ABSTRACT This research is motivated by the several new regulations on publication obligations in international journals for lecturers, doctoral students and researchers. The focus of analysis in this paper is on UGM collaborations in publications in Scopus from 1954 to 2016, using bibliometrics and correlations. The findings show that international collaborations received more citations than any other collaborations and individual work. International collaboration received 22.431, with average of 11,8432. internal collaboration is 2.072; 1,9328. Domestic collaboration is 1.458, 1,4609. individual work is 1.014; 3,6344. The country's largest citation producer collaborator is Japan, some 5.242, with average of 12,31. Followed by USA 4.50; 26,49, then the Netherlands 4.057, 18, 69. Individual publications are not correlated with the citation obtained, while the publication of the collaborative works are all positively correlated. International collaboration is expected to have a perfect correlation of +1 by the end of the decade 2010-2019.

Such automation software is expected to be able to support the success of library services and to produce statistical information for a decision making. The research aims to find out the quality of Sipus V3 software and its statistical information output, and the use of the output for supporting decision making. The research describes the subjective quality of Sipus V3 software, its statistical information output, and the use of the output in decision making process. The research employs a questionnaire method to collect data and its respondents are 44 librarians involving in Sipus V3 and 26 persons working at the information management department responsible for the statistic output of Sipus V3. By using a mean method for each indicator value, the result of the research shows that the high indicator score of Sipus V3 software quality as follows: usability-operability 3,75; efficiency of resources 3,75; efficiency of time behavior 3,68; usability-understandability 3,64; functionality-suitability 3,55; maintainability-stability for the rules of lending period and the number of items borrowed 3,43; reliability-recoverability 3,30; and maintainability-stability for holiday/closing days 3,20. In contrast, the low indicator score can be seen in the following: functionality-accuracy 2,84; and reliability-maturity 2,68. Furthermore the indicator score of Sipus V3 statistical information which is high is timeliness 3,31; conciseness 3,23; relevancy 3,15; and completeness 3,15. Whereas the low indicator score is accuracy 2,92.

It uses Subramanyam formula to calculate the level of collaboration. The result shows that most of the articles in IJC are written through collaboration with the level of 0.82 and mean cf 3.05 writers per article. From the year of 2007 until 2011, it tends to show improvement on both collaboration and mean figures. The IJC has taken other institution's writer's interests since Gadjah Mada University has contributed only 21.35%. 75 local institutions share 59.06% while 52 foreign institutions share 40.94%.
