Abstract

Deforestation remains a critical environmental issue, contributing to biodiversity loss and increased carbon emissions, particularly in tropical forests. This study aims to explore how the optimization of Non-Timber Forest Products (NTFPs) can reduce deforestation and support carbon emission mitigation targets. Using a library-based research method, data were collected from primary and secondary sources, including books, scientific journals, reports, and case studies related to NTFPs, deforestation reduction, and carbon management. Content analysis was employed to identify patterns, relationships, and insights across the literature. Findings indicate that sustainable NTFP utilization provides alternative livelihoods, encourages community participation in forest management, preserves forest cover, and maintains carbon stocks. NTFPs demonstrate the potential to harmonize ecological conservation with socio-economic development, provided that supportive policies, governance frameworks, and monitoring mechanisms are implemented. The study concludes that integrating NTFPs into forest management strategies offers a practical, scalable solution for achieving both deforestation reduction and carbon emission mitigation objectives.

Abstract

This study aims to analyze the acoustic characteristics of coconut-fiber-based Cement-Bonded Particleboard (CBPB) through measurements of the Sound Absorption Coefficient (SAC, α) and Transmission Loss (TL). CBPB samples were fabricated with thickness variations of 12, 16, and 20 mm and tested using an impedance tube in accordance with ISO 10534-2:1998 for SAC and ASTM E90-09 (2016) for TL measurements. The study examined the effect of panel thickness on sound absorption and transmission loss across a frequency range of 125–4000 Hz. The results showed that the α value increased with both frequency and panel thickness, reaching a maximum of 0.78 at frequencies of 2500–3150 Hz for the 20 mm panel. The TL measurements indicated that the highest transmission loss reached 42 dB at a frequency of 4000 Hz. These findings suggest that thicker CBPB panels provide better acoustic performance, both in absorbing sound and reducing transmission. Overall, coconut-fiber-based CBPB demonstrates strong potential as an eco-friendly structural acoustic material suitable for applications in sustainable building design, interior partitions, and noise control solutions.
