Hello celbri, welcome to OpenStreetMap! It looks like you have already made some great edits. There is one issue, however, that I’d like to discuss with you. 

I noticed that you have been changing the classification of some highways to highway=service combined with a service=alley tag. For example this highway (https://www.openstreetmap.org/way/1183679456). Based on the Indonesia OSM Wiki page (https://wiki.openstreetmap.org/wiki/Indonesia), highways like this should be classified as highway=living_street since they are narrow residential ways that can be passed by 1 car at low speed. The presence of ‘Gang’ or ‘Gg’ in the highway’s name is also a good indicator of a living street. This highway can be seen in ground level imagery in Mapillary (https://www.mapillary.com/app/?lat=-7.99393245&lng=112.62033645&z=17&pKey=184906677331474&focus=photo&x=0.4026163394635524&y=0.4872437014876443&zoom=0).

Let me know what your thoughts are on this; happy mapping!
