    Using of Thesaurus in Query Expansion on Information Retrieval as Value Creation Strategy through Big Data Analytics

    Authors: Graha Noviana, Agus Rahayu, Ratih Hurriyati, Lili A. D. I. Wibowo, Erwin Yulianto, Rizky Jumansyah

    Abstract

    Research still does not frequently use the concept of value creation through the application of big data analytics. Additionally, the internet serves as a limitless supply of knowledge that comes from different people all over the world and is delivered in a variety of ways, including text documents, photos, audio files, and video. Search engine is a tool used to find different types of information on the internet. The issue that frequently occurs when looking for information online is that the search results for the intended subject are frequently unrelated to the terms entered. In order to increase the relevance of the data obtained from the search results, the goal of this study is to implement the query expansion approach, which involves reformulating the initial query in order to add several phrases utilizing a thesaurus. The waterfall model was used in conjunction with the Software Development Life Cycle (SDLC) in the research. The results showed that the creation of a document search engine based on an information retrieval system was able to enhance data relevance and the standard of document search outcomes in big data analysis. The recall results are higher due to the usage of query expansion, which allowed for the retrieval of more pertinent documents. It is clear that by adopting this technique, the relevancy of the data in the search system can be improved. © School of Engineering, Taylor’s University.

    Designing the Plastic Wrapping Trolley in the Packing Process to Reduce the Risk of Injury on Musculoskeletal Disorders (MSDS)

    Authors: M. Yani Syafei, Agus Riyanto, Gabriel Sianturi, Hasna Nafisa

    Abstract

    PT. SMC is a filter trading company that involves business processes such as inventory, packing, and delivery. Manual material handling activities in the packing process are considered non-ergonomic and can lead to musculoskeletal disorders. One of the packing process activities is plastic wrapping on crates, in which workers carry 12 kg of plastic rolls around a 120×120×150 cm crate, starting from a bending position and lifting the plastic roll to a standing position. The goal of this study was to analyze and improve the wrapping process in terms of ergonomics and productivity. To assess the condition of activities, the Nordic Body Map and Rapid Entire Body Assessment (REBA) methods were used. In addition, a plastic wrapping tool is designed to help the worker in packing activities, and the Quality Function Deployment (QFD) method was used to develop the design process. According to the results of the nordic body map data, many workers have a complaint of pain in the waist and right hand. Using the REBA assessment for the existing condition was obtained the risk level of the lower position was very high, the risk level of the middle position and the upper position were high, while the output of the wrapping processes was 19 pallets per day. Three tool designs were developed, and the plastic wrapping trolley was selected as the best design. After using tools, the research shows that the plastic wrapping procedure in. PT. SMC is classified as non-ergonomic, causing a high risk of harm to the waist and right hand. By using the quality function deployment approach, a wrapping trolley is chosen to be manufactured, and the end REBA value is 3, indicating a low risk level. Another benefit shows that, there was an increase in manufacturing output specifically from 19 pallets/day to 37 pallets/day. © School of Engineering, Taylor’s University.

    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.

    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.
