Abstract

Road damage, particularly potholes, in Genuk District, Semarang City, is dynamic due to tidal flooding and heavy logistics vehicle loads. Conventional monitoring based on manual surveys and citizen reports is relatively slow and may delay repair responses. This study develops a real-time pothole detection and mapping system by integrating the YOLOv11 algorithm with a Web-GIS interface. The system uses a distributed architecture in which a Python-based local inference layer processes video streams and synchronizes detected potholes with GPS coordinates. Image evidence is uploaded to Cloudinary, while spatial coordinates are stored in a PostGIS-configured PostgreSQL database. The resulting spatial data are visualized through an interactive map developed using TypeScript and Leaflet.js on Vercel serverless infrastructure. The YOLOv11 model was trained for 300 epochs using an NVIDIA Tesla T4 GPU. Evaluation achieved 97.4% precision, 90.4% recall, and 95.1% mAP@50, with an inference latency of 9.3 milliseconds per frame, equivalent to approximately 107 FPS. Functional testing confirmed reliable data transmission and automatic deduplication using the ST_DWithin spatial query. The system provides accurate, responsive, and reliable support for mapping potholes and accelerating road infrastructure repair processes.

Abstract

Penentuan keputusan investasi saham merupakan proses yang kompleks karena dipengaruhi oleh berbagai faktor seperti pergerakan harga historis, kondisi fundamental perusahaan, serta dinamika pasar yang bersifat non-linear. Investor sering mengalami kesulitan dalam mengintegrasikan berbagai informasi tersebut secara sistematis. Penelitian ini bertujuan untuk mengembangkan sistem rekomendasi saham berbasis probabilistik menggunakan pendekatan hybrid antara model Autoregressive Integrated Moving Average (ARIMA) dan Random Forest. Model ARIMA digunakan untuk menghasilkan prediksi harga saham pada horizon 7 hari, sedangkan Random Forest digunakan untuk mengklasifikasikan rekomendasi investasi menjadi buy, sell, atau hold berdasarkan fitur teknikal, fundamental, dan output ARIMA. Sistem juga dilengkapi dengan mekanisme keputusan probabilistik melalui penerapan threshold dan filtering untuk meningkatkan kualitas sinyal. Hasil pengujian menunjukkan bahwa model memiliki performa klasifikasi dengan nilai ROC-AUC di atas 0.5 dan akurasi sekitar 52%. Evaluasi menggunakan backtesting pada data out-of-sample menunjukkan bahwa sistem mampu menghasilkan return sebesar ±46.5% dengan win rate 78.6%. Hasil ini menunjukkan bahwa pendekatan yang diusulkan mampu menghasilkan rekomendasi investasi yang selektif dan memiliki performa yang baik dalam simulasi perdagangan.
