About

I'm an assistant lecturer at Hasanuddin University. 2 years ago, im completed my studies with a major in Mathematics, especially in signal analysis. My research is now focused on quaternion algebras and the solution of complex equations involving quaternions. My current research is on the Laplace equation, and I'm developing the classical Laplace transform for quaternions. My research will always be helpful for the future.

The Ortogonal Property of Directional short-time quaternion Fourier transform

Daya Matematis: Jurnal Inovasi Pendidikan Matematika · 2022

This study will examine the orthogonal properties of Directional Short-time quaternion Fourier transform (DSTQFT) which is a further study of DSTFT with an expansion in the form of a function that has a Quaternion value. The orthogonal properties of DSTQFT are obtained by combining the orthogonal properties of  DSTFT and the Fourier quaternion transform (QFT). Based on the results of the study, it was found that the orthogonal nature of the Directional Short-Time quaternion Fourier Transform (DSTQFT) is different from the orthogonal nature of the Directional Short-Time Fourier Transform (DSTFT). In addition, there are three important consequences of orthogonality in TFQSTB as a result of the quaternion-valued function.

Deskripsi Penggunaan Media E-Learning dalam Pembelajaran Matematika di Masa Pandemi Covid-19

Jambura Journal of Mathematics Education · 2021

Penelitian ini bertujuan untuk mendeskripsikan Penggunaan  media e-learning dalam pembelajaran matematika di masa pandemi (Covid-19). Penelitian ini adalah penelitian deskriptif  kuantitatif dengan populasi seluruh peserta didik kelas IX SMP N 4 Kota Gorontalo yang berjumlah 217 peserta didik. Sampel dalam penelitian sebanyak 22 orang. Teknik pengambilan sampel yaitu simple random sampling. Data penelitian diperoleh dari lembar pengamatan guru dan peserta didik terkait penggunaan media e-learning ( Zoom, Whatsapp, Google Classroom), tes hasil belajar angket respon peserta didik  serta wawancara guru dan peserta didik tentang penggunaan media  e-learning dalam pembelajaran matematika di masa pandemi. Hasil penelitian menunjukan bahwa penggunaan media e-learning dalam pembelajaran matematika di masa pandemi berada pada kategori kurang baik  yang ditunjukan dengan Kegiatan Guru memperoleh rata-rata presentase 54,4%, kegiatan Peserta didik memperoleh rata-rata 60%, respon peserta didik memperoleh rata-rata 73,6%, dan tes hasil belajar presentase peserta didik yang tuntas adalah 45.4% dan peserta didik yang tidak tuntas sebesar 54,5%.
