Abstract

The Pamurbaya mangrove conservation area in East Surabaya is crucial for coastal protection, but it is vulnerable to degradation due to human activities and land-use changes. Species distribution maps are essential for understanding ecological functions, such as carbon sequestration, salinity tolerance, and ecosystem stability. This study utilizes multiresolution remote sensing data from WorldView-2 satellite imagery to map mangrove and detailed species-level. Random Forest is utilized to differentiate mangrove and non-mangrove, while Linear Spectral Unmixing allows for detailed mangrove species distribution. Further analysis was carried out to determine at what resolution the LSU works optimally. The imagery was served in 0.5 meter resolution and down-sampled to 5 meter, 10, 20, 30, and 50 meter resolutions. This study obtained that LSU were able to differentiate mangroves according to its endmember and working optimally at medium resolution (10–30 m), with overall accuracy increasing from 70% (10 m) to 75% (30 m) and Kappa value increasing from 53.7 to 60.41. High resolution (0.5–10 m) provides more detailed mapping but is optimal for species with small and scattered distributions. Meanwhile, low resolution (20–50 m) tends to cause overestimation or aggregation of species.

Abstract

The Urban Heat Island (UHI) phenomenon in Surabaya is becoming increasingly apparent due to the conversion of green areas into built-up areas. This community service activity aims to map land surface temperature (LST) for the period 2016–2024 using Landsat 8 level 2 imagery and present it in augmented reality (AR) visualization to support public literacy. The analysis was conducted through calculations of NDVI, emissivity, LST, NDVI–LST linear regression, and field validation usinga thermohydrometer. The results show that the distribution of LST increased in 2016–2019, decreased in 2020, then increased again in 2021–2023 before decreasing in 2024. The negative correlation between NDVI and LST indicates that vegetation plays an important role in reducing temperatures. Field validation produced a coefficient of determination (R²) of 0.7213 with a maximum difference of 5°C between satellite data and measurements. The 2024 UHI map shows high intensity in densely built-up areas (Tegalsari, Genteng, Sawahan, Tambaksari, Wonokromo, and parts of Rungkut), while outlying areas like Benowo and Pakal are relatively cooler. AR-based visualizations have proven effective in helping the public and policymakers understand the UHI phenomenon more interactively and encouraging the development of mitigation strategies through reforestation and sustainable urban planning.
