Reduksi Bakteri Total Dan Enterobacteriaceae Pada Campuran Lumpur Susu Dan Onggok Terfermentasi Oleh Aspergillus Niger (Reduction of Total Bacteria and Enterobacteriaceae on Waste Water Solid-Cassava Waste Mixed Fermented by Aspergillus niger)

Penelitian ini bertujuan untuk mengetahui reduksi bakteri total dan bakteri Enterobacteriaceae pada campuran lumpur susu dan onggok terfermentasi oleh Aspergillus niger. Penelitian menggunakan metode eksperimen dengan Rancangan Acak Lengkap (RAL). Penelitian ini menggunakan empat perlakuan berupa penambahan dosis inokulum (P0= 0%, P1 = 0,2%, P2= 0,4% dan P3 = 0,6%) dengan enam kali ulangan. Proses fermentasi selama tiga hari. Data yang diperoleh dianalisis dengan Uji Sidik Ragam kemudian perbedaaan antar perlakuan dilakukan dengan uji Duncan. Hasil penelitian menunjukkan bahwa: 1) Penurunan jumlah bakteri total dan Enterobacteriaceae oleh fermentasi Aspegillus niger berbeda sangat nyata (P < 0,01); dan 2) Penambahan inokulum 0,6% menghasilkan penurunan jumlah bakteri total (84,4%) dan Enterobacteriaceae (96,3%).

The study was conducted to know the reduction of reducing total bacteria and Enterobacteriaceae on dairy waste water solid-cassaca waste fermented by Aspergillus niger. This experiment was arranged based on Completly Randomized Design. The treatment consisted 4 inoculant doses (Po = 0%, P1 = 0.2%, P2 = 0.4% and P3 = 0.6%) and each of them was replicated 6 times. The process of fermentation was done in 3 days. The data was statistically analized by Analysis of Variance (ANOVA), then the different of treatment was analized by Duncan test. The results showed that, 1) Decreasing number of total bacteria and Enterobacteriaceae was significantly different (P < 0.01); 2) The addition of 0.6% inoculant resulted in decreasing of total bacteria (84.4 %) and enterobacteriaceae (96.3%).
