Abstract

Soil contamination by the heavy metal lead (Pb) poses a significant threat to public health and ecosystems. This study evaluated the effectiveness of the ex-situ biopile method for remediating Pb-contaminated soil at the Kawatuna Landfill, Palu City. Soil samples were collected from the contaminated site and treated in a biopile prototype with controlled aeration and moisture, with the addition of compost as an amendment at 10% (w/w). Laboratory analyses conducted at the Integrated Laboratory of Tadulako University showed a decrease in total Pb concentration from 41.96 mg/kg to 31.83 mg/kg after seven days of treatment. This corresponds to a removal efficiency of 24.13% and an average degradation rate of 1.45 mg/kg·day. These results indicate that the biopile method is capable of reducing Pb concentrations in soil during the initial stage of treatment; however, optimization of treatment duration and operational conditions is required to achieve regulatory soil quality standards. Furthermore, the use of locally sourced compost as a nutrient amendment and the absence of secondary waste generation support the biopile method as an environmentally friendly and cost-effective soil remediation technology.

Abstract

The home-based tempeh industry faces serious challenges in managing liquid waste containing pollutants such as Total Suspended Solid (TSS), ammonia, turbidity, and pH that exceed quality standards. This study aims to determine the decrease in pollutant levels in tempeh industry liquid waste with a combination of coffee grounds and rice husk adsorbents, and to determine the effect of giving variations in adsorbent mass on the value of pollutant parameters in tempeh industry liquid waste. The method used was quantitative experimental with waste samples from Monas Tempe Factory. The adsorbent mass variations tested were 1:1, 1:2, and 2:1, with a total dose of 8 grams per 500 ml of waste, and the adsorption process was carried out with magnetic stirring for 30 minutes at 300 rpm. The results showed that the adsorbent combination was effective in reducing TSS and ammonia, with the highest TSS reduction reaching 53.42% and ammonia 67.33% in the 1:2 variation. The maximum adsorption capacity for TSS was 4330 mg/g and for ammonia 127.50 mg/g. However, this treatment also caused an increase in turbidity (-19937.50%) and pH (-16.88%). The Freundlich isotherm model is more suitable to explain the adsorption process, indicating that adsorption is favorable and occurs physically with multilayer. Although this combination was effective in reducing TSS and ammonia, there were limitations in dealing with turbidity and pH.

Abstract

Domestic wastewater treatment often faces challenges due to high concentrations of organic matter and dissolved solids that can pollute the environment if left untreated. This study aims to evaluate the performance of a honeycomb biofilter in reducing key wastewater pollutants. The method applied was a laboratory-scale experiment using a small-scale WWTP system equipped with a honeycomb biofilter unit. The treatment results showed a significant reduction of BOD from 56 mg/L to 4.15 mg/L (92% efficiency), COD from 224 mg/L to 5 mg/L (97% efficiency), and TDS from 290 mg/L to 194 mg/L (30% efficiency). All parameters meet the quality standards. However, pH decreased from 7.4 to 4.4 (40% reduction), indicating the need for a pH adjustment unit before final discharge. In conclusion, the honeycomb biofilter proved effective in reducing organic load and dissolved solids, although integration with a pH neutralization unit is required to comply with environmental standards.
