APPLICATION OF CONVOLUTIONAL NEURAL NETWORKS (CNN) FOR HEPATITIS C VIRUS (HCV) DISEASE DETECTION
type: item
description: Hepatitis C (HCV) is a serious liver infection that can progress to cirrhosis or cancer, especially if early diagnosis is neglected. While conventional diagnostic methods such as ELISA are accurate, they are often limited in terms of efficiency and accessibility. This study introduces an innovative approach using a one-dimensional convolutional neural network (1D-CNN) for HCV disease classification, utilizing a Kaggle dataset consisting of 615 patient samples. The methodology includes data preprocessing such as handling missing values ​​and transforming categorical variables to numeric values ​​to ensure data readiness. The 1D-CNN model was trained using the Adam optimizer with ReLU activation functions in the convolution layer and sigmoid in the output layer. Model performance was comprehensively evaluated through accuracy, precision, recall, and F1-score metrics. The results showed that the 1D-CNN model achieved an accuracy of 83.74% on the training data and 81.30% on the testing data after hyperparameter tuning. This improvement is significant compared to the initial accuracy of only around 52%. However, the model exhibits a strong bias towards the majority class (Blood Donor), with very poor performance on minority classes such as Hepatitis, Fibrosis, and Cirrhosis. Nonetheless, this study contributes to the exploration of 1D-CNN for non-image medical data, which is still rarely studied. We conclude that despite the model's potential, further developments such as data balancing are needed to improve the model's overall generalization and accuracy.

CROWDFUNDING WEBSITE SECURITY THROUGH POLYGON BLOCKCHAIN TECHNOLOGY IMPLEMENTATION
type: item
description: This study aims to enhance the security and transparency of crowdfunding platforms by implementing Polygon blockchain technology. Traditional crowdfunding systems are often vulnerable to fund mismanagement and lack accountability. To address these issues, a blockchain-based crowdfunding website was developed using smart contracts deployed on the Polygon network. The project follows a software engineering approach using the prototyping development model. The system is built using Solidity for smart contracts and React.js for the frontend, integrated with the MetaMask crypto wallet for authentication and transaction execution. The implementation results show that the system successfully facilitates secure, transparent, and decentralized donation processes. All transactions and fund flows are permanently recorded and verifiable through PolygonScan. User validation is conducted without conventional login systems, relying instead on wallet-based authentication, which reduces the risk of credential theft. Functional testing confirms that all core features perform as expected, including donation program selection, transaction history recording, and MetaMask integration. In conclusion, the developed system successfully achieves the research objective of providing a more secure and trustworthy crowdfunding platform through the application of Polygon blockchain technology.

This research aims to develop an automated mushroom classification system based on the Random Forest algorithm to distinguish between edible and poisonous mushrooms. It leverages all 21 attributes (18 categorical, 3 numerical) from a compr[1]ehensive Kaggle dataset comprising 61,069 entries. The research methodology follows a modified CRISP-DM workflow, from data collection through to implementation. Crucial data preprocessing steps were extensively performed, including handling data duplicates and imputing missing values (using median and mode). Subsequently, class labels were transformed (edible=0, poisonous=1), and One-Hot Encoding was applied to categorical features for appropriate numerical representation. Numerical features such as cap-diameter and stem-height were normalized using Standard Scaling to balance their contributions. The data was then split 80:20 for training and testing. The Random Forest model was developed with optimal parameters (n_estimators=200, max_depth=15, class_weight="balanced") for efficiency and robustness against class imbalance. Evaluation results demonstrated excellent performance with an overall accuracy of 99.34%, along with balanced precision, recall, and F1-score values of 0.99 for both classes. Feature importance analysis identified stem-width, stem-height, and cap-diameter as the most influential attributes. The learning curve indicated model stability without significant overfitting. Implementation on new mushroom samples also confirmed consistent predictive capability, making this model suitable as an automated decision support system for detecting poisonous mushrooms.

