Hidden Entities

Martinus Dwi Marianto (born in Jakarta in 1956) conceptualises art and reality through a holistic ecological paradigm. Central to his philosophical approach is the idea that all phenomena are intrinsically interconnected, existing within the ontological dualities of mind and body, as well as form and void, in a state of perpetual becoming. Within this framework, trees function as cosmic antennae, connecting human perception with the natural environment. Ecological degradation is therefore not merely an external environmental crisis but also a profound existential concern that affects human consciousness.
Driven by this ecological ethos, Marianto established the EcoArt curriculum at the Institut Seni Indonesia (ISI) Yogyakarta in 2015. Developed in response to escalating deforestation and illegal mining, the initiative positioned artistic expression as a critical medium for environmental critique and intervention. Over time, the programme expanded beyond the institution, fostering interdisciplinary dialogue and collaborations at national and international levels.
In recent years, Prof. Marianto's academic and activist work has focused on Pangium edule, locally known as the Pucung tree, a culturally and ecologically significant native species threatened with extinction. Through artistic practice, academic publications and community engagement, he advocates for the conservation of vulnerable plant species and local biodiversity. His efforts also led to the Adopt-a-Parent initiative, a community-based conservation model promoting the distribution and cultivation of Pucung seeds and other native species to help restore degraded ecosystems.

Septian Pujiandriyanto, M.Sn., is a sculptor, academic and manager of Sarana Karya Studio, based in Magelang, Central Java. Born in Magelang on 2 September 1986, he completed his higher education at the Indonesian Institute of the Arts (ISI) Yogyakarta. He earned a bachelor's degree in fine arts, specialising in sculpture (2007–2014), followed by a master's degree in fine arts creation and research (2014–2016). His practice combines theoretical knowledge and practical experience in the spirituality and aesthetics of the Indonesian archipelago (Nusantara), with a particular focus on Javanese spirituality in sculpture, as explored in his postgraduate project. Since 2023, he has also taught in the Sculpture Department at ISI Yogyakarta.
Pujiandriyanto has managed Sarana Karya Studio since 2008, developing a substantial body of work that includes monumental sculptures installed at temples, in public spaces and in private collections in Indonesia and abroad. His practice encompasses statues, reliefs, miniature temples and large-scale architectural elements featuring Buddhist ornamentation. He primarily works with natural stone, including andesite, river stone, limestone and green granite.
His projects include the Lumbung Miniature Temple, which serves as a columbarium for the late Soegiharto Sosrodjojo, founder of Teh Botol Sosro, at Slawi Vihara; a relief commemorating the 50th anniversary of Mendut Vihara; representations of Buddhapada (the Buddha's footprints); a 3.8-metre Buddha Rupang statue in Bangka Belitung; and statues of Sariputta and Mogallana.
Beyond stone, his work extends to bronze, brass, aluminium, fibreglass, cement and clay. These materials are used to create sculptures for commercial and spiritual projects, public monuments and decorative lamp covers featuring the mythical figures Kinara and Kinari.
Alongside his commissioned work, Pujiandriyanto remains actively involved in the national and international art scene through exhibitions and cultural events. Recent presentations include YICAF #3 (2025), held at the Faculty of Visual Art and Design at ISI Yogyakarta, and Hello There Postcard Reconstruction (2024). In 2022, he worked as an assistant on art installations for the G20 Cultural Carnival in Borobudur. His exhibition history also includes Tilik Konco, Jejak Peradaban Kartini, Biennale-Gerimis #4 and Tropis at Bentara Budaya Yogyakarta. Located in Dusun Tangkilan, Pabelan, Mungkid, Magelang, Sarana Karya Studio brings together cultural traditions, spirituality and contemporary sculptural practice.

Nico Schleicher (born in Vienna in 2001) is a multidisciplinary artist working across drawing, writing, installation and time-based media. His practice often begins outdoors, in nature, where he documents his observations through long-distance hikes and field research. 
With a background in architecture and spatial planning, alongside ongoing studies in social sciences and cultural studies, Schleicher combines artistic exploration with sociological inquiry.
His work examines the political and social implications of landscapes, exploring how humans transform their surroundings and leave physical traces. Through analytical and experimental engagement with his immediate environment, he investigates questions of presence, absence and transience, developing a language that is both personal and poetic, yet also political.
For Schleicher, drawing and writing serve as physical translations of emotion and systemic observation. Through open-ended processes, materials shift and transform, leaving behind tangible, sensory traces of time and movement. These traces may also be understood as echoes: impressions of another place and another time.
