I. Prologue – Story Behind the Project
Over the past few years, the principal of Studio Hendro Hadinata; Hendro Hadinata, has traveled to several regions in Indonesia to explore local emerging identities and cultural heritage. This journey began with Hendro’s belief that the future of design is rooted in traditional culture.
Personally engaging in meaningful conversations with local crafters, Hendro has gained insightful stories and identified design opportunities. This approach has enabled our studio to be grounded in the unique localities of Indonesia.

In 2023, we were chosen to be one of the designer collaborators for “CULTUKAR – Years of Culture,” an international cultural event initiated by Qatar Museum (M7).
The event was envisioned to collect a deeper understanding between the two countries on culture, environment, habit, and design topics. Together with Noora Al-Melhim, a product designer from Qatar, we explored one of the overlooked regions, yet full of golden heritage, Sumba. The exact location is Waingapu, located in the heart of East Sumba; which is more indigenous than other areas on the same island.
During our journey, we uncovered a fascinating revelation: East Sumba was once submerged beneath the ocean, leaving behind remnants of coral atop the land. Thus, every step taken on East Sumba’s terrain today is a walk through its oceanic past, a proof to its enduring history and remarkable transformation.


II. About Mamuli
Beyond the picturesque coastal views and stunning landscapes, the true treasure of East Sumba lies in its craftsmanship.
From one home to another, locals engage in the art of crafting as a means of livelihood. These crafts represent a longstanding tradition of handcrafted metal jewelry production. Originally, this craft was employed in the creation of ‘Mamuli’—jewelry from a groom and his bride as a symbol of their committed relationship.

Mamuli comes in a variety of sizes, all crafted with the same technique usually from 1 cm until 40 cm in diameter. It makes them used to make details in small scale products. Started with a ply of metal sheets, they apply heat to soften them, rendering them pliable for manipulation. Skillfully bending and shaping the metal, they meticulously carve out and style the distinctive three-dimensional oval form, showcasing the artistry craftsmanship in Mamuli default creation.
The local artisans have extensive knowledge of the materials they work with, allowing them to optimize their techniques during the manufacturing process (heating, folding, and forging).
These deep explorations lead our studio to collaborate with local crafters from Sumba to create a series of products made with metal sheets.
We aim not only to explore shapes but also to consider how we can make them unique and extraordinary. After learning extensively from the locals, Hendro conceived the idea of using embossing, debossing, and stamping techniques. The thin and malleable characteristics of the material enable us to achieve tactile effects. The outcome resulted in the formation of a three-dimensional pattern that is both visible and tangible.
