Slaughter man

Yesterday, I evaluated for student industrial presentation. One of the terminology that student used to define penyembelih was slaughter man. But, actually this sound is like to sembelih seorang lelaki. I just noticed to the student maybe the right word to use is slaughterer not slaughter man. Yeah!!! After the presentation finish, i try to found the accurate word for penyembelih. The correct word is slaughterer.
