Belawan Harbour is located in Medan City, North Sumatra, Indonesia. The interaction between Belawan Harbour and the local community sometimes creates a controversy that can still be tolerated. The controversy is usually caused by the effect of activities in Belawan Harbour on the environment, which can be seen from social, economic and cultural aspects. Harbour Management did an observation of that component to recognize the rate of achievement of environment management which is carried out routinely every semester of year. The observation was done by conducting interviews using questionnaires to 70 participants. The research parameter is the advantages and disadvantages that local communities have. Participant determination was done by purposive sampling, by the distribution of 21.4% government apparatus, 7.14% public figures and 71.42% local communities. Based on the advantage aspect; the most dominant statement was; the economic improvement for the local area is 51.42% and working chances of improvement is 41.42%, meanwhile from the disadvantage aspect, the participants mostly stated that there was air pollution (50%) and noise pollution is 14.28%. %. In conclusion, the environment management done by PT Pelindo Regional 1 towards the Belawan Harbour operation is quite good, indicated by the high percentage of advantages in Belawan Harbour.

Mangroves are ecosystems within the intertidal zone of tropical and subtropical coasts; they offer ecosystem services such as protection from coastal erosion and storms and flood control, act as carbon sinks and are also sources of income by providing various forest products. However, their cover is rapidly disappearing worldwide, which makes the diagnosis and monitoring of the state of these important ecosystems, as well as their restoration and conservation, a challenge. Remote sensing is a promising technique that provides accurate and efficient results in the mapping and monitoring of these ecosystems. The Landsat sensor provides the most used medium-resolution images for this type of study. The main objective of this article is to provide an updated review of the main remote sensing techniques, specifically Landsat satellite imagery, used in the detection of changes and mapping of mangrove forests, as well as a review of climatic and/or chemical factors related to changes in the spatial distribution of these ecosystems.

Indonesia is a country with the application of agroforestry systems on community land. People who live in Toba Regency, North Sumatra have long applied coffee-based agroforestry systems and have become a hereditary tradition. The purpose of this study is to determine the profitability of coffee-based agroforestry land and economic value for farmers so that it can be developed further. Coordinate points of land distribution, taken with GPS, conducted interviews, profitability analysis and income analysis to obtain farmer land data. Mapping the distribution of farmers’ coffee-based agroforestry land was mapped with ArcGIS 10.8. Four respondent farmers implemented coffee-based agroforestry (Coffea arabica) with a planting distance of 2 m x 2.5 m combined with Gmelina arborea (white teak), Eucalyptus sp. (eucalyptus), Cinnamomum verum (cinnamon), Pinus merkusii (pine), Psidium guajava (guava), Durio zibethinus (durian), Persea americana (avocado), and others. Based on the profitability analysis, all four farmers’ lands are feasible for further development. The economic value of land depends on the area of land managed by the farmer, where farmers with a land area of 2 Ha have the largest income during 10 years of land management, namely Mr. Bisken with an income of IDR 162,719,500. Utilization of Multi-Purpose Trees Species (MPTS) or plantation and industrial crops can increase the economic value and profitability of farmers’ land.
