Abstract

Traditional market vendors play a vital role in supporting local economies and contribute significantly to community economic activities. However, most of them have not implemented proper bookkeeping systems, resulting in difficulties in managing cash flow, calculating profits, and accessing formal financial services. This program aims to provide simple bookkeeping assistance to traditional market traders to help them gain basic financial record-keeping skills. The program involved initial observation, development of a simple bookkeeping module, in-person training sessions, and hands-on assistance in daily financial recording. The bookkeeping system was tailored to the needs of small-scale businesses, covering records of income, expenses, and profit-loss, using notebooks and easy-to-understand paper forms. The results indicated an increased awareness among traders about the importance of financial documentation and their ability to independently create basic financial reports. Additionally, some vendors expressed interest in saving and accessing banking services as part of improved financial management. This initiative had a positive impact on enhancing the financial literacy of traditional traders and encouraged the development of a more organized business administration culture. In the future, such mentoring programs are expected to continue periodically and evolve toward the digitalization of simple bookkeeping systems via mobile applications.

Abstract

Urban waste management faces significant challenges due to the increasing volume of waste, inadequate infrastructure, low public awareness, and limited use of technology. This community service program aims to develop an information technology-based solution to create a more efficient, environmentally friendly, and community-engaged waste management system. Through the development of a mobile application, residents can report waste conditions in real-time, monitor waste sorting, and access waste collection schedules. The program also includes community training, provision of waste sorting facilities, and educational campaigns to raise environmental awareness. The implementation has shown significant improvements in public participation in waste sorting, reduction in the volume of waste sent to landfills, and overall improvement in environmental quality. Furthermore, this initiative contributes to human resource empowerment through training in technology use and waste management. The success of this program demonstrates that integrating information technology with public education can be an effective solution to urban waste management challenges.

Abstract

This study investigates sentiment classification of user reviews on the iPusnas digital library application to provide an objective overview of service quality and user experience. Numerous complaints related to login failures, application crashes, and issues in accessing digital books indicate the need for a computational approach capable of processing large volumes of user feedback. The proposed method integrates Natural Language Processing (NLP) techniques with the Support Vector Machine (SVM) algorithm. The workflow consists of collecting 2,000 reviews, applying text cleaning and normalization, tokenization, stopword removal, stemming, rating-based sentiment annotation, and feature extraction using TF-IDF. The dataset was divided using a train–test split for model training and evaluation. Experimental results show that the SVM model achieves 90.1% accuracy, demonstrating strong performance in detecting negative sentiments and moderate performance for positive sentiments due to class imbalance. These  findings highlight the effectiveness of NLP and SVM for extracting user perceptions and indicate the potential of this model as a decision-support tool for improving iPusnas application services. Overall, the study contributes to the advancement of digital service innovation in Indonesia.

Abstract

This study aims to evaluate the effectiveness of the Chi-Square and Information Gain feature selection techniques in improving the accuracy of sentiment classification on application reviews using the Naive Bayes algorithm. The main issue addressed in this research is the high dimensionality of features in Indonesian-language text data, which may potentially affect model performance. To address this, the study applies a text preprocessing pipeline consisting of sentiment labeling, normalization, and feature extraction using TF-IDF with an initial 5000 features. The dataset contains 225,043 Gojek application reviews, which were reduced to 220,860 valid entries after cleaning, and subsequently divided into training and testing sets using a stratified split. Experimental results show that Chi-Square achieved the highest accuracy of 0.877864 with 3000 features, while Information Gain reached an accuracy of 0.877751 with 4000 features. Both values are slightly lower than the model without feature selection, which achieved an accuracy of 0.878045. These findings indicate that feature reduction does not improve the performance of Naive Bayes, as the algorithm performs more effectively when retaining a broader distribution of words and more complete contextual representations. In conclusion, feature selection for probabilistic models should be applied cautiously, especially on Indonesian-language review data that are informal and exhibit high variation in expression.

Abstract

Micro, Small, and Medium Enterprises (MSMEs) play a strategic role in supporting economic growth and employment generation in Indonesia. However, many MSMEs, particularly in the food and culinary sector, continue to face challenges such as limited product variety, low utilization of digital technologies, and insufficient understanding of market needs. This Community Service Program aimed to enhance the capacity of MSMEs in product innovation and market-oriented product diversification in Cirebon City. The program employed a participatory approach consisting of five stages: partner needs assessment, market needs survey, product innovation workshops, product development mentoring, and evaluation. The participating MSMEs included Dana Kinasih, Syukuri, Torani Sumoer Makmur, Sambal Anakku, and Rumah Kukus. The results demonstrated significant improvements in both innovation capacity and business competitiveness. The total number of products increased from 8 to 16, average monthly revenue rose from IDR 3,000,000 to IDR 4,500,000, and the number of new customers increased by 25%. Furthermore, pre-test and post-test evaluations indicated substantial improvements in participants’ understanding of product innovation, digital marketing, e-commerce, and the application of Artificial Intelligence (AI) in business. Market survey findings revealed that consumers preferred products with modern packaging (85%), diverse flavor variants (70%), and convenient online purchasing options (75%). These findings suggest that market-oriented product innovation and diversification mentoring is an effective approach to improving the competitiveness and sustainability of MSMEs in Cirebon City.

Abstract

The community service activity with the theme "Database Integration and Data Automation Training Using n8n for Information System Optimization" was carried out as an effort to improve the digital competence of vocational high school students and educators in Cirebon Regency in facing the needs of digital transformation. The activity was carried out on April 11, 2026 through workshops, demonstrations, and direct practice using the n8n platform. This program was motivated by the fact that many schools still manage academic data manually using separate spreadsheets, resulting in inefficient data processing, potentially leading to data duplication, and complicating the monitoring and reporting process. In addition, participants' understanding of database integration and workflow automation was still relatively limited. The training material covered basic concepts of information systems, database integration, utilization of APIs and webhooks, and implementation of workflow automation using the n8n platform. Participants gained hands-on experience in building simple workflows, such as integrating Google Sheets with Telegram, synchronizing digital form data, and automating notification delivery. The activity was attended by participants from SMK Presiden Cirebon, SMKN 1 Kedawung, SMK Islamic Center Cirebon, SMK Muhammadiyah Cirebon, SMK Wahidin Cirebon City, and SMK Budi Tresna Cirebon Regency. The results of the activity showed an increase in participants' understanding and skills in applying data integration technology and information system automation. Participants successfully developed various simple automation workflows that can be implemented to support the effectiveness of academic administration in schools. The evaluation of the activity showed that the level of participant satisfaction was in the very good category. In general, this activity succeeded in making a positive contribution to increasing digital literacy, strengthening information technology competencies, and developing the use of n8n-based automation workflows in vocational education environments.
