Indonesian Sign Language (BISINDO) is the primary communication medium for the deaf community, yet limited public understanding often leads to communication barriers. Previous sign language recognition studies have generally been conducted offline, lacked real-time web integration, and produced only text-based outputs without multimodal interaction. To address these limitations, this study proposes a real-time web-based BISINDO translator system using a hybrid Convolutional Neural Network (CNN) and Long Short-Term Memory (LSTM) model, integrated with a Text-to-Speech (TTS) feature. The novelty of this research lies in the combination of CNN for spatial feature extraction and LSTM for temporal sequence learning within a fully deployed web application framework (NzSignify), enabling real-time end-to-end sign language translation with both text and voice output. The dataset consists of primary video recordings from three subjects, covering 11 gesture classes with 1,000 grayscale frames per class at a resolution of 100×89 pixels. The proposed model is implemented using a React.js and Node.js-based system to support real-time inference. Experimental results show that the hybrid CNN-LSTM model achieves a classification accuracy of 96% based on Confusion Matrix evaluation. In real-time testing, an 80% confidence threshold effectively filters misclassified gestures and improves translation reliability into text and speech outputs. Compared to previous studies that mainly rely on standalone CNN or traditional machine learning methods with offline processing, the proposed approach demonstrates improved capability in capturing both spatial and temporal features of sign gestures as well as supporting real-time deployment. These findings indicate that the developed system provides a more practical, accurate, and interactive solution for BISINDO translation, enhancing communication accessibility between deaf and hearing communities through a real-time multimodal platform.

Ridho Pratama, Mahardika Abdi Prawira Tanjung — Thu, 30 Apr 2026 00:00:00 +0000

Landslides are natural disasters that can cause casualties, environmental damage, and infrastructure losses. One challenge in landslide mitigation is the limited availability of monitoring systems that can provide fast, real-time, and interpretable information about ground conditions. This study aims to design and develop an Internet of Things (IoT)-based ground vibration monitoring system with landslide potential classification using Support Vector Machine (SVM). The system uses an MPU6050 sensor to acquire ground vibration data and an ESP8266 microcontroller to transmit data through a Wi-Fi network to a server. The collected data are processed through preprocessing, windowing, feature extraction, and standardization before being classified into three condition categories: Safe, Alert, and Danger. The classification results are displayed on an LCD, visualized through a web dashboard, and used to activate a relay as a warning mechanism when a dangerous condition is detected. The testing results show reliable data transmission with a 100% delivery success rate in the observed test and an average latency of approximately 0.3 seconds. The SVM model achieved 99.79% accuracy, with high precision, recall, and F1-score for all classes. Therefore, the proposed prototype can support ground vibration monitoring and early landslide warning efforts more effectively.

Muhammad Naufal Dzakiyya, Zuli Agustina Gultom — Thu, 30 Apr 2026 00:00:00 +0000

Livestock farming serves as a vital economic pillar for the community in Bandar District, Simalungun Regency. However, the high intensity of livestock activities is accompanied by a significant risk of disease transmission, which has historically been managed through conventional recording methods that lack spatial integration. This research aims to analyze the spatial distribution patterns of livestock diseases by implementing the Density-Based Spatial Clustering of Applications with Noise (DBSCAN) method integrated into a web-based Geographic Information System (GIS). Using a quantitative approach, the study processed 200 case records from December 2025 to January 2026. Spatial distances were calculated using the Haversine formula to ensure geographic accuracy. The results indicate that the optimal parameters for the DBSCAN algorithm are an epsilon ($\epsilon$) of 3.0 km and a minimum points (MinPts) of 2. These parameters successfully identified two primary clusters with zero noise, encompassing all 200 cases. Cluster 1 (98 cases) is concentrated in the west-central region, dominated by cattle and goats with diverse pathologies such as Scabies and BEF. Cluster 2 (102 cases) is located in the east-northern region and exhibits a more heterogeneous livestock profile, including rabies cases in dogs. High-density areas requiring priority intervention were identified in Pematang Kerasaan Rejo and Perdagangan II. The developed web-based GIS provides an interactive visualization platform that enhances early warning capabilities and supports data-driven decision-making for livestock disease surveillance and regional control.

Thu, 30 Apr 2026 00:00:00 +0000

Monitoring physical condition and training activities is an important aspect in the development of student cadets within the Student Cadet Corps Regiment. However, the monitoring process that is still conducted manually reduces the effectiveness of tracking training compliance and the physical development of cadets. This study aims to design and develop a web-based application system for tracking the training activities and physical conditions of student cadets to support structured recording, monitoring, and evaluation of physical fitness. The system development method used in this research is Rapid Application Development (RAD), which emphasizes rapid prototyping and iterative improvements based on user feedback. The system was developed using the CodeIgniter framework for backend development, Bootstrap for frontend design, and MySQL as the database management system. The application enables cadets to record running activities and physical condition data such as height and weight, which are then calculated using the Body Mass Index (BMI) method. The data are stored in the database and visualized through graphical progress reports to facilitate monitoring of training outcomes. In addition, the system provides an administrative dashboard that allows regiment officials to centrally monitor the physical condition and training compliance of cadets. The results show that the developed system can improve the effectiveness and efficiency of training monitoring compared to the previously used manual method.
