                <text>As climatic products, tomatoes are highly sensitive to harvesting and processing. The sorting of tomatoes can be significantly improved by utilizing Hue Saturation Value (HSV) color features that are classified using neighboring algorithms, such as K-Nearest Neighbor (KNN), Weighted K-Nearest Neighbor (W-KNN), and DW-KNN. However, the DW-KNN algorithm does not consider  the  relative  relationship  between  the  farthest,  nearest,  and  surrounding  neighbors,  which  may  impact  the classification accuracy, particularly in datasets with uneven distributions. This study proposes a Triple Weighted K-Nearest Neighbor (TW-KNN) algorithm for tomato image classification. This algorithm effectively handles the problem of sensitivity and  outliers  in  the  data  distribution  and  considers  the  relationship  between  neighboring  distances.  The  classification  data consisted of 400 tomato images with five maturity levels divided into training and testing sets using k-fold cross-validation. Tests were conducted using several variations of parameter k, namely 4, 6, 9, and 15, to evaluate the classification performance. The results  show  that  the  proposed  TW-KNN  algorithm  consistently  outperforms  other  methods  by  producing  better classification  results.  This  is  demonstrated  by  an  accuracy  rate  of  95.52%  across  different  values  of  k.  The  superior performance of the TW-KNN highlights its ability to provide robust and stable classification results compared to conventional KNN variants. This finding indicates that the TW-KNN is more effective in consistently classifying tomato fruits, making it a promising approach for automated fruit sorting applications</text>

                <text>This study aimed to compare the performance of various Convolutional Neural Network (CNN) architectures, including LeNet, ResNet,  AlexNet,  GoogleNet,  VGGNet,  and  the  proposed  model,  in  medical  image  classification  for  disease  detection.  The proposed model was developed by adding additional layers and fine-tuning the hyperparameters in the ResNet architecture to enhance its ability to extract complex features. The training and testing processes were conducted using an augmented X-ray image dataset to increase the data diversity. The results indicate that the proposed model achieved the highest testing accuracy of 76.33%, surpassing other models in terms of accuracy, precision, recall, and F1-score. Although there are some limitations in specificity and the Matthews Correlation Coefficient (MCC), the proposed model still demonstrates better generalization ability, with an AUC-ROC score approaching an optimal value. These findings suggest that the proposed model has advantages in medical image classification and holds potential for further development to enhance disease classification accuracy</text>

Fake  news  is  often  crafted  to  deceive  readers  and  manipulate  public opinion,  especially  in  political  contexts  such  as  the  2024  Regional  Head  Elections  (Pilkada  2024).  Although  various measures have been proposed to mitigate this issue, achieving an effective balance between controlling misinformation and preserving  free  speech  remains  a  challenge.  This  study  aims  to  address  this  problem  by  developing  a  fake  news  detection model based on Natural Language Processing (NLP) and Long Short-Term Memory (LSTM). The dataset used in this study was  collected  from  public  tweets  related  to  Pilkada,  with  Kompas.com  serving  as  the  validation  source  to  verify  content authenticity.  Experimental  results  show  that  the  proposed  LSTM  model  outperformed  traditional  classification  methods, achieving  a  precision,  recall,  and  F1-score  of  0.95,  along  with  an  overall  accuracy  of  94.90%.  Confusion  matrix  analysis further  confirmed  the  reliability  of  the  model  by  demonstrating  low  misclassification  rates.  This  study  contributes  to  the advancement of AI-driven hoax detection systems, offering an automated and scalable solution for combating misinformation in political discourse</text>

                <text>This study targets improved sentiment classification by combining the strengths of multiple SVM kernels within an ensemble framework. We introduce SVM Porlis, which fuses Linear, RBF, Polynomial, and Sigmoid kernels using both hard and soft voting to boost performance on skewed data. The task is binary sentiment recognition (positive vs. negative). A corpus of 2,248 tweets concerning the debate over the naturalization of Indonesia’s national football players was gathered via the official X/Twitter  API,  with  a  marked  dominance  of  negative  tweets.  The  preprocessing  pipeline  encompassed  cleaning,  labeling, tokenization, stopword removal, stemming, and TF-IDF feature extraction. To counter the imbalance, SMOTE was applied to synthesize additional minority-class samples. Each kernel was first trained and assessed independently, then aggregated into the  SVM  Porlis  ensemble.  Evaluation  used  accuracy,  precision,  recall,  F1-score,  and  confusion-matrix  analysis.  The  soft-voting SVM Porlis model achieved the best results—98% for accuracy, precision, recall, and F1—outperforming single-kernel baselines and otherensembles such as SVM + Chi-Square and SVM + PSO. These outcomes indicate that integrating diverse kernels effectively captures both linear and nonlinear patterns, yielding a robust and adaptive approach for sentiment analysis on real-world, imbalanced datasets</text>

