Pada awal bulan ini, kami memperbarui anggaran keluarga di aplikasi sederhana.

In Indonesian, demonstratives like ini and itu usually come after the noun they modify.

• bulan ini = this month
• aplikasi ini = this application
• keluarga itu = that family

So Indonesian uses noun + ini/itu, not this + noun like English.

In the sentence, awal bulan ini means the beginning of this month.

Pada is a preposition often used before time expressions, especially in slightly more formal or careful writing.

• Pada awal bulan ini = At the beginning of this month
• Pada hari Senin = On Monday

In everyday Indonesian, people sometimes omit it if the meaning is already clear:

• Awal bulan ini, kami memperbarui...

So pada is natural and correct here, but not always strictly required in casual speech.

The comma separates the time phrase from the main clause.

• Pada awal bulan ini, = a time-setting phrase
• kami memperbarui anggaran keluarga... = the main statement

This is similar to English:

• At the beginning of this month, we updated the family budget...

The comma is especially common when a longer adverbial phrase comes at the beginning of the sentence.

This is a very common learner question.

Indonesian has two different words for we:

• kami = we, but not including the person being spoken to
• kita = we, including the person being spoken to

So in this sentence, kami means the speaker and someone else updated the family budget, but the listener is not part of that group.

If the speaker were including the listener, they would use kita instead.

Memperbarui means to renew, to update, or to make new again, depending on context. Here it means to update.

It comes from baru, meaning new.

Very roughly:

• baru = new
• memperbarui = to make something new again / to update

So kami memperbarui anggaran keluarga means we updated the family budget.

This is a verb with affixes, which is very common in Indonesian. Learners do not always need to analyze every affix deeply at first, but it helps to know that many Indonesian verbs are built this way.

Yes, memperbarui is the standard modern form.

You may also encounter memperbaharui, and many native speakers use it, but memperbarui is generally preferred in standard Indonesian.

So for learning and formal writing, memperbarui is the safer choice.

In Indonesian noun phrases, the main noun usually comes first, and the word after it describes or limits it.

So:

• anggaran = budget
• keluarga = family
• anggaran keluarga = family budget

This pattern is the reverse of English in many cases.

Compare:

• rumah sakit = hospital
• buku sejarah = history book
• anggaran keluarga = family budget

The head noun here is anggaran, and keluarga tells you what kind of budget it is.

It means in a simple application or in a simple app.

Breakdown:

• di = in / at / on
• aplikasi = application / app
• sederhana = simple

So the phrase tells you where they updated the family budget: they did it in a simple app.

Because this di is a preposition, not a verb prefix.

• di aplikasi = in the application
• di rumah = at home
• di kantor = at the office

Prepositional di is written separately from the following word.

But there is also a different di-, which is a passive verb prefix, and that is written together:

• ditulis = written
• dibuka = opened

So:

• di aplikasi = correct, because it is a location phrase
• diaplikasi = wrong in this sentence

It describes aplikasi.

So:

• aplikasi sederhana = simple application

The phrase structure is:

• di aplikasi sederhana
• in a simple app

It does not mean the budget is simple. If you wanted to say a simple family budget, you would say something like anggaran keluarga sederhana.

The sentence is natural as written, but Indonesian word order has some flexibility, especially for time and place phrases.

The original sentence:

• Pada awal bulan ini, kami memperbarui anggaran keluarga di aplikasi sederhana.

You could also say:

• Kami memperbarui anggaran keluarga di aplikasi sederhana pada awal bulan ini.

Both are grammatical. The difference is mostly one of emphasis and style:

• Putting Pada awal bulan ini first emphasizes the time
• Putting it later makes the sentence start more directly with the subject and action

Sometimes yes, if the context already makes the subject clear.

For example, in conversation, someone might say simply:

• Pada awal bulan ini, memperbarui anggaran keluarga di aplikasi sederhana.

However, that sounds incomplete or context-dependent by itself. In a full standalone sentence, keeping kami is more natural and clearer.

Indonesian often omits pronouns when context is obvious, but explicit subjects are still very common.

Indonesian does not have articles like the or a/an in the same way English does.

So:

• anggaran keluarga can mean family budget or the family budget
• aplikasi sederhana can mean a simple app or the simple app

The exact meaning depends on context.

In this sentence, English naturally uses the family budget and a simple app, but Indonesian does not need separate words for those articles.

Yes.

Aplikasi can mean:

• application in a more formal sense
• app in everyday modern usage

In this sentence, app is probably the most natural English translation, because the context sounds like a digital tool for budgeting.

So di aplikasi sederhana is very naturally understood as in a simple app.

Yes, it sounds natural and correct.

It has a slightly neat, written feel because of features like:

• pada at the beginning
• the full pronoun kami
• the complete phrase aplikasi sederhana

In very casual conversation, a speaker might say something shorter or looser, but the sentence as given is fully natural standard Indonesian.
