Abstract

Illegal gold mining caused various environmental damages in the world. Indonesia is one of the countries with abundant mineral reserves, especially Jambi Province. Jambi has much of natural resources, such as coal and gold. Unfortunately, the management of these natural resources has not been appropriately managed, which has resulted in much illegal gold mining. Illegal mining activities have caused environmental damage, mainly decreased water quality and changed landscapes. This paper explains the illegal mining activities at Jambi Province, including its history, socio-economic and environmental impacts, as well as recent technologies to reduce the environmental damage. Quantitative and qualitative methods were used in this research, including interviews, questionnaires, and laboratory measurements. The results showed that the people of Sarolangun, Bungo, and Tebo were aware that their illegal gold mining activities caused environmental damage. However, economic conditions and insufficient employment opportunities made unlawful gold miners have no other choice. Illegal gold mining activities have also shifted people's livelihoods who previously worked as farmers.

Abstract

Mercury is a hazardous element because of its toxicity and harmful effects on human health. Various traditional and low-cost methods have been developed to remove mercury from wastewater. This study used local raw material as an alternative adsorbent to treat mercury-contaminated wastewater. Activated bentonite was prepared using different chemical activators (H3PO4, HCl, and ZnCl2) in various concentrations. Then, it was dried at 200C for an hour. The materials were characterized by SEM-EDS. Its percent removal and isotherm models were analyzed. In this study, the most effective activator was H3PO4 and the experimental data matched the Freundlich model.

Abstract

Acid mine drainage (AMD) is a highly dangerous form of water pollution results from coal mining activities. AMD is characterized by its high concentration of heavy metals and low pH levels, which have been linked to various health problems, including skin disease, cancer, and poisoning. This paper presents a comprehensive review of the available information on the AMD and its alternative low-cost treatment methods. One such method is adsorption, an eco-friendly and cost-effective approach to treating the AMD. This review draws on 99 published papers as the sources that provide a comprehensive overview of the AMD sources and problems worldwide. This study explores the potential of conventional materials, such as activated carbon, biochar, and other materials for treating the AMD. A special section on conventional materials is well-detailed and provides valuable insights into their effectiveness. It is essential to explore the alternative treatment methods that are both environmentally friendly and cost-effective. This review provides valuable insights in this regard. By using the low-cost and sustainable methods, we can effectively treat AMD and reduce its impact on the environment and human health.

Abstract

This study focuses on the impact of goat manure and rice husk charcoal distribution on oil palm cultivation in former mining lands. The objective is to determine the optimal combination of goat manure and rice husk charcoal that enhances the growth of oil palm plants on these lands. Conducted in Pijoan Village, Muaro Jambi District, Jambi Province in 2021, the research utilized a completely randomized block design with 8 treatments and 3 repetitions, yielding 24 experimental units. The eight treatments consisted of varying ratios of goat manure to rice husk charcoal: (P1) 150 g goat manure + 325 g rice husk charcoal per planting hole, through (P8) 325 g goat manure + 150 g rice husk charcoal per planting hole. Results indicated that the combination of 325 g goat manure + 150 g rice husk charcoal (P8) provided the best outcomes in plant height, stem diameter, leaf balance at the third frond, and total frond count on reclaimed land.

Abstract

This study investigates the impact of thermophilic anaerobic digestion on biogas production and methane emission reduction from Palm Oil Mill Effluent (POME). Conducted under controlled conditions at 55°C and 65°C, the research aims to optimize biogas yield and reduce Chemical Oxygen Demand (COD) levels. The findings indicate that thermophilic digestion at 65°C significantly enhances biogas production, yielding 1.81 L Biogas per liter of POME over an 8-day period, compared to mesophilic conditions. Furthermore, the study demonstrates substantial COD reduction, supporting a more efficient and environmentally friendly process. By capturing methane emissions and converting them into a renewable energy source, this method aligns with global climate policies and greenhouse gas reduction targets. The integration of thermophilic anaerobic digestion into POME treatment presents a viable solution for the palm oil industry to improve waste management practices and contribute to sustainable development goals. Future research should explore large-scale implementations to maximize the environmental and economic benefits of this technology.

Abstract

This study presents the development and application of an innovative 3-in-1 nanotechnology pyrolysis reactor designed to simultaneously produce liquid smoke, activated carbon, and limestone from locally sourced raw materials in Jambi Province, Indonesia. The multifunctional reactor combines three production processes, which are traditionally performed separately, into a single, efficient unit, addressing both economic and environmental challenges. Coal serves as the primary heat source and material for activated carbon, whereas shell waste is calcined to produce limestone. The reactor operates at temperatures exceeding 550°C to ensure optimal conversion, with a glass wool insulator replacing clay to enhance thermal efficiency. The liquid smoke undergoes further distillation to achieve purification, while residual activated carbon is chemically activated with H₃PO₄ to enhance its adsorption capacity. The experimental results demonstrate that this reactor can produce high-quality products with minimal resource wastage. This 3-in-1 pyrolysis reactor represents a sustainable, cost-effective solution for resource-limited settings, with broad potential for application in waste-to-product conversion, environmental remediation, and rural development.

Abstract

Environmental pollution from wastewater and soil contamination remains a critical global concern, with current treatment methods often facing limitations in scalability, cost, or environmental safety. Biochar, a carbon-rich material derived from biomass pyrolysis, has emerged as a sustainable adsorbent for heavy metals and organic pollutants. While its use in environmental remediation is well-established, the fate and reuse of spent biochar have received limited attention. This comprehensive review explores the untapped potential of used biochar, particularly for the removal of hexavalent chromium (Cr(VI)) from wastewater and its role in enhancing soil fertility. We critically analyze current practices, mechanisms of Cr(VI) removal using spent biochar, regeneration techniques, and field applications, while highlighting circular economy frameworks that promote resource efficiency. The study integrates empirical evidence from recent case studies and offers policy recommendations to support large-scale implementation. This work is the first to provide an integrative review of the reuse of spent biochar with a dual focus on wastewater treatment and soil enhancement, underpinned by a circular economy perspective. It addresses critical research gaps by evaluating regeneration techniques, post-use functionality, and practical field applications, thereby positioning spent biochar as a viable, low-cost, and eco-friendly alternative in environmental management systems.
