Abstract

The global market is currently experiencing very fierce competition. Companies compete to implement all marketing strategies to be superior in surviving this competition, one of which is a rebranding strategy by changing the brand image of the X application which was formerly known as Twitter. This study aims to determine whether the effect of rebranding can affect the loyalty of X’s users by assessing brand trust, brand prestige, and brand love. This research method uses a mixed method which is divided into two approaches, namely quantitative and qualitative using linear regression analysis. The results show brand image does not have a big influence on brand trust, brand prestige, and brand love. Furthermore, brand trust, brand prestige, and brand love have a positive influence on brand loyalty meaning that users are not too affected by the rebranding of X, but they will remain loyal to using the application.

Abstract

M-Paspor is a new version of the APAPO application launched at the end of 2021. Since the launch of the M-Paspor application, Indonesian citizens have been directed to submit passport queue applications through the M-Paspor. Batam City is a city that is on international shipping routes and borders directly with Singapore and Malaysia. With these advantages, many Indonesian citizens travel through the City of Batam, causing passport applications in the City of Batam to increase. This research aims to analyze the success of the M-Passport application in the City of Batam using the DeLone and McLean model. The method used in this research is a mixed method of qualitative and quantitative, with 30 qualitative data and 500 quantitative data collected. This research utilizes SPSS and AMOS technology to test validity, reliability, SEM, descriptive statistics, and R Square. The results obtained from this research show that all dependent variables have a positive effect on the independent variables with R Square values obtained as much as 61.3%, 58.9%, and 61.9%. By conducting this research, it is hoped that it can help M-Paspor application developers and the TPI Batam Class I Immigration Office to pay more attention to the quality of information, systems, and services from M-Paspor to improve increase public user satisfaction in public services.

Abstract

The public's need for design services is getting higher, it opens up opportunities for freelancers to offer the design services. Marketplace is a solution to connect the service between users and freelancers. Therefore, the design of the service marketplace needs to be designed smart enough to be able to provide appropriate recommendations and accordance with the user needs. This study builds a web-based design service marketplace that implements a recommendation system with a content-based filtering method with a cosine similarity algorithm that is applied to two objects, namely tags defined by freelancers and users. The results of the study indicate that the design service marketplace system has provided recommendation results in the form of a list of freelancers according to user tags.

Abstract

With advances in technology in the current era, technology can make it easier for MSMEs to record more accurate financial reports so they can continue to survive and adapt to various conditions. The purpose of the research conducted was to analyze the state of MSME De'Sate through internal control using the COSO framework and then to design an information system through the UML Class Diagram and UI Layout Form modeling. The research approach was used by conducting direct observations and interviews with De'Sate MSME owners, with the types of data being primary data and secondary data obtained through literature studies. The research results obtained are as follows: (1) In maintaining the continuity of its business, De'Sate implements internal control with the COSO concept, (2) system design has been made using use case diagrams, UML class diagrams, and the creation of UI Layout forms and systems that made accompanied by a Point Of Sales (POS) so that De'Sate can improve the efficiency of the customer service process.

Abstract

Unhealthy dietary patterns and limited access to personalized nutrition guidance contribute significantly to chronic diseases such as diabetes. These issues highlight the need for a reliable, data-driven approach capable of generating individualized dietary recommendations aligned with nutritional standards. This study aims to develop an Integer Linear Programming (ILP) approach integrated with nutritional datasets to generate personalized and nutritionally balanced meal plans. The goal is to determine whether ILP can effectively balance calorie and macronutrient distribution according to user-specific health profiles while ensuring compliance with dietary guidelines and disease-related restrictions. This study applied an ILP-based optimization framework to calculate total daily energy expenditure and macronutrient ratios, incorporating disease-specific constraints and balanced food distributions across meals. Using 244 standardized food items from clinical dietary data, the model’s performance was validated through comparisons with three AI models (ChatGPT, Gemini, DeepSeek) and a certified medical expert across three evaluation rounds. All AI models indicated that the generated meal plans adhered to macronutrient balance and health-specific requirements. Expert validation produced a mean score of 4.85 out of 5 on a Likert scale, reflecting strong agreement regarding the system’s nutritional adequacy, practicality, and safety. These outcomes confirm the ILP framework’s capability to produce balanced, individualized, and clinically sound meal plans. results demonstrate that ILP-based optimization can effectively generate scientifically sound and practical dietary recommendations, meeting both nutritional standards and user-specific needs. The findings highlight ILP’s potential as a computational decision-support tool that complements professional nutrition guidance. Future work should enhance the objective function by adding parameters that model individual preferences, allergy limitations, and cultural dietary norms, and should incorporate extensive clinical datasets to support adaptive recommendation mechanisms that consider chrononutrition, nutritional adequacy, and preparation methods, along with expert-driven adjustments to portion sizes and meal timing for more tailored dietary guidance.

Abstract

Bullying incidents in schools are often documented in narrative student counselling reports containing informal language, emotional expressions, and contextual dependencies, which pose challenges for automated text classification, particularly under limited labeled data conditions. This study aims to develop a bullying detection model for narrative student counselling reports using a Hybrid CNN-LSTM architecture combined with a pseudo-labelling-based semi-supervised learning approach. The proposed model is trained through a two-stage process, consisting of pre-training on approximately 70,000 publicly available abusive-language texts and fine-tuning using 1,000 anonymized student counselling reports validated by guidance counsellors. Pseudo-labelling is employed to expand the training data while preserving domain relevance and adhering to ethical considerations. Experimental results show that the proposed model achieves an accuracy of 0.8698, a recall of 0.8570, and an F1-score of 0.7951. Although the precision value (0.7415) is relatively lower, higher recall is prioritized to reduce the risk of overlooking potential bullying cases in the school counselling context. Comparative analysis with Logistic Regression and Linear SVM indicates that the Hybrid CNN-LSTM model demonstrates more stable performance when processing longer narrative inputs that require contextual interpretation. This study contributes empirical evidence on the effectiveness of semi-supervised deep learning for bullying detection in low-resource, narrative student counselling data, a setting that remains underexplored in prior work.
