Abstract

The online learning process currently utilizes a Learning Management System, one of which is Moodle. Moodle provides a forum menu where the forum is a digital forum for asking questions and answering and sharing between lecturers and students. Lecturer and student activity can be seen from the forum menu. For this reason, research was conducted on the ranking of lecturer activities in the moodle forum. The ranking determination uses the Fuzzy Tsukamoto decision making system. Fuzzy Tsukamoto has step efficiency in determining rules and processing data that has a taboo range and produces crips output. The processing steps carried out are determining the variables, giving weights, creating a fuzzy set of each variable, then the fuzzification process and creating a rule base and finally, defuzzification, namely the calculation of negligence and output. Based on the rule and the predicate alpha value, the appropriate value is obtained to rank the quality of lecturers based on their activities in the moodle forum. Keywords — database, forum, fuzzy, moodle, tsukamoto

Abstract

Social media in this digital era, especially Twitter, has an important role in the interaction between government and society. Given the wide variety of activities within government circles, the task of monitoring and responding to messages is complex and time-consuming. Therefore, this study aims to develop an effective approach in determining the appropriate response from the government to people's tweets. This study proposes using a combination of the Rabin-Karp method to quickly determine relevant responses. The Rabin-Karp method, known for its efficiency in pattern matching, is used to match tweets to a set of tweets that have already been given a response. Furthermore, the Word2Vec technique is used to improve understanding of the meaning of the text. The use of the Rabin-Karp method with the addition of the Word2Vec method shows that the response accuracy rate is 74.55%. The results of this study also show that the lower the K-Gram value, the higher the similarity value, and vice versa. These results are expected to contribute in the context of government that is responsive to societal issues discussed on Twitter.

Abstract

Information systems are very important in today's technological era. The services or methods used to deliver information are always evolving to provide better services. SIMAK-NG Udayana University is an information system built by the Udayana University Resources and Information Unit (USDI) to provide convenience to users (academic operators, lecturers and students) in online academic administration activities, which is Integrated Information System, known as Integrated Management Information System the Strategic of Udayana (IMISSU). Previously built on a monolithic architecture, SIMAK-NG migrate the service architecture to microservices. Therefore, need to customize the program code by implementing a RESTful API that supports the performance of SIMAK-NG service. In this study, the design of a RESTful API model was made This can be used by other applications that require student data from the SIMAK service and access RESTful API services instead of accessing the database directly. API was built using the Java programming language, the Quarkus framework, and a database schema that matched the database at the SIMAK-NG service at Udayana University. The test was run locally and show that the RESTful API program's response results are as designed and work well as shown in the tests using the Postman script. this indicates that the designed API program is ready for implementation.

Abstract

Algoritma Gortzel yang diturunkan dari DFT (Discrete Fourier Transform), dapat digunakan untuk mendeteksi frekuensi dengan bantuan processor DSP TMS320C31. Algoritma Gortzel mendeteksi frekuensi dengan tingkat keberhasilan pendeteksian sangat tergantung pada jumlah cuplikan (N), semakin banyak jumlah cuplikan makasemakin akurat pendeteksian frekuensi tersebut. Akan tetapi semakin banyak jumlah N, maka proses iterasinya menjadi lebih kompleks, sehingga waktu yang diperlukan untuk melakukan pendeteksian semakin lama. Untuk itu perlu dipilih jumlah N yang digunakan agar waktu yang diperlukan sesingkat mungkin.
