The integration of technology in livestock farming is crucial for enhancing production efficiency and animal welfare. This study aimed to develop and evaluate the implementation of a Narrowband IoT (NB-IoT)-based automated monitoring system in poultry farming. Using an experimental design, the research involved 30,000 day-old chicks at PT. Anugerah Teknologi Ternak in Central Java, Indonesia. The NB-IoT system collected real-time data on environmental parameters and poultry activity. Time-series analysis revealed non-stationary data, while correlation analysis showed a strong negative relationship between temperature and humidity (r = -0.8521). Anomaly detection identified 13.33% of observations as anomalous, demonstrating the system's capability for early issue detection. Regression modeling (R-squared = 0.7261) indicated that temperature and humidity significantly influence poultry productivity. The study concludes that NB-IoT implementation in poultry farming has significant potential for enhancing productivity through real-time monitoring and early anomaly detection, supporting more efficient and sustainable precision farming practices. However, limitations in data stationarity and sample generalizability suggest the need for further research to improve long-term predictions and broaden applicability across diverse farming contexts.

This research evaluates the performance of integrating Wazuh, an open-source Security Information and Event Management (SIEM) platform, with Grafana, a real-time visualization tool, for cyber threat detection in resource-constrained environments. The objective is to assess detection accuracy, false positive rates, response times, and system efficiency under controlled experimental conditions. The testbed consisted of two virtual private servers (4 vCPUs, 4–8 GB RAM, 38–50 GB storage) and employed the CIC-IDS2017 dataset as a benchmark for simulating three representative attacks: brute-force, malware injection, and webshell exploitation. The results showed that the integrated system achieved 100% detection accuracy with 0% false positives across 30 trials, with an average total detection time of 3033 ms. Resource utilization remained low, with CPU usage below 35% and memory consumption under 25%, confirming feasibility for mid-range servers typical of small institutions. While these results underscore the system’s efficiency, the findings must be interpreted within the limitations of a laboratory environment where predefined signatures were used. Performance in real-world networks with diverse traffic and unknown threats may differ, and further validation is required. This study makes two key contributions: (1) it provides the first structured quantitative benchmark of Wazuh-Grafana integration in constrained environments using a standardized dataset, and (2) it offers practical recommendations for small and medium-sized institutions, including minimum system requirements and guidelines for dashboard configuration. These findings reinforce the role of open-source solutions as affordable, adaptive, and effective alternatives to commercial SIEM systems, particularly for organizations with limited cybersecurity budgets.

Server computers generally work 24 hours and continuously. The tasks of the server, starting from running the operating system, applications, and data storage, are heavy and oversized. All electronic devices inside the server generate heat when operating. If they are not conditioned in a room with low temperatures, then the temperature of the server computer will increase and cause a decrease in the performance of the server. This study tested the temperature sensor available from the Application Programming Interface (API) feature from Tuya. Utilizing the API will facilitate the design of a system that can focus more on monitoring application development because the built system is no longer focused on complicated and risky hardware designs. The results of monitoring the server room's temperature can be monitored with sensors integrated with Tuya on a web-based page
