Abstract

A tracer study is a survey of graduates tracks alumni activities after graduating from an educational institution, Lancang Kuning University is one of the educational institutions that have a tracer study system. A system can be said to be good if it has good usability. So the purpose of this research is to find out whether the tracer study system of Universitas Lancang Kuning has good usability. The heuristic evaluation method will be used to measure usability using 10 aspects of usability heuristics with a questionnaire media in collecting data. Before distributing the questionnaires, an instrument test such as the Gregory test will be carried out by involving system experts and linguists. Then a validity test will be carried out, a reliability test will be carried out after that a heuristic test is carried out by distributing questionnaires. Based on the calculation results that the lowest percentage is owned by the visibility of the system status variable by 75% and the highest percentage results in the match between the system and the real world and consistency and standard with the same calculation results obtained by 81%. The results of the analysis show that the tracer system of Universitas Lancang Kuning has high usability with an average percentage of 78%.

Abstract

Covid-19 has hit many countries in the world, including Indonesia. The rapid and deadly spread of Covid-19 reached Indonesia in early 2020. This pandemic of course had a detrimental impact on the Indonesian people in terms of health, economy, education and others. The Indonesian government certainly does not remain silent, the government is aggressively making efforts to break the Covid-19 chain in various ways, one of the efforts made is to continuously inform about the health protocols recommended by the government to prevent transmission. The Indonesian Ministry of Health (in Mardhia et al., 2020) Efforts that can be made in the prevention phase by each individual include: Wearing a mask, Wearing gloves, Using hand sanitizer/disinfectant, Washing hands with soap, Avoiding touching the face, Avoid shaking hands, Avoid gatherings or long queues, Avoid touching objects/object surfaces in public areas, Avoid taking public transportation, Maintain a distance of at least two meters from other people when outside the house, and If you show symptoms of illness, immediately notify the people around. Even though they have been informed about the prevention of Covid-19, the public tends to be negligent in implementing health protocols, one of which is the application of Social Distancing. Therefore, this study will create a distance detector using the YOLOv3 algorithm as one of the detection objects for the implementation of community activity restrictions
