The Indonesian government has identified and secured funds aimed at restoring 600,000 hectares of damaged mangrove areas by 2021-2024 in 9 provinces, including the province of North Sumatra. This generated to the idea and the background for the activities of Professor Serving carried out by USU lecturers, namely by empowering the abundant former ponds in Tanjung Rejo Village, Percut Sei Tuan District, Deli Serdang Regency.

The Community Service Team Professor Serving, led by Prof. Mohammad Basyuni, S.Hut., M.Si., PhD (the Faculty of Forstry) with members Prof. Dr. Dwi Suryanto (the Faculty of Mathematics and Natural Sciences) and Ipanna Enggar Susetya, S.Kel, M.Si., (the Faculty of Agriculture), Fostered by three USU's Master of Forestry Program students (Yuntha Bimantara, Salma Safrina Harahap and Mikrajni Harahap), as well as five undergraduate students of USU's Forestry and Aquatic Resources Management Study Program, on July 21, 2021, carried out ecological and hydrological-based planting activities.

The activity involved Mugiono, a local resident who is the head of the fishing group, as the partner leader, who together with his members planted 2,000 Avicennia spp (api-api) seedlings, consisting of Avicennia alba, Avicennia marina. This community service activities also synergized with the research of 3 undergraduate students who examined the effect of restoration activities on changes in biota including crabs, arthropods, mollusks, and polychaeta, which were carried out before and after (3 months) after restoration activities.

Although it is recognized how restoration failures may have occurred in the past, there are no specific studies evaluating past restorations to guide future targets in an effective manner. Pak Mugiono Fishermen Group, when visited by the USU Community Service Professor, agreed when the abandoned pond was used for restoration activities and in the future it could be used for silvofishery ponds or used as a model for the success of mangrove restoration in former ponds.

This research includes the activities of measuring vegetation analysis, taking soil samples for analysis of nitrogen, phosphorus and carbon, measuring the physical and chemical properties of pond water. As a reference or standard is a natural mangrove forest that is adjacent to the location of the pond, as well as a pond that has natural regeneration of Avicenni seedlings next to it.

Service activities of Professor serving are expected to be a solution to partner problems and be the first step in using ponds for conservation activities, by restoring ecological and hydrological approaches, as well as being monitored regularly using water loggers and mini buoys.

The community service activity of Professor serving scheme is expected to contribute to restoration activities. It is also a model for the success of restoring former ponds that are not functioning properly, through improving water systems (pond gates) and fortifications as well as planting suitable plant species, namely Avicennia spp, measuring the success of restoration (before and after applying the ecological and hydrological approach).

One of the main motivations for mangrove restoration is to restore the high value of mangrove ecosystems for biodiversity and various ecosystem services such as coastal protection, fish product improvement, and other products that directly and indirectly benefit local and global populations. Deforestation has a negative impact on 16% of global mangroves of endangered species (Richards & Friess 2016 and reduced mangrove biodiversity and carbon storage in forest biomass (Polidoro et al. 2010; Simaliki et al. 2012). Mangrove conservation and sustainable mangrove management needed to maintain the existence of mangrove forests and improve rehabilitation and restoration programs. (©ULC)
