Sarung tangan pakai buang melindungi tangan.

Yes. Sarung tangan is a fixed noun phrase meaning glove or gloves.

Literally:

• sarung = cover, sheath, casing
• tangan = hand

So the literal idea is something like a hand-covering. Malay often forms everyday nouns this way, by combining simple words into a set phrase.

Because the two instances are doing different jobs:

• In sarung tangan, tangan is part of the noun phrase meaning glove(s)
• At the end, tangan is the thing being protected: hands

So the sentence structure is basically:

• Sarung tangan pakai buang = disposable glove(s)
• melindungi = protect(s)
• tangan = hands

This kind of repetition is completely normal in Malay.

Pakai buang means disposable.

Literally, it comes from:

• pakai = use, wear
• buang = throw away

So the idea is use and throw away. In natural English, we usually translate it simply as disposable.

Because in Malay, modifiers usually come after the noun.

So:

• sarung tangan pakai buang = glove(s) disposable = disposable gloves

This is a very common pattern in Malay. Compare:

• rumah besar = house big = big house
• baju merah = shirt red = red shirt

Melindungi means to protect or protects.

It comes from the root:

• lindung = protect, shelter, cover

The form melindungi is a derived verb:

• meN- is a common active verb prefix
• -i is a suffix often used with transitive verbs, especially when something is being affected or covered/protected

So melindungi tangan means protect the hands.

You do not usually use bare lindung in a normal sentence like this.

Malay often leaves those ideas unstated.

Malay does not use articles like English a and the in most cases, and it also does not need an auxiliary verb like do here.

So:

• Sarung tangan pakai buang melindungi tangan naturally means
• Disposable gloves protect hands or more naturally in English,
• Disposable gloves protect the hands
• Disposable gloves protect your hands

English usually has to add little grammar words that Malay does not need.

It can be either, depending on context.

Malay nouns usually do not change form for singular vs. plural. So:

• sarung tangan can mean glove or gloves
• tangan can mean hand or hands

In this sentence, English would most naturally interpret it as a general statement:

• Disposable gloves protect hands or
• Disposable gloves protect your hands

If Malay wants to make plurality especially clear, it can do so with context, numbers, or reduplication, but it often does not need to.

You should think of it as one noun phrase:

• sarung tangan = glove(s)
• pakai buang = disposable

Together:

• sarung tangan pakai buang = disposable glove(s)

That is the subject of the sentence.

Then:

• melindungi tangan = protects hands

So the whole sentence is built very simply:

• [Subject] + [Verb] + [Object]

Grammatically, Malay itself does not force singular or plural here, so that reading is possible in a very abstract sense.

However, in normal usage, this sentence is most likely understood as a general statement about disposable gloves as a type of item:

• Disposable gloves protect hands

If you wanted to be more explicitly singular, Malay would often use a classifier or another word, for example:

• sehelai sarung tangan for one glove

Because of the word order.

The sentence follows a common Malay pattern:

• Sarung tangan pakai buang = subject
• melindungi = verb
• tangan = object

So after the verb melindungi, the noun that follows is understood as what is being protected.

It is understandable and grammatical, but depending on context, Malay speakers might also say similar things in other ways.

For example, they might say:

• Sarung tangan pakai buang melindungi tangan anda = Disposable gloves protect your hands
• Sarung tangan pakai buang digunakan untuk melindungi tangan = Disposable gloves are used to protect hands

So the given sentence is fine, but in real life speakers may choose a version that sounds more specific or more formal depending on the situation.
