1. Introduction

Computer is one medium that can help students in drill and practice activities. With the support of software in the form of programs, students can train themselves to use it properly, develop, and produce works in accordance with the capabilities, expertise, and needs. One program that can help a student is CAI. CAI (Computer Assisted Instruction) is made by creative people who create a medium of learning with learning strategies that are based on student needs, where students can obtain information/messages in a fun and personalized, because CAI provides a method of learning in the form of tutorials, drill and practice, simulations, problem solving, data base up to the games.

CAI (Computer Assisted Instruction) or CAL (Computer Assisted Learning) is defined as computer assisted learning (PBK). CAI but the term is more familiar, so henceforth the term CAI is used. There are many definitions kicking CAI or Computer Assisted Instruction. Among them is the general definition expressed by Hannafin, namely that “CAI regards to any learning situation in which the activities and learning materials delivered via computer” [1] . CAI also combines and synergizes all media consisting of text, graphics, images, video, animation, music, narration and interactivity that are programmed based on the theory of learning. An opinion about CAI, which is an interactive application program that can be used as a medium, conveys information as well as evaluation of learning media. Furthermore CAI can be used as a tool in independent learning for students. Use of CAI in learning is one of the alternative methods that attract and are able to provide a real picture of the material that is abstract [2] .

The term generally refers to all the CAI education softwares that are accessed through a computer where the user can interact with it. The computer system can present a series of learning programs to students, either in the form of information concept and practice questions to achieve certain goals, or in the student learning activities by interacting with the computer system. While in his position it can be said that CAI is the use of computers as an integral part of the instructional system, where the user is usually tied to the two-way interaction with the computer. CAI is interpreted as forms of learning that puts computers in the role of educator [3] - [5] . Meanwhile, CAI is a learning program that is created in the computer system, which conveys a pre-defined material directly to the user [6] - [8] . The subject matter already programmed can be served simultaneously between the components of the image, text, color and sound.

Activities to do with CAI include 4 main categories, namely: 1) Drill and Practice, 2) Tutorial, 3) Games, and 4) Simulation. In training activities, the computer gives questions about a topic fatherly solved by the students and the computer gives feedback based on the student’s response. Activity tutorial intends to teach new information on a topic. The game can serve as a presenter or a new lesson material as well as the reinforcement of the lessons learned through the activities of other students. In the simulation or modeling, computer simulations or models provide a concept or event to be input by the student and the computer will give a response to these inputs as the actual system will act. So CAI is learning everything that is programmed using a computer and allows the user to interact with and usually for the purpose of independent learning.

One factor determining the quality of graduates majoring in industrial engineering is the quality of the implementation of learning. Besides, the main obstacle has been the lack of teaching materials based CAI (Computer Assisted Instruction). In fact, the competence of students of the Department of Industrial Engineering in Industrial Chemistry course is still very low. Therefore we need an innovative teaching materials based CAI (Computer Assisted Instruction) in the form of an interactive CD that does not exist in the Department of Industrial Engineering in Indonesia to improve the competence of students in the subject of Chemical Industry. Thus, by using this interactive CD, students of Department of Industrial Engineering in Indonesia can increase their competence in the Industrial Chemistry Lecture.

2. Research Method

This study uses the procedures of research and development (Research and Development) is thus through the procedures and field trials. The method of research and development in principle is a process for the development of a product of education and next validated [8] - [10] . The products that will be developed and validated teaching materials Chemical Industries is based CAI (Computer Assisted Instruction). In this study testing the effectiveness, efficiency and attractiveness of teaching materials based Industrial Chemistry CAI (Computer Assisted Instruction), researchers used an assessor or observation and feedback of students, peers, and student learning outcomes. The effectiveness of the tested models of student learning outcomes by using pre-test and post-test, while the appeal is usually measured by the scale of attitudes, self-evaluation and student opinion regarding the teaching material based Industrial Chemistry CAI (Computer Assisted Instruction) in accordance with the conditions and needs.

The sampling technique used is sampling considerations (purposive sampling) which have the characteristics in classes where many students have to follow a remedial program for the course Chemical Industry. To collect data on the initial information about the student learning process Chemical Industries today as a needs analysis study represented 10 students to a preliminary study. Similarly, the early stages of field tests, the study only do one class which classes are being/well with the base average GPA is determined 3. Based on these considerations such as class field testing of teaching materials based Industrial Chemistry CAI (Computer Assisted Instruction). Planning research steps at the stage of the seventh due to the lack of researchers and according to the needs of the research itself as well as by statements Borg and Gall, development of teaching materials is a form of research and development of small-scale limited [11] - [14] . This means allowed if it gets on the seventh stage, but does not detract from the purpose to be achieved that is obtained in the form of educational products based teaching materials Chemical Industries CAI (Computer Assisted Instruction). Step-by-step development of small-scale research through three main steps: pre-development, development models and application models, as for the chart as follows (Figure 1):

Figure 1. Flow chart of this research [15] .

For data-collection efforts necessary research then developed the instrument in accordance with the needs of the data and information collected. The study consists of a grating and instrument in the form of questionnaires and tests. The data analysis technique consists of quantitative and qualitative. Quantitatively analyzed using quantitative descriptive statistics inferential analysis, while quantitative analysis with a way to describe in a narrative. Qualitative data analysis procedure performed through three stages, namely the process of data reduction, data presentation, and decision making. The resulting product is design-based teaching materials CAI (Computer Assisted Instruction) in prototype form, with the following steps:
