Abstract

Indonesia possesses abundant biomass resources with significant potential to support the transition toward a sustainable energy system. This study evaluates the energy potential of major biomass resources in Indonesia, including oil palm residues, rice residues, corn residues, livestock manure, sugarcane bagasse, municipal solid waste, and cassava residues. A combination of quantitative and qualitative approaches was employed using national statistical data, government reports, and scientific literature. Energy potential was estimated based on biomass availability, calorific value, conversion efficiency, and energy losses during utilization. The results show that biomass has the potential to generate 30.76 GW of energy, equivalent to 12.8% of Indonesia’s final energy consumption in 2023. Oil palm residues provide the largest contribution (13.34 GW), followed by rice residues (7.12 GW) and livestock manure (5.49 GW). Despite ongoing challenges related to fossil fuel dependence, greenhouse gas emissions, and deforestation, biomass offers a promising alternative energy source. Furthermore, the Gross External Damages (GED) analysis indicates that biomass is more economically competitive than fossil fuels when environmental costs are considered. These findings highlight the strategic role of biomass in supporting Indonesia’s sustainable energy transition, climate change mitigation, and societal welfare improvement.

Abstract

Young leachate from the inlet zone of Muara Fajar Landfill is characterized by high acidity (pH 5.5) and pollutant load, posing risks of heavy metal mobilization into groundwater. This study evaluates the performance of alkali-activated duck eggshell biosorbent as a neutralizing and clarifying agent for acidogenic leachate. A batch system was employed with varying contact times (0–120 mins), 2% (w/v) adsorbent dosage, and 175 rpm agitation. Results showed the biosorbent effectively increased leachate pH from 5.5 to 6.6, complying with MoEF Regulation No. 59/2016 standards. Turbidity decreased by 37% (72.4 to 45.6 NTU) at the optimum time of 60 minutes. Kinetic analysis fitted the Pseudo-Second Order model (R2= 0.9557) with a maximum adsorption capacity (qe) of 1.49 NTU.L/g and rate constant (k2) of 0.041 g/NTU.min, indicating dominant chemisorption mechanisms. Duck eggshell waste shows potential as an economical, eco-friendly pre-treatment for acidic leachate.

Abstract

This study evaluates the potential of activated carbon derived from oil palm mesocarp fibers (OPMF) using 0.5 M NaOH activation as a sustainable solution for the advanced treatment (polishing) of POME. Through a pyrolysis process at 250°C, the carbon produced a 16.5% yield and 4.44% moisture content, meeting the SNI 06-3730-1995 standards. The results indicate that an adsorbent dosage of 3 grams per 200 mL of sample significantly reduced COD levels by 50.03% (to 14,261 mg/L), although the final value has not yet met the quality standards of Permen LHK No. 5 of 2014. However, this activated carbon proved highly effective in improving acidity levels, increasing the effluent's pH from 5.37 to 7.31, thereby successfully.

Abstract

Toxic heavy metals in aquatic ecosystems pose serious environmental and ecological risks. This study evaluates the adsorption performance of H3PO4-activated oil palm frond biochar for removing Pb(II) and Cu(II) from a multi element system. Competitive adsorption was simulated using Certified Reference Material (CRM) containing 23 elements. The optimized adsorbent dosages were 0.05 g for kinetic experiments and 0.01 g for isotherm experiments, with metal concentrations of up to 10 mg/L in 25 mL of solution. Metal concentrations were analyzed using Inductively Coupled Plasma-Optical Emission Spectrometry (ICP-OES 5800 VDV). Kinetic analysis over 180 min showed that the adsorption process followed the pseudo-second order model, while equilibrium data were best described by the Langmuir isotherm, indicating selective adsorption toward competing metal ions. The adsorbent demonstrated high removal efficiencies for Fe, Al, Cu, Pb, and Cr, exceeding 80%. These results indicate that H?PO?-activated oil palm frond biochar has strong potential as an effective adsorbent for treating wastewater containing multiple hazardous heavy metals.
