Implementation of Ultrasonic Sensor in IoT-Based Water Volume Control and Flow Rate Reading System
type: item
description: This system designs a non-intrusive water flow rate reader and volume controller based on a clamp-on transit-time ultrasonic flow meter (V-mount, 4-inch pipe) using the TUF-2000M, integrated with an ESP32. The time-of-flight difference is converted into velocity, flow rate is calculated (Q = v·A), and volume is estimated through integration. The volume controller stops the flow precisely at set points of 2, 4, and 6 liters to minimize overshoot. The Blynk IoT platform provides a remote interface for set point selection and real-time monitoring (flow rate, velocity, fluid sound). Performance is evaluated based on volume error, set point achievement time, and repeatability, with quick installation and minimal pressure loss. The ESP32 microcontroller serves as the controller and data processor, supported by a relay module to control the solenoid valve's open or closed state. Testing results show a 4% error for 2 liters (within a 10% error limit), a 0.10% error for 4 liters (within a 10% error limit), and a 2.5% error for 6 liters (within a 10% error limit).

Evaluation Of The C4.5 Decision Tree and Random Forest Classification Algorithms in Predicting Diabetes
type: item
description: This study investigates diabetes prediction as a binary classification task using the C4.5 Decision Tree and Random Forest algorithms on the Pima Indians Diabetes dataset. The objective of this study is to compare the performance of both algorithms under three reported experimental settings: without data balancing, with data balancing, and with hyperparameter tuning without balancing. The dataset consists of 768 records, including 500 non-diabetes cases and 268 diabetes cases. The preprocessing stage included data cleaning, Box-Cox transformation, min-max normalization, feature selection, and data splitting into 80% training data and 20% test data. Model performance was evaluated using accuracy, precision, recall, and F1-score through 3-fold, 5-fold, and 9-fold cross validation. The results show that Random Forest consistently outperformed the C4.5 Decision Tree across all reported settings. Under the non-balancing condition, Random Forest achieved the highest accuracy of 77.82%, while C4.5 achieved 69.65%. After applying data balancing, the performance of both models improved, with Random Forest achieving the best overall reported accuracy of 84.19%, compared with 75.68% for C4.5. Under hyperparameter tuning without balancing, Random Forest achieved 78.18%, while C4.5 achieved 74.18%. These findings indicate that Random Forest is more robust and effective than the C4.5 Decision Tree for diabetes prediction, and that data balancing contributes more significantly to performance improvement than hyperparameter tuning alone.

Magnetic Tactile Display for Heartbeat Emulation
type: item
description: Recently, humanoid robots have developed rapidly and have the potential to become a medical innovation, enhancing human interaction. The ability to realistically mimic a heartbeat is a key feature under development. This research aims to design a ferrofluid-based magnetic tactile display to represent a heartbeat in a humanoid robot. This system utilizes an electromagnetic matrix, ferrofluid, and an Arduino Uno as a magnetic flield controller. Electrocardiogram (ECG) data is used to represent various heart rate patterns, such as normal, bradycardia, and tachycardia. The development results indicate that the magnetic tactile display is capable of providing tactile feedback that corresponds to the heart rate pattern. This device mimics heartbeats based on ECG data by controlling ferrofluid through magnetic field settings, allowing users to feel it tactilely. Testing using an accelerometer sensor shows that the system can replicate normal heartbeats and bradycardia with a small average time difference of 4.52% and 3.93%, respectively. However, in tachycardia, there were difficulties in handling rapid interval changes, resulting in a time error of 31.67%. The results of this study indicate that magnetic tactile displays have great potential in physiological emulation in humanoid robots.

Perencanaan dan Implementasi Sistem Pembangkit Listrik Tenaga Surya On-Grid pada Instalasi Pengolahan Air
type: item
description: This study aims to design and evaluate an on-grid Solar Power Generation System (PLTS) for the Water Treatment Plant (IPA) Taban III in Lubuk Minturun, Padang, addressing the lack of research on on-grid PLTS in government-operated water treatment facilities. Using an engineering design approach, the study covers energy load analysis, Helioscope simulation, and economic feasibility assessment. The site has an average daily solar irradiance of 4.91 kWh/m²/day. The total facility load is 34.32 kW (40,376.47 VA). The PLTS is designed to supply 20% of this, prioritizing a 2.3 kW active load with daily energy demand of 13.8 kWh. The proposed system consists of 27 monocrystalline solar panels (550 Wp) and a 20 kW three-phase grid-tied inverter. Simulation results show an annual energy output of 19,287.9 kWh and a Performance Ratio of 78.06%. The PLTS supplies approximately 59% of daily load demand, with the remaining 41% from the PLN grid via net metering. Deviation between manual calculations and simulation is below 0.5%. Total investment is IDR 239,250,476 with annual savings of IDR 23,419,400, yielding a payback period of approximately 10 years and 3 months. The system is feasible and supports national renewable energy targets, and is recommended for similar public utility facilities.

