Ibu membersihkan lumut di lantai dekat keran luar agar tidak licin.

Ibu can mean different things depending on context:

• mother / mom
• a respectful form of address for an adult woman, like Mrs., ma’am, or madam

In this sentence, Ibu membersihkan..., it most naturally means Mother/Mom cleans... or The lady cleans..., depending on the situation.

Indonesian often leaves relationships unstated if they are already clear from context, so Ibu by itself can work where English might say my mother or the mother.

Membersihkan means to clean or to make something clean.

It comes from the root bersih, which means clean.

The form is:

• bersih = clean
• meN- ... -kan → membersihkan = to clean something / to make something clean

So this is a transitive verb: it normally takes an object.

In the sentence:

• Ibu membersihkan lumut = Mother cleans the moss / Mother is cleaning moss

This is different from bersih, which is just the adjective clean.

Example:

• Lantainya bersih. = The floor is clean.
• Ibu membersihkan lantai. = Mother cleans the floor.

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

So lumut can mean:

• moss
• the moss
• some moss

The exact meaning depends on context.

In this sentence, English would often naturally say the moss because it sounds like specific moss on that floor.

This is very normal in Indonesian: nouns often appear without any article at all.

This whole part describes location.

• di = at / on / in
• lantai = floor
• dekat = near
• keran luar = outdoor tap/faucet

So:

• di lantai = on the floor
• dekat keran luar = near the outdoor tap

Together:

• lumut di lantai dekat keran luar = the moss on the floor near the outdoor tap

So the sentence is talking about moss located on the floor, specifically the floor area near the outside tap.

In Indonesian, modifiers often come after the noun.

So:

• keran luar = literally tap outside → outdoor tap
• rumah besar = big house
• air panas = hot water

This is a very common Indonesian pattern: noun + descriptive word.

So keran luar sounds natural in Indonesian, even though English puts outdoor before tap.

Agar means so that, in order that, or so that ... not when used with negation.

In this sentence:

• agar tidak licin = so that it is not slippery / so it won’t be slippery

Agar and supaya are very similar, and in many everyday situations they can be used interchangeably.

For example:

• Ibu membersihkan lumut agar tidak licin.
• Ibu membersihkan lumut supaya tidak licin.

Both are natural.

Very roughly:

• agar can sound a little more formal or careful
• supaya is very common in everyday speech

Licin means slippery, slick, or smooth in a slippery way.

In this sentence, tidak licin means not slippery.

Because moss can make a floor dangerous, licin is exactly the kind of word you would expect here.

Example:

• Lantainya licin. = The floor is slippery.
• Jangan lari, licin. = Don’t run, it’s slippery.

The most natural interpretation is that it refers to the floor area near the outdoor tap.

So the idea is:

• Mother cleans the moss on the floor near the outdoor tap
• so that the floor does not become slippery / is not slippery

Indonesian often leaves this kind of subject unstated when it is obvious from context.

English usually makes it more explicit:

• ...so the floor won’t be slippery
• ...so it won’t be slippery there

Even though lantai is not repeated, it is understood.

In Indonesian, tidak is used to negate:

• verbs
• adjectives

And bukan is usually used to negate:

• nouns
• noun phrases
• identity/classification

Since licin is an adjective, the correct negation is:

• tidak licin = not slippery

Compare:

• Lantainya tidak licin. = The floor is not slippery.
• Itu bukan lantai. = That is not a floor.

So bukan licin would sound wrong in normal Indonesian.

Indonesian verbs usually do not change form for tense.

So membersihkan by itself does not tell you whether the action is:

• present: cleans / is cleaning
• past: cleaned / was cleaning
• future: will clean

The time is understood from context, or from time words if they are added.

So this sentence could be interpreted in English in different ways depending on context:

• Mother cleans the moss...
• Mother is cleaning the moss...
• Mother cleaned the moss...

If you want to make time clearer in Indonesian, you can add words like:

• sedang = currently
• sudah = already
• akan = will

Example:

• Ibu sedang membersihkan lumut... = Mother is cleaning the moss...

Just like with lumut, Indonesian normally does not use articles like the or a.

So:

• lantai can mean floor or the floor
• keran luar can mean an outdoor tap or the outdoor tap

Context tells you which one is meant.

This is one of the biggest differences from English. Indonesian is often more compact, and English translations usually need to add articles that are not present in the original sentence.

Yes, in this sentence dekat functions like near.

So:

• dekat keran luar = near the outdoor tap

Indonesian learners often notice that dekat can behave a little flexibly. It can be used in ways similar to an adjective or a preposition depending on the structure.

For practical purposes here, it is easiest to understand it as a location word meaning near.

Example:

• Rumah saya dekat sekolah. = My house is near the school.
• Dia duduk dekat saya. = He/She sits near me.

So di lantai dekat keran luar is perfectly natural Indonesian for on the floor near the outdoor tap.
