Selada itu masih segar karena baru dibeli pagi ini.

In Indonesian, itu often comes after the noun when it means that/the in a specific sense.

• selada itu = that lettuce / the lettuce
• not usually itu selada in this kind of sentence

So selada itu refers to a particular lettuce already known from context.

Masih means still.

So:

• masih segar = still fresh

It shows that the freshness continues up to now. This is very common in Indonesian:

• masih panas = still hot
• masih buka = still open
• masih tidur = still sleeping

Indonesian often does not use a verb like to be in simple descriptive sentences.

So:

• Selada itu masih segar literally looks like That lettuce still fresh
• but naturally means That lettuce is still fresh

This is normal in Indonesian when describing something with an adjective or noun.

Examples:

• Dia sakit = He/she is sick
• Rumahnya besar = His/her house is big

Karena means because.

It introduces the reason:

• Selada itu masih segar = the main statement
• karena baru dibeli pagi ini = the reason why

So the structure is:

[statement] + karena + [reason]

Example:

• Saya tidak datang karena sakit. = I didn’t come because I was sick.

Here, baru does not mean new in the adjective sense. It means just / recently.

So:

• baru dibeli = just bought / was only recently bought

Compare:

• baju baru = new clothes/shirt(s) → baru = new
• baru datang = just arrived → baru = just/recently

The meaning depends on context and position.

Dibeli is a passive form.

• membeli = to buy / buys (active)
• dibeli = to be bought / bought (passive)

In this sentence, the focus is on the lettuce, not on who bought it:

• baru dibeli pagi ini = just bought this morning / was just bought this morning

If you used membeli, you would need a buyer as the subject, for example:

• Saya baru membeli selada itu pagi ini.
  = I just bought that lettuce this morning.

Indonesian often leaves out the agent when it is unknown, obvious, or unimportant.

So baru dibeli pagi ini naturally means:

• (it was) just bought this morning

The sentence cares more about the result — the lettuce is fresh — than about the person who bought it.

This omission is very common in Indonesian passive expressions.

Pagi ini means this morning.

• pagi = morning
• ini = this

Together they form a time expression.

Other similar examples:

• siang ini = this afternoon
• malam ini = tonight / this evening
• hari ini = today

Indonesian is quite flexible with time expressions, but putting them at the end is very common and natural.

So:

• baru dibeli pagi ini = just bought this morning

You could also move the time phrase earlier in some contexts, but the original version sounds very normal.

For example:

• Selada itu masih segar karena pagi ini baru dibeli.

That is understandable too, but the original sentence is smoother and more typical.

No. Segar usually means fresh, and it can be used for several things:

• food: sayur segar = fresh vegetables
• air/weather/feeling: udara segar = fresh air
• appearance/condition: terlihat segar = looks fresh/refreshed

In this sentence, it means the lettuce is fresh in the food sense.

By itself, selada can mean lettuce in a general sense. But with itu, it becomes specific:

• selada = lettuce
• selada itu = that lettuce / the lettuce

So in this sentence, it refers to a particular lettuce understood from the context.

A useful breakdown is:

• Selada itu = topic/subject noun phrase
• masih segar = predicate description
• karena = because
• baru dibeli pagi ini = reason clause

So the pattern is roughly:

[noun phrase] + [description] + karena + [passive reason clause]

That makes the sentence very natural and compact in Indonesian.
