Abstract

Carbon reserves in forests play a crucial role in climate change mitigation and the preservation of global ecosystems. Forests act as primary absorbers of carbon dioxide (CO2) from the atmosphere, storing carbon in the biomass of trees, soil, and leaf litter. This community service aims to provide understanding and education to the public about carbon storage, factors influencing storage capacity, and the implications of sustainable forest management. The methodology used includes direct measurement of carbon reserves in various forest types and the analysis of secondary data from scientific literature. Survey results indicate that the village forest of Wapkalit still has significant potential, emphasizing the need for community awareness to continue managing and preserving the forest. Socialization conducted through the FGD (Focus Group Discussion) method can directly impart knowledge to the community.

Abstract

This study aims to examine the forms of local wisdom in managing dusung-based agroforestry in Negeri Mamala, Leihitu Sub-district, Central Maluku Regency, as well as to explore its underlying socio-cultural values. The research employed a qualitative method with purposive sampling, involving 30 respondents from five Soa groups, along with key informants such as traditional leaders, village officials, and Soa heads. Data were collected through observation, interviews, questionnaires, literature review, and documentation, and analyzed using the interactive analysis model of Miles and Huberman. The findings reveal that local wisdom in dusung management is reflected through the practices of Sasi and Matakau, which function to conserve natural resources and prevent crop theft. Respondents’ assessment of three local wisdom variables (adaptive-dynamic, harmony with nature, and sustainability-oriented) indicates that the sustainability orientation scored the highest at 40.72% (1,789). Furthermore, the socio-cultural values of the community are embodied in traditional practices such as Bambu Gila, Pukul Sapu, Latupati, and Pela Gandong alliances, which strengthen social solidarity and environmental conservation. This study highlights that dusung management provides not only economic benefits but also cultural preservation and ecological sustainability.

Abstract

This study aims to compare the results of carbon stock (C-stock) calculations in sago palms using destructive and non-destructive methods, as well as to determine the starch yield of sago palms (Metroxylon sagu.) in Tulehu Village, Salahutu District, Central Maluku Regency. The study was conducted on five sago palms selected based on their size and growth phase, using a purposive sampling technique. The destructive method involved felling and weighing the actual biomass, while the non-destructive method used an allometric equation with parameters such as diameter, tree height, and wood specific gravity. The results showed that the destructive method produced an average carbon stock of 0.31 tons per tree, while the non-destructive method only produced 0.14 tons per tree, with an average difference of 0.17 and a deviation of 61.34%. This confirms that the non-destructive method tends to underestimate the actual value, so the destructive method remains more accurate and can be used as a basis for validation. Estimation of starch yield shows that one mature sago palm with a wet pith weight of 928 kg has the potential to produce 120.64–148.48 kg of dry starch and a yield of 13%–16%.
