Wednesday, April 22, 2020 is celebrated as World Earth Day. The day is celebrated at all countries in the world with a variety of different activities. Of course with that purpose the same is to protect and care for the earth so that it is not getting damaged and getting better.
Society when faced with various disasters or environmental problems such as floods, landslides, droughts and forest fires will suffer material losses as well human victims. Based on this the international community has agreed the importance of protecting the earth from pollution and damage in order to face challenges environment on earth.
Knowledge about the importance of protecting the environment needs to be improved for everyone. This needs to be done to realize what are the impacts on us does not protect the earth. Efforts that humans can do to protect the earth can be done through the implementation of environmental education. Movement that can be done every day like planting trees, recycling waste, reducing pollution by cycling and not littering. Developing a community for environmental awareness is expected to be effective at convey through school environment education. As a place of learning, schools can help students to understand the impact of human behavior on earth as well as the importance of the earth as a place of sustainable living. Therefore, the importance of understanding about guarding the earth must be implanted in everyone since childhood. Keep the earth healthy.
Adria Pratama Mulya High School (SMA) Tangerang is a school that supports the movement to preserve environment. With an area of 7.6 hectares, this area is overgrown with green trees and lush. With the addition of a curriculum on the environment, it is hoped to bring positive impact on all students so that they can emphasize keeping and caring for the environment is the duty of all of us. Some application of environmental programs life includes:
1. Planting Trees
This activity is routinely carried out by high school students Adria Pratama Mulya High School (SMA) Tangerang. This activity besides aims to preserve the environment, planting trees also has an impact very good for the environment. As we know, other than as a place for saving ground water reserves, planting trees can also prevent disasters such as floods and landslides for the surrounding environment.
2. Recycle waste
Creativity is a combination of critical attitude and sharpness of the idea of creating. The existence of "garbage" resulting from KBM activities one of which is used writing paper, students and teachers claimed to be responsible for resolving it
"Project DIY Upcycle with Cement" is a creative solution to deal with the paper waste. Through Entrepreneurship subjects, class XII students collaborate "DIY Cement" skills based on upcycle and recycle techniques with environmental material on "ornamental plants as agents for controlling air pollutants".
3. Making Biopori Holes
Biopori infiltration holes are cylindrical holes that are made vertically into the soil as a water catchment method aimed at overcoming puddles by increasing the water absorption capacity in the soil. Biopori has a myriad of ecological and environmental benefits, namely expanding the field of water absorption, as handling organic waste, and improving soil health. With the biopori hole, it is expected that groundwater reserves in the area around Adria Pratama Mulya High School (SMA) Tangerang will still be there even though it is entering the dry season.
4. Planting Using Hydroponic Media
Limited land for farming does not become an obstacle to being able to maintain environmental quality. Through the hydroponic method, this activity is very exciting to do. Hydroponics is a cultivation plant by using water without using soil and emphasizing the growing nutritional needs for plants. The need for water in hydroponic plants is less than the need for water in aquaculture using soil media. Hydroponics uses water more efficiently, so it is very suitable to be applied in areas that have limited water supply. Some plants that can be planted include water spinach, mustard greens, watercress. Planting is carried out for approximately 2 weeks in order to be able to harvest
5.Vegetable and Medicinal Plants
The activity of growing vegetables and medicinal plants is almost done once a month. This activity begins with nurseries. Good seeds that are selected have signs such as, free from pests and diseases, have a high growth ability, have a germination capacity of about 80%, and have a healthy and productive parent history. Based on the type of plant, there are several treatments before the seedlings are sown or which can be directly sown. Nursery techniques that must also be considered are the adequacy of plant nutritional needs. During the nursery period, seedlings need adequate water intake, adequate fertilizer, and prevention of intruding organisms.
After breeding, the seedlings must be moved to permanent land. The land must first go through various tillage processes as preparation. The process of processing land is done by loosening the soil and making sure the land is in accordance with the conditions for growing plants to be planted. For example adjust the pH and water content. In carrying out fattening, farmers can hoe the land in an ordinary way and evenly distributed.
As explained before, before planting need to be ascertained whether the plants to be planted need to be sown or not. If necessary, do seeding and if not proceed to the planting process. In the case of planting, which need to be considered is the distance of planting. The ideal planting distance is one of the factors that determine the success of plants to grow. Plants planted include red chili, cayenne pepper, galangal, lemongrass, and red ginger.
