Abstract

Biogas, an eco-friendly energy source, significantly reduces greenhouse gas emissions by converting organic waste or biomass into methane. However, the quality of biogas, primarily determined by methane content and pressure variables, directly impacts its efficiency and safety. This study, which aims to design a pressure control system and monitor methane gas levels in a biogas reactor using a PID Controller with Particle Swarm Optimization (PSO), provides crucial insights into improving biogas production efficiency and safety. Tests were conducted on a fixed dome-type biogas reactor in the East Java region, Indonesia. The PSO-based PID tuning was compared with two other PID tuning methods: Trial-error and Ziegler-Nichols (ZN). Data on pressure values and biogas flow rates from the biogas reactor were collected, and system modeling was carried out to produce a system transfer function. The PSO algorithm was developed to optimize PID control parameters. The results of this research demonstrate that the PID tuning method using PSO produces a stable state error value of 1.40%, rise time of 0.09 s, settling time of 2.1 s, maximum overshoot of 0.986404, and ITAE of 0.0010801. The implementation of PID-PSO can significantly enhance PID control performance in rise time, settling time, maximum overshoot, and ITAE compared to Trial-Error and ZN, while the stable state error value in PID-PSO tuning is higher than tuning using Trial-Error and ZN.

Abstract

Developing renewable energy is one of the main strategies to reduce greenhouse gas emissions and achieve global goals to limit global warming above pre-industrial temperatures. This study analyzes the effect of varying the cooling water flow rate on MS100-36 type polycrystalline photovoltaic modules through ANSYS Fluent 2024 R1 Student simulation. This simulation was conducted from 08:00 to 17:00, focusing on the influence of inlet water temperature on the temperature distribution of photovoltaic modules. The simulation results indicate thermal steady-state conditions at an irradiation of 463 W/m² with a natural coefficient of 5 W/m².There is a temperature distribution process occurring in the photovoltaic module under fluent conditions, where the effect of the inlet water temperature on the surface of the PV module is examined for a water temperature range of 20°C to 30°C in 5°C intervals, with water flow rates of 0.05, 0.1, and 0.2 kg/s. The contour images indicate that an increase in water flow rate can enhance the cooling effect of the photovoltaic module. Higher inlet water temperatures transfer less heat, producing higher temperatures for the photovoltaic modules. A water flow rate of 0.2 kg/s and an inlet water temperature of 20°C produce a lower and more uniform temperature distribution on the photovoltaic modules. Thus, increasing the water flow rate and decreasing the inlet water temperature have proven effective in enhancing the cooling performance of photovoltaic modules.

Abstract

The wrist is essential to various human activities, with basic flexion, extension, and straight (normal) movements. These movements can be identified using surface electromyography (sEMG) signals that allow human interaction with computers through muscle activity, referred to as a muscle-computer interface. This research aims to perform the classification of flexion, extension, and normal movements as an initial stage of developing a muscle-computer interface system. The main stages of this research include data acquisition, signal processing, and motion classification with a support vector machine (SVM) offline and not in real-time, using root mean square (RMS) features with a moving window. This study successfully designed an effective sEMG signal measurement and processing method for motion classification. The designed classification algorithm showed high performance with an accuracy of 90.27%, precision of 90.61%, sensitivity of 90.17%, and f1-score of 90.27%, demonstrating the ability of the muscle-computer interface to classify wrist movements with a high degree of accuracy.

Abstract

One of the main challenges in farming activities is regarding efforts to detect and monitor pests, which can be used as a basis for determining correct pest control efforts. Greenhouse whitefish (GWF) is a dangerous pest that absorbs plant sap, causing plants to weaken or even die due to lack of nutrition. Efforts to detect GWF pests are generally carried out manually using yellow sticky traps (YST), which require routine and repeated checking efforts from farmers with a long time interval between each checking activity. This research is aimed to design an automatic monitoring solution of GWF pests based on the camera image of YST paper. The proposed design method uses a web-based wireless sensor network system equipped with image processing algorithms that operate in a real-time manner. In the proposed method, the camera sensor is used to capture YST images, which are then processed using a website-based application system. The evaluation of the prototype testing suggests that the designed pest detection system functions well and without problems. With regard to the developed hardware, evaluation results show that the camera sensor can be accessed and send data to the developed website application in a real-time manner. Regarding the image processing algorithm, evaluation results show that the developed histogram based image processing technique can detect GWF on plant leaf being considered with accuracy levels up to a range of 94%-100%.

