Abstract

Carbon conservation programs in mangrove ecosystems focus on the growth of mangrove vegetation that is measured based on the amount of carbon present at different tree stages particularly, the seedlings, saplings and mature mangrove trees. This study was aimed to determine carbon percentage of mangrove ecosystems using the SNI 06 – 3730 – 1995 and TAPPI T 211 om 85 methods, and to analyse the mangrove clustering based on carbon percentage. The  results showed that (1) Avicennia spp, Sonneratia spp, Bruguiera spp, Rhizophora spp, Aegiceras spp, Lumnitzera spp, Ceriop spp, Exoecaria agallocha and Xylocarpus granatum had carbon percentages between 45.01-55.54%; (2)  the carbon percentage of mangroves at different growth stages were as follows; seedlings at 16.3-21.2%, sapling at 19.0-28.1%, trees with diameter at breast height (DBH) of 10-20 at 38.1-46.3%, trees with DBH of 20-30 cm at 40.2-51.1% and trees with DBH of 30-40 cm at 49.1-55.2%. The carbon conservation is positively correlated with the carbon sequestration ability and growth of the mangroves.

Abstract

Community forest management are individualized according the decision of the land owners and yet have a standardized manage-ment method. Characteristics of community forest have a high diversity at the level of the land owners. Community forest sustainability can be seen from the forest stand structure. The aim of this study was to obtain horizontal stand structure model and compile yield regulation method for each community forest land ownership. Information of the community forest stand in the Cidokom Vil-lage, Rumpin District obtained exploratively and preparation of the yield regulation method analyzed descriptively.  Sample of sub-districts, villages, and community forest owners was determined by purposive sampling by considering the potential of community forests, technical convenience in the field, accessibility of research locations, and representation of land area data in community forest land ownership groups. From negative exponential function at community forest, obtained “k” values ranges between 39.71–2318.99 and “a” values ranges between -1.58–0.01. The results showed that the stand structure of each land owners of community forest varies and yield regulation method can be used by the community forest landowners which can be adjusted with the cutting decision and land contition to achieve community forest sustainability.

Abstract

Nilai ekonomi total ekosistem hutan berasal dari berbagai jenis hasil hutan, mencakup hasil hutan kayu dan non kayu, termasuk juga jasa fungsi ekologis. Pendekatan sistem digunakan di dalam pendugaan nilai ekosistem hutan, dengan dasar pertimbangan adanya karakteristik saling keterkaitan berbagai hasil hutan tersebut. Pada umumnya, masing-masing pihak atau stakeholders mempunyai penilaian yang berbeda-beda tergantung pada persepsi dan kepentingan masing-masing pihak. Tujuan penelitian ini adalah menjawab pertanyaan bagaimana mengukur dinamika nilai ekonomi total ekosistem hutan, dan bagaimana cara mengharmoniskan berbagai kepentingan stakeholders itu di dalam pengelolaan hutan. Hasil simulasi dengan intensitas penebangan tegakan 0%, 50%, 76% dan 100% menunjukkan bahwa nilai ekonomi total (nilai guna kayu dan non kayu) tidaklah statis, tetapi nilai ini dipengaruhi oleh perubahan kondisi ekosistem hutan, sebagai akibat tindakan pengelolaan hutan. Harmonisasi kepentingan stakeholders di dalam pengelolaan hutan dapat dievaluasi melalui distribusi nilai ekonomi total, dan pemenuhan kriteria kelestarian sumber daya hutan, yang di dalam simulasi penelitian ini dapat dicapai pada intensitas penebangan tegakan 50%.
