Abstract

The Lubuk Lampam floodplain’s ecosystem is naturally affected by the fluctuation of the water surface. This ecosystem also receives anthropogenic substances such as nutrients and other chemicals, especially from the oil palm plantation and its industrial processing activities. The main objective of this research was to determine the trophic status of the floodplain using the trophic level index (TLI) and Carlson’s trophic state index (TSI). The water quality and the fish samples were collected and analyzed from 7 stations representing various types of floodplain habitat. The results showed that the trophic status of Lubuk Lampam was hypereutrophic (very nutrient-rich). This was also supported by the high increase of the body weight (“b” value more than 3) and the high gonadosomatic index (GSI) of the studied fishes, i.e. Osteochilus vittatus 2.53-6.81% (male) and 3.00-15.86% (female); Helostoma temminckii 0.28-3.33% (male) and 1.30-10.43% (female); and Channa striata 0.33-0.59% (male) and 0.21-2.73% (female).

Abstract

Lake Toba is the largest lake in Indonesia, located in the Province of North Sumatra. Lake Toba is used to aquaculture, agricultural, tourism, and residential areas. These activities will produce organic and anorganic matter that can affect water quality and can cause eutrophication. Some indicators of eutrophication are an increase in phytoplankton biomass and changes in phytoplankton community structure. The aim of this study was to describe the phytoplankton community structure in Lake Toba. This study was conducted on 20-24 October 2014 at 23 stations around the Samosir Island, Lake Toba. The results showed that the phytoplankton abundance ranged 216-68.319.716 cells/m3. The phytoplankton composition consists of 35 genera from four classes: Cyanophyceae, Chlorophyceae, Bacillariophyceae, and Dinophyceae. Chyanophyceae is a dominant phytoplankton groups based on the composition of abundance (>40%). Structure of phytoplankton communities in Lake Toba dominated by Anabaena.

Abstract

ABSTRACT Wastewater from laboratory glassware washing activities contains organic materials. Decomposing bacteria could increase the biomass by utilizing organic matter as a source of carbon. This research was aimed to describe the influence of commercial probiotic application in reducing organic matter content of Proling laboratory wastewater. The research was conducted from February to July 2016 in Aquatic Microbiology Laboratory. The experiment consists of several treatments, those were wastewater (L), wastewater+molase (LM), and wastewater+molase+bacteria from commercial probiotic (LMB). Major parameters observed were COD and bacteria abundance. The results showed that there was significant response difference between molasses and without molasses treatment. Based on COD, the most influenced treatment in decreasing organic matter were LM and LMB. These treatments could decrease COD up to 97% and 91%. Furthermore, the abundance of bacteria in molasses treatment was higher than without molasses. Based on this study, the most effective treatment in reducing organic matter was LMB.  Keywords: bacteria, laboratory wastewater, molasses, organic matter

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

Abstract

Kondisi perairan muara sungai di Teluk Banten yang dipengaruhi oleh kondisi lingkungan, aktivitas kegiatan industri dan aktivitas manusia lainnya kemungkinan akan berpengaruh terhadap hasil tangkapan ikan di muara sungai tersebut. Tujuan dilakukannya penelitian ini adalah untuk mengkaji keterkaitan antara kualitas air dan hasil tangkapan ikan di muara - muara sungai di Teluk Banten. Pengambilan contoh air dan ikan dilakukan pada bulan Mei, Juli dan Oktober 2013 di empat stasiun, yaitu di Muara Sungai Wadas, Cibanten, Cengkok, dan Pamong. Beberapa parameter fisika dan kimia dianalisis. Pengambilan contoh ikan mengikuti operasi penangkapan ikan nelayan setempat, selanjutnya ikan dihitung jumlahnya dan diidentifikasi jenisnya. Kualitas air dianalisis dengan metode Indeks Pencemaran. Tingkat kesuburan perairan ditetapkan dengan metode TRIX. Hasil tangkapan ikan dianalisis indeks keanekaragaman, indeks dominansi dan kelimpahan relatifnya. Keterkaitan antara kualitas air dengan hasil tangkapan ikan di perairan muara sungai Teluk Banten dilakukan menggunakan analisis CCA (Canoconical Correspondence Analysis) lalu dibuat matriksnya untuk setiap waktu pengamatan. Kualitas air di empat muara sungai tergolong tercemar ringan. Tingkat kesuburan perairan di keempat muara tersebut berkisar dari eutrofik sampai hipertrofik. Berdasarkan analisis CCA, parameter arus, suhu air, salinitas, dan amonia berkorelasi dengan keberadaan ikan-ikan di Muara Sungai Wadas, Cibanten dan Cengkok, sedangkan keberadaan ikan belanak (Mugil cephalus) di Muara Sungai Pamong lebih berkorelasi dengan kondisi parameter daya hantar listrik, TSS, dan pH. Berdasarkan matriks hubungan antara kualitas air, tingkat kesuburan perairan, dan hasil tangkapan ikan, dapat disimpulkan bahwa kualitas air yang tercemar ringan dengan tingkat kesuburan yang tinggi, membuat hasil tangkapan di muara - muara sungai Wadas, Cibanten, Cengkok dan Pamong di Teluk Banten tergolong masih cukup tinggi.
