Abstract

Pond Cibuntu is one of the urban ponds located in Bogor Regency, West Java Province. With a maximum surface area of 2.11 ha and maximum depth of 1.20 m, the pond serves as retention pond and recreational fishing. Ponds in urban areas can be disturbed due to siltation, land conversion, and anthropogenic activities that can influence the physico-chemical conditions of the waters. The aims of this study was to evaluate the physico-chemical properties of the Pond Cibuntu as basis for freshwater ponds management. This study was conducted from September to December 2018 at five observation stations. The results of this study showed that the parameters of water temperature, TDS, pH, DO, and total phosphorus still meet the class III of water quality standards according to Government Regulation Number 82 of 2001. The value of total nitrogen and total phosphorus indicates Pond Cibuntu which is eutrophic to hypereutrophic.

Abstract

To alleviate the consequence of severe biodiversity threats, fifteen national priority lakes to be rehabilitated have been declared in Indonesia. Lake Sentarum National Park (LNSP), one of the lakes, is a distinctive floodplain lake that exhibits significant vegetation and flora diversity. One particular ecosystem type in the area is dwarf swamp forest vegetation, which displays enormous amounts of floral vegetation in that area. This study intends to uncover vegetation data in the dwarf swamp forest habitat, which currently has relatively limited data series about its diversities. The vegetation specimens were collected using a 50 x 50 m line transect. Fourteen species from ten families were collected from six observation stations. The most prevalent vegetation is C. cf. ensifolius, I. mentangis, and B. acutangula. The species diversity index (H') is 1.78 (low category), and the small lake area has a greater species variety than the river area in the LNSP area. Furthermore, we found that dwarf swamp forest vegetation is mainly used as food for Apis dorsata honey bees to produce forest honey. The findings of this study will be helpful as a fundamental reference for future monitoring, research, and conservation efforts in the park.
