Environmental preservation is needed to develop the area. This is an area or area in which there is a living system of living things along with other elements of life namely air, water, and soil.
In big cities, environmental problems are not easy to overcome, such as air, water, and land pollution. The pollution occurs due to the conversion of the function of green land into company buildings, housing, and shopping centers. As in the city of Semarang, pollution is the main polemic. Indeed pollution occurs due to human behavior that does not pay attention to the preservation of nature in which he lives.

Logging in forests, disposal of garbage and waste into rivers, disposal of factory smoke into the air, conversion of green land into residential land are some examples of the causes of pollution.
The environmental pollution will certainly disrupt the ecosystems in it and will cause natural disasters, such as floods, landslides, or even drought. Therefore, it is necessary to hold education on environmental preservation by the government.
Environmental Conservation

Efforts and efforts to harmonize the environment to restore natural functions as they should are not only the responsibility of the government but also our responsibility. Actions and concrete actions that can be taken are as follows:
- Perform selective logging systems in the forest, by cutting down old trees. As well as the cutting system for planting, so when you cut you also have to plant new tree seeds.
- Reforestation and reforestation on critical land due to little or even lost nutrients so that the soil becomes barren and infertile.
- Regulate the irrigation and drainage system (drainage) properly and correctly.
- Using environmentally friendly goods.
- Sorting and processing waste to be more productive.
- Prohibit the disposal of factory waste into rivers, the sea, or the coast, because it will disturb the marine ecosystem.
- Defend protected forests
- Save the use of water, electricity, fuel oil.
Waste Management

The watershed functions to receive, store and then flow water through the river. If this management is carried out correctly it can improve the processing of dry agricultural land so that it can increase farmers’ incomes. Outside the agricultural sector, it functions as an irrigation facility and controls flooding.Socialization related to waste management Waste will be a productive item and has a sale value if managed properly.
Waste management can be done through a recycling process or commonly called recycle. Recycling is the process of turning a used item into a new item. Another benefit is that it can reduce pollution, soil damage due to littering, and air pollution from combustion. The recycling process includes sorting, collecting, processing, distributing and manufacturing products.
The benefit that will be obtained by holding an environmental preservation program is that the community will be more concerned about the environment.
Increase public awareness so as not to litter, but to reuse it by recycling it into new goods or compost fertilizer. Also, it provides information about the importance of protecting the environment from disasters. Awareness of the preservation of nature must start from oneself. Once the importance of the benefits of nature conservation for human life. What are you waiting for starting from small things, we create a sustainable nature!
