Abstract

UMPAR at the age of 18 has walked through two phases, namely; the pilot phase, and the development phase.. The high school, namely STKIP Muhammadiyah Parepare at that time, fostered three study programs, namely the Mathematics Education, English Education and Non-Formal Education (PLS) study programs. The effort to transform into a university was initiated by Drs. Said Amir Anjala, M as well as the First Rector. Unity supports all file formats, especially common formats such as all formats from artapplications. Unity is compatible with 64 bit versions, can operate on Mac Os x, Windows and Can produce games for mac, windows, Wii, iphone, ipad and Android. The research method used is Literature Study and Observational Research. In making this application using the C # programming language. The need for making a virtual tour application in taking pictures using the google camera application. This research produces games that can be played offline on all computers with low specifications and also on Android smartphones.

Abstract

Reliable, explainable crop-yield estimates are essential for food-security planning in data-sparse regions. We present a transparent pipeline for district-level (regency) rice yield prediction in Indonesia that fuses Sentinel-1 synthetic aperture radar (SAR), Sentinel-2 normalized difference vegetation index (NDVI), and weather/reanalysis features. The system standardizes inputs per province, fixes a 16-day temporal key, and uses a small, auditable ensemble of tree models (gradient boosting+light gradient-boosting machine (LightGBM)). Trained on ≤2023 data and evaluated on a 2024 temporal hold-out, a joint West Java ∪ South Sulawesi model achieves root mean square error (RMSE)≈0.80 t/ha, mean absolute error (MAE)≈0.48 t/ha, and R-squared (R²)≈0.33 at regency scale. Feature importances and Shapley additive explanations (SHAP) confirm that phenology (NDVI peak, integral, green-up/senescence), SAR backscatter (vertical transmit-vertical receive/vertical transmit-horizontal receive (VV/VH)), and wind/pressure are consistent drivers under monsoon conditions. The workflow supports routine, one-click provincial updates and produces parity maps and error bars for actionable diagnostics. These results demonstrate that combining Sentinel-1, Sentinel-2, and basic meteorology delivers accurate, interpretable, and operational yield signals suited to Indonesia’s food security needs, while providing a clear recipe for scaling to additional provinces.
