ABSTRAK
Pada tugas akhir ini dibuat sebuah mesin magnetic coolant separator yaitu sebuah
mesin yang mampu memisahkan material besi dengan coolant secara otomatis.
Latar belakang pembuatan mesin magnetic coolant separator ini karena konsumsi
pendingin sangat tinggi, suatu sistem sangat dibutuhkan, sehingga dapat
mengedarkan kembali pendingin yang digunakan. Tujuan dalam pembuatan mesin
magnetic coolent separator adanya mesin ini cairan pendingin pada mesin dapat
di pisahkan dari gram bekas hasil produksi sehingga kualitas cairan pendingin
tetap terjaga dan terhindar dari kotoran. Pembuatan mesin magnetic coolant
separator menggunakan cara pengumpulan suatu data atau informasi yang
berkaitan dengan suatu masalah yang akan diteliti serta tahapan proses
perancangan dan pembuatan disertai juga pengujian hasil kinerja dari mesin. Hasil
yang di dapatkan dalam pembuatan mesin magnetik coolant separator ini mampu
menarik atau memisahkan material besi dari cairan pendingin (coolant). Sehingga
kualitas cairan pendingin (coolant) tetap terjaga.
Kata Kunci : Magnetic Separator,Coolant Separator

KATA PENGANTAR
Alhamdulillah, penulis bersyukur kepada Allah, sehingga atas karunia-Nya,
penulis bisa menyelesaikan tugas akhir ini. Shalawat dan salam senantiasa
tercurah atas Nabi Muhammad shalallahu ’alaihi wa sallam.
Tugas akhir ini merupakan salah satu persyaratan memperoleh gelar Ahli Madya
pada Program Studi Teknik Mesin, Jurusan Teknik Mesin Politeknik Indramayu.
Tugas akhir ini berjudul ’Perancangan Mesin Magnetik Coolant Separator Untuk
Memisahkan gram dengan Collant secara otomatis.
Penulis mulai mengerjakan tugas akhir ini pada bulan Maret 2018, dan selesai
pada pertengahan Agustus 2018. Satu bulan terakhir, penulis gunakan alat dan
mesin di laboratorium teknik mesin.
Penulis menyampaikan terima kasih kepada semua pihak yang telah membantu
penulis dalam penyelesaian tugas akhir ini. Secara khusus penulis mengucapkan
terima kasih kepada:
1. Kedua orang tua saya.
