Abstract

Sentiment analysis on public opinion regarding the shopee food application is an interesting topic in the context of evaluating service quality in the shopee food application. In this digital era, user opinion has a very important role in shaping public perception of the application. Therefore, sentiment analysis is needed to understand user opinion about the shopee food application. This study uses Decision Tree C4.5 to analyze public sentiment on the use of the Shopee Food application on Twitter users. However, beforehand it is necessary to overcome the problem of data imbalance which is common in datasets, where the number of positive, negative, and neutral sentiments is not balanced. To overcome this problem, three different techniques are used, namely SMOTE, undersampling, and a combination of oversampling and undersampling. The results of this study indicate that the SMOTE technique provides better results in overcoming data imbalances and increasing prediction accuracy. With an accuracy of 0.88. the SMOTE technique can provide more accurate sentiment predictions than the undersampling technique and the combination of oversampling and undersampling. This is because SMOTE can synthetically expand the number of minority samples, thereby preventing the loss of information and maintaining variation in the dataset. In conclusion, sentiment analysis on the Shopee Food application on Google Play using the Decision Tree C4.5 algorithm and the SMOTE technique can overcome data imbalances with a prediction accuracy of 0.88. This technique is more efficient than the undersampling technique and the combination of oversampling and undersampling. These results can provide developers with valuable insights to improve app quality and user satisfaction.

Abstract

In the current digital era, promotion through visual media is the key to introducing products or business premises to the public. By using video as a promotional medium, companies can expand their marketing reach and make information more interesting and easy for consumers to understand. The problem faced by Kopi Sembilan is the lack of a creative and attractive promotional strategy, as well as not highlighting their Unique Selling Proposition (USP) in every product they promote. In comparison, their competitors were already using video to promote their products, giving them a significant competitive advantage. By studying the creative and technical aspects behind making advertising videos using live shoot and motion graphic technology, this research produced an advertising video that was rated very good by respondents, with a total percentage of 88.2%. This video was broadcast on Kopi Sembilan's official Instagram and received a positive response from the public. However, this research still has several shortcomings, such as the need to add creative elements such as 3D animation, improve animation smoothing, and add voice dubbing to increase the visual and audio appeal of advertisements. It is hoped that this suggestion can be taken into consideration for further development so that the promotion of Kopi Sembilan becomes better and more effective.

Abstract

Workshops play an important role in supporting the automotive industry, but many small workshops still use manual recording that is prone to errors and complicates operational management. This study aims to design and implement a web-based information system at the AA Motor Workshop in Kembangkuning Village, Purworejo, to improve work effectiveness. The system was developed using the waterfall method, starting from the needs analysis stage to maintenance. Testing was carried out using the Black Box approach, focusing on the main functions of the system, such as customer management, service, stock, reporting, and user authorization. The test results showed that all modules functioned according to needs and no critical errors were found during testing. The implementation of the system had a significant impact, where work efficiency increased by 84%, data accuracy reached 86%, and the speed of the administration process increased by about 40% compared to the previous manual system. All data is now recorded automatically and can be accessed in real-time via a responsive web dashboard. This study shows that digitalization can improve the performance of small workshops, and the system developed can be used as a model for technology adaptation for similar businesses in rural areas.
