Abstract

Cryptography can be used in prevent data, one of the preventive measures is by encoding messages. Cryptography is the study of encoding messages or ways of data protection. In encoding the content of messages, there is an algorithm conventionally used nowadays, the RSA (Rivest-Shamir-Adleman) algorithm. The RSA algorithm is a method that has two different keys for each encryption and decryption process but is still interrelated to maintain security in processing the data. In finding the key, the RSA algorithm utilizes the rule of prime number. The larger the prime number used as a key, the harder it is to find a large number as a factor. This research describes the process of encrypting text messages, the content of documents using the RSA algorithm, and the key generation process. Those processes are done by converting plaintext into ciphertext using ASCII code, which is 256 long, and using PKCS (Public Key Cryptography Standards) is the encryption process on the RSA algorithm. This study uses Pyhton programming language to implement the RSA algorithm on text messages and documents. As a recommendation to the subsequent studies, it is proper to use algorithms or other programming languages to secure messages.

Abstract

Penelitian ini bertujuan untuk meningkatkan minat dan pemahaman konsep trigonometri pada siswa kelas X-4 SMAN Model Terpadu Madani Palu melalui penelitian tindakan kelas. Penelitian dilaksanakan dalam dua siklus, yang masing-masing mencakup tahapan perencanaan, pelaksanaan, observasi, dan refleksi. Media pembelajaran berupa video dan platform interaktif Kahoot diintegrasikan ke dalam proses belajar mengajar untuk membuat pembelajaran lebih menarik dan interaktif. Data dikumpulkan melalui observasi, tes hasil belajar, serta angket respon siswa. Hasil penelitian menunjukkan adanya peningkatan signifikan pada nilai rata-rata siswa, khususnya pada siklus kedua dibandingkan dengan siklus pertama. Selain itu, partisipasi aktif siswa dalam pembelajaran meningkat secara substansial. Berdasarkan analisis angket, mayoritas siswa menyatakan bahwa penggunaan media pembelajaran ini membuat mereka lebih tertarik dan termotivasi dalam mempelajari trigonometri. Hasil penelitian ini menunjukkan bahwa kombinasi video dan Kahoot tidak hanya membantu siswa memahami konsep dengan lebih baik, tetapi juga menciptakan suasana pembelajaran yang menyenangkan dan interaktif. Strategi ini dapat menjadi alternatif yang efektif dalam meningkatkan kualitas pembelajaran matematika, khususnya pada materi trigonometri, dan mendorong partisipasi siswa secara aktif dalam proses pembelajaran

Abstract

In the era of sustainable development, education is a fundamental right for everyone. Education is a process of helping humans develop themselves so that they can face all problems with an open attitude. One way to help students clarify the concepts and understanding of mathematics that is being studied during the learning process is by using teaching aids. Teaching aids serve to facilitate the purpose of implementing learning in schools. However, the fact is that the use of mathematics teaching aids during learning at school is not yet entrenched, especially in areas far from urban areas, many of which do not have teaching aids. This directly impacts students' lack of understanding and learning experience, resulting in low student learning outcomes. This paper will introduce ALGATIKA, an application of lending mathematics teaching aids for elementary and junior high schools which can later solve these problems. The research methodology used is a qualitative descriptive method by deepening the material through literature studies. The result is that the lack of teaching aids in some schools can be overcome by the ALGATIKA application of lending mathematics teaching aids in elementary and junior high schools. Thus this application can help provide the teaching aids needed to build and improve educational facilities and provide an effective learning environment for all. It can develop students' teaching and learning processes and create higher quality education which leads to relevant and effective learning outcomes in accordance with the targets of the SDG's in education.
