Verify JVTO: Credentials, Police Authority & History

Don’t guess. Verify.

Audit JVTO's legal identity, historical continuity, and safety authority through our verifiable proof library.

Last reviewed 2026-08-06

JVTO publishes 12 official authority documents, 5 independent press references and 17 operational records, each anchored to a SHA-256 hash that is re-verified weekly. The legal entity is PT Java Volcano Rendezvous, NIB (Indonesian Business Identification Number) 1102230032918, with TDUP (Tourism Business Registration) issued 2023-02-11. Every claim here can be checked against an Indonesian government registry before you book.

What kinds of proof does JVTO publish before booking?

Four layers: (1) Legal — NIB/TDUP/AHU registration verifiable on Indonesian government registries; (2) Police — founder Bripka Agung Sambuko's SPRIN-POLPAR and SPRIN-WAL-TRAVEL assignment documents plus Detik.com identity confirmation; (3) Press & Recognition — the Stefan Loose editorial feature, the Booking.com 2015 award, and the Detik 2021 article; (4) History & Artifacts — operational continuity from the 2015 guesthouse era through the 2023 PT formalization.

Is Java Volcano Tour Operator a legal business in Indonesia?

Yes. JVTO operates under PT Java Volcano Rendezvous with Business Identification Number (NIB) 1102230032918 and a TDUP tourism licence under the same identifier (issued 2023-02-11). Both are searchable on the Indonesian government OSS (Online Single Submission) and AHU registries.

How can I verify the documents provided by JVTO?

Download the original file, compute its SHA-256 locally, and compare it to the published value to detect tampering. Where a registry link is provided, follow it to cross-check the details on the official government portal.

Why publish proof at all instead of just describing the tours?

Tour operators in Indonesia operate in a landscape where licensing claims are easy to make and hard to verify. JVTO publishes the actual government registry IDs and document scans so travellers can independently confirm every claim through third-party Indonesian data sources before paying any deposit.

What safety standards does JVTO follow for Ijen Crater tours?

Every climber undergoes a formal health screening, mandatory under BBKSDA SE.35/K2/BIDTEK.1/KSA/1/2024, with licensed physician Dr. Ahmad Irwandanu. HPWKI-certified guides lead all crater descents.
