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

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.

Abstract

This study examines the barriers to green job development in Indonesia, focusing on economic, educational, and societal dimensions. Using a literature review methodology, the research synthesizes findings from academic studies, policy reports, and government publications to identify key challenges. Economic barriers include insufficient investment, inadequate fiscal incentives, and limited financial access for small and medium enterprises (SMEs). Educational barriers highlight a lack of targeted training programs, insufficient integration of sustainability in curricula, and disparities in access to education in rural areas. Societal barriers are reflected in low public awareness, negative perceptions of green jobs, and limited inclusion of marginalized communities. These challenges constrain the growth of green industries and limit workforce readiness for emerging sectors. The study concludes that addressing these barriers requires coordinated efforts, such as enhancing investments, reforming education systems, and fostering societal engagement.

Abstract

This study examines rural livelihood diversification patterns across six village communities in East Kalimantan Province, Indonesia. Using qualitative methodology including focus group discussions, in-depth interviews, and seasonal calendar development, the research analyzes how rural households adapt their economic strategies within contexts shaped by palm oil expansion and extractive industries. The study was conducted in Tepian Indah, Tepian Langsat, Tepian Makmur, Tebangan Lembak, Tepian Baru, and Tepian Budaya villages within Bengalon Subdistrict, Kutai Timur Regency. Findings reveal that livelihood strategies operate within complex intersections of demographic composition, land allocation systems, infrastructure access, and institutional capacity. Oil palm cultivation dominates five villages through both independent farming and plasma partnership arrangements, while mining employment characterizes Tebangan Lembak. Infrastructure disparities create differential opportunities for economic activities, with variations in electrical access, transportation connectivity, and water security affecting household adaptation strategies. Gender analysis shows women's critical roles in autonomous economic activities and environmental adaptation, though often underrecognized in development planning. Weak institutional capacity limits collective action for market integration despite formal farmer group existence. The study contributes to understanding rural economic adaptation in resource-rich regions by demonstrating how livelihood diversification reflects responses to both opportunities and constraints created by extractive industry presence.

Abstract

Bencana alam masih belum bisa diatasi sehingga terjadi banjir, kekeringan, dan perubahan iklim. Secara ekonomi, kekayaan masyarakat harus terhambat karena dampak bencana menghilangkan sebagian penghidupan. Secara sosial, itu mengarah pada peningkatan kemiskinan. Tujuan dari penelitian ini adalah untuk menemukan berbagai strategi berbasis kearifan lokal untuk mitigasi bencana alam dan kendala penerapan kearifan lokal pada generasi muda. Metode yang digunakan dalam penelitian ini adalah studi literatur dimana peneliti mengumpulkan beberapa sumber dari jurnal, buku, dan dokumen. Hasil penelitian menunjukkan bahwa masyarakat adat meningkatkan pengetahuan generasi muda sebagai langkah mendasar untuk mengatasi bencaba. Masyarakat yang memiliki pemahaman yang cukup tentang kebencanaan dan lingkungan hidup melanjutkan perilaku dalam bentuk perilaku nyata. Temuan lain yaitu adanya sanksi bagi masyarakat yang berani melanggar kebijakan tersebut. Aturan tersebut biasanya untuk mengatur masyarakat setempat agar tidak merusak ekosistem lingkungan. Pada akhirnya, banyak rintangan untuk menanamkannya pada generasi muda seperti gagal bertransformasi karena kearifan lokal tidak terdokumentasi. Transfer pengetahuan langsung secara lisan tanpa menuliskannya di kertas. Terlebih lagi, pengetahuan telah tergerus oleh teknologi ditengah arus globalisasi dimana generasi muda mencoba menggunakan teknologi daripada kearifan lokal.

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.
