Abstract

Gangguan hama burung pada lahan pertanian, khususnya di area persawahan, menjadi salah satu faktor yang menyebabkan penurunan hasil panen. Penelitian ini bertujuan untuk mengembangkan sebuah alat otomatis berbasis sistem tertanam (embedded system) yang berfungsi sebagai pengusir burung di sawah. Alat ini bekerja dengan menarik tali lonceng secara otomatis, sehingga menghasilkan bunyi yang dapat mengusir burung secara efektif. Sistem ini terdiri dari beberapa komponen utama, yaitu panel surya sebagai sumber energi, motor penggerak, lengan penarik, dan mikrokontroler sebagai pusat kendali. Mikrokontroler diatur untuk menggerakkan lengan penarik dan mengatur waktu operasional secara otomatis. Hasil pengujian menunjukkan bahwa alat ini mampu beroperasi secara stabil dan efektif dalam mengusir burung, serta dapat bekerja secara mandiri dengan memanfaatkan energi terbarukan dari panel surya. Dengan demikian, alat ini diharapkan dapat menjadi solusi praktis dan berkelanjutan dalam mengatasi masalah hama burung di sektor pertanian.

Abstract

Twitter (X) has become an important platform for community interaction, but this also creates serious challenges due to the proliferation of fake accounts that can harm users and undermine credibility. Previous studies have proposed detection methods but often lacked forensic analysis based on extracted feature information. This study utilizes labeled datasets and supervised evaluation metrics (precision, recall, and F1-score) to validate model performance. Extracting behavioral information from features is crucial for achieving accurate and reliable detection results. The study introduces a novelty in the form of engineered behavioral features that significantly enhance detection accuracy, achieving up to 99.94% using AdaBoost. The proposed approach detects fake accounts on Twitter (X) by extracting key feature information and developing an optimal detection method through machine learning algorithms, including Random Forest, SVM, and AdaBoost. Furthermore, the model is optimized using feature engineering techniques. The novelty of this work lies in the development of engineered features through distribution analysis based on data characteristics and the improvement of classification performance through feature engineering optimization. The initial experiment without feature engineering shows that Random Forest achieved the highest accuracy of 98.77%, followed by AdaBoost at 98.57% and SVM at 95.90%. After applying feature engineering, performance improved, with AdaBoost reaching 99.94%, Random Forest 99.69%, and SVM 99.32%. The proposed model can assist system analysts in detecting fake accounts and contribute to solving forensic cybercrime challenges, particularly in identifying fake social media profiles.

Abstract

Fish diseases are a major challenge in the aquaculture industry, impacting productivity and the economy, particularly in salmon farming. This study aims to develop an image classification system for infected salmon using Convolution Neural Network (CNN) deep features approach and Support Vector Machine (SVM) classifier optimized with Optuna. The dataset consists of 1,208 images that were balanced through augmentation before being divided into 70% training data and 30% test data. Features were extracted from the middle layer of three pretrained CNN architectures: EfficientNetB1 (block6d_add), ResNet50 (conv4_block6_out), and VGG16 (block4_pool), then selected using the Least Absolute Shrinkage and Selection Operator (LASSO) method to address high-dimensionality issues. An SVM classification model was trained using stratified 5-fold cross-validation, both with default parameters and hyperparameter optimization results from Optuna. The results show that the model with features from EfficientNetB1 tuned by Optuna achieved the highest accuracy of 99.34%, a significant improvement over the default model 98.23%. Meanwhile, ResNet50 and VGG16 achieved optimal accuracies of 98.23% and 98.89%, respectively, after tuning. This study contributes to the development of an adaptive and accurate early detection system for infected fish.

Abstract

Instagram has become known as one of the leading platforms in digital marketing, making it essential to systematically evaluate the effectiveness of the content presented to ensure successful communication strategies. This study aims to measure the effectiveness of Instagram content produced by Kayana Creative using the EPIC Model and the Direct Rating Method, two complementary evaluative approaches that assess content quality and audience reception. The research involved 100 respondents who follow the Kayana Creative Instagram account. Data collected using a Likert-scale questionnaire and analyzed quantitatively to assess the four EPIC dimensions. Empathy, Persuasion, Impact, and Communication, as well as the overall evaluation through the Direct Rating Method. The results indicate that Instagram content is effective, with an average EPIC score of 4.04. The Communication dimension scored highest, indicating that the audience clearly understood the content’s messages. Using the Direct Rating Method, respondents provided an overall score of 80.48, further confirming that the content effectively captures attention and delivers a positive user experience. This study provides practical contributions for developing content that is more relevant, communicative, and engaging, and theoretical contributions by reinforcing the use of the EPIC Model and the Direct Rating Method as complementary evaluative tools for assessing content effectiveness on social media within the digital marketing context.
