                <text>In the field of skin cancer classification, machine learning and deep learning have been extensively utilized, particularly with convolutional  neural  network  (CNN)  architectures.  However,  there  remains  room  for  exploration  to  achieve  optimal performance.  This  study  investigates  the  use  of  the  MobileNetV3Large  architecture  for  transfer  learning,  chosen  for  its efficiency  in  low-power  and  memory-constrained  applications.  To  further  enhance  performance,  black-hat  morphological transformation and oversampling techniques were applied to the ISIC 2020 dataset. Additionally, mixed precision training was implemented to reduce training time. The research aimed to compare the accuracy, precision, recall, F1-score, and training time of models trained with and without mixed precision. The findings revealed that while the model without mixed precision achieved superior performance with accuracy, precision, recall, and F1-score metrics reaching 98%, both models yielded an AUC-ROC of 1. Notably, mixed precision training significantly reduced training time by 1,646 seconds (27 minutes and 26 seconds), representing an 8.39% speed increase. These results suggest that mixed precision can meaningfully accelerate model training while maintaining competitive performance. The practical implications of this research include its potential to improve the efficiency of skin cancer classification models, making them more suitable for real-time clinical applications, particularly in resource-constrained environments</text>

                <text>Palm oil plantations in Indonesia face challenges in enhancing productivity and profitability, notably due to pest attacks that reduce  production.  Early  identification  and  classification  of  plant  conditions,  particularly  palm  oil  leaves,  are  crucial  for mitigating  losses.  This  study  explores  the  application  of  artificial  intelligence,  specifically  computer  vision  and  machine learning,  for  disease  detection.  Various  machine  learning  techniques,  including  Local  Binary  Pattern  (LBP),  K-Nearest Neighbors  (KNN),  and  Support  Vector  Machine  (SVM),  have  been  used  in  different  studies  with  varying  accuracy.  This research  focuses  on  modifying  Particle  Swarm  Optimization  (PSO)  for  feature  selection  in  identifying  diseases  in  palm  oil leaves.  The  PSO  modification  combined  with  logistic  regression  and  Bayesian  Information  Criterion  (BIC)  significantly enhances  KNN  performance.  Accuracy  improved  from  95.75%  to  97.85%,  while  precision,  recall,  and  F1-score  reached approximately  98.80%.  Additionally,  the  modified  KNN+PSO  achieved  the  shortest  computation  time  of  0.0872  seconds, indicating high computational efficiency. These results demonstrate that the PSO modification not only improves accuracy but also  computational  efficiency,  making  it  an  effective  method  for  enhancing  KNN  performance  in  detecting  palm  oil  leaf diseases</text>

                <text>The  performance  of  XYZ,  a Government  Higher  Educational  Institution  (GHEI)  in  Indonesia  is  assessed  through  two unintegrated  applications. The  2023  targetperformancewas  missed  due  to  miscalculations outside applicationswhiletransforminglarge data amounts. Thus,business intelligence (BI) serves as a knowledge management (KM) toolto integratethoseapplicationsto achieveXYZ'starget. BecauseBI is costly and 70% failure rate of developmentplans, a research model was  evaluated  to look  at currentXYZ innovation  capabilityfor  successful  BI  adoptionfrom the KM  foundation  and  KM solutions implementation. Thisstudy useda quantitative method, employinga questionnaire for 94 civil servantsand the partial least squares-structural equation model (PLS-SEM) for data analysis. Results indicate in the KM foundation,organizational (O) negatively influences KM process application (KMP)(β = -0.292,Pv = 0.010)while KM infrastructure (I)and process (P)positively influence KMP,butKM technology (T)does not.In KM solutions,KMP is provenlinked to innovation capability whenKM systemsarelacking.Hence,severalactivitiesare suggestedto activateTthrough T, O, P, and I.

