PENYERAPAN KARBON PADA LAHAN AGROFORESTRI DI KABUPATEN LOMBOK TENGAH
Agroforestry is essential in climate change mitigation in West Nusa Tenggara Province. This study aims to estimate the potential for carbon sequestration in different agroforestry levels. The data collection method was field observation. The Biomass estimation method was a non-destructive method using allometric models. ANOVA and Tukey HSD tests determine the carbon sequestration differences between agroforestry levels. The results showed that biomass, stock, and carbon sequestration increased frequently with increasing agroforestry levels. This condition is due to differences in the allocation of woody tree utilization space, which increased in advanced agroforestry. More established farmers implement the advanced agroforestry level with adequate resources. They can develop agroforestry silviculture more intensively, which supports optimal tree growth. Due to agroecological factors, the potential for carbon stock is still lower than the agroforestry system around the research location and the average in Southeast Asia. Likewise, the potential for carbon sequestration in the agroforestry system is still smaller than the regional CO2 emissions. The carbon emissions offsetting in the FOLU sector (forestry and other land use) are by increasing vegetation cover on land in forest areas with advanced agroforestry systems that the community has developed on their land. The government's role in agroforestry improvement is to increase community awareness and provide technical training, economic incentives, monitoring, and evaluation regularly. The study result is suitable as one of the inputs for establishing a sustainable agroforestry management plan. Expansion of the sample and research time can improve this study in the future.

PERTARUNGAN EPISTEMIK : BISNIS PANGLONG ARANG SUKU AKIT DAN KEBIJAKAN HUTAN MANGROVE DI INDONESIA
Amid increasing global attention to coastal ecosystem conservation, the traditional charcoal production practices of the Akit community in Bantan Village, Bengkalis Regency, reflect the tension between local economic needs and environmental conservation efforts. The charcoal panglong activity, which has been going on for generations, is the main source of livelihood for the indigenous community, while at the same time contributing to the degradation of mangrove forest areas. In this context, this research critically examines the social, economic and ecological dynamics that shape charcoal business practices, and explores the complex interactions between local communities and Indonesia's mangrove forest management policy regime. An ethnographic approach was chosen to enable an in-depth understanding of the daily practices, social structures and power relations that shape the relationship between local communities and their surrounding environment. Data were collected through participatory observation, in-depth interviews with two heads of farmer groups holding forest management rights (HKm), 25 charcoal panglong workers, and 13 home-based charcoal panglong owners, as well as document analysis of relevant policies and regulations. The findings of this study show that the charcoal panglong business is not just an economic activity, but an integral part of the Akit community's livelihood system and cultural identity. However, production practices based on intensive exploitation of mangrove forest resources have resulted in ecological degradation of coastal areas. Meanwhile, mangrove conservation policies that are generally centralised and technocratic tend to ignore local knowledge and community subsistence needs, resulting in structural tensions between the state and indigenous communities. This research recommends a more participatory and community-based policy approach, including the adoption of sustainable charcoal production technologies and the integration of local businesses into mangrove ecosystem rehabilitation schemes. Thus, the transformation of mangrove forest governance can be directed towards a more equitable, ecological and contextualised model.

Penerapan Ekonomi Hijau Swedia dan Indonesia: Energi dan Mitigasi Perubahan Iklim
In Sweden, from 1990 to 2018, it was shown that economic and population growth can align with the reduction of carbon dioxide (CO2) emissions. The population increased by more than 1.6 million and the GDP nearly doubled, while CO2 emissions dropped by 27%. The GDP per unit of CO2 fell by 60%, indicating an improvement in economic efficiency without shifting emissions to other countries. The reduction in emissions in Sweden largely occurred between 2003 and 2014, thanks to technological advancements, renewable energy, energy efficiency, and industrial changes. Sweden is committed to achieving net-zero greenhouse gas emissions in 2045, requiring a reduction of 5-8% per year from 2015 to 2045. In Indonesia, the Green Economy has been implemented since 2013 through cooperation between Bappenas and the Global Green Growth Institute (GGGI). In 2020, Indonesia set a target to reduce CO2 emissions by 29% by 2030 with its own efforts, or 41% with international support. The government also established Presidential Regulation No. 98 of 2021 to support emission reductions through Carbon Economic Value (NEK). However, CO2 emissions from the energy sector in Indonesia tended to increase by an average of 3.57% per year between 2010 and 2019, making Indonesia the 10th largest CO2 emitter in the world. The high use of fossil energy indicates the need to optimize renewable energy resources such as geothermal, hydropower, nuclear energy, and solar power. Sweden and Indonesia are committed to reducing carbon emissions and promoting the Green Economy by emphasizing the importance of transitioning to renewable energy resources and implementing policies that support sustainable development to mitigate the impact of climate change.
