Abstract

This research was conducted as a learning alternatives for study of CT (computed tomograpghy) imaging using image reconstruction technique which are inversion matrix, back projection and filtered back projection. CT imaging can produce images of objects that do not overlap. Objects more easily distinguishable although given the relatively low contrast. The image is generated on CT imaging is the result of reconstruction of the original object. Matlab allows us to create and write imaging algorithms easily, easy to undersand and gives applied and exciting other imaging features. In this study, an example cross-sectional image recon-struction performed on the body of prostate tumors using. With these methods, medical prac-titioner (such as oncology clinician, radiographer and medical physicist) allows to simulate the reconstruction of CT images which almost resembles the actual CT visualization techniques.Keywords : computed tomography (CT), image reconstruction, Matlab

Abstract

ABSTRACTThis research discusess the physics of motion particulally contained in the mobile gameUltraflow so this game could be an alternative media that can help teachers to explainphysics of motion to students in an interesting way and not boring. This research studyphysics focused on physics of motion which are contained in part 1, 2, 3 and 6 of thegame and only one level that that had been chosen as representation of these parts.Level 7 had been selected as the representation of part 1, level 13 had been selectedas the representation of part 2, level 24 had been selected as the representation of part3 and level 40 had been selected as the representation of part 6. Eventually, thesechosen levels had been analyzed by evaluating the physics of motion contained intherein.Keywords: game, physics of motion, UltraflowABSTRAKPenelitian ini membahas materi fisika gerak secara khusus yang terkandung di dalammobile game Ultraflow sehingga game ini dapat menjadi alternatif mediapembelajaran yang dapat membantu pendidik untuk menjelaskan materi fisika gerakkepada peserta didik dengan cara yang menarik dan tidak membosankan. Padapenelitian ini kajian yang fisika akan dilakukan hanya difokuskan pada bagian 1, 2, 3dan 6 dan hanya memilih salah satu level yang dapat dianggap mewakili keempatbagian tersebut. Untuk bagian 1 dipilih level 7, untuk bagian 2 dipilih level 13, untukbagian 3 dipilih level 24 dan untuk bagian 6 dipilih level 40. Kemudian, selanjutnyatiap-tiap level yang telah dipilih tersebut dianalisis dengan melakukan kajian-kajianfisika gerak yang terkandung di dalamnya.Kata kunci: game, fisika gerak, Ultraflow

Abstract

ABSTRAk Generasi milenial yang sebagian besar merupakan pelajar SMP dan SMA lebih banyak menghabiskan waktunya dengan gadget. Banyak pelajar masa kini sulit memahami pelajaran yang dipelajari di sekolah sehingga sampai di rumah mereka kembali sibuk dengan gadget-nya masing-masing dan melupakan topik pelajaran yang telah dipelajari di sekolah. Oleh karena itu, kebanyakan orangtua menyadari hal tersebut sehingga memberikan pelajaran tambahan bagi anak-anaknya dengan mendaftarkan anak-anaknya ke lembaga-lembaga bimbingan belajar (bimbel) terkenal ataupun mencari guru-guru les privat. Dengan semakin berkembangnya m-learning, siswa tidak perlu lagi harus datang ke lokasi bimbel karena Mereka bisa belajar kapanpun mereka mau setiap mereka membawa laptop atau smartphone dengan mengakses bimbingan belajar online (bimbel online). Ruangguru hadir sebagai salah satu alternatif bimbel online yang dapat dengan mudah diakses melalui smartphone, laptop ataupun tablet. Beberapa fitur unggulan seperti RuangUji, Ruang Latihan, Ruang Video, RuangLes, RuangLesOnline, Digital Boot Camp dan Edumail memungkinkan siswa untuk meng-upgrade kemampuan belajarnya sehingga diharapkan dapat mencapai hasil yang diinginkan. Kata Kunci: m-learning, ruang guru. ABSTRACT Millennial generations, mostly junior and senior high school students are spending much more of their time with gadgets. Nowadays, many students find it hard to understand their school lessons then neglect them at home. Parents realize this problem then help their children by enrolling them in tutoring agencies or seeking private tutors. With the development of m-learning, students no longer need to come to the location of guidance because they can learn whenever they want each they bring a laptop or smartphone by accessing online tutoring. Ruangguru presents as one of alternative online tutoring media can be easily accessed via smartphone, laptop or tablet. Ruangguru provides some excellent features such as RuangUji, RuangLatihan, RuangVideo, RuangLes, RuangLesOnline, DigitalBootCamp dan Edumail allow students to upgrade their learning abilities so that they are expected to achieve the desired results. Key Words: m-learning, ruangguru.
