This study involves detailed observations of erosion indicators within the watershed to produce a comprehensive mapping of erosion patterns. The detailed mapping of erosion patterns and spatial distribution, along with the factors influencing erosion, is essential. Mapping erosion spatially often yields data that may differ from the actual erosion conditions observed in the field, there is a need for a more accurate yet efficient mapping of erosion hazard levels by combining spatial analysis methods and field surveys. The primary focus of the research is to develop an efficient erosion mapping survey procedure at the Micro Watershed Scale, considering diverse erosion typologies and land-use dynamics. The Micro Watershed of Parangtritis, chosen for its unique erosion characteristics, was used as the main research area. This mapping method involves a combination of field surveys and geospatial analysis to capture various erosion features. Important data to collect are various erosion and landform features based on their geomorphology and anthropogenic features. The mapping results demonstrate complex erosion patterns. Topography, vegetation cover, anthropogenic, and soil types play key roles in erosion distribution. Steep slopes and insufficient ground cover vegetation significantly contribute to the soil erosion. In the upstream area of the watershed, characterized by steep topography and a predominantly natural anthropogenic, there is a tendency for severe erosion, including 8.87 ha (6.38%) classified as Very Severe, 16.81 ha (12.08%) as Severe, 23.46 ha (16.87%) as Catastrophic, and 11.81 ha (6%) as High. Meanwhile, in the downstream area with relatively flat topography and an urbanogenic and agrogenic, erosion tends to be light, with 23.34 ha (16.78%) classified as Light, 7.08 ha (5.09%) as Moderate, and 28.63 ha (30.98%) as Very Light. These findings reveal diverse evidence of erosion, including splash erosion, sheet erosion, rill erosion, gully erosion, and landslides, and influenced by variations of topography, vegetation cover, anthropogenic, and soil types that significantly contribute to the erosion patterns within the watershed. Special attention is given to micro-sized erosion features that may not be visible through broader mapping methods. This detailed mapping approach provides valuable insights into the spatial distribution of erosion, facilitating more targeted conservation efforts. These findings contribute to a deep understanding of erosion patterns in the karst environment and provide fundamental information for soil and water conservation planning. In the context of environmental sustainability, detailed-scale erosion mapping in the Micro Watershed Area needs to further explore the anthropogenic influences on erosion occurrence.

The existence of a silvofishery system is expected to enhance the productivity of local communities in shrimp farming, specifically for the tiger shrimp. Efforts that need to be made in the development of tiger shrimp farming with a silvofishery system must be well-evaluated for land suitability. Land suitability analysis for pond cultivation needs to be conducted as a basis for decision-making regarding land use that is compatible with its suitability. This research was conducted in the community ponds in Lubuk Damar and Sungai Kuruk III villages, Seruway District, Aceh Tamiang Regency, Aceh Province. The study was carried out over four months, from August to November 2023. This research used a survey method with descriptive techniques based on field observations and laboratory analysis. The approach used in this survey research is an evaluative approach. The method employed in this study is a matching method. Based on the results of the land suitability evaluation at the research locations, it was found that there was an S3 (Marginally Suitable) land suitability class at three sample points, while an N1 (Currently Unsuitable) land suitability class was found at the fourth sample point. The limiting factors identified in this study include climate (precipitation), mangrove density, clay content, and ammonia levels. Improvement efforts to achieve an S1 land suitability class for mangrove density include reforestation or replanting mangroves to maintain the mangrove ecosystem. Additionally, efforts to improve clay content to reach an S1 land suitability class, which is currently too high, can be done by applying lime. High ammonia levels can also be addressed to achieve an S1 land suitability class by controlling water quality and creating water circulation. However, the climatic limiting factors present at the research locations cannot be improved, as they are natural factors.

Seblat Natural Tourism Park is substantial for the well being of Sumatran Elephant which provides suitable habitat in Bengkulu Province. The conversion of former production forest area with Particular Function of Elephant Training Center of Seblat into Convertible Production Forest Area of Seblat as wide as 710 hectares in 2011, and forest enroachment activities resulted in fragmentation of Sumatran Elephant habitat. This fragmentation led to the isolation of Seblat Natural Tourism Park and separation from surrounding forest area, which affects the species abundance of Sumatran Elephant. A study is required to understand the relationship between land cover change and dynamics of species abundance of Sumatran elephant during the period of 2011-2020. The study was conducted in the TWA Seblat with the area of ±7,768.36 hectares. Data used in this study were secondary data, particularly inventory data of Sumatran Elephants from the BKSDABengkulu which was obtained using the path transect method from patrol activities as many as ±228 patrols for ±1596 days, and land cover data which was obtained from the Directorate of Forest Resources Inventory and Monitoring, Directorate General of PKTL. Spatial analysis was carried out by performing topology test using ArcGIS 10.4 software and land cover classification based on SNI 7645:2010. Topology test resulted in 1 forest cover class and 6 non-forest cover classes. Statistical analysis carried out was multiple linear regression using the IBM SPSS 26 application by performing the Anova test or F test, and T test. The results of multiple linear regression analysis showed the correlation value (R) 0.753 indicated that there was close relationship between secondary dryland forest (X1) and shrubs (X2) with the dynamics of the species abundance of Sumatran elephant (Y). The contribution of variable X1 and variable X2 in influencing variable Y was56.7%, and 43.3% was influenced by other variables which unincluded in this study. The calculated F value is 3.935 with p value 0.081, andbecause the p value is higher than 0.05, simultaneously secondary dryland forest (X1) and shrubs (X2) did not influence the dynamics of the species abundance of Sumatran elephant (Y). The calculated T value is 1.776 with value of p=0.126, because value of p is higher than 0.05, partially there is no significant influence between secondary dryland forest (X1) on the dynamics of the species abundance of Sumatran elephant species (Y). Determining the influence of shrubs (X2) on the dynamics of the species abundance of Sumatran elephant (Y) resulted in T value of 2.579 and value of p=0.042, with value of p is lower than 0.05 means that there were significant effect between the two variables.