Abstract

The rapid growth of four-wheeled vehicles in Indonesia has contributed to an increase in traffic accidents, where human error is a significant factor. Adaptive Cruise Control (ACC) is a technology that has been widely implemented in Advanced Driver Assistance Systems (ADAS) to improve driving safety. This study develops a Fuzzy Logic Controller (FLC)-based ACC system using ESP8266 as the main microcontroller to optimize adaptive vehicle speed control based on the distance to the object in front. This system is designed to process distance and speed data in real-time, allowing it to adjust the vehicle's speed without sudden changes. A fuzzy logic model was developed and validated through MATLAB simulations before being implemented into hardware. Test results indicate that the FLC-based ACC system can maintain a safe distance and dynamically regulate speed, exhibiting smoother speed transitions compared to conventional methods. A comparison between MATLAB simulation results and real-world implementations shows that the system can operate with high accuracy, despite differences due to environmental factors. With this success, this research proves that FLC can be a more flexible alternative in ACC systems and has the potential to be applied in the development of electric and autonomous vehicles in the future.

Abstract

The rapid development of technology allows human work to be replaced by robot technology. The most frequently used robot in industry is the robot arm. The robot arm can imitate the human arm's characteristics, so it is often used to help humans lift and move goods. With this principle, the robot arm can be used as a weight-lifting robot to aid in calibrating electronic scales. This paper analyzes the control of the DC motor on a weighing-scale lifting robot arm by optimizing the overshoot with PID (Proportional - Integral - Derivative) control. The PID Control test results on the DC motor rotation are stable at 100 rpm with a steady state error of 0%. The system's response to the DC motor has a settling time of 1,26 s and an overshoot of 2%.

Abstract

Generally, the operation of lights and Air Conditioners (AC) in a room is still done manually and is not adjusted to actual needs or conditions. This can cause a waste of electrical energy, which increases electricity costs. This research aims to design a room light and temperature control system to optimize the operation of lights and air conditioners in accordance with SNI 6197:2011 concerning lighting standards and SNI T-14-1993-037 concerning thermal standards. The operation of the lamp is based on three light conditions, namely, dark, medium, and bright. The operation of the AC with three membership sets of temperature, namely, down, medium, and up, is the result of processing the Sugeno fuzzy logic method based on three membership sets of room temperature, namely, cold, normal, and hot, and also based on three membership sets of the number of people, namely, few, medium, and many. This system consists of an SHT20 temperature sensor, TSL2561 light sensor, HC-SR501 motion sensor, E3JK-S4M2 photoelectric sensor, and PZEM-004T electrical sensor as well as ESP32 microcontroller as the controller of TL light actuator and air conditioners actuator. The results of testing for two days at the PPNS Robotics and Artificial Intelligence Laboratory show that the designed system can reduce the use of electrical energy by 14.2 kWh, equivalent to Rp.7.512,44,- from 32.5 kWh, equivalent to Rp.33,950,- to 18.3 kWh, equivalent to Rp.26,438,-.

Abstract

Elderly-supporting technology is a continuously evolving field as new needs emerge and novel solutions are developed. This work addresses the challenge elderly individuals face in picking up objects from the floor, a task often painful or difficult for those with back pain. Currently, no such assistive system is available on the market. This study aimed to develop a crane claw-integrated walking stick that enables object retrieval without bending, enhancing mobility and reducing fall risks. By integrating the claw with the walking stick, the design eliminates the need for an additional tool. Three design concepts, using repurposed 3D printer parts, were evaluated for performance, simplicity, and cost, resulting in the selection of a cable winch mechanism. Stress and fatigue analyses using SolidWorks ensured safety; the claw assembly exhibited a maximum stress of 7.238×10⁶ Pa, a safety factor of 4.8, and a fatigue life of 691,507 cycles. The product was fabricated from PLA with 50% infill and a tri-hexagonal pattern. A mechatronics system—comprising an Arduino UNO, DC motor, H-Bridge L298N module, and sensors—enabled precise control of the claw mechanism. The final device promotes independence and mobility for elderly users, offering a practical, ergonomic, and user-friendly solution.
