Bali

Live preview available. A Stage-2 mockup of the Banjar Serangan hyperlocal dashboard — the first instantiation of the matryoshka IA decisions for this pilot — is open for partner review. View the Serangan Hyperlocal Dashboard preview →. Specific feedback asks (trust-ring UX, tier-label localization, Indonesian translation, sensor-integration cadence) are listed on the preview page.

Bali is one of the four bioregional pilots in PLANETAI, alongside Barcelona, Boston, and Santiago de Chile. Within the program's pilot stratification it is currently classified P2 — meaning it has lower instrumented sensor density than the European/American pilots at start, but a notably stronger sovereign-data foundation and a coalition-grade institutional partnership infrastructure to plug into.

The pilot is designed to mirror the governance pattern that the Green Hydrogen Village (Serangan) project has already validated in practice: CAST Foundation coordinates and administers, MDG / Fab Lab Bali executes, and IT Del's Bali office (led by Ben Koo) runs the technical AI and data layer, with IT Del's Sumatra campus providing national-scale compute backbone. All three are members of the Bali Net Zero Emission Coalition (with Azura Indonesia, IESR, NEN Indonesia, and WRI Indonesia as secretariat).

The pilot's most distinctive methodological commitment is the Tri Hita Karana ↔ four-pillar mapping, scoped explicitly as a Bali co-design experiment (per the Path B decision). Publication of this mapping is conditional on customary-authority sign-off — banjar adat, desa adat, or a PHDI scholar — to be named jointly by the Bali partner team.

Bali Satu Data — the Bali Province open-data portal under Governor Regulation (Pergub) 53/2021, published by Tim SPBE Diskominfos. The portal carries 4,700+ datasets organised through six Tri Hita Karana cosmological categories: Jana (society / people), Atma (wellbeing / spirit), Jagat (territory / world), Wana (forest), Danu (water), Segara (sea / coast). Release cadence is broadly annual — meaning sub-annual measurement requires sensor-campaign supplementation. (balisatudata.baliprov.go.id)

Bali Net Zero Coalition MEL framework. Already in operation, with WRI Indonesia behind it and dedicated MEL hires landing in 2026. The intent is for PLANETAI Bali to plug into this framework rather than duplicate it.

Indonesia NSDI (national geospatial data infrastructure) via BIG, plus decade-scale ERA5 climate analyses for Lake Toba (Nature Sci. Reports 2023) and World Bank water-quality remote-sensing work for the same region — directly relevant to IT Del's compute-backbone story.

Tropical-humidity sensor calibration. Existing literature provides ML calibration models with humidity + particle-count predictors — see for example the Bandung PurpleAir study (2022–2023, ScienceDirect). PLANETAI Bali applies the existing methodology rather than redoing the underlying research.

Fab Lab Activity Index (Boeing 2024). Used at Community-tier as a DIDO-side capacity signal — per-capita fab-lab + Fab Academy + Precious Plastic activity density. This complements rather than substitutes for ECI; Metroverse does not currently cover Denpasar.

These are the questions where partner input is most welcome — naming, coverage checks, capacity confirmations.

• Customary authority for Tri Hita Karana Path B. Per the network-level Path B decision, publication of the Tri Hita Karana ↔ four-pillar mapping is conditional on customary-authority sign-off. The named authority (banjar adat, desa adat, or PHDI scholar) has not yet been jointly proposed by CAST + MDG + IT Del. This is the single highest-priority naming.
• WRI Indonesia named MEL counterpart. WRI is secretariat for the Net Zero Coalition and is hiring a Bali-based Net Zero Emission Policy Specialist for 2026. PLANETAI Bali would benefit from a named individual counterpart relationship with WRI, not just a coalition-level one.
• IT Del Bali office capacity made legible to partners. Ben Koo's team in Bali, the Sumatra AI compute backbone, and PKC's relevance to PLANETAI's federated-architecture spec are all real but currently undocumented at partner-facing detail. A short capacity note (one to two pages) from Ben would close that gap.
• CAST role beyond Hydrogen Village. The Hydrogen Village pattern has CAST coordinating one workstream. PLANETAI Bali would extend that across multiple workstreams (sensors, data, governance, hub operations). Worth an explicit CAST confirmation that the broader coordinator role is welcome and resourceable.
• Bali Satu Data sub-annual cadence. Which specific datasets are published more frequently than annually, at what cadence, and against which Tri Hita Karana category? This determines what sensor-campaign supplementation is actually required for H₀-T (the program's pre-registered material-throughput hypothesis).
• Fab Lab Activity Index density at Denpasar neighbourhood scale. Is per-capita FLAI rich enough to anchor a Community-tier signal in Denpasar specifically, or does sample density require supplementing through fablabs.io activity logs and Fab Academy alumni density?

Drafted from the working-notes brief; partner pushback on any of these is the point of this page.

The Bali pilot is anchored on three coherent data sources: Bali Satu Data as the sovereign primary, the WIPO Global Innovation Index 2025 (Indonesia 55/139, 8th of 36 upper-middle-income, 12th of 17 in SEAO) as a country-level Bioregion-tier peer anchor, and the Fab Lab Activity Index as the Community-tier DIDO-side capacity signal. This is the framing locked in the Bali three-source decision.

Governance mirrors the Green Hydrogen Village pattern: CAST coordinates / administers, MDG & Fab Lab Bali execute, IT Del's Bali office runs the technical AI and data layer with the Sumatra campus as compute backbone. The customary-authority partner is named jointly during pilot setup and gates the Tri Hita Karana mapping publication.

The data flow is bilingual by design: data ingested at the Bali bioregion server (IT Del) in its native Tri Hita Karana taxonomy with Indonesian metadata preserved verbatim; mapping to the four-pillar framework applied only at the cross-pilot federation layer; cross-pilot results re-rendered through Tri Hita Karana before delivery to Balinese municipal liaisons. This is the operational form of CARE-aligned sovereignty-by-architecture at the data-taxonomy layer.

Partnership ambitions extend the Bali Net Zero 2045 Coalition's existing MEL framework with sensor campaigns, federated SLM instantiation, and the matryoshka hyperlocal dashboard prototype (see the Stage 1 IA decision, with Bali as the anchor pilot for Stage 2 mockups — a live preview is available for the Banjar Serangan instance).

The pilot's success is not "Bali matches Barcelona's instrumentation density." It is "Bali demonstrates that sovereign provincial data + cosmological taxonomy + customary-authority partnership produces a measurement substrate as scientifically valid — and methodologically distinct — as the European pilot's." That distinctness is the Bali contribution, not a fallback.
