Abstract

This study aims to analyze public sentiment toward the government on TikTok and X (formerly Twitter) using the Support Vector Machine (SVM) algorithm optimized with the Synthetic Minority Over-sampling Technique (SMOTE). Data were collected through keyword-based scraping of posts containing the word “pemerintah” (government) and processed using standard NLP pre-processing techniques. Results show that SVM combined with SMOTE significantly improves classification accuracy from 61% to 76% on TikTok, and from 74% to 86% on X. Word cloud analysis confirms these findings: TikTok content tends to reflect neutral and positive sentiments, while X contains predominantly negative expressions. These differences highlight platform-specific public discourse characteristics. The findings suggest that public communication strategies should be tailored accordingly: TikTok for positive narrative and outreach, X for monitoring feedback and criticism. This approach demonstrates the effectiveness of machine learning-based sentiment analysis in supporting data-driven public policy communication.

Abstract

The manufacture of industrial enzymes from trash provides a sustainable remedy for environmental issues. This work investigates machine learning methods to enhance enzyme production from industrial waste by examining critical factors such as waste type and chemical makeup. Three algorithms—Linear Regression, Decision Tree, and Neural Network—were used to estimate and forecast enzyme production. Evaluation criteria, such as Mean Squared Error (MSE) and Coefficient of Determination (R²), were used to evaluate model performance. The results indicated that the Decision Tree method was the most effective, exhibiting lowest error and enhanced accuracy in selecting ideal production factors such as fermentation temperature and time. This method improves efficiency, lowers operating expenses, and encourages sustainable waste management practices. The results highlight the potential of machine learning to convert trash into useful industrial goods, providing a route to more sustainable biotechnology. Future study may enhance hybrid algorithms, include new waste factors, and facilitate real-time implementation for wider industrial applicability.

Abstract

Empowering Household Micro, Small, and Medium Enterprises (MSMEs) is a primary focus in local economic development and community economics. One crucial aspect in enhancing the competitiveness and capabilities of Household MSMEs is effective packaging design. Packaging design is not merely about visual aesthetics but also about functionality and interaction with consumers. The Participatory Learning and Action (PLA) method is utilized to develop effective packaging designs, involving MSME actors, consumers, and other relevant parties. This PLA approach is expected to assist Household MSMEs in facing tight market competition. This research proposes community empowerment activities through the production of Rempeyek products in one of the MSMEs in Majalengka, using the PLA method. The success evaluation of the activities is conducted through the four-level evaluation model (Kirkpatrick), covering reaction, learning, behavior, and results. The evaluation results show an improvement in participants' knowledge, understanding, and skills in packaging design. The overall scores indicate that these activities successfully achieve the Kirkpatrick evaluation goals. Recommendations to enhance the implementation of this service development include increasing the capacity of project participants, addressing deeper issues, local government support, and support for domestic industries. This research demonstrates that training and mentoring in packaging design can provide significant benefits to Household MSMEs, enhancing product quality, market value, and competitiveness in a competitive market.

Abstract

This community service activity aims to integrate Internet of Things (IoT) technology into the monitoring system of a Microhydro Power Plant (PLTMH) in Argamukti Village, Majalengka Regency. The village has significant renewable energy potential, but challenges in real-time energy production monitoring have hindered the plant's optimal performance. By implementing an IoT-based monitoring system, the operational efficiency of the PLTMH can be significantly improved. This program includes training in IoT device installation and guidance for local communities in operating and maintaining the system. The results show a 20% increase in energy production efficiency compared to the period before the monitoring system was implemented. Furthermore, the local community is empowered to manage energy resources independently, supporting the establishment of Energy Self-Sufficient Villages. This initiative aligns with government efforts to promote renewable energy usage in rural areas. The IoT technology implementation also opens opportunities for applications in other sectors such as smart farming and water management, which can sustainably enhance the local community's welfare.

Abstract

The increasing volume of domestic wastewater, particularly greywater, has raised the demand for intelligent and adaptive treatment systems to support efficient water reuse. This study aims to develop a classification model for filtration media types (physical, chemical, and biological) based on water quality data using the Random Forest algorithm. Initial labeling was conducted using the K-Means Clustering method on a publicly available dataset simulated as greywater, based on ten key water quality parameters relevant to irrigation and environmental standards. Model evaluation demonstrated excellent classification performance, with a macro F1-score reaching 0.97 and consistent results in both 5-fold and 10-fold cross-validation. These findings indicate that the proposed model can be integrated into an IoT-based biofiltration system as an automated classification logic to support adaptive, efficient, and reusable household wastewater treatment in the context of irrigation.

Abstract

Employee absenteeism is a very important factor in a company or agency. The punctuality and integrity of employees who are assessed will help the development of the institution/institution. An attendance system that has up-to-date software is very important, because it has positive benefits for the institution or agency, especially interms of effectiveness, efficiency and speed. Along with that attendance is also not only done manually, but can help by using information technology. Attendance carried out at the Office of the KB Sub-District of Pengingkiran is still done manually, namely employees fill in attendance with signatures as well as the time of arrival and departure time. So, there are still a lot of problems when using the manual attendance system, such as not entering without information, coming and going home from the office not according to regulations, leaving the office during working hours and not knowing the leadership and there are still many problems caused. So that the KB Office of the Pengingkiran District requires an attendance application. With the application of the Employee Attendance Data Processing Information System, the Panyingkiran District Family Planning Office was able to overcome the occurrence of absenteeism violations in employees.

Abstract

The Lembah Cisaar Museum in Sumedang, West Java, which exhibits ancient animal fossils, faces challenges in attracting visitors due to limited interactivity and less engaging presentation methods. This study aims to improve the visitor experience through the development of an Android-based Augmented Reality (AR) application. The research employs the Multimedia Development Life Cycle (MDLC) method, consisting of concept, design, material collecting, assembly, testing, and distribution, combined with usability testing. The developed application integrates 3D fossil visualizations, interactive markers, and voice-over narration using Unity, Blender, and Vuforia. Usability testing involving 40 respondents indicated that 89% of users found the application engaging, 91% reported increased interest in visiting the museum, and 92% considered the information beneficial. These findings demonstrate that AR technology can significantly enhance educational value, interactivity, and visitor engagement. The implementation of this AR application provides a modern digital solution to introduce cultural heritage, supporting the transformation of museums into accessible and technology-based educational platforms
