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

Malinau Robusta coffee demonstrates untapped potential within the specialty coffee market. This study aims to evaluate the quality of Malinau coffee comprehensively and benchmark it against prominent specialty coffees such as Gayo, Toraja, and Kintamani. A descriptive quantitative method was employed to analyze critical parameters including caffeine content, moisture level, defect value, impurity level, grain size, and flavor profile. Coffee samples were gained from nine coffee-producing villages in Malinau Regency, involving 28 farmers covering 190 ha of coffee plantations. The results identified distinct strengths of Malinau coffee, notably its low moisture level (10.2%) and high caffeine content (1.94%) among the samples, offering a strong and intense flavor profile including chocolatey, a bitter aftertaste, and fruity undertones. Challenges for Malinau coffee includes high defect value (65.7/300 g) and impurity level (0.6%), which undermine its marketability in premium segments. To bring Malinau coffee up to par with other established specialty coffees, improvements in post harvest handling are needed, particularly sorting, quality control and consistent processes methods. By adopting innovative cultivation and processing, Malinau coffee holds strong potential as a competitor of specialty coffee, both for domestic and global markets while highlighting its unique regional identity. Keywords: Malinau coffee, North Kalimantan, Quality improvement, Robusta, Specialty coffee.

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

The socioeconomic feasibility of Waste-to-Energy (WtE) facilities is analyzed through a case study in South Jakarta, emphasizing its potential as a sustainable urban waste management solution. This study evaluates the comparative costs and benefits of implementing an Intermediate Waste Treatment Facility (ITF) in three prospective locations: Sukapura (North Jakarta), Pesanggrahan, and Petukangan Selatan (South Jakarta). Results highlight Sukapura’s strategic advantage due to its industrial zoning, resulting in lower residential density, reduced social resistance, and minimized environmental costs. By contrast, higher costs are associated with South Jakarta sites due to greater population densities, leading to amplified pollution impacts. Key findings reveal that WtE facilities generate significant environmental and economic benefits, including reduced greenhouse gas emissions, improved air and water quality, job creation, and regional budget efficiencies. The integration of circular economy principles, such as waste reduction and resource efficiency, further underscores the importance of sustainable waste management strategies. However, successful WtE implementation requires careful alignment with land-use planning and community engagement to address socio-environmental challenges effectively. This study offers valuable insights for policymakers and urban planners, proposing that strategic site selection and adaptive approaches are critical for achieving long-term sustainability in waste management.
