The development of higher education is very rapid rise to the tight competition both public universities and private colleges. XYZ University realized to win the competition, required continuous quality improvement, including the quality of existing service facilities. Amenities quality services is believed to support the success of the learning activities and improve user satisfaction. This study aims to determine the extent to which the quality of the services effect on user satisfaction. The research method used is survey-based questionnaire that measure perception and expectation. The results showed a gap between perception and expectations of the respondents have a negative value for each item. This means XYZ service facility at the university is not currently meet the expectations of society members. Three service facility that has the lowest index is based on the perception of respondents is a laboratory (2.56), computer and multimedia (2.63) as well as wifi network (2.99). The magnitude of the correlation between satisfaction with the quality of service facilities is 0.725 which means a strong and positive relationship. The influence of the quality of service facilities to the satisfaction of the students is 0.525 meaning that the variable quality of the services facility can explain 52.5% of the variable satisfaction. The study provided recommendations for improvements to enhance the quality of services facility at the XYZ university facilities.

The aim this study is discussed on the detection and correction of data containing the additive outlier (AO) on the model ARIMA (p, d, q). The process of detection and correction of data using an iterative procedure popularized by Box, Jenkins, and Reinsel (1994). By using this method we obtained an ARIMA models were fit to the data containing AO, this model is added to the original model of ARIMA coefficients obtained from the iteration process using regression methods. In the simulation data is obtained that the data contained AO initial models are ARIMA (2,0,0) with MSE = 36,780, after the detection and correction of data obtained by the iteration of the model ARIMA (2,0,0) with the coefficients obtained from the regression       1 2 1 2 3 0,106 0, 204 0, 401 329 115 35,9 t t t Z Z Z X t X t X t         and MSE = 19,365. This shows that there is an improvement of forecasting error rate data.

Globalization does not only involve the spread of massive information technology throughout the world. In the early 2020s the world also experienced a global pandemic COVID-19 which plagues almost all countries in the world. COVID-19 forces learning activities di higher education level to be carried out with social distancing concepts. Online learning can be done using a number of popular information technology applications. The study involved college students from the faculty of computer science and engineering. They took courses on enterprise resource planning, human-computer interaction, and research methods. The results showed that COVID-19 did not impede learning activities. A number of social technologies such as Dropbox, Facebook, Google Forms, Moodle, WhatsApp, WordPress, YouTube, and Zoom have seen a surge in usage to support distance learning activities during the COVID-19 pandemic. With online distance learning mode, all learning activities can be done with the concept of work from home.

Presence is one of the important factors in the university because students' attendance can support learning activities, especially at Bina Darma University. Problems that occur at this moment are in the data present student data, where the persistent system still using paper media (paperbased

Information technology (IT) has been used widely in many aspects of our daily life. Social media as a leading application on the internet has changed many aspects of life become more globalized. This article discussed the use of social media to support learning activities for students in the faculty of computer science. The author used Facebook and WordPress as an alternative to electronic learning, those were: 1) online attendance tool, 2) media storage and dissemination of course materials, 3) and event scheduling for the lectures. Social media succeed to change the way of modern learning styles and environment. The results of this study are some learning activities such as (1) Preparation, (2) Weekly meeting activities, (3) Course
