Abstract

Many people in Indonesia keep freshwater ornamental fish, including guppy fish (Poecilia reticulata), green growth fish (Gyrinocheilus aymonieri), neon tetra fish (Paracheirodon innesi). Neon tetra fish are popular because of their distinctive striking and bright body lines, while guppy fish are kept because of their ease of care and beautiful color variations, especially in male guppies. Guppy fish can grow well at temperatures of 22°C - 27°C and pH 6.5-7.2. Because managers are busy, this becomes an obstacle in fish cultivation, because the water quality that determines fish development becomes unstable. The results of the PLTS output test for 7 days 7 hours per day from 09.00 – 15.00 WIB can charge the battery with an average voltage of 13.89 V and an average current of 1.2 A and an average power of 14.15 W and can run for 24 hours. O'clock. Testing the battery for 7 days and 7 hours from 09.00 – 15.00 WIB can meet power needs for 24 hours with an average battery voltage of 13.36 V and an average current of 0.71 A. Meanwhile, the test results for the servo motor with a feed weight of 2, 45 grams and a servo motor delay of 2 seconds.

Abstract

In new renewable energy, the abundant potential of solar energy in Indonesia needs to be utilized effectively, especially in vocational canteens for the purposes of lights and fans. This research aims to design and build an off-grid solar power generation system and Node-Red-based monitoring at the Canteen. The research method used is experimentation through direct observation at the vocational canteen. The tests carried out are the system of SPGS which includes voltage, current, and power and testing monitoring by system sensors and temperature sensors for 5 hours per day in two days. The results obtained are the voltage in the system both panel voltage, AC voltage, and battery voltage are stable and do not exceed the specifications of solar panels. However, the current has increased and decreased although not too drastically and the battery has only decreased by 10%. This is due to the influence of the weather during testing and is not affected by the load power because it does not exceed specifications. In addition, the system sensor has an error of no more than 2% so it can be said that if this system functions optimally and as expected, it can be developed more to save energy.

Abstract

Indonesia, as an agricultural country, faces the challenge of pests in the agricultural sector, one of which is the sparrow that often attacks rice plants, causing a decrease in rice yields. The use of traditional methods such as canned sound is considered less effective, so ultrasonic technology is chosen as a safer alternative to pesticides that can cause side effects to the environment. This research aims to design and test a sparrow and locust pest repellent tool on rice plants using ultrasonic waves based on LoRa technology, with the hope of offering a more efficient and environmentally friendly solution. Tests were conducted to determine the effectiveness of ultrasonic frequencies against sparrow and locust pests, as well as the maximum distance the tool can work. The device was tested with various wave frequencies (30 kHz, 35 kHz, 40 kHz) at different distances, and the LoRa communication range was measured until the signal was lost. The test results show that the optimal frequency to repel sparrows and locusts is 40 kHz with an effective range of up to 3 meters, and the LoRa module is able to transmit signals up to a distance of 63 meters. This research offers an alternative solution for farmers to repel pests effectively without harmful chemicals, as well as providing ease of tool control in areas without internet connection.

Abstract

In order to utilize the potential of solar energy and support the government in its energy transition efforts and achieve Net Zero Emissions, it is necessary to utilize solar power plants more massively. One thing that can be done is the installation of solar panels on the roof of a building called Rooftop PLTS. This rooftop PLTS is designed on the roof of the K4 Unesa building with an ongrid system because lecture activities only exist from morning to evening. Research conducted to analyze the potential of electrical energy on the roof of the K4 building using OpenSolar software. From the simulation results, the roof of the K4 building can be designed to install 70 solar panels with the LR4-72HPH-450M type and 5 Goodwe GW5K-DT type inverters which can produce 35,478 kWh per year with a PLTS capacity of 31,500 Wp. From the shadow simulation results, it is found that the selected location is optimal because there are no shadows of other buildings, trees or shadows from the solar panels themselves. Then from the POA analysis, it is found that between April to September has a relatively large amount of generation while in February the lowest energy is generated.

Abstract

The unwise use of electrical energy in households can lead to energy wastage and pose risks such as short circuits, which may result in fires. This research developed a Node-Red-based protection system using an ESP8266 microcontroller and a PZEM 004-T sensor to detect voltage, current, and power in real-time. The system automatically disconnects the current when overload conditions are detected, especially on extension cables. Testing was conducted on household devices such as laptop chargers, fans, and soldering irons. Results demonstrate that the system can accurately monitor current and power, maintain electrical stability, and cut off electricity when the load exceeds the safe threshold, thus reducing fire risk. This implementation is expected to enhance household electrical safety and serve as a reference for further development in IoT-based protection systems.

Abstract

The rapid advancement of technology has led to an increasing demand for electrical energy. One of the efforts to meet this demand is the development of micro-capacity power generation systems utilizing heat energy. Heat energy can be harnessed using thermoelectric elements. This study aims to design and develop a portable power generation system that utilizes solar heat as an energy source. The prototype uses six TEC 1-12706 thermoelectric modules to generate electricity designed specifically to recharge devices such as phones, power banks, and flashlights. Solar heat is concentrated on the thermoelectric modules using Fresnel lenses, while heatsinks are employed for cooling. The thermoelectric modules are connected in series to produce sufficient voltage, which is then boosted by a boost converter. The generated electrical energy is stored in a battery to ensure voltage stability despite temperature fluctuations. This device can also operate at night due to the energy stored in the battery. Test results show that the average output voltage without load ranges from 9.49V to 9.56V, with an average temperature of 45.2°C at the thermoelectric modules. In load tests, the device successfully charged a Pixel 5 phone (5000 mAh battery) from 4% to 70% in 95 minutes. These results demonstrate the potential of this system as a reliable and environmentally friendly portable energy solution.
