Abstract

The Putri Cempo landfill serves as the final disposal site for organic and inorganic waste. Waste from the landfill can dissolve and settle in river sediments, potentially accumulating heavy metals, such as iron (Fe) and manganese (Mn), which easily bind to organic matter. This study aims to determine the content of Iron (Fe) and Manganese (Mn) in rivers around the Putri Cempo landfill. The concentrations of Fe and Mn weres analyzed using atomic absorption spectrometry (AAS) according to SNI 6989.84:2019, with sediment sampling conducted in rivers around the Putri Cempo landfill. Sediment sampling in these rivers revealed Fe levels of 1519.414245 mg/L and Mn levels of 130.033 mg/L. The analysis indicated that Fe concentrations exceeded the established quality threshold, whereas Mn levels remained below it. Heavy metals like Fe and Mn negatively impact abiotic and biotic environments, including human health and agricultural productivity. Elevated heavy metal levels disrupt ecosystem balance and pose health risks, making their management crucial. Reducing heavy metals in river sediments near the landfill is essential. Remediation efforts using bioremediation and phytoremediation technologies can help mitigate these impacts. Ongoing efforts are necessary to control heavy metal contamination in river sediments, ensuring ecosystem stability and public health.

Abstract

Biodegradable bioplastics offer an environmentally friendly alternative. One type of bioplastic being developed is Polybutylene Adipate-Co-Terephthalate (PBAT), an aliphatic-aromatic polyester capable of decomposing through microbial activity. This study aimed to analyze the potential of bioplastic waste as a compost mixture ingredient and determine the optimal composition of bioplastic waste mixtures for compost production. The study utilized a Completely Randomized Design (CRD). The quality of the compost made from bioplastic waste mixtures was evaluated based on SNI 7763:2024 standards, with parameters including pH, temperature, additional substances, and chemical content, such as nitrogen (N), phosphorus (P), potassium (K), and organic carbon (C-organic). The composting process lasted 60 d, using mixtures of bioplastics and cow manure organic waste in proportions of 95:5, 90:10, 85:15, 80:20, 75:25, and 70:30, each weighing 1 kg. Some mixtures were supplemented with 30 mL of activated EM4 to accelerate decomposition, whereas the control group used only cow manure. The results indicate that the compost produced generally met the SNI 7763:2024 standards. The most effective composition was 80% organic waste, 20% bioplastic, and 30 mL EM4. This composition achieved N+P2O5+K2O levels of 2.88%, C-organic content of 30.46%, moisture content of 24.60%, and pH of 7.60.

Abstract

Processing municipal solid waste into refuse-derived fuel (RDF) is an alternative solution to the waste problem. This study determined the potential environmental impact of Sleman RDF as an energy diversification agent in the cement industry using life cycle assessment (LCA). The boundary system of this study is gate-to-grave, with a functional unit of co-firing energy requirements for the production of 1 metric ton of clinker. Two clinker co-firing scenarios were developed, involving a combination of coal and alternative fuels. The results showed that the production of 1 metric ton of clinker requires a large amount of resources and contributes significantly to climate change, ecosystem toxicity, and human toxicity. Co-firing clinker in the alternative scenario successfully reduced the potential environmental impact by 14% with a thermal substitution rate of 20%. The findings of this study indicate that RDF is effective in reducing dependence on fossil fuels and lowering emissions and the potential environmental impact.

Abstract

Wastewater from metal plating businesses contains hazardous heavy metals, including chromium (Cr), which must be properly treated to avoid environmental contamination. Adsorption utilizing natural materials, such as sugarcane bagasse, is a promising option. This study compared the effectiveness of H2SO4-activated sugarcane bagasse with sugarcane bagasse-based activated carbon in removing total chromium (Cr-T) from metal plating wastewater and analyzed the effects of adsorbent mass and contact time. Atomic absorption spectrophotometry (AAS) was used to measure the final chromium concentrations after batch adsorption was conducted with different masses and contact periods. The findings revealed that the adsorption effectiveness increased as the adsorbent mass and contact duration increased, reaching an ideal point. While activated carbon achieved its peak at 12 g and 120 min (95% and 47.6% efficacy, respectively), activated bagasse performed best at 15 g and 150 min (51.9% and 43% effectiveness, respectively). Activated carbon performed better because of its increased surface area and pore structure resulting from carbonization. These results demonstrate that sugarcane bagasse is a potential, affordable, and sustainable natural adsorbent for lowering total chromium in industrial effluents, particularly when transformed into activated carbon.
