This research aimsare to analyze and compare the efficiency of Indonesian Education universities by using Data Envelopment Analysis. This research consists of activities which are needs analysis, the assessment of variables, data collection mechanism, design of efficiency model and implementation of the analysis for twelve Education Universities in Indonesia. The more output is generated using the input bit will improve the efficiency of the university. The result of calculations indicates that the Education Universities in Java have averaged better efficiency compared with the Education Universities outside Java. Keywords: Efficiency, Education University, Data Envelopment Analysis I. INTRODUCTION 1.1 Background Performance of Higher Education Institutions has been the subject of growing attention in recent years. The question of how public resources should be allocated in higher education has resulted in the need for models and mechanisms that will be able to measure the highereducationinstitution efficiency. Each country has its own policyon Higher Education funding arrangements and resource allocation structure. The determination for the single university tuition fee is also a matter to be raised at the Indonesia Ministry of Education and Culture. Several studies have been conducted to address this issue at the international level. The experiment was conducted by using statistical analysis to measure the performance, while others use non-statistical instruments.The analysis of efficiency of the education sector varies substantially. Therefore it is necessary to be careful in determining the performance indicators for the analysis of efficiency for higher education. There are two main aspects in the world of higher education: first, educational institutionsoperate under different environmental conditions which are public and private university. Second, the education production sector contains many inputs and outputs.According to data in 2013, there are 92 state universities , and thousands of private universities in Indonesia (www.dikti.go.id). Higher education institutions should be treated as a unit with the same productive measurement as a business unitto evaluate the performance which requires inputs to achieve a given level of output. Some examples of the performance indicator used are the proportion of students in a given year and the tuition cost per student as an input or the number of students who graduate every year and graduate waiting time for working in the first time as an output . Input and output are needed to determine the efficiency in Higher Education Institutions. In addition, some special things attached to the education sector should also be taken into account when calculates the efficiency. The purpose of this study are to obtain the model and calculate the efficiency of higher education institutions and then also rank from most to least efficient institution which will be used to provide an input to the government in order to determine the optimal allocation of resources to the highereducation institution.In particular, the purpose of this study also want to develop a model that can be used to calculate the efficiency in Indonesian education universities using Data Envelopment Analysis method which will be developed as an important information for Indonesian goverment to improve the quality and objectivity of performance appraisal in the University of Indonesia (Altbach, 2004). II . LITERATURE REVIEW 2.1 Efficiency Assessment of Higher Education The study of university efficiency assessment has been carried out in various countries, mostly by applying the method of Data Envelopment Analysis (DEA). Result of the study using three inputs and three outputs carried outin the United States shows that the State universities have higher efficiency than private universities (Ahn et al., 1988). In a separate study by applying the DEA model with five inputs and six outputs factors ( Rhodes and Southwick, 1986) demonstrates the efficiency of public university 96 lower than the 54 private universities in the United States. Data Envelopment Analysis (DEA) is also used to assess the efficiency of the 25 best U.S. universities (Breu and Raab, 1994) and showed that DEA is the correct method for measuring the efficiency of higher education. DEA method is also used in the calculation of the efficiency of several universities in Norway in 1994, 1995 and 1996 (Fø rsund and Kalhagen, 1999), the scale of the technical efficiency of Australian universities (Abbott and Doucouliagos, 2003), the efficiency of public university of Portugal in 2003 (Afonso and Santos, 2005), the technical efficiency of 45 England universities from 1980 to 1981 and 1992/93 (Flegg et al., 2003), differences in the efficiency of the group 210 higher education institutions from eight European countries using a sample of graduate students for more than three years (Joumady and Ris, 2005). Year period was chosen primarily because it is a time of substantial change in public finance in the UK. This study noted a significant increase in technical efficiency, especially between the years 1987-1988 and 1990-1991. Inputs used in the analysis come from the number of lecturers and university tuition fees and the output are based on graduation rates and the number of doctoral theses.The findings suggest the average efficiency index between 55.3% and 67.8%. The results showed the homogeneity of performance for the university system as a whole. 2.1.2. Data Envelopment Analysis Data Envelopment Analysis (DEA) is a non-parameter approach for evaluating the performance of a set of homogeneous entities called Decision Making Units (DMU) where there are many inputs and outputs, each of which has different weight(weighted multiple inputs and weighted multiple outputs). This method was first discovered by Charnes, Cooper and Rhodes (CCR) (Charnes et al., 1978) with the aim to maximize the efficiency of the DMU is assessed from some set of entities. The term decision making units can be used to represent non-profit institutions such as schools, hospitals, government. The output of the institution will usually be difficult to quantify the value of money. In this study, the DMU ill represent the university. The weight of each input and output is highly variable whose value is determined from the significance of the inputs and outputs of the DMU. DMU will have a value of 100% efficiency when it is in the most forward position. Comparative efficiency value will be given by the following conclusions and DEA efficiency score of each DMU. Efficiency assessment factors are influenced by the amount of input and output variables. The calculation of the efficiency of universities largely apply methods Data Envelopment Analysis (DEA)(Ahn et al., 1988). III. METHODS 3.1. Research Design This research is carried out in three stages. The first stage is the development of efficiencyassessment model, the second stage is the evaluation of the efficiency by using the software, and the third stage is the implementation of efficiency assessment model in 12 universities education in Indonesia. This study will focus on the efficiency analysis of the university education in Indonesia by using DEA method. 3.2 Samples 12 public universities Education in Indonesia was used in this study, including six universities in Jawa (The most developed part in Indonesia) and six universities in other island (less developed). The universities are namely : UPI Bandung , UNJ Jakarta , UNNES Semarang , Surabaya UNESA , UNY Yogyakarta , Malang and six other from outside Java, which are UNP Padang , UNM Makassar, UnimedMedan , Manado State University, UndhiksaSingaraja and UNG Gorontalo . 3.3 Data Collection Procedures The data was collected by using the instruments available on the Internet and the primary data from the Higher Education institutions, the following table 1 shows the number of variables, the category boundaries of these indicators, as well as the tool being used to measure the indicator. The process of data retrieval from the web is using some of the official sites owned by the Higher Education and the Ministry of Education and also Google Scholar. Some output variables are also obtained through the Google search engine to obtain the number of papers and journals that are published for each university with regard to productivity of academia. In Table 1 explains the variables, types of variables, constraints and tools to collect data. Table 1.

