The outbreak of COVID-19 makes people feel distant from each other, and masks have become one of the indispensable articles in people's daily life. At present, there are many brands of masks with various types and uneven quality. In order to understand the current market of masks and the sales of different brands, users can choose masks with perfect quality. This paper uses Python web crawler technology, based on the input of the word "mask", crawl JD website sales data, through data visualization technology drawing histogram, pie chart, the word cloud, etc., for goods compared with the relationship between price, average price of all brands, brands, average distribution of analysis and evaluation of user information, In this way, the sales situation, price distribution and quality evaluation of each store of the product can be visually displayed. At the same time, it also provides some reference for other users who need to buy the product.

“…Perangkat-perangkat yang dimaksud ialah sebagaimana pada tabel 3 di bawah ini: Membantu penulis dalam memprapharase artikel yang telah diketahui smilaritynya, sehingga persentase maksimum similarity tidak terlampaui Sesuai dengan penjelasan narasumber, pemanfaatan beberapa perangkat di atas akan membantu setiap peneliti dalam menyelesaikan pekerjaannya sehingga menghasilkan artikel ilmiah. Penjelasan narasumber yang dijelaskan di atas relevan dengan berbagai kesimpulan para ahli yang menegaskan bahwa pemanfaatan berbagai perangkat adalah hal yang tidak bisa dipisahkan dengan kesuksesan penyelesaian pekerjaan akademik di masa teknologi informasi (Fiona Willtsher, 2002;Zamawe, 2015;Ishak & Bakar, 2012;Lakshmi, 2018;Sahoo et al, 2019;Cao et al, 2021;Alilli & Krstev, 2019. Untuk mengatur sitasi dalam artikel yang ditulis, penulis juga mesti memanfaatkan management sitasi seperti mendeley, zotero ataupun endnote, pernyataan ini relevan dengan pernyataan para ahli yang mengatakan bahwa tanpa menggunakan management sitasi maka human error dalam menulis rujukan rentan terjadi (Sungur & Seyhan, 2013;Penders, 2018).…”

Produktifitas dosen dalam menulis dan menerbitkan artikel ilmiah pada journal bagian yang fundamental untuk membangun reputasi diri dan lembaga pendidikan tinggi. Namun dalam kenyataan, dosen pada berbagai perguruan tinggi masih banyak yang belum memahami strategi penulisan dan publikasi artikel pada Journal. Oleh karenanya, kegiatan ini bertujuan untuk memberikan pelatihan kepada dosen dalam menulis dan publikasi ilmiah pada journal. Kegiatan ini dilakukanmelalui workshop dengan langkah-langkah penjelasan konseptual, diskusi dan simulasi. Hasil kegiatan ialah dari sejumlah peserta yang mengikuti kegiatan pada awalnya hanya dua orang yang memiliki pemahaman terkait langkah penulisan dan proses pengiriman naskah artikel ke journal yang ditargetkan, namun setelah diadakannya pelatihan semua peserta telah memiliki kemampuan untuk mengirimkan artikel ke jurnal, kegiatan ini juga menghasilkan peserta yang memiliki berbagai akun yang erat kaitannya dengan peningkatan nilai publikasi, seperti google scholar, research gate, Orcid ID, publon ID.

The slump flow and flow time T200 are the main parameters to evaluate the rheological properties of cement paste. Generally, the manual measurement method is used and it is difficult to get T200 accurately. In this paper, an automatic measurement method of slump flow based on dynamic image processing technology is studied. Firstly, the cement paste flowability test video is divided into frames every 100 ms; secondly, based on the principle of perspective transformation, an automatic point selection method is proposed to correct the frame image to solve the problem of shooting angle; thirdly, the watershed algorithm based on distance transformation is used to segment the boundary of the cement paste area, and the slump flow is calculated according to the polar coordinates of the boundary; lastly, the relationship curve between slump flow and time is automatically output, and the slump flow at any time is obtained. The method is verified by nine groups of cement paste flowability tests. The results show that this method can fastly and accurately obtain the slump flow and flow time T200. Compared with the traditional manual measurement method, the measurement error of slump flow is less than 2%, and the measurement error of flow time T200 is less than 8%. The method enables real-time dynamic measurement of the slump flow.