                <text>Visitor reviews play a crucial role in determining the success of a business, particularly those offering hospitality and services, such as hotels. The growth of internet technology has made it easier for guests to share their experiences, which can influence potential  customers.  Google  Maps  is  one  of  the  platforms  used  for  giving  and  searching  reviewsThis  research usesdata crawled from Google Maps Review using the playwright library. However, the large volume of reviews can make analysis and topic-based  categorization—such  as  service  quality,  hotel  location,  and  operational  hours—challenging.  To  address  this, DBSCAN is used to cluster reviews based on these topics. Clustering helps improve sentiment classification, making it more targeted and allowing a comparison of two machine learning algorithms: Naïve Bayes and Support Vector Machine (SVM). Naïve Bayes achieved higher accuracy(0.87) in the operational hours cluster, while SVM scored 0.78. However, SVM showed improved accuracy in the location (0.89) and service (0.88) clusters, with Naïve Bayes maintaining a stable 0.86 accuracy in both. Both models demonstrated an average training time of less than one second, excluding preprocessing.</text>

                <text>This  research  aims  to  apply  pattern  recognition  technology,  specifically  through  the  Convolutional  Neural  Network  (CNN) approach, in identifying and translating Sundanese script accurately. This research is focused on recognizing rarangken script patterns  based  on  ngalagena  script  in  Indonesian  cultural  heritage.  This  study  uses  the  MobileNetV2based  CNN  model, utilizing transfer learning and trained for 50 epochs using the Adam optimizer with a learning rate of 0.0001, to achieve a training accuracy of 98.75% and test accuracy of 96.95% in 1 hour and 23 minutes, respectively. The results of the study show that the simpler CNN architecture without augmentation achieved the highest accuracy of 99.26%, and the augmented CNN model achieved 94.42% accuracy in 2 hours and 22 minutes. These results enable practical applications in both education and cultural  preservation,  demonstrating  how  modern  technology  can  effectively  contribute  to  maintaining  traditional  cultural elements in the digital era</text>

                <text>anana  leaf  diseases  such  as  Sigatoka,  Cordana,  and  Pestalotiopsis  pose  a  significant  threat  to  banana  productivity,  with implications for food security and the global economy. Early detection of this disease is an important step to reduce its spread and maintain crop yield stability. This research utilizes the Convolutional Neural Network (CNN) method to detect banana leaf diseases based on image analysis of infected and healthy leaves. The dataset used includes 937 images consisting of four maincategories, namely healthy leaves, Sigatoka, Cordana, and Pestalotiopsis. The dataset is processed through augmentation to increase data diversity and quality. The CNN model was applied for classification, with evaluation results reaching 92.85% accuracy, 95.73% recall, 93.52% precision, and 94.60% F1-score. This research contributes to the development of Artificial Intelligence-based  technology  for  applications  in  the  agricultural  sector,  especially  in  supporting  farmers  to  detect  banana leaf diseases quickly, accurately and efficiently. The research results also provide recommendations for exploring additional data augmentation and increasing dataset variety to improve model detection performance in the future. This shows CNN's potential to supportsustainable agriculture in the modern era</text>

                <text>Indonesia’s frequent earthquakes, caused by its position at the convergence of multiple tectonic plates,Indonesia's frequent earthquakes, caused by its position at the convergence of multiple tectonic plates, necessitate precise seismic zone identification to  improve  disaster  preparedness.  This  research  evaluates  the  effectiveness  of  five clustering  algorithms—K-Medoids,  K-Means, DBSCAN, Fuzzy C-Means, and K-Affinity Propagation (K-AP)—for analyzing earthquake data from January 2017 to January  2023.  Using  a  dataset  from  BMKG  encompassing  13,860  seismic  events,  each  algorithm  was  assessed  based  on Silhouette Score and Cluster Purity metrics. Results indicated that K-Means provided the best balance, forming six clusters with a Silhouette Score of 0.3245 and Cluster Purity of 0.7366, making it the most suitable for seismic zone analysis. K-Medoids closely followed with a Silhouette Score of 0.3158 and Cluster Purity of 0.7190. Although DBSCAN effectively handled noise, its  negative  Silhouette  values  indicated  poor  clustering  quality.  Fuzzy  C-Means  and  K-AP  underperformed,  with  K-AP generating animpractically high number of clusters (196) and the lowest Silhouette Score (0.2550). This study offers a novel, comprehensive  comparison  of  clustering  algorithms  for  Indonesian  earthquake  data,  emphasizing  a  dual-metric  evaluation approach.  By  identifying  K-Means  as  the  most  effective  algorithm,  provides  valuable  insights  for  disaster  mitigation  and seismic risk analysis</text>

