Makrozoobenthos sebagai Bioindikator Kualitas Air Sungai di Sub DAS Ciliwung Hulu

Macrozoobenthos has a relatively sedentary nature and the very limited movement which will directly affected in the event of changes in water quality, therefore markozoobenthos often used as bio-indicators of water quality. This research was conducted form March to June 2015 in the Ciseuseupan sub watershed, Cisukabirus sub watershed and Cisuren sub watershed with the purpose of determining level of water quality and influence of land-use on the quality water by using macrozoobenthos community structure. Biological indices were used to analyze the macrozoobenthos are FBI and SIGNAL2. FBI values in the Ciseseupan sub watershed are 5,02 with criteria the quality of water moderate, in Cisukabirus sub watershed are 3,96 with criteria the quality of water very good and in Cisuren sub watershed 4,37 with criteria the quality of water good. Extensive use of forest land larger than the residential land use in Cisukabirus sub watershed were the major factor in the high quality in the sub watershe

Uji Nefrotoksik dari Ekstrak Etanol Biji Mahoni (Swietenia Mahagoni Jacq.) terhadap Tikus Putih Jantan Galur Wistar

Telah dilakukan penelitian uji nefrotoksik dari ekstrak etanol biji mahoni (Swietenia mahagoni Jacq) selama 40 hari satu kali sehari secara oral pada tikus putih jantan dewasa galur wistar sebanyak 24 ekor yang dibagi menjadi 4 kelompok. Satu kelompok diberikan aquadest (kontrol), kelompok yang lain diberikan ekstrak etanol biji mahoni dengan dosis masing-masing 25,48 mg/200gBB, 50,96 mg/200gBB, dan 76,44 mg/200gBB. Dari hasil penelitian ini didapat pada dosis 25,48 mg/200gBB terjadinya penurunan kadar ureum dan kreatinin jika dibandingkan dengan kontrol, sedangkan pada dosis 50,96 mg/200gBB,dan 76,44 mg/200gBB terjadinya peningkatan kadar ureum dan kreatinin. Dari data statistik Anova satu arah terlihat kadar ureum setiap kelompok perlakuan berbeda sangat signifikan (P<0,01). Dilanjutkan dengan uji Duncan, diperoleh pada dosis 50,96 dan 76,44 mg/200 gBB menunjukkan bahwa ekstrak etanol biji mahoni (Swietenia mahagoni Jacq.) juga tidak berbeda secara bermakna. Sedangkan pada kreatinin dari data statistik T-test independent juga terdapat perbedaan sangat signifikan (P<0,01). Dari data tersebut diketahui pada dosis 50,96 mg/200gBB dapat menyebabkan terjadinya nefrotoksik
