Mangrove forests are tropical coastal vegetation communities, which are dominated by several types of mangrove trees that are able to grow and develop in muddy coastal tidal areas. In order to preserve the biological and ecological functions of the mangrove forest ecosystem, a rational approach is needed in which a rational approach in its utilization involves communities around the area. Hamlet of Setingga Asin Sebubus Village, Paloh Subdistrict, Sambas Regency is one of the hamlets that has a mangrove forest area. The majority of the hamlet Setingga Asin people live as farmers, entrepreneurs and fishermen. People around the forest use it as additional livelihoods such as searching for shrimp, crabs, shellfish, kepah and nipah as the main ingredients for making roofs. The existence of the relationship between the community and the existence of mangrove forests raises the perception of the community in an effort to maintain and preserve the existence of the mangrove forest itself. Therefore, this study aims to determine the public perception of the existence of mangrove forests in Hamlet of Setingga Asin, Sebubus Village, Paloh Subdistrict, Sambas Regency and to know the factors that influence people's perceptions. The study used a survey method with interview techniques for 73 family heads in Hamlet Setingga Asin. Sampling of respondents is done by purposive sampling technique. The data analysis used was descriptive analysis and inferential analysis of the Kendall Tau correlation. The results showed that community perceptions of the existence of mangrove forest in hamlet Setingga Asin, Sebubus Village, Paloh Subdistrict, Sambas Regency tend to be neutral, this is because the community basically realizes that they depend on the surrounding mangrove forest's biological resources. However, the community does not understand that these resources need to be managed sustainably so that the benefits can be obtained sustainably.Keywords: community perception, conservation, mangrove, utilization.

Arboreal ants are ants that do activities and spend their lives in tree. Roles of this organism are to serve as decomposers, pollinators, predators and indicators. Ant species diversity constitutes a chain for ecosystem stability. They are responsible as decomposing insects making their presence becomes ecologically vital. Research on ant species diversity in mangrove forest remains insufficient. One of the reasons possibly is that fact that mangrove is an ecosystem which is affected by sea tide. This research aims at gathering data about ant species diversity based on types of mangrove forest vegetation located in Setapuk Besar, Singkawang City. The research used a survey method by observing types of trees whose diameter was 10 cm and above. Additionally, the tree should have a large number of ants. The data was collected through fly sheet trap set under, in the mid, and above the tidal level. Findings revealed 6 types of ants consisting 4 sub-families in 6 types of the trees i.e. Rhizopora mucronata, Avicennia lanata, Hibiscus tiliaceus, Terminalia capatta, Nypa fruticans, and Bruguiera cylindrical.. Based on the diversity index of those 6 types of trees, the divercity of arboreal ants spesies could be categorized low (H’<1). The highest diversity was nypa fruticans vegetation by 0.325. This was because the tree contains sugar level and carbohydrate. The lowest diversity was Hibiscus tiliaceus and Termialia catappa. The H’ value was 0. One of the reasons was because only one species of ants can be found in both trees, namely Oecophylla smaragdina.Keywords: Arboreal Ants, Diversity, Mangrove, Singkawang
