TRENGGALEK – Longkangan tradition intangible cultural heritage status has been officially granted by the Indonesian government, recognizing a 176-year-old coastal ritual that local communities have preserved across generations.

Trenggalek Cultural officer Heru Dwi Susanto from the regional Tourism and Culture Office said the designation acknowledges a living tradition that continues to shape community identity despite lacking physical form.

“This recognition is part of government protection efforts by formally listing community practices as heritage,” he said.

Officials confirmed that the Longkangan ritual meets national criteria for intangible cultural heritage. The tradition has been practiced continuously for 176 years, far exceeding the minimum 50-year threshold required for recognition.

“Longkangan has existed for about 176 years and continues without interruption. That is several times beyond the minimum eligibility,” Heru said.

Authorities began the nomination process in late 2024. Provincial cultural experts first reviewed and curated the submission before forwarding it to the national level under the Culture Ministry.

After verification, an expert panel recommended Longkangan to the minister for designation as intangible cultural heritage. The ministry then issued an official certificate.

The minister presented the certificate to the provincial governor, who later handed it to the Trenggalek regent, completing the formal recognition process.

Officials say the designation strengthens protection for the Longkangan tradition intangible cultural heritage and supports its preservation among coastal communities.
