Education is a learning process with the aim of educating to develop self-potential. The Covid-19 pandemic has an impact on the education sector where face-to-face learning becomes online learning. The purpose of this study is to find out the implementation of online math learning in vocational students during the Covid-19 pandemic, in addition to looking at inhibiting factors in the implementation of online learning carried out during the Covid-19 pandemic. The research method used is a qualitative descriptive method. The research was conducted at SMKN 1 Maniis in Purwakarta Regency, the subject of this study was a class XI vocational student with a total of 96 students. The instruments used in the study are non-tests in the form of open questionnaires and interviews. The research procedure is carried out in three stages. (1) the preparatory stage, (2) the implementation stage, (3) the evaluation stage. The results of the study came to several conclusions, that the implementation of online mathematics learning at the time of Covid-19 was carried out in accordance with the curriculum on Covid-19 conditions, and based on the circular of the Minister of Education and Culture number 4 of 2020 on the implementation of education policy. The online math learning process is carried out using interactive applications such as zoom and google meet in addition to also using google classroom and WhatsApp, in the process of implementation teachers provide the next stage of interaction in the form of Q&A and finally the assignment from the teacher. The inhibiting factor in the implementation of online mathematical learning is inadequate internet network that causes the learning process to be hampered which then has an impact on the lack of understanding of the material that has been delivered.

Mathematics is very important to be taught to students so that they can have and apply mathematical thinking patterns in everyday life and become a reference for studying various other branches of science. One of the Mathematics materials is logarithm material where students often make mistakes when solving these problems, so this study aims to analyze student errors in solving a number of logarithm material problems using the Kastolan procedure. This study used a qualitative descriptive method with the research subject of 10 students of class X Pharmacy in one of the Vocational High Schools in West Bandung. The research instrument used a logarithm material description test instrument as many as 5 questions. Data analysis techniques applied are data reduction, data presentation, and drawing conclusions. Based on the results of the research data, it was concluded that students made conceptual errors, namely the inability of students to apply the concept of the properties used, procedural errors in which students could not solve the problem until they got the final solution, and technical errors occurred because students were wrong in doing calculations so as to produce answers wrong.

Mathematics became one of the mare lessons that a man learned, based on logic and which ranged from the easiest to the most complicated. In addition, we also provide a wide range of products that you can choose according to your needs. analyzing students' mistakes in solving problems can find out whether a student has mastered a material or not. This study has the purpose to describe and analyze the errors of students in solving the soul number root form and the factors causing the error. This type of research uses a description of the quality of the research subject is a student of Class X SMC LPM Padalarang. The sample to obtain data were 6 students representing high, medium and low ability students who were classified from the average results of the root form question test. The Data will be generated in the form of the results of the test questions in the form of descriptions and interviews with several students. From the data collection will result in the analysis of students ' difficulties in solving the problem of root form numbers and the factors that cause it. Difficulties experienced by students include conceptual errors, procedural errors as well as technical errors. Meanwhile, the lack of understanding the concept of root form resulting in misconception is a factor causing difficulties in the material.

This study aims to describe the abilities experienced by students as well as the factors that cause errors made by students in solving the problem of the number of quadratic equations and graphs of quadratic functions. This type of research is descriptive qualitative, with the subject of class IX C Middle School 1 Gunung Middle School Academic Year 2018/2019. Data collection techniques using the test method. The steps of analysis include data reduction, data presentation, and verification. Based on the results of data analysis it can be concluded that in solving quadratic equations and graphs the quadratic function makes a mistake; (1) ability to do questions, (2) ability to understand formulas, (3) ability to transform questions, (4) skill abilities. The causative factor is the communication skills of students who are low, inaccurate, are not accustomed to writing the elements that are known and asked on the questions, and the lack of students to put the results obtained into words.

Upaya mengambangkan keterampilan menulis artikel bagi guru sekolah dasar hingga sekolah menengah sangat mendesak untuk dilakukan. Umumnya guru di Indonesia belum optimal dalam melaksanakan penelitian, membuat laporan penelitian, menghasilkan artikel berbasis penelitian, hingga mempublikasikannya pada jurnal ilmiah. Tujuan pengabdian ini adalah untuk mengembangkan keterampilan guru dalam menulis artikel hingga pada publikasi. Program Pengabdian ini secara optimal dilakukan melalui proses pendampingan bagi guru di Pangandaran dari yang belum memiliki dasar penyusunan artikel ilmiah sampai peserta dibekali dengan beberapa materi untuk memperlancar proses penyusunan artikel ilmiah. Dilakukan pendekatan secara personal dalam pelatihan yang dilakukan sehingga diharapkan agar seluruh peserta dapat menyusun artikel ilmiah dari laporan hasil penelitian tanpa terkendala apapun dengan mengetahui ketentuan-ketentuan penyusunan artikel ilmiah. Pelatihan yang dilakukan dinilai efektif karena peserta bisa merespon dengan baik pertanyaan-pertanyaan yang diajukan dalam angket yang disebarkan setelah kegiatan berakhir dengan hasil mengalami kenaikan. Manfaat pengabdian ini membantu guru-guru di Kabupaten Pangandaran dalam menyusun artikel ilmiah yang berkualitas agar dapat dipublikasikan di jurnal ilmiah nasional.
