Integrating Technology in the learning process is very important in today’s digital era so that educators do not only have a component of content and pedagogical knowledge but also be have to be supported by the ability to integrate both components with technology. The purpose of this study was to analyze the competence of Technology, Pedagogy, and Content Knowledge (TPACK) of Education technology alumni in supporting their profession to become professional teachers. The method applied in this study was a Mixed method, using data from alumni who graduated in 2016-2017 through questionnaires and in-depth interviews. The results showed that the variables in TPACK, content knowledge variable and pedagogy content knowledge variable had a high average compared to other variables, namely 73.50 and 73.10. This indicated that from the pedagogic and content side, Education Technology alumni had a good mastery of content and pedagogical knowledge. However, being viewed from the average score in applying technology, their competence was still low. The Technology Pedagogy Knowledge variable achieved 48.30, while the TPACK variable reached 52.40. These results implies that Education Technology alumni still need to improve their TPACK competence in order to become a professional teacher in the era of industrial revolution 4.0.

Balinese script writing, as one of Balinese cultural richness, is going to extinct because of its decreasing use. This research is a way to preserve it through collaboration between Computer Science and Language discipline, that focused on accuracy comparison of Latin-to-Balinese script transliteration method on mobile application as a ubiquitous learning media. From few research in this area, there are only two existing methods to be compared, i.e. each on Android mobile application that were called Belajar Aksara Bali (BAB), and Transliterasi Aksara Bali (TAB). The comparison was based on The Balinese Alphabet writing rules and examples document by Sudewa. Through the experiment, TAB has outperformed BAB since TAB has passed over 68% (103 of 151) cases, while BAB has passed over only 39% (59 of 151) cases. This research contributes on a comprehensive accuracy comparison analysis of Latin-to-Balinese script transliteration method, specifically on mobile application, since there is no such study. This research also contributes on those methods improvement possibility. In the future, this research can be used as a reference for improvement of any Latin-to-Balinese script transliteration method by taking care on thirteen kind of special words that were found during this comparison study.

This research was conducted to evaluate POTWIS application by highlighting three usability concepts that effectiveness, efficiency, and the satisfaction of the user in using POTWIS application measured by usability testing methode, Performance Measurement, RTA, UEQ, and SUS technique. The purpose is to know the result of usability testing and improvement recommendation on POTWIS application based of the result of usability testing.The result of this research is based on analysis of statical calculation Mann Whitney U Test, UEQ dan SUS which showed (1) POTWIS application is not effective seen from the existance of the mistake made by respondent during the task, (2) POTWIS application is efficient seen from the time of task execution because the execution time between proficient group and beginner group was not significantly different, (3) POTWIS application has not met the scale of efficiency measured by UEQ with score 0.625 which showed below the average and (4) POTWIS application has not fulfilled user satisfaction measured by SUS with score 53.00 which is stated still below the average score is > 68.

AbstrakTujuan dari penelitian ini adalah memanfaatkan produk yang dihasilkan melalui pengujian secara eksperimen, untuk mengetahui efektifitas produk terhadap tingkat penguasaan konsep mahasiswa jurusan Pendidikan Teknik Informatika Undiksha. Rancangan penelitian yang digunakan adalah quasi eksperimen menggunakan desain post test dengan kelompok eksperimen dan kontrol yang tidak diacak. Hasil penelitian diperoleh bahwa respon mahasiswa terhadap penggunaan sistem simulasi binary tree berbasis CAI dalam perkuliahan matematika diskrit adalah positif dan Motivasi belajar mahasiswa masuk dalam kategori tinggi. Pengujian rumusan hipotesis yang dilakukan dengan uji t (student) diperoleh hasil bahwa t erdapat perbedaan yang signifikan antara hasil belajar mahasiswa yang dibelajarkan menggunakan Media Simulasi binary tree berbasis CAI dengan mahasiswa yang dibelajarkan tanpa menggunakan Media Simulasi binary tree berbasis CAI. Hal ini menunjukkan bahwa simulasi binary tree berbasis CAI merupakan media yang efektif digunakan untuk meningkatkan penguasaan konsep mahasiswa dalam perkuliahan matematika diskrit di jurusan Pendidikan Teknik Informatika Undiksha Singaraja. Kata-kata kunci : Simulasi Binary tree berbasis CAI, Pembelajaran Matematika diskrit, respon, hasil belajar, motivasi.Abstract The purpose of this study was to use the products produced through experimental testing, to determine the effectiveness of the product of the level of mastery of concepts students majoring in Information Technology Education Undiksha. The design of the study is a quasi experimental design using post test with experimental and control groups were not randomized. The result showed that the response of students to the use of binary tree based system simulation CAI in discrete math course was positively and student learning motivation in the high category. Formulation of hypothesis testing performed by t test (student) result that there are significant differences between the learning outcomes of students who learn to use the Media Simulation-based binary tree CAI with students studying without using Media Simulation-based binary tree CAI. This shows that the simulation-based CAI binary tree is an effective medium used to improve student mastery of concepts in discrete mathematics lectures in the Department of Informatics Engineering Education Undiksha Singaraja.
