Our Fieldtrip
To gain more information, we interviewed a couple of resources to support our inquiry.
Not far from our school, there’s a densely populated residential area affected by flooding. It suits our profile. We interviewed Bapak Yasin, the head of RT 09, to ask about the area’s history before the land converts into residential. We also asked about the flood that occurs in the place.
Dinas Cipta Karya, Tata Ruang, dan Pertanahan
Land conversion has become the nation’s responsibility since it is one of the urban development processes. The government also has an essential role in controlling and supervising the continuously converted land. To learn more about how they regulate and control the issue, we interviewed Bapak Herry, who worked at Dinas Cipta Karya, Tata Ruang dan Pertanahan division.
Land conversion can cause a lack of environmental ecosystems such as plants and soil. Plants keep dirt in place, and their roots soak up water. Concrete doesn’t do much to stop or soak up rain during heavy rain. Plants and soil, however, can act as a sponge absorbing water level raising. Plants can prevent flooding and lessen damage as well.
To show the ability of soil to absorb water, we experimented with two different environments. We designed the environment in separate boxes.
Experiment
The first box is designed to show natural land without conversion. It is filled with only soil and plants.
The second box is designed to show the land after conversion. It is filled with soil, a few plants and types of cement on the top of the soil. We even added mini houses to replicate the same environment converted into a residential area.
We poured water into the box within three days in exchange for rainwater. We differentiate the volume of water for each day.
Day 1: 300 ml (light rain)
Day 2: 600 ml (medium rain)
Day 3: 1000 ml (heavy rain)
We observed how each environment absorbed the water depending on the soil condition.

Mentoring
We decided to take participation action. Participation was when we made Biopori in the school environment. We made five bio-pores spread in school areas often affected by floods.
