Yang saya ingat dari rapat itu adalah saran guru.

In this sentence, yang turns the clause saya ingat dari rapat itu into a noun-like phrase.

So yang saya ingat dari rapat itu means what I remember from that meeting or the thing I remember from that meeting.

This is a very common Indonesian pattern:

yang + clause = what / the thing that ...

For example:

Yang saya suka = What I like
Yang dia bilang = What he said

This structure is used for focus or emphasis.

The pattern Yang ... adalah ... is similar to English What ... is ...

So:

Yang saya ingat dari rapat itu adalah saran guru
means something like:
What I remember from that meeting is the teacher’s suggestion.

If you said:

Saya ingat saran guru dari rapat itu

that would simply mean I remember the teacher’s suggestion from that meeting, without the same focused, explanatory feel.

Adalah links two noun phrases, like a formal version of is in an equation-type sentence.

Here it connects:

Yang saya ingat dari rapat itu
and
saran guru

So the structure is:

X adalah Y = X is Y

In everyday speech, adalah is often omitted if the meaning is already clear. But in formal or careful Indonesian, it is common and natural here.

You can often leave it out, especially in casual speech:

Yang saya ingat dari rapat itu saran guru.

That is understandable, but adalah makes the sentence clearer and more formal.

So:

with adalah = more formal, more explicit
without adalah = more conversational, sometimes less polished

Because ingat by itself is very commonly used to mean remember.

In everyday Indonesian:

saya ingat = I remember

The form mengingat exists, but it often sounds more formal and can have a slightly different feel, such as to recall or to take into consideration, depending on context.

So in this sentence, saya ingat is the normal and natural choice.

Here dari means something like from in the sense of coming from or taken from that meeting.

So yang saya ingat dari rapat itu means what I remember from that meeting.

Compare:

dari rapat itu = from that meeting
pada rapat itu = at that meeting
tentang rapat itu = about that meeting

So dari is the best choice if you want to express the source of the memory.

Because Indonesian demonstratives usually come after the noun.

So:

rapat itu = that meeting
guru itu = that teacher
buku ini = this book

This is normal Indonesian word order:

noun + ini / itu

not usually this/that + noun the way English does it.

The most natural meaning is the teacher’s suggestion or advice from the teacher.

In Indonesian, two nouns together often show a relationship like possession or association:

saran guru = the teacher’s suggestion/advice
buku siswa = the student’s book
kantor guru = the teacher’s office

It would usually not mean a suggestion for the teacher. If you wanted that, you would more likely say:

saran untuk guru

Because Indonesian usually does not use a special possessive ending like English does.

Instead, it often puts the possessed thing first and the possessor second:

buku saya = my book
rumah mereka = their house
saran guru = the teacher’s suggestion

So saran guru is a normal Indonesian way to express possession or close association.

By itself, saran does not clearly mark singular or plural. Indonesian nouns usually do not change form for number.

So saran guru could mean:

• one suggestion
• advice in general
• possibly several suggestions, depending on context

If you really want to make it clearly plural, you can say:

saran-saran guru

But often Indonesian leaves that to context.

Yes, but the tone changes.

saya is more neutral, polite, and suitable for formal or semi-formal situations.
aku is more personal, casual, and informal.

Since this sentence includes adalah and talks about a rapat or meeting, saya fits the tone better.

So:

Yang aku ingat dari rapat itu adalah saran guru
is possible, but it sounds more casual and personal.

Yes. Even if the core meaning stays the same, English can phrase it differently depending on style.

Possible natural translations include:

What I remember from that meeting is the teacher’s suggestion.
What I remember from the meeting is the teacher’s advice.
The thing I remember from that meeting is the teacher’s suggestion.

That happens because Indonesian often leaves some things, such as article choice and number, to context.
