Abstract

Sistem Informasi Universitas Klabat (SIU) adalah sistem informasi sekolah yang digunakan oleh mahasiswa, dosen dan staff dalam mengatur jadwal, presensi, nilai dan administrasi lainnya. Dengan rata-rata lebih dari 700 hits perhari, SIU menjadi sistem yang sangat krusial dalam menopang kegiatan belajar mengajar sehingga diperlukan sebuah evaluasi sistem yang terukur. Penelitian ini bertujuan untuk mengetahui penerimaan pengguna SIU menggunakan Technology Acceptance Model (TAM). Pengguna di sini adalah 10% dari total mahasiswa tingkat 1. Penelitian ini adalah penelitian kuantitatif dengan metode penelitian studi kasus. Variabel dalam penelitian ini terdiri dari dua variabel bebas yaitu kemanfaatan (perceived usefulness), dan kemudahan (perceived ease of use) serta variabel terkait yaitu penerimaan pengguna (user acceptance). Untuk mengakomodasi variable indepent yang lebih dari satu analisis data yang digunakan adalah regresi berganda dan uji hipotesis. Dari 80 sampel responden yang diambil dari 800 freshmen empat fakultas berbeda, didapat bahwa penggunaan SIU sudah baik karena diterima oleh penggunanya dengan hasil persepsi kemanfaatan sebesar 0,166 dan hasil persepsi kemudahan 0,498. Diketahui juga bahwa penerimaan pengguna dapat dipengaruhi oleh persepsi kegunaan dan persepsi kemudahan.

Abstract

Fear or anxiety about a particular situation or object is called phobia, one of the phobias that exists today is Claustrophobia which is a phobia of a closed or small room. The current Claustrophobia therapy method is still traditional, namely by placing the patient in a place that will trigger the patient’s Claustrophobia. This study aims to produce a therapeutic aid and diagnosis of Claustrophobia with Virtual Reality Exposure Therapy method that uses Android-based Virtual Reality and Photogrammetry technology that can be used by medical experts or therapist when conducting therapy to Claustrophobia patients. The research method used is prototyping model. The way to collect data that will be used is by interview and application testing. Researchers used the Unity3D Engine software to create Virtual Reality application and Agisoft Metashape software to create Photogrammetry objects. The application is expected to facilitate the Claustrophobia patients and help people to predict the level of Claustrophobia suffered. The app produced on this research was able to produce the expected virtual environment and had a limited test to user and had similar reaction to a real room. For future research additional rooms and exploration mode may be added, as well as further evaluation to see how this application can be used for therapy tools.

Abstract

In learning projectile motion and its velocity, students tend to look up a plain two-dimensional image in a science book. While there’s some educational props, yet they usually a very tradional ones and can not be used for real calculation. The utilization of Augmented Reality (AR) in educational method may raise curiosity and gives a unique way in learning projectile motion as the motion can be seen in a three dimensional. Augmented Reality itself is a combination of real world and virtual objects. This application uses the Vuforia SDK that able to blend the real world and virtual objects. Through this application, we were able to simulate projectile motion and its velocity in more realistic way, have slightly interaction with the reality, and gets input from user so they can learn and see the result of the parameter that they entered. Thus, with the advantage of AR the application gives a more realistic feel compared to the existing ones available in public as it could receive any input and show the output in AR.

Abstract

School lessons can be uninteresting and even dull. Subjects like maths, physics or chemistry are on top of the list, and one topic that often hard to grasp is the projectile motion lesson. Gamification is seen as one of the concepts where learning can be much more engaging. Using Unity 3D, we were able to develop gamification of the projectile motion lesson. By transforming it into an Angry Birds look alike, the learning process is experienced in this turn-based game become much more enjoyable. Instead of pointing where to shoot, students are asked to calculate the velocity by taking the given value such as angle and distance. The game can be played alone, as in practice mode, or two players as in versus mode or even two groups which is very applicable in a class (i.e. Group 1 vs Group 2) and since it uses real physics equation, the application able to show a realistic simulation of the projectile motion path. School lessons can be uninteresting and even dull.

Abstract

We have been always trying to predict the weather to minimize risk, produce strategy, and other decision making situation. To achieve this, monitoring method need to be used to gather data. Rainfall monitoring is one of the area that widely used and one of the mostly used method is satellite-based rainfall monitoring. However, there are limitation to apply to the Satellite Rainfall (SR) estimation specifically on its accuracy and lack of certainty. Thus, study that directed to measure the inaccuracies of SR measurements is needed by using data of distribution of Actual Rainfall (AR). The SR data is taken from the National Oceanic and Atmospheric Administration (NOAA)’s Hydro—Estimator while the AR data was from the National Institute of Water and Atmospheric Research (NIWA). Through the statistics and interpolation analysis using ArcGIS, the study shows a prominent result of SR estimation accuracy in the sample area and thus may opens up more similar implementation as well as stands as a good benchmark for future improvement of the method. This study also shows how interpolation method through a GIS software could provide a significant result on a geographical related studies. Keywords : GIS, Geospatial Analysis, Interpolation Analysis, Arcgis
