摘要：Pineapple Liquid Waste Fertilizer (LCN) is a biological fertilizer derived from the main ingredient of pineapple liquid waste which is bioremediation with the help of indigenous bacteria in degrading organic matter. This study was to determine and see that LCN indigenous bacteria could not inhibit the growth of soil bacteria or indigenous bacteria could inhibit the growth of soil bacteria. This type of research is qualitative experimental research. the object under study to see whether or not there is a clear zone or zone of inhibition between two intersecting isolates. If there is an isolate it is said to be compatible, it means that there is no inhibition zone in the area where the two isolates meet, and it is said to be incompatible if there is an inhibition zone in the area where the two isolates meet. The isolates used in the antagonistic or competitiveness test were 15 isolates of LCN indigen bacteria and 6 isolates of soil bacteria in the Karang Rejo experimental garden, Metro Utara so that the combinations of challenged and challenged isolates were all 90 bacterial combinations. Based on the results of the study, it can be concluded that there is no antagonism between 15 pineapple liquid waste indigen bacteria (LCN) and soil bacteria in the Karang Rejo Metro Utara experimental garden.
