Abstract

Pola simetri p2mm adalah wallpaper group yang mempunyai simetri rotasi , refleksi terhadap sumbu-x dan sumbu-y, dan translasi terhadap sumbu-x dan sumbu-y. Dalam artikel ini, pola simetri p2mm berwarna dibangkitkan melalui sebuah simulasi sistem dinamik diskrit menggunakan aplikasi Matlab, dengan terlebih dahulu melakukan analisis terhadap syarat dan pemilihan pada fungsi dinamiknya. Dalam pembangkitan pola p2mm ini, setiap titik pada bidang dijadikan sebagai titik awal pada iterasi sistem dinamik diskrit, dan jumlah iterasi yang dihasilkan menentukan warna pada titik tersebut. Dengan menggunakan beberapa kombinasi nilai-nilai parameter pada fungsi dinamik, diperoleh variasi pola-pola p2mm yang menarik dan estetis.

Abstract

Pola simetri p2 adalah pola simetri yang memenuhi simetri rotasi 180^o dan simetri translasi di sepanjang sumbu-x dan sumbu-y dengan periode tertentu. Dalam makalah ini akan dibahas pembangkitan pola simetri p2 dari simulasi sistem dinamik dengan menggunakan aplikasi Matlab. Dalam hal ini dilakukan terlebih dahulu analisis terhadap syarat dan pemilihan pada fungsi dinamik yang memenuhi sifat-sifat pada pola simetri p2. Dalam proses pembangkitannya pada Matlab, setiap titik pada suatu bidang dijadikan sebagai titik awal pada iterasi sistem dinamik, kemudian warna yang diberikan pada titik tersebut ditentukan dari jumlah iterasi yang dihasilkan melalui kriteria konvergensi Euclidean. Berdasarkan simulasi terhadap beberapa kombinasi nilai-nilai parameter pada fungsi-fungsi dinamik, dihasilkan pola-pola simetri p2 yang lebih variatif.

Abstract

This research discusses the SISiR model (Susceptible Infected Sick Recovered) considering individual immune parameters and lockdown parameters. The consideration of these parameters aims to determine whether immunity and lockdown have an impact on the spread of COVID-19. The model's stability is analyzed around the equilibrium point to understand the dynamics of COVID-19 spread in a population. Furthermore, the parameter R0 is determined to indicate whether COVID-19 disappears or remains in the population. From numerical simulations with spesific parameter values, it is concluded that COVID-19 continues to spread in the population with an R0 = of 4.4486. The addition and reduction of immune and lockdown parameters affect the spread of COVID-19.

Abstract

The Quran is the source of all knowledge, including mathematics. On the other hand, mathematics is closely related to everyday life and the development of other fields of knowledge. Mathematics is one of the disciplines closely connected to the verses of the Quran. Mathematics education is expected to improve to meet the advancements in time and technology continually. It is also anticipated that mathematics education can build the character of each student through religious values. This activity aims to introduce the concept of sets integrated with the content of verses found in the Quran. The activity was conducted as an online Zoom meeting and YouTube streaming seminar. Participants included mathematics lecturers, teachers, and students from Islamic junior and senior high schools from ten provinces in Indonesia. The event was titled "The Quran and Set Theory" and received high appreciation from the seminar participants. This was evident from the enthusiastic participation and numerous questions raised during the Q&A session. This activity has motivated teachers and lecturers to integrate the mathematical concepts learned with the Quranic verses. Teachers who participated in this activity are expected to act as agents in popularizing the method of integrated mathematics education with the content of Quranic verses, especially set theory.
