Abstract

Modern agriculture is increasingly adopting technology to improve efficiency and productivity. This study proposes the development of a Multi-sensor-based Chili Plant Monitoring System integrated with Internet of Things (IoT) technology and accessed via a website. This study is designed to monitor important parameters such as temperature, soil moisture, and soil pH in real-time to improve the efficiency of agricultural management. This system uses a number of sensors placed around chili plants to measure environmental parameters accurately. The temperature sensor is used to monitor the temperature of the plant environment, while the soil moisture sensor monitors the level of soil moisture which is important for plant health. Thus, they can monitor the condition of their chili plants remotely and make more timely decisions. In addition, the system can provide automatic notifications to farmers via the website when environmental conditions reach a specified limit. For example, farmers can receive a notification if the temperature exceeds a threshold or if soil moisture drops below the desired level. This allows farmers to take preventive measures or make necessary adjustments quickly. This research makes an important contribution to the development of efficient and sustainable technology-based agriculture. The implementation of the Multi-sensor-Based Chili Plant Monitoring System accessed via this website allows farmers to better manage their agricultural land, increase yields, and optimize resource use.

Abstract

Solar Power Plant is a new renewable energy source that can be utilized and is very accessible because it uses sunlight as the main medium of generation. Sunlight is expected to shine on the solar panel with a breakthrough using an aluminum foil reflector. Aluminum foil that provides reflection of sunlight can increase the output efficiency of solar panels. To get the productivity of electricity generated by the panel, maximum sunlight is needed on the surface. Reflectors can increase the intensity of sunlight with less heat generated. By using aluminum foil, the sunlight will be directed to the solar panel thus increasing the output power produced. The angle and tilt of the reflector will be adjusted to the position of the solar panel. The reflection of the aluminum foil has an effect on the intensity of light received by the solar panel and an increase in output power of 2-5%.

Abstract

The cooling tower circulating pump circulates cooling water throughout the cooling system by controlling the rotation of the circulating pump using an inverter. The method in this research uses quantitative methods. The research aims to analyze two circulating pump units with and without inverter. The results of one year of research on circulation pumps without inverter consumed 48,180 kWh of electrical energy and circulation pumps with inverter consumed 31,083.4 kWh of electrical energy, the resulting electrical energy savings was 17,096.6 kWh at a cost of IDR 19,058,263.9. Using an inverter can save electric energy consumption because the speed of the circulation pump can be adjusted, which causes the output voltage to vary and not always remain constant at the maximum value, so the electric energy consumption is lower.

Abstract

Geothermal Power Plant (PLTP) is a renewable energy source that has great potential to meet electricity needs in a sustainable manner with low carbon emissions. This research aims to develop mathematical models and Matlab-based control systems to increase the power capacity of geothermal power plants. The system model includes reservoir dynamics, production wells, turbines, and generators with control using the PID (Proportional-Integral-Derivative) method. Simulations were conducted to test the system response to variations in electrical load, reservoir temperature, and operational disturbances. The simulation results show that the PID control successfully maintains the electrical power output to be close to the reference value with a fast response despite the presence of overshoot and initial oscillation. Adjustment of PID parameters is recommended to reduce overshoot and accelerate stabilisation of power output. This research contributes to the optimisation of geothermal power plant operation so as to improve efficiency and national energy security based on geothermal energy.

Abstract

This study explores the optimisation of light intensity on solar cells to improve their energy efficiency. With the increasing global demand for energy and environmental issues due to dependence on fossil fuels, renewable energy sources, particularly solar energy, have become important. However, the efficiency of solar cells remains a challenge, with typical commercial efficiency ranging from 15% to 22%. This research investigates the impact of light intensity on solar cell performance and identifies strategies to optimise it. Factors such as semiconductor material quality, panel angle and orientation, and external conditions like weather and pollution are considered. The study shows that optimising light intensity can significantly enhance the energy conversion efficiency of solar cells. Methods such as using mirrors to concentrate sunlight and adjusting panel positions are explored to maximise light intensity. These findings contribute to the development of more efficient solar cell technology, aiding the broader adoption of clean energy solutions.

Abstract

The electric power system is a primary need, both for daily life and for industrial life. The provision of stable and continuous electric power is an absolute requirement that must be met in meeting the need for electric power. The distribution system is the distribution of electrical energy from the substation to consumers. There are 2 (two) distribution systems, namely primary distribution and secondary distribution. Primary distribution, the distribution starts from the substation (secondary side of the power transformer) to the distribution substation (primary side of the distribution transformer) or from the substation directly to the 20kV medium voltage consumer. Power transformers are equipped with a grounding transformer that functions to obtain a neutral point from the power transformer. Before replacing the coil winding, measurements were taken using a TTR transformer turn ratio test (megger) measuring instrument. It can be concluded that the location of the damage is in the coil winding section. The results of the voltage measurements on the Primary Winding between phases R-S = 410 V, ST phase = 407 V and TR phase = 375V. and the Secondary voltage between phase and Neutral is RN = 221V, SN = 237V and TN = 222V. and the current in the Secondary winding between phases is R = 7.64A, S phase = 7.64A and T phase = 8.08A.

Abstract

Atik Bakery uses a power generation system to meet its operational energy needs, one of which comes from a generator unit that plays an important role in maintaining a stable power supply. One of the key components in generator operation is the excitation system that functions to regulate the generator output voltage. This study aims to evaluate the performance of the generator unit excitation system at Atik Bakery, by analyzing efficiency, voltage stability, and response to changes in load. The methods used include measuring the generator output voltage at various load conditions, as well as monitoring the parameters of the excitation system using measuring devices and data analysis. The results of the study indicate that the generator unit excitation system can maintain a stable output voltage under normal load conditions, but there is a decrease in performance at higher loads, which can affect the quality of power supply to the factory. This evaluation provides a basis for efforts to improve and enhance the performance of the excitation system to improve operational efficiency and stability at Atik Bakery.

Abstract

A potential avenue for the utilisation of solar energy is through the establishment of a PLTS (solar power plant). The present study employs an experimental approach in two distinct locations to ascertain the voltage and current of a battery that has been charged by a 20 Wp solar panel of polycrystalline type. Additionally, the temperature and humidity at each location are measured. The research location is situated in Kabung Village, within the administrative boundaries of Medan City. The research period spanned six days, from April 27 to May 3, 2025. A series of measurements were conducted over the course of the day, commencing at 09:00 WIB / 16:00 WIB. The data was collected at 10-minute intervals and comprised a combination of voltage, current, temperature, and humidity measurements. These measurements were obtained from two distinct locations within the city and the village. The mean battery charging time in Medan city is 6.50 hours, with a voltage of 12.26 volts, a current of 0.23 Ampere, a temperature of 33.14 °C and a humidity of 72.2%. In the context of Kabung village, the mean battery charging time was determined to be 6.50 hours, with a recorded voltage of 12.92 volts, a current of 0.60 Ampere, a temperature of 40.17 °C and a relative humidity of 63.3%. This study provides significant insights into the impact of geographic location on the performance of PLTS, particularly with regard to the optimal levels of sunlight absorption. Whilst the duration of battery recharge remains unaltered in this instance, the probability of attaining a greater quantity of electrical energy within a reduced timeframe is more probable in locales exhibiting elevated levels of sunlight, such as Kabung Village.