ANALISIS PROGRAM MAKAN BERGIZI GRATIS DENGAN SUPPORT VECTOR MACHINE (SVM) PADA APLIKASI X
type: item
description: The Free Nutritious Meal Program (MBG), which represents a priority program of President Prabowo Subianto, has garnered widespread attention from Indonesian society. This program has received sympathy from various groups, including students and informal workers, and has been extensively discussed through social media, particularly on platform X. This research aims to analyze public response in the form of positive and negative sentiment toward the MBG Program based on data from platform X. A total of 1,378 tweets were collected using crawling methods, followed by preprocessing, sentiment labeling using the InSet lexicon dictionary, and feature extraction using three techniques: Term Presence, Bag of Words (BoW), and Term Frequency-Inverse Document Frequency (TF-IDF). Subsequently, sentiment classification was performed using the Support Vector Machine (SVM) algorithm for each feature extraction technique. Classification results demonstrate that the TF-IDF technique achieved the highest accuracy of 77.5%, compared to Term Presence (76.2%) and BoW (75.3%). Validation using K-Fold Cross Validation with five iterations was conducted with imbalanced data handling through the Synthetic Minority Over-sampling Technique (SMOTE) method. In this validation, TF-IDF consistently demonstrated superior performance with an average accuracy of 75.54%, precision of 74.31%, recall of 73.86%, and f1-score of 73.98%. Despite a slight decrease in accuracy following data synthesis, the TF-IDF technique proved to be stable and effective in handling data variation. The superiority of the TF-IDF feature extraction technique is suitable for combination with the SVM algorithm. Keywords: Free Nutritious Meal Program, SVM algorithm, TF-IDF, Platform X, SMOTE Method

GAUSSIAN NAÏVE BAYES CLASSIFIER METHOD FOR CLASSIFYING FAST FOOD CONSUMPTION AT THE LEVEL OF OBESITY RISK
type: item
description: The increasing prevalence of obesity, particularly among adolescents, has become a significant public health concern. Main contribution factors are the excessive consumption of fast food, which is often high in calories, fats, sodium, and sugar. This shift in dietary habits is largely leveraged by globalization, which promotes a more convenient yet unhealthy lifestyle. In response to this issue, this study focuses on the designation of fast-food consumption based on nutrition facts, specifically employing data from McDonald’s menu items. The primary goal is to identify consumption patterns and predict whether a particular is at liability of dynamic obesity. This research utilizes the Gaussian Naïve Bayes (GNB) classification algorithm, implemented using the Python programming language. The dataset consists of 500 entries containing nutritional information such as calories, cholesterol, sodium, carbohydrates, sugars, protein, vitamins, calcium, fat, iron, fiber, potassium, minerals, and condition labels indicating obesity risk. The data was carved into training and testing sets, with 20% (100 data points) allocated for testing to assess the conduct of the model. The results of the experiment show that the GNB algorithm achieved an accuracy of 61%. For comparison, other machine learning models were also tested: Random Forest (RF) reach out the accuracy at 68%, succeeded by Multinomial Naïve Bayes at 65%, Support Vector Machine (SVM) and Decision Tree (DT) both at 62%. GNB showed limitations in predicting the TRUE class (indicating obesity risk), with a precision score of 60% and recall of 61%. These results suggest that the dataset distribution and the learning characteristics of GNB contributed to its relatively lower performance. Among the tested models, Random Forest demonstrated the best predictive capability, achieving a TRUE class precision of 76%, significantly outperforming GNB. This indicates that Random Forest is more reliable for classifying obesity risk ba…

