    Authors: Ma’Shum Abdul Jabbar ; Martin Roestamy ; Himmatul Miftah ; Irman Suherman ; Muhammad Encep ; Bobi Kurniawan Soegoto

    DOI: 10.1109/INCITEST64888.2024.11121469

    Abstract

    This study aims to overcome the challenges in selecting the most efficient machine learning model to analyze user sentiment towards the BRImo application on the Google Play Store. User review data on BRImo, an application owned by PT Bank Rakyat Indonesia, was collected through web scraping techniques from a total of 1.55 million reviews, and then 150,000 relevant samples were used. The results showed that Support Vector Machine (SVM) had the highest accuracy rate (87.13%) but required the longest training time (1310.70 seconds). In contrast, Naive Bayes had the shortest training time (0.59 seconds) but the lowest accuracy (75.00%). Logistic Regression emerged as a model that provides a balance between high accuracy and fast execution time. The contribution of this study is to provide a comprehensive guide to the efficiency and reliability of models in sentiment analysis, which can be used to assist in selecting the right model in new user review analysis. © 2024 IEEE.

  • Deflection Enhancement of Ferrite Magnetic Core-Based Microactuator

    Authors: Roer Eka Pawinanto, Budi Mulyanti, Jahril Nur Fauzan, Ayub Subandi, Lilik Hasanah, M. Assadillah Pangestu, Jumril Yunas

    DOI: 10.11591/eei.v14i2.8448

    Abstract

    Microactuators play a vital role in several microelectromechanical systems (MEMS) that generate forces or deflections necessary to accomplish functions such as scanning, tuning, manipulation, or delivery. Utilizing a ferrite magnetic core has shown the potential to enhance the deflection of the microactuator. However, the previous study presented a complex fabrication method with high power consumption unsuitable for micropump application. Herewith, we report the impact of ferrite core length on the deflection generated by a microactuator with a simple fabrication method. The deflection behavior shows that the corresponding magnetic core length is inverse to the deflection improvement. The force reduction generated led by a longer magnetic core because of the farther distance to the coil. Our study can be used as a reference to support the development of micropump or active micromixer devices, which require compact devices with simple fabrication and high deflection, achieving ultra-high flow rate and high mixing index. © 2025, Institute of Advanced Engineering and Science.

    DOI: 10.15549/jeecar.v10i6.1505

    Abstract

    This study aimed to investigate and comprehend the effects of knowledge management adoption, information technology utilization, and community service programs on university branding and their subsequent impact on the overall quality of education in private tertiary institutions (PTS) in the West Java and Banten region. The research design was quantitative, using a survey approach and a simple random sampling method to gather data from 226 lecturers from private tertiary institutions in West Java and Banten. PLS software version 3.0, based on the Partial Least Squares (PLS) approach, was used to analyze the data. The results showed that knowledge management implementation had no discernible impact on university branding, as shown by a t-statistic value of 1.594 and a P-value of 0.112. © 2023, Institute of Eastern Europe and Central Asia.

  • Comparative Analysis of Software Quality Model 

    in the Selection of Marketplace E-Commerce

    Authors: Rahma Wahdiniwaty ; Eko Budi Setiawan ;  Deden A Wahab

    DOI: 10.1109/ICITSI.2018.8696074

    Abstract

    E-commerce system is very helpful for people in buying and selling transactions. Various existing marketplaces have their advantages and disadvantages. Software quality models can provide an assessment of each e-commerce marketplace system. This research analyzes the results of e-commerce selection by using several software quality models that are implemented with the analytical hierarchy process using Expert Choice tools. The assessment in this research using criteria from a combination of several quality software models to obtain which criteria have the highest percentage value and determine the quality of an e-commerce marketplace system. Each quality model software has different evaluation results from each other. This difference because the assessment criteria between one quality model and another. © 2018 IEEE.

    Authors: Resa Nurlaela Anwar ; Vanessa Gaffar ; Disman ; Chairul Furqon ; Yayah Sutisnawati

    DOI: 10.15549/jeecar.v10i6.1499

    Abstract

    Fintech innovations such as mobile wallets (m-wallet) are reshaping the payment landscape, m-wallet users in Indonesia are relatively high, but there is a gap in the number of m-wallet users by age group. The highest number of m-wallet users, mostly the young generation, is based on age. The digital immigrant generation is another age group with the potential to increase but still needs to be higher in adoption. This research’s primary objective is to determine the effect of m-wallet adoption in Indonesia. This study aimed to comprehend how consumers adopted m-wallets. Four hundred respondents categorized as digital immigrants in Indonesia were surveyed quantitatively using a cross-sectional study approach using Smart PLS 3.1, and Partial Least Square Structural Equation Modeling (PLS-SEM) was used to evaluate the obtained data. The findings showed that perceived behavioral intention is significantly influenced by Perceived Usefulness (PU), Perceived Ease of Use (PEOU), Perceived Security (PS), and Perceived Trust (PT). Consumer Behavioral intention is also significantly influenced by m-wallet adoption by digital immigrants in Indonesia. © 2023, Institute of Eastern Europe and Central Asia. All rights reserved.

  • Systems and Services Pattern Descriptions at Daycare

    Authors: Syafariani R. Fenny ; Andri Sahata Sitanggang ; Eko Yudhi Pramono; Wahidah Hashim ; Andino Maseleno

    DOI: –

    Abstract

    A daycare is a service provided when a woman wants to leave their children. However, their doubts and trusts about a daycare are one of the important factors in choosing it. Thus, the daycare services should be able to address the concerns that exist today. One of the services provided is the ease in using these services, with the existence of information technology in the form of a child care information system as one of the solutions. Child Care Information System is a system that can manage child registration functions, child service management, as well as payment for services used. If these 3 functions can be managed properly, then it certainly helps daycare in fostering a great sense of trust from mothers / women in entrusting their children. The application of a child care information system can help with problems faced by housewives or working women and the daycare managers. © BEIESP.
