Abstract

In the realm of machine learning, classification models are important for identifying patterns and grouping data. Support Vector Machine (SVM) and Robust SVM are two types of models that are often used. SVM works by finding an optimal hyperplane to separate data classes, while Robust SVM is designed to deal with uncertainty and noise in the data, making it more resistant to outliers. However, SVM has limitations in dealing with class imbalance and outliers in the dataset. Class imbalance makes the model tend to predict the majority class, and outliers can interfere with model formation. This research compares the performance of SVM and Robust SVM on normal, unbalanced and outlier datasets. The software uses Python and Scikit-learn for implementation and comparison of the two models. Key features include automatic data preprocessing, model training, and evaluation with metrics such as accuracy, precision, recall, and F1 score. The results show that Robust SVM is superior in accuracy on normal datasets and is very effective in dealing with class imbalance, achieving a maximum accuracy of 100%. On datasets with outliers, Robust SVM maintains stable accuracy, demonstrating its robustness to outliers. This research contributes to correspondence management by providing more reliable classification models, improving data processing accuracy, and supporting more informed decision making in software development

Abstract

SMA Negeri 1 Simpang Empat salah satu sekolah yang bergerak dibidang pendidikan sekolah menengah atas yang beralamat di jalan Benteng No 2 Simpang Empat, Kecamatan Simpang Empat, Kabupaten Asahan, Sumatera Utara. Adapun kegiatan ekstrakurikuler pada SMA Negeri 1 Simpang Empat diantaranya pramuka, osis, rohis, voli dan PMR (Palang Merah Indonesia). Permasalahan di SMA Negeri 1 Simpang Empat saat ini belum tersedia sistem terkomputerisasi yang dapat membantu proses pemilihan ekstrakurikuler bagi siswa sehingga belum ada metode yang dapat digunakan untuk menyesuaikan pilihan ekstrakurikuler dengan minat dan bakat masing-masing siswa. Akibatnya, pemilihan ekstrakurikuler masih dilakukan secara preferensi pribadi atau pengaruh dari temen tanpa acuan yang jelas karena siswa cenderung memilih berdasarkan preferensi pribadi atau sekadar mengikuti pengaruh dari teman sebaya tanpa mempertimbangkan potensi dan bakat yang mereka miliki secara lebih objektif. Hal ini dapat menyebabkan ketidaksesuaian antara ekstrakurikuler yang dipilih dengan kemampuan atau ketertarikan siswa sehingga efektivitas kegiatan ekstrakurikuler dalam mengembangkan potensi mereka menjadi kurang optimal. Untuk mengatasi permasalahan ini, diperlukan sebuah sistem rekomendasi yang dapat digunakan adalah Simple Additive Weighting (SAW), yang memungkinkan proses seleksi dilakukan secara objektif. Metode SAW sering disebut sebagai metode penjumlahan berbobot. Tujuan penelitian ini adalah untuk mengembangkan sistem rekomendasi ekstrakurikuler yang dapat membantu siswa memilih program ekstrakurikuler berdasarkan minat dan bakat. Metode penelitian yang digunakan dalam penelitian ini yaitu metode penelitian kuantitatif. Sistem berbasis data dapat menggantikan proses manual dalam pemilihan ekstrakurikuler dengan cara yang lebih efisien dan memberikan hasil yang lebih objektif sehingga mempermudah siswa dalam menentukan pilihan ekstrakurikuler yang sesuai

Abstract

The development of information technology encourages small businesses to adopt digital systems to improve operational efficiency and data management. However, many small-scale garment businesses still rely on manual inventory management processes, which often result in data inconsistencies, delays in reporting, and inefficient coordination. This study aims to develop a web-based Electronic Supply Chain Management (E-SCM) system to improve inventory control and operational performance. The research applies the Software Development Life Cycle (SDLC) using the Waterfall model, which includes requirement analysis, system design, implementation, testing, and evaluation. Data collection was conducted through observation and interviews, while system testing was performed using the Black Box Testing method. The results show that the implementation of the system significantly improves operational efficiency. The time required to generate inventory reports decreased from approximately 60 minutes to 10 minutes (an improvement of 83%), while stock data accuracy increased from 85% to 95%. In addition, stock discrepancies were reduced from 15% to 5%, indicating better data consistency and control. This study contributes by providing an integrated E-SCM model combined with measurable performance indicators for small-scale garment businesses. The findings imply that the adoption of the proposed system can enhance efficiency, accuracy, and decision-making in inventory management.   Keywords: E-SCM, Inventory System, SDLC, Web-Based System, Supply Chain Management.

Abstract

Feed management is an important factor in supporting successful production in chicken farming businesses. At the Giran White Chicken Farm, the feed stock recording process is still done manually, which often results in inaccurate records, delays in feed orders, and difficulties in preparing operational reports. This study aims to design and implement a web-based Supply Chain Management (SCM) system to improve the effectiveness of feed management. The research methods include observation, interviews, and documentation, while the system design uses Unified Modeling Language (UML) with application development using PHP and MySQL. The built system is tested using the black-box testing method to ensure that all system functions run according to user requirements. The results show that the implementation of the system has increased stock recording accuracy from 78% to 96%, reduced stock discrepancies from around 15% to 4%, and accelerated the report generation process from around 2 hours to ±10 minutes. With the web-based SCM system, the feed management process has become more structured, integrated, and supports faster and more accurate operational decision-making at the Giran White Chicken Farm.

Abstract

The problems that are often faced at aesthetic clinics are managing drug data and checking the availability of the drug stock itself, which is still less effective and product sales transactions differ between transaction notes received by customers and goods coming out of the warehouse. Because in one day if several patients buy drugs in sufficient quantities, thus the stock in the warehouse will also be running low. Often there is a shortage of medicine stock because they don't check and count every medicine in the warehouse.
