In the early 2020s, Indonesia was shocked by the Coronavirus Disease (Covid-19) outbreak which struck almost all parts of the world. The Indonesian government spontaneously implemented a policy of learning from home, working from home, and worship at home. All face-to-face activities are diverted online. In the field of education, both universities and schools need to strengthen online learning during this time. Universitas Negeri Surabaya has an alternative in carrying out a proposal / thesis seminar by using virtual meetings. The virtual meetings used include: meeting.unesa.ac.id, rv.unesa.ac.id, zoom, google meets, Webex and others. This study aims to determine students' perceptions of the virtual meeting features as a means of online proposal / thesis examination in the middle of a pandemic. This study can be a reference whether the use of virtual meetings as an alternative in carrying out a seminar proposal / thesis is effectively implemented. The research focuses on students' opinions on the usability factor (PU) and convenience factor (PEOU) in virtual meeting features following the Technology Acceptance Model theory. This research was conducted by quantitative methods. The sample used in this study were students of Universitas Negeri Surabaya who were taking the thesis. Data collection techniques using a questionnaire with a Likert scale. Then the results of the questionnaire data are processed using the Structural Equation Model (SEM) with SPSS tools. The results of the study stated that the research indicators related to user satisfaction in utilizing virtual meetings as an alternative for implementing seminar proposals / theses passed the validity, reliability, and linearity tests. Validity test value> r table. The value of the alpha reliability test was between 0.70-0.90. While the linearity test value> 0.05.

Indonesia in the early 2020s was being rocked by the outbreak of Coronavirus Disease (Covid-19) which hit almost all parts of the world. Indonesia spontaneously implements a policy of learning from home (SFH) and working from home (WFH). Higher education during the WFH period needs to strengthen online learning. Universitas Negeri Surabaya has had e-learning developed using Moodle LMS and has been used as a form of learning called Vilearning Unesa (Vinesa). The research aims to measure the implementation readiness of Vinesa. This measurement needs to be done as an effort to support the successful development of e-learning. To know which factors are still weak and require improvement and which factors have been considered successful or strong in supporting the implementation of Vinesa. There are eight indicators used to measure the readiness of e-learning, namely the psychological readiness, sociological readiness, environmental readiness, human resource readiness, financial readiness, technological skill readiness, equipment readiness, and content readiness. However, this research focuses on one indicator that is directly related to students, namely content readiness. The research method used is qualitative research methods. The study began with a literature study on e-learning readiness. Then an indicator is set to be reduced to the items in the questionnaire. The object of research is students of Informatics in Universitas Negeri Surabaya.

Proses segmentasi nukleus dan sitoplasma dibutuhkan dalam sistem diagnosa otomatis pemeriksaan kanker serviks karena dapat mempengaruhi keakuratan sistem. Sebuah algoritma energi eksternal untuk active contour (snake) dengan menggabungkan metode Normally Biased Gradient Vector Flow Snake dan Generalized Gradient Vector Flow Snake diusulkan pada penelitian ini. GGVF dapat memperbesar jangkauan konvergensi kontur aktif, meningkatkan kinerja konvergensi dan lebih handal terhadap noise, serta NBGVF dapat memberikan solusi untuk masalah perlindungan tepi yang tipis. Oleh karena itu, penelitian ini menggabungkan GGVF dan NBGVF untuk mengusulkan versi energi eksternal yang baru yang disebut Normally Biased Generalized Gradient Vector Flow Snake (NBGGVFS). Radiating Edge Map dimanfaatkan sebagai fungsi edge map snake pada penelitian ini. Penelitian ini bertujuan untuk segmentasi sitoplasma dan nukleus citra sel tunggal smear serviks menggunakan metode Radiating Normally Biased Generalized Gradient Vector Flow Snake. Metode usulan terdiri atas tiga proses utama, yaitu pra proses, proses segmentasi awal dan segmentasi akhir. Metode segmentasi awal yang digunakan pada penelitian ini adalah mean shift clustering. Dataset yang digunakan adalah dataset Herlev. Proses uji coba dilakukan dengan cara memvariasikan nilai bandwidth metode segmentasi awal dan dengan membandingkan nilai akurasi dan ZSI metode usulan dengan metode penelitian sebelumnya. Berdasarkan uji coba, nilai rata-rata Zijdenbos Similarity Index (ZSI) dan akurasi untuk segmentasi nukleus adalah 96,96% dan 90,68%, dan untuk sitoplasma adalah 86,78% dan 89,35%. Hasil pengujian menunjukkan metode yang diusulkan mampu mendeteksi area nukleus dan sitoplasma pada citra sel tunggal smear serviks lebih optimal dibandingkan metode sebelumnya sehingga dapat digunakan sebagai metode segmentasi pada sistem identifikasi kanker serviks.

The use of e-learning has become common in educational institutions. This is further supported by the obligation to implement online education during the COVID-19 pandemic. E-learning is a system that is anticipated to not only replace traditional learning techniques and resources but also to introduce fresh, cutting-edge approaches to the way we currently learn. The goal of this study was to identify the characteristics that contributed to the application of vinesa's success and had an effect on the growth of vines users. Within the Surabaya State University. Applying the DeLone McLean IS Model technique, measurements were done with an emphasis on the system quality factors, information quality, and service quality in information systems. The results showed that the quality of the system and the quality of information significantly affected sustainable use. While the quality of service does not have a significant effect on sustainable use.
