                <text>Diabetes is a metabolic disorder characterized by blood glucose levels above normal limits.Diabetes occurs when the body is unable to produce sufficient insulin to regulate blood sugar levels. As a result, blood sugar management becomes impaired and there is no cure for diabetes.Early detection of diabetes provides an opportunity to delay or prevent its progression into acute stages.Clustering can help identify patterns and groups of diabetes symptoms by analyzing attributes that indicate these symptoms.  In  this  study,  researchersare  using  K-Medoid  and  Quantum  K-Medoid  methods  for  clustering  diabetes  data.Quantum  computing  utilizes  quantum  bits,  or  qubits,  which  can  represent  multiple  states  at  the  same  time.  Compared  to classical  computers,  quantum  computing  has  the  potential  for  an  exponential  speedup  in problem-solving.Researchers conducted a comparison between two methods: the classic K-Medoids method and the K-Medoids method utilizing quantum computing.  The researchers found that both Quantum K-Medoid and Classic K-Medoid achieved the same clustering accuracy of 91%.In testing with the Quantum K-Medoids algorithm, it was found that the cost value in the 8th epoch showed a significant decrease  compared  to  the  Classical K-Medoids  algorithm.This  demonstrates  that  Quantum K-Medoid can  be  considered  a viable alternative for clustering purposes</text>

                <text>The pervasive issue of fake news spreading rapidly on online platforms.causing a concerning dissemination of misinformation. The influence of fake news has become a pressing social problem, shaping public opinionin important eventssuch as elections. This research focuseson detectingand classifyingfake newsusing the Random Forest algorithm by investigating the impact of  feature  extraction  techniques  on  classification  accuracy,  this  study  specifically  employs  theTF-IDF  method.  For  this purpose, we used 44,898 English-language articles from the ISOT fake news dataset. The dataset is cleaned using tokenization and stemming then split into 75% training and 25% testing. The TF-IDF vectorizer technique was applied to convert text into numeric  as  feature  extraction.  This  study  has  implemented a Random  Forest  classifier  to  predict  real  and  fake  news.  The proposed model contributes to overall classification precision by comparing it to the existing models. This fake news detectionhighlights the efficacy of the TF-IDF vectorizer and Random Forest combination whichachieved an impressive accuracy rate of 99.0%.This contribution highlights an effective strategy for combating misinformation through precise text classification</text>

A dataset of 12,480images was used, with preprocessing steps such as binarization and normalization to improve segmentation accuracy.  Results  show  that  Ghost  U-Net  achieved  a  marginally  higher  performance,  with  an  IoU  of  0.5041  and  a  Dice coefficient  of  0.6664,  compared  to U-Net’s IoU of 0.5034 and Dice coefficient of 0.6662. Ghost U-Net  also  demonstrated significant  memory  efficiency,  reducing  GPU usage  by  up  to  60%  in  FP16  and INT8 formats.  However,  a  sharp  decline  in performance was observed for Ghost U-Net in the INT8 format, where the IoU dropped to 0.2038 and the Dice coefficient to 0.3227,  whereas  U-Net  maintained  stable  performance  across  all  formats.  These  findings  suggest  that  Ghost  U-Net  is preferable  for  applications  prioritizing  memory  efficiency  and  inference  speed,  while  U-Net  may  be  better  suited  for  tasks requiring consistent accuracy across different quantization levels. This study underscores the importance of considering bothperformance stability and memory efficiency when selecting models for deployment in real-world application</text>

                <text>The  rapid  advancement  of  Internet  of  Things  (IoT)  technology  has  created  potential  for  progress  in  various  aspects  of  life. However, the increasing number of IoT devices also raises the risk of cyberattacks, particularly IoT botnets often exploited by attackers. This is largely due to the limitations of IoT devices, such as constraints in capacity, power, and memory, necessitating an  efficient  detection  system.  This  study  aims to  develop  a  resource-efficient  botnet  detection  system  by  using  the  Self-Organizing  Feature  Map  (SOFM)  dimensionality  reduction  method  in  combination  with  machine  learning  algorithms.  The proposed  method  includes  a  feature  engineering  process  using  SOFM  to  address  high-dimensional  data,  followed  by classification with various machine learning algorithms. The experiments evaluate performance based on accuracy, sensitivity,specificity, False Positive Rate (FPR), and False Negative Rate (FNR). Results show that the Decision Tree algorithm achieved the  highest  accuracy  rate  of  97.24%,  with  a  sensitivity  of  0.9523,  specificity  of  0.9932,  and  a  fast  execution  time  of  100.66seconds. The use of SOFM successfully reduced memory consumption from 3.08GB to 923MB. Experimental results indicate that this approach is effective for enhancing IoT security in resource-constrained devices</text>

