Abstract

This paper proposes an application that was designed using MATLAB App Designer in the form of an analog and digital modulation simulator that can be used as a learning tools in telecommunications systems courses. Studying the modulation process is one of the core areas of knowledge in the telecommunications field. Modulation is the process of superimposing an information signal on a carrier signal to produce a modulated signal. Modulation can be divided into analog modulation and digital modulation. Analog modulation is modulation with an input signal in the form of an analog signal, while digital modulation has an input signal in the form of a binary or digital signal. The results of designing analog and digital modulation simulators can display simulations of AM, FM, PM, ASK, FSK, and PSK modulation in the form of information signals, carrier signals, and modulation signals, as well as BER and SNR results for digital modulation. The simulator can work properly and in accordance with the theoretical analysis of analog and digital modulation. The greater the SNR level, the more the modulation system performance increases, because the BER (Bit Error Rate) value becomes lower.

Abstract

This research aims to design and build a power generation system that utilizes heat from waste combustion using a Peltier thermoelectric module, test the effectiveness of converting heat energy into electricity, and analyze the effect of fuel type and cooling system on device performance. The prototype system uses 12 Peltier modules. In the initial test, the configuration of 2 modules was connected in parallel and 10 modules were connected in series using leaf fuel. Then the Peltier modules were arranged in a full series configuration. The initial test only produced a voltage of 8.1 V at a temperature difference of 80°C. This voltage is considered suboptimal, the system managed to produce a voltage of up to 30 V at a temperature difference of 104°C. This high voltage is then stabilized to 15 V using a linear regulator circuit IC 7815 assisted by a transistor and a 2N3055 capacitor, to maintain output stability before entering the solar charge controller (SCC). The SCC regulates the charging of a 12 V battery, which is then used to supply power to a 500 W inverter to power a 40 W AC lamp. The system is also equipped with an ESP32 microcontroller as a control center, as well as various sensors (current, voltage, temperature) and a 16x2 LCD to display data in real-time. This research shows that the system can efficiently generate electricity from waste incineration and has the potential to be implemented as a small-scale alternative energy solution at Politeknik Bosowa.

Abstract

The use of solar energy is increasingly important in addressing climate change. This study designed a real-time web-based solar panel performance monitoring system by monitoring voltage, temperature, and light intensity using Arduino Uno and ESP32 connected to Firebase. Testing was conducted for one day from 08.00-17.00 WITA. In the morning at 09.00, Panel 1 reached a maximum voltage of 22.43 V with a light intensity of 54,612.5 lux and a temperature of 38.4 ℃, while Panel 2 reached 21.67 V with an intensity of 54,612.5 lux and a temperature of 39 ℃, Entering the afternoon at 11.30, Panel 2 recorded the highest voltage of 22.82 V at an intensity of 54,612.5 lux and a temperature of 41 ℃, while Panel 1 showed a voltage of 22.6 V with the same light conditions and a temperature of 39.7 ℃. In the afternoon at 5:00 PM, both panels experienced a significant decrease, where Panel 1 dropped to 8.33 V with an intensity of 13,865 lux and a temperature of 28 ℃, while Panel 2 dropped to 8.45 V with an intensity of 10,918.3 lux and a temperature of 28 ℃. It can be concluded that high light is indeed important in producing electrical energy in solar panels but is not enough if it is not balanced with a relatively low temperature. Optimal conditions are achieved when maximum light is accompanied by a temperature that is not too high, with panel 2 showing slightly more stable performance than panel 1.

Abstract

The coastal waters of Parepare City are surrounded by numerous food stalls whose wastewater and food residues are often discharged directly into the marine environment, leading to seawater pollution. Continuous monitoring is therefore required to assess water quality and support effective environmental management. This study aims to develop an Internet of Things (IoT)-based web server system for monitoring the seawater pollution index in the coastal waters of Parepare City. The research adopts a quantitative Research and Development (R&D) approach by integrating pH, turbidity, and Total Dissolved Solids (TDS) sensors to collect real-time water quality data. Sensor readings are transmitted to an IoT-based web server and processed to calculate the Water Pollution Index (WPI). Experimental results demonstrate that the system operates effectively under field conditions. Morning measurements produced a pH value of 6.9, turbidity of 2443 NTU, and TDS of 1179.1 ppm, resulting in a pollution index of 1.91, classified as lightly polluted. Afternoon measurements indicated a pollution index of 2.04 with increased turbidity, which also falls within the lightly polluted category. The proposed system provides a reliable solution for real-time monitoring of seawater quality in the coastal waters of Parepare City.

Abstract

Electric power generation is an important factor in an electrical system. The electrical energy that been generated, it would be distributed to consumers, both medium voltage and low voltage consumers. Before being distributed, the energy would be directed to substations to be managed and regulated by being increased, decreased, or divided. In substations, there were several protective devices that had function to protect equipment in the event of a disturbance, one of these devices is the PMS or disconnecting switch. This busbar disconnecting switch or PMS secured the system by separating the system from disturbances detection in the busbar. As the other electrical equipment, protective devices that have been used for a long time, it would lead to malfunction and decreasing of work. Therefore, this study focused on the condition of PMS that has been used for a long time, so this case could affect its temperature and performance. The researchers used a field study method for solving the problem. The result of this research showed that the long-term use of PMS could have an impact on decreasing performance and indicate the presence of hotspots and contact resistance exceeding the applicable standards.

