A big change? Sometimes it just needs one small, brave step!
The Synchronize Fest 2025 music festival, held on October 3-5, 2025, at JIExpo Jakarta, was not just a place to enjoy music. It was also an action stage for climate change and energy transition. Joining the excitement with the spirit of Saling Silang, Enter Nusantara collaborated with Ruang Rupa to achieve two missions: teaching people about fun renewable energy solutions and pushing for a fair, systemic change.
How did Enter Nusantara do this?
Solar-Powered Ice Cream Machine and Daylight Monument

Who says renewable energy can’t be fun?
At the festival, Enter Nusantara had two cool installations that used 100% solar power. The Solar Ice Cream Machine was the main attraction. In the hot weather, Enter Nusantara gave out free ice cream made with a solar panel-powered machine. This was a fun way to show that clean energy is real, easy to get, and can be used every day.
In addition to the ice cream machine, there was also a solar-powered charging station inside the venue. Visitors could charge their phones with clean energy—a small but important step to support a sustainable lifestyle.
Besides that, Enter Nusantara also set up the Daylight Monument, an artistic installation that was also solar-powered.
More Than Just a Music Party, It’s a Climate Resistance Party

But Enter Nusantara’s part in Synchronize Fest was not only about fun and educational activities.
Because the earth’s temperature keeps rising due to the worsening climate crisis—which they felt clearly during the festival—Enter Nusantara went further. They turned the music stage into a resistance action stage.
Enter Nusantara used a small theatrical action amid the crowd to urge banks and the government to immediately end coal project funding and demonstrate a serious commitment to a just, inclusive, and community-based energy transition.
This action was based on the fact that a clean and fair energy transition risks becoming an empty promise. The government often delays renewable energy goals, while the banking sector still makes huge profits from dirty energy financing. Therefore, pressure from the public and collective awareness are the key to pushing for real, systemic change.
Synchronize Fest 2025 may be over, but the fight for clean energy, a fair transition, and against the climate crisis is not.
Enter Nusantara urges everyone, banks and government alike, to stop funding dirty energy, create solutions that truly help the people, and push for renewable energy that is fair for all, not just for a few big companies.
Let’s make sure that every small step we take, from choosing solar-powered ice cream to bravely speaking up for energy policy, becomes part of the big change we need.
