Abstract

The purpose of this study was to determine the impact of solidarity buying on the economic resilience of street vendors' families during the Covid-19 pandemic. This study uses a qualitative research method with a descriptive approach. Determination of the subject using purposive to be determined according to the purpose of the study. The subjects in this study amounted to 5 street vendors in Kotabumi, North Lampung. The technique of collecting data is semi-structured interview. Data analysis technique with steps of data reduction, data presentation, and verification. Testing the validity of the data using data triangulation. The results of the ta'awun-based Solidarity buying research were able to increase the income of street vendors during the pandemic. The income of street vendors can increase not only from the profit of buying and selling but from the ta'awun of buyers who often overspend or give alms. Ta'awun really helps street vendors in setting aside money to pay debts. Ta'awun Muhammadiyah activities in North Lampung during the pandemic also helped fulfill the food needs of street vendors, namely the distribution of free basic-necessities to street vendors.

Abstract

“Matematika adalah bahasa simbolis yang maknanya bersifat universal” (Siagian, 2017). Menurut Simamora (2014), “secara etimologis matematika bersumber dari kata yunani mathematike yang berarti bertalian dengan pengetahuan. Jadi, berdasarkan kata asalnya istilah matematika berarti pengetahuan yang diperoleh dari kegiatan belajar”. Matematika termasuk salah satu cabang ilmu pengetahuan yang memegang peranan penting pada perkembangan ilmu pengetahuan dan teknologi, sehingga dapat digunakan sebagai alat bantu bagi disiplin ilmu lain serta perkembangan matematika itu sendiri. Hal itu senada dengan peran penting matematika yang dikemukakan oleh Khotimah (2019) bahwa matematika dikenal luas sebagai alat penting untuk sains, teknologi, perdagangan dan untuk masuk ke banyak profesi.

Abstract

This study aims to identify the difficulties of class X students of SMK Muhammadiyah 1 Kotabumi in studying Mathematics in the Linear Program material. The type and approach in this research is descriptive research with a qualitative approach. The data collection techniques in this study were tests, observations, questionnaires, while for data processing the percentage formula was P = f/n x 100%. From the results of the research, it can be concluded that the difficulties of students in class X SMK Muhammadiyah Kotabumi in Linear Program material are the lack of understanding of students in understanding the concept of Linear Programs, often using formulas incorrectly and still confused in making a mathematical model, as well as the teacher's habit of learning mathematics in a different way. , just take notes on the blackboard, then students lack the desire to complete the sample questions given by the teacher. So it can be concluded that the hypothesis is proven true that there are learning difficulties in mathematics lessons in the Linear Program material for class X SMK Muhammadiyah 1 Kotabumi.

Abstract

Critical thinking is the ability should be owned by the students. However, the facts shows that critical thinking which found is still low. It can be seen from the quality of questions and answers in the process of teaching and learning. Scaffolding is one of learnings which can imrpove students’ critical thinking in mathematic subject. Scaffolding consist of environtment provisions, explaining, reviewing dan restructuring, also development conceptual thinking. There are several scaffolding technique which can be used; (1) modeling of desired behaviors, offering explanations, inviting student participation, verifying and clarifying student understandings, inviting students to contribute clues; (2) scaffolding which emphasize on the use of socratic and open-ended questions.

Abstract

Pembelajaran jarak jauh (PJJ) sudah dikenal dan diaplikasikan sejak lama melalui program yang diselenggarakan oleh Universitas Terbuka maupun oleh beberapa universitas lainnya. Pelaksanaannya dengan cara pembelajaran melalui modul dan mahasiswa dilakukan ujian diakhir semester secara langsung atau luring. Akan tetapi, semenjak diakhir tahun 2019 dengan adanya wabah covid-19, pelaksanaan pembelajaran jarak jauh menjadi keharusan bagi sekolah maupun perguruan tinggi. Implementasi pembelajaran jarak jauh di era covid-19 sangat jauh berbeda dengan pembelajaran jarak jauh yag diterapkan oleh Universitas Terbuka saat itu. Pembeleajaran jarak jauh saat ini dilakukan melalui jaringan internet atau yang biasa disebut dengan pembelajaran daring. Untuk menunjang pelaksanaan tersebut, dosen, mahasiswa, guru, maupun siswa dituntut untuk menguasai penggunaan aplikasi yang dapat digunakan dalam proses pembelajaran daring, misalnya zoom, google meet, whatsshap, dan beberapa aplikasi lainnya. Untuk itu, program studi pendidikan matematika STKIP Bima mengadakan sosialisasi penggunaan aplikasi PJJ dan pengembangan bahan ajar yang diikuti oleh dosen, guru, dan mahasiswa yang dilaksanakan secara online melalui kegiatan webinar. Kegiatan tersebut diikuti oleh 74 orang peserta yang terdiri dari dosen, guru, dan mahasiswa. Implikasi dari kegiatan tersebut adalah peserta mendapat pengetahuan penggunaan aplikasi PJJ dan dapat menerapkan dalam proses pembelajaran daring.
