INTRODUCTION
Vocational High School (VHS) is one of the formal education that aims to educate learners to work independently or as a skilled job seeker, professional, and highly disciplined by the demands of the working world. In the Law of the Republic of Indonesia Number 20 the Year 2003 on National Education System especially article 15 mentions particular purpose high schools are preparing learners, mainly to work in a specific field of competence as job seekers with their expertise. These objectives can be achieved if supported by a good quality of learning.  Dimyati & Mudjiono (2006) stated that the daily activities of students are learning. The learning process determines the quality of teaching received by students. Principal in learning is active learning methods are used. Gredler (2011) emphasizes that environmental influences be dominant in the learning process, studies of education is not just an academic exercise, studies of knowledge is an essential aspect of both the individual and society. Learning is also the basis for the advancement of society in the future. The primary task of the teacher is learners by conditioning the learners to learn actively explore the potential in him to be able to develop the maximum (Joyce & Weil, 1980). The learning environment conditions are a beneficial learning process for students in class XII specifically for practical exam preparation. One of the subjects that must be mastered by students in class XII majoring in Computer and Network Engineering is Server Administration. Server Administration practice learning has much material that requires participants to deliver content that conveys and practices it to be more independent and think critically. Problems that often occur, too much learning content made the participants uncontrolled and focused, making the decisions of the students fail. Students not controlled in tasks or input during learning. Students who do not have individual notes when the material presented is not well absorbed by students and very good for learning outcomes. There is needed control by the teacher when practicing or outside of school to find out the ability of students, not only in class but also to help students learn outside of school.
In learning practice students tend to stand out for competition, most of the performance in carrying out their duties is good, but their nature is only temporary. In other conditions learners whose learning goals focus on improving individual performance and skills development, usually, distribute their performance to hard work in learning. The learning objectives of students in the Server Administration practice learning so far have not been well monitored by the teacher, which results in students being less attentive to themselves. Students tend to be passive in collecting assignments given by the teacher. Through Google Classroom the learning conditions of students are expected to be monitored continuously, and students are required to fulfill their duties in learning actively (Iftakhar, 2016). Google classroom is one of e-learning that describes classes in cyberspace. Monitoring inside or outside of learning by Google classroom can be done online, besides students can also get announcements, materials, assignments, quizzes, value information and online discussion facilities (Izenstark & Leahy, 2015). Through Google classroom, students are expected to pay more attention to learning goals and can improve student learning outcomes in Server Administration subjects.

RESEARCH METHOD
The method used in this research is the research and development (Borg & Gall, 1983). The model used in this research is the development of conceptual models (Johnson & Henderson, 2002). Analytically, conceptual models that provide components of the product that will develop and the linkages between segments. The theoretical model is closely related to the concept will be implemented and provide an overview of interaction that will be examined to assess systematically empirical fact.
Online learning model development procedure is carried out in several stages, the test of the experts (expert judgment), field testing is limited, and the primary field test. The study would require the development of a series of tests on the learning model. That was done to test the validity of the learning model, whether actually can be beneficial for improving the quality of learning or not. Test phase by experts aims to obtain online learning model validation designed by the practice of learning server administration, including supporting devices.

Data analysis techniques aim to process data collected from interviews and questionnaires. The data analysis divided into two types, namely the analysis of qualitative data and quantitative data analysis. Limited field tests and the main squares are used to determine the valid aspects, excellent and exciting. Test the validity obtained from the validation experts, the enforceability of the test derived from a limited field of subject teachers' administration server, test the attractiveness of the finite field was obtained from 6 learners XII TKJ 1 and 6 learners XII TKJ 2. As for the aspect of effectiveness is derived from the primary field test of pretest and posttest.
Data analysis techniques aim to process data collected from interviews and questionnaires. The data analysis divided into two types, namely the analysis of qualitative data and quantitative data analysis. Qualitative data analysis used in the study of this development is only a presentation of qualitative data from experts and respondents in field trials. Sources of qualitative data derived from interviews directly with the informant and written responses to a questionnaire filled simultaneously. Qualitative data also used as a guideline for the revision of the learning model apart from assessment questionnaire development. Quantitative data analysis Quantitative data analysis in the form of questionnaires from media experts, subject matter experts, students, and teachers from questionnaire responses from media experts, subject matter experts, students, and teachers.
The eligibility criteria of this learning model from analysis of the validation test of media and materials. The rules used to assess the development of the learning model with very decent results, decent, reasonably feasible or not feasible. The criteria implementation learning model derived from the questionnaire results with the criteria teachers, excellent, good, fair, less and did not happen. Standards for the attractiveness of this model obtained from the questionnaire results with the requirements of learners is very interesting, exciting, entertaining and uninteresting. By calculating the quantitative data analysis in the form of data from the questionnaire response or media experts, subject matter experts, learners, and teachers. The normality test is done to find out the data from each sample group normal distribution or not.
Parametric test provisions relating to the value of correlation (r) and significance level. Correlation (r) is the relationship between members of the pair and sig. is a significant level, to the rule is if sig. > 0.05, there is no relationship before and after applying the model and if sig. <0.05 then there is a relationship before and after applied to the model. Rules for paired sample t-test test before and after using the model is if sig. <0.05 then there is a significant difference, if sig <0.01 then there is a very significant difference, whereas if sig> 0.05, otherwise there is no difference.
Test completeness and learning outcomes were conducted to determine the level of mastery of learning outcomes and learning outcome after the pretest and posttest. Exhaustiveness obtained when learners are equal to or exceed the KKM on the subjects of Administration Server and the learning outcomes achieved from the percentage increase learning outcomes of students.
