<![CDATA[Safety is a top priority with the implementation of safety protocols, preparedness training, surveillance technology and early warning systems. A disaster is an event that causes loss, suffering and accidents in physical, economic, social and environmental forms. Common problems that often cause landslides are tree felling on slopes or due to unpredictable natural factors, resulting in landslides affecting settlements and causing fatalities. One solution to overcome this problem is to create an early detection tool for landslides with good and real-time communication to the internet. This tool is designed to facilitate monitoring of slopes that have the potential for landslides without having to go to the location directly. Research was conducted to determine the design and performance specifications of the tool.

This tool is designed to facilitate monitoring of slopes that have the potential for landslides without having to go to the location directly. Research was conducted to determine the design and performance specifications of the tool. The research results are in the form of performance specifications and design specifications.

<![CDATA[Housing is a fundamental human necessity that serves as a place for living, resting, and ensuring comfort and security. However, inefficient electricity consumption and inadequate security systems remain prevalent challenges in residential environments. This study aims to design and evaluate the performance of an Internet of Things-based smart home control system integrated with an Android application. The research adopts an engineering methodology consisting of system design, development, and experimental testing. The proposed system utilizes an ESP32 microcontroller, Passive Infrared sensor, Light Dependent Resistor sensor, and relay module, with an Android-based interface developed using MIT App Inventor and supported by Firebase for real-time data communication. The system has two modes: automated mode, which is powered by sensor inputs, and manual application mode, which is enabled by voice instructions. In automatic mode, lights are engaged when low ambient light and movements are detected, whereas in application mode, users can control illumination remotely via voice interaction. Experimental results show that the system achieves 100% accuracy and precision under the test conditions. These findings show that the suggested smart home system is extremely dependable and successful in optimising energy use and improving residential security.]]>

<![CDATA[In this ever-evolving digital age, the need for wireless communication technology is becoming increasingly crucial in various sectors, such as commercial, industrial, educational, and even household. One of the most commonly used wireless technologies is WiFi (Wireless Fidelity), which enables high-speed wireless internet connections and supports user mobility efficiently. To ensure optimal WiFi performance, a frequency filter capable of selectively operating at specific frequencies, such as the 2.4 GHz band, is required. This study aims to characterize a bandpass filter for 2.4 GHz WiFi applications. The bandpass filter design employs a parallel coupled lines structure. Simulation results show that the filter has a center frequency of 2.45 GHz with a return loss of −28.6 dB, insertion loss of −1.61 dB, and a bandwidth of 93 MHz, which aligns with the specifications. However, measurement results after fabrication showed differences, namely a center frequency of 2.47 GHz, return loss of −25.65 dB, insertion loss of −3.55 dB, and bandwidth of 93 MHz. In conclusion, although the simulation performance meets the specifications, the fabricated performance shows deviations that are likely caused by fabrication tolerances and imperfections in the fabrication process.]]>

<![CDATA[The rapidly developing digital era today, particularly advancements in technology within the fields of navigation and information. One such technological advancement is the Global Positioning System (GPS). GPS is a satellite-based system that uses microwave signals to continuously provide accurate information on position, speed, direction, and time, independent of time and weather conditions. As a result, to obtain accurate information, a device known as a lowpass filter is required to reduce interference in the GPS receiver signal. The increasing sophistication of technology has driven the need for more efficient systems. Therefore, filters for GPS receiver applications are generally designed to be small and thin. One such filter with these characteristics is the microstrip filter. This filter has several advantages, including its small size, ease of fabrication, simplicity in production, and ease of integration into other electronic devices. This research aims to analyze the effect of adding stubs, the influence of the filter's physical dimensions, and to characterize the lowpass filter for GPS applications. The filter was designed using a stepped impedance hairpin resonator (SIHR). The substrate used was NPCH-220A with a dielectric constant of 2.17 and a substrate thickness of 1.6 mm. The proposed design complies with the specified filter specifications. Simulation results show a cutoff frequency of 1.79 GHz, return loss of -24 dB, insertion loss in the passband of -0.1 dB, and at the cutoff frequency of -3 dB. Meanwhile, the measurement results show a cutoff frequency of 1.66 GHz, return loss of -45 dB, insertion loss in the passband of -1.6 dB, and at the cutoff frequency of -3 dB. From the results of this study, the microstrip lowpass filter using a stepped impedance hairpin resonator can be used in GPS applications.]]>

<![CDATA[The cultivation of Discus ornamental fish requires a stable aquarium environment, particularly in maintaining water quality parameters such as temperature, pH, turbidity, and feeding management. Irregularities in these parameters can lead to stress, disease, and even mortality in fish. This study aims to design and implement an Internet of Things (IoT)-based Smart Aquarium system capable of monitoring and automatically controlling water quality and feeding in real time. The research method used is an engineering approach with experimental testing. The system is built using an ESP32 microcontroller integrated with a DS18B20 temperature sensor, pH sensor, turbidity sensor, and HX711 load cell sensor. The actuators include water pumps, relays, a heater, and a servo motor, supported by float switches and a water level sensor for automatic draining and refilling processes. System data is displayed through an I2C LCD and the Blynk application via Wi-Fi for remote monitoring. The experimental results show that the system operates effectively with high accuracy, where the temperature sensor achieves 99.45% accuracy, the pH sensor 98.51%, the turbidity sensor 99.30%, and the load cell sensor 99.25%. The system is capable of maintaining water temperature within the range of 28–30°C, detecting unsuitable water conditions, and controlling feeding based on weight automatically. Therefore, the proposed Smart Aquarium system improves efficiency, monitoring convenience, and the overall quality of Discus fish cultivation.]]>
