    Authors: Mulyawati I. B, Riza M, Dermawan H, Pratiwi V

    DOI: 10.5829/ije.2023.36.04a.18

    Abstract

    In Indonesia, the construction of the road has challenges because the road was built on soft clay soil. The vacuum preloading method was used to improve the shear strength and compressibility properties of soft soil in this project. Moreover, what needs to be a concern for practitioners is the issue of increasing simulation accuracy in predicting soil settlement in a vacuum preloading system. The research objective of this study was to determine changes in soil settlement behavior that occurred from the vacuum preloading system using a numerical simulations Geostudio with the 2D Multi Drain-Plane Strain approach and the settlement result of the simulation will be compare with instrumentation data. In this study the vacuum pressure distribution is modeled using water total head negative pore water pressure and the pressure value used following vacuum gauge data in the field with distribution approach is 100% at the surface of the sand platform, 85% to a depth of 5 m, then 60% to the end of the PVD. Based on the simulations, the conlusion is the vacuum pressure applied along the vertical drainage is not modeled constant, but changes with depth, the value of 60% at the bottom of the vertical drainage is quite representative of the conditions in the field and the settlement from the simulation is quite good at approaching the field observation with a prediction of the settlement due to vacuum preloading of 0.93 m, when compared to the field observation data there is a difference of about 1.6%. © 2023 Materials and Energy Research Center.

  • Smart Urban Farming Application: UV Light in Hydroponic Installations

    Smart Urban Farming Application: UV Light in Hydroponic Installations

    Authors: Herry Saputra, Irfan Dwiguna Sumitra, Dedeng Hirawan, Rudhi Lesmana, Eddy Soeryanto Soegoto

    Abstract

    Hydroponic farming is an innovative method of cultivating plants without soil media. It has become a popular solution to address limited agricultural land, especially in urban areas. Indoor hydroponics is a type of hydroponic farming that involves growing plants in a room that lacks natural sunlight. Instead, Ultraviolet (UV) lights are used to ensure that the plants receive sufficient light. The goal of this research is to investigate how UV radiation affects plants in hydroponic growth systems when they are grown in a room with little sunlight. The study used quantitative methods with data collection techniques based on observation. The hydroponic plants were exposed to UV radiation during their growing period, and their growth was closely monitored. The findings of this study indicate that when plants are grown in a closed room exposed to UV light, they exhibit optimal growth due to proper light intake and nutrient maintenance. A consistent irrigation system and UV lighting have a positive impact on the shape and quality of the plants’ roots and leaves, making them healthier and stronger. This is because plants’ UV light requirements can still be met even when they are kept indoors. © School of Engineering, Taylor’s University.

  • Implementation of Convolutional Neural Network for Sundanese Script Handwriting Recognition with Data Augmentation

    Implementation of Convolutional Neural Network for Sundanese Script Handwriting Recognition with Data Augmentation

    Authors: Irfan Maliki, Ade Syahlan Prayoga

    Abstract

    Sundanese script is one of the cultural heritages that need to be preserved. However, Sundanese script has complexity and uniqueness in its writing, making it difficult to recognize. The recognition can be done automatically using deep learning. One of the problems is that the recognition has a small amount of data and is less varied. In this study, the proposed solution is to use data augmentation. This study focused on how the use of data augmentation can help to improve accuracy in performing the recognition of handwriting image pattern using Convolutional Neural Network (CNN) method. Data augmentation is the process of artificially increasing the amount of data by generating new data points from existing data. The augmentation includes adding small changes to the data or using machine learning models to generate new data points in the latent space of the original data in order to strengthen the data set. Data augmentation applied in this research is flipping, rotation, and translation techniques. Based on the results, it can be concluded that the use of data augmentation to increase the number and variety of data samples has a significant effect on the accuracy value of 0.1707 or about 17.07%. The best accuracy obtained is 0.8 or 80% using a baseline model with data augmentation. These findings yielded good results because the system is able to perform image classification quite well. © School of Engineering, Taylor’s University.

