The International Science and Innovation Fair
The Indonesian Young Scientist Association (IYSA) Indonesia organised an international-level Invention competition called “International Science and Invention Fair (ISIF)" as the learning platform to nurture our young talented scientists and inventors who are active, creative and innovative.
About IYSA
Indonesian Young Scientist Association (IYSA) collaborating with Indonesia International Institute of Life Science (i3L) organized the FIRST ever International Science and Invention Fair at Bali Creative Industry Center, Bali, Indonesia. With more than 100 teams came to participate, ISIF was definitely the highlight of the year.
Through ISIF, we would like to give a place for young scientists from around the world to show off their invention and projects in science fields. Because we believe that young scientists are the beacon of hope for the future.
This event was joined by multiple countries such as Germany, Turkey, Turkmenistan, Thailand, Philippines, Vietnam, Malaysia, and of course, Indonesia. It was a melting pot of diversity and creativity, place where we can express ourselves.
OBJECTIVIES OF ISIF 2020
• Making innovation events to develop the creativity spirit in International students.
• Developing the skills of scientific research and the spirit of innovation among International students.
• Exchanging innovation and invention experiences through friction between students around the world.
SST is represented by the following teams and the corresponding results:
Measurement of The Mass of Jupiter (GOLD MEDAL + Scholarship)
Nguyen Ngoc Bao Tram (S3-05), Gan Sim Ru Dayna (S3-07)
Jupiter is the largest planet in the solar system as it is approximately 143,000 kilometres wide at its equator. It is the fifth planet from the Sun, and surprisingly one of the brightest planets in the sky. The studies from Nicolaus Copernicus has helped Johannes Kepler to study the orbit of the planet around the Sun. In this project, the goal is to seek for the knowledge and the understanding of how the physics laws are applied to help future exploration of space. With the extensive research, it is hoped to extend to the measurement of the mass of other planets and the discovery of new planets. It will also contribute to the study of life’s big questions such as how the solar system looked like before then.
The big idea is to use planetary photography and Jupiter's moons to find the mass of Jupiter. The observation of the planet, Jupiter, and its four Galilean moons has assisted in the calculation the distance between the moon and Jupiter and how much it changes over time. Thus, it enables the usage of Kepler’s Third Law to find the mass. To determine the mass of a stellar body like Jupiter, the process uses simple gravitational physics. Therefore, the mass of Jupiter can be found using Kepler's Third Law. The calculated mass of Jupiter is 1.898E+27 kg with a 3% error in comparison with the value of 1.898 x 10^27 kg which is found on the Internet.
Investigation of Algae as a Biofuel (SILVER MEDAL)

Algy aims to replace non-renewable energy sources with a new, efficient, renewable and sustainable source of energy. With Algy, our own source of energy does not have disadvantages such as lack of sustainability and having adverse effects on land and marine life as compared to fossil fuels. Instead, Algy relies on the energy potential of algae, and at the same time reducing carbon emissions. Algae are small organisms that convert sunlight into energy where some store this in the form of natural oils. Algae can produce a lot of energy which can be converted to biofuels. After extracting the oil, the raw materials can be used to make fuel for vehicles. We aim for this product to be able to reduce or even eliminate the carbon dioxide in a closed environment and produce enough energy. This would help the world progress as it grows with the use of technology with minimal or without harming the Earth. With these objectives in mind, we can scale our product and hopefully progress the Sustainable Development Goals closer to completion.
Investigation of the Colour Changes of Clitoria ternatea in Different pH Conditions (BRONZE MEDAL)
Nur Aliah Binte Adam Poh (S3-04)
Why is Clitoria ternatea blue, and why does it change colour in different pH? This research is hence conducted to investigate more about colour changes of Clitoria ternatea in different pH conditions. Under this overarching theme of colour changes of the Clitoria ternatea, research has also been held on the determination of the presence of anthocyanins in Clitoria ternatea and the findings of different type anthocyanins that could be found in the Clitoria ternatea too. The hypothesis is that there is a presence of anthocyanins in 6 different varieties and the colour changes of the Clitoria ternatea solution are red in an acidic solution which transits to purplish to blue to green in mildly alkaline solution to yellow in a very alkaline solution. Results obtained were that there was the presence of anthocyanins. However, five out of six anthocyanins were attained. Additionally, there were slight colour changes from red in an acidic solution to purplish to blue to green in a mildly alkaline solution to yellow in a very alkaline solution. In conclusion, Clitoria ternatea has anthocyanins which enable colours to change vibrantly due to the unique molecular structure of different anthocyanins present.
