Abstract

A sprayer machine that can reduce air pollution and is environmentally friendly by utilizing natural energy, namely sunlight, so that this tool can be used for spraying in plantations by utilizing solar energy sources. In addition to making work easier and faster, the required energy source is also not difficult to obtain, making it more effective and efficient. In the making of such a tool/machine, it is capable of working optimally. In designing the pest sprayer tool, the author uses a 20 wp solar panel which can generate an average daily power (P) of 30.03 watts. A battery with a capacity of 12 volts 7.2 Ah can supply an average power (P) to a 12 volt 3 Ampere DC motor of 9.40 watts when operating. The average power used per hour during the 6-day testing period is 9.40 watts. The time required for the battery to be charged by the solar panel depends on the weather conditions and the intensity of light at the operating location because it affects the high and low current received. The power used to spray pesticide fluid from the tank until it runs out is: 1.6760 Watt.

Abstract

This research focuses on modeling and simulating temperature and pressure parameter settings in geothermal power plants using MATLAB software. Geothermal power plants utilize geothermal heat as an energy source to produce electricity, so controlling temperature and pressure parameters is a key factor in optimizing system performance. The method used in this research includes developing a mathematical model of a geothermal power generation system, followed by numerical simulations to evaluate the dynamic response to variations in operational parameters. Simulation results show that proper regulation of temperature and pressure can increase plant efficiency and operational stability. In addition, this study also explores the influence of various parameter setting scenarios on the power output and energy consumption of the system. Implementation of the model in MATLAB makes it easy to visualize and analyze data, and allows real-time simulations needed for fast and accurate decision making. In conclusion, this research succeeded in showing that modeling and simulation using MATLAB is an effective tool for optimizing temperature and pressure parameter settings in geothermal power plants, which in turn can increase overall system efficiency and reliability.

Abstract

The application of solar-based water pump technology in Desa Besar II, Pantai Cermin District, Serdang Bedagai Regency, aims to overcome the irrigation challenges faced by local farmers. This village, which is an agricultural area with great agricultural potential, has experienced a decline in crop yields due to inadequate traditional irrigation systems, especially during the dry season. The application of solar water pump technology is expected to increase irrigation efficiency by utilizing solar energy as a clean and sustainable source of energy. The implementation of this activity includes the installation of a solar water pump system, intensive training for farmer groups on the operation and maintenance of the system, and monitoring and evaluation to assess the effectiveness of the technology. The evaluation results showed an increase in crop yields of 20-30% and improved crop quality, thanks to more consistent irrigation. Positive responses from farmers regarding the ease of use of the technology and the training provided also reflect a significant impact on their independence and welfare. Recommendations for further development include the expansion of this technology and increased technical support in the future.

Abstract

Di era yang sudah serba digital kebutuhan untuk melakukan promosi di media massa khususnya elektronik (dalam bentuk iklan di televisi) sudah merupakan suatu hal yang lumrah dilakukan, dengan tujuan untuk menarik minat orang banyak terhadap apa yang dipromosikan tersebut. Namun demikian tetap saja ada yang menggunakan papan-papan reklame (Billboard) yang terletak ditempat-tempat tertentu saja dan mungkin posisinya ada yang tidak pas dengan sudut pandang penglihatan atau dengan kata lain hanya dari posisi tertentu saja untuk dapat melihat isi informasi papan reklame tersebut. Untuk mengatasi masalah tersebut dibutuhkan suatu papan reklame yang dapat berputar dan dengan menggunakan sebuah Microcontroller AT89S51 dan sebuah motor Stepper, akan dirancang suatu model papan reklame yang dapat berputar tetapi hanya dalam bentuk miniatur.

Abstract

Traffic congestion in areas with two closely situated traffic lights is a complex issue that is often difficult to resolve. To address this issue, a coordination of timing between the two traffic controllers is proposed. This research conducts an experiment with two traffic controllers at two nearby intersections. The vehicle flow at each intersection is managed by the Agent acting as the traffic controller. The agent where more vehicles arrive is designated as the master agent, while the other agent is designated as the slave agent. A coordination algorithm is developed to synchronize the timing of the traffic controller so that the timing at the slave Agent was adjusted according to vehicle platoon arrivals from the master Agent. By this method, the green phase of the slave agent can be synchronized with the master agent, allowing vehicle platoons arriving from the master agent to immediately receive a green phase at the slave agent. This coordinated traffic control can be implemented with a microcontroller-based system, and vehicle movement can be simulated using Matlab's SimEvents. From the experiment conducted for two intersections located 500 meters apart, this scheme can reduce the average vehicle wait time from 40 seconds to just 9.4 seconds.

Abstract

The electricity payment system in Indonesia is by calculating the power used. The tool that records the use of electrical energy is a KWH meter. From this problem, an idea was obtained to record the KWH meter digitally so that we can easily find out how much electricity is used. This tool provides a value every time a pulse is detected by a photo diode against the KWH disc movement indicator. The function of this tool is a simulation with assumptions based on the KWH meter disc movement indicator detected by the photo diode, after which the pulses are processed on the AT89S51 microcontroller, and presented via a seven segment display. So that customers can easily find out the cost of electricity that has been used. Overall tool testing is done by connecting all parts of the tool and the KWH Meter is connected to the power grid and to the load. Simple testing is done by connecting the tool to a load of 100 watts and 200 watts

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.
