-The new paradigm of higher education requires higher education institutions (HEIs) to be managed by utilizing information technology (IT). This has been recognized by the HEIs, but it did not go smoothly. Frequently occur in development process, the re-creation of the necessary facilities (low sustainability). This article discusses the cause identification of low IT sustainability in HEIs and proposes solution that is Service Oriented Architecture (SOA) concept. The identification process is done by means of literatures review and observation followed by process of analysis utilizing root cause analysis and worst case analysis, with fishbone diagrams and checklist as instruments. It concluded that the root cause of low IT sustainability is the approach or development method that cannot adapt to changes and does not consider collaborations. The exploiting of SOA concept is suitable to solve the problem based on the worst case analysis. Thus, IT-based systems in HEIs will be sustain.

Feedback Information System Teaching and Learning Against Web-Based Teaching Staff In the Department of Information Technology Padang State Polytechnic is an information system that receives feedback from the learning process of students to teaching staff in the form of questionnaires, to then process and provide the necessary information. This system can be accessed by many users at the same time. Users of this system consists of students, operators, administrator, and faculty leaders. The system is built using PHP programming language and MySQL database server. This system could make it easier, save time and reduce errors in entering, process and provide information on the results of data processing questionnaires. While limitations are only limited to faculty assessment only and limited to the processing of assessment ratio.

The resulting of system is a web based application executed, it can be accessed by many users at the same time trough each on computer from browser by accessing the specified address. The users of this system consists of a head, department chairman, the general secretary of the department and administration of department, this system is build using PHP programming language and MySql database server. Advantages of this system is that it can save paper (paperless) and storage physical space. On this system can monitor incoming mail, incoming mail was processed, outgoing mail and letters that have been in the disposition that is in Polytecnic with available in online then this system becomes more effective performance and efficiently

Department of Information Technology Padang State Polytechnic growing rapidly, the number of students and the amount of data will increase too. However, these conditions will bring complex problems to the department to manage it in quantitative and qualitative way.  How complicated the problems faced when there are a lot of data that needs to be processed, and if it goes wrong it needs a long time to find, fix and change it. To minimize the errors and redundancies in processing the data, the department requires an academic information system. This system will manage student grades, final assignment and job training data at Information Technology Department. This web based Academic Information System was develop by using object oriented concept and JAVA especially J2EE technology as programming language and MYSQL Server as database. This system also design by using UML(Unified Modeling Language).
