KATA PENGANTAR

Ucapan syukur saya panjatkan kepada Tuhan Yang Maha Esa sebab atas

rahmat dan karunia-Nya saya dapat menyelesaikan laporan praktikum Teknologi

CNC dengan pembahasan “ Mesin Turning (Bubut)”.

Saya ingin berterima kasih kepada asisten laboratorium praktikum CNC, dan

Bapak Ir. Rosehan, M.T. Selaku pembimbing dan penilai laporan praktikum ini, yang

telah memberi pengarahan kepada saya. Saya juga berterima kasih kepada orang tua

kami yang telah mendukung saya selama praktikum ini berjalan dan kepada semua

pihak lain yang telah membantu saya dalam mengerjakan laporan praktikum ini

hingga selesai.

Semoga laporan praktikum ini dapat memenuhi standar penilaian yang telah

ditentukan dan dapat bermanfaat bagi setiap orang yang membacanya.

Akhir kata, saya minta maaf apabila ada kekurangan dalam laporan praktikum

ini. Kritik dan saran dari Bapak dan para pembaca senantiasa saya harapkan demi

perbaikan di masa mendatang. Terima kasih.
