Abstract

The limited availability of air quality sensors leads to potential exposure to pollution that poses health risks. Monitoring of crucial clean air indicators, such as ISPU standards and emission requirements, as well as management of important aspects of healthy buildings such as ventilation, temperature, humidity, and security, are also inadequate. As a solution, this article proposes the development of an Internet of Things (IoT)-based smart school that utilizes advanced sensor technology to monitor and manage the condition of the educational environment in accordance with the healthy building foundation proposed by the Harvard T.H. Chan School of Public Health. With the integration of Tuya-based sensors and the use of HomeAssistant platform for automation, the implementation of this system in educational institutions such as TK Al Baraakah, RA Kreatif successfully created a healthier environment. As a result, better building conditions are achieved through real-time monitoring of vital parameters, forming a structured approach to creating safer and more comfortable schools for students and faculty. Monitoring and management can be shown on the Dashboard of the HomeAssistant platform.

Abstract

Evaluating the performance of contractual employees is a crucial step to ensure operational effectiveness and efficiency within government institutions, including at the Wali Nagari Binjai Office. However, manual evaluation processes often face challenges such as subjectivity and inaccuracy. This study aims to develop a Decision Support System (DSS) based on the Weighted Product (WP) method to provide an objective and transparent solution for evaluating the performance of contractual employees. The WP method was selected for its capability to process multi-criteria data by considering the weights of relevant criteria, such as work discipline, productivity, and attendance. The web-based system automates the calculation of preference values for each employee, simplifying the management process of identifying top performers efficiently. System testing results indicate that this approach produces more accurate evaluations compared to manual methods, with an accuracy rate of up to 90% based on historical data. Additionally, the system is user-friendly and can be integrated with other management processes. This study not only provides practical contributions to the Wali Nagari Binjai Office but also offers a model that can be adapted by other government institutions.

Abstract

Electronic Health Records (EHR) store tabular data that is rich in information and play a critical role in supporting decision-making within the healthcare field, particularly for patient care classification. This study evaluates the performance of two artificial intelligence models, Fully Connected Neural Networks (FCNN) and TabNet, in processing tabular data for patient care classification tasks. The findings reveal that both models demonstrate strong performance, with TabNet showing a slight advantage. TabNet achieves an accuracy of 0.74, marginally surpassing FCNN's 0.73. Furthermore, TabNet excels in precision (0.74 vs. 0.72), recall (0.72 vs. 0.71), and F1-Score (0.73 vs. 0.71), highlighting its greater reliability in minimizing false positives and accurately detecting positive cases with a better balance between precision and recall. With its architecture specifically tailored for tabular data and its capacity for direct interpretability, TabNet offers enhanced efficiency and ease of implementation compared to FCNN, which demands more complex data preprocessing. For future research, it is suggested to employ larger and more diverse datasets, explore data with higher feature complexity, and conduct comprehensive hyperparameter tuning to further improve the performance of both models.

Abstract

Air pollution is a serious environmental problem that can affect human health because it contains toxic gases, one of which is carbon dioxide (CO2). This toxic gas can cause Acute Respiratory Infection (ARI). ARI is an acute infection of the respiratory tract that can cause death. One effort to prevent ARI is to monitor CO2 gas as a trigger for ARI. This study develops intelligent technology for monitoring CO2 concentration using a rule-based artificial intelligence algorithm by utilizing Internet of Things technology integrated with telegrams to provide warnings. Rule-based systems are part of artificial intelligence that have advantages and limitations that need to be considered before deciding whether it is the right technique to use in solving existing problems. This study uses daily data taken by CO2 gas sensors from 07.00 - 16.15 WIB with a data collection range of 15 minutes with a total of 38 data samples taken. The results of the study show that this rule-based algorithm is able to classify CO2 concentrations according to the rules that have been made. In addition, from the data taken, 42% are in the safe category, 50% are in the alert category and 8% are in the danger category, each of which has an effect on health. The system that was built can also send danger notifications via telegram

Abstract

The increase in internet usage in Indonesia has an impact in the form of potential cyber attacks such as malvertising, which is inserting malicious code or malware into advertisements when accessing the internet. In addition to malvertising, other malware activities are also detected in Badan Siber dan Sandi Negara (BSSN) malicious traffic monitoring system. The increase in internet access in Indonesia is also influenced by the growth of smartphone users who are always connected to the internet. The connection of digital devices such as smartphones requires testing of their activities. This study proposes testing the security of internet access on smartphones using the sandbox method. To facilitate testing, a cyberdeck-based mobile sandbox with integrated sensors was developed. The sensors used are malvertising sensors and anomalous traffic. Based on testing of mobile phone activity using the mobile sandbox, smartphones with the vanilla version of the Android operating system have fewer malvertising attacks than those operating systems that have been redeveloped by manufacturers. Although the malvertising attacks are the lowest, they have the potential for anomalous traffic caused by internet access by users or the installation of additional applications.