Performance Evaluation of Delay and Jitter in Optical Fiber Networks for Real-Time Multimedia Applications
type: item
description: The increasing reliance on real-time services such as VoIP and video streaming underscores the critical role of fiber optic networks as high-capacity communication backbones. While optical fibers offer substantial bandwidth, this alone does not ensure optimal Quality of Experience (QoE); network delay and jitter remain prominent challenges that can disrupt audio clarity and video continuity. This paper presents a detailed analysis of delay and jitter phenomena within fiber optic systems, particularly emphasizing Passive Optical Network (PON) topologies. It explores the underlying causes of performance degradation from physical-layer limitations to architectural inefficiencies and critically assesses current mitigation techniques implemented at both the network level (e.g., Quality of Service mechanisms) and application level (e.g., jitter buffering strategies). The main contribution of this work is the introduction of a novel "Cross-Layer Performance Optimization Framework," which addresses the disconnect between static QoS enforcement and reactive application adaptations. By fostering dynamic interaction between the network and application layers, this framework aims to enable predictive control mechanisms that better safeguard user experience. Ultimately, this approach offers a pathway to more robust and efficient delivery of real-time services over next-generation optical access networks.

Image Steganography: Digital Information Embedding Using Singular Value Decomposition and Simulation Software
type: item
description: Singular Value Decomposition (SVD) is a matrix decomposition technique that is widely used in digital signal and image processing because of its ability to represent important information efficiently. This study aims to explore the use of the SVD method in the steganography and watermarking process of digital images as part of efforts to improve the security of multimedia information. The approach used involves inserting hidden data in the form of images, sentences, and paragraphs into the host image by modifying the singular value elements of the image matrix decomposition results. Various scenarios are simulated, including inserting RGB format watermarks into grayscale images and vice versa, by testing variations in the insertion parameter (α). Evaluation is carried out on the visual quality of the resulting image (imperceptibility), as well as the success rate of information extraction. The experimental results show that this method can insert information without causing significant visual distortion and still maintain high message extraction accuracy. This study confirms the effectiveness and flexibility of the SVD technique as an information insertion method that can be applied in digital copyright protection systems and visual data security. This method also has the potential to be integrated with other techniques in more complex and robust watermarking systems.

Design and Implementation of a Vision-based Wheeled Mobile Robot Using HSV Color Segmentation and P-D Control
type: item
description: This study presents the design and implementation of a wheeled mobile robot capable of detecting and tracking a ping-pong ball using vision-based processing. The system integrates a Raspberry Pi 3 Model B+ as the main controller, a Raspberry Pi Camera Rev 1.3 for visual input, and DC motors driven by an L298N motor driver for actuation. Object detection is achieved through color segmentation in the HSV color space using the OpenCV library, followed by morphological filtering and contour analysis. A proportional-derivative (PD) control algorithm is employed to adjust motor speeds dynamically based on the ball's horizontal position in the frame. The experimental results demonstrate that the robot can successfully detect and follow a ping-pong ball, although it exhibits limitations in processing speed and motion stability. The average frame rate during operation was 5 FPS, which is sufficient for basic tracking tasks but suboptimal for high-speed applications. This project highlights the feasibility of vision based robotic systems for simple object tracking tasks.

Deep Learning-Based Brain Tumor Classification Using Convolutional Neural Network
type: item
description: An essential noninvasive medical diagnostic technique is magnetic resonance imaging (MRI), which is particularly useful for identifying brain cancers. While earlier algorithms proved effective on smaller MRI datasets, their performance suffered on bigger datasets. This study addresses the need for a swift and reliable brain tumor classification system capable of sustaining optimal performance across comprehensive MRI datasets. The convolutional neural network is implemented using the Keras library, incorporating the ResNet50 architecture as a pre-trained model. The ResNet50 model is fine-tuned for the specific brain tumor classification task, with a Global Average Pooling layer, dropout, and a final dense layer with softmax activation. Data augmentation techniques are employed to enhance the model’s robustness, including rotation, width and height shifts, and horizontal flips. The training process involves optimizing the model using the Adam optimizer with a learning rate of 0.0001. Early stopping, learning rate reduction on plateau, and model checkpointing are implemented as callbacks to ensure efficient training and prevent overfitting. The proposed model achieves a remarkable accuracy of 99.28 percent after 15 epochs. The classification task involves distinguishing among four classes: glioma, meningioma, pituitary, and no tumor.

