Keren! Inovasi Siswa SMA di Semarang Raih Emas di Kompetisi Teknologi Internasional

Introduction

This tutorial provides a detailed guide on how a group of high school students in Semarang, Indonesia, developed an innovative water purification device that won a gold medal at an international technology competition. The steps outlined will help you understand the process of creating a similar water purification system, as well as the importance of innovation in addressing environmental issues.

Step 1: Identify the Problem

• Understand the need for clean water in your community.
• Research local water contamination issues, including sources of pollution.
• Gather data on the impact of contaminated water on health and environment.

Step 2: Conceptualize the Solution

• Brainstorm ideas for a water purification device.
• Consider various filtration methods, such as:
  • Sand filtration
  • Activated carbon filtration
  • UV purification
• Discuss the importance of creating a device that is both effective and user-friendly.

Step 3: Design the Filtration System

• Create a layered filtration system that includes multiple types of filters.
• For example:
  • First layer: coarse filter for large particles.
  • Second layer: sand or gravel for finer particles.
  • Third layer: activated charcoal to remove contaminants and improve taste.
• Ensure that the design allows for easy maintenance and replacement of filters.

Step 4: Integrate Smart Technology

• Add sensors to monitor the purification process.
• Implement a feature where an indicator light turns on when the filtration is complete.
• Explore options for a simple display showing water quality metrics.

Step 5: Prototype the Device

• Gather materials needed for building the prototype, such as:
  • Plastic or glass containers for the filtration system.
  • Various filters (sand, activated charcoal, etc.).
  • Electronic components for the sensor and light indicator.
• Assemble the components according to your design.

Step 6: Test and Evaluate

• Conduct initial tests with local water samples.
• Monitor the effectiveness of the filtration system in terms of clarity, taste, and safety.
• Make adjustments to the design based on test results.

Step 7: Prepare for Competition

• Document the design process, testing results, and the impact of your invention.
• Create a presentation that highlights the innovation and its benefits to the community.
• Submit your entry to competitions like the Malaysia Technology Expo.

Conclusion

The journey of creating an effective water purification device not only addresses a critical need but also fosters innovation and teamwork among students. By following these steps, you can develop a solution that contributes to clean water access in your community. Consider participating in local or international competitions to showcase your work and gain recognition for your efforts.
