Selepas tamat kursus ini, saya berharap dapat sijil yang baik untuk permohonan kerja.

Literally:

• selepas = after
• tamat = finished / finish / end
• kursus ini = this course

So the phrase means after this course ends or after finishing this course.

In natural English, you would not usually translate it word-for-word. You would normally say something like After finishing this course....

In Malay, demonstratives like ini (this) and itu (that) usually come after the noun:

• kursus ini = this course
• rumah itu = that house
• buku ini = this book

So kursus ini is the normal Malay word order.

This is a very common learner question.

tamat can function as finished / end / over, and Malay often uses compact expressions like this.

So:

• Selepas tamat kursus ini = after this course ends / after finishing this course

But you could also say:

• Selepas menamatkan kursus ini = after finishing this course
• Selepas kursus ini tamat = after this course ends

These are slightly different in structure:

• menamatkan kursus ini focuses on you finishing the course
• kursus ini tamat focuses on the course ending
• selepas tamat kursus ini is a shorter, compressed way that is common and understandable

Malay often leaves out information that is already clear from context.

In this sentence, the subject saya appears in the main clause:

• saya berharap... = I hope...

Because of that, the listener naturally understands that the speaker is talking about their own situation. So Malay does not always need to repeat I in the earlier part.

English often prefers to make that clearer with After I finish this course..., but Malay can be more economical.

This pattern is very common.

• saya = I
• berharap = hope
• dapat = get / be able to

So saya berharap dapat... can mean:

• I hope to get...
• I hope I can get...
• I hope to be able to...

In this sentence, it means I hope to get a certificate.

This is a natural Malay structure.

All three are possible, but they feel a little different:

• dapat = get, obtain; very common and natural in everyday Malay
• mendapatkan = obtain; more formal or more explicit
• menerima = receive; focuses more on receiving something from someone or an institution

So:

• berharap dapat sijil = everyday, simple
• berharap mendapatkan sijil = a bit more formal
• berharap menerima sijil = emphasizes receiving the certificate

In normal speech, dapat is very common.

Malay does not have articles like a, an, and the in the same way English does.

So:

• dapat sijil can mean get a certificate or get the certificate, depending on context

If you really want to emphasize one certificate, you could say:

• dapat satu sijil = get one/a certificate

But most of the time, Malay simply leaves the article unstated.

yang links a noun to a description. Here it introduces the modifier baik.

• sijil = certificate
• yang baik = that is good

So sijil yang baik means a good certificate or more literally a certificate that is good.

In Malay, yang is very common when adding a descriptive phrase. It helps make the phrase sound complete and clear.

It is understandable, but it may sound a little vague.

A native English speaker may also feel that a good certificate is slightly unclear. Do you mean:

• a certificate from a good course?
• a recognized certificate?
• a certificate with good results?
• a certificate that helps with job applications?

Depending on what you mean, Malay might sound more natural with:

• sijil yang diiktiraf = a recognized certificate
• sijil yang bernilai = a valuable certificate
• sijil yang boleh membantu dalam permohonan kerja = a certificate that can help with job applications

If you mean good results, then keputusan yang baik may be better than sijil yang baik.

It means for job application purposes or for job applications.

Breakdown:

• untuk = for
• permohonan = application
• kerja = work / job

So permohonan kerja means job application.

Even though English often says job applications in the plural, Malay commonly uses the singular form in a general sense. So untuk permohonan kerja can naturally mean for applying for jobs or for job applications in general.

It is understandable, but many speakers might adjust it depending on the exact meaning.

Original:

• Selepas tamat kursus ini, saya berharap dapat sijil yang baik untuk permohonan kerja.

Possible more natural versions:

• Selepas menamatkan kursus ini, saya berharap dapat memperoleh sijil yang diiktiraf untuk permohonan kerja.
• Selepas kursus ini tamat, saya berharap mendapat sijil yang boleh membantu dalam permohonan kerja.

If you mean good results rather than just a good certificate, then a better sentence might be:

• Selepas menamatkan kursus ini, saya berharap mendapat keputusan yang baik untuk membantu dalam permohonan kerja.

So the original sentence is understandable, but a native speaker might choose a more precise phrase than sijil yang baik.
