Reducing the number of microorganisms and organic carbon by implementation of APS (Advanced Ponds System) in the wastewater of dairy goat with added liquid probiotics

Abstract

<p class="MDPI17abstract"><strong><span lang="EN-US">Objective: </span></strong><span lang="EN-US">The </span><span lang="EN-US">activities<span> of the dairy goat group, in general, have not paid attention to the processing of livestock waste that comes from maintenance activities. For example, liquid waste from cleaning cages and livestock baths, dirt, urine, and milking activities. Dairy goat farm waste, if not appropriately managed can have a negative impact on the quality of underground water sources, surface water, and the surrounding environment. Application of the <em>Advanced Ponds System</em> (APS) system with at</span></span><span lang="IN"> part of</span><em><span lang="EN-US"> Algae Settling Ponds</span></em><span lang="EN-US"> pool size of 3 m x 1.5 m x 1.5 m with a dose of 50 ml / m<sup>3</sup> of probiotic liquid so that 337.5 ml </span><span lang="IN">was</span><span lang="EN-US"> needed.
