Abstract

Drones are unmanned aircraft that are controlled by robotic systems and computer systems remotely by pilots on the ground. Drones are able to see the condition of forest areas such as identifying environmental changes and monitoring large areas, it is difficult and time consuming if carried out using land vehicles or on foot can be done easily by simply flying the drone. The use of drone technology can help the management of the Hasanuddin University Education Forest to solve the problem of forest encroachment from time to time. The educational forest area of ​​Hasanuddin University has an area of ​​1,460.50 ha and there are several lands that have been used by the community. Therefore, in this study, identification of community land use in the Education Forest area was carried out by looking at the results of drone aerial photos. The research variable is the recording of land use in the forest in the form of aerial photographs. The photo recording results are combined using agisoft to produce a perpendicular image with a resolution of 8.2 cm – 20.3 /pix. In the identification of land use, it is done using ArcGIS Software. The results of the study illustrate that community use in the forest is in the form of dry land agriculture and rice fields covering an area of ​​33.3 ha or 19% of the total area of ​​the Bengo-Bengo Education Forest area of ​​Hasanuddin University. The occupation that occurs in the Hasanuddin University Education forest is a claim of ownership over land in the forest area. The use of drone technology can help the management of the Hasanuddin University Education Forest to solve the problem of forest encroachment from time to time.

Abstract

This study investigated the diversity and density of rhizosphere fungi in the post-nickel mining land of PT. Vale Indonesia Tbk., to assess its potential in supporting revegetation and ecological recovery. By analyzing fungal populations at various dilution levels in PDA media, this study revealed the relationship between post-reclamation duration and increased soil microbiological activity. The results showed that longer reclaimed land had denser fungal populations, especially at lower dilutions, indicating the importance of rhizosphere fungi in soil health recovery. This study confirmed that the presence of plants significantly affected the abundance and diversity of rhizosphere fungi. These findings provide insight into the importance of selecting specific fungal species for post-mining land revegetation strategies, which support plant growth and accelerate ecological recovery. It can contribute to developing best practices in ecological engineering and environmental management in post-mining areas.

Abstract

Population growth and land conversion have led to the degradation of mangrove forests on the southern coast of South Sulawesi, especially the Mamminasata area. Reduced mangroves increase carbon dioxide in the atmosphere. However, data on the potential carbon absorption of mangroves is still lacking. To overcome this, remote sensing is used to estimate carbon reserves. This reseach utilises Sentinel-2A imagery to estimate mangrove carbon stocks in Mamminasata. The image processing process includes radiometric correction, atmospheric correction, image classification, and extraction of NDVI values. The NDVI value is used to classify the density of mangroves into sparse, medium, and dense, covering 1,244.75 hectares. Field data collection was carried out through a survey of forest stand measurements. The results of NDVI transformation show a value range of 0.2 to 0.8 for mangrove objects in the Mamminasata area. The NDVI data on the analysed images were then made into three density classes. The rare density class has a carbon value of 3.56 – 21.16 Ton C/ha, the medium density class is between 21.17 – 31.49 Ton C/ha, and the dense density class is between 31.50 – 39.18 Ton C/ha. Regression analysis shows a strong correlation between NDVI and carbon stock (R² = 0.7134). This study confirms the effectiveness of remote sensing in environmental monitoring and mangrove conservation. These findings support conservation efforts and sustainable management policies by highlighting areas with high carbon sequestration potential.

Abstract

Remote sensing technology has become crucial in vegetation monitoring, particularly for assessing vegetation density. Despite its broad application, its use in evaluating land rehabilitation efforts remains limited. The increasing extent of degraded lands has underscored the importance of effective forest and land rehabilitation activities. Traditionally, evaluating these efforts involves direct site visits to monitor plant growth annually for three years post-planting, which is time-consuming, labor-intensive, and costly. According to rehabilitation standards, a program is successful if 75% of the planted vegetation survives until the end of the third year. This study presents an efficient alternative by evaluating a rehabilitation site in Maros Regency, using remote sensing technology to monitor planting success over periods of 15 years (2007), nine years (2013), and three years (2019). The evaluation utilizes multispectral drone imagery and Normalized Difference Vegetation Index (NDVI) analysis to assess vegetation density through multi-temporal analysis across wide areas. The findings reveal that the percentage of forested areas after three, nine, and fifteen years of rehabilitation activities was 24.6%, 3.1%, and 23.5%, respectively. This research demonstrates the potential for further application of Unmanned Aerial Vehicle imagery in monitoring the success of land rehabilitation projects.

Abstract

Land-use change significantly affects carbon emissions, particularly in rapidly growing cities such as Makassar. This study uses geospatial technology to analyze the impact of land cover changes on carbon emissions and sequestration in Makassar City from 2022 to 2041. The Rapid Carbon Stock Appraisal (RaCSA) method and the QUES-C feature of the LUMENS software were utilized to model land cover changes based on the Makassar City spatial planning scenario (RTRW). The results indicate that expanding residential areas and reducing green spaces, such as mangrove forests and agricultural land, have increased carbon emissions. However, carbon sequestration in certain areas, especially in the Tallo District and reclamation areas, has increased significantly due to the establishment of local protection zones. This study highlights the importance of spatial planning that supports the protection and restoration of green spaces to enhance carbon sequestration capacity and support sustainable development strategies in Makassar City.

Abstract

This study investigates the changes in flood inundation areas in the Lamasi Watershed, focusing on the integration of HEC-RAS and SWAT models from 2013-2022 with projections up to 2031. This research is motivated by the increased frequency and extent of flooding in DAS Lamasi, attributed to land use changes and hydrological variability. The methodology employed involves hydrological simulation using the SWAT model to estimate river discharge based on historical land use, climate, and topography data. The output from the SWAT model is then integrated into the HEC-RAS model to simulate flood distribution and extent. The Flow Regime Coefficient (KRS) is also analyzed to assess flow quality and identify flood risk indicators. The results indicate an expected increase in flood inundation area from 1,825.88 hectares in 2021 to 1,860.62 hectares in 2031. The KRS analysis reveals that 17 sub-basins in poor condition in the downstream areas exhibit a high risk of flooding. Based on these findings, the study recommends the development of mitigation strategies including enhanced drainage infrastructure and more effective land management. This study provides crucial insights for the planning of flood management and risk mitigation in DAS Lamasi, supporting efforts to adapt to the impacts of land use changes and climate dynamics in the future.
