YOGYAKARTA – April 21, 2025 – Christian Ambrosius Diaz, a student in the Apothecary Professional Program at Universitas Gadjah Mada’s (UGM) Faculty of Pharmacy, has earned a significant international honor. He was awarded a Silver Medal at the Jakarta International Fair (JIF) 2025, a hybrid event held from April 14-17 in Jakarta. The competition, organized by the Indonesian Young Scientist Association (IYSA) and Indonesian Exalter Students, provides a stage for young innovators from around the world to showcase their creative projects.
Christian presented his innovation, titled Shelluminous: Innovation and Utilization of Kerang Dara (Anadara granosa) Shell Waste as a Body Scrub for Optimal Skin Beauty, in the Biotechnology and Health category. The project transforms blood clam (tegillarca granosa) shell waste, a common environmental issue, into a high-value cosmetic product. Shelluminous is formulated as a body scrub that leverages the high calcium carbonate content of the shells. Its natural abrasive qualities are effective at exfoliating dead skin cells and promoting skin regeneration.
Through extensive research, the Shelluminous formula was enhanced with other natural ingredients. Avocado extract was included to optimize the skin’s healing capabilities, while ginger extract, which is rich in curcumin, serves as a powerful antioxidant to protect the skin from free-radical damage. The result is a body scrub with a unique formula that is easy to apply, non-irritating, leaves no residue, and has an appealing appearance.
This achievement is not just a mark of academic excellence but also a direct contribution to several Sustainable Development Goals (SDGs). By applying circular economy principles—turning waste into a useful and economically valuable product—the Shelluminous innovation addresses the goals of responsible consumption and production (SDG 12). The initiative also aligns with the protection of life below water (SDG 14) by finding a use for shell waste that might otherwise pollute coastal areas. Furthermore, by creating a safe, natural, and accessible skincare product, the innovation supports the goal of good health and well-being for all (SDG 3).
“I am very grateful for this recognition,” Christian stated. “Shelluminous was born from a concern for the vast amount of seashell waste and its largely untapped potential. We wanted to prove that a material considered waste could be processed into a value-added product that is both safe and beneficial for skin health, while also offering a solution to an environmental problem.” He added, “I hope this can inspire other students, particularly here at UGM, to keep innovating and sharing their ideas with the global community.”
The team sees the silver medal as a stepping stone for future development. Their plans include conducting a series of clinical trials, including on animal subjects, to fully ensure the product’s safety and efficacy before it is made widely available to the public.
