a  learning  program  in  accordance  with  the  speed  and  capabilities  of  its  own,  more independent  learning,  and  can  emphasize  mastery  learning  materials  optimally.  Sixth,
learning  in  the  form of  Interactive Digital  Book  is  a  form  of  learning  that  is  effective  and efficient in this age, because paper prices soar and many possibilities quickly broken.
2. Materials and methods
The  materials  used  in  this  study  are:  reference  and  referral  of  nerve  physiology teaching materials drawn from various sources, hardware; Notebook with Intel Core i3-350M
Processor  specs,  4  GB  DDR3  RAM,  500  GB  hard  drive,  and  monitors  with  1366  x  768 resolution; and software Windows 7 Ultimate, 3D Pageflip Pro, Flipbook Maker, Microsoft
Office 2007, Nitro PDF Pro, Format Factory, and other supporting software.
This research includes the development. The model used is the development systems of  model  that  includes  the  phases  of:  a  preliminary  study,  planning,  development,  and
product testing. Preliminary study include activities to identify the learning needs of students and  lectures  and  identify  the  characteristics  of  the  students. Planning  and  product
development activities include 1 identifying the general purpose of learning, 2 analyzing learning, 3 formulate specific goals, 4 the development of interactive learning strategies,
and  5  the  preparation  of  the Interactive  Digital  Book as  learning  materials.  Interactive Digital Book product testing is done by giving a questionnaire, developed to gather data from
expert analysis and individual test about the Interactive Digital Book products.
This  study  was  designed  to  study  the  design  of Research  and  Development  R  and D. Research phases are used in accordance with the workflow method of R and D in Sugiyono
2010. The  process  of  development Digital  Book  Interactive comprising:  analysis  of  the potential  and  problems,  the  initial  data  collection,  product  manufacturing,  early  product
validation, revision of the product, and testing the final product.
The  data  were  analyzed  by  two  different  techniques. First,  data  were analyzed qualitatively  to  the  data  from  the  literature  review,  analysis  questionnaire  needs,  and
student  characteristics. Second,  the  data  were  analyzed  quantitatively  for  data  validation results  and  individual  experts. The  technique  used  to  analyze  the  data  validation  and
individual  experts  are  descriptive statistics.The  research  data  obtained  from  observations media teaching materials first product, the product II the revised product I, and the product
III the revised product II. Data in the form of teaching material appraisal by experts and students. While the criteria for analyzing the responses to the product; Quality of End-User
Interface  Design,  Engagement, Interactivity, and Tailorability Baker  and  King,  1993  in Geissinger, 2009.
Questionnaires were given to the expert and determined student assessment, namely A if very decent. and B if worthy, C if pretty decent, D if less decent, and E if unfit, further
processed by using the formula percentages by Warsito 1992 =
× 100, where
P, , and N denote total percentage of each question, number of respondents who chose, and total number of respondents, respectively. Table 1 presents the interpretation of
classification according to the calculation of the percentage of Warsito 1992 which has been modified by researcher.
This study tests the use of Interactive Digital Book products implemented in Biology Education  Studies  Program  STKIP  Garut  located  at Jalan  Pahlawan  No.  32  Garut. Subjects
were third-year students and implemented starting in June 2014.
