Climate change causes an increase in waves and abrasion, damage to mangrove forests on the coast of Labu due to abrasion has an impact on the balance of coastal ecosystems. Mangrove forests function as breakwaters and abrasion resistance, spawning areas for marine life. This condition has an impact on the productivity of marine biota, the environment so that it will affect the community's economy. This community service aims to increase knowledge, skills and awareness of coastal communities in environmental management, especially mangrove conservation in overcoming abrasion, improving community values and changing behavior so that they can take an important role in climate change mitigation efforts. The method used is socialization, community development, mentoring and community organizing in environmental management through community service "Climate Change Mitigation through Real Actions of Restoration Generation for Mangroves on Pantai Labu". The expected target and outcome is the improvement of environmental quality, knowledge and skills of the community as coastal environmental managers. Publications in journals, videos and mass media, produce processed mangrove products as well as IPR drafts. Community service activities include planting mangroves on coastlines that have experienced heavy abrasion, maintaining and restoring coastal areas with coastal reforestation mitigation activities, processed food products from mangrove plants and the formation of youth organizations that care about the environment

Bogak Village is a coastal village with a waste problem that can contribute to climate change. Instilling waste management knowledge needs to be done with the appropriate method. The purpose of the activity was to apply the Atteropoly game as an early education means regarding waste management for elementary school-age children in efforts to mitigate and adapt to climate change in Bogak Village. The stages were planning and preparation (gathering information on partner problems and compiling educational game instruments), implementation of service activities, and monitoring evaluation. Educational activities through the Atteropoly game were directly carried out on July 6, 2022 to 30 participants of elementary school-age children and two teachers from the Rumah Qur’an Miftahul Jannah. Measuring the success of Atteropoly media used pre-test and post-test, it was found that there was an increase in participants’ knowledge and the average score of 38,33 (pre-test) to 53,00 (post-test). It can be concluded the Atteropoly game increases the elementary school-aged children’s knowledge in Bogak Village. The community service team also gave a set of Atteropoly game tools and segregated trash bins to the village. It is hoped that the Atteropoly game tool can be used to educate the public, especially elementary school-age children in Bogak Village.

The widely spread of the Dengue Haemorhagic Fever (DHF) in North Sumatra made a field work study on this topic was very important. It was reported that the Dengue Haemorhagic Fever (DHF) is an acute fever in 2 until 7 days with two or more manifestations such as headache, retro-orbital pain, mialgia, atralgia, skin rash, and haemorhagic manifestation. A case study of the Community Based Control was carried to know the responsible factors of the widely spread of DHF and the way of controlling its by applied Comunity Based Model. This study basically sought the influential factors of the widely spread of DHF such as rainfall, air humadity, air temperature, and wind velocity that might be possible to be anticipated by Community and government. Thus, the effectiveness of Community Based Controlling Model was also presented. The combination of recorded cases and a field observation was proceeded to the liniar regression test; so it was known that there was an association between air temperature and DHF case in Binjai Municipality 2011-2015 because the p value was 0,038 (p < 0.05). The association between wind velocity and DHF cases showed a strongly significant association (r = 0,899) and patterned positively.it is necessary to eradicate the mosquito breeding place in a high number of DHF case.
