Metodologi

Setiap lapisan di Mandum Rimba memiliki sumber, tanggal pengambilan, dan metodologi. Halaman ini menjelaskan dari mana data berasal, bagaimana diolah, serta batasannya.

Batasan

Peringatan satelit memiliki false positive; resolusi piksel 10–30 m; batas konsesi publik bisa kedaluwarsa; agregasi DAS adalah pendekatan berbasis wilayah administratif yang beririsan. Versi metodologi dicatat pada setiap rekaman turunan dan setiap perubahan dicatat di changelog ini.

Catatan hukum

Mandum Rimba menghimpun data publik pihak ketiga dan menampilkannya apa adanya; kami tidak menyimpulkan, tidak menuduh, dan tidak menyatakan bahwa pihak mana pun melanggar hukum. Nama perusahaan, konsesi, dan lokasi berasal langsung dari dataset sumbernya, bukan dari kami. Irisan antar-lapisan adalah konteks, bukan vonis, dan kehilangan tutupan pohon tidak selalu berarti deforestasi ilegal. Kami menghormati asas praduga tak bersalah, dan terbuka atas permintaan koreksi untuk kami tinjau dan perbaiki.

Changelog metodologi

• 2026.07.2, Added a Tree cover loss layer to the main map (/peta): the Hansen/UMD annual tree cover loss raster (>30% canopy) streamed live from Global Forest Watch's encoded tiles, decoded per-pixel in the browser and coloured by loss density (amber → deep red), with a 2001–2025 timeline you can scrub or play to watch loss accumulate. It replaces an earlier province-level loss choropleth. Tree cover loss is not always deforestation, so the layer is presented as loss, not as a deforestation verdict.
• 2026.07.1, Two coastal & wetland habitat layers added to the main map (/peta): Mangroves (Global Mangrove Watch v3, ~223.900 polygons, 2020 extent) and Peatlands (Global Forest Watch 'Indonesia peat lands'). Both are carbon-rich, fire-prone ecosystems and critical wildlife habitat. Default-visible layers were retuned so the map opens on the human-pressure vs. protection story: concessions, protected & moratorium areas, mangroves, and peatlands are on by default; the Wildlife Distribution layer is now off by default (opt-in) to reduce initial clutter.
• 2026.07.0, Biodiversity map (/biodiversitas) reworked: the endemic-fauna and iconic-flora layers changed from scattered occurrence dots into DISTRIBUTION AREAS — curated GBIF points contoured per island into smooth density areas (fauna coloured by Sundaland/Wallacea/Papua biogeographic zone), the same organic-contour treatment as the Wildlife Distribution layer. The 'Biodiversity record density (GBIF)' raster overlay was removed as unhelpful noise. Two orphaned tilesets (wildlife habitat + occurrence points) that no map layer used were retired from the pipeline and object store.
• 2026.06.2, Wildlife layer reworked from occurrence points into a habitat-aware Wildlife Distribution layer: GBIF occurrences of threatened + flagship/endemic species (all classes, hundreds of species) are weighted by ESA WorldCover natural-habitat cover, city points are dropped, then density is contoured per island so each species stays on its actual island (a Sumatran tiger never bleeds into Java). Cryptic species whose coordinates are withheld for protection (e.g. Sumatran rhino) are added as clearly-flagged documented-range markers (IUCN/KLHK), not field records. The standalone RESOLVE ecoregion habitat layer was retired; its role is folded into the distribution layer's habitat weighting.
• 2026.06.1, Wildlife coverage expanded from 10 to 30 flagship species, every biogeographic region (Sundaland, Wallacea, Papua) and ecosystem (land, sea, freshwater), not just western Indonesia. Species now selected from Indonesia's protected-species law (Permen LHK P.106/2018), KKP marine rules & CITES, with IUCN Red List status and GBIF occurrences (filtered to 1990–present, removing stale museum specimens). Every occurrence coordinate is validated against an Indonesia land mask (Natural Earth 1:50m) and the species' realm, so marine animals mis-plotted inland (or land animals offshore) are dropped as gross coordinate errors, legitimate coastal records are kept. The layer was renamed from 'threatened' to 'protected' wildlife to match.
• 2026.06.0, Initial data pipeline: ingest and publish deforestation alerts, concessions, protected & moratorium areas, disasters, wildlife habitat and occurrences.
