Abstract

Libraries as the heart of higher education play a vital role in supporting the Tri Dharma, particularly in academic and research development. The advancement of information technology demands innovation in library services, one of which is the adoption of Web-Based Library Management Systems (WLMS). This study, entitled Evaluation of the Use of Web-Based Library Management System at I Gusti Bagus Sugriwa State Hindu University, Denpasar, aims to evaluate the effectiveness, challenges, and strategic significance of WLMS implementation using the Technology Acceptance Model (TAM) and the Technology–Organization–Environment (TOE) framework. A sequential explanatory design was applied, combining quantitative surveys and qualitative interviews with 39 respondents consisting of librarians, lecturers, and students. Quantitative findings indicate very good results in perceived usefulness (PU), attitude toward use (ATU), behavioral intention (BI), and actual use (AU), while perceived ease of use (PEOU) scored in the “good” category. TOE-based analysis reveals supporting factors such as infrastructure availability, leadership commitment, and system accessibility, while inhibiting factors include unstable internet, data security concerns, insufficient training, and low digital literacy among users. These results demonstrate that although WLMS significantly improves accessibility, efficiency, and digital literacy, its sustainability requires continuous system optimization, technical support, and human resource development. This research concludes that WLMS adoption at I Gusti Bagus Sugriwa State Hindu University is largely successful but still needs strategic interventions to ensure long-term effectiveness and integration with the university’s mission of advancing Hindu knowledge and culture in the digital era.

Abstract

Water pollution poses a significant threat to public health, particularly in rapidly developing urban areas such as Batam City, where domestic and industrial activities continue to increase. This study aims to analyse and monitor the quality of household tap water in Batam City over a 30-day period using an Internet of Things (IoT)-based smart water quality monitoring system. The research focuses on two key parameters, namely Total Dissolved Solids (TDS) and water temperature, which serve as primary indicators of water purity. Data were collected daily through a TDS sensor and a DS18B20 digital temperature sensor integrated into an IoT platform for continuous monitoring and real-time data acquisition. The results revealed that the water temperature ranged between 28–29 °C, indicating normal conditions for tropical regions and conforming to clean water standards. The TDS values varied from 310 to 355 ppm, remaining below the World Health Organization (WHO) safety limit of 500 ppm. Although slight fluctuations in TDS levels were observed during the observation period, no readings exceeded the acceptable threshold. These findings suggest that household tap water in Batam City is still safe for consumption and daily use. The study concludes that the application of IoT-based monitoring systems offers an effective approach for real-time water quality supervision and recommends regular monitoring along with the use of filtration devices to ensure long-term water safety and sustainability

Abstract

Data security has become a critical aspect in the digital era, especially in protecting confidential files from unauthorized access. This study aims to design and implement a file encryption system based on Object-Oriented Programming (OOP) principles using the C++ programming language. The system is developed by applying the core concepts of OOP, namely encapsulation, inheritance, and polymorphism, to create a modular and reusable software architecture. The encryption process is implemented using symmetric key algorithms, allowing users to encrypt and decrypt text-based files securely. The program design follows a layered class structure, where each class handles specific functionalities such as key generation, file reading and writing, and cryptographic operations. The implementation is conducted in a console-based environment with a focus on simplicity, efficiency, and maintainability of the source code. The evaluation results show that the OOP-based approach enhances the flexibility of system modification and reduces code redundancy compared to traditional procedural programming. Furthermore, performance testing demonstrates that the encryption and decryption processes can be executed efficiently without significant latency for small to medium-sized files. This research concludes that applying OOP concepts in C++ provides a structured and scalable framework for developing secure and maintainable encryption systems, which can be further enhanced for larger-scale or GUI-based applications in the future.

Abstract

Agrarian regions like East Java province face complex public health challenges. Some cases are caused by the interaction between social factors, and others by agribusiness factors. An integrative approach is needed to understand the dynamics of disease cases. This study aims to analyse the disease with the highest number of cases and project case trends in East Java using an integrated quantitative approach. Using methods such as the Analytic Hierarchy Process (AHP) to determine disease weights, the TBATS model is used to project case trends through 2028. Standardised multiple regression models were used to assess the influence of social factors (population density, poverty) and agribusiness (rice harvest area, agricultural labour). The data used are secondary time-series data from 2013 to 2023 obtained from BPS, the Health Department, and BMKG. The AHP results show diarrhoea as the disease with the highest weight (0.494), followed by pneumonia (0.112), tuberculosis (0.090), malaria (0.051), and dengue fever (0.049). The TBATS projection indicates medium-term fluctuations with the potential for an increase in dengue fever cases. Meanwhile, the regression results show that people in the agricultural sector are at increased risk of malaria (p = 0.037), while other variables have an influence but are not significant. Therefore, integrating health, social, and agribusiness data is an urgent need. And it can be used for early disease warning systems and more precise public health policy strengthening.

Abstract

Global warming has triggered extreme weather that negatively affects skin health, including damage, premature aging, and increased risk of skin cancer, prompting the use of skincare products. E-commerce platforms like Sociolla simplify skincare purchases, but the abundance of choices and varying skin reactions make product selection challenging. This study aims to assist consumers in making smarter purchase decisions by analyzing user reviews using sentiment analysis with a lexicon-based approach and the Multinomial Naive Bayes algorithm to classify reviews as positive or negative. The process includes data collection, text preprocessing, model development, and performance evaluation. The results show that this method achieved an accuracy of 80,64%, demonstrating its effectiveness in helping consumers filter reviews and select appropriate skincare products.
