Abstract

Media storage based on cloud computing is now widely used as a solution for exchanging data and information in an institution to support work. At STMIK PPKIA Tarakanita Rahmawati, cloud-based storage is very necessary because many data and information exchange activities are carried out digitally, both data exchange between lecturers, academic community, education staff and students. Utilization of ownCloud as an open source software to solve the problem of cloud computing-based data exchange is very appropriate because the website-based, desktop and mobile-based applications make it easier for users to access data.  Owncloud is similar to applications like Google Drive, Dropbox, it's just that all settings and data processing and user can be done independently so that it can adjust to the needs. The results of this research, Owncloud can be used well by lecturers to store data related to lectures and research, students to store lecture data centrally, the academic community in storing data related to academic activities. The design of owncloud is also still done intranet, so to access it must be connected to the network around the campus of STMIK PPKIA Tarakanita Rahmawati

Abstract

Data survei kepuasan pengguna lulusan merupakan salah satu cara yang dilakukan perguruan tinggi untuk menilai kualitas institusi ditinjau dari aspek kepuasan pengguna lulusan. Data tersebut sering mengandung nilai atribut yang hilang (missing value), yang dapat terjadi karena beberapa alasan, terutama ketika aspek yang dinilai tidak relevan dengan bidang pekerjaan lulusan. Penelitian ini menggunakan data survei kepuasan pengguna lulusan dengan jumlah 100 record dan proporsi missing value sebesar 20 persen pada atribut numerik. Evaluasi kinerja dilakukan menggunakan metode Root Mean Square Error (RMSE) dan Mean Absolute Percentage Error (MAPE) untuk membandingkan empat teknik imputasi missing value pada RapidMiner, yaitu penggantian dengan nilai rata-rata, nilai minimum, nilai maksimum, dan nilai nol. Hasil pengukuran menunjukkan bahwa model nilai rata-rata memperoleh kinerja terbaik dengan nilai RMSE sebesar 0,742 dan MAPE sebesar 13,67 persen. Sementara itu, tiga model lainnya berada pada nilai error lebih dari 1 pada RMSE dan lebih dari 20 persen pada MAPE. Pada model penggantian nilai nol, nilai error MAPE bahkan mencapai 100 persen, sehingga metode ini sangat tidak disarankan.
