Take a look at these two sentences.what is the difference is the meaning between them?
Lihat kalimat ini, apa yang berbeda arti dari kalimat ini?
I will explain to you what differecence is :
‘I cut my hair’ ( in this case i do it myself without helping from the people) .
‘i have myhaircut’ (in this case someone or hairdresser cuts my hair for me but i don’ t do it my self.)
We use have something done to mean another person does service .
Kita gunakan sesuatu yang sudah dilakukan yg berarti seseorang yg melakukannya.
The grammar for this is pretty simple:
Grammar seperti ini cukup sederhana
HAVE + OBJECT + PAST PARTICIPLE
The grammar is used in present by us. It’s difference with HAD + OBJECT+ PAST PARTICIPLE
it would use if the action happened in the past .
let’s take a look a few more examples:
lihat, beberapa contoh selanjutnya:
‘we didn’t want to cook so we had a pizza delivered’
It means we didn’t cook and someone delivered pizza for us . ( in this case probably deliverer) this action happens in the past.
‘I had my car washed at the new place by the station’
It means i didn’t wash car myself. Someone washed my car and did car service for me.( in this case probably washer man).
‘i got my watch fixed’ it means someone fixed my watch (in this case probably repairman).

FUTURE
As I mentioned before ‘I had my watch fixed’ tells us about the past
And for the future we use ‘Going to have/got + subject+ past participle’.
Take a look this example : ‘I am going to have/get my watch fixed’ tells us about the future.
It means I have a plan in the future that someone is going to fix my watch (it’s probably repairman).
‘Going to’ tells us about the future plan that has already been made .
‘going to’ menceritakan rencana dimasa depan yang sudah dibuat.
We use ‘will’ for something that has just been decided :
Kita menggunakan ‘will’ untuk sesuatu yang baru diputuskan
Okay I will give an example about ‘will’
‘I just noticed how dirty my suit is.I will have/ get it cleaned soon’.
It means my suit is dirty and i have just been decided to ask someone help to clean it or bring it to laundry .(it’s probably my maid, my mom or builders laundry)

QUESTION
Imagine that you like your friend’s haircut ; you could ask her :
Bayangkan bahwa kamu menyukai potongan rambut teman mu ; kamu dapat menanyakan teman permpuan mu :
‘where did you have/get your hair cut’
It means you asked your friend who cut her hair because you like her cut .
Maybe you have just moved to a new town and decidedthat it is time for haircut ; you can ask:
Mungkin kamu baru saja pindah ke kota yang baru dan memutuskan ini saatnya untuk potong rambut. Dan kamu dapat bertanya :
‘where can i have / get my haircut’
It means I ask people in the street because I just moved to a new town
Or ask to police in the police office where I can get a salon or beauty shop so hairdrasser in that shop can cut my hair or does service for me.
