Abstract

The Covid-19 pandemic gives an impact on education field. The face-to-face learning pattern in schools has shifted to distance learning which is carried out online. The implementation of online learning during the pandemic forces a digital transformation in education, causing several problems, two of which are technology and human resources. This article discusses the appropriate online learning strategies to use during a pandemic, especially for synchronous interaction models. Qualitative research with a narrative approach was used to explore teachers' experiences in learning, especially those related to the form of interaction between teachers and students during the Covid-19 pandemic. Active learning was chosen based on the results of observations and literature review through journal articles and proceedings that discuss interactive distance learning methods. Active learning strategies assisted by video conferencing applications that can be applied in online learning in elementary schools include: the use of Student Response Systems; Think Pair Share; One Minute Paper; Small Group Discussion; and Short Student Presentations.

Abstract

In the digital age, the role of information technology is needed to face competition in the community. Information and communication technology is an important element in contributing to changes that are fundamental to the structure of operations and management of organizations, education, transportation, health, and research. The internet is like two sides of a coin, the content offered is positive and negative, both are very dependent on the behavior of its users. The ease of access to the internet is increasingly being felt by the public with increasingly cheap hardware such as tablets and laptops as well as wider connection support. Various efforts to stem negative information continue to be pursued by various elements of society, but it is not effective if the user behavior is not changed. Teenagers are among the most vulnerable in the misuse of advances in internet technology, so it needs serious efforts to provide the right knowledge and skills in utilizing these advancements. By conducting workshops and motivation to improve the abilities and skills of Girimarto 1 High School students, it is hoped that school students can face the development of the digital era more readily. The results of this training gained a high level of satisfaction with the material that had been carried out.

Abstract

Acute myeloid leukemia (AML) adalah salah satu tipe kanker darah yang mengakibatkan sumsum tulang tidak dapat menghasilkan sel leukosit jenis myeloid yang matang. Pada dasarnya diagnosa penyakit AML menggunakan basis perhitungan jumlah persentase relatif sel leukosit dalam darah. Kesalahan dalam perhitungan jumlah sel dapat berimbas pada kurang tepatnya diagnosa yang dibuat. Dalam pemrosesan citra apusan darah secara digital, salah satu hal yang masih menjadi kendala adalah sel darah yang saling bersinggungan dan bahkan tumpang tindih. Penelitian ini mengusulkan perpaduan algoritma active contour without edge (ACWE) yang dikombinasikan dengan watershed distance transform (WDT) untuk dapat mengatasi permasalahan objek sel darah yang tumpang tindih. ACWE digunakan untuk melakukan segmentasi objek sel darah berbasis perhitungan inside energy dan outside energy sementara WDT diimplementasikan sebagai algoritma pemisah objek dengan memanfaatkan memanfaatkan transformasi jarak dari setiap piksel ke nilai piksel non-zero terdekat. Hasil penelitian menunjukkan dari total 876 objek sel leukosit, terdapat 734 objek yang dapat disegmentasi dengan baik dan sisanya sebanyak 142 objek masih belum dapat diseparasi dengan tepat. Nilai ini menunjukkan bahwa perpaduan algoritma ACWE dan WDT dapat memisahkan 83,789% objek sel leukosit dari citra AML M1, M2 dan M3.
