Abstract

Agroforestry in North Kalimantan offers a promising avenue for balancing community livelihoods with carbon sequestration, crucial for the REDD+ initiatives. This paper examines the potential of agroforestry in North Kalimantan to support the REDD+ program, addressing both environmental sustainability and socio-economic development. Through field observations and interviews across four regencies and one city in North Kalimantan province, various agroforestry practices were identified, including improved fallows, alley cropping, scattered trees on cropland, living fences, and silvofishery. Challenges such as cultivation practices, post-harvest processing, market access, and financing were also explored. Three potential agroforestry models were proposed to enhance carbon capture while promoting local economic resilience. The paper underscores the importance of further research and community involvement to refine and expand these agroforestry approaches, offering hope for both local prosperity and global carbon reduction efforts.

Abstract

Research on the carrying capacity of the environment for mining activities, as indicated by the dynamics of stored carbon stocks will be carried out in Bulungan Regency, North Kalimantan in early 2022. Data was collected both through literature studies and surveys calculating tree diameter at breast height in the field as a basis calculation of stored carbon stock. Land cover spatial data analysis is used as a reference for calculating stored carbon stocks at the study site. The results of a comparison of stored carbon stocks between forest and land clearing and reclamation based on planned mining activities show that the area that can be utilized is 1,578.3 Ha. There are efforts to restore carrying capacity and carrying capacity based on mining activities with broad impacts that can be used is 1,947.84 Ha. The usable area can be increased 1.2 times from the recommended area (2,337,415 Ha) to accommodate the required land as an overburden area. This addition is made possible through the application of various appropriate technologies. The carrying capacity of the environment in this study, although only limited to the dynamics of stored carbon stocks, shows that the results can be used as a solution for overlapping permits in forest areas in accordance with the laws and regulations in effect since the Ministry of Environment and Forestry has so far provided a maximum area of 10 percent of the area areas affected by overlapping cases.

Abstract

An inclusive coffee supply chain refers to a production and distribution system that involves various stakeholders, including small-scale farmers, in the process. Inclusivity, in this context, means ensuring the involvement of all actors in the chain, from farmers to consumers, with a focus on equality and empowerment. This research aims to advocate for responsible coffee production and consumption in a region crucial for biodiversity, namely Aceh Tengah District, while also promoting gender equality in all responsible business practices. Data were collected through literature reviews and direct interviews with stakeholders, ranging from corporate to local levels, and analyzed using Focus Group Discussion (FGD) analysis. The study revealed insights into the supply chain profile in Aceh Tengah, existing policy, institutional conditions, and processes, the vulnerability context of coffee farmers' livelihoods, the conditions of their livelihood assets, and sustainable livelihood strategies suitable for their needs and conditions. This research is expected to contribute to the creation of responsible coffee production and consumption and advocate for gender equality in responsible business practices within the coffee sector.

Abstract

This study evaluates the economic feasibility of developing Intermediate Waste Treatment Facilities (ITFs) utilizing Waste-to-Energy technology in Jakarta's South Service Area. A comparative analysis was conducted using two scenarios: conventional landfill management versus ITFs implementation at two potential locations—Pesanggrahan (South Jakarta) and Sukapura (North Jakarta). The research employed secondary data analysis over one month in August 2021, utilizing financial indicators including Net Present Value (NPV), Internal Rate of Return (IRR), and Benefit Cost Ratio (BCR). Environmental and social externalities were integrated into the economic assessment. Results demonstrate that conventional landfill approaches yield negative present value of IDR 5.24 billion, indicating financial unsustainability. Conversely, WtE technology scenarios show positive economic viability: Pesanggrahan achieves NPV of IDR 441 million (IRR 12.12%, BCR 1.08), while Sukapura demonstrates superior performance with NPV of IDR 1.25 billion (IRR 16.15%, BCR 1.23). The findings establish clear economic justification for transitioning from disposal-based to resource recovery systems, with industrial zone locations offering strategic advantages for ITF development in Jakarta's waste management modernization strategy.

Abstract

Environmental pollution caused by unmanaged scrap battery smelting activities in Cinangka and Cinangneng villages, Bogor Regency, has led to heavy metal contamination, particularly lead (Pb), which threatens public health and the ecosystem. This study employs the Analytical Hierarchy Process (AHP) to evaluate four contaminated land remediation methods encapsulation, on-site stabilization and solidification, phytoremediation, and dig and fill based on legal, technical, financial, and environmental aspects. The analysis results indicate that the dig-and-fill method is the best solution for addressing contamination at priority sites with high pollution levels and proximity to residential areas. This method effectively removes contaminated soil and replaces it with pollutant-free soil, thereby minimizing health risks. This study provides strategic recommendations to support land remediation policies in Bogor Regency.

Abstract

Andesite mining activities cause land degradation that requires revegetation efforts for ecosystem restoration. This study aims to evaluate the ecological feasibility of bamboo as an alternative revegetation species for post-mining sites compared to conventional pioneer plants through a systematic literature review. Analysis was conducted on 45 relevant scientific publications from indexed academic databases, focusing on adaptability, soil improvement, erosion control, and contribution to biodiversity. Results show that bamboo has significant advantages in root systems (fine root biomass 1.1-4.5 kg m⁻³), erosion control effectiveness, and carbon sequestration potential (6-13 Mg ha⁻¹ year⁻¹). Bamboo also demonstrates high adaptability to marginal land conditions and provides sustainable economic value through selective harvesting without damaging the root system. Compared to conventional pioneer plants, bamboo provides more stable long-term contributions to post-mining ecosystem restoration. This study recommends the use of bamboo as a primary component in andesite post-mining land revegetation programs in Indonesia.
