This study aimed to recognize the role of mangrove forestas biofilters in controlling water pollutants of Pb and Cu that is predicted containing the mangroverehabilitation areas along Donan River banks, Cilacap. The research site was grouped into fourareas, which are control zone (three km before the point source), Inner Zone (at the point source),middle zone (one km point source), and outer zone (estuarine). Four plots were established tomeasure chemical water quality and mangrove tree density. Data colected were then analyzed usingregression model to identify the relationship between mangrove tree density and Pb and Cuconcentration in the water, substrate, roots, and leaves of Rhizophora apiculata. Analysis of variancewere applied among four zones to find out the role of mangrove as biofilters for those heavy metals.The results showed that ...

This study aims to identify criteria for determining ecosystem services in GOS, to study the conditions and distributions of potential ecosystem services in the Urban Area of Yogyakarta (UAY)’s GOS, and optimize the existing ecosystem services in GOS. The research’s locations include GOS in UAY consisting of urban forests, city parks, riverbanks, and greenbelts, for a total of twelve research locations. The identification of the criteria for GOS was accomplished with the expert opinion and comparative methods resulting in weight values. The field data and expert assessments were analyzed through a scoring analysis to quantify the level of ecosystem services in each research location. This data was further analyzed by examining the area allotments within the existing regulatory framework to the determine the conditions of GOS with optimal ecosystem services. The results of the study show th...

This study aims are to identify green open space criteria value for determining ecosystem services, to study the conditions and distributions of ecosystem service potentials of Green Open Spaces in Urban Area of Yogyakarta, and optimize Green Open Spaces in the Urban Area of Yogyakarta in the perspective of ecosystem services. The research locations included Green Open Spaces of Urban Area of Yogyakarta consisting of urban forests type, city parks, river borders, and road greenbelts, comprising of twelve research locations. The identification of the criteria for Green Open Spaces was done using the expert judgment and pairwise comparison methods resulting in weight values. In each observation location, a plot was made for monitoring the conditions of each Green Open Space criterion using a score. The data from the field and the assessment by experts were analyzed by means of scoring analysis to find out the level of ecosystem services in each research location and they were further descriptively and deductively analyzed by taking account of the area allotment and the available regulations to attain the conditions of Green Open Spaces with optimal ecosystem services. The results of the study show that of the sixteen criteria under study, each plays a role in ecosystem services. The values of ecosystem services of Green Open Spaces in KPY show different values for each type of Green Open Spaces. In general, the types of urban forests, including Urban Forest of Arboretum of Faculty of Forestry, Gadjah Mada University, and Arboretum of Gembira Loka Zoo, have ecosystem services in the high category for the eleven ecosystem services, while the types of Green Open Spaces of city parks, including Denggung Park, Gajah Wong Educational Park, and Lalu Lintas Park, and riverbanks, including Code's riverbank, Gajah Wong's riverbank, and Winongo's riverbank, on the average have ecosystem service values in the moderate category, and the types of Green Open Spaces of street greenbelts, including greenbelt of Jalan Magelang, greenbelt of Jalan Cik Di Tiro, and greenbelt of Jalan Malioboro, all have ecosystem service values in the low category. Based on the results, optimalize Green Open Spaces in KPY in the perspective of ecosystem services can be done by optimizing each criteria with the highest weight value adjusted to the allotment of each type of Green Open Spaces and the regulations related to Green Open Spaces.
