           Puji Syukur kehadirat Allah SWT karena atas limpahan rahmat-Nya sehingga 
        kami  dapat  menyelesaikan  buku  ajar    Kimia  Dasar  untuk  kepentingan  perkuliahan 
        Mahasiswa Universitas  Muhammadiyah Prof. Dr. HAMKA. Buku ajar  ini disusun 
        berdasarkan yang lebih menempatkan Mahasiswa sebagai pusat kegiatan belajar (Student 
        Center). Buku ajar  ini juga dilengkapi dengan latihan soal untuk menguji pemahaman 
        mahasiswa terkait dengan materi yang terdapat pada buku ajar .  
           Kami menyadari masih banyak kekurangan dalam penyusunan buku ajar  ini. Oleh 
        karena itu, kami sangat mengharapkan kritik dan saran demi perbaikan dan kesempurnaan 
        dari buku ajar  ini.