Fourth of linear equations required for each unit of production ( total production from each of the university's research ) . IV. RESULTS DEA uses the ratio of total factor productivity to measure the performance (a single ratio with all inputs and outputs). DEA gives weight to each input and output variables. Each entity of the DMU is measured by using a linear optimization process that tries to get the maximum value of the ratio of each entity by finding the best weight value for each entity. The data were obtained by using a page of information provided by the Higher Education: http://pdpt.dikti.go.id, http://ban-pt.kemdiknas.go.id, and http://scholar.google.com. Table 2 below are the data that were obtained from official sources about the input and output variables needed in the assessment of the efficiency of a university. Table 2 .

Figure 1 is the initial view of the OSDEA software. Figure 1 . Open Source DEA ( OSDEA ) The fourth variable are the basis for the calculations, and those are the number of professors, the number of active students (undergraduate and graduate students) as the input and the number of publications produced by academician on the internet and a percentage of the accredited study program in the university as the output. The calculation of the university efficiency is approach by implementing CCR method the main model. Figure 2 shows the calculation process to the data for 12 universities by DEA method. Figure 2 . Process with the DEA calculation OSDEA All universities that do not have the level 1 of efficiency should strive to be efficient in a way : reducing inputs while maintaining a constant output (this is an input-oriented approach), increase output while maintaining a constant input ( this is an output-oriented approach, or a third model which seeks to reduce input and increase output.

Sixth place is occupied by Surabaya State University and the seventh to twelfth occupied by the University Education outside of Java, it shows the average efficiency University Education in Java is still better than the average efficiency University Education outside Java . IV . CONCLUSION The calculation of the efficiency of a university is strongly influenced by the ratio of output and input. The more output are generated by using the available input will improve the efficiency of the university.Calculation of the efficiency shows that the efficiency of the University Education in Java is generally better than the University Education outside Java.
