  • Odour Pollution Control Using Type-2 Fuzzy Logic Controller

    Odour Pollution Control Using Type-2 Fuzzy Logic Controller

    Authors: Muhammad Aria Rajasa Pohan, Dhiyaa Rifqi Taufiqurrahman, Fernando Sitanggang, Vania Retha Luthfia Fitriani

    Abstract

    This investigation aims to develop an odour reduction system simulation using a Type-2 Fuzzy Logic Controller (T2FLS). T2FLC is a further development of the classic fuzzy logic (Type-1 Fuzzy Logic Controller or T1FLC). Where the membership function of T2FLC is also fuzzy. A test by several references indicates that the performance of T2FLC is better than the T1FLC. The proposed T2FLC is tested and compared to the PID controller and T1FLC. The test is based on simulation using MATLAB and Simulink®. Three attempts are carried out to compare the performance of the three controllers using three different gain (C), time delay (L), and time constant (T) values. This shows that type-2 fuzzy is the most reliable method for magnifying C, L, and T values with rise time = 1.368 seconds, maximum overshoot = 60%, and settling time = 8.989 seconds. © 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.

  • A Bert Model to Detect Provocative Hoax

    A Bert Model to Detect Provocative Hoax

    Authors: Rio Yunanto, Eri Prasetyo Wibowo, Rianto R

    Abstract

    The information flood makes social media users vulnerable to becoming victims of provocative hoaxes or even spreading hoaxes themselves. This research examines the capabilities of two variants of Bidirectional Encoder Representations from Transformers (BERT) models for the Indonesian language (IndoBERT Base Model and Indonesian BERT base model 522M) in developing the detection of provocative hoaxes in the Indonesian language. The proposed method used two variants of the monolingual BERT model for the Indonesian language from the Huggingface library. The proposed method’s architectural flow starts with data collection and labelling from community hoax collector websites, followed by pre-processing. The cleaned data is then divided into training and test data to proceed to the fine-tuning stage, where several layers and weights of the BERT model are adjusted to fit the desired classification task. The experimental results of the study show that the recommended Indonesian BERT variant for the detection of provocative hoaxes is the IndoBERT Base Model with a learning rate of 1e-5, a batch size of 32, and a maximum length limit of 128 tokens, achieving an average training accuracy of 99,22%, with a training time of 21min 52s. The research findings also indicate that a learning rate 1e-5 can produce better test accuracy than a learning rate of 2e-5 or 3e-5. The detection model of provocative hoaxes using Indonesian BERT variants needs to be improved, especially in terms of collecting a large amount of hoax data, to enhance the accuracy of the provocative hoax detection model. © School of Engineering, Taylor’s University.

  • The Production of Mingling Spaces as a Form of Children’s Mobility

    The Production of Mingling Spaces as a Form of Children’s Mobility

    Authors: Dhini Dewiyanti, Andiyan, Dianna Astrid Hertoety, Tri Widianti Natalia

    DOI: 10.13189/cea.2023.110613

    Abstract

    The city of Bandung in Indonesia is facing challenges due to the decreasing availability and high prices of land. This has resulted in settlements that do not meet the basic housing requirements, including providing open spaces or communal areas for residents. As part of the community, children are particularly affected by spatial injustice caused by the lack of space, specifically for playing. Furthermore, children in Bandung often visit play areas in other communities. Preliminary research are indicating some interesting phenomena, including 1) the existence of spaces in settlements that are only used by children from the specific community and 2) the existence of spaces that are shared and used by children from various surrounding settlement areas. These shared spaces, where children from different areas come together to play, are called “mingling spaces”. Therefore, this research aims to identify and understand the mingling spaces that emerge from children’s activities during their collective play. It was conducted in three settlement areas in North Bandung with shared play spaces. Data were collected by observing the play behaviour of children aged 4-12. Spatial analysis using social constructivism methods provides an understanding of the mingling spaces between two different communities. Mingling spaces in this research are manifested as a “third space” referred to as the ‘Dynamic Third Space’. Mingling space is dynamic because it is temporal, tends to disappear at any time, and can be permanent and also mobile. Mingling spaces exist due to shared goals, time, and access. These findings indicate a tendency towards spatial injustice, specifically for children, in obtaining their rights to suitable play spaces. © 2023 by authors. All rights reserved.

  • The Ensemble Method and Scheduled Learning Rate to Improve Accuracy in CNN Using SGD Optimizer

    The Ensemble Method and Scheduled Learning Rate to Improve Accuracy in CNN Using SGD Optimizer

    Authors: Suhirman S, Rianto R, Insap Santosa, Rio Yurianto

    Abstract

    Indonesia is an agricultural country where most people work as farmers. As an agricultural country, Indonesia produces staple foods, such as rice, corn, sago, and fruits. This research uses the Convolutional Neural Network (CNN), one of the popular algorithms in Deep Learning to classify two varieties of fruit using Stochastic Gradient Descent (SGD) optimizer. The data used in this research is the primary data collected using a smartphone camera. The data are 400 images of two fruit varieties, Mango, and Avocado. The main research objective is to obtain the highest accuracy by modifying the classifier model and learning rate. The model modification, this research uses an ensemble system while in learning rate using an exponential scheduled learning rate. The result shows that the accuracy of the ensemble system is 0.99, the scheduled learning rate is 0.97, while without modifications is 0.53, respectively. However, when using the SGD optimizer to train CNN, it is advised to use a predefined learning rate. A shorter training period with sufficient model accuracy and practicality supports the scheduled learning rate. © 2023 Taylor’s University. All rights reserved.

