Warehouse Quality Monitoring Information System (IS4AC) was developed to improve the monitoring of storage environmental conditions, especially related to temperature, humidity, and PH₃ levels, which have an impact on product quality. This study includes the collection of initial data from partners used for system design and modeling, followed by the development of a sensor-based application that allows real-time monitoring. The research methodology includes data collection, system design, application development, and testing and implementation in the laboratory and partner warehouse locations. The results of the study show that IS4AC is able to provide accurate and timely information, improve operational efficiency, and reduce the risk of product damage due to unmonitored environmental conditions. With this system, users can make better decisions in storage quality management. In conclusion, this study shows the significant potential of an automated monitoring system in improving warehouse management, as well as contributing to the development of adaptive technology in various industrial sectors.

With the rapid advancement of information technology, it does not necessarily correlate with an equally swift increase in students' interest in the learning experience. Students need proper guidance in the use of information technology to enhance their learning interest, and one type of technology that can be utilized is Augmented Reality (AR). By employing Augmented Reality, it is possible to boost students' interest in the learning experience. In this study, the Action Research (PTK) method is employed to assess students' learning interest using AR technology.The research reveals an improvement in students' scores in the first cycle, with the initial cumulative score of 35% increasing to 40%. Chemistry is chosen as the subject for this study because students tend to achieve lower scores when working on assignments or exams without the integration of information technology in the instructional media.The study emphasizes the significance of incorporating technology, particularly Augmented Reality, to elevate students' learning experiences. In an era marked by the swift evolution of information technology, this research aims to bridge the gap between technological progress and the enhancement of students' learning interests.

Bullying among students is increasingly prevalent, driven by various factors, including environmental influences and the impact of globalization. This issue poses significant challenges for teachers, who are often expected to monitor all students throughout the school day despite limited resources and time. The aim of this study is to explore effective strategies for preventing bullying in schools by integrating technological and creative approaches. The research employs a mixed-methods approach, combining quantitative analysis of bullying incidents with qualitative data from interviews and observations. The study focuses on the implementation of CCTV technology to enhance student behavior monitoring and prevent bullying incidents. Additionally, it investigates the use of arts-based activities as a means to help students channel excess energy into positive, creative outlets, thus reducing the likelihood of engaging in bullying behavior. The findings suggest that the combination of technological supervision and arts-based interventions significantly reduces the incidence of bullying in schools. The conclusion emphasizes the effectiveness of a holistic approach that incorporates both advanced monitoring tools and emotional support activities, highlighting the potential for these strategies to create a safer and more supportive school environment where students can thrive both emotionally and socially.

The use of blockchain as a supporting element in securing transactions is growing, as the presence of the blockchain system ensures enhanced security in the data transaction process. However, it should be noted that blockchain requires a more complex system for data verification. This complexity is not a concern when using paid blockchain services. However, when users aim to implement it privately, multiple nodes are needed for transaction verification. We present a proposed scheme for the use of multiple nodes utilizing Docker for transaction verification. This approach makes the costs more affordable and the maintenance easier.

Greenhouse microclimate conditions can change rapidly, making reactive control less effective in maintaining stable environmental conditions. Short-term forecasting can help anticipate these changes and support timely control decisions. This study presents a secondary analysis of previously reported experimental results from an Internet of Things (IoT)-based melon greenhouse to examine the relationship between forecasting accuracy, forecasting horizon, and operational control performance. The analysis compares persistence, standard Long Short-Term Memory (LSTM), and modified LSTM forecasting approaches and examines environmental and resource-use indicators under predictive control. At a 10-minute forecasting horizon, the modified LSTM achieved a temperature root mean square error (RMSE) of 0.50 °C and a relative humidity RMSE of 2.07%, representing reductions of 21.88% and 20.69%, respectively, compared with the standard LSTM. Temperature RMSE increased to 1.12 °C at a 30-minute horizon, indicating reduced prediction accuracy over the longer horizon. The reported predictive-control configuration was associated with a 45.61% reduction in daytime periods exceeding the 35 °C operational threshold and a 44.74% reduction in daily fan switching events. Reductions in water, electrical energy, nutrient stock, and labour consumption were also reported. These operational outcomes reflect the overall control configuration and cannot be attributed exclusively to the forecasting model. The analysis is limited by the unavailability of raw time-series data for independent validation and statistical significance testing. The findings highlight the importance of evaluating forecasting accuracy and horizon alongside operational control requirements in greenhouse management.
