                <text>The interoperability between electronic health records (EHR) and electronic medical records (EMR) from various healthcare facilities   for   comprehensive   patient   care   is   important.   However,   integrating   such   systems,   including   the   need   for interoperability standards, data privacy, and security, is a highly challenging task, especially since patient rights in data access must  be  considered.  The  primary  problem  addressed  is  the  challenge  of  integrating  electronic  health  records  (EHR)  and electronic medical records (EMR) across various healthcare facilities to ensure comprehensive patient care while maintaining data  privacy, security,  and  adherence  to  patient rights.  This  work  presents  an innovative  application  to consolidate  patient health  records  from  various  medical  facilities.  It  facilitates  seamless  data  access,  improving  the  efficiency  of  healthcare delivery. The GGD approach was used in developing the prototype to ensure the delivered product was able to fulfilthe user requirements. Four  phases  aredivided  into  six  stages  used  in  this  method:  research, modelling,  requirements  definition, framework definition, refinement, and support. The evaluation involved two phases, back-end and front-end testing, utilizing white  box  and  black  box  testing.  Whitebox  testingdelivers  the  average  frame  rendering  rate  of  up  to  56  fps,  and  blackbox testing has shown 100% successful results in the given task. In conclusion, the Med-OID prototype was successfully developed. It  integrates  and  securely  transmits  medical  records  across  various  healthcare  services  well,  demonstrating  significant potential  to  enhance  personalized  medicine  and  healthcare  coordination.  The  evaluations  underscored  the  prototype’s robustness and its capability to improve interoperability and data sharing inhealthcare systems.</text>

                <text>The application of an electronic violation detection system has begun to be implemented in many countries by utilizing CCTV cameras installed at highway and toll road points. However, the development of a violation detection system using data in theform  of  images  that  have  a  high  level  of  accuracy  is  still  a  challenge  for  researchers.  Several  types  of  violations  detected include the use of seat beltsand the use of cell phones while driving which is influenced by the number of vehicles, vehicle speed  and  lightingwhich  can  increase  the  difficulty  in  the  detection  process.  This  research  developed  a  traffic  violation detection system usingYOLO3. The YOLOis used as the basic architecture of CNN which is then combined withLSTM. The dataset was obtained from RoboFlow Universe with a total of 199 front-viewcar images consistingof 82 using seatbelts and 78 not using seatbelts for the training process. The CNN algorithm plays a role in the feature extraction process from input image data, while LSTM plays a role in the prediction process. Furthermore, the performance evaluation of the CNN+LSTM algorithm will be measured using the value of accuracy to measure the performance of the training process and testing process. In measuring the performance of the training process,it will be compared with several basic detection models used, such as CNN,  VGG16,  ResNet50,  MobileNetV2, YOLO3, and YOLO3+LSTM.  The  test  results  show  that YOLO3+LSTM  has  higher accuracy compared to the others at 89%. Next, in the testing process, the CNN+LSTMmodel will be compared with the basic method,  namely  CNN.  The  test  results  show  that  the  CNN+LSTM  models havehigher  accuracy  at  89%.  Meanwhile,  in  the basic CNN model, the resulting accuracy was 85%</text>

                <text>Remote Sensing Scene Classification (RSSC) is the discrete categorization of remote sensing images into various classes of scene categories based on their image content. RSSC plays an important role in many fields, such as agriculture, land mapping, and  identification  of  disaster-prone  areas.  Therefore,  a  reliable  and  accurate  RSSC  algorithm  is  required  to  ensure  the accuracy  of  land  identification.  Many  existing  studies  in  recent  years  have  used  deep  learning  methods,  especially  CNN combined with attentionmodules to solve this problem. This study focuses on solving the RSSC problem by proposing a deep learning-based method (CNN) with a ConvNeXt-Tiny model integrated with the Efficient Channel AttentionModule (ECANet)and label smoothing regularization (LSR).The ConvNeXt-Tiny model shows that a persistent superior outperforms the ‘large’ model  in  convinced  metrics.ConvNeXt-Tiny  model  also  has  a  huge  advantage  in  high-precision  positioning  and  higher classification accuracy and localization precision in a variety of complicated scenarios of remote sensing scene recognition.Experiments in this study also aim to prove that the integration of the attention module and LSR in the basic CNN network can improve accuracy because the attention module can strengthen important features and weaken features that are less useful for classification. The experimental results proved that the integration of ECANetand LSR in the ConvNeXt-Tiny base network obtained a higher accuracyof 0.38% in the UC-Merced dataset, 0.7% in the AID, and 0.4% in the WHU-RS19dataset than the ConvNeXt-Tiny model without ECANetand LSR. The ConvNeXt-Tiny model with ECANetintegration and LSR obtained an Accuracyof 99.00±0.41% in the UC-Merced dataset, 95.08±0.20% in AID, and 99.50±0.31% in the WHU-RS19 dataset</text>