    BANDUNG, UNIKOM – Thursday, July 1, 2026, the Visual Communication Design (VCD) and Graphic Design study programs at the Universitas Komputer Indonesia (UNIKOM) held a Seminar on Theses and Final Projects for the Even Semester of the 2025/2026 Academic Year, held in the 4th-floor auditorium of the UNIKOM Miracle Building. Under the theme “Creative Chat! Exploring Industrial Design and the Power of Public Speaking,” the event served as a platform to equip students in preparing their final projects while also helping them face the challenges of an increasingly dynamic professional world.

    The Chair of the Final Project Seminar Organizing Committee, Dhika Mega Pratama, M.Ds., expressed gratitude in his report for the enthusiasm shown by the participants. He noted that the seminar was attended by 134 students currently enrolled in Final Project (TA) and thesis courses, as well as faculty members and members of the general public. He hoped that all students would participate in the entire series of activities until completion to gain the maximum benefit.

    Meanwhile, the Final Project and Thesis Coordinator for UNIKOM Visual Communication Design (VCD) Program, Deni Albar, S.Sn., M.Ds., noted in his remarks that the presence of the two guest speakers Arman Sidik and Gita Andriani was by no means coincidental. “We selected them because they possess experience and expertise highly relevant to the needs of students currently working on their final projects. Kang Arman is a design practitioner with extensive professional experience. He has been in the same position as our students are now, so the insights he shares are expected to provide both inspiration and a realistic picture of the creative industry. Meanwhile, Gita Andriani is both a practitioner and a trainer in the field of public speaking. The ability to convey ideas and present work effectively is one of the key competencies students must possess, especially when facing seminars or final project defense sessions,” he explained.

    The series of activities continued with an opening address by the Head of the Visual Communication Design Study Program at UNIKOM, Dr. Kankan Kasmana, S.Sn., M.Ds., in his capacity as representative of the Dean of the Faculty of Design, Prof. Dr. Lia Warlina, M.Si, Ir. In his remarks, he noted that the Thesis and Final Project Seminar is a regular annual event held as part of the preparation for students nearing the completion of their studies. According to him, the seminar is intended to help students overcome “mental blocks,” particularly the perception that graduates of private universities have limited opportunities. On the contrary, through the insights and experiences shared by the speakers, students are expected to develop a more positive, confident, and optimistic mindset, recognizing that opportunities to create and build a career in the creative industry are vast and wide open.

    During the main session of the seminar, students gained insights into developments in industrial design, the creative process involved in producing work relevant to industry needs, and the importance of public speaking skills as a competency that design graduates must possess. The material was presented by speakers Arman Sidik and Gita Andriani, moderated by Satria Indra Praja Persada, S.Ds., M.M., a Visual Communication Design lecturer at UNIKOM who also has professional experience in the field of graphic design. Throughout the seminar, participants were also encouraged to actively engage in discussion during the Q&A session.

    Through the Thesis & Final Project Seminar, UNIKOM Visual Communication Design and Graphic Design programs demonstrated their commitment to supporting the improvement of students’ academic quality. Not only did the event equip participants with technical knowledge for preparing their final projects, but it also strengthened their communication skills, creativity, and readiness to enter the ever-evolving world of work and the creative industry.

  • Autonomous Cyber-Physical System Control Using Fuzzy Type 2

    Autonomous Cyber-Physical System Control Using Fuzzy Type 2

    Authors: Sopian Alviana, Taufik Djatna, Shelvie Nidya Neyman, Sri Wahjuni

    Abstract

    Environmental changes in a dynamically changing system require monitoring and control to maximize the results obtained. This research aims to utilize an autonomous control process for cyber-physical systems using type 2 fuzzy logic, which has been fine-tuned to achieve optimal results. The initial framework employed involves developing an interaction framework between physical and cyber components within a cyber-physical system framework. The control process implemented utilizes type 2 fuzzy logic, incorporating uncertain values. Type 2 fuzzy logic is chosen to handle changes in parameter values effectively within the dynamic cyber-physical system environment. The results indicate that the control process employing type 2 fuzzy logic during the cyber-physical system tuning process yields a smaller error value than using type 1 fuzzy control. The accuracy achieved with type 2 fuzzy logic is 98.84% in the control process. Autonomous control plays a crucial role in the decision-making process, facilitating the attainment of optimal result values in controlling dynamic environments. © 2024 Taylor’s University.

  • Application of Data Mining for Predicting Horticultural Commodities Price

    Application of Data Mining for Predicting Horticultural Commodities Price

    Authors: Dian Dharmayanti, Arsy Opraza Akma, Eddy Soeryanto Soegoto, Lia Warlina

    Abstract

    In Garut Regency, farmers receive their commodities at a selling price that collectors determined. This issue causes farmers to lose money because their income does not correspond with the market price for their goods. This loss has an impact on reducing farmer productivity. Therefore, this research aims to provide recommendations to farmers regarding commodity selling prices for particular periods based on forecast results. This research implements data mining so commodities selling prices can be predicted. Data mining is a way to find patterns or knowledge from past data. Multiple linear regression methods or algorithms are used to find patterns or knowledge with data mining. Multiple linear regression can be used to predict commodities selling prices based on rainfall factors and total production. The application developed can produce recommendations for farmers for commodity selling prices for specific periods based on prediction results, thereby reducing losses for farmers. © 2024 Taylor’s University.