                <text>The increase in population impacts several environmental sectors, particularly the use of natural gas energy for household  needs,  such  as  LPG  (Liquefied  Petroleum  Gas).  This  has  resulted  in  the  depletion  of natural  gas reserves  and  a  rise  in  LPG  imports.  Additionally,  the  growing  population  contributes  to  the  accumulation  of household waste, which can lead to  excessive leachate production  and greenhouse gas emissions. This issue is particularly  concerning  in developing  countries  like  Indonesia  due  to  its  negative  environmental  impact. This research aims to provide a solution and contribute to reducing household waste accumulation by utilizing organic waste to create renewable energy in the form of biogas as analternative to LPG.Biogas is produced through the fermentation   of   organic   waste.   Nutrient-rich   fluids   containing   sugar   can   enhance   the   performance   of methanogenic  bacteria  in  biogas  formation.  In  this  study,  we  conducted  nutritional  testing  on molasses  and coconut water to determine which nutrients optimize biogas production efficiency by monitoring the pressure of the  generated  biogas.  Generally,  biogas  comprises  methane  and  carbon  dioxide.  It  is  important  to  note  that excessive  methane  can  lead  to  explosions,  while  high  carbon  dioxide  levels  contribute  to  greenhouse  gas emissions. The quantities of methane and carbon dioxide produced during biogas generation can be influenced by temperature and humidity. Therefore, monitoring pressure, temperature, humidity, methane, and carbon dioxide levels  in  the  biogas  production  process  using  the  Internet  of  Things  (IoT)  is  a  prudent  approach.  The  results indicate that a substrate mixed with molasses produces biogas at twice the pressure compared to coconutwater. Furthermore,  optimal  biogas  production  with  ideal  methane  and  carbon  dioxide  levelsoccurs  at  temperatures between 25-35°C under high humidity conditions. This suggests that mesophilic methanogenic bacteria thrive in tropical climates</text>

                <text>This research seeks to construct an automatic translation between Indonesian and Sundanese languages based on the Neural Machine Translation (NMT) method. The model used in this study is the Long Short-Term Memory (LSTM) type, which carries out an encoder-decoder structure model learned with Bible data. The text translation here was conducted in different epochs to optimize the process, followed bythe Adam optimization algorithm. Testing the Adam optimizer with different epoch settings yields a BLEU score for Indonesian to Sundanese translations of 0.991785, higher than the performance of the None optimizer. Experimental  results  demonstrate  that  Indonesian  to  Sundanese  translation  using Adam  optimization  with  1000  epochs consistently performed better in BLEU -Bilingual Evaluation Understudy -scoring thanSundanese to Indonesian translation. Limitations of the research were also put forth, particularly technical issues related to the collection of data and the Sundanese language’s complex grammatical features, that the model can onlypartially express, honorifics, and the problem of polysemy. Also, it mustbe mentioned that no special hyperparameter selection was performed, as parameters were chosen randomly. In future studies, transformer-based models can be investigated since these architectures will better dealwith complex language via their self-attention mechanism.</text>

                <text>Accurately  identifying  facial  skin  types  is  essential  for  recommending  the  right  skincare  treatments  and  products. Misidentifying  skin  types  can  lead  to  negative  consequences,  such  as  irritation  or  worsening  of  skin  conditions.This  study investigated methods for classifying facial skin types into five categories: oily, acne-prone, dry, normal, and combination. A dataset  of  1725  augmented  facial  images  was  used.  Data  augmentation  techniques  likely  increased  the  dataset's  diversity, which helps improve the model's generalization ability. The data underwent preprocessing, including rescaling, before being applied to two deep learning models, CNN and MobileNetV3. The models were evaluated based on accuracy and execution time to determine the most effective approach for classifying facial skin types.The CNN model achieved an accuracy of 64%, demonstrating its potential for image classification tasks. However, the MobileNetV3 model significantly outperformed CNN with an accuracy of 84%. This superior performance is attributed to MobileNetV3's advanced architecture, which is optimized for  efficient  feature  extraction, and particularly  relevant  for  capturing  the  subtle  variations  in  facial  skin  types.  Therefore, MobileNetV3 emerged as the more effective method for classifying facial skin types with higher accuracy.</text>

                <text>This research aims to develop a memory-efficient face recognition system for a receptionist robot using the Local Binary Patterns Histogram (LBPH) algorithm. Given the computational limitations of the Raspberry Pi, the system utilizes  optimization  techniques  including  grayscale  conversion,  noise  reduction,  and  contrast  adjustment  to enhance processing efficiency. Testing demonstrates that the face recognition accuracy achieves 80.5% to 85.5% in  offline  mode,  and  72%  to  81%  in  real-time  mode,  with  variations  due  to  lighting  conditions  and  facial expressions.  The  robot's  servo  motors  exhibit  a  response  time  between  1.945  and  3.561  seconds,  enabling responsive and interactive user engagement. The results suggest practical benefits for deploying face recognition in resource-constrained environments, enhancing the efficiency of robotic receptionist applications.</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>

                <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>
