Abstract

Sempor Reservoir is one of the reservoir in Central Java. This reservoir has primary function as irrigation and hydropower source. Beside, it also has some benefit for fisheries and tourism activities. Reservoir utilization which has not been optimum yet need some adjustments with water quality and aquatic trophic state in Sempor Reservoir. This study was aimed to determine water quality and aquatic trophic state of Sempor Reservoir. This study was conducted from January to March 2014 with monthly water sampling. Survey method to collect data with stratified random sampling was used for four represented station. Aquatic trophic state determination was based in Carlson Trophic State Index (TSI) measurement. This method used some represented parameters of physics, chemistry and biology such as water transparency, total phosphorus, and chlorophyll-a. The results showed that water quality of Sempor Reservoir was still good for fishery activities. Aquatic trophic state of Sempor Reservoir based on Carlson TSI was classified to low-medium in euthropic category ranging from 50.71-64.91. Inlet was the only area which had medium category of eutrophic due to highly nutrient content derived from anthropogenic activities nearby.

Abstract

Perairan rawa banjiran Lubuk Lampam (RBLL) merupakan ekosistem khas yang mempunyai arti penting terutama secara ekologi sebagai habitat ikan khas rawa banjiran. Penelitian ini bertujuan untuk mengetahui karakteristik kualitas air di RBLL terkait dengan perubahan muka air dan adanya masukan bahan antropogenik terutama dari kegiatan perkebunan kelapa sawit yang berada di dalam dan sekitar area RBLL. Hasil penelitian ini menunjukkan bahwa curah hujan merupakan faktor utama yang mempengaruhi perubahan muka air di RBLL. Fluktuasi muka air yang tidak ekstrim sebagai akibat dari curah hujan yang relatif merata sepanjang tahun menyebabkan karakteristik kualitas air antar periode musim menjadi cenderung sama. Secara umum, karakteristik kualitas air RBLL dicirikan dengan pH cenderung asam, kandungan oksigen rendah, kekeruhan tinggi serta konsentrasi total nitrogen dan total fosfor yang tinggi. Bahan antropogenik berupa herbisida dari jenis paraquat dan glyfosat ditemukan dalam konsentrasi relatif kecil (rataan 0,004 mg/L dan 0,003 mg/L), sehingga berdasarkan nilai resiko (Risk Quotient, RQ) kedua jenis herbisida ini memiliki resiko ekobiologi rendah (<0,01) sampai dengan sedang (0,01<RQ≤0,1).

Abstract

ABSTRACTPerifiton is one community of organisms that can adapt and thrive in the river, and relatively settled in one location. Riparian vegetation in the Mountain Halimun-Salak National Park could be expected to affect the community structure of periphyton. The purpose of this study was to identify the community structure of periphyton on different vegetation canopy coverage, to analyze relationship between the communities structure of periphyton and upstream Cisadane water quality conditions, and to determine water quality based on perifiton community. There were three sets three stations based on canopy coverage (80%, 60%, dan 40%). The results showed two groups of stations, the high canopy coverage (80%) and the low canopy coverage. The highest perifiton abundance was found at stations low canopy coverage, that dominated by Bacillarophycae, Pennales order, especially Navicula with higher rate of succesion than the higher canopy caverage. Abundance of periphyton of low canopy coverage was affected by ammonium, turbidity, and water current. Furthermore, in stations high canopy coverage it was influenced by orthophosphate and currents. As a whole, the periphyton community at upstream of Cisadane indicated a good condition of water quality.Keywords: canopy, periphyton, succession rate
