Damage to roads with concrete pavement is often found in rural areas, one of the causes is the use of roads that exceed the maximum load of the road. This is due to inappropriate material selection or imperfect construction methods in implementation. Therefore, it is necessary to develop in the field of construction, especially road pavements that use concrete with the addition of mixtures from environmentally friendly materials.

Telang flowers can grow as ornamental or wild plants with single blue-purple petals. Apart from being an ornamental plant, telang flowers have been traditionally known as an eye medicine and purplish-blue food coloring. This plant has different names in each region in Indonesia, such as in Sumatra called lentil flower, in Java called teleng flower, in Sulawesi called talang, and in Maluku called bisi flower. Telang flower is the most popular edible flower at the moment. Telang flowers are famous for being dried before being consumed as a tea.

A group of UNY students has achieved several achievements through a technology startup business called SineasHub.

The existence of transportation is a vital need for the community. The importance of transport cannot be separated from the mobility needs that the community must carry out. The increasing number of motorized vehicles sees this transportation need to this day. This increase in the number of vehicles must be accompanied by providing road infrastructure that supports safe driving. One of the enabling factors in driving safety is the provision of facilities or infrastructure for safe driving behaviour, such as traffic signs and street lighting.

Sorghum is one of the cereal products that are widely grown in Indonesia. This type of cereal has a higher vitamin and mineral content than wheat, and even sorghum has a high antioxidant substance. Consuming sorghum can prevent diabetes. Although sorghum's benefits are abundant, its utilization is minimal, and it even ends up as animal feed. This fact attracted the attention of UNY students, who mixed it into sorghum compote cake. She is Tika Nur Affrimawati.

A team of UNY students consisting of Yustina Rahma Sari, Linda Oktafianingsih, Brina Gamelisa, Kiki Adisti, Rahayu, Tiar Rahmasanti, Arief Kurniawan, Fani Maulana, Muhammad Raihan A and Tria Adelia succeeded in processing banana stems into chips. "After harvesting bananas, banana tree trunks are cut down and rotted. People mostly have not used banana stems, so the stems have no economic value. Therefore, we are interested in making food innovations from banana stems," said Yustina Rahma Sari.

Cassava is one of the foods that are widely consumed by Indonesian. Almost all parts of cassava can be utilized, cassava leaves can be processed into vegetables, cassava tubers are also widely consumed and have great potential for raw materials for flour processing because they contain a lot of starch. Apart from the utilization of cassava for flour processing, there are still many other benefits in the form of cassava, mocaf flour, and processed cassava into snacks.

Corn (Zea Mays L) is a plantation crop that thrives in Indonesia and can be harvested 2-3 times a year. The corn harvest period is the most awaited because farmers benefit from their crops. However, most of the corn is sold a whole. The corn cobs are only burned and even thrown away as waste. The problem is that corncob waste is easily decomposed and causes an unpleasant odor. This problem has prompted Ade Kurniawan, a student of craft education at UNY, to process corncob waste into handicraft products that are sustainable, eco-friendly, and encourage zero waste implementation.

Indonesia is ranked in the top 3 as the largest fish-producing country in the world, after China and India. However, the Balitbang of the Ministry of Maritime Affairs and Fisheries explained that per capita fish consumption in Indonesia has only reached 25.77 kg. This figure is relatively low when compared to other countries, where one of the causes of the low consumption of fish is the price which is still relatively high. This high price is due to the lack of efficient technology and methods of freshwater fish farming currently used.

The covid-19 pandemic has forced us to adopt a new normal. One of the new normals is the implementation of physical distancing. Everyone must keep their distance to avoid transmission of the covid-19 virus from droplets that come out when coughing, sneezing, even when breathing and talking. Therefore, everyone should ideally maintain a distance of at least 1 meter when interacting with other people. To make physical distancing more effective, the UNY student team designed a Raspberry Pi-based warning tool for physical distancing violations to prevent the spread of COVID-19.