  • Efficient Sampling-Based for Mobile Robot Path Planning in a Dynamic Environment Based on the Rapidly-Exploring Random Tree and a Rule-Template Sets

    Efficient Sampling-Based for Mobile Robot Path Planning in a Dynamic Environment Based on the Rapidly-Exploring Random Tree and a Rule-Template Sets

    Authors: Muhammad Aria Rajasa Pohan, Jana Utama

    DOI: 10.5829/ije.2023.36.04a.16

    Abstract

    This study presents an efficient path planning method for mobile robots in a dynamic environment. The method is based on the rapidly-exploring random tree (RRT) algorithm. The two primary processes in mobile robot path planning in a dynamic environment are initial path planning and path re-planning. In order to generate a feasible initial path with fast convergence speed, we used a hybridization of rapidly-exploring random tree star and ant colony systems (RRT-ACS). When an obstacle obstructs the initial path, the path re-planner must be executed. In addition to the RRT-ACS algorithm, we proposed using a rule-Template set based on the mobile robot in dynamic environment scenes during the path re-planner process. This novel algorithm is called RRT-ACS with Rule-Template Sets (RRT-ACS+RT). We conducted many benchmark simulations to validate the proposed method in a real dynamic environment. The performance of the proposed method is compared to the state-of-The-Art path planning algorithms: RRT∗FND and MOD-RRT∗. Numerous experimental results demonstrate that the proposed method outperforms other comparison algorithms. The results show that the proposed method is suitable for the use on robots that need to navigate in a dynamic environment, such as self-driving cars. © 2023 Materials and Energy Research Center.

    Computational Bibliometric Analysis Of Evolutionary Game Theory (EGT) Research Using Vosviewer

    Authors: Rizky Jumansyah, Eddy Soeryanto Soegoto, Chepi Nur Albar

    Abstract

    Evolutionary Game Theory (EGT) applies mathematical theory to the biological context, providing an analytic framework, contest, and strategy. The assumption underlying EGT is that human behavior, whether in games or decision-making problems, often does not arise from rational reasoning. This study aimed to perform a bibliometric analysis of EGT using VOSviewer software to map the research landscape. The approach used was bibliometric and descriptive quantitative, with data obtained from a Google Scholar search for articles with the keyword “Evolutionary game theory” using the publish or perish application. The search yielded 990 articles published between 2017-2021. The results showed that research on EGT peaked in 2017-2019 but declined in 2020 and 2021. In conclusion, this study highlights the importance of bibliometric analysis, particularly in the field of EGT, and provides a reference for future research on this topic. © School of Engineering, Taylor’s University.

  • Pupil Center Detection Using Radial Symmetry Transform to Measure Pupil Distance in the Eye

    Pupil Center Detection Using Radial Symmetry Transform to Measure Pupil Distance in the Eye

    Authors: Utama J, Fitriani V. R. L

    DOI: 10.5829/ije.2023.36.05b.04

    Abstract

    In patients with refractive errors or impaired vision, light rays received by the pupil do not fall directly onto the retina. This can be corrected by wearing monocled glasses. The focal point of the eyeglass lens needs to be adjusted to the center of the user’s pupil. This can be known through the measured pupil distance (PD) value information. The measurement of the PD is very important to determine the center distance of the pupils in both eyes. where the eye does not experience the prism effect. This study aims to apply the radial symmetry transformation (RST) method combined with self-quotient (SQI) imagery to detect the pupillary center and measure PD. This algorithm combines to get more optimal results in detecting the center of the pupil in dark conditions or those exposed to shadow illumination. The program created using the MATLAB software simulates PD measurements for pupillary center detection in bright and dark images conditions. The test was carried out ten times, and the results showed that the system was able to measure PD on low-resolution images of 300 x 300 pixels at 72 dpi in bright image conditions; with measurement uncertainty values in each image of 0.60 mm. As for testing on dark images, the uncertainty values are 0.80 mm. In this case, the standard deviation value is obtained from the effect of the different dimensions of the face object on the tested image. © 2023 Materials and Energy Research Center.
