Abstract. Dako FX, Purwanto RH, Faida LRW, Sumardi. 2019. Community’s social capital in the management of Mutis Timau Protected Forest in Timor Island, Indonesia. Biodiversitas 20: 2177-2187. The social capital of the community around Mutis Timau Protected Forest in Timor Island is unexplored. In fact, its social capital plays an important role to support sustainable management of the forest viewed from the ability of the community to work together in achieving common goals in groups and organizations. This study aimed to investigate the elements of community’s social capital (i.e. norms, beliefs, and networks) in nine villages located in and around Mutis Timau Protected Forest administratively managed by the Forest Management Unit of South Central Timor District using quantitative survey approach. The result of the study showed that two villages have strong social capital while seven villages have moderate category. Overall, the communities have strong level on the elements of trust in individuals and others, and knowledge and understanding on unwritten rules, but have moderate level on the elements of written rules/regulations, trust in institutions and regulations, organizational network, and participation network. Community participation increases the understanding of written rules, institutional trust and improves the development of social networks (organizational networks and participation) between groups. This results can be used as a reference for the Forest Management Unit of South Central Timor District when developing cooperation with communities that have traditional knowledge and local wisdom through norms, beliefs, and networks in managing and utilizing natural resources in Mutis Timau Protected Forest. Furthermore, the involvement of people with social capital in managing Mutis Timau Protected Forest can maintain forest sustainability and improve community welfare.

Abstract. Purwanto RH, Mulyana B, Satria RA, Yasin EHE, Putra ISR, Putra AD. 2022. Spatial distribution of mangrove vegetation species, salinity, and mud thickness in mangrove forest in Pangarengan, Cirebon, Indonesia. Biodiversitas 23: 1384-1392. The mangrove rehabilitation programs in the northern coastline of West Java showed varying levels of success due to the lack of information on habitat suitability and species distribution. This research aimed to investigate the spatial distribution of mangrove vegetation species, salinity, and mud thickness in Pangarengan mangrove forest, Cirebon, Indonesia. Data on mangrove vegetation, salinity, and mud thickness were collected from 78 randomly distributed sample plots. Species composition was analyzed using important value index, and spatial distribution was examined using QGIS. Results revealed that Rhizophora mucronata was the most dominant and widely distributed species in all areas of Pangarengan mangrove forest with the important value index (IVI) for seedlings, saplings, poles, and trees were 178.69%, 219.71%, 242.21%, and 167.56%, respectively. Avicennia marina showed significant IVI in saplings (59.41%) and trees (105.21%). Other species had an IVI of less than 20% for each growth stage. Salinity ranged from 0-28 ppt and gradually decreased from the shoreline to settlement areas. Mud thickness ranged from 55 to 175 cm but with no regular pattern observed. In conclusion, the Pangarengan mangrove forest was dominated by R. mucronata. Our findings suggest that to enhance the likelihood of success in mangrove rehabilitation programs, R. mucronata might be a good choice, but to increase the species diversity other species might need to be planted by applying specific treatments, such as a vertical aquaponic system.
