Abstract

Climate change mitigation activities in the forestry sector are currently widely carried out through the REDD+ scheme, especially in tropical regions. In the REDD+ scheme, information on forest carbon stocks in areas used as REDD+ activity locations will be essential. This study aims to estimate aboveground carbon stocks in the damar repong landscape in Pesisir Barat Regency, Lampung Province, which consists of three main land cover types, namely repong damar, natural forest, and mixed gardens. The approach used is a non-destructive method with a purposive sampling technique on 42 sample plots. Vegetation data were collected by measuring the diameter, height, and density of wood, then biomass was calculated using allometric equations and converted into carbon stocks. The results showed that the highest average carbon stock was found in repong damar at 269.74 tC/ha, followed by natural forest at 167.01 tC/ha, and mixed gardens at 96.61 tC/ha. Variations in carbon stocks in the three land covers were influenced by stand structure, tree size, and vegetation density. Statistical analysis showed the highest level of uncertainty in natural forest and the lowest in mixed gardens. This study confirms that traditional agroforestry systems such as damar repong have significant potential in mitigating climate change through high carbon storage.

Abstract

This study evaluates the effectiveness of Indonesia’s Social Forestry (SF) policy implementation from 2016 to 2024 through a document-based meta-analysis and systematic literature review. The policy, initiated under Ministerial Regulation No. P.83/2016, aims to address forest tenure inequality and improve community welfare through legal access to forest management. A total of 23 documents, including official government reports, NGO evaluations, and peer-reviewed publications, were analyzed using descriptive quantitative and thematic qualitative methods. The findings reveal that Social Forestry has significantly expanded legal access to forest areas, reaching over 8 million hectares through approximately 11,000 decrees, and has generated positive economic, social, and environmental outcomes. The program enhanced household income, strengthened institutional participation, and promoted conservation practices such as agroforestry and forest zoning. However, implementation effectiveness remains constrained by weak institutional capacity, limited financing, inconsistent data integration, and inadequate cross-sectoral coordination. Strengthening local institutions, establishing interoperable reporting systems, and developing community enterprises through digital and market-based incentives are essential for long-term sustainability. The study concludes that the success of Social Forestry depends on collaborative governance and adaptive policies that balance administrative expansion with substantive socio-ecological outcomes.

Abstract

Aren (Arenga pinnata) has emerged as a multifunctional tropical species. It has the potential to contribute to sustainable value chain development, the circular bioeconomy, and rural livelihoods. Nevertheless, existing literature remains fragmented and addresses ecological, technological, and governance dimensions in isolation. This study systematically reviews the literature on the sustainable value chain transformation of A. pinnata within tropical bioresource systems. It identifies factors influencing its transition from a traditional multipurpose palm to a strategic bioresource platform. A systematic literature review was conducted through a structured process. The steps included search, screening, eligibility assessment, data extraction, and thematic synthesis. The review combined empirical studies with broader literature on circular bioeconomy, value chain restructuring, social sustainability, and governance. The analysis covered four thematic domains: upstream resource systems, midstream processing and upgrading, downstream diversification, and market or institutional alignment. The review shows that A. pinnata can drive transformative change. This is due to its multifunctionality, ecological adaptability, and diverse product pathways. Upstream research highlights its role in agroforestry, biodiversity-linked landscapes, and livelihood systems. Midstream studies identify opportunities for product stabilization, fermentation, and process improvement. Downstream investigations show promising use in thermoplastic starch, composites, functional biomaterials, and circular by-products. However, integration among these advances is weak. Technical innovation often outpaces commercialization and governance. Value distribution, coordination, and inclusion also remain underdeveloped. The study concludes that the sustainable transformation of A. pinnata requires integrating resource sustainability, technological upgrading, and market or institutional alignment. This review offers an integrated framework for understanding aren-based transformation and identifies priorities for future research on commercialization, circularity, and inclusive tropical bioresource development.

