Pengaruh Penambahan Zeolit pada Proses Pelletizing Limbah Penetasan Terhadap Kandungan Coliform dan Salmonella Produk Pellet
ABSTRACT: Experiment to study effect of administering zeolite in the pelletizing hatchery wastes on the total Coliform and Salmonella was done in the Laboratory of Feed Technology, Faculty of Animal Science and Agriculture,University of Diponegoro. Zeolite has been reported have binding capacity on wide range of chemicals, including toxic compounds, and interfere the activity of microbes. Administrationzeolite in the pelletizing of hatchery wastes areexpected to reduce the total Coliform and Salmonella in the pellet products, therefore improved the safety of the pellet products as an alternative feed ingredients. Doses of zeolite administration in the pelletizing are 0, 2, 4 and 6%. Data were analyzed by analysis of variance (ANOVA) followed by Duncan's multiple range test. The results showed, effect of administering zeolite in the pelletizing hatchery wastes was significant to the total Coliform (P <0.01). Increasing doses of zeolite reduced the Total Coliform and the Salmonella was not detected in the hatchery waste pellets. It could be concluded that pelletizing hatchery waste with a dose of zeolite of up to 6% proven to reduce the content of Coliform and Salmonella in the pellet products.
