The mangrove forest is a very productive ecosystem, both economically and ecologically. Mangrove forests can protect settlements, buildings, and agriculture on the coast from strong winds or seawater intrusion, support the livelihoods of coastal communities and store high carbon stocks. Regardless of its role, the Taman Hutan Raya Ngurah Rai Mangrove Forest continues to be threatened by human activities. This study aims to monitor changes in the area, health, and water quality of mangrove forests. The data used are Landsat 7 ETM + imagery and Landsat 8 OLI in 2010-2020. We used NDVI vegetation indices to analyze mangrove health and Total Suspended Solid (TSS) to investigate the water quality of the mangrove forest. Temporal water quality parameters are obtained by using the TSS algorithm on Landsat imagery. The results showed variations in mangrove forest area changes, NDVI values, and water quality. In 2010 - 2015 Mangrove Forest Area increase by 117.72 ha but decrease in 2015-2020 by 96.21 ha. Mangrove health was also improved in 2010-2015 but the decline in 2015-2020. Meanwhile, mangrove forest water quality seen from the TSS distribution tends to grow from 2010 to 2020.
Water resources in Sukarame Village, Cisolok Subdistrict, Sukabumi Regency are not only used for fulfilling the daily needs but also for agricultural irrigation and mining activities. Sukarame has an Unlicensed Gold Mine (PETI) that dumps waste directly into the river, which can affect the quality of Sukarame Village’s water resources. Water quality monitoring is useful to prevent a decrease in the quality, water utilization that can interfere with quality, endanger health, as well as improve water quality. The purpose of this study was to determine the quality and utilization of water resources in Sukarame Village. The method used in this study was descriptive by taking 15 samples from 4 hamlets in Sukarame Village originating from surface water and groundwater. The water quality of the sample was tested for physical and chemical parameters of water. Water quality data then analyzed under Health Minister Regulation No.416/MEN.KES/PER/IX/2010 concerning Water Quality Requirements and Supervision. The measurement of water resources quality taken from groundwater and surface water sources in Sukarame Village varies, therefore the use of water resources is also different. Surface water resources of Sukarame Village cannot be used for daily needs because the turbidity is high, while groundwater resources included in clean water can be used for daily needs.
Mangrove forest is a very valuable forest, but despite its benefits mangrove forest continue to be degraded due to human activities. The purpose of this study was to map the distribution and to analyze mangrove forests’ health based on the NDVI vegetation index value and environmental quality. Distribution of mangrove forest health was obtained through the processing of sentinel 2-A satellite imagery in 2020 and field measurements. The environmental quality of the mangrove forest was obtained by processing the physical parameters which are water temperature, water salinity, water pH, and substrate texture using the Ordinary Kriging method. The health of the mangrove forest of Taman Hutan Raya Ngurah Rai is dominated by healthy category mangroves. The health of the mangrove forest worsens when closer to the shore and riverbanks. Mangrove vegetation with good conditions tends to have optimal environmental quality conditions and vice versa.
