Makanan ini masih layak dimakan.

Both are possible, but they do slightly different things.

• makanan ini = this food
• ini makanan = this is food / this is the food

In your sentence, makanan ini is a noun phrase, where ini comes after the noun in Indonesian. That is normal for demonstratives:

• buku ini = this book
• rumah itu = that house
• makanan ini = this food

So Indonesian usually puts ini and itu after the noun they describe.

Masih means still.

So in this sentence, it gives the idea that the food is still fit to be eaten, usually implying that someone might have doubted it because it is old, leftover, or near expiry.

Examples:

• Saya masih di rumah. = I am still at home.
• Dia masih tidur. = He/She is still sleeping.
• Makanan ini masih layak dimakan. = This food is still fit to be eaten.

So masih often adds a sense of continuation.

Layak means something like worthy, proper, suitable, or fit.

In this sentence, layak dimakan means fit to be eaten or suitable for eating.

You may also see layak in other contexts:

• layak huni = fit to live in / habitable
• layak pakai = fit for use / usable
• layak tonton = worth watching

So layak often appears with another word that explains fit for what.

Because dimakan is the passive form of makan.

• makan = to eat
• dimakan = to be eaten

So:

• layak makan would sound like fit to eat in the sense of fit enough to do the eating, which does not make sense for food.
• layak dimakan means fit to be eaten, which is exactly what we want.

This is one of the most important things to notice in the sentence.

Dimakan is formed with the prefix di- + makan.

This di- marks a passive verb in Indonesian.

• Saya makan makanan itu. = I eat that food.
  Here, makan is active.
• Makanan itu dimakan saya. = That food is eaten by me.
  Here, dimakan is passive.

In your sentence, the focus is on the food, not on who eats it, so the passive is natural:

• Makanan ini masih layak dimakan.

It is like English This food is still suitable to be eaten.

No. They look the same, but they are different.

1. di- as a prefix is attached to a verb:

   • dimakan = eaten
   • dibuka = opened
   • ditulis = written

2. di as a preposition is written separately:

   • di rumah = at home
   • di meja = on the table
   • di Jakarta = in Jakarta

So:

• dimakan = one word, because di- is a prefix
• di rumah = two words, because di is a preposition

This is a very common point for learners.

Indonesian often does not use a verb meaning to be in simple statements.

English says:

• This food is still fit to be eaten.

Indonesian can simply say:

• Makanan ini masih layak dimakan.

There is no need for a word like is.

This is very normal in Indonesian, especially in sentences where one noun is described by an adjective or phrase:

• Dia sakit. = He/She is sick.
• Rumah itu besar. = That house is big.
• Makanan ini masih layak dimakan. = This food is still fit to be eaten.

Yes, absolutely. That is a very common alternative.

• masih layak dimakan = still fit to be eaten
• masih bisa dimakan = can still be eaten / still edible

The difference is nuance:

• layak dimakan sounds a bit more formal or evaluative, like saying it is suitable or safe enough
• bisa dimakan is more everyday and practical: you can still eat it

So both are natural, but layak dimakan can sound slightly more formal, careful, or objective.

Yes, it is a very common and natural combination.

Indonesian often uses layak + passive verb or descriptive expression:

• layak digunakan = fit to be used
• layak dikonsumsi = fit for consumption
• layak dimakan = fit to be eaten

So this is not a strange or unusual phrase. It is a normal way to talk about whether food is safe or suitable to eat.

Yes. Dimakan can simply mean is eaten or gets eaten, depending on context.

Examples:

• Nasi itu dimakan anak saya. = That rice was eaten by my child.
• Daun itu dimakan ulat. = The leaf is eaten by caterpillars.

But in layak dimakan, it does not focus on who eats it. It just means the food is suitable for being eaten.

So the passive form here is more about the condition of the food than about the eater.

In this sentence, masih most naturally comes before the part it modifies:

• Makanan ini masih layak dimakan.

That is the standard and most natural version.

Learners should think of masih as coming before the adjective or verb phrase:

• masih bagus = still good
• masih hidup = still alive
• masih layak dimakan = still fit to be eaten

Moving it elsewhere would usually sound unnatural or change the emphasis.

It can do both, depending on context.

• makanan can mean food in a general sense
• it can also refer to a food item, dish, or something edible

In Makanan ini masih layak dimakan, it most naturally means this food or this item of food.

Also note:

• makan = eat
• makanan = food

The ending -an often helps form a noun, so makanan is a noun related to makan.

It is mostly neutral, with a slightly formal feel because of layak.

• Makanan ini masih layak dimakan. = neutral to slightly formal
• Makanan ini masih bisa dimakan. = more everyday and casual

You might hear layak dimakan in:

• product checks
• health/safety discussions
• news
• written recommendations
• careful everyday speech

So it is perfectly natural, just a little more formal than the most conversational option.
