Abstract

On October 8th, 2016, it was inaugurated a simulator laboratory of STSTC (Scientific and Technical Simulator Training Center) owned by AMY (Yogyakarta Maritime Academy). The problem of the acceptance and satisfaction level of Nautical cadets to the simulator laboratory as the main learning media can be observed by a study based on Technology Acceptance Model (TAM). Research conducted to get the core problems that caused lack of motivation and satisfaction of Nautical cadets to the existing simulator laboratory. Items for measuring usefulness and ease of use are taken from Davis F.D (1989). Items for measuring user satisfaction are taken from Doll and Torkzadeh (1988). All these variables are measured by Likert scale. The results show that generally the acceptance of Nauticalcadets to the STSTC laboratory simulator especially the simulator bridge is good enough, but could not reach the maximum score caused by relatively low score on the satisfaction value.

Abstract

Penelitian ini bertujuan untuk menguji pengaruh pendekatan Realistic Mathematics Education bidang teknika pelayaran terhadap minat belajar taruna. Penelitian ini dilaksanakan di Jurusan Teknika, Akademi Maritim Yogyakarta. Subjek penelitian ini adalah Taruna semester I Tahun Akademik 2018/2019 dengan jumlah peserta didik sebanyak 43 orang yang mengambil mata kuliah Matematika Terapan. Jenis penelitian merupakan penelitian true experiment design dengan melibatkan satu kelas eksperimen dan satu kelas kontrol, desain pre-testpost-test control group design. Instrumen penelitian yang digunakan dalam penelitian ini terdiri atas instrumen lembar observasi dan instrumen kuesioner. Data di analisis secara deskriptif. Hasil analisis data menunjukkan bahwa pelaksanaan pendekatan Realistic Mathematics Education sangat berpengaruh untuk meningkatkan minat belajar taruna. Selain itu taruna memiliki respon yang sangat positif terhadap pembelajaran Matematika Terapan dengan menggunakan pendekatan Realistic Mathematics Education.

Abstract

Security is the most important part of computer network technology systems. Among the technologies that utilize networks are cloud computing. One cloud computing provider such as eucalyptus uses a firewall for system security. The use of a firewall on the system cannot monitor and analyze traffic that is inside the cloud server and does not give a warning when an attack occurs. The purpose of this study is that researchers will implement a network intrusion detection system (NIDS) in cloud computing and mirroring traffic on switches. Intrusion detection system (IDS) is a security technology that can analyze network traffic and detect traffic if an attack is indicated. NIDS are placed hosted differently from cloud computing servers. With the switch mirroring traffic method, traffic will be directed to NIDS so that NIDS can record all network traffic originating from outside the cloud server or traffic between virtual machines within the cloud server. The test results of attacks with 2 scenarios, namely attacks from outside and from within the cloud system, then NIDS is able to provide an alert response to traffic attacks.
