About Verb[せる・させる]

In order to express that someone was 'made to do', or 'let do' something, the auxiliary verbs せる and させる will be used. The meaning that せる and させる will convey (when attached to a verb) is called 使役(しえき) (causative, employment, or using) in Japanese.
A common misconception is that せる and させる are standard conjugations of each verb. However, these auxiliary verbs should be thought of as having their own meaning, in a similar way to how たい, ない, , です, and other auxiliaries each have their own meanings.
In order to use these grammar structures, remove the る from る-Verbs, and then add させる. For う-Verbs, change the last kana to the あ sound kana from within the same column (except for う, which becomes わ), and then add せる (る becomes ら, む becomes ま, く becomes か, etc.).
  • 息子(むすこ)野菜(やさい)()させる
    I make my son eat vegetables.
  • 友達(ともだち)にトマト(そだ)させる
    I make my friend grow tomatoes.
  • 忘年会(ぼうねんかい)先輩(せんぱい)たち後輩(こうはい)(うた)(うた)わせた
    At the end of year party, the seniors made the juniors sing a song.
  • 友達(ともだち)(わたし)携帯(けいたい)(こわ)したので(あたら)()わせる
    Since my friend broke my phone, I will make them buy me a new one.
As usual, する and () have special conjugation rules. する will be replaced completely by させる (in a similar way to how できる completely replaces する in the 'potential' form). () will become ()させる.
  • (いや)仕事(しごと)後輩(こうはい)させる
    I let my juniors do the work that I don't want to do.
  • (おや)心配(しんぱい)させることしてはいけない
    You should not do anything that would make your parents worry.
  • 夜遅(よるおそ)くに会社(かいしゃ)()させるのはよくない
    It is not good to make people come to the company late at night.
  • (いぬ)()、こっちに()させる
    To call the dog and make it come to you.
Caution
With causative, either , or can mark the doer of the action that せる, or させる is linked to (not が). This is because the actual 'doer' of the action is considered to be the person that is making/letting someone perform that action. will usually imply that someone was 'let' do something, while implies 'make'.
  • 誰か心配(しんぱい)させる
    To let someone worry about you.
  • 誰か心配(しんぱい)させる
    To make someone worry about you.
Fun Fact
Because the actual 'doer' in causative verb sentences will be marked with (as is always the case), the literal translation of せる and させる is closer to the following:
(A) が (B) 楽しませる - For (A) to cause fun 'in' (B).
(A) が (B) 楽しませる - For (A) to cause fun 'through' (B).
It is these standard meanings of the particles (a location) and (a target) that will create the 'let', or 'make' nuance when using せる, or させる.

    just to clarify, based on the notes in the grammar point I was led to believe

    先生が私をコヒーを作らせました。would mean, my teacher made me make coffee - if を in fact carries the nuance of to make someone do something.

    But my teachers are saying the correct sentence is actually

    先生が私にコヒーを作らせました。Which can mean either let or made with the differentiator either being context or a 〜て下さった・〜てくれった to imply having done me the favor of letting me.

    Hi everyone! I have a question. How can you turn this into negative? For example, if I want to say “XX person didn’t permit YY person to do this and that”? Thanks!

    Good question! In this kind of sentence, most of the time it will be implied that someone did not do something ‘for you’, so you would combine させる with てくれる.

    お母さんは私にダンスの習い事をさせてくれなかった。
    ‘My mom didn’t let me do dance practice’

    If you were talking about someone else, you would probably use the てあげる structure instead of くれる. or just させなかった by itself.
