JVTO operates as PT Java Volcano Rendezvous, a registered Perseroan Terbatas (limited liability company) under the laws of the Republic of Indonesia. Every credential below is publicly verifiable through an Indonesian government registry — and the source documents are fingerprinted with SHA-256 hashes so they cannot be quietly altered.
Business registration
Three government records establish JVTO as a legal entity with a registered office, a tax identity, and a documented chain of responsibility — the things a roadside agent or a SIM-card WhatsApp number cannot produce.

Tourism & safety credentials
Holding a business license is the floor. Operating legally inside East Java's conservation areas — and putting credentialed guides on the trail — requires a further stack of authorizations.
| Credential | Identifier & function |
|---|---|
| HPWKI | AHU-0001072.AH.01.07.TAHUN 2024 Himpunan Pelaku Wisata Khusus Ijen — the state-recognized Ijen specialist guide association. Membership requires completion of BBKSDA-supervised volcanic safety training (SAR + emergency medical response). |
| BBKSDA clearance | Operator authorization to run trips inside Bromo Tengger Semeru National Park and the Ijen conservation area. Issued by BBKSDA Jawa Timur (bbksdajatim.org). |
| ISIC | Provider ID 259268 · UNESCO-endorsed. Official ISIC provider — student-pricing eligibility verified in real time via the Alive Verify API. |
| INDECON | Live member of the Indonesian Ecotourism Network — validates the community-based "Local Boys" employment policy. View listing. |
Medical credential
Because a health certificate is mandatory for every Ijen guest (BBKSDA SE.1658/KSA.9/2024), JVTO coordinates the clinic workflow with a named, licensed physician — not an in-house printout. The doctor behind every surat sehat is individually auditable.
| Officer | License & verification |

| Dr. Ahmad Irwandanu | Licensed Medical Doctor (Dokter Umum), SIP-credentialed. Registered with Kemenkes RI · SatuSehat SDMK · KKI. STR · satusehat.kemkes.go.id KKI · kki.go.id/cekdokter |
Forensic integrity — SHA-256 anchors
The source document for each credential is published with a SHA-256 hash in public/llms.txt on our website. A SHA-256 hash is a cryptographic fingerprint: if a single character of a document changes, the hash changes completely. You can compute the hash of any document we send you and confirm it matches — proof the file has not been altered, without us having to release the original.

Why these are costly signals
A credential is trustworthy in proportion to how expensive it is to fake. Each item above is a barrier to entry that an illegitimate operator cannot clear:
- NIB & TDUP require a physical headquarters, tax compliance, and legal liability — ongoing commitments a ghost operator cannot sustain.
- HPWKI membership requires government-supervised BBKSDA training. It cannot be purchased or self-issued.
- SHA-256 hashes make every document tamper-evident — alteration is mathematically detectable.
These are not marketing badges. They are the things that are hard to obtain and impossible to forge.
Address continuity
JVTO has operated from the same Bondowoso address since before the company existed. Our office sits at Jl. Khairil Anwar No.102 A, Badean, Bondowoso, Jawa Timur 68214 — the same address where the predecessor "Ijen Bondowoso Homestay" received its Booking.com Guest Review Award (9.4/10) in 2015. The award shipping label, addressed to "Agung, Jl. Khairil Anwar No.102, Bondowoso," documents an unbroken operational presence from the guesthouse era through PT incorporation to today.

Scans of the Akta Pendirian (Articles of Incorporation), the Kemenkumham (AHU) approval letter, the NIB certificate, and the TDUP can be requested directly via WhatsApp before booking — each matched to the SHA-256 hash above.
