Abstract

Earthquake is natural event due to release of energy suddenly from within that creates seismic waves. The vibrations are usually caused by movement of earth's plates. It cannot be predicted when they are coming. Therefore, need to build an early warning system. It is for anticipation of save the community when an earthquake occurs. It provides solutions to minimize the impact of earthquake events. This system uses accelerometer sensor and arduino nano as a main controller and it is accompanied by Blynk application. This works for sent notification via smartphone. This tool has been successfully designed with manual testing to be able to see the sensitivity of earthquake sensor made. Accelerometer sensor works is using Tilt Method. Accelerometer sensor will tilt on surface as parable of earthquake. Accelerometer sensor will send vibration signal when earthquake occurs. Signal processing is done by Arduino nano as the main controller in system. If the signal is received by sensor then value of earthquake will be displayed on LCD screen. Status of earthquake was separated into 4 levels such as standby, alert, dangerous, dangerous and dangerous. After earthquake value appears on the LCD screen and the status is known then buzzer will sound. It indicates that the earthquake warning alarm is properly functioning. Next, NodeMCU also sends information to Blynk application, which is used as a notification and monitoring of earthquake conditions. Buzzer will sound as a warning alarm to notify peoples to save themselves. This sensor has three output coordinate points, namely X, Y, Z, which have analog values ​​on Arduino Nano.

Abstract

Anomalies in the DC system, both in the rectifier and the battery, will occur sooner or later, and the cause is equipment age, maintenance, and fault. The purpose of this study was to determine the anomaly that occurred in the 110 VDC system at PT. PLN ULTG Binjai. The research method is to observe, examine and measure the DC system. The research was carried out at the Paya Geli Substation and Pangkalan Brandan Substation. From the results of the study, it was found that the anomaly that occurred in the 110 VDC system at ULTG Binjai was the final voltage per battery cell which was less than 1 volt, namely the battery cell numbers 1, 34 and 39 in the Payageli substation 2 bank battery. DC ground occurs in bank 1 at the Paya Geli substation with the negative side connected to ground, the positive side voltage to ground is 95.2 volts, while the voltage on the negative side to ground is 8.4 volts. The main fault (phase loss) anomaly at the Pangkalan Brandan substation was due to the burning of the input line in the rectifier control module, causing the rectifier to fail and the DC supply from the rectifier to be lost and temporarily supplied by the battery. Regular maintenance is required for reliability to avoid anomalies and immediately recondition if the battery capacity is less than 60% and the final voltage per battery cell is less than 1 volt.

Abstract

Control and monitoring systems in poultry farm cages are very necessary, especially for broiler farmers because the harvest process from growth to ready to harvest takes 30 to 35 days with a weight per tail between 1.5-2.0 kg. Important variables that are prioritized in broiler cages, namely temperature, humidity and lighting as well as the availability of feed and drinks on time, determine the quality and quantity of the broiler harvest. The solution to these problems requires a system that can work automatically with real-time monitoring features so that important variables in the chicken coop can be really well maintained. This research uses a combination of DHT11 temperature and humidity sensors, proximity sensors as sensors to check the availability of water and feed in containers, LDR light sensors and GY-302 Lux sensors, Real Time Clock timer modules to organize scheduling the availability of drinking water and chicken feed. These sensors will provide data to the ESP32 controller to control outputs such as heating and cooling and valves for opening and closing the stock of drinking water and feed. This system has also been integrated with the Internet of Things so that the condition of the chicken coop can be flexibly monitored remotely using a Smartphone or laptop utilizing the internet network. Based on the tests that have been carried out, it proves that the system has worked well in maintaining important variables in the chicken coop and has been well integrated based on the Internet of Things.

Abstract

Tilapia cultivation requires good management of water quality and proper feeding to ensure optimal fish growth. One of the main challenges in this process is maintaining the water pH level within ideal limits and providing feed according to the needs of the fish based on their size. In addition, limited access to electricity in some locations makes fish pond management less efficient. This study aims to design an automated water circulation system that is regulated based on the water pH level and automatic feeding according to the needs of the fish, by utilizing solar panels as a power source. This system uses a pH sensor to monitor water conditions in real time and regulate water circulation to maintain ideal pH levels. Feeding is regulated based on the size and number of fish to ensure optimal feed efficiency and fish growth. This system is powered by solar panel energy, so it can operate independently without relying on conventional electricity networks. Test results show that the system is able to maintain water pH stability and automate feeding with high accuracy, while utilizing renewable energy effectively. The use of solar panels not only reduces dependence on electricity, but also reduces operational costs and supports environmental sustainability. This system is expected to increase the efficiency and productivity of tilapia cultivation, especially in areas with limited access to electricity.
