Abstract

 As a source of minerals, water must be continuously maintained, including in term of its quality. Meanwhile, swamps are wetlands that have the potential to experience a decline in water quality. The presence of river borders in swamps has been known to maintain their water quality. Vegetation cover of the river border is established through restoration activities in which it is expected, directly and indirectly, to improve water quality. This study aimed to investigate the water quality in swamp using the Water Quality Index (WQI). Surveys were carried out and samples were collected to determine the effect of restoration on river border in swamps. Samples were collected severally, namely prior to restoration (T0), first year (T1), third year (T3) and fourth year (T4) after restoration. The parameters for water quality of T0 and T1 include pH, DO, BOD, TDS, turbidity and nitrate, while for T3 and T4 include: pH, DO, BOD, TDS, temperature, phosphate, E. coli and nitrate. The findings indicated that the WQI of the swamp prior to restoration was greater than that at the first year of restoration due to the process of land clearing. Meanwhile, the WQI at the third year has improved compared to before the restoration and land clearing phase. It suggests that the presence of vegetation on river border is able to improve the water quality. At the fourth year, a fire in the upstream reached the area adjacent to the study site. It led to a decline in surface water quality and affected the water quality index. Furthermore, the abundance of aquatic biota was indicated by two taxa of zooplankton in the third year of restoration while none of them was identified in the fourth year. In overall, restoration activities on the river border improve the quality of water in swamps in a sustainable manner.

Abstract

After the looting and destruction of forest land in the Merubetiri National Park area were effortS to restore the area to its original condition. Various efforts were made involving the community in the rehabilitation of Meru Betiri National Park land. One indicator of the success of land rehabilitation is increasing biodiversity. The purpose of this study was to determine biodiversity in the rehabilitation area of Meru Betiri National Park. The method used uses a 100-200 m striped line combination at each location for vegetation data collection. Vegetation analysis by calculating type frequency, species density, species dominance, important value index, species diversity index, species richness index and distribution pattern. The results showed that there were 14 types of vegetation in 11 families in 4 common observation plots and jackfruit plants (Artocarpus heterophyllus) and showed adaptability and these plants were needed by the community. Based on the results of the study, the INP value of the Wonoasri plot was 103.27% Pete (Parkia speciosa), Bonangan plot was Jackfruit (Artocarpus heterophyllus) of 154.18%, Donglo plot of Jackfruit (Artocarpus heterophyllus) was 133.22%, and Jackfruit Pletes (Artocarpus heterophyllus) of 262.41%. For this reason, it is necessary to do new types of enhancements and compaction of spacing on each rehabilitation plot so that the value of diversity and species richness can increase, so that the success of rehabilitation can be seen.
