Tokyu Land Indonesia did the 5^th CSR on 2018 at Gunung Mas, Puncak with the theme “Save Trees, Save Our Earth.” As part of environmental conservation and supporting the government’s efforts to increase water catchment areas and conserve groundwater in various regions in Indonesia, PT Tokyu Land Indonesia has again planted trees, that this year is located in the Gunung Mas, Puncak, West Java. The location of Puncak was chosen because Puncak is a highland, not only for the West Java area itself, but also for the Jakarta Metropolitan area. Planting this tree has an impact on reducing erosion and increasing water catchment areas, so it is hoped that it can reduce landslides and rainwater can be well absorbed into the ground and provide benefits both to the surrounding community and the Jabodetabek community. Consistently, TLID continues to make an active contribution to the environment and society so that its impact can be felt directly by them. In collaboration with the government and local community institutions, it is hoped that we can continue to have a positive impact on the lives of Indonesian people every year.