ANALISIS METODE MULTI-CRITERIA DECISION MAKING (MCDM) UNTUK PENILAIAN KERUSAKAN DAN KEBUTUHAN PEMULIHAN PASCABENCANA
type: item
description: Indonesia menghadapi risiko tinggi terhadap bencana alam, sehingga penetapan prioritas untuk rehabilitasi dan rekonstruksi pascabencana menjadi hal yang sangat penting. Studi ini mengevaluasi empat metode Multi-Criteria Decision Making (MCDM), yakni ELECTRE, ARAS, SMART, dan CoCoSo, dalam menentukan prioritas penanggulangan bencana berdasarkan data dari Penilaian Kerusakan dan Kerugian (DaLA) serta Penilaian Kebutuhan Pemulihan Manusia (HRNA). Data ini diolah menjadi matriks keputusan dengan enam kriteria utama, menghasilkan peringkat wilayah terdampak untuk masing-masing metode. Validasi melalui korelasi peringkat Spearman telah menghasilkan nilai korelasi sebesar 0,9636 untuk metode penelitian ELECTRE, ARAS, dan SMART, sedangkan metode CoCoSo memiliki korelasi sedikit lebih rendah, yakni 0,9364. Perbedaan ini disebabkan oleh pendekatan algoritma CoCoSo yang menggunakan multi-agregasi, yaitu kombinasi model penjumlahan bobot (WSM) dan perkalian bobot (WPM), yang memengaruhi hasil peringkat. Penelitian ini menyimpulkan bahwa keempat metode layak digunakan dalam pengambilan keputusan pascabencana, meskipun metode berbasis fungsi nilai optimal seperti ARAS cenderung menunjukkan korelasi lebih tinggi. Penelitian juga mendorong pengembangan sistem berbasis teknologi untuk mempercepat dan meningkatkan akurasi proses pengambilan keputusan dalam situasi pascabencana.

PERFORMANCE EVALUATION OF LIGHTWEIGHT OBJECT DETECTION MODELS FOR REAL-TIME PERSONAL PROTECTIVE EQUIPMENT DETECTION IN THE CONSTRUCTION SITES
type: item
description: The environment of construction industry was known to have a high risk and high number of occupational accidents and injuries. One of the main causes of the occurrences was the construction workers' negligence in wearing personal protection equipment. Computer vision-based approaches were developed to assist in personal protective equipment adherence to address this issue. Using lightweight machine learning algorithms, object recognition can help to detect if the PPEs are worn correctly. We evaluated performance of YOLOv8-Nano and YOLOv9-Tiny (state of the art lightweight object detection models). Custom dataset was used for training the models and then metrics like F1 score, precision, recall mAP50 and mAP50-95 were used to evaluate both models’ performance. Results found that both models were able to show promising real time detections, but the YOLOv9-Tiny model was able to outperform the YOLOv8-Nano model on many evaluation metrics. Specifically, in terms of mAP, YOLOv8-Nano achieved an mAP50 of 81.48, while YOLOv9-Tiny attained a slightly higher mAP50 of 82.70. Higher efficiency in these parameters will help small industry to enforce PPE adherence monitoring using edge device at a relatively low cost. Lastly, enhanced enforcement of PPE regulations through automated detection system can contribute to improve workplace safety which in turns will lead to less injuries.

PRESERVING THE INDIGENOUS MUSICAL INSTRUMENTS OF PAPUAN USING AUGMENTED REALITY TECHNOLOGY
type: item
description: This study explores the use of augmented reality (AR) technology as a technology enabling the preservation of traditional Papua musical instruments. It aims of understanding factors that influence the adoption of this technology by people living in Papua who are not indigenous Papuans. The use of AR as a tool for cultural preservation is still limited, particularly in the context of Papua, highlighting a research gap concerning the acceptance of AR technology in regions rich in culture but limited in technology adoption. The study employs Design Science Research (DSR) as a research framework. The development and evaluation in the DSR are conducted rigorously and robustly. Once the AR artifact is developed using uniteAR tool, subsequently it is evaluated employing UTAU2 as a theoretical lens. Particularly in the evaluation stage, it involves 115 respondents as participants in data collection. The data is analyzed with partial least square structural equation modeling (PLS-SEM). The main findings indicate that the measurement model has good reliability and validity, with an R² value of 0.8, meaning that Behavioral Intention and Use Behavior explain 80% of the variability in AR technology adoption. The findings also reveal that performance expectancy, effort expectancy, and facilitating conditions are significant factors driving AR technology adoption among respondents. The implications of this study are highly relevant for the development of strategies using AR technology to introduce and preserve traditional Papua musical instruments. These findings can be used by local governments, indigenous communities, and local content developers to design more effective solutions for enhancing AR adoption in Papua, taking into account key factors influencing public behavioral intentions. Thus, this research not only provides theoretical insights into technology adoption but also strengthens the integration of culture and technology in Papua, opening opportunities for more inter…
