Volcanic activity in Indonesia sometimes causes eruptions accompanied by volcanic ash, which causes a decrease in air quality in the area around the mountain. The decrease in air quality by volcanic ash is caused by chemical gases such as CO, NO2, and SO2, so any long exposure to volcanic ash may cause acute respiratory infection (ARI). Unfortunately, the N95 masks that the public has used have not effectively filtered volcanic ash less than 300nm in size. In addition, the polymer content made from plastic in N95 masks is prone to waste that is difficult to degrade naturally.

The Covid-19 pandemic has exposed children to gadgets such as computers, laptops, and cellphones more intensely due to distance learning. Gadgets for learning are also followed by the increasing use of gadgets for social media and online games that trigger gadget addiction. To reduce this problem, UNY students consisting of Dwi Agnes Setianingrum, Dian Anggraini and Akhip Nugroho (science education), Furi Ningsih Sri Sukowati (physics education), and Aerafatma Ahyaun Nisa (elementary school teacher education) initiated the development of a traditional game.

UNY students made a wallet with a security system that will inform the owner when the wallet is more than 10 meters apart from its owner. Uniquely, the wallet is made of banana midrib fiber, given a Javanese letter pattern. They are Asni Muslimah (Clothing Engineering Education), Annisa Nurfatimah Febrianti (Accounting Education), Annisa Alimah Ufairoh (Physical Education), Latifah Nur Khasanah (Chemical Education), and Atiqotul Maula Al Farihah (Sociological Education). According to Asni Muslimah, they made the smart wallet because many people still use conventional wallets.

Anthony Fioren H, Mohammad Damarjati P and Syukron Abdul A succeeded in making an age detection application through facial photos. Anthony Fioren stated that they used training data in image data of a human face with age information from the face to train a computer to recognize the age and gender of a human face. "To determine gender and age from the image, we use algorithms and digital image processing methods," he said. It works to extract parts of the human face in the image and then process it so that the output issued is the age and gender.

The Department of Civil Engineering Education and Planning, Faculty of Engineering, Yogyakarta State University (FT UNY) team became Cinnertion's Favorite Champion in the D'Village 10th Edition held by the Surabaya Institute of Technology (ITS) (02/06– 31/10/2021). The team consists of M. Fajar Amir (Civil Engineering Education and Planning), Novarida Nurul Sabrina (Applied Bachelor Civil Engineering Study Program), and Raden Rara Bintang Permata Hati (Civil Engineering Education and Planning Study Program) supervised by Qonaah Rizqi Fajriani, M.Eng.

The need and demand for electricity in Indonesia are significantly increasing, yet the supply of energy sources is diminished. Concerning the issue, water can be a potential resource to be utilized as alternative energy. However, the use of water as alternative energy has not been used optimally. This is what prompted a group of UNY students to invent portable hydroelectric power plants that can meet electricity needs, especially in rural and remote areas.

The UNY students team has presented “Nanocomposite ZnO/Carbon Dots Cassava Outer Shell as a Photocatalyst for Methylene Blue Dyes Waste Degradation” at the World Youth Invention and Innovation Award (WYIIA) 2021. Their presentation has succeeded in convincing the judges to give award silver medals.

Drowsiness is the second highest accident factor after carelessness. This is what inspired UNY students to design a driving safety pillow as an effort to minimize accidents caused by drowsiness. They are Suryadi (Automotive Engineering Education), Ikhwanudin (Electrical Engineering Education), Riani Fatimah (Clothing Engineering Education) and Aulia Avi Basuki (Accounting).
