Abstract

This paper is a report of a study about the impact of covid-19 pandemic onto the performance of faculties in Universitas Advent Indonesia in academic year 2019/2020. The purpose of this study is to see whether covid-19 pandemic influence teacher performance indicated by the students’ evaluation. The population of the study is all lecturers in UNAI who taught during the odd and even semester 2019/2020, i.e. 91 lecturers. The questionnaire consists of 33 questions involving 5 basic competences of teacher, namely pedagogic (9 items), professional (8 items), personality (6 items), social (5 items) and spiritual (5 items). The teacher performance is analysed using t-test or anova statistical analysis based on faculty, age, gender, and degree. The analysis indicated that (1) there is a significant difference in teacher performance among the faculties, (2) there is significant difference in teacher performance based on age, gender and degree held. This analysis indicated that the covid-19 pandemic does not have any significant impact onto the teacher performance. The difference in the teacher performance among the faculties (departments) may not be due to covid-19 pandemic, since it also occurred before the pandemic. For study the pandemi occurred about 2.5 months, or half semester, since in the middle of March 2020, therefore it is interesting to do a further study whether a long term pandemic has an impact on the teacher performance if the online learning continues.

Abstract

Stock prediction using the K-Nearest Neighbors method is intended to be able to provide predictions that can help the public and investors to find out the share price in the future. Through the literature study stage, interviewing and looking at daily stock price data where the attributes used are daily stock open price, highest price, lowest price, daily stock closing price, selling exchange rate data, rupiah exchange rate against the US dollar, and interest rate data 1 month. The results obtained with the total data are 1415 data, with a total of 70% training data and 30% testing data using the K-Nearest Neighbors method, then the accuracy rate of 61.79% is obtained. Through the confusion matrix the value given for the precision or level of accuracy of the expected information for data classified as experiencing an increase is 62.03% and data experiencing a price reduction is 60.76%, while for the recall value or the success rate for information found for data classified as an increase the price was 87.35% and the data classified as having experienced a price decline was 26.82%.

Abstract

Graduation of a course is very important, if there are students who do not pass a course, especially subjects that have an attachment to another course, must take back the course. Graduation in a course cannot be known before the final exam and final grade calculation are calculated. For this reason, it is necessary to predict the graduation of courses to help anticipate what makes students fail in a course.Through the literature study stage, interviews and looking at academic performance data obtained, the assignment values, unit test values, mid test scores, and attendance obtained from performance data and internal and external factors of students such as class activity, status of residence, language lesson, and the form of the final project given. Data processing is performed using K-means, then calculate the chi square atribute selection and calculate the accuracy of the prediction using a confusion matrix.The results of the study showed that the prediction results using K = 3 of 118 data processed there were 13 students who did not pass, 36 students graduated with sufficient grades, and 69 students graduated with good grades. And what influences the graduation prediction using the chi square atribute is a mid value with ranked atributes of 49, an assignment value of 46, and attendance of 42. Language material using English influences students who graduate with sufficient grades. While the final project in the form of a project or a theory test does not greatly affect the predictions of student graduation in a course. The use of confusion matrix to the prediction results shows an accuracy rate of 93% with precision and recall of 96% and 92%.
