Abstract

Mangrove ecosystems contribute to biodiversity conservation and climate-change mitigation through carbon storage. This study assessed the association between biodiversity (flora and fauna) and carbon stocks in mangroves of North Sulawesi across three management contexts: a conservation zone (Bunaken), a protected forest (Sondaken), and an unprotected area (Bitung). Field surveys were conducted to compile species inventories, and carbon stocks were estimated from biomass measurements. Protected sites showed higher species richness and larger carbon stocks than the unprotected site. Species richness was positively and significantly correlated with carbon storage, indicating that sites with greater biodiversity also tended to store more carbon. These results support the role of effective protection in maintaining both ecological integrity and carbon sequestration capacity. In conclusion, strengthening mangrove protection in North Sulawesi is likely to deliver co-benefits for biodiversity conservation and climate mitigation.

Abstract

Woka (Saribus rotundifolius (Lam.) Blume.) is a palm tree that has significant ecological and socio-cultural value for the community of Bolaang Mongondow. However, local knowledge about its use and characteristics is threatened by extinction due to modernization. This study aims to: (1) identify the morphological characteristics of the woka plant, and (2) document the forms of utilization based on the local wisdom of the community of Bolaang Mongondow in managing woka. This study used qualitative methods with an ethnobotanical approach. Data were collected through field observations, in-depth interviews with key informants (traditional leaders and craftsmen), and documentation studies. The results show that woka has distinctive morphological characteristics, such as round fan-shaped leaves (rotundifolius) and strong stems. Woka has a wide range of uses, especially its leaves, which are used as roofing material for traditional houses (baloi), woven crafts for traditional ceremonies, and as food wrappers. Local wisdom is reflected in the knowledge system of sustainable harvesting techniques, traditional rules of harvesting, and beliefs that support the preservation of woka. It is concluded that woka is not just a plant but an integral part of the local cultural identity and ecosystem. This documentation is expected to serve as a database for the conservation and sustainable development of the economic value of woka.

Abstract

Mitra Program Kemitraan Masyarakat (PKM) ini adalah masyarakat Kelurahan Winangun Dua Kecamatan Malalayang Kota Manado. Masalah mitra adalah ancaman menurunnya keanekaragaman hayati dalam lanskap pemukiman akibat terbatasnya ruang terbuka hijau (RTH) dan tingginya stres lingkungan diantaranya yang disebabkan polusi. Hal ini terkait juga dengan masih rendahnya pengetahuan dan keterampilan yang memadai mengenai pemanfaatan keanekaragaman hayati dalam lanskap pemukiman.  Tujuan pelaksanaan kegiatan PKM ini yaitu memberikan penyuluhan kepada masyarakat tentang pengelolaan lanskap pemukiman yang tepat untuk melestarikan sekaligus memanfaatkan keanekaragaman hayati. Solusi yang ingin dicapai adalah 1) meningkatkan pengetahuan beragam vegetasi dan desain lanskap pemukiman kawasan perkotaan untuk mendukung keanekaragaman hayati dan meningkatkan apresiasi dan motivasi untuk berkontribusi (luarannya adalah perbaikan tata nilai masyarakat yaitu pendidikan) dan 2) meningkatkan keterampilan pemanfaatan dan pelestarian keanekaragaman hayati di lanskap pemukiman dengan memberikan demo beberapa tindakan praktis pemilihan vegetasi dan aplikasi desain lanskap pemukiman (luarannya adalah peningkatan penerapan IPTEK di masyarakat dalam hal ini manajemen). Lebih spesifik lagi, melalui penyuluhan Tim Pengusul memperkenalkan beragam vegetasi dan desain lanskap yang cocok untuk pemukiman perkotaan. Pelaksanaan penyuluhan dalam PKM ini terdiri dari ceramah, tanya jawab, dan demonstrasi dengan pelibatan peserta secara langsung. Secara lebih terperinci, tahapan pelaksanaan kegiatan penyuluhan yaitu : a) Tahap peningkatan kesadaran (awareness); b) Tahap peningkatan minat (interest); c) Tahap peningkatan kemampuan menilai (evaluation); d) Tahap stimulasi untuk mencoba (trial). Kegiatan PKM ini memberikan dampak positif berupa meningkatnya pengetahuan, kesadaran, dan keterampilan masyarakat dalam pengelolaan lanskap pemukiman yang mendukung pelestarian keanekaragaman hayati.    Kata kunci: Keanekaragaman hayati, lanskap pemukiman, pendidikan lingkungan, pengelolaan lanskap, penyuluhan.   ABSTRACT The community partner for this Community Partnership Program (PKM) is the residents of Winangun Dua Village, Malalayang District, Manado City. The partner's issue revolves around the threat of declining biodiversity in residential landscapes due to limited green open spaces (RTH) and high environmental stress, including pollution. This is also related to the still low level of adequate knowledge and skills concerning the utilization of biodiversity in residential landscapes. The objective of this PKM activity is to provide education to the community on the proper management of residential landscapes to conserve and utilize biodiversity. The solutions aimed to be achieved are 1) increasing knowledge of various vegetations and urban residential landscape design to support biodiversity and enhance appreciation and motivation to contribute (the outcome being the improvement of societal values, namely education), and 2) enhancing skills in utilizing and conserving biodiversity in residential landscapes by providing demonstrations of practical actions in selecting vegetation and applying residential landscape design (the outcome being the increase in the application of science and technology in the community, specifically in management). More specifically, through educational outreach, the Proposing Team will introduce various vegetation and landscape designs suitable for urban residential areas. The implementation of educational outreach in this PKM involves lectures, question-and-answer sessions, and demonstrations that engage participants directly. The detailed stages of the educational outreach activities are a) Awareness-raising stage; b) Interest enhancement stage; c) Evaluation skill improvement stage; d) Trial stimulation stage. Keywords: Biodiversity, residential landscape, environmental education, landscape management, outreach.
