Abstract

The utilization of biomass waste as a raw material for functional materials represents a sustainable approach in the development of carbon-based materials. This study aims to evaluate the potential of activated carbon derived from durian peel as a support for the immobilization of fatty hydroxamic acids. Activated carbon was synthesized through sequential stages of raw material preparation, carbonization, and chemical activation to produce a porous material with surface properties favorable for immobilization processes. The characterization results indicate the formation of a well-developed porous structure along with the presence of oxygen-containing functional groups, which play a crucial role in interactions with fatty hydroxamic acids. Fatty hydroxamic acids were synthesized from vegetable oil and employed as the target compounds in the immobilization process. Immobilization was carried out using a direct contact method between the activated carbon and the fatty hydroxamic acid solution under controlled conditions. The results demonstrate that durian peel–based activated carbon effectively immobilizes fatty hydroxamic acids through a combination of physical adsorption mechanisms and chemical interactions on the carbon surface. The immobilization efficiency obtained indicates that pore characteristics and surface functional groups of the activated carbon strongly influence its performance as an immobilization medium. Stability tests further reveal that the immobilized system exhibits satisfactory resistance to washing and repeated use. Overall, this study confirms that activated carbon derived from durian peel has significant potential as an immobilization medium for chemical compounds, while simultaneously adding value to biomass waste and supporting the development of environmentally friendly materials for chemical and environmental applications.

Abstract

Mangrove ecosystems play an essential role in carbon sequestration and coastal protection. This study analyzes changes in mangrove cover and associated carbon storage at Cemara Beach, West Lombok Regency, using Sentinel-2 satellite imagery from 2019 and 2024. Supervised classification with the CART algorithm was applied through Google Earth Engine, supported by field verification and stakeholder interviews for management assessment. Results indicate an expansion of mangrove cover from 66,6 ha in 2019 to 71,63 ha in 2024, an increase of 4,97 ha (7,46%). Correspondingly, carbon stocks rose from 14.728,26 tons C to 16.252,45 tons C, with mangroves contributing the largest portion (over 62%). SWOT analysis showed strong ecological potential and supportive policies but highlighted challenges such as limited funding, land-use pressure, and low community awareness. Strengthening multi-stakeholder collaboration, environmental education, and sustainable rehabilitation programs is recommended to enhance ecological resilience and maximize blue carbon benefits.

Abstract

Pencemaran amonium pada air limbah peternakan merupakan salah satu permasalahan lingkungan yang memerlukan teknologi pengolahan yang efektif dan berkelanjutan. Penelitian ini bertujuan untuk mensintesis zeolit dari abu terbang batubara menggunakan metode alkali fusion-hidrotermal dan mengevaluasi kinerjanya dalam menjerap amonium pada air limbah peternakan. Abu terbang direaksikan dengan NaOH pada suhu 550°C selama 1 jam dan dikristalisasi secara hidrotermal pada suhu 100°C selama 24 jam untuk menghasilkan zeolit tipe NaA. Hasil karakterisasi menunjukkan peningkatan kapasitas tukar kation dari 38,6 menjadi 176,4 meq/100 g setelah proses sintesis. Pengujian adsorpsi dilakukan menggunakan variasi dosis adsorben 1–8 g/L, waktu kontak 15–120 menit, dan konsentrasi awal amonium 25–200 mg/L. Hasil penelitian menunjukkan bahwa efisiensi penyisihan amonium meningkat dari 52,8% pada dosis 1 g/L menjadi 91,7% pada dosis 8 g/L. Kondisi optimum diperoleh pada dosis adsorben 8 g/L dan waktu kontak 120 menit dengan kapasitas adsorpsi maksimum sebesar 31,84 mg/g. Analisis isoterm menunjukkan bahwa adsorpsi mengikuti model Langmuir dengan koefisien determinasi (R²) sebesar 0,987, sedangkan model kinetika pseudo-second-order memberikan kecocokan terbaik dengan nilai R² sebesar 0,992. Pengujian kolom kontinu menghasilkan efisiensi penyisihan rata-rata 93,4% sebelum mencapai titik breakthrough. Uji regenerasi menunjukkan bahwa zeolit masih mempertahankan 84,6% kapasitas adsorpsinya setelah lima siklus penggunaan. Hasil penelitian membuktikan bahwa zeolit berbasis abu terbang batubara memiliki kemampuan tinggi dalam menjerap amonium dan berpotensi diterapkan sebagai adsorben berbiaya rendah untuk pengolahan air limbah peternakan secara berkelanjutan.

Abstract

The integration of technology and bioeconomy presents a promising theoretical framework for enhancing agricultural productivity in response to global challenges such as climate change, food insecurity, and resource depletion. This study offers a conceptual analysis of how technological innovations—including precision agriculture, digital monitoring systems, and biotechnology—can be synergized with bioeconomic principles to optimize input efficiency, reduce environmental impact, and promote sustainable agricultural practices. Drawing from interdisciplinary literature, the paper explores key theoretical models such as sustainable intensification, circular bioeconomy, and smart farming systems, emphasizing their potential to transform traditional agricultural paradigms. Furthermore, the study examines the economic implications of this integration, highlighting its role in improving farm-level profitability, strengthening rural economies, and supporting policy development for sustainable agriculture. By synthesizing scientific and economic perspectives, this theoretical inquiry contributes to a deeper understanding of how innovation-driven, bio-based strategies can reshape agricultural systems toward greater resilience and sustainability. The findings underscore the importance of continued research and policy alignment to operationalize these concepts in diverse agroecological and socioeconomic contexts.

Abstract

This study evaluated the performance of an integrated electrochemical and activated carbon adsorption process for the treatment of landfill leachate. The initial leachate characteristics showed a COD of 4,850 mg/L, color intensity of 6,200 Pt Co, and ammonia concentration of 780 mg/L, with a low BOD/COD ratio indicating poor biodegradability. The electrochemical process operated at an optimum current density of 20 mA/cm² achieved 46.3 percent COD removal and 62.5 percent color reduction within 120 minutes, with an energy consumption of 18.4 kWh/kg COD removed. Standalone adsorption using 20 g/L of activated carbon reduced COD by 38.7 percent and color by 71.2 percent within 150 minutes; however, adsorption capacity declined by 35 percent after two cycles without regeneration. The integrated system operated at pH 6, current density of 20 mA/cm², and 120 minutes hydraulic retention time achieved 78.9 percent COD removal, 91.4 percent color removal, and 64.8 percent ammonia reduction. The specific energy consumption decreased to 12.6 kWh/kg COD removed, demonstrating improved energy efficiency compared to the electrochemical process alone. In situ electrochemical regeneration conducted for 30 minutes at 30 mA/cm² restored up to 87 percent of the initial adsorption capacity after three operational cycles. These results confirm a significant synergistic effect between electrochemical oxidation and activated carbon adsorption, leading to enhanced treatment efficiency and operational stability for complex landfill leachate.
