Abstract

Banyubiru Sub-District is the sub-district that experienced the most landslides in Semarang Regency. The condition of steep slopes in several areas in this sub-district is quite dangerous to be used as a residential, industrial and commercial area because of the high probability of disasters, especially landslides. This research focuses on identifying landslide hazard areas, especially on built-up areas in Banyubiru Sub-District, Semarang Regency. The production of landslide hazard map refers to Peraturan Menteri Pekerjaan Umum Nomor 22/PRT/M/2007. The method used to identify landslide hazard areas is scoring and weighting using several parameters, namely slope, land cover, rock type, rainfall and soil type. Based on the processing, it can be known that mapping using the average monthly rainfall parameter for three months is more accurate than using annual rainfall. Landslide hazard on built-up areas in Banyubiru Sub-district is divided into three levels with the dominance of medium landslide hazard level covering 69% or approximately 275.70 Ha. The validation results show that out of 55 landslide events in Banyubiru Sub-district, 17 events occurred on built-up areas with medium to high hazard levels.

Abstract

This study analysed spatiotemporal changes in mangrove canopy density within the coastal areas of Pekalongan Regency and Pekalongan City using multitemporal Sentinel-2 imagery (2019, 2021, and 2024). This study was motivated by the continuous degradation of mangrove ecosystems due to severe tidal flooding, land subsidence, and coastal hydrodynamic disturbances, which necessitate reliable monitoring tools to support mitigation and restoration programs. The objective of this study was to compare the performance of NDVI, NDVI-Red Edge, and mRE-SR vegetation indices in estimating mangrove canopy density and to determine the most accurate index for tidal-affected environments. The methodological framework involved image preprocessing, land cover classification, vegetation index computation, and linear regression modelling validated by in situ canopy measurements obtained through hemispherical photography. The results showed that the mangrove area declined significantly between 2019 and 2021, followed by partial recovery in 2024 in response to rehabilitation efforts. Among the tested indices, NDVI-Red Edge Band 5 yielded the highest accuracy with the lowest RMSE (7.65%), outperforming NDVI and mRE-SR, whereas Bands 6 and 7 showed weak predictive capability. The study concluded that NDVI-RE Band 5 is the most reliable index for mapping mangrove canopy density in dynamic coastal environments affected by tidal inundation. These findings demonstrate the effectiveness of combining Sentinel-2 red-edge information with field-based validation to support mangrove monitoring and coastal management.
