Abstract

Penelitian ini bertujuan untuk mengetahui faktor yang memengaruhi penggunaan elearning.umn.ac.id pada mahasiswa melalui kerangka Technology Acceptance Model (TAM). Terdapat lima konstruk asli dari TAM yang digunakan dalam penelitian ini, antara lain persepsi kegunaan (PU), persepsi kemudahan penggunaan (PEOU), sikap terhadap penggunaan (ATU), minat perilaku (BI), dan penggunaan senyatanya (AU). Terdapat pula tiga konstruk eksternal yang digunakan dalam penelitian ini, antara lain keyakinan individu (SE), aksesibilitas sistem (SA), dan kualitas sistem (SQ). Hasil yang didapatkan pada penelitian ini menemukan tingkat penerimaan dan penggunaan e-learning UMN pada mahasiswa dengan menggunakan faktor internal (perceived usefulness, perceived ease of use, attitude toward using, behavioral intention, actual use) dan faktor eksternal (self-efficacy, system accessibility, system quality) TAM sudah tinggi. Perceived ease of use tidak memiliki hubungan apapun terhadap faktor-faktor yang lain, sehingga apabila faktor perceived ease of use ditingkatkan maka tidak akan terjadi pengaruh apapun terhadap actual use, meskipun didukung dengan faktor system accessibility. Adapun pengaruh positif signifikan yang dimiliki semua pasangan variabel memiliki sifat pengurangan nilai, sehingga jika sebuah faktor independen memiliki peningkatan skor sebanyak n, maka faktor dependen yang memiliki hubungan terhadap variabel independen tersebut ikut mengalami peningkatan skor namun mengalami penurunan nilai dengan besar n sejumlah dengan nilai koefisien total pengaruh yang dimilikinya.

Abstract

Students and scheduling are both essential parts in a higher educational institution. However, after schedules are arranged and students has agreed to them, there are some occasions that can occur beyond the control of the university or lecturer which require the courses to be cancelled and arranged for replacement course schedules. At Universitas Multimedia Nusantara, an agreement between lecturers and students manually every time to establish a replacement course. The agreement consists of a replacement date and time that will be registered to the division of BAAK UMN which then enter the new schedule to the system. In this study, Ant Colony Optimization algorithm is implemented for scheduling replacement courses to make it easier and less time consuming. The Ant Colony Optimization (ACO) algorithm is chosen because it is proven to be effective when implemented to many scheduling problems. Result shows that ACO could enhance the scheduling system in Universitas Multimedia Nusantara, which specifically tested on the Department of Informatics replacement course scheduling system. Furthermore, the newly built system has also been tested by several lecturers of Informatics UMN with a good level of perceived usefulness and perceived ease of use. Keywords—scheduling system, replacement course, Universitas Multimedia Nusantara, Ant Colony Optimization
