Abstract

Banyaknya spesies burung membuat kita kesulitan untuk mengenali jenis burung dan diperlukannya pemahaman yang lebih khususnya dalam bidang zoologi. mengenali spesies burung secara manual merupakan tugas berat, di perlukannya SDM yang besar untuk mengidentitifikasi spesies burung apalagi jumlah yang akan akan di identifikasi begitu banyak dan juga memakan banyak waktu. Pada penelitian ini membuat sebuah sistem yang dapat mengenali spesies burung menggunakan citra gambar secara otomatis dengan menggunakan salah satu Arsitektur dari Convolutional Neural Network yaitu Inception Resnet V2, sehingga data citra tersebut dapat diekstraksi kemudian dapat mengenali spesies dari jenis burung. Yang bertujuan untuk melakukan pemantauan satwa khususnya burung dengan mengidentifikasi spesies burung secara otomatis, kemudian diharapkan masyarakat dengan mudah untuk mengenali jenis burung dan juga meningkatkan kemampuan kita untuk mempelajari dan melestarikan ekosistem khususnya ekosistem burung.

Abstract

This research examines how to recognize objects in digital images with results that can be explained logically like the perspective of the human eye. Pattern recognition techniques using statistical methods cannot provide a logical description of the recognized objects, because this concept considers the features used as probability classes, so the essence of the way the human eye sees cannot be demonstrated. The syntactic method is also not able to provide a logical description of the object that is recognized according to the perspective of the human eye, this concept prioritizes low-level features for the recognition process. So, in this research, we examine several syntactic and statistical recognition methods that adapt some of the standard abilities of the human eye. Features such as lines, chain codes, and colors have been able to define objects in images, and approach human reasoning. Simple Human Eye Movement Analysis, can help us to detect the relationship between line, true color, and chain code to show the object unity. We hope that developing this approach will enrich the object pattern recognition method to be simpler and faster.

Abstract

Stress is often the main challenge faced by students due to academic and social demands in the educational environment. Factors such as nervousness, inability to control oneself, worry, etc. are several stress triggers, all of which can have a negative impact on students' physical and mental health. This research aims to identify the level of stress experienced by students using the K-Nearest Neighbors (KNN) method and evaluate the accuracy of the results of this research. The KNN method is used to classify student stress levels based on similarity or closeness to other data in the dataset. By using data taken from the data.world site, the results of this research show that the KNN method is able to achieve an accuracy of 91.58%. In addition, the precision, recall, and f1-score values are 76.10%, 73.11%, and 74.17% respectively. This research makes an important contribution in understanding student stress levels and shows the effectiveness of the KNN method in classifying stress data. It is hoped that these results will help in the development of better strategies for managing and reducing stress among college students.

Abstract

In today's digital era, recommendation systems have become an integral part of supporting consumer purchasing decisions, including in the food and beverage industry. This study aims to develop a product recommendation system for snacks and beverages using the item-based collaborative filtering method. This method was chosen due to its ability to handle large-scale user and product data, as well as its efficiency in providing relevant recommendations based on user consumption patterns. In this study, the system calculates the average user rating and implements   Cosine Similarity to measure the similarity between products, resulting in more accurate recommendations. The system also evaluates the accuracy of recommendations using the Mean Absolute Error (MAE) metric. Based on the results obtained, which is 0.285403 for the average error on 17 items, the developed recommendation system can improve consumers' shopping experience, help them find products that suit their tastes, and support the sales of snacks and beverages products in the market

Abstract

Essay assessment remains a persistent challenge in many schools due to the time-consuming nature of manual grading and the variability that arises from assessor subjectivity. This situation highlights the need for an automated scoring system capable of producing fast, consistent, and teacher-comparable evaluations. This study proposes a hybrid approach for automatic essay scoring by combining semantic similarity from Sentence-BERT with lexical features derived from Jaccard Similarity, Levenshtein Similarity, Keyword Coverage, and Length Penalty. The five similarity components are integrated using a weighted aggregation scheme and calibrated to the 0–100 scoring scale through linear regression. The model was tested on a dataset of high-school essay responses accompanied by manual teacher scores. Experimental results indicate that the proposed system performs reliably, achieving a Mean Absolute Error (MAE) of 3.58 and a Root Mean Square Error (RMSE) of 4.48 on the test set. The model also demonstrates strong practical alignment with teacher scoring, reaching an agreement rate of 87.30% within a tolerance of ±7 points. These findings suggest that the hybrid method can approximate human scoring patterns with a high degree of consistency, providing a promising tool to support objective and efficient assessment processes in educational settings.

Abstract

Perlindungan data medis menjadi prioritas utama di era digital karena tingginya risiko kebocoran dan penyalahgunaan informasi pasien. Regulasi seperti HIPAA, GDPR, dan Undang-Undang Kesehatan No. 36 Tahun 2009 mewajibkan penerapan keamanan, namun tantangan teknis dalam implementasi masih besar. Differential Privacy (DP) menawarkan pendekatan matematis untuk menjamin privasi dengan menambahkan noise terkontrol sehingga keberadaan individu sulit diidentifikasi tanpa mengurangi nilai analisis data. Penelitian ini bertujuan mengevaluasi efektivitas DP pada dataset prescriptions. Data yang diuji bersumber dari database rekam medis publik MIMIC-III yang mencakup ribuan catatan resep. Empat atribut sensitif (row_id, subject_id, hadm_id, icustay_id) dianalisis menggunakan variasi parameter ε = {0.1, 0.5, 1.0, 5.0}. Evaluasi dilakukan menggunakan Mean Squared Error (MSE) dan Root Mean Squared Error (RMSE) untuk menilai trade-off antara privasi dan akurasi. Hasil penelitian menunjukkan bahwa Laplace mechanism lebih stabil dibanding Gaussian dengan nilai RMSE konsisten lebih rendah, terutama pada ε kecil hingga sedang. Gaussian menghasilkan error tinggi pada ε kecil dan baru mendekati Laplace pada ε besar. Kebaruan penelitian ini terletak pada analisis kuantitatif langsung menggunakan RMSE untuk membandingkan kinerja mekanisme Laplace dan Gaussian pada atribut-atribut identitas rekam medis, memberikan bukti empiris praktis yang melengkapi studi sebelumnya yang seringkali bersifat teoretis atau tinjauan umum. Temuan ini menegaskan bahwa pemilihan mekanisme dan parameter ε sangat menentukan kualitas data medis yang diproteksi. Secara praktis, penelitian ini merekomendasikan penggunaan Laplace mechanism dengan ε = 0.5–1.0 untuk implementasi Differential Privacy pada sistem rekam medis elektronik. Konfigurasi
