Mapped areas are only the ones I have knowledge about and/or actually visited. Occasionally add interesting POI outside the place I visited.

Mainly Kota Malang and Kabupaten Malang.

Example of area I have fully or partially fixed:

• Taman Buah-Buahan Malang: building and its address number
  osm.org/#map=18/-7.974873/112.614664
• Sumber Kucur spring, Wagir: mapped with GPS and direct observation (unfinished)
  osm.org/#map=19/-7.980003/112.585552
• Yayasan Kolese Santo Yusup Malang and nearby area
  osm.org/#map=18/-7.938490/112.639201
• Perumahan Bandulan Permai
  osm.org/#map=19/-7.984877/112.604821

My priority:

• Farmland
• Forests
• Hospital and other healthcare system
• Libraries
• Parks
• Religious buildings
• Residential area (perumahan)
• River, stream, drain, and other water system

These wiki guidance for Indonesia seems not properly updated,
and even contradict with each other…

• osm.wiki/Indonesian_Tagging_Guidelines (the default search result on wiki)
• osm.wiki/Id:Pedoman_Penandaan_Indonesia (the one that linked on OSM ID Instagram)
