Two students from the Master’s Program in Performing Arts and Visual Arts Studies (PSPSR) UGM, Febri Anugerah and Isradina Paricha, from the art collective Lelaku Studio, were participating artists in the Biennale Jatim XI, which took place from 20 August to 20 September 2025. The biennale, which is being held at the Pudak Gallery in Gresik, East Java, is themed Hantu Laut: The Spectre of The Sea and serves as a space to re-examine society’s relationship with the ocean. Lelaku Studio, active since 2018, is known for its distinctive artistic practice that merges archaeological research with material innovation. Their focus on repurposing High-Density Polyethylene (HDPE) plastic is not merely an aesthetic choice but also a principled stance aligned with sustainable production and environmental stewardship.
