Background: Contamination of freshwater ecosystems has become a major issue as it threatens public water sources as well as aquatic life. It is important to predict changes in organism health, given a known number of environmental factors and pollutant concentrations, in order to better manage contaminants through biomarker analysis. This study aims to examine the ecosystem health of the Brantas River based on its environmental condition and the hematology profile of Gambusia affinis fish present in the river. This species was chosen because of its wide distribution along the Brantas River, and because it is very tolerant, adaptable, highly abundant, and easy to catch. Methods: The study area included 10 sampling sites along the Brantas River watershed. In total, six water quality parameters were observed (temperature, pH, dissolved oxygen (DO), biological oxygen demand (BOD), ammonia concentration, and phenol concentration) and hematology measurements consisted of erythrocyte, leucocyte, and micronuclei analyses. Results: The results showed that the upstream area of Brantas River, located in Batu, was the least polluted region, while Mojokerto was the most polluted. The erythrocyte level of Gambusia affinis caught in most sampling sites was quite low. Furthermore, research revealed that the status of Gambusia affinis' hematological profile was significantly correlated (p<0.05) with water quality parameters, particularly DO, BOD, ammonia, and phenol. Conclusions: It can be concluded from these results that the hematological profile of the fish is poor due to high levels of organic waste and harmful substances.

“…Salah satu wujud pengamanan daerah hulu sebagai wilayah pengaman sumber mata air sungai adalah dengan menjadikan lokasi sumber mata air sungai Desa Sumber Brantas sebagai lokasi Arboretum (Widiatmono et al, 2017;Indarto et al, 2019). Dalam kaitannya usaha pengamanan tersebut dapat menunjang terlaksananya usaha konservasi lahan dan konservasi air di daerah hulu dan sekitarnya dengan kegiatan yang bersifat vegetatif (penghijauan) dan kegiatan yang bersifat teknis termasuk pembuatan bangunan pengendali sedimen .…”

The level of land-use change in the Brantas watershed includes encroachment in the upstream area of the spring which has been increasingly massive since the 1960s, and reached the highest level in the late 1990s which driving the watershed damage. The damage in the upstream area encourages the need to increase resilience by building The Sumber Brantas Arboretum Area. This area is equipped with sedimentary control structures to ensure the long-term sustainability of the arboretum. A recent study of the rainfall plan and the security level of the sedimentary control building to the arboretum became an interesting thing to be reviewed. The analytical approach used in this study is quantitative. The method used for flood design analysis uses three methods including Log Pearson Type III Method, Gumbel Method, and Iwai Method. The selected hydrograph is the Nakayasu Hydrograph. Hydraulics analysis of sediment control buildings using HEC-RAS tools with several other hydrological calculations. The results of the analysis in the Sumber Brantas Arboretum Area showed that the design flood discharge (Q) was 59.35 m3 / sec. In flood design conditions with its own weight, the åf of the sediment control building is 42.2 (higher than the minimum safety level) and it is relatively safe, either in normal or in an earthquake condition. In the design flood conditions with full sediment storage, the Sf of sediment control buildings is 1.6 (higher than the minimum safety level) so that it is relatively safe, either in normal or in an earthquake condition.
