Yohanes Mario Putra Bagus as the Head Developer of Ferrumium said that the creation of Ferrumium also stems from his love for mecha series, such as Gundam and Transformers. On the other hand, he is also concerned about the suboptimal waste management in the country. It is from this concern that they innovatively transform waste such as gas lighters, plastic bottles, and wood into aesthetic and economically valuable action figures.

The use of selected wayang characters aims to promote local wisdom in the form of wayang stories that are currently less favored by the community. According to them, each character has its own uniqueness based on the story in wayang. "With the Augmented Reality feature, buyers can enjoy 3D modeling through the Ferrumium application," added Bintang.

The following is the translation of the given 'Bahasa' text to 'English' while preserving any html tags: "Bintang said that although made from used materials, Ferrumium does not have a worn-out or ordinary appearance. Ferrumium is made in such a way that it pays attention to the details and aesthetics of an action figure, resulting in a manifestation of art with a very attractive visual appearance. "Our action figures are designed with a height of 30 cm and a width of 10-15 cm, and they have a sturdy structure so they can be played with just like an action figure," said Bintang."

Ferrumium is also present as an educational tool, as the naming of the characters is based on the stories of wayang characters. In this way, Ferrumium becomes a medium for the introduction and preservation of national culture so that it is not eroded by the rapid development of time. "We market Ferrumium in a set that includes 1 Ferrumim, 1 stand, 3 stickers, and 1 application account. For one package, we sell it for Rp300,000," said Stephanie. This product is marketed through social media IG: @pkmugm_ferrumium and FB: pkmugm_ferrumium market place. In addition to this, the product is also available on Amazon and Shopee marketplaces.
