why are these named as "Sukorejo -speed unit-"?

Sebaiknya gunakan aplikasi SIG, bukan lewat Openstreetmap

I did search before commenting it. Another way to discuss it: https://community.openstreetmap.org/c/communities/id/58

"the suburb Gianyar is part of which town?"

Take a sample of a school:
way/326541185
SMPN 1 Gianyar address is in:
Jalan I Gusti Ngurah Rai, Kelurahan Gianyar, Kecamatan Gianyar, Kabupaten Gianyar.

You can discuss this matter to Indonesia Community about appropriate tagging for kelurahan (admin_level=7).

No, it's not. That is kecamatan. You can discuss further here: https://t.me/osmindonesia/13963

I think this the root of the duplicate; residential landuse. way/706551761

https://t.me/osmindonesia/13963

node/13716722641 is the Kecamatan Gianyar (town).

node/13716722819 is the Kelurahan Gianyar (not town, you were tagging this as town in changeset/191322937).

If you really want to discuss this further, you are most welcome to the OpenStreetMap Indonesia community under "Batas Administrasi" topic: https://web.telegram.org/a/#-1001185405807_13963

yang ditambahi ya harusnya hanya maxaxleload=*, bukan mengubah klasifikasi jalan

Menambahkan fitur bangunan, woilah

you can add specific access like: motorcar=no

You should consult with the community first, before adding administrative boundary.

Telah diperbaiki

Apakah bisa dikonfirmasi lagi nomor telepon 2031-232000? way/1382955218

what is the source of the ref=* tag?

Salam, saya sangat menyarankan Anda mencoba Tutorial Interaktif 10–15 menit di iD editor. Cukup klik tombol Edit/Sunting di web OSM, buka menu Bantuan (atau tekan H), lalu pilih Tutorial Interaktif untuk mempelajari cara membuat jalan, area, dan atribut (tag) dengan benar.

Tidak perlu ada "Gerbang Stadion...." di situ sudah ada lapangannya.
