KATA PENGANTAR ii
Puji syukur saya panjatkan kehadirat Allah SWT, atas segala rahmat dan hidayah-Nya, sehingga penulisan laporan hasil praktikum laboratorium bahan ini dapat saya selesaikan. Penulisan laporan ini bertujuan untuk menguraikan mengenai hasil yang diperoleh selama praktikum laboratorium bahan. Tanpa
bantuan
dari
berbagai
pihak,
sulit
rasanya
saya
dapat
menyelesaikan praktek maupun penulisan laporan ini. Oleh karena itu pada kesempatan ini saya sampaikan banyak terima kasih kepada : 1. Dosen pembimbing/instruktur yang telah membimbing saya selama melaksanakan praktek di laboratorium. 2. Rekan – rekan atas kerja sama dan bantuannya baik selama praktek di laboratorium maupun selama pembuatan laporan ini. Saya menyadari atas berbagai kelemahan dan kekurangan yang ada pada saya, sehingga tidak menutup kemungkinan masih terdapat banyak kekurangan dan kesalahan dalam penulisan laporan ini. Oleh karena itu kritik dan saran dari berbagai pihak sangat saya harapkan, demi untuk penyempurnaan laporan ini selanjutnya. Namun demikian saya tetap berharap, mudah – mudahan laporan praktikum laboratorium bahan ini dapat bermanfaat baik bagi saya maupun bagi pihak lain yang memerlukannya.
