Q & A

What makes Desa Karangtengah unique compared to other villages in Indonesia?

Desa Karangtengah is unique because it is a self-sustaining energy village powered by a Micro-hydro Power Plant (PLTMH), unlike other villages in Indonesia that rely on electricity from PLN, which is often sourced from coal-powered plants.

How did the electricity situation in Desa Karangtengah change over time?

Previously, the villagers lived without electricity and used traditional oil lamps at night. However, after the installation of the PLTMH in 2012, they gained a stable and reliable source of electricity from the river's current.

Who was involved in the development of the Micro-hydro Power Plant in Desa Karangtengah?

The Micro-hydro Power Plant was developed with the assistance of the Indonesian military (TNI) in 2012 and was later taken over in 2015 by the Provincial Government of Central Java and the Department of Energy and Mineral Resources.

What are some of the challenges faced by the village regarding the PLTMH?

Some of the challenges include land ownership issues, where the village must pay annual rent for land used by the turbines, and the potential risk of the landowner discontinuing the lease. Additionally, natural obstacles such as flooding, debris, and strong winds affect the power plant's operation.

How do the villagers maintain the Micro-hydro Power Plant?

The villagers perform regular maintenance on the PLTMH every two weeks, including cleaning the water intake and ensuring the turbines are free of debris to maintain its functionality.

What impact has the PLTMH had on the villagers' electricity costs?

The PLTMH has reduced electricity costs for the villagers. They pay around 25% less than the standard rates charged by PLN, with household electricity bills ranging from Rp15,000 to Rp50,000 per month, which is half the cost of PLN electricity.

How has the introduction of the PLTMH affected the local economy?

The introduction of the PLTMH has stimulated the local economy by enabling businesses to operate more efficiently with a reliable power supply. This has led to the opening of small shops (warungs) and better access to the internet, enhancing economic activities.

What social benefits have resulted from the Micro-hydro Power Plant?

The PLTMH has helped strengthen social bonds within the community. Villagers cooperate in maintaining the power plant, and if one household experiences power outages, others step in to help resolve the issue quickly.

What role does tourism play in the future of Desa Karangtengah?

Desa Karangtengah is exploring eco-tourism as a potential revenue stream. They hope to attract visitors interested in learning about renewable energy and the future of clean energy, turning the village into an educational hub.

Can the model of Desa Karangtengah be replicated in other parts of Indonesia?
