Dia baru sahaja terjatuh dan kini tidak sedarkan diri.

Yes. Dia is gender-neutral in Malay, so it can mean he, she, or sometimes even they in a very general singular sense, depending on context.

Malay usually does not mark gender in pronouns the way English does, so you need context to know whether the person is male or female.

Baru sahaja means just or has just.

It shows that the action happened a very short time ago. In this sentence, it tells you the fall happened very recently.

A few useful points:

• baru alone can already mean just
• baru sahaja adds emphasis and sounds a bit fuller
• In everyday speech, many people also say baru saja

So:

• dia baru terjatuh
• dia baru sahaja terjatuh
• dia baru saja terjatuh

are all possible, with slightly different levels of emphasis or formality.

Jatuh means fall.

Terjatuh usually suggests that the fall happened unintentionally or accidentally. The prefix ter- often gives that kind of meaning.

So:

• jatuh = to fall
• terjatuh = to accidentally fall / to end up falling

In this sentence, terjatuh is very natural because falling is normally not deliberate.

Yes, terjatuh is written as one word.

It is made from:

• ter-
  • jatuh → terjatuh

In Malay, prefixes attach directly to the base word. So you do not write it as ter jatuh.

Because in Malay, time-related adverbs like baru sahaja usually come before the verb.

So the pattern is:

• Dia baru sahaja terjatuh
• subject + time/aspect expression + verb

This is normal Malay word order.

Kini means now or currently.

It is very close in meaning to sekarang, but kini tends to sound a bit more formal, written, or news-like.

So:

• kini = now, currently
• sekarang = now

In everyday speech, many learners will hear sekarang more often.

Because tidak is used to negate verbs, adjectives, and states, while bukan is mainly used to negate nouns or noun phrases.

Here, sedarkan diri is part of a state/expression, so tidak is the correct negative.

Compare:

• tidak sedar = not conscious / not aware
• bukan doktor = not a doctor

So bukan sedarkan diri would be wrong here.

It is a set expression meaning unconscious or not conscious.

Learners often notice that this is longer than just tidak sedar, and that is true:

• tidak sedar = not aware / unconscious
• tidak sedarkan diri = unconscious; also a fixed idiomatic expression

In this sentence, tidak sedarkan diri sounds natural and strong, especially in a medical or dramatic situation.

It is best to learn it as a whole phrase, not to analyze it too literally word by word.

Yes. Saja is the common shortened form of sahaja.

So these are equivalent:

• baru sahaja
• baru saja

The version with sahaja often looks a bit more formal or careful in writing, while saja is very common in conversation.

It sounds fairly neutral to slightly formal.

That is because of choices like:

• sahaja instead of saja
• kini instead of sekarang
• tidak instead of tak

A more casual spoken version might be:

• Dia baru saja terjatuh dan sekarang tak sedarkan diri.

That version is more conversational, but the original sentence is perfectly natural, especially in writing or reporting.
