Coal contributes 66%+ of Indonesia's electricity production, prompting Gusmantara Ekamukti Himawan to co-found Xurya Daya Indonesia. The company is dedicated to helping Indonesia's commercial and industrial sectors transition seamlessly to solar energy. Himawan, who serves as managing director, is developing a zero-investment business model that enables firms to make the switch without upfront costs. By making solar energy more accessible and financially viable, Xurya is reducing carbon footprints, contributing to a cleaner, more resilient energy future, supporting Indonesia's decarbonization goals, and shifting the country's mindset toward sustainability. Further, Himawan's contributions have positioned the company as a pioneer in business model innovation, IoT (Internet of Things)-enabled monitoring, and industry ecosystem development.

As of 2024, Xurya has opened up 100MW+ of operational solar capacity across 200+ projects, retained 100+ companies as clients, and built a 100% local workforce with more than 100 employees across four major cities. The company has generated 164 million kWh of clean energy annually, reducing 146,645 tons of CO emissions, which is equivalent to planting 1.97 million trees over 10 years. Also, Xurya has secured $88 million in funding and has achieved B Corp certification, reinforcing its commitment to high social and environmental standards. And, Xurya has been recognized by Forbes Asia's "100 to Watch 2023" and by G20 Digital Innovation Network as a top 2022 startup.

Himawan credits Purdue for his global mindset, adding that collaborative projects with international peers and access to a diverse network were invaluable in helping him navigate cross-cultural collaborations and expanding his perspectives.
