Sepatu baru itu membuat tumit saya lecet, jadi saya tidak memakainya ke kantor hari ini.

In Indonesian, the usual order is:

noun + adjective + demonstrative

So:

• sepatu = shoes
• baru = new
• itu = that/those, and often also the in context

That gives sepatu baru itu = those new shoes or the new shoes.

By contrast, itu sepatu baru usually means That is a new shoe / Those are new shoes, where itu is functioning as that at the start of a sentence, not as a modifier inside the noun phrase.

Here itu can be understood as a demonstrative, but in natural translation it often works like a definiteness marker.

So sepatu baru itu could be interpreted as:

• those new shoes
• the new shoes

In real usage, Indonesian itu often helps point to something known, specific, or already identifiable in the conversation, even when English would just use the.

Yes. Membuat literally means to make, but it is also commonly used to mean to cause.

So:

• membuat tumit saya lecet = made my heels sore/raw/blistered
• more literally: caused my heels to become lecet

This is a very normal structure in Indonesian:

X membuat Y + adjective/state

meaning X causes Y to become ...

Lecet refers to skin that has been rubbed, scraped, or chafed.

In this sentence, because the subject is shoes, a natural English translation would be something like:

• blistered
• rubbed raw
• chafed

There is not always one perfect English word-for-word match. The main idea is that the shoes caused minor friction damage to the skin on the heels.

Tumit saya literally means my heel or my heels.

A few important points:

• tumit = heel
• saya after the noun means my
• Indonesian often does not mark plural unless it really needs to

So tumit saya can refer to:

• one heel, or
• both heels

In this sentence, common sense tells us it probably means my heels.

This is very normal in Indonesian. English often forces you to choose singular or plural, but Indonesian often leaves that to context.

Because it is built from:

• memakai = to wear
• -nya = it / them

So:

memakainya = to wear it / them

The -nya here refers back to sepatu baru itu.

Since sepatu can mean shoe or shoes depending on context, memakainya can mean either:

• wear it
• wear them

In standard writing, this suffix attaches directly to the verb, so it becomes one word.

Pakai is the base form, and memakai is the verb with the meN- prefix.

Very roughly:

• pakai = wear/use
• memakai = to wear/use, in a more standard full verb form

In everyday speech, Indonesians often use pakai very freely:

• Saya tidak pakai sepatu itu.

In more standard or careful written Indonesian, memakai is often preferred:

• Saya tidak memakai sepatu itu.

So in this sentence, memakainya sounds natural and standard.

Because memakai is a verb.

In Indonesian:

• tidak negates verbs and adjectives
• bukan usually negates nouns, noun phrases, or equations/identifications

So:

• saya tidak memakainya = I do not wear it / I didn’t wear it
• bukan would not normally be used here

A simple rule of thumb:

• tidak
  • action/state
• bukan
  • identity/category

Here jadi means so, therefore, or as a result.

So:

• ..., jadi saya tidak memakainya ... = ..., so I didn’t wear them ...

It is true that jadi can also mean become in other contexts, but not here.

Compare:

• Dia jadi dokter. = He became a doctor.
• Hujan deras, jadi kami pulang. = It rained heavily, so we went home.

So the meaning depends on context.

Because ke shows movement toward a destination:

• ke kantor = to the office

By contrast:

• di kantor = at the office

In this sentence, the idea is I did not wear them to the office today, so ke is the natural choice.

Yes, it could go somewhere else. Indonesian word order is often fairly flexible with time expressions.

These are all possible, depending on emphasis:

• Saya tidak memakainya ke kantor hari ini.
• Hari ini saya tidak memakainya ke kantor.
• Saya hari ini tidak memakainya ke kantor.

Putting hari ini at the end is completely natural. It often sounds a bit like adding the time information after the main statement.

Indonesian verbs do not change form for tense the way English verbs do.

So memakai itself does not mean specifically:

• wear
• wore
• am wearing
• was wearing

The time reference comes from context and time expressions such as hari ini.

That means this sentence can be interpreted in English in different ways depending on context, for example:

• I’m not wearing them to the office today
• I didn’t wear them to the office today

English has to choose a tense, but Indonesian often leaves that to context unless extra markers are added, such as:

• sudah = already
• sedang = in progress
• akan = will

Sometimes yes, especially in casual conversation, if the subject is already obvious.

For example, you might hear something shorter like:

• ..., jadi tidak memakainya ke kantor hari ini.

But in standard, clear writing, repeating saya is very normal and often better:

• ..., jadi saya tidak memakainya ke kantor hari ini.

It avoids ambiguity and sounds complete.