Abstract

The government has issued a policy on the standard size of blue swimming crabs caught to support fisheries management, but it is difficult for business actors to comply with. This study aims to analyze the implementation of the Regulation of the Minister of Marine Affairs and Fisheries No. 7 of 2024 concerning Blue swimming crab Management on the East Coast of Lampung. The research uses a qualitative approach with a case study method, with in-depth interviews, participatory observations, focus group discussions, and documentation studies. The analysis of policy implementation examines fishermen's compliance with the blue swimming crab size standards set by the government. The results of the study show that the cause of the difficulty in implementing the blue swimming crab size provisions is the limited supervision and the lack of sanctions for violations. The orientation of fishermen's behavior still focuses on profits and the limitations of fishing technology that are not selective and destructive. The government must involve all business actors in the trading chain of blue swimming crab commodities to unify perceptions and increase fishermen's understanding of sustainable fisheries management policies on the East Coast of Lampung.

Abstract

Mangroves play a crucial role in climate change mitigation and coastal protection, yet they face pressures from environmental degradation and limited policy implementation. This study employs a systematic literature review to examine the role of artificial intelligence (AI) in mangrove management and its policy implications in Indonesia. Findings indicate that AI, through machine learning, deep learning, and integration with remote sensing data, is effective in monitoring, mapping, restoration assessment, and predicting ecosystem changes. These technologies have the potential to support evidence-based policymaking, including prioritizing restoration areas, optimizing resource allocation, and enhancing decision-making systems. However, AI adoption faces challenges related to data quality and availability, institutional capacity, and ethical and governance concerns. The study highlights opportunities for developing inclusive and interdisciplinary AI governance frameworks, which could strengthen policy effectiveness and promote sustainable mangrove management in Indonesia.

Abstract

Indonesia faces increasing pressure on its natural forest resources due to deforestation and rising demand for wood, encouraging the utilization of fast-growing species such as sengon (Falcataria moluccana) and underutilized invasive species such as African tulip (Spathodea campanulata). However, both species are characterized by naturally light surface colors, which are often perceived as less attractive for decorative and interior applications. Oil heat treatment (OHT) has been used to modify wood color and enhance visual appearance. This study evaluated the effects of OHT at 160°C, 180°C, 200°C, and 220°C for 2 hours on color changes and public color preferences of sengon and African tulip woods. Color changes were visually observed and quantitatively analyzed using the CIE-LAB color system, while preference data were collected through an online survey involving male and female respondents. The results showed that OHT caused significant darkening of wood surfaces, with African tulipwood exhibiting greater color changes than sengon. Preference analysis indicated that female respondents tended to favor wood colors heat-treated at moderate temperatures (180°C), whereas male respondents preferred darker colors produced at higher temperatures (200–220°C). For African tulip wood, treatment at 200°C was the most preferred overall by both genders. These findings demonstrate that oil heat treatment effectively modifies wood color and that consumer color preferences vary by gender, which may be considered in visually oriented wood applications.

Abstract

The development of dragon fruit through agroforestry plays an important role because it increases land cover, suppresses pests and diseases, and reduces capital costs compared to monoculture systems. This study aims to analyze the dragon fruit agroforestry systems developed in Bumi Mulyo Village, Sekampung Udik District, East Lampung Regency. A qualitative approach using a case study method was employed in this research. Data were collected through in-depth interviews, field observations, and document analysis. The collected data were analyzed to identify plant species and planting patterns in dragon fruit agroforestry systems. The results showed that the agroforestry system consisted of dragon fruit (Hylocereus polyrhizus) as the main crop; kapuk (Ceiba pentandra) as a living support tree and live fence tree; and several complementary plant species, namely avocado (Persea americana), cocoa (Theobroma cacao), mamey sapote (Pouteria sapota), black sapote (Diospyros nigra), durian (Durio zibethinus), papaya (Carica papaya), chili (Capsicum annuum), banana (Musa spp.), melinjo (Gnetum gnemon), and coconut (Cocos nucifera). The kapuk tree functions both as a living support tree for dragon fruit and as a live fence tree. Its leaves are also used by farmers as animal feed. The planting patterns applied by farmers include: (1) dragon fruit–kapuk; (2) dragon fruit–kapuk–avocado; and (3) dragon fruit–kapuk–fruit trees. These variations demonstrate farmers' adaptation in optimizing growing space to maximize the economic and ecological functions of the agroforestry system. Farmers are encouraged to develop more complex agroforestry systems from simple ones in order to increase income and support soil and water conservation.