                <text>Recommender systems play a crucial role in personalized decision-making, particularly in the tourism industry, where users seek destinations that align with their preferences. However, traditional recommendation methods often struggle to provide accurate  recommendations. This  researchintroduces  a  hybrid  recommendation  framework  that  combines  Content-Based Filtering (CBF) with Apriori-based association rule mining to improve the accuracy and relevance of recommendations. First, CBF was implemented using TF-IDF, Word2Vec, and BERT embeddings to compute the similarity between user preferences and tourism destinations. The Top-N recommended destinations from each method were then used as antecedents in Apriori to identify  associative  patterns  and  co-occurrence  relationships  among  tourism  destinations.  By  leveraging  both  semantic preference matching and association rule mining, the proposed system refines the recommendation process, ensuring not only personalized  suggestions  but  also uncovering  implicit travel  patterns.  The  experimental  results demonstrate  that  the hybrid model improves recommendation  relevance  and accuracy compared  to  standalone  CBF methods. The  accuracy  of  the  CBF model  was  53.96%,  whereas  that  of  the  hybrid  model  was  94.31%.  The  integration  of  CBF  and  Apriori  offers  a  morecomprehensive and data-driven recommendation framework, which is valuable for personalized tourism applications</text>

                <text>It  will  be  necessary  for  attraction  managers  withinhotels  to  track  guests'  lifestyles  to  keep  the  business  running.  Such  an understanding may be achieved, forexample by analyzing reviews on attractions to capture the attitudes of the visitors towards the services and business within the tourism industry. The approach utilizes web scraping to gather user-generated reviews, using text preprocessing, datapre-processing, and further improvement of the model using labelled sentiment data divided into  three  sentiment  classes:  positive,  negative,  or  neutral.  The  dataset  consisting  of  908  reviews  were  divided  in  70:15:15 ratio for training, validationand testing. The effectiveness of the model was evaluated using accuracy, precision, recall, and the  F1-score.  In  this  study,  theBERT  deep  learning  model  is  used  to  classify  sentiments  of  Indonesian  tourist.  Using  the SmallBERT variant fine-tuned on515k reviews for 5 epochs, the model achieved 91.40% accuracy, 90.51% precision, recall, and F1 score. The results indicate a dominance of positive sentiments, visualized using tableau. This research provides a robust foundation  for  developing  intelligentsentiment-based  recommendation  systems  in  the  tourism  sector  and  suggests  future exploration using other transformer-based models such as GPT, T5, or BART for comparative analysis</text>

                <text>The Thermal Humidity Index (THI) serves as a critical measure of environmental thermal comfort, particularly vital for living beings in densely populated regions. This study projects and classifies THI in the western northern coastal areas of Central Java using Machine Learning (ML) techniques. Utilizing temperature and humidity data from 2018 to 2024, THI projections were conducted using the XGBoost algorithm, whereas comfort level classifications were performed using the Random Forest algorithm.  The  results  indicate  that  Semarang  City,  eastern  Kendal,  Pemalang,  and  Tegal  frequently  experienced  slightly uncomfortable  conditions  (THI  27–30),  particularly  during  the  rainy  and  transitional  seasons,  whereas  other  regions maintained comfortable levels (THI &lt; 27). The THI projection model for 2025–2029 achieved an accuracy of 73%, while the classification model attained a remarkably high accuracy of 99.94%. These findings highlight the need for enhanced regional management strategies in areas with reduced thermal comfort</text>

