Abstract

The development of the education curriculum in Indonesia makes students must have skills so that they can compete globally, especially in the 21st century. The development is closely related to technology and information. One of skills that support the development of technology and information is the computational thinking skills. This study aims to analyze students’ computational thinking skills on the number patterns lesson during the Covid-19 pandemic. This study was qualitative-descriptive research with the subjects of 4 students from 8th grade in Makassar. The instruments used in this study were a test of the computational thinking skills in the form of essay type test on the number patterns lesson and interview guidance. The results of this study indicated that all subjects met the first indicator of problem decomposition and one subject met the second indicator of problem decomposition, all subjects met the indicator of pattern recognition, three subjects met the indicator of abstraction and generalization, all subjects met the first indicator of algorithmic thinking and two subjects met the second indicator of algorithmic thinking on computational thinking skills. Thus, students’ computational thinking skills during the Covid-19 pandemic were still low, so an educational framework is needed to improve students’ computational thinking skills.

Abstract

Teorema Residu memiliki penerapan yang menarik pada berbagai bidang matematika. Penerapan tersebut seperti pada evaluasi transformasi Fourier, transformasi Mellin dan penentuan nilai integral tak wajar yang melibatkan fungsi yang tergolong relatif rumit seperti pada integral Dirichlet dan integral Fresnel. Selain penerapan-penerapan tersebut dalam penentuan nilai eksak integral, teori residu juga mempunyai penerapan pada penentuan nilai eksak dari suatu deret tak hingga yang konvergen. Pada penelitian ini, diturunkan kemudian dibuktikan sebuah aturan untuk menentukan nilai eksak dari suatu deret tak hingga yang memenuhi syarat-syarat tertentu. Metode penelitian yang digunakan berupa kajian literatur. Peneliti mengumpulkan sumber-sumber ilmiah baik berupa artikel ilmiah maupun buku-buku yang kemudian dianalisis untuk mencapai tujuan penelitian. Hasil penelitian memberikan syarat cukup terkait dengan penggunaan rumus yang diperoleh, yaitu barisan  (sup{|f(z)|:z \in C_N}) yang merupakan barisan dengan indeks  konvergen dengan cepat ke nol serta  analitik kecuali untuk berhingga banyaknya pola. Dari hasil yang diperoleh tersebut, peneliti juga melakukan perhitungan mengenai nilai eksak dari fungsi zeta-riemann di bilangan genap positif sebagai salah satu aplikasi dari aturan tersebut.

Abstract

In this paper we investigate the boundedness of Mikhlin perators on generalized Morrey spaces. Theresults show that the operators are bounded on generalized Morrey spaces under some assumptions.
