The Solar Shift: Empowering North Sumatra’s Aquaculture Through Innovation.

North Sumatra is home to some of the most breathtaking views in Indonesia, especially around the iconic Lake Toba. Here, the waters are alive with Floating Net Cages (KJA), where local farmers work tirelessly to provide fresh fish for the nation. But there’s a hidden struggle: most of these cages are far from the power grid.


Without electricity, modernizing a farm feels like an impossible dream. To bridge this gap, the Venambak team recently traveled to the heart of the region. Tongging Village (Karo) and Silalahi Village (Dairi) to introduce a game-changing solution: FEEDERVE PV.


The Power of the Sun, the Precision of Tech


Why FEEDER PV?


In the world of fish farming, feed is your biggest cost. If you waste feed, you waste money. But manual feeding in remote waters is hard to control. FEEDERVE PV solves this by combining a smart automatic feeder with its own solar panel. No cables, no loud generators, just pure energy from the sun.


5 Reasons Why FEEDERVE PV is a Game-Changer


During our trip, we showed local farmers how they could transform their daily operations using nothing but their smartphones and the sun:


  1. Zero Grid Required: It runs entirely on solar energy. This means you can automate your farm even in the middle of a lake where PLN cables can't reach.
  2. Control the Distance: Every cage is different. Through the Venambak app, farmers can adjust exactly how far the feed is thrown to make sure it reaches every fish.
  3. Feed with Precision: No more guessing. You can set the exact amount of feed released per second right from your phone.
  4. Track Your Data: Knowledge is power. The app records daily feed consumption, which you can download to see exactly how much you're spending and how your fish are growing.
  5. Monitor Your Energy: You can check your solar power levels in real-time, ensuring your equipment is always ready to go.


Learning from the Experts: The Farmers


Our visits to Desa Tongging and Desa Silalahi weren't just about showing off a new gadget. They were about listening.


We sat down with the local farmers to discuss their traditional methods and the challenges they face with floating cages. For us, their feedback is gold. The farmers shared their excitement but also challenged us to make the installation even easier and to keep the innovations coming.


This dialogue is what drives Venambak. We don’t just build tools; we build solutions with the people who use them every day.