Abstract

Variability is the ability of a software system or artifact to be changed, adapted, or configured for reuse in SPLE products. As the amount of variability increases in SPLE, the complexity of managing changes and the evolution of that variability becomes a primary concern of this case study. Software designers seek simple and specialized methods in designing software to make it easily understood and implemented in its development, especially in large-scale productivity design. This study uses the Orthogonal Variability Model (OVM) and the Cardinality-based Feature Model (CBFM) for the analysis and design of the MANRE.ID application system and identifies the basic requirements for building the MANRE.ID application and then uses OVM to establish relationships and identify them with each other. In this study, the researchers propose that the integration of models between CBFM and OVM results in easier and more structured development of MANRE.ID.

Abstract

Three-phase induction motors are widely used as primary driving machines in industrial applications due to their simple construction, high efficiency, and relatively low maintenance requirements. However, three-phase induction motors are susceptible to various faults, such as overcurrent, overvoltage, undervoltage, phase loss, phase reversal, and overtemperature, which may cause severe damage to the motor. This study aims to design and develop a PLC-based protection system for a three-phase induction motor using the Mitsubishi FX3U-14MR PLC as the main controller, the EOCR-DS3 as the overcurrent protection device, the CHINT XJ3-D as the voltage and phase protection relay, and the REX-C100 Temperature Controller for motor temperature monitoring.The research employed an experimental method involving the design of a control panel, integration of protection devices, PLC programming, and system testing under various fault conditions. The overvoltage test results showed that the protection relay generated a trip signal when the average three-phase (R-S-T) voltage reached 402 V with the overvoltage setting adjusted to 400 V. The relay also generated a trip signal when the average three-phase voltage reached 403 V with the overvoltage setting adjusted to 415 V. In the undervoltage tests, the relay generated a trip signal when the three-phase voltage dropped to 372 V with the undervoltage setting at 380 V, and when the voltage decreased to 359 V with the undervoltage setting at 360 V. The phase loss tests on phases R, S, and T demonstrated that the protection relay successfully detected the loss of each phase based on the measured voltage conditions. The test results indicate that all protection devices and sensors operated properly and successfully detected fault conditions according to the predetermined settings. Therefore, the proposed three-phase induction motor protection system based on PLC was proven to function effectively and can improve the reliability and operational safety of the motor

Abstract

Public Street Lighting (PSL) plays an important role in supporting safety, security, and comfort for road users. Therefore, an effective monitoring and control system is required to improve energy efficiency and facilitate lamp condition monitoring. This study aims to design and develop a street lighting monitoring and control system based on many-to-one and one-to-many communication using the NRF24L01 PA LNA module. The system consists of one master node and five slave nodes equipped with Photodiode sensors to detect ambient light intensity and BH1750 sensors to monitor lamp conditions. This research employed an applied research method with an experimental approach through system design, implementation, and testing. The results showed that the system successfully performed data communication between the master node and slave nodes effectively. The BH1750 sensor achieved an average error of 7.27% with an accuracy of 92.73%, while the Photodiode sensor was able to detect changes in ambient light intensity effectively. The NRF24L01 PA LNA module achieved a communication range of up to 103 meters with delays ranging from 2.41 ms to 20.42 ms. The system was also capable of real-time lamp condition monitoring and both automatic and manual lamp control. Based on the test results, the proposed system operated according to the research objectives and is feasible to be implemented as an efficient and centralized street lighting monitoring and control solution

Abstract

Paddy is one of the agricultural commodities that requires a drying process to reduce water content so that the quality of the paddy is maintained and ready for milling. The traditional drying process still depends on weather conditions so it takes a relatively long time and is less efficient. This study aims to design and test a microcontroller-based rotary type paddy dryer prototype that is able to control the drying process automatically based on weight and temperature parameters. The system uses Arduino as the main controller, a DHT22 sensor to measure temperature, a load cell sensor and an HX711 module to measure the weight of the paddy, and a DC motor and blower as actuators. Tests were carried out on the sensor, temperature control system, and the overall performance of the tool. The results of 10 load cell tests showed an average error in measuring the initial weight of 0.762% and the final weight of 0.453%. The weight loss of unhusked rice during the drying process ranged from 17 to 75 grams, with an average weight loss percentage of 9.66%, approaching the target weight loss of 10%. Testing the DHT22 sensor against a reference temperature sensor resulted in an average error of 1.97%, with a reading difference of 0.3 to 1.0°C. In the overall test, the weight of unhusked rice decreased from 229 to 407 grams to 204 to 362 grams, with a drying time of 5 to 23 minutes and a drying temperature of 41.8 to 47.2°C. These results indicate that the prototype is capable of automatically carrying out the drying process, controlling the temperature, and detecting changes in unhusked rice weight. Thus, the designed prototype can be used as an alternative to a more controlled and efficient small-scale unhusked rice drying system.
