http://journalssr.com/index.php/ssr <p><strong><em>Sustainability Science and Resources</em></strong> (ISSN 2809-6029) is an open access, peer-reviewed, journal published by the Indonesian Forestry Certification Cooperation (IFCC) in collaboration with Millennium Resource Alternatives (MRA) LLC and Sustainable Development Indonesia (SDI). Published biannually as April-September and October-March editions, the journal aims to provide a scholarly forum for the dissemination and exchange of research and developments in biological, physical, and social sciences pertinent to sustainability and Sustainable Development Goals (SDGs). It encourages an interdisciplinary approach to sciences that advances our understanding of the complex interaction between human and natural resources affecting the earth’s life support systems. It also promotes academic, policy, and practical work addressing the dynamic equilibrium of the economic, environmental, and social pillars of sustainability. The journal publishes original research, reviews, and commentaries.</p> <p>We are pleased to announce that SSR Journal has been officially integrated into the <em><strong>International System for Agricultural Science and Technology (AGRIS)</strong></em> — a flagship initiative of the <em><strong>Food and Agriculture Organization (FAO) of the United Nations</strong></em>.</p> The Indonesian Forestry Certification Cooperation en-US Sustainability Science and Resources 2809-6029 http://journalssr.com/index.php/ssr/article/view/75 <p><strong><em>Garcinia afzelii</em></strong><em>, </em>a valuable non-timber forest product (NTFP), is utilised for its edible seeds, chewing sticks, and medicinal properties. However, its survival is threatened by overharvesting, slow growth, and limited natural regeneration, warranting its classification as vulnerable. To mitigate these risks, conservation efforts, including propagation, are essential. This study aimed to develop a vegetative propagation protocol for&nbsp;<em>G. afzelii</em>&nbsp;using stem cuttings treated with varying concentrations of Indole-3-Butyric Acid (IBA), hypothesising that IBA would improve rooting success. Seedlings were cultivated for 12 months in a nursery, after which semi-hardwood stem cuttings were treated with IBA concentrations of 0.0% (control), 0.1%, 0.3%, and 0.8%. These cuttings were propagated in non-mist propagators using river sand as the growth medium, arranged in a Completely Randomised Design (CRD) with five replications per treatment (10 cuttings each). Results indicated that IBA significantly (P&nbsp;≤ 0.05) enhanced root development, with the 0.8% IBA treatment yielding the longest roots (9.19 cm vs. 6.00 cm in control) and the highest number of lateral roots (59.31 cm vs. 39.46 cm in control). Although the untreated cuttings produced a higher number of roots, they accounted for only 27.90% of root formation, while the three IBA-treated cuttings contributed 72.10%. Conversely, the control cuttings recorded a higher survival rate (80.00%) than the IBA (70.00%). IBA-treated <em>G. afzelii</em> stem cuttings achieved a 62.10% shoot development rate, compared to 37.90% in the untreated cuttings. These findings suggest that IBA promotes shoot and root formation, making it an effective protocol for mass propagation. Thus, IBA application in stem-cutting propagation could optimise root establishment and resource mobilisation, supporting the conservation and cultivation of<em>&nbsp;G. afzelii.</em></p> Anthony Antwi-Wiredu John Kobina Mensah Ebenezer Ofori Padmore Boateng-Ansah Naomi Adoma Fosu Joseph Mireku Asomaning Copyright (c) 2025 Sustainability Science and Resources https://creativecommons.org/licenses/by/4.0 2025-11-10 2025-11-10 9 1 17 10.55168/ssr2809-6029.2025.9001
