Kampung Nelayan in Medan Belawan Sub-district is a coastal community whose lives are highly dependent on local resources, namely mangroves and their waters. Mangroves in the area are very potential as mangrove tourism sites, but in some areas have been damaged. Therefore, it is necessary to carry out mangrove restoration activities by making local communities the main actors. Mangrove restoration activities can also be juxtaposed into mangrove ecotourism attractions as has been done in Sei Nagalawan, in Serdang Bedagai Regency. (Onrizal et al. 2016).

Mangrove restoration is currently not an activity that gets the attention of the community in Kampung Nelayan, Medan Belawan. Even though these activities are very helpful in restoring environmental conditions and coastal biota populations, so that in the long run they can support the welfare and health of coastal communities. Therefore, one of the service activities in the Assisted Village Program is mangrove restoration with the community of Kampung Nelayan, Medan Belawan by paying attention to ecological, social and economic aspects.

Nursery activities that produce good quality seedlings can be a new source of income for the community because of the large number of rehabilitation activities by various parties in the east coast of North Sumatra, while the availability of seedlings is limited. The east coast of North Sumatra has lost about 60% of its mangroves due to various human activities (Onrizal, 2010). So many mangrove seedlings are needed, so the opportunity, mangrove nursery as a new source of income becomes very promising.

The purpose of this assisted village service activity is to empower community groups in restoring mangrove ecosystems and increasing the added value of mangrove planting activities through nursery businesses. This activity is useful for restoring mangrove ecosystems in state forest areas, increasing community capacity in mangrove seedling cultivation and increasing the role of the community in preserving mangrove ecosystems in Kampung Nelayan Seberang Medan.
