The impact felt by Indonesia in addition to the many positive cases, economic, social and educational system problems. The learning process that has been carried out face-to-face has become undisturbed, so that the learning process changes its function to online learning. The purpose of this research is to obtain information on how to describe the implementation process of learning for students of the Pamulang University Mathematics Study Program during the Covid-19 pandemic as an effort for Higher Education to stop and break the chain of spreading covid-19. The research subjects were students of the Mathematics Study Program. Data processing was carried out by interviewing through cloud meetings and questionnaire response sheets using the google format. Interviews and questionnaire sheets were conducted with questions that were compiled and developed with related literature. Miles & Huberman's interactive analysis techniques were used in this study. This study obtained the results, namely, (1) students already have basic learning facilities such as leptops, computers, android-based mobile phones and internet networks; (2) The learning process has not been maximally carried out yet; (3) Lack of supervision from both lecturers and parents during the lecture or learning process; (4) The online learning process has the advantage of flexibility in time, encourages and trains students to study independently. Keywords: Online learning, Learning Effectiveness, Covid-19 Pandemic. Abstract Penyebaran virus covid-19 secara global masih terus bertambah. Dampak yang dirasakan Indonesia selain banyaknya kasus positif, masalah ekonomi, sosial dan sistem pendidikan. Proses pembelajaran yang selama ini dilakukan secara tatap muka menjadi terganggu, sehingga proses pembelajaran berubah fungsi menjadi pembelajaran daring(online). Adapun penelitian ini memiliki tujuan untuk memperoleh informasi bagaimana gambaran proses pelaksanaan pembelajaran daring untuk mahasiswa Prodi Matematika Universitas Pamulang selama pandemi covid-19 sebagai upaya Perguruan Tinggi untuk menekan dan memutus rantai penyebaran covid-19. Subjek penelitian adalah mahasiswa Prodi Matematika. Proses pengumpulan data dilakukan dengan wawancara melalui zoom cloud meeting dan lembar angket respon menggunakan google format. Wawancara dan lembar angket dilakukan terstruktur dengan pertanyaan yang disusun serta dikembangkan dengan literatur terkait. Teknik analisis interaktik Miles & Huberman yang digunakan dalam penelitian ini. Penelitian ini memperoleh hasil yaitu, (1)Mahasiswa sudah mempunyai fasilitas-fasilitas dasar pembelajaran daring seperti, leptop, komputer, handphone berbasis android dan jaringan internet; (2) Proses pembelajaran daring yang dilakukan belum maksimal sepenuhnya; (3) Kurangnya pengawasan baik dari dosen dan orang tua saat proses perkuliahan atau pembelajaran; (4) Proses pembelajaran daring memiliki keuntungan perihal fleksibilitas waktu, mendorong dan melatih mahasiswa untuk belajar secara mandiri.
