Abstract

Pencatatan insiden sangat penting dalam operasional data center karena menyediakan dokumentasi terpusat untuk setiap kejadian. Saat ini, PT. Infracom Telesarana belum memiliki sistem manajemen insiden yang terintegrasi dan masih bergantung pada vendor eksternal, yang menghambat efisiensi. Penelitian ini bertujuan untuk mengembangkan sistem manajemen insiden dan operasional harian yang terintegrasi secara mandiri guna meningkatkan efektivitas operasional serta mendukung rekonsiliasi data bulanan. Sistem dikembangkan menggunakan bahasa pemrograman PHP dengan framework Laravel dan penyimpanan data menggunakan MySQL. Pengembangan dilakukan dengan metode Prototype dan pemodelan sistem menggunakan Unified Modeling Language (UML). Antarmuka berbasis web diterapkan untuk mempermudah tugas harian dan meningkatkan kemudahan penggunaan. Sistem yang diusulkan dirancang untuk mengatasi tantangan operasional yang ada dan diharapkan dapat meningkatkan efisiensi secara keseluruhan dengan mengurangi ketergantungan pada vendor serta memungkinkan pelacakan insiden yang lebih baik.

Abstract

Penelitian ini bertujuan untuk membuat dan mengevaluasi model prediksi jumlah anak dengan gizi buruk di berbagai daerah di Jawa Barat menggunakan algoritma regresi linier. Data diambil dari Open Data Jabar yang mencakup berbagai faktor risiko. Fokus utama adalah mengukur akurasi dan efektivitas model dalam mendeteksi kasus gizi buruk serta menyelidiki peran teknologi pembelajaran mesin dalam membantu perencanaan dan penerapan intervensi kesehatan. Hasil penelitian menunjukkan bahwa model regresi linier yang dibuat memiliki tingkat akurasi yang memadai dengan R² sebesar 0.64, yang berarti model dapat menjelaskan 73% variasi dalam jumlah anak. Prediksi menunjukkan hasil yang sebanding dengan data asli, terutama di daerah dengan banyak anak. Penggunaan machine learning terbukti membantu pemerintah daerah dan lembaga kesehatan dalam menemukan wilayah yang membutuhkan perhatian khusus dan memungkinkan penempatan sumber daya yang lebih tepat sasaran dan efektif. Prediksi menunjukkan bahwa beberapa daerah, seperti Kabupaten Garut, Kabupaten Cirebon, dan Kabupaten Bogor, mungkin memiliki tingkat kasus gizi buruk yang lebih tinggi, yang memerlukan perhatian lebih dalam program kesehatan.

Abstract

The Al-Muslim Foundation is an organization that carries out the process of selling sacrificial animals, but still uses traditional methods such as recording orders, payments and animal information manually using books or physical records. This has the potential to cause recording errors and data loss, which makes it very possible for errors to occur in the process. This research aims to build a web-based system to help handle this problem. The system that will be created uses the Rapid Application Development method. Testing of this system will be carried out using the black box testing method. The results of this research show that the Al-Muslim Foundation has succeeded in increasing effectiveness and efficiency in the process of selling sacrificial animals, as well as expanding sales so that they can be accessed by potential buyers anytime and anywhere.

Abstract

Breast cancer detection is an important stage for early cancer diagnosis. In this study, a Convolutional Neural Network (CNN) algorithm is used to detect breast cancer. The dataset used consists of MRI scan images of benign and malignant breast cancer, which are processed through breast image cropping and data augmentation. The model was trained using CNN architecture with transfer learning method of VGG-16 model. The results of the model training showed good performance with an accuracy of 62%. These findings show the potential of using CNN and transfer learning in improving early detection of breast cancer.

Abstract

In an era of increasing concern for environmental sustainability, waste management remains an important global issue. Efficient waste classification, in particular distinguishing between organic and recyclable materials, is essential for reducing environmental impact. Traditional manual classification methods are often error-prone and inefficient. This research evaluates the performance of SVM models with RBF and Polynomial kernels for waste classification, using SqueezeNet for feature extraction. Datasets from Kaggle were preprocessed and augmented to improve model training. The experimental results show that the SVM model with RBF kernel outperforms the Polynomial kernel in classifying organic and recyclable waste, with an accuracy of 97.9% compared to 97.3% for the Polynomial kernel. This finding underscores the importance of kernel selection and parameter tuning in optimising SVM models for non-linear classification tasks. This research contributes to the development of more efficient and accurate waste classification technologies, promoting better waste management practices. Further research is recommended to explore advanced feature extraction methods and expand the scope of classification to cover a wider range of waste categories.

Abstract

This study presents the development and evaluation of a CNN-based model for detecting safety helmets in industrial settings. Utilizing a dataset from GitHub, which includes images of individuals wearing safety helmets in various industrial environments, the model was trained using the YOLOv8 architecture over 100 epochs. The comprehensive training process involved data augmentation techniques to enhance generalization capabilities. The evaluation results demonstrated high precision (0.92) and recall (0.856) for helmet detection, with an overall mAP50 of 0.766. Visual analysis through precision-confidence curves confirmed the model's high reliability in detecting helmets at higher confidence thresholds. These findings suggest that the implementation of this model in real-time monitoring systems could significantly enhance industrial safety by reducing manual inspection efforts and ensuring compliance with safety regulations

Abstract

This community service program aims to improve the ability of IT Insan Kamil Cikarang Middle School teachers in conducting learning evaluations using the Computer-Based Test (CBT). Teachers will be given training and an introduction to CBT and given practice to create questions and enter them into the CBT platform. The training method used is a competency-based training approach using demonstration methods and hands-on practice in learning. The results of this training indicate an increase in teacher competency in designing, developing, and implementing information technology-based learning evaluations. It is hoped that this program can increase effectiveness and efficiency in learning evaluation, as well as increase student motivation in learning. Challenges that need to be overcome include the lack of understanding and use of technology by teachers and students, and the need for the right approach in implementing CBT. This program is expected to provide greater benefits for teachers and students.

Abstract

This research investigates the effectiveness of two machine learning models (Logistic Regression and Random Forest) in predicting employee turnover. This research uses IBM HR Analytics employee attrition and performance dataset and performance dataset from Kaggle and implements nested ensemble models in Google Colab. After data pre-processing steps such as feature merging, generation, engineering, cleaning, coding, and normalisation, the data is divided into training and testing sets. The models were trained and evaluated based on their accuracy. The results of averaging the three departments showed that the Random Forest model achieved the highest accuracy (97.7%) compared to Logistic Regression (94.6%). Therefore, this study shows that Logistic Regression is the most suitable model to predict employee turnover in the given dataset.

Abstract

This study compares the accuracy of K-Nearest Neighbors (KNN) and Naive Bayes algorithms in detecting defects in impeller products. Using a dataset of impeller images, we applied preprocessing, feature extraction, and selection techniques. The models were assessed using metrics such as precision, accuracy, F1-score, recall. and with KNN achieving 98.11% accuracy and Naive Bayes 85.38%. The t-SNE visualization confirmed distinct clustering of defective and non-defective products. Our findings suggest that KNN is more reliable for defect detection in industrial applications. These results provide valuable insights for implementing effective machine learning models in manufacturing quality control.
