Abstract

Karang Taruna, a youth organization at the village level, manages various assets and equipment to support its activities. However, inventory management has mostly been done manually, making it prone to data entry errors, loss of records, and difficulty in asset tracking. This project aims to design and implement a web-based Inventory Information System tailored to the needs of Karang Taruna. The implementation method includes initial observation of the current inventory process, system design using the waterfall method (analysis, design, implementation, testing), and training for Karang Taruna members. The system was developed using PHP programming language and MySQL database with core features including asset entry and withdrawal recording, asset tracking, report generation, and user and category management. The implementation results show that the system improves the accuracy and efficiency of inventory management. Karang Taruna members also showed enthusiasm in operating the system and understanding the importance of asset management digitalization. This information system marks a significant step in the digital transformation of youth organizations in rural areas and can be replicated in similar organizations elsewhere. recommended.

Abstract

This study aims to group family planning (KB) participants in Ciherang Village based on pregnancy risk levels using the K-Means clustering algorithm. The identification of pregnancy risk is still performed manually, resulting in less effective analysis. Therefore, a data mining approach is applied to improve decision-making accuracy. The data used in this study were obtained from KB cadres, including variables such as age, number of children, education, occupation, and contraceptive methods. The research method follows the Knowledge Discovery in Database (KDD) stages: data selection, preprocessing, transformation, data mining, and evaluation. The K-Means algorithm is used for clustering, while the Davies–Bouldin Index (DBI) is applied to evaluate clustering quality. The results show that the optimal number of clusters is K = 2 with a DBI value of 0.721. The first cluster represents low pregnancy risk participants, while the second cluster represents high pregnancy risk participants. Age and number of children are identified as the most influential factors. This study provides useful insights for healthcare providers in developing targeted strategies for family planning programs.

Abstract

Penelitian ini mengevaluasi pengaruh kualitas data terhadap performa model machine learning menggunakan pendekatan Data-Centric Artificial Intelligence (DCAI). Eksperimen dilakukan pada Titanic Dataset dengan membandingkan Random Forest dan Support Vector Machine (SVM) dalam tiga skenario penanganan missing values, yaitu Drop Missing, Mean Imputation, dan No Imputation. Kinerja model dievaluasi menggunakan metrik Accuracy, F1 Score, dan Area Under Curve (AUC). Hasil menunjukkan bahwa intervensi kualitas data memberikan dampak signifikan terhadap performa model. Random Forest mencapai performa terbaik pada skenario Drop Missing dengan Accuracy 0.813, F1-Score 0.758, dan AUC 0.859, sedangkan SVM memperoleh Accuracy tertinggi sebesar 0.822 pada skenario Mean Imputation. Uji statistik Paired t-Test menunjukkan tidak terdapat perbedaan performa yang signifikan secara statistik antara kedua model (p-value > 0.05). Temuan ini menegaskan bahwa peningkatan kualitas data lebih berpengaruh terhadap kinerja model dibandingkan pemilihan algoritma, sehingga mendukung paradigma Data-Centric AI.

Abstract

Hotspot adalah jaringan nirkabel yang menyediakan akses internet kepada pengguna melalui perangkat Wi-Fi. Kualitas jaringan hotspot sangat penting dalam mendukung berbagai aktivitas, termasuk kegiatan belajar mengajar. Untuk menilai performa jaringan, metode Quality of Service (QoS) digunakan sebagai pendekatan standar dalam mengukur parameter-parameter utama jaringan, seperti throughput, packet loss, delay, dan jitter. Penelitian ini bertujuan untuk menganalisis kualitas jaringan hotspot di SMK Negeri 1 Gebang menggunakan metode QoS. Hasil penelitian menunjukkan bahwa nilai throughput berada dalam kategori "Buruk" hingga "Sangat Buruk" pada jam-jam trafik tinggi (12:00-15:00), dengan nilai berkisar antara 150-318 kbps, sehingga memerlukan optimasi jaringan. Di sisi lain, parameter packet loss tercatat 0%, yang menempatkannya dalam kategori "Sangat Baik." Nilai delay berkisar antara 10,12 ms hingga 30,01 ms, menunjukkan responsivitas jaringan yang baik dalam kategori "Sangat Baik." Sementara itu, nilai jitter berada dalam kategori "Baik" meskipun mengalami sedikit fluktuasi pada jam sibuk. Secara keseluruhan, meskipun performa jaringan dinilai baik dalam aspek packet loss, delay, dan jitter, peningkatan kualitas throughput sangat diperlukan untuk memastikan koneksi yang stabil dan berkualitas, khususnya pada jam trafik tinggi. Temuan ini memberikan dasar untuk pengembangan strategi optimasi jaringan guna mendukung kegiatan pendidikan secara lebih efektif.

Abstract

This study compares the performance of two deep learning architectures—Multilayer Perceptron (MLP) and Long Short-Term Memory (LSTM)—for daily demand forecasting on an e-commerce delivery platform. The dataset consists of 1,827 daily observations from 2020 to 2024 and includes operational, temporal, and behavioral features such as holiday indicators, promotion signals, active customers, and delivery time. Data preprocessing includes cleaning, feature engineering, scaling, and sequence generation using a 30-day sliding window. Both models were trained and evaluated using consistent experimental settings and performance metrics. The results show that the LSTM model achieves better accuracy than the MLP model, with an RMSE of 811.81 compared to 830.15, while the difference in MAE between the two models remains minimal. LSTM demonstrates superior capability in capturing temporal dependencies and reacting to rapid demand fluctuations, whereas both models face challenges when predicting sudden demand spikes. These findings indicate that memory-based models such as LSTM are more effective for highly volatile time-series forecasting in e-commerce operations. However, performance can be further improved with the addition of external variables such as real-time promotions, weather conditions, and multivariate features.

Abstract

This study developed a model for predicting student academic achievement based on learning habits using the XGBoost algorithm and SHAP interpretability techniques. The secondary dataset contains 1,000 entries and 16 variables (for example, hours of study per day, mental health, frequency of exercise, social media use, hours of sleep) pre-processed including cleaning, imputation, encoding, and normalization before being divided into train–test (80:20) and validated using 5-fold CV. Three models were tested: Linear Regression, Random Forest, and XGBoost. Evaluation using RMSE, MAE, and R² showed that XGBoost achieved RMSE = 0.335, MAE = 0.266, and R² = 0.882, while Linear Regression showed the best performance according to R² in certain configurations (R² = 0.888; RMSE = 0.326). SHAP analysis revealed that the most influential features were hours of study per day, mental health scores, exercise frequency, duration of social media use, and hours spent watching Netflix. The findings confirm that students' study habits and psychological conditions are the main determinants of academic achievement variation; the use of interpretable features strengthens the readability of the model for education stakeholders. Research recommendations include testing the model on longitudinal datasets, integrating socioeconomic factors, and implementing data privacy procedures before institutional-scale implementation.