                <text>This  study  addresses  the  challenge  of  accurately  clustering  earthquake  events  based  on  depth  to  better  understand  seismic activity patterns in Sulawesi from 2019 to 2023. Traditional clustering algorithms often fail to capture the complex spatial and depth-based structures of earthquake data. To overcome this, we employed the DBSCAN algorithm, which is well-suited for identifying irregularlyshaped clusters and handling noise in spatial datasets. A key focus of this research is the systematic optimization of DBSCAN’s parameters—epsilon (ε) and minimum samples (min_samples)—using  a  grid  search  approach. Epsilon values varied from 0.1 to 0.5, and min_samples ranged from 6 to 60. The optimal parameters, determined using the Calinski-Harabasz (CH) index, were ε = 0.4 and min_samples = 54. Compared with previous heuristic settings, the optimized configuration produced better separated and more interpretable clusters. Using the optimized parameters, nine distinct clusters were identified, capturing meaningful patterns in both depth and magnitude. The results revealed that shallow earthquakes (0–20 km) tend to exhibit greater magnitude variation, withsome clusters averaging magnitudes up to 3.7. This suggests a higher seismic hazard potential associated with brittle crustal activity. The findings contribute to seismic hazard analysis by providing a  more  robust  understanding  of  three-dimensional  earthquake  distribution,  aiding  regional  risk  assessment  and  disaster preparedness efforts. These insights can support agencies such as BMKG and BPBD in hazard mapping, sensor deployment, and contingency planning for high-risk zones.</text>

                <text>Heart disease represents a significant global health concern, underscoring the importance of early and accurate predictive models  to  minimize  complications  and improve  patient  prognosis.  The  Backpropagation  Neural  Network  (BPNN)  has  been widely  utilized  for  heart  disease  prediction;  however,  its  effectiveness  is  highly  dependent  on  the  selection  of  appropriate hyperparameters, including the number of neurons, activation function, optimizer, and batch size. In this study, the influence of  hyperparameter  optimization  on  BPNN  performance  was  investigated.  A  baseline  BPNN  model  was  evaluated  alongside an  optimized  counterpart  in  which  key  hyperparameters  had  been  systematically  fine-tuned  to  improve  both  predictive accuracy  and  model  stability.  Both  models  were  trained  and  validated  using  an  identical  dataset,  and  their  performances were  assessed  based  on  Accuracy,  Precision,  Recall,  Mean  Squared  Error  (MSE),  and  Mean Absolute  Error  (MAE).  The optimized  model  demonstrated  marginally  higher  accuracy  (99.11%  compared  to  99.09%)  and  slightly  lower  error  rates (MSE  and  MAE  of  0.0089  versus  0.0091).  Moreover,  it  achieved  superior  precision,  indicating  enhanced  reliability  incorrectly  identifying  heart  disease  cases.  While  the  performance  improvement  was  relatively  small,  the  optimized  model exhibited greater consistency and balance. These results emphasize the critical role of hyperparameter tuning in enhancing the predictive capability of neural network models in medical applications. The study contributes to the advancement of more accurate  and  dependable  AI-based  tools  for  early  heart  disease  diagnosis.  Future  research  may  benefit  from  employing advanced optimization strategies such as Bayesian Optimization or Genetic Algorithms and leveraging larger, more diverse datasets to improve generalizability.</text>

                <text>Despite the growing sophistication of cyberattacks, current network traffic analysis tools often lack intuitive visual support, limiting human analysts’ ability to interpret complex threat behaviors. To address this gap, this study proposes a novel deep learning-based visualization framework using a Deep Convolutional Generative Adversarial Network (DCGAN) to synthesize threat-specific  infographics  from  structured  numerical  features  in  the  CICIDS2017  dataset.  Unlike  conventional  methods, such as PCA or static dashboards, which often result in abstract or non-adaptive visuals, our approach generates class-distinct grayscale images that preserve the behavioral patterns of various attacks, includingdenial-of-service, brute force, and port scanning. The preprocessing pipeline reshapes the selected flow-based features into 28×28 matrices to train the generative model. Evaluation using the Frechet Inception Distance (FID) yielded a score of 28.4, whereas a CNN classifier trained on the  generated  images  achieved  91.2%  accuracy,  confirming  visual  fidelity  and  semantic  integrity.  Additionally,  a  panel  of human experts rated the interpretability of the generated images at 4.3 out of 5.0. These findings demonstrate that generative visualization can enhance human-centered threat analysis by bridging raw data with interpretable imagery, thereby offering a scalable and explainable approach for integrating AI into real-time security workflows</text>
