. To enhance its properties, fly ash underwent physical activation through heating at 100 °C for 60 minutes. The activation process modified its structure, expanding pore volume and increasing surface area, thereby improving adsorption performance. The experimental results revealed significant differences in the properties of fly ash before and after activation. Activated fly ash effectively raised the pH of acid mine drainage to near-neutral conditions while achieving removal efficiencies of 96.61% for Mn and 83.33% for Fe using 50 g of adsorbent. These findings highlight the potential of fly ash as a low-cost and effective material for acid mine drainage treatment, both for acidity control and heavy metal removal.
