Abstract

Re.wood is a wooden furniture business located in Tinggarjaya Village, Jatilawang District, Banyumas Regency that offers a variety of furniture products, ranging from chairs to wall hangings, to beautify interior and exterior spaces, but still has a limited market share. Re.wood currently uses a conventional sales process that is less effective and lacks information for customers, which causes a lack of sales levels for Re.wood. Designing a system before entering the system development stage is a must because it ensures that the resulting solution is relevant and effective in overcoming the problems users face. The problem can be solved by designing User Interface and User Experience of web-based e-commerce applications. The design method used by researchers is the user-centered design method. User-centered design is a method of focusing on the needs of potential users in the system design stage or process. The results of designing the user interface and user experience only include the user interface developed using Figma. The resulting website produces menus such as Home Page, login, Shop, Cart, Search, and Profile. This evaluation utilized the User Experience Questionnaire (UEQ) methodology to assess various aspects of the system. The resulting values (1.55 for Efficiency, 1.54 for Attractiveness, 1.49 for Clarity, 1.33 for Accuracy, 1.5 for Stimulation, and 1.15 for Novelty) represent the average UEQ calculation figures for each dimension. In other words, these numbers correspond to the results obtained through the UEQ, which helps evaluate user experience in terms of efficiency, attractiveness, clarity, accuracy, stimulation, and novelty. UEQ uses a Likert scale to measure user experience, and the resulting values show that the system performs well in most aspects. These findings indicate that the prototype meets the needs and provides a satisfying user experience.

Abstract

The advancement of the digital era provides many conveniences in various fields. This is because its presence can support the sharing of human activities. One of the conveniences that can be felt is the digital transformation in the implementation of English certification to improve the effectiveness and quality of its implementation. English certification through a web-based English Competency Test (ECT) is a form of digital transformation used to certify English at the Telkom Institute of Technology Purwokerto. However, in practice, the use of the English Competency Test (ECT) system still has several shortcomings, such as the appearance on the English Competency Test (ECT) is less attractive and difficult to understand, the access process is less responsive and some features are not functioning properly. Therefore, to correct the existing deficiencies, it is necessary to evaluate the effectiveness of use. This study is here to analyze the quality assessment of the English Competency Test (ECT) system. By using the Computer System Usability Questioner (CSUQ) instrument in the form of a questionnaire to assess the effectiveness, efficiency and convenience provided by ECT. The results showed that the usability of the English Competency Test (ECT) system was “Neutral” with a feasibility percentage of 58%. Neutral indicates that the English Competency Test (ECT) can be used, but still cannot be said to be good. Based on the research results, improvements can be made to the Information Quality section by providing error messages and improvements and improvements to the Interface Quality section to make it more user friendly.

Abstract

Programming learning success is an important indicator in information technology education; many students still struggle to understand algorithmic concepts, logic, and code implementation. This problem indicates that a data-driven approach is needed to identify students' initial successes and failures in programming learning. The purpose of this study is to develop and validate a predictive model for programming learning success using Support Vector Machine (SVM), a classification algorithm. This research method includes steps such as data collection and preprocessing, feature selection, splitting the dataset into training and test sets, training the SVM model with parameter optimization, and evaluating performance using the test set. The results show that the SVM model achieves good classification performance with an accuracy of 87.5%, precision of 85.7%, F1 score of 87.8%, and AUC of 0.91, placing it in the excellent category. These findings indicate that the model has strong discriminatory power in distinguishing between successful and unsuccessful students. Therefore, the SVM method has been proven effective as a data-driven prediction system. This also allows for the development of more targeted and adaptive learning intervention strategies and academic decision-making.

Abstract

Identification of potential fishing zones remains a significant challenge in fisheries management, particularly in coastal and island waters characterized by high spatial and temporal environmental variability. In Batam waters, fishing activities are still dominated by fishermen's experience and heuristic judgment, while existing studies often focus on a single prediction model or limited environmental parameters. This indicates a research gap, namely the lack of an integrated framework that simultaneously captures environmental heterogeneity and improves prediction accuracy using a data-driven approach. To address this gap, this study proposes a hybrid data mining framework that explicitly integrates unsupervised environmental zoning and supervised classification for predicting fishing potential. Weather and oceanographic variables—including sea surface temperature, chlorophyll-a concentration, wind speed, ocean current speed, and salinity—are used in conjunction with historical fish catch data. K-Means clustering is first used to identify homogeneous marine environmental zones, which are then incorporated as contextual features into a Random Forest classification model. Model performance is then evaluated using accuracy, precision, recall, F1 score, and confusion matrix analysis. The results show that the proposed hybrid approach achieves an accuracy of 89.2% and an F1 score of 89.1%, representing a quantitative improvement of approximately 5.6% in accuracy and 5.0% in F1 score compared to the baseline Random Forest model without clustering. This comparison clearly demonstrates that the integration of clustering information significantly improves classification performance. Furthermore, feature importance analysis confirms that sea surface temperature and chlorophyll-a concentration are the most influential predictors, while cluster labels contribute indirectly by improving the model's contextual understanding of complex environmental conditions. The novelty of this research is articulated through the integration of unsupervised marine environmental zoning with supervised machine learning in a local fisheries context, which allows for improved predictive performance and enhanced model interpretability. Unlike conventional approaches that treat environmental variables independently, the proposed framework captures multidimensional environmental interactions in a structured manner. The implications of these findings are profound. The proposed model can support data-driven decision-making for fishermen by reducing search time and operational costs, while providing a scientific basis for fisheries managers for spatial planning and sustainable resource management. Therefore, this research contributes both methodologically and practically to the advancement of intelligent fisheries prediction systems in dynamic coastal environments such as Batam waters.

Abstract

The escalation of cyber threats and the growing complexity of digital asset management within government agencies necessitate the strengthening of structured information security governance. This paper documents a community service initiative conducted at DINKOMINFO Purbalingga, aimed at enhancing human resource capabilities in implementing an Information Security Management System (ISMS). The primary focus of the program was the dissemination and simulation of the KAMI 5.0 Index instrument, which serves as the latest adaptation of the ISO/IEC 27001:2022 standard. The implementation method consisted of face-to-face training involving 23 participants from various cross-sectoral agencies, employing a theoretical-analytical approach. Evaluation results indicated an improvement in participants' comprehension regarding information asset classification and self-evaluation mechanisms. The majority of participants expressed a very high level of satisfaction (Strongly Agree) regarding the relevance of the material, although response variations reflected the dynamic nature of participants' understanding. The success of this initiative demonstrates DINKOMINFO's strategic readiness to transition towards a more rigorous and accountable national information security framework
