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

Community Service Activities carried out in the Kebumen Regency NU Branch Conference process were carried out because the problems faced during the previous conference were build-up and long queues during registration, so an online-based system was created to handle this. The aim of implementing a digital registration system (SiregalNU) is to speed up implementation of registration services, digitize registration and as a digital literacy moment for NU residents in Kebumen district. This PKM activity was carried out by 15 UMNU lecturers and students. The implementation of siregalNu and the konfercab registration process were carried out for 5 days. The result of this activity is the NU digital registration system (siregalNu) which can be accessed at siregalnu.com. The main output in Siregalnu is an ID-card which has a QR code containing the unique ID of each registrant. The impact that the committee has had is having a complete database related to SK (MWC, Institution, Banom), data on participants from PRNU to MWC under the leadership of the Nahdlatul Ulama Kebumen Branch for the 2020-2024 term of office.

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

Advances in information technology have had a significant impact on village government management, especially in supporting open public information and efficient services. This research explores the implementation of the Spiral Method in developing the Village Information System (SID) to increase transparency in Brengkok Village. The spiral method was chosen because of its flexible iterative approach, allowing the development of a system that is adaptive to user needs. Data collection was carried out through interviews, observations and questionnaires to identify village information needs. The system developed includes main features such as Homepage, Village Profile, Village Government, Village Data, Regulations, Maps, Developing Village Index (IDM), and Admin module. The implementation results show that the spiral method is effective in producing a system that suits village needs, with features that support information accessibility, citizen interaction, and secure data management. This web-based information system is able to increase transparency, public participation, and make it easier for residents to access village information. This research recommends further development with interactive features and technical infrastructure improvements to support system sustainability. Thus, the Village Information System based on the Spiral Method makes a real contribution to realizing a more open, efficient and accountable village government.

The results indicate a significant improvement in the farmers' understanding of digital marketing tools, including social media platforms and e-commerce. Participants gained practical skills in content creation, product promotion, and account management. Despite the success, challenges such as limited internet access and device availability were identified as barriers to effective implementation. The training was well-received, with participants expressing high satisfaction with the practical knowledge gained. In conclusion, the digital marketing training was effective in enhancing the farmers' marketing skills, contributing to better product visibility and market reach. However, further support, particularly in infrastructure and continuous training, is necessary to ensure the sustainability of the program and maximize its benefits for the farmers

Abstract

This community service activity aims to improve the ability of religious activists to use digital technology as a means of preaching in accordance with the progress of the times. Through in-depth training that focuses on creating religious content in short video format, participants receive practical training on planning, shooting, and editing videos with the CapCut application. From this training, ten videos with religious themes were produced that have been widely distributed through the most popular social media platforms such as TikTok, Facebook, and YouTube. In addition to creating inspiring and informative works, this training also succeeded in increasing participants' understanding of digital audience trends and preferences, especially the younger generation. This activity shows that with a relevant approach and proper guidance, religious instructors can transform into adaptive, professional, and transformative preaching content creators. Thus, the spread of religious messages can be expanded through digital media in a way that is humanistic, inclusive, and in line with the characteristics of the times