                <text>Human health depends on choosing food ingredients that align with dietary needs and avoid allergens. However, consumers often encounter unfamiliar ingredients that require additional information. Traditionally, they search online by typing in the ingredient's name which can be time-consuming and may not yield relevant results. Therefore, a system to identify and display ingredient information is necessary. This studyproposesa new system that identifies ingredients by scanning the composition label on packaging using PaddleOCR and retrieving information through ChatGPT on a smartphone. The process begins with capturing an image of the composition label.ThenPaddleOCR is employed to extract text from the scanned label, enabling identification of the listed ingredients. Subsequently, ChatGPT retrieves detailed information about the desired ingredients and displays it, allowing users to easily understand the ingredients. The system's effectiveness in text recognition is assessed using the character error rate (CER). The results show robustperformance by achieving an average CER of 0.14, with flat packaging reaching  an  impressive  CER  of  0.05.  Additionally,  the  system's  usability  was  assessed  through  pilot  testing  which received significant positive user feedbackachieving a 4.37 satisfaction level on the Likert scale, particularly regarding the clarity and relevance of the ingredient information provided</text>

                <text>Student feedback plays a crucial role in enhancing the quality of educational programs, yet analyzing this feedback, especially in informal contexts, remains challenging. In Indonesia, where student comments often include colloquial language and vary widely in content, effective multilabel classification is essential to accurately identify the aspects of courses being critiqued. Despite the development of several BERT-based models, the effectiveness of these models for classifying informal Indonesian text  remains  underexplored.  Here  we  evaluate  the  performance  of  three  BERT  variants—IndoBERT,  IndoBERTweet,  and mBERT—on  the  task  of  multilabel  classification  of  student  feedback.  Our  experiments  investigatethe  impact  of  different sequence  lengths  and  truncation  strategies  on  model  performance.  We  find  that  IndoBERTweet,  with  a  macro  F1-score  of 0.8462, outperforms IndoBERT (0.8243) and mBERT (0.8230) when using a sequence length of 64 tokens and truncation at the  end.  These  findings  suggest  that  IndoBERTweet  is  well-suited  for  handling  the  informal,  abbreviated  text  common  in Indonesian student feedback, providing a robust tool for educational institutions aiming for actionable insights from studentcomments.</text>

                <text>In the digital age, the security of communication technologies is paramount, with cybercrime projected to reach $10.5 trillion annually by 2025. While encryption is vital, decrypted data remains vulnerable, prompting the exploration of steganography as an additional security layer. Steganography conceals data within digital media, but its misuse for cyberattacks—such as embedding malware—has highlighted the need for steganalysis, the detection of hidden data. Despite extensive research, few studies have explored lightweight deep-learningmodels for real-time steganalysis in resource-constrained environments like mobile  devices.  This  research  evaluates  MobileNet,  ShuffleNet,  and  EfficientNet  for  such  tasks,  using  the  BOSSbase-1.01 dataset.  Models  were  assessed  based  on  accuracy,  computational  efficiency,  and  resource  usage.  MobileNet  achieved  the highest computational speed but with only 63.8% accuracy, falling short of practical application. ShuffleNet and EfficientNetperformed at random-guessing levels with50% accuracy, reflecting the challenges of steganalysis on mobile platforms. Future work  aims  to  improve  accuracy  by  integrating  advanced  preprocessing  techniques,  attention  mechanisms,  and  hybrid architectures,  as  well  as  leveraging  ensemble  methods  for improved  detection.  Data  augmentation,  transfer  learning,  and hyperparameter  tuning  will  also  be  explored  to  optimize  model  performance.  This  study  contributes  by  identifying  these challenges and offering insights for future research, focusing on optimizing models and preprocessing techniques to enhance detection accuracy in resource-constrained environments</text>