                <text>Heart disease is a majorproblem that must be overcome for human life. In recent years, the volume of medical data related to heart disease has increased rapidly, and various heart disease data have collaborated with information technology such as machine learning in detecting, predicting,and classifying diseases.This research aimsto improve the performance of machine learning  classification  methods,  namely  K-Nearest  Neighbor  (KNN)  and  Decision  Tree  (C4.5)  with  the particle  swarm optimization(PSO) feature in cases of heart disease. In this research, a comparison was made of the performance of the PSO-based  K-NN  and  C4.5  algorithms. Following  experiments  employing  PSO  optimization  to improvethe  K-NN  and  C4.5 algorithms, the findings indicated that the K-NN algorithm performed exceptionally well with PSO, achieving an accuracy of 89.09%, precision of 89.61%, recall of 90.79%, and an AUC value of 0.935</text>

                <text>Deep learning is an artificial intelligence technique that has been used for various tasks. The performance of deep learning is determined by its hyperparameter, architecture as well as training (connection weight and bias). Finding the right combination of those aspects isvery challenging. Convolution Neural Networks (CNN) is a deep learning method that is commonly used for image  classification.  It  has  many hyperparameterstherefore  tuning  its  hyperparameter  is  difficult.  In  this  research, a metaheuristics  approach  is  proposed  to optimisethe  hyperparameter  of  convolution  neural  networks.  Threemetaheuristics methodsare  used  in  this research,  ant colony  optimization  (ACO,)  genetic  algorithm  (GA)and  Harmony  Search  (HS).  Themetaheuristics methods are usedtofind the best combination of8 hyperparameterswith 8 optionseach which creates1.6. 107 ofsolution space.The solution space is too big to explore using manual tuning. The Metaheuristics method willbring benefitsin termsof finding solutions in the search space more effectively and efficiently.The performance of the metaheuristics methodsisevaluated using MNIST datasets. The experiment resultsshow that theaccuracy of ACO, GA and HS are 99,7%, 97.7% and 89,9% respectively. The computationaltime for the ACO, GA and HS algorithmsare 27.9 s, 22.3 s and 56.4 srespectively. It showsthat ACO performsthe best among the three algorithmsin termsof accuracy however its computational time is slightly longer than GA.The experiment results revealthat themetaheuristic approach is promising for the hyperparameter tuning of CNN.Future  research  can  be  directed  to  solve  larger  problems  or enhancethemetaheuristics  operator  to  improve  its performance</text>

                <text>Despite being in high demand as a lifelong learner and academic material supplement, the implementation of Massive Open Online Courses(MOOC) has problems, one of which is the dropout rate (DO) of students which reaches 93%. As one of the solutions to this problem, Machine Learning can be utilized as a risk management and early warning system for students who have the potential to drop out. The use of ensemble techniques to build models can improve performance, but previous research has not reviewed the most optimal ensemble technique for this case study. As a form of contribution, this study will compare the  performance  of  models  built  from  stacking  and  blending  techniques.  The  algorithms  used  in  the  base  model  are  KNN, Decision Tree, and Naïve Bayes, while the meta-modeluses XGBoost. These algorithms are used to build models with stacking and blending techniques. The experimental results using stacking are 82.53% accuracy, 84.48% precision, 94.12% recall, and 89.04% F1-Score. Meanwhile, blending obtained 83.39% accuracy, 85.31% precision, 94.21% recall, and 89.54% F1-Score. These results are supported by model testing using k-fold cross-validationand confusion matrix techniques which show the same results. That is, blending is 0.86% higher than stacking so it can be concluded that blending has better performance than stacking in the MOOC student dropout prediction case study</text>

                <text>Problems with small sample sizesand high dimensionality are common in pattern recognition.Almost all machine learning algorithms  degrade  in  high-dimensional  data,  so  thatsingularities  in  the  scatter  matrices,  the  main  problem  of  the  Linear Discriminant  Analysis  (LDA)  technique,  might  result.A  null  space-based  LDA  (NLDA)  has  been  conceived  to  address  the singularity issue. NLDA aims to maximize the distance between classesin the null space of the within-class scatter matrix.In the  earliest  research,  the  NLDA  method  was  performed  by  computing  eigenvalue  decomposition  and  singular  value decomposition  (SVD).  This  research  led  to  several  new  implementations  of the NLDA  method  using  other  matrix decompositions.The new implementations include NLDA using Cholesky decomposition and NLDA using QR decomposition. This paper compares the performance of three NLDA methods using different matrix decompositions, namely SVD, Cholesky decomposition,  and  QR  decomposition.Two  sets  of  data  were  used  in  the  experiments  that  used  three  different  NLDA algorithms.To determine the performance of the NLDA methods, the classification accuracy of the three methods was measuredusing the Confusion Matrix. The results show that the NLDA method using SVD has the best performance when compared to the other two methods, achieving 77.8% accuracy for the Colon dataset and 98.8% accuracy for the TKI-resistance dataset</text>

