Abstract

Since the emergence of the Covid-19 virus in Indonesia, learning activities in the education system have been changed to distance learning using online media. The most widely used application according to the results of interviews with teacher representatives from 4 vocational schools in Karawang Regency is Google Classroom. However, the application received a poor rating based on the rating on the Google Play Store. So that usability testing is carried out in order to assess the effectiveness, efficiency and user satisfaction of the application. There are several usability testing techniques, including (SUS) System Usability Scale and Usefull, Satisfaction and ease of Use (USE) Questionnaire. This study aims to obtain the results of usability testing and a comparison between the two techniques used. Both have some similarities where the analysis can be done using any media, it's just that there are differences in the number of questions and data analysis. The System Usability Scale (SUS) technique contains 10 questions while the Usefull, Satisfaction and ease of Use (USE) Questionnaire technique contains 30 questions with 3 main dimensions, namely Usefulness, Satisfaction and Ease of Use. The research method used is Product Moment Pearson’s method for data validity analysis and Cronbbach's Alpha method for data reliability analysis. This research is a quantitative descriptive study conducted on 50 high school students/equivalent and university students. The results of the questionnaire technique (SUS) System Usability Scale state that Google Classroom has a good interface with a score of 72 with advantages in ease of use and desire to use it again, while based on the Usefull, Satisfaction and ease of Use (USE) Questionnaire technique states Google Classroom has an average value of 84% with 81% (usefulness), 86% (ease of use), 87% (ease of learning) and 83% (satisfaction). Then according to the comparison, the Usefull, Satisfaction and ease of Use (USE) Questionnaire technique is stated to be better with a reliability value of 0.967 while (SUS) System Usability Scale only has reliability (0.634).

Abstract

The problem that occurs at the Karawang National Narcotics Agency (BNNK) is that there is no information regarding existing asset data, both from the name of the item, year of acquisition, item code, and item serial number. Therefore, the author will create a QR code that contains information about the items in BNNK so that it can be easily accessed and information about these items can be known and can make it easier for employees there when the Ministry of Finance will audit the items related to assets at the BNNK office. Therefore, this study proposes a research related to asset management using a QR code for items at BNNK. The method used in making this QR code is using the QR generator method to simplify the process of making QR codes and making designs for QR codes that will made. For testing the QR code we use beta testing so that we can know in advance the performance and output generated by the QR code. This study produces a QR code that is in accordance with the request of related parties and makes it easier for employees in the goods section to find out data about assets owned by BNNK and help BNNK to carry out asset management on items in the office.

Abstract

In the process of monitoring the capacity of the B3 waste storage facility at PT Fadira Teknik, the manual method is still used to determine whether the waste load is full (ready to be disposed) or not. Where in the process, workers must come and look directly at the B3 waste storage area. This will increase jobs for factory workers because they must always monitor the level of B3 waste before or after carrying out work. Apart from being harmful to humans, the B3 waste disposed of from the factory is in the form of small particles such as invisible dust which can be accidentally inhaled by the nose or into the eyes of the workers. Therefore the aim of this research is to create a smart trash can system that can monitor the volume of B3 waste in the trash, where the trash uses the IoT (Internet of Things) system by utilizing the Arduino Uno component as a microcontroller and ultrasonic sensor to detect the volume of waste then sends waste volume data to the Blynk application via the internet network to display information on the capacity of the trash. The research method used is the experimental method starting from system analysis, system design, system implementation, testing and evaluation. Testing on this smart trash system uses black box testing with the results of these tests being quite good where each test case is as expected.

Abstract

Regulation of the Minister of Education, Culture, Research, and Technology (Permendikbud Ristek) Number 30 of 2021 was launched as a form of government efforts in the context of preventing and handling sexual violence in universities. However, it turns out that this regulation has generated various reactions from the community, most of them support it while others reject the ratification of this regulation. Technological developments that occur today encourage people to write their opinions on social media, one of which is Twitter. Tweets discussing this rule can be used to gauge public sentiment. However, considering the number of tweets, the classification process will be difficult to do manually, so it requires a computational system that can automatically classify the sentiments of the existing tweets. From these problems, a system is designed to perform sentiment analysis using the lexicon-based method and Multinomial Naïve Bayes. The results of this sentiment measurement can be useful as data analysis material for the Ministry of Education and Culture, Research and Technology in making decisions regarding this rule. The purpose of this research is to measure the value of accuracy, precision, recall, and f-measure in sentiment analysis using lexicon-based and Multinomial Naïve Bayes methods. The measurement results obtained using a dataset of 470 data are the accuracy value of 71.28%, precision of 70.10%, recall of 78%, and f-measure value of 74.29%.
