Guru meminta kami mengirim tugas presentasi sebelum kelas daring dimulai.

Indonesian usually does not use articles like the, a, or an.

So:

• Guru can mean the teacher, a teacher, or just teacher, depending on context.
• tugas presentasi can mean the presentation assignment or a presentation assignment.

Context tells you which one is meant. If the speaker needed to be more specific, they could add words like:

• seorang guru = a teacher
• guru itu = that teacher / the teacher
• tugas presentasi itu = that presentation assignment

In your sentence, plain Guru is completely natural.

Because Indonesian often leaves nouns bare when the referent is already clear from context.

• Guru meminta kami... = natural if everyone knows which teacher is meant
• Seorang guru meminta kami... = emphasizes a teacher
• Gurunya meminta kami... = the teacher in a more explicitly definite sense

In real Indonesian, using just guru is very common and sounds less heavy than adding a determiner every time.

Both are possible.

• meminta kami mengirim...
• meminta kami untuk mengirim...

The version without untuk is very common and natural, especially in straightforward sentences.

Structure:

• meminta = to ask/request
• kami = us
• mengirim = to send

So the pattern is basically:

• meminta + object + verb

Examples:

• Dia meminta saya datang. = He asked me to come.
• Ibu meminta kami menunggu. = Mother asked us to wait.

Adding untuk can sound a little more explicit, but it is not necessary here.

This is a very important Indonesian distinction.

• kami = we/us, excluding the listener
• kita = we/us, including the listener

So in this sentence, kami means the teacher asked us students, but not the person being spoken to.

If the speaker included the listener in the group, they would say kita instead.

Example:

• Guru meminta kami mengirim tugas. = The teacher asked us to send the assignment.
  (You are not part of us.)
• Guru meminta kita mengirim tugas. = The teacher asked all of us, including you, to send the assignment.

The prefix meN- often forms an active verb, especially a transitive one.

Here:

• minta = ask, request

• meminta = to ask/request

• kirim = send
• mengirim = to send

In many cases, the meN- form is the normal dictionary-style verb you use in sentences with an object.

For example:

• Saya mengirim email. = I send / am sending an email.
• Dia meminta bantuan. = He/she asked for help.

The prefix changes shape depending on the first sound of the root:

• me-
• mem-
• men-
• meng-
• meny-

That is why it is meminta but mengirim.

dimulai is the di- form, often called the passive form.

• mulai = begin/start
• memulai = start something
• dimulai = be started / begin

In this sentence:

• sebelum kelas daring dimulai = before the online class begins / is started

This sounds natural because the focus is on the class as an event that starts, not on who starts it.

You may also hear sebelum kelas daring mulai, especially in casual speech, but dimulai sounds a bit more formal and polished here.

Yes, dimulai is formally a passive form, but in English the most natural translation is often just begins.

So:

• kelas daring dimulai literally has the sense of the online class is started
• but naturally it means the online class begins

This is common in Indonesian. A passive-looking form can be used when the event matters more than the person causing it.

Compare:

• Guru memulai kelas. = The teacher starts the class.
• Kelas dimulai pukul delapan. = The class begins at eight.

daring means online.

It is short for dalam jaringan, literally in the network.

So:

• kelas daring = online class
• belanja daring = online shopping

It is a standard Indonesian term, though in everyday speech many people also use borrowed forms related to English, depending on context.

Notice the word order:

• kelas daring = class online
• Indonesian modifiers often come after the noun

This is a very common Indonesian pattern: noun + noun, where the second noun modifies the first.

So:

• tugas presentasi = presentation assignment
• more literally: assignment (for) presentation

The second noun often works like an English adjective or of/for phrase.

Other examples:

• buku sejarah = history book
• kelas bahasa = language class
• rapat tim = team meeting

Depending on context, tugas presentasi could mean:

• an assignment for a presentation
• a presentation assignment
• the assignment about the presentation

The exact nuance comes from context.

Because sebelum can introduce either:

1. a time expression / noun phrase, or
2. a full clause

Here it introduces a clause:

• sebelum kelas daring dimulai = before the online class begins

That clause has its own subject and verb:

• kelas daring = subject
• dimulai = verb

You can compare:

• sebelum kelas = before class
• sebelum kelas dimulai = before class begins

Both are correct, but the second is more explicit.

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

So:

• meminta
• mengirim
• dimulai

do not by themselves mark past, present, or future.

Time is understood from:

• context
• time words
• the situation

In this sentence, sebelum kelas daring dimulai tells you the sending must happen before the class begins, but the sentence itself does not force a specific English tense without context.

That is why Indonesian often relies more on context than verb endings.

The given word order is the most neutral and natural:

• Guru meminta kami mengirim tugas presentasi sebelum kelas daring dimulai.

Basic structure:

• Guru = subject
• meminta = verb
• kami = object of meminta
• mengirim tugas presentasi = what we were asked to do
• sebelum kelas daring dimulai = time clause

You can move some parts for emphasis, but the original version is the clearest.

For example:

• Sebelum kelas daring dimulai, guru meminta kami mengirim tugas presentasi.

This is also correct, but now the time element is emphasized first.

Yes. meminta can cover both ideas.

Depending on context, it may mean:

• ask
• request
• ask for

Examples:

• Dia meminta bantuan. = He/she asked for help.
• Guru meminta kami belajar. = The teacher asked us to study.
• Mereka meminta izin. = They requested permission.

In your sentence, asked us to send or requested that we send both fit.