                <text>The software development cycle involves testing and deployment stages that can be laborious and time-consuming, especially in collaborative projects that involve several developers. Implementing Continuous Integration (CI) and Continuous Delivery (CD)  offers  a  solution  to  streamline  this  process.  This  study  presents  a  case  study  of  the  Cloversy.id  RESTful  API  project, highlighting challenges encountered during development and the implementation of a new system using GitHub Actions as the DevOps tool. The research resulted in the adoptionof a new system, replacing the conventional practices previously employed by  the  Cloversy.id  development  team.  Employing  flowcharts,  the  study  meticulously  mapped  out  the  development  flow, pinpointing bottlenecks and areas for optimization within the cycle. Notably, the implementation of a CI/CD pipeline resulted in a notable improvement, with a 35% increase in speed for CI and a remarkable 39% enhancement for CD. GitHub Actions played a pivotal role in automating critical tasks, reducing reliance on manual intervention, and minimizing dependency on team leaders. The platform's features, including detailed logs and email notifications, empowered team leaders and developersalike to take informed actions swiftly. Furthermore, the study highlights the noveltyof integrating CI/CD by considering factors such as branching strategy, code review practices, testing methodologies, deployment methods, and infrastructure</text>

                <text>Recurrent Neural Network is a Deep Learning algorithm that is commonly used to develop prediction systems. There are many variants of RNN such as RNN itself, Long Short Term Memory (LSTM), and Gated Recurrent Unit, so it is frequently debatable which algorithm from the RNN family has the most optimal efficiency and computation time. When developing a prediction system, sequential data or time-series data is required so that an accurate prediction can be made. Sequential or time-series data  involves  data  arranged  in  time  sequence,  such  as  weather  data,  financial  data,  carbon  emission  data  and  traffic  data recorded over time. This research will be carried out by predicting the three RNN models against historical Bitcoin value data. The research method used is Experimental Design by comparing the performance between the three models on bitcoin value time series data, testing is done by involving hyperparameters such as Tanh, Sigmoid and ReLU activation functions, batch size, and epochs. The aim of this research is to find out which RNN model can produce the most optimal performance andfind out what performance measurescan be used to evaluate and compare the performance between the three models. The results of the study show that LSTM is the most effective model with RMSE 0.012441 and MSE 0.000155 but inefficient because it takes 3 minutes 24 seconds to run the computation, in the meantime Tanh activation function gives the most optimal prediction than  Sigmoid  and  RelU  and  therefore  should  be  the  main  candidate  to  be  used  with  RNN  models  when  predictingBitcoinprices</text>

                <text>Software  House  XYZ  employs  Scrum  as  one  of  its  software  development  processes.  However,  the  company  faces  several challenges in the implementation of Scrum, leading to delays in their product releases. Two specific problems are the control of  a  large-scale  Scrum  team  and  the  management  of  team  commitments.  In  addressing  these  issues,  the  Scrum  at  Scale framework has been chosen as a solution. Before implementing Scrum at Scale, an assessment of the current Scrum maturity level at Software House XYZ is deemed necessary.The Scrum Maturity Model, adapted to the Scrum Guide 2020, is selected as the method to evaluate how effectively the company is implementing Scrum. A questionnaire comprising 81 practices was distributed to development teams, with 10 valid responses collected. Based on the assessment using the Scrum Maturity Model, the  current  Scrum  implementation  maturity  at  Software  House  XYZ  is  rated  at  level  1,  Initial.  A  total  of 61practices  are proposed  for  improvement  in  the  Scrum  process.Scrum  at  Scale  can  be  implemented  once  the  suggested  Scrum  process improvements have been made. These recommendations are structured following the framework outlined in the Scrum at Scale Guide  2022.  Validation  of  the  Scrum  at  Scale  recommendations  has  been  conducted  by usthrough interviews  with representatives from Software House XYZ. From the validation results, the company expresses interest in trying to implement Scrum  at  Scale.  However,  the  company  agrees  to  enhance  the  existing  Scrum  process  within  the  organization  before  fully adopting Scrum at Scale</text>
