The objectives of this study were to: (1) describe the perceptions of students in the Mathematics Study Program of the Faculty of Science and Technology, Purwokerto University of Nahdlatul Ulama (UNU) on learning interactions between students and students and students and lecturers; (2) describe the perceptions of students in the Mathematics Study Program of UNU Purwokerto about the learning environment in online learning. The subjects of this study were students in the 2nd and the 4th semester of the Mathematics Study Program of UNU Purwokerto. This research was conducted in April - June 2020. The data in this study were obtained from questionnaires and interviews. . The subjects in this study were taken by purposive sampling technique. The data validation used the triangulation method. Data analysis techniques used data reduction, data presentation, and drawing conclusions. The results showed the following: 1) students had difficulty in interacting with fellow students and lecturers in online lectures. This is evidenced by the high level of presentation which shows disagreement with the statement that says student interaction in online lectures has gone well; 2) students response to the learning environment in online lectures, it can be concluded that the learning environment in online lectures has not supported students to learn.

Tujuan dari kegiatan Pengabdian Kepada Masyarakat (PKM) ini adalah meningkatkan kemampuan guru dalam menyusun soal HOTS (Higher Order Thinking Skills) sesuai dengan kisi-kisi Ujian Nasional (UN) Matematika. Beberapa kesulitan yang dialami oleh bapak/ibu guru selama mengajarkan soal HOTS adalah kurangnya pemahaman terkait soal HOTS, membuat soal HOTS sesuai dengan indikator, dan kesulitan dalam mengajarkan ke siswa. Kegiatan PKM ini dalam bentuk workshop dimana dimulai dari penyampaian materi, sesi tanya jawab, dan penyusunan soal HOTS sesuai dengan level kognitif matematika. Dimana kegiatan ini bekerjasama dengan KKG Kecamatan Sumpiuh dengan peserta adalah bapak/ibu guru sebanyak 56 guru kelas 5 dan 6. Metode yang digunakan adalah Service Learning. Hasil dari kegiatan ini adalah dapat meningkatkan kopetensi guru dalam menyusun soal HOTS sesuai dengan level kognitif matematika ditunjukkan dari hasil penilaian bahwa (1) pada soal HOTS level pengetahuan dan pemahaman (L1) 64.3% masuk kriteria sangat baik; (2) pada soal HOTS level aplikasi (L2) 44.6% peserta masuk kriteria sangat baik; (3) pada soal HOTS level penalaran (L3) sebanyak 46.4% masuk dalam kriteria cukup.

The Covid-19 pandemic has caused the learning process to be hampered and cannot be carried out face-to-face. Therefore, a solution is needed for this problem. One alternative to overcome this problem is online learning. This study aims to describe the effectiveness of online learning using online media during the Covid-19 pandemic in Mathematics courses. The subjects of this study were 51 students in the Faculty of Science and Technology, Nahdlatul Ulama University, Purwokerto. They were from five different study programs, namely Agrotechnology, Mathematics, Biology, Fisheries Science, and Agricultural Biosystems Engineering, who had taken mathematics courses. This study was carried out in June – August 2021. This study used closed, semi-closed, and open-ended questionnaires as research instruments. Then, the data collection procedure was done through Google Forms. The data obtained were then selected using purposive sampling. To get valid and reliable data, triangulation was applied in this study. Triangulation was carried out through interviews with five students whose data were selected randomly. The researchers used descriptive statistics as the data analysis. The study found that the activities most often carried out by students during Study From Home (SFH) are playing on cellphones or laptops, doing assignments, working, and sleeping. Then, related to online learning, students prefer to use WhatsApp Group media and lectures. The preferred assignments or assessments are individual assignments and quizzes. Furthermore, the learning model most favored by students is the face-to-face learning model because students consider online learning ineffective. The results of this study can be used as a reference in choosing the suitable model, method, and learning media. Therefore, online learning can be held effectively and easily accepted by students during the Covid-19 pandemic.

In metric spaces, there are quasi-contraction mappings and Suzuki-contraction mapping, that are generalization of contraction mappings. In this article, we give coincidence point theorems of quasi-contraction mappings and Suzuki-contraction mappings in modular spaces, that are generalizations of fixed point theorem of quasi-contractraction mappings and Suzuki-contraction theorem in modular spaces.

Penelitian ini bertujuan untuk memberikan definisi pemetaan (psi,varphi)_omega-kontraksi dalam ruang p-metrik modular, memberikan teorema titik tetap untuk pemetaan (psi,varphi)_omega-kontraksi pada ruang p-metrik modular, dan memberikan aplikasi dari teorema titik tetap tersebut. Penelitian ini menggunakan metode studi literatur. Hasil penelitian menunjukkan bahwa pemetaan (psi,varphi)_omega-kontraksi didefinisikan dalam ruang -metrik modular dengan memperumum pemetaan (psi,varphi)_omega-kontraksi dalam ruang p-metrik dan teorema titik tetap untuk pemetaan tersebut pada ruang p-metrik modular yang juga merupakan perumuman dari teorema titik tetap tersebut pada ruang p-metrik dengan penambahan beberapa sifat yang diasumsikan. Selain itu, hasil penilitian lainnya adalah aplikasi teorema titik tetap tersebut yang menjamin eksistensi solusi suatu persamaan integral yang juga merupakan perumuman dari aplikasi teorema titik tetap tersebut dalam ruang p-metrik. Dari hasil tersebut, dapat disimpulkan bahwa pemetaan (psi,varphi)_omega-kontraksi dapat didefinisikan dalam ruang p-metrik modular dan dapat dibuktikan teorema titik tetap untuk pemetaan (psi,varphi)_omega-kontraksi pada ruang p-metrik modular beserta aplikasi dari teorema titik tetap tersebut yang menjamin eksistensi solusi suatu persamaan integral.
