Abstract

The development of technology in online transportation services like Gojek has a significant impact on meeting the mobility needs of modern society. The city of Salatiga, with many students from outside the island, has a considerable number of individuals without their own vehicles who prefer to use Gojek services. Therefore, research was conducted to analyze the preferences of students in Salatiga in determining the type of Gojek online transportation using the Naïve Bayes method. One hundred questionnaires from Salatiga students were collected, and the results yielded probability values for Gojek service preferences based on a combination of variables such as weather, load, destination, and time. It is evident from the probability values that weather and time variables play a crucial role in influencing users' decisions between using Go-Ride or switching to Go-Car. These results can provide guidance for Gojek in designing service innovations that are more responsive to user needs based on various specific factors.

Abstract

In the automotive spare parts industry, efficient supply chain management is the backbone of operational success. Amidst this complex ecosystem, companies face challenges in delivering fast, reliable, and competitive services, accommodating a constantly evolving consumer base with discerning preferences and rising expectations. This article aims to identify challenges in developing tracking and delivery scheduling applications for the automotive spare parts industry and improve system performance by introducing effective solutions. The research adopts a system development approach using the Waterfall method to produce a responsive and user-friendly web application, followed by functional testing using Black Box and evaluation using the System Usability Scale (SUS). Development of the tracking and delivery scheduling application using the Waterfall method resulted in a reliable and responsive application, with all system functionalities running smoothly. SUS testing indicated that the application has a good level of usability, with an average score of 77.5 out of 100. This study successfully provides relevant and efficient technological solutions to overcome operational barriers in the automotive spare parts industry, with the potential to enhance customer satisfaction and solidify the company's position as a pioneer in the automotive aftermarket sector. However, further improvements in application usability can be achieved through future iterations guided by user feedback and additional usability testing.

IGiven the rapid development of technology, education in the field of technology becomes crucial for everyone. One of the roles of technology education in fostering someone's creativity can be achieved through learning about things that require creativity, such as animation in the digital world. The Information Systems Program at Atma Jaya Catholic University of Indonesia organized a community service activity in the form of a workshop on November 25, 2023, covering the introduction to the basic concepts of 2D and 3D animation. The workshop was facilitated by Edwar Juanda, S.Ds., M.Ikom, as the speaker, and was attended by 90 participants from high schools and vocational schools in various areas around the Banten province. The workshop proceeded smoothly, and the participants appeared very enthusiastic and active throughout the event. Particularly during the workshop session, participants took turns trying out Virtual Reality tools provided by the speaker. The evaluation through a questionnaire received a positive response from participants with a score of 4.12, indicating agreement. It is hoped that this workshop will provide a broader insight into the younger generation regarding the application of technology, especially in the creation of 2D and 3D animations.

Abstract

A recession is a significant reduction in economic activity and is spread across the economy at its greatest for more than a few months, but it can also be seen in Real GDP, Real Income, Employment, Industrial Production, and Wholesale-Retail Sales. Recently, there has been a lot of public opinion regarding the recession that will occur in 2023, especially in Indonesia, on various social media such as Twitter. Based on these problems, sentiment analysis was carried out on tweets to obtain information on the positive or negative polarity of these opinions using the Naive Bayes and Support Vector Machine (SVM) methods to choose a more effective way in case studies to determine sentiment predictions. The steps are taken consist of data collection, processing data, weighting data, classification process, evaluation, validation, and results and discussion. The web scraping technique was used, and after going through the data cleaning stages, a total of 780 tweet data was obtained. The results of the classification test show that the SVM method has a greater accuracy rate with a proportion of 79.5% compared to the Naive Bayes method with a proportion of 72.5%. The SVM method's prediction results also show several 144 positive and 636 negative sentiments. Judging from the Wordcloud that was formed, it can be assumed that people are worried about their economic conditions, one of which is the unstable oil price which can trigger a recession.

Abstract

Rose of Sharon Church (ROSC) Salatiga, as a rapidly growing spiritual community, faces challenges in managing the increasing number of congregants, especially during events and compliance with health protocols. This significant growth necessitates more effective attendance management to avoid overcrowding. This research addresses this need by developing the ROSC Worship Reservation application based on Progressive Web Apps (PWA) using the Flutter Framework. The application aims to simplify congregants' worship reservations, reduce crowds, and support church administrative tasks. The use of Flutter as the primary framework provides advantages in rapid development and a user-friendly interface. The results of the User Acceptance Test (UAT) show a high satisfaction rate, reaching 92%, regarding the application's functionality and user interface. Additionally, 84% of respondents state that the seating layout displayed by the application significantly aids in effectively choosing seats. It is hoped that the application will continue to provide benefits in managing congregational attendance systematically, efficiently, and in compliance with health protocols. The conclusion of this research emphasizes that the ROSC Salatiga Worship Reservation has successfully created an innovative solution to support church management amid the dynamic growth of congregational attendance.
