SMAN 9 Yogyakarta conducts a two-days social working activity on 10 to 11 April 2023 at the Museum of Biology UGM. This activity involves five students of class XI MIPA 6. They are Alexandra Elana Katja Nindiadhi, Azra Zahida Aryawijayanti, Madah Sulam Cahya, Mutia Afinda Fadilah, and Sekar Ayu Fahriyah. On the first day, Ida Suryani as the museum staff provides the students with a brief description about museum collections and conservation materials. Next, students help to clean the collections of preserved dried plants such as sea pandanus fruit, siwalan fruit, rattan herbarium and many more. On the following day, students help to clean the collection displays on the cupboards and shelves in 10 showrooms. It is hoped that social working programs can provide the students with experience and enhancement of knowledge about biology. In the future, more collaborations between the museum and other schools to conduct social working program activities are welcomed.
