INTRODUCTION
BBM is a very popular chat facility [7] in the process of communicating through text messages, pictures and videos so that the process of communication in the interaction between users can be carried out actively in virtual world.One technology that is used is the chat facility available on smart phones such as BBM.BBM Chat is utilized very effectively by the students especially for the learning process in the exchange of information both material and knowledge sharing.
In entire, the student's personality [6] can be seen from the way they communicate, as a way to exchange information with other friends.Previously, the information exchange process between students used SMS, which has some limitation in sending picture or video.Now, many students use BBM in the learning process or sharing knowledge.In the study the effect of the BBM on academic achievement, the effect of BBM is examined significantly to know the improvement of academic achievement [9] In the SMK Health PGRI Denpasar.Community students [10] can get more information through BBM .This Research is about the influence of BBM on academic achievement, using quantitative methods by distributing questionnaires from a random sample of the student population SMK health PGRI Denpasar.Quantitative research method can be interpreted as a research method based on positive philosophy, used to examine the population or a particular sample, sampling technique is generally done at random, using a data collection [3] instrument of research, analysis of quantitative data in order to test the hypothesis that is set.This research studies the effect of BBM with academic achievement, to determine the positive and negative influences of BBM (Blackberry Messenger), and learning to use the BBM and increase academic achievement using BBM.
In order to gain insight into the effect of BBM to increase academic achievement in this paper, the following structure is organized.In the second part some background information about the main concept paper will be provided.A more detailed description of the research method used is presented in section 3. Furthermore, the result of research conducted is presented in Section 4. In section 5 the conclusions are drawn.

II. BACKGROUND
In this section, every concept and its relationship with the problem at hand are explained.

A. Role of Information Technology

B. Black Berry Messenger
BlackBerry Messenger, abbreviated as BBM, is instant messenger application available to BlackBerry device users.This application [7] features the ability to adopt a popular activity among users of mobile devices.

C. Benefit of Learning Media
In a learning process, two very important [12]elements are the method of teaching and teaching media, in which these two aspects are interrelated.Selection of one particular teaching method of teaching will affect the type of media used, although there are other aspects that must be considered in choosing the media, among others, the purpose of teaching, types of tasks and a response is expected to take place controlled by the students after teaching and learning context includes the characteristics students.Nevertheless, it can be said that one of the main functions of teaching media is as a teaching aid that also affect the conditions, and the learning environment organized and created by teachers.www.ijacsa.thesai.org

D. Productivity
Productivity is the relationship between [2] the amount of output and input quantity for expected output result, it is essentially a measure of the effectiveness and efficiency of the organization in generating output based on those resources available.Productivity is very important for the long-term and profitability, capable to increase if managed hilistikly and systematicly.Identification and measurement of productivity is estimated in accordance with output and input.In productivity output may be expressed in physical quantities, the output can be expressed in physical units, while the input is an act that consists of resources used to produce output, a very common form of input, for example can, be seen from the workforce.

E. Correlation
Correlation between variables [5]in the mentioned research methodology, is divided into three types, namely the is symmetrical relationship, asymmetrical relationship and reciprocal relationship.Correlation is one of the statistical analysis used to find the relationship between two quantitative variables.Correlation analysis is the study of the discussion about the degree of relationship or the degree of association between two variables, such as variables X and Y.

III. RESEARCH METHOD
The research is conducted at SMK Health PGRI Denpasar for 3 months from March -May 2015.

A. Place dan Time Research
The research is conducted at SMK PGRI Denpasar Health for 3 months from March -May 2015

B. Systematics Research
Stages of systematic research as follows: 1) The first stage is the process of identifying things that become factor in the using system of BBM (BlackBerry Messenger) in the field.This process is carried out by performing understanding in the field, literature studies, and previous research studies.Results of the identification process are the analysis of field conditions regarding the use of BBM (Black Berry Messenger).
2) The next step is the establishment of the conceptual model and research plan.In the second stage where the process is carried out is variable identification, the relations among the constructs, as well as the preparation of the research hypothesis.Results of the second stage are a list and description of the variables as well as research instruments.Research instruments adapted to the description of the variables.
3) The next step is data collection, hypothesis testing, and the interpretation of test results.Results of testing the hypothesis that the hypothesis is accepted or rejected.
4) The last process is making a conclusion.Systematic research can be show by Figure 1.

C. Data Collection Technique
Data was collected by distributing questionnaires to users of BBM (Black Berry Messenger).Samples taken from the Student of SMK Health PGRI Denpasar sampling technique is simple random sampling.This technique is used [8]when the population has members / elements that are not homogeneous and stratified proportional.

D. Variable Research
There are two variables in this study, the use of BlackBerry Messenger and Achievement.The relationship of the four variables is as shown in Figure 2.

Fig. 2. Relation Model Variable
Definitions of these variables can be explained as follows:

1) Group Discussion
Group discussion is a feature owned by BBM in a group chat where there are some members who have similarity aim to be able to communicate simultaneously to chat, sharing video and image.

2) Chat, Sending Images and files
Chat, sending images and files are features that are used in personal chat, in this case between two or more personals can communicate and chat to discuss the topic.

3) Recent Updates
Recent Updates is facility that is most often used, in which the member who is in a particular BBM will be seen doing activity of making Personal Message Display Picture or change will be seen in the recent updates

4) Academic Achievement
The student academic activity using communication technology is one of the key to improve academic achievement, such as in increasing the learning liveliness value.

E. Hypothesis Research
Based on the hypothesis, the variables will be demonstrated in this study are as follows: H0:The use of BBM (Black Berry Messenger) and significant positive effect on students Academic Achievement in SMK Health PGRI Denpasar H1: The use of BBM (Black Berry Messenger) had no effect on students academic achievement in SMK Health PGRI Denpasar

F. Analysis Technic and Hypothesis Test
The analysis technique used is the technique of Kendall's Tau correlation analysis.Kendal Tau correlation is used to locate and test the hypothesis relationship between two or more variables if the data in the form ordinal or ranking.In this study, the data form is in scale used is Likert ordinal measurement.Tools used to calculate the correlation coefficient Kendal Tau is SPSS 20.
Reliability test data used [11] by Cronbach Alpha.Cronbach's alpha was developed by Lee in 1951 to provide a measure of internal consistency test or scale.The value of Cronbach Aplha expresses as a number between 0 and 1. www.ijacsa.thesai.org According to [4] the value of alpha can be interpreted as follows.Table I    To make it easier to observe the number, then the data is visualized in the form of pie charts, as shown in Figure 2.Based on these data, it is known that the data analyzed in this study largely derived from female respondents.Not yet known about the effect of gender imbalance respondents to the results of the analysis.In the next study to do research on the influence of gender on using BBM.Based on data from Table III, it is known that the majority of respondents were from Grade XII as much as 67% and as much as 33% Grade XI.If the data is visualized in a bar chart, the obtained Figure 4 below.The interpretation of the results is referring to the standard interpretation of internal consistency [4].Based on the above results, it can be interpreted that there is a positive relationship between the variables group_discusion with academic_achievement with large coefficient is equal to 0.356.Chat_sending_files_and_images variables also have a positive relationship with academic_achievement, with a coefficient of 0.311 and a variable Recent_updates with academic_achievement positive relationship with koefisienn relation of 0386.Z value of the third relationship is less than 0.05, suggesting that the relationship between these variables is significant.If the described relationship of these variables on figure 7: With the above test results, it can be concluded that the H0 is rejected and H1 accepted, namely the use of BlackBerry Messenger in a positive and significant effect on achievement.This shows that the learning media BBM (Black Berry Messenger) is best used to increase academic achievement.
