Abstract

Traditional attendance systems face challenges related to their vulnerability to human error and limitations in management time. Using a QR Code provides attendance management and recording benefits. The problem that occurred at the Jati Mulya Shop in January - June 2024 was that there were 5 employees who manipulated attendance, causing losses.  Jati Mulya Shop is a fashion shop that has a good reputation and has quite a large number of employees located at Pasar Johar Semarang. The aim of this research is to implement web-based QR Code attendance. The data source in this research is primary data in the form of interviews with business owners. The system development method used is the Prototype model. Before implementing the QR code-based attendance system, Jati Mulya Shop experienced a loss of Rp. 2,810,000 per month, consisting of Rp. 2,500,000 due to absence without permission and Rp. 310,000 due to errors in recording absences. After implementing the new system, efficiency increased 100% so that the loss became Rp. 0. With the QR code system, unauthorized absences and errors in recording absences as well as financial losses are completely eliminated. The hope created by this system can make it easier for business owners to monitor employees and employees who are often absent will also be helped by this system.

Abstract

The conflict between Russia and Ukraine remains one of the major international issues drawing global attention. It began in 2014 with the ousting of President Yanukovych, which triggered a political divide between pro-European Union and pro-Russian factions within Ukraine. Tensions escalated significantly by late 2021, culminating in Russia’s military aggression against Ukraine on February 24, 2022, under President Vladimir Putin’s directive. Twitter, as a social media platform, became a major outlet for the public to express their opinions regarding the conflict. This study aims to analyze public sentiment on Twitter concerning the Russia-Ukraine conflict. The methods used in this research are a combination of the Naïve Bayes algorithm and Lexicon Based Features. Naïve Bayes is utilized to classify sentiment data, while Lexicon Based Features assign weights to positive and negative sentiment words in textual data. The results show that this combined method is effective in categorizing public opinions based on their sentiments towards the conflict. This sentiment analysis provides a broader understanding of global perceptions and may serve as a reference for assessing public opinion in digital media contexts.

Abstract

Palm sugar is the flagship product of Pernasidi Village, Banyumas Regency, which is managed in an integrated manner by KUB Merci. KUB Merci faces several obstacles in the production and management process, including a lack of knowledge about food safety and digital marketing, which results in suboptimal turnover. Traditional production methods also affect the cleanliness of the production kitchen, increasing the risk of contamination. This community service aims to improve participants' understanding of Good Processed Food Processing (CPPOB) and digital literacy. The program is carried out through three stages: pre-service, implementation, and post-service, based on Participatory Rural Appraisal (PRA). The methods used include socialization and training, including material provision, hands-on practice, and discussion. The results of the program showed a significant increase in participants' understanding of CPPOB (72%) and digital marketing (52%). In addition, the evaluation of participants' satisfaction with the program showed positive results with an average score of 3.87. The long-term impact of this program is expected to improve the production standards and competitiveness of palm sugar products from Pernasidi Village through the sustainable application of CPPOB and digital marketing. The program is also expected to contribute to an increase in KUB Merci's turnover and the economic welfare of the local community. However, a thorough implementation of CPPOB and intensive assistance in social media management is needed for the artisans to maximize marketing and expand market reach.

Abstract

Dee Canteen at Ma Chung University faces challenges in knowledge management related to operations, including a lack of documentation for tacit and explicit knowledge such as quick cooking techniques and kitchen SOPs. This study aims to develop a Knowledge Management System (KMS) using the Knowledge Management System Life Cycle (KMSLC). The research methodology includes collecting tacit knowledge through expert interviews, converting the knowledge into explicit forms, and designing a system based on a Knowledge Map. The results of the study show that the implementation of KMS can enhance knowledge documentation and transfer, support operational standardization, and improve the quality of canteen services. The designed system includes key features such as recipe documentation, SOPs, and customer feedback, which can be efficiently accessed by the team.
