Abstract

Image segmentation is very important in the approach of image analysis to learn about any image. The K-means clustering technique is an algorithm widely used in image segmentation systems. This work utilizes the Lab* color space and K-means clustering to offer color-based image segmentation. This research demonstrates image segmentation of a database based on color characteristics using unsupervised K-means clustering technique implemented with MATLAB coding. The entire work is divided into two phases. Firstly, color separation augmentation from the color image database is enhanced through de-correlation stretching. Then, the six areas of the image database are clustered into three groups using the K-means clustering technique. By using the Lab* color space and K-means clustering method in the color image database, we can only show the central area of any image. We can isolate contaminated areas in medical color image databases with this approach and treat diseases quickly. We can use various approaches such as Particle swarm Optimization (PSO) for better results.

Abstract

Landslide catastrophes are one of the disasters that frequently occur in Indonesia owing to the weather and climatic features, regional terrain, and geological formations that make this nation prone to landslides. The primary goal of this research is to compare the application of the fuzzy logic technique and the adaptive neuro-fuzzy inference system (ANFIS) approach to landslide detection sensors based on prior research in order to identify landslide-prone locations more easily. The Adaptive Neuro-Fuzzy Inference System (ANFIS) technique analyzes the landslide area using three factors. Rainfall, land slope, and soil moisture are examples of these factors. This variable is used to assess the area's level of vulnerability to landslides: very safe, relatively safe, relatively potential, potential, and very potential. In the study, each piece of data is subjected to a training and testing procedure to identify landslide vulnerability, with the factors and weighting methods aligned with current government standards. This study compares the rules outcomes to those of past studies as well as the system results. Based on the studies findings, it can be stated that the decision support system for the degree of landslide vulnerability utilizing the ANFIS approach is superior to the fuzzy logic method, with an accuracy rate of 86.21%.

Abstract

Pakuan University (UNPAK) currently has 6 faculties for undergraduate programs, vocational schools, graduate, and post-graduate programs, with an interconnected fiber optic network. The management of the fiber optic network is carried out by Putik as O & M in collaboration with Moratel as the internet connection provider with a bandwidth of 550 Mbps. Analyzing the bandwidth capacity of the fiber optic network is crucial for the implementation of e-learning at Pakuan University. E-learning plays an important role in supporting the teaching and learning process during the Covid-19 pandemic, whether online or remote learning. Based on the daily user recapitulation, it is known that e-learning usage peaks between 08.50 – 10.30 Western Indonesian Time on an usual Monday with 6,505 users in total. The Faculty of Social and Cultural Sciences (FISIB) holds the highest usage of 143.23 Mbps, along with other faculties which exceeds the predetermined capacity of 40 Mbps each. This caused the Simple Queue method to experience access delays of even Request Time Out (RTO) conditions. Therefore, the Simple Queue method is no longer adequate, making the Queue Tree method the better option.

Abstract

Measurement of flow rate in wastewater pipes is still challenging to be done in real-time. The main challenge in wastewater measurement is the non-homogeneity of wastewater due to the presence of solid waste material. This becomes a hindrance when using mechanical flow measurement or direct contact between the fluid and the measuring device. Therefore, the solution is to perform non-contact flow measurement between the fluid and the measuring device. In this study, a flow sensor was developed for a horizontal pipe using the cross-sectional area measurement method on a horizontal pipe measured by an ultrasonic sensor as the fluid level measuring device. The ultrasonic sensor can measure the height of the fluid level, allowing the flow velocity and cross-sectional area of the horizontal pipe to be determined. The basis of this measurement is that any flowing fluid in a pipe that experiences a change in velocity will also experience a change in volume or fluid level. This measurement is in accordance with the continuity equation. From the calibration results, an error of 1.7% was obtained for the height measurement from the ultrasonic sensor compared to the ruler used as a height calibration tool. Meanwhile, the error in the flow velocity measurement from the ultrasonic sensor compared to the calibration results using the tracker software was 4.2%. The error in volume measurement from the ultrasonic sensor compared to the standard measuring tool, a 5-liter beaker glass, was 0.8%. As a conclusion, flow rate measurement using the ultrasonic sensor with the cross-sectional area measurement method can be used to measure the flow rate in a horizontal pipe with a diameter of 11 cm.

Abstract

Lightning is a dangerous natural phenomenon due to its high-voltage electrical energy, which can cause significant damage. The primary hazard of lightning is direct strikes, potentially leading to severe burns, organ failure, and even death. Additionally, lightning can trigger fires, disrupt power grids, and cause explosions. To mitigate these risks, this research focuses on designing a lightning detection system using the "rolling sphere" method. The lightning strike zone is modeled using CorelDRAW software, aiding users in visualizing areas prone to lightning strikes. The device is assembled with electronic components designed to detect lightning based on the method, considering parameters such as peak current, current steepness, charge, and impulse force. Once assembled, the system undergoes testing in an open area at the Faculty of Engineering, Sultan Ageng Tirtayasa University, to verify its functionality and accuracy. Testing is conducted at night to minimize weather-related disturbances, such as Cumulonimbus clouds. The results confirm that the device operates as expected, successfully identifying areas at risk of lightning strikes. This system is anticipated to enhance safety and infrastructure protection in lightning-prone regions.

Abstract

This paper proposes a novel control strategy for enhancing power quality through the implementation of an Interval Type-2 Fuzzy Logic Controller (T2FLC) for Shunt Active Power Filters (SAPF). The presented method effectively addresses harmonic distortions introduced by non-linear loads, a common issue in modern electrical systems. Extensive simulations conducted in MATLAB/Simulink demonstrate the T2FLC's ability to regulate the DC bus voltage while significantly reducing Total Harmonic Distortion (THD). The method achieves superior performance compared to both traditional passive and active filtering techniques, reducing THD within the limits specified by IEEE 519-2014 standards. The results confirm the robustness and adaptability of the proposed approach across varying load conditions, establishing it as a reliable and scalable solution for improving power quality in complex electrical networks.
