REPUBLIKA.CO.ID, JAKARTA -- Minister of Energy and Mineral Resources Ignasius Jonan has inaugurated the Lake Toba Caldera Information Center in Parapat, Girsang Sipangan Bolon Sub-district, Simalungun District, North Sumatra Province.

In statement received by Antara here on Friday the minister hoped that the national geo-center could be developed to be an international-standard geo-center.

"Let us help and support the District Administration to operate this geo-center. It is one of the largest geoparks located on a mountain in the world, even in Europe I do not see this big geo-center. The challenge is how to make it a tourist destination," Jonan said.

Dannish tourists visit Lake Toba.

In addition to the Information Center, infrastructure is also a concern of the administration. "Railway infrastructure from Medan to Siantar will be repaired so that the three hours trip can be juts an hour," he added.
