Abstract

Acid mine drainage (AMD) is formed because rocks containing sulfide minerals, such as pyrite (FeS?), are exposed to oxygen and water. AMD treatment is generally carried out with lime, but this method is relatively expensive and unsustainable. Fly ash-bottom ash (FABA), a type of coal combustion waste can potentially replace lime in treating acid mine drainage (AMD). This study aimed to elucidate the potential use of FABA to neutralize pH of AMD. The method used was a floating FABA system using styrofoam with three treatments: floating FABA with dimensions (cm length x cm width x cm height) of 33x33x8 (F1 30), floating FABA of 28x28x8 (F2 25), and floating FABA of 23x23x8 (F3 20). The floating FABA consisted of 85% FABA and 15% cement, with a 120 L AMD. The results showed that the F1 30 treatment reached a pH of 6.06 from an initial pH of 4.2 within 3 days. The floating FABA application also reduced the concentration of heavy metals (Fe and Mn) and total suspended solids (TSS) in the F2 25 treatment. Micro XRF analysis indicated a high element distribution in the floating treatment zone, supporting the neutralization mechanism of precipitation and adsorption. The results of the statistical analysis showed no significant difference between treatments, indicating that all treatments were effective and could be considered based on cost efficiency and retention time. Overall, the floating FABA application increased pH and progressively reduced heavy metal content, supporting its use as an efficient and sustainable AMD neutralization solution.

Abstract

Oil-based soil pollution is a pressing global environmental issue and has serious impacts on ecosystems and human health. Hydrocarbon compounds, especially heavy fractions, are persistent and difficult to decompose naturally in a short time, thus requiring intervention to accelerate the environmental recovery process. This research focuses on developing strategies to increase the effectiveness of oil-contaminated soil degradation. The development of a palm oil-based oil spill dispersant (Bio-OSD) combined with bacterial endospores of Bacillus pseudomycoides RAY21 offers an innovative approach to bioremediation. This particular bacterial endospore was selected for its capacity to sustain the viability of a potent biological agent until the point of application. The bacterial growth process was monitored to determine the optimal harvesting time by measuring optical density (OD600) at hourly intervals using a spectrophotometer until the stationary phase was reached. Following the harvesting of bacterial cells, various stressors were applied to stimulate sporulation, which included high-temperature incubation (80°C), nutrient deprivation, and their synergistic combination. The efficacy of the sporulation process was validated through endospore staining with malachite green. The resultant endospore pellets were integrated into the Bio-OSD and subjected to viability assessments every three days over a 24-day period using the Total Plate Count (TPC) method. The biodegradative capacity of the Bio-OSD containing endospores was evaluated through the analysis of Total Petroleum Hydrocarbon (TPH) degradation in artificially contaminated soils (3%) across a 28-day incubation. Findings indicated that optimal bacterial cell production occurred in Nutrient Broth, with peak harvesting at 40 hours. Moreover, the most effective sporulation was attained under combined stress conditions specifically, exposure to high temperature (80 °C for 24 hours) concomitant with nutrient deprivation (NaCl 0,85%) as demonstrated by the presence of green-stained endospores. This study provides evidence that Bio-OSD functions effectively as a stable carrier medium for bacterial endospores over a period of up to 24 days. The Bio-OSD formulation incorporating Bacillus pseudomycoides RAY21 endospores demonstrated the capability to degrade 78% of Total Petroleum Hydrocarbons (TPH) in petroleum-contaminated soil after 28 days of incubation. This degradation efficiency was significantly superior to that of the control treatment, which achieved a mere 32% degradation under the same laboratory conditions. To enhance the understanding and application of this approach, further investigations are recommended to be conducted on a larger scale, along with optimization analyses, to facilitate the development of more sustainable environmental remediation.

Abstract

The agricultural sector plays a strategic role in improving economic sustainability and responding to environmental challenges. A sustainable agricultural approach based on the integration of coffee and dairy cattle is a potential solution to these challenges. This study aims to analyze financial feasibility by comparing two types of coffee and dairy cattle integration farming systems, namelytype 1 (existing coffee-dairy cattle integration) and type 2 (improved integration). The difference between the two types lies in the connectivity of input and output use in the integration system. The method used is financial feasibility analysis with investment criteria indicators in the form of NPV, IRR, Net B/C, and payback period. The research was conducted in Boyolali Regency. The resultsof the financial feasibility analysis show that the improved coffee and dairy cow integration type (type 2) is financially superior to type 1, with an NPV of IDR 1,714,402,922.83 and an IRR of 22%, far exceeding type 1 (IRR of 16%), with a payback period of 6 years and 8 months. This financial benefit came from lower costs for feed, energy, and fertilizer, as well as big economic gains from diversifyingproducts that came from making better use of waste. Using biodigester technology to turn biomass into energy is another way to cut down on greenhouse gas emissions from manure waste. These findings provide a strong basis for encouraging the implementation of improved coffee and dairy cow integration through a series of fiscal incentive policies and farmer assistance.

Abstract

Air asam tambang (AAT) merupakan salah satu masalah yang ditimbulkan akibat kegiatan pertambangan. Air asam tambang terbentuk sebagai hasil oksidasi mineral sulfida yang tersingkap ke permukaan oleh air dan oksigen. Alternatif pengelolaan AAT secara berkelanjutan dan ramah lingkungan yaitu dengan membuat konstruksi wetland. Tujuan penelitian ini adalah untuk mendapatkan jenis dan komposisi bahan organik potensial yang mampu meningkatkan kualitas AAT. Penelitian ini terdiri dari tiga tahapan penelitian yang dilakukan secara bertahap, yaitu screening jenis bahan organik, kombinasi dua jenis bahan organik yang berbeda, dan kombinasi pupuk kandang sapi dan tandan kosong kelapa sawit pada berbagai komposisi. Jenis bahan organik yang digunakan yaitu pupuk kandang sapi, pupuk kandang kambing, pupuk kandang ayam, tiga jenis pupuk kompos, tandan kosong kelapa sawit, serbuk gergajian kayu, chip kayu, cacahan eceng gondok, cocopeat, limbah segar daun kayu putih, limbah kompos daun kayu putih, limbah penyulingan sereh wangi, limbah baglog jamur, dan ampas tebu. Hasil penelitian menunjukkan bahwa terdapat beberapa jenis bahan organik yang dapat meningkatkan pH AAT. Kombinasi tandan kosong kelapa sawit dan pupuk kandang sapi dengan perbandingan 2:1 menjadi pilihan yang tepat karena mampu meningkatkan pH dan menurunkan logam berat dan sulfat terlarut serta ketersediaan bahan baku yang melimpah di alam, khususnya di Indonesia.
