INTRODUCTION
The Community Forestry (HK.
Program is a strategic policy aimed at improving community welfare while maintaining the ecological function of the forest (Rumaday et al.
The Andalambe HKm, located in Andalambe Village.
Tongauna District.
South Konawe Regency, covers an area of 630 ha and represents a concrete manifestation of the government's efforts to directly involve the community in forest The Village Forest Farmers Group is a key pillar in managing this areaan is committed to the responsible use of forest resources.
As a manifestation of this commitment, farmers have planted fast-growing wood species, particularly Sengon (Falcataria moluccan.
and Jabon (Neolamarckia cadamb.
, which have now reached a productive age of 5 to 7 years.
The 5-7 year period is a critical and highly anticipated phase in the Sengon and Jabon cultivation cycle, during which wood can be harvested to meet industrial needs, particularly for processed wood and pulp.
Logging activities soon to be carried out by this Farmers Group will undoubtedly have a significant economic impact on the However, behind the potential income from primary wood, there are hidden problems and opportunities that are often overlooked, such as logging waste.
Logging activities are inextricably linked to waste production This waste can include defective wood, branches, twigs, trunk bases, and pieces of wood that do not meet the marketable size or quality standards.
Conventionally, this wood waste is often considered worthless, left to rot at the logging site, or burned directly.
This open burning practice is not only economically wasteful but also has negative environmental impacts, such as air pollution, greenhouse gas emissions, and the potential for uncontrolled fires (Nadun and Rakhmah 2022.
Soenarno.
Yuniawati.
Dulsalam.
Suhartana et al.
Thus a new paradigm needs to be introduced.
Waste from Sengon and Jabon logging is not actually waste but rather a potential renewable energy resource.
Wood residue from felling can be further processed into solid fuels, such as wood chips or wood pellets, which have a high market value and are in increasing demand.
Converting waste into fuel not only solves the environmental problem of logging waste but also creates an additional source of added value for farmer groups that have previously wasted (Rimantho et al.
The potential of Sengon and Jabon as raw materials for wood pellets has been Wood pellets from Sengon wood have an adequate calorific value of 302 kcal/kg with a relatively low ash content (Setyawan 2.
(Setyawan 2.
This calorific value meets the quality standards for biomass fuel.
Meanwhile, research by Lestari et al.
confirmed that Jabon also shows very promising characteristics for wood pellets, with a calorific value of 4,584 cal/g and a moisture content that meets international standards.
This finding is reinforced by research conducted by Nuryanti et al.
, who concluded that a mixture of Sengon and Jabon sawdust can produce wood pellets of good quality that meet the requirements of SNI 8021:2014 regarding wood pellets, particularly in terms of density and combustion value.
Research shows that the calorific value of wood pellets is often correlated with density, with higher densities generally improving combustion characteristics and efficiency, which are crucial for meeting these standards (Nuwa and .

With these characteristics, wood pellets from Sengon and Jabon waste are not only feasible to produce but also competitive in the national and international renewable energy markets as an environmentally friendly substitute for fossil fuels.
However, this vast and scientifically validated potential remains untapped by the Andalambe Forest Farmers Group owing to knowledge and technology gaps.
Farmers possess core cultivation skills but lack the understanding and technical skills required to process wood waste into economically valuable energy products.
From efficient waste management techniques and proper chipper technology to drying processes and knowledge of product quality standards and marketing, this complex and unfamiliar knowledge remains a challenge.
Without adequate technical assistance, this valuable harvest waste will simply end up as wood waste despite research demonstrating its high economic value.
Therefore, community service activity in the form of "Technical Guidance on the Utilization of Sengon and Jabon Logging Waste as Renewable Fuel is urgentl need ed.
This technical guidance program is designed to bridge this gap by providing practical knowledge and training to the farmers group based on existing scientific evidence.
Through this activity, it is hoped that farmers will not only be able to harvest their primary timber but also optimize the use of every part of the trees they have painstakingly planted.
By converting waste into a high-value renewable energy source, they are expected to increase the overall economic value of their forest farming business, support the principles of a circular economy, and contribute to environmental conservation, ultimately improving the sustainable welfare of the Andalambe Forest Farmers Group.
