Abstract

Every patient who is rushed to the Emergency Department needs fast treatment to determine whether the patient should be inpatient or outpatient. However, the existing fact is that deciding whether an inpatient or outpatient must wait for the diagnosis made by the existing doctor, so if there are many patients, it generally takes quite a long time. So, to predict patient admissions to the emergency unit, a machine learning model that can be fast and accurate is needed. Therefore, this study developed a machine learning and neural network model to determine patient care in Emergency Departments. This study uses publicly available electronic health record (EHR) data, which is 3,309. The model development process uses machine learning methods (SVM, Decision Tree, KNN, AdaBoost, MLPClassifier) and neural networks. The model that has been obtained is then evaluated for its performance using a confusion matrix and several matrices such as accuracy, precision, recall, and F1-Score. The results of the model performance evaluation were compared, and the best model was obtained, namely the MLPClassifier model with an accuracy value = 0.736 and an F1-Score value = 0.635, and the Neural Network model obtained an accuracy value = 0.724 and an F1-Score value = 0.640. The best models obtained in this study, namely the MLPClassifier and Neural Network models, were proven to be able to outperform other models.

Abstract

Pemerintah daerah pelu melakukan persiapan dalam rangka menghadapi Pasar ASEAN, masih banyak peluang UMKM untuk meraih pangsa pasar dan peluang investasi. Guna memanfaatkan peluang tersebut, maka tantangan yang terbesar bagi UMKM di Indonesia menghadapi pasar Bebas ASEAN adalah bagaimana mampu menentukan strategi yang tepat guna memenangkan persaingan. Salah satu solusinya adalah memunculkan produk unggulan dari industri kerajinan tradisional tanah liat yang sampai sekarang masih berkembang dan merupakan warisan budaya bangsa turun-temurun. Kerajinan ini memiliki kearifan lokal yang perlu dijaga kelestariannya. Semula jumlah objek produk penelitian umkm terbagi menjadi 4 jenis yaitu produk tas, pisau, batik, dan tanah liat, tetapi peneliti menemukan beberapa fakta bahwa produk kerajinan dari industri kerajinan tanah liat memiliki banyak jenis produk dan belum pernah masuk dalam kategori produk unggulan daerah di kabupaten kudus, karena itu produk dari tanah liat dijadikan objek  penelitian. Hasil yang diperoleh untuk menentukan prioritas produk kerajinan tanah liat digunakan sistem pendukung keputusan dengan menerapkan metode Technique For Others Reference by Similarity to Ideal Solution (TOPSIS). Pemilihan   Dalam menentukan prioritas produk kerajinan digunakan lima (5) kriteria diantaranya : Jumlah Unit Usaha, Jumlah Tenaga Kerja, Nilai Produksi, Nilai Investasi, Nilai Kompetitif. Hasil dari penelitian ini dapat dijadikan bahan rujukan atau bahan pertimbangan oleh dinas terkait dalam menentukan produk unggulan daerah, khususnya industri tanah liat yang dalam sejarahnya belum pernah menghasilkan salah satu produknya menjadi produk unggulan kabupaten Kudus.

Abstract

The gubernatorial candidate debate was broadcast live streaming through various YouTube channels, which attracted public attention. Many discussions and conversations appeared in the comments section of each YouTube channel that broadcasted the debate. Given the numerous public discussions, it is undoubtedly interesting to analyze the contents of the conversations, as well as the expectations and feedback from the public. However, analyzing conversations in the form of text data will be challenging using conventional methods. Therefore, in this study, public opinion will be analyzed using the topic identification and sentiment classification approaches. Topic identification is conducted to obtain accurate information about what the public is discussing, while sentiment classification is used to determine whether each comment contains positive or negative sentiments. This research is novel because it utilizes data collected from various major media YouTube channels and includes a qualitative analysis of the findings. This study uses public comment data taken from the KPU, NarasiTV, and KompasTV YouTube channels; the results obtained included 4,147 data points. Data preprocessing involves identifying topics using the LDA method, evaluating the LDA model, performing sentiment classification using IndoBERT, and visualizing the results of the public opinion analysis. The results revealed five topics with a perplexity value of -7.7909 and a coherence score of 0.5109. In addition, topic 4 is the most dominant compared to other topics, with 1,146 comments classified as positive sentiment and 504 classified as negative sentiment. Topic 4 reflects how religion, culture, and frequently mentioned figures are perceived and discussed by the public, especially in relation to the gubernatorial election (pilgub) or gubernatorial candidate debates.

Abstract

Exam cheating is a persistent problem facing educational institutions worldwide. This cheating not only harms honest students but also undermines the integrity of the education system. In today's digital age, various forms of cheating are increasingly difficult to detect using manual proctoring methods. For example, test takers can use hidden technological devices or engage in non-verbal communication that is difficult for human proctors to detect. This suggests that traditional proctoring is less effective in addressing increasingly sophisticated cheating. Abstract Exam cheating is a serious problem that can compromise the integrity of the education system. Manual proctoring is often ineffective in identifying suspicious behavior that occurs during exams. This study aims to design and develop a machine learning-based exam cheating detection system with computer vision methods. This system uses facial recognition technology, motion tracking, and object detection to identify suspicious activities such as the use of prohibited devices or unusual movements automatically and in real-time. The method used involves a Convolutional Neural Network (CNN) algorithm for participant face verification, pose estimation for motion analysis, and You Only Look Once (YOLO) for object detection. The results of this system development show that the system can improve efficiency and accuracy in detecting cheating behavior, as well as reduce reliance on manual proctoring.

Abstract

Image improvement is the process to improve visual quality, from the original image to get optimal image results. The first category, this technique operates on the transformation of frequency selection and the second technique operates directly at the pixel level of the image. in this study the Exposure Sub-Image Histogram Equalization (ESIHE) technique will be enhanced with a brightness level to get visual image results. Then ESIHE is compared with other additional techniques, such as Histogram Equalization (HE), Adaptive Histogram Equalization (AHE) from the side of the image. Furthermore, for the even distribution of histograms, we will use ESIHE entropy calculations to show an increase in the image results that are more optimal when compared with HE and AHE. The visual image quality of each technique shows the strength of the method and the superiority of the other methods for various types of images.

Abstract

This research addresses the critical decline in Javanese language usage among younger generations, with only 45% of Central Javanese children actively using the language in daily communication. The study aims to develop and evaluate "Story Adventure of Cakra: Javanese Language," an educational game designed to optimize Javanese language learning for elementary school students aged 7-12 years. The research employed a qualitative methodology involving interviews with students and teachers, participatory observation, and the Game Development Life Cycle (GDLC) framework using Construct 3 engine. The game integrates adventure gameplay mechanics with comprehensive Javanese language instruction, featuring interactive storytelling, script learning modules, cultural elements including unggah-ungguh etiquette and wayang stories, and assessment quizzes. The implementation encompasses four main components: an intuitive user interface with traditional Javanese aesthetics, educational content covering aksara angka, aksara swara, aksara sandangan, and aksara Jawa, engaging adventure gameplay where players control character Cakra to collect script items while avoiding monsters, and comprehensive evaluation systems. Blackbox testing demonstrated 100% functionality validation across all game components, confirming technical reliability and educational effectiveness. The findings reveal that gamification strategies successfully transform traditional language instruction into engaging interactive experiences, bridging conventional teaching methods with contemporary digital learning preferences. This research contributes significantly to educational technology by demonstrating how innovative technological solutions can revitalize interest in regional language preservation while providing measurable learning outcomes for cultural heritage sustainability.
