“The idea came from the students, while the equipment was made by the parents of the students,” said Wayan Murdana, Thursday (1/10). This tool principally uses the water gravity force that is collected in the tube, while the water and soap flow uses foot pressure. So, this tool allows the feet to distribute water in the tap and soap. According to Murdana, this tool is very water efficient and the waste is processed again through filtering so that it can be used to water school plants.

The teacher also prepared online teaching and learning process facilities for each class. However, if teachers feel that their immunity is weakened, they are not required to teach from school. Students are also prohibited from going to school because it can create a crowd.

Students who do not have online resources are provided for free at school by implementing strict health protocols. Meanwhile, teachers and the community who go to school are handled directly by the Spentri Covid-19 Task Force.

Not only will the Covid health program be continued, Murdana added that the online teaching and learning process model will also be used as a model for continuous learning. If in the new normal era, schools were allowed to hold limited face-to-face teaching and learning processes, he had also prepared a special curriculum and strategy.
