Abstract

Penentuan kematangan buah kelapa sawit sangat penting untuk meningkatkan kualitas dan kuantitas produksi minyak kelapa sawit. Penelitian ini mengkaji penggunaan teknologi deep learning untuk mengklasifikasikan kematangan kelapa sawit melalui Systematic Literature Review (SLR). Metode penelitian yang digunakan adalah Systematic Literature Review (SLR) yang melibatkan analisis 35 jurnal dari Scopus dan Google Scholar dari tahun 2020 hingga 2024, dengan fokus pada kumpulan data, algoritma, lokasi kumpulan data, dan metode pengukuran kinerja model. Hasilnya menunjukkan bahwa ANN dan CNN adalah algoritma yang paling banyak digunakan, dengan penggunaan masing-masing 16% dan 10%. Akurasi, presisi, perolehan, dan skor F1 adalah metrik kinerja yang paling umum. Penelitian di masa depan harus fokus pada peningkatan generalisasi model dan mengintegrasikan data dari berbagai sumber untuk meningkatkan akurasi klasifikasi, tujuannya untuk berkontribusi pada klasifikasi kematangan minyak sawit dan membantu industri meningkatkan efisiensi dan kualitas produksi.

Abstract

Flooding is one of the most frequent natural disasters in Indonesia, causing significant material losses and casualties. This study aims to develop a flood potential prediction model based on weather data using machine learning approaches, namely XGBoost and Logistic Regression. The dataset consists of 1,513,505 weather records with 1,165 flood events (0.077%). The features include temperature, humidity, wind speed and direction, weather codes, and temporal features generated using a sliding window approach for H-1, H-2, and H-3. Data imbalance was addressed using a combination of stratified undersampling and SMOTE, changing the class ratio from 1:1,298 to 1:3.3. Experimental results show that XGBoost outperforms Logistic Regression, achieving an accuracy of 98.40%, precision of 97.93%, recall of 95.07%, and an ROC-AUC of 99.38%, while Logistic Regression achieved an accuracy of 62.77%. Feature importance analysis indicates that weather codes at H-3 and H-1 are the most influential predictors. With a low false negative rate of 4.9%, the proposed XGBoost model is considered reliable for implementation as a flood early warning system.

Abstract

Path planning is a fundamental problem in mobile robot navigation that requires efficient route optimization while avoiding obstacles. This study implements the Ant System method to solve the mobile robot path planning problem using a modeling and simulation approach in a structured environment. The path planning process utilizes pheromone mechanisms and heuristic information to determine an optimal path from the initial state to the goal state. A total of ten simulation experiments were conducted with variations in the number of intermediate coordinates, iterations, and ants. The results show that the proposed method successfully generated collision-free paths in all experiments, with path lengths ranging from 31.4915 to 32.6788 units. The analysis indicates that the balance between the number of intermediate coordinates, iterations, and ants significantly affects path quality, where well-balanced parameters produce smoother and more stable trajectories. Overall, the Ant System method achieved a 100% success rate, demonstrating its effectiveness and reliability for mobile robot path planning in structured environments.

Abstract

The rapid development of information technology has encouraged the use of data mining as a foundation for data-driven decision-making across various sectors, including the karaoke entertainment industry. This study aims to evaluate the performance of the ID3 algorithm in supporting decision support systems through the construction of a decision tree–based classification model. The research method employs the Knowledge Discovery in Databases (KDD) approach, which involves data selection, data transformation, modeling using the ID3 algorithm, and evaluation of decision outcomes. The performance of the method was evaluated based on five key aspects: decision-making capability, classification processing speed, classification result stability, model interpretability, and suitability to user needs. The results indicate that the ID3 algorithm achieved an average success rate of 92%, with the highest performance observed in processing speed and classification stability. These findings demonstrate that the ID3 algorithm is effective, efficient, and highly interpretable, making it suitable for implementation as a classification method in data mining–based decision support systems.
