Led by General Manager Kunto B Wibisono, the Kupu-Kupu Malam team didn’t just aim to modify a car—they wanted to tell a story. According to Kunto, Hati Nurani is rooted in deep personal and cultural values. For them, modifying a car isn’t just about the aesthetics or performance specs; it's about putting soul into steel. And with this project, they’ve done exactly that.
The foundation of this extraordinary machine is a Chevrolet 51 sedan, with its original chassis preserved—though extensively stretched to support an additional axle. Drawing inspiration from nature, specifically the grasshopper (known locally in Javanese as Walang Kadung), the car features striking scissor doors that resemble insect wings in motion. This clever use of biomimicry gives Hati Nurani a uniquely organic yet futuristic character that sets it apart from anything else on the road.

Step inside, and the futuristic impression only deepens. The interior is fully customized with electric seats, a tailor-made gear lever, and uniquely engineered pedals. Every detail reflects thought and craftsmanship. Just in front of the gear shift lies a control panel with buttons for an advanced air suspension system—one for each of the six wheels, offering supreme comfort and control.

But perhaps the most jaw-dropping part of Hati Nurani is its sound system. It's not just powerful—it’s almost cinematic. Featuring a 2-DIN DVD system, five Venom monoblock amplifiers, three four-inch Venom amps, four 12-inch and six 10-inch Venom subwoofers, plus a combination of Venom split and coaxial speakers—this car doesn’t just drive, it performs. With 40 small monitors scattered inside and a pair of 7-inch screens, entertainment is everywhere. Add in the dual Venom capacitor banks and you’ve got a mobile concert hall that’s as technically impressive as it is immersive.

Building a car like this is no weekend project. It took the Kupu-Kupu Malam team around six months to bring Hati Nurani - Walang Kadung to life. While the exact cost has never been revealed, the result speaks volumes. The car claimed top honors as Champion at the prestigious Djarum Black Autoblackthrough in 2011 and continues to spark admiration and curiosity far beyond Indonesia.