Classification Of Multi-Class Face Expression Using Modification Of VGG-16 Model
type: item
description: In the era of modern technology, facial recognition has become an important application in various fields, such as security, education and health. One method used to recognize faces is a Convolutional Neural Network (CNN), specifically the VGG-16 architecture which is known for its consistent performance. But even though CNN can recognize faces, its accuracy in recognizing faces is inadequate. This research aims to increase the accuracy of facial expression classification so that it is more optimal by modifying the CNN VGG-16 architecture. This research uses GridSearch techniques, K-Fold Cross Validation, and utilizes multiple datasets. The dataset used consists of two image datasets, namely SMIC and SAMM facial-micro expressions, each of which has been normalized and converted to a grayscale scale measuring 48x48 pixels. The GridSearch process is applied to optimize parameters such as the number of filters, learning rate, dropout rate, activation function, and batch size. The K-Fold Cross Validation technique with five folds was used to ensure the generalization of the model to new data. The research results show that this modification is able to achieve validation accuracy of up to 98.31% in the training process, showing a significant improvement compared to the standard method. And showed an increase in accuracy in testing of 98.04% in research.

Performance Analysis of Deep Neural Network to Noisy Digit Dataset
type: item
description: This work investigates the impact of noise on model performance by training a neural network on a digit dataset with varying Signal-to-Noise Ratios (SNR) to assess its resilience and generalization ability. The experimental setup involved training the model on datasets with noise levels ranging from clean images to highly distorted ones (SNR 5%–25%), analyzing accuracy, mini-batch loss, and training time. Results indicate that while the model achieves high accuracy (96.88%) at mild noise levels (SNR 5%), performance declines significantly at higher noise levels, with accuracy dropping to 78.91% at SNR 25%. The analysis of mini-batch loss and training time reveals that noise slows convergence and increases computational complexity. The confusion matrix further confirms that while the model effectively distinguishes between classes, noise-induced misclassifications become more frequent at lower SNRs. These findings emphasize the importance of noise reduction techniques and data preprocessing to improve model robustness in real-world applications.

Pengukuran Backup Time Uninterruptible Power Supply Untuk Penentuan Kapasitas Baterai VRLA
type: item
description: A battery is a device that stores power in an Uninterruptible Power Supply (UPS) system. The most common type of UPS battery found today is Valve Regulated Lead Acid (VRLA). So that the UPS can work optimally according to its capacity and backup time, it is necessary to determine the battery capacity. In this research, the capacity of the VRLA battery on a particular UPS was determined based on direct testing and based on calculations. VRLA battery capacity calculations refer to the UPS and battery datasheet. The calculation stage starts from calculating the current and battery power used according to the load power absorbed by the UPS and referring to the table of constant current discharge and constant power discharge characteristics. Determining battery capacity based on testing is done by measuring the backup time of the UPS. The calculation results and test results directly show that there is a difference in backup time because the battery used is an old stock battery. The research results also prove that determining battery capacity by calculation can ensure that the battery capacity is more appropriate or not too large so it is more economical.

type: item
description: Mini-Hydro Power Plants (PLTM) are a renewable energy source with significant potential in Indonesia, yet their utilization remains under-utilized. This study aims to evaluate the effect of waterway materials on power efficiency at the Sion PLTM in North Sumatra. The goal is to optimize power efficiency by selecting waterway materials, as well as to provide knowledge and a template for future similar projects or studies. The evaluation was conducted by comparing three types of channel materials: Open Channel (open concrete channel), Glass Fiber Reinforced Plastic (GRP) pipe, and High-density Polyethylene (HDPE) pipe. This study measured and compared the head loss, power output, and power efficiency of each material. The calculations revealed the lowest head loss value for GRP pipe (1.17 m), followed by HDE pipe (2.34 m), and Open Channel (18.14 m). Meanwhile, the results of the comparison of the power produced, the highest power was obtained from GRP pipes (13,624.64 kW), followed by HDPE pipes (13,406.21 kW) and Open Channel (10,456.51 kW). In conclusion, GRP pipe material is the most optimal choice for improving power efficiency at PLTM Sion, supporting the enhanced utilization of renewable energy to replace fossil fuels.

type: item
description: This article presents Fourier Transform application to extract features of Phonocardiogram Signals into its frequency components. Data was taken from Physionet Dataset of Phonocardiogram which comprises of normal and abnormal heart condition. Raw data was preprocessed using time clipping of 2 seconds at certain area that contains less noise. A lowpass filter was applied to denoise the raw signals. Experiments show the PCG of normal hearts has a dominant frequency of 50Hz to 150Hz, with the subdominant frequencies of 450 Hz to 650 Hz. The subdominant frequency of the normal hearts sometimes show anomaly with more amplitude compared to the dominant frequency.
