STUDI KETERSEDIAAN UNSUR HARA MAKRO PADA PROSES PENGOLAHAN LIMBAH CAIR INDUSTRI PERKEBUNAN KELAPA SAWIT PT FARINDA BERSAUDARA

Abstract

This research is motivated by the importance of managing liquid waste in the oil palm plantation
industry of PT. Farinda Bersaudara, whose aim is to determine the potential availability of
macronutrient content in their liquid waste, with the method used, namely by taking liquid waste in the
sewage treatment pond (1,5 and 8) with each pond taken a sample that is put in a bottle. 1.5 liter
packages in each pond, samples were packed and sent to the laboratory for analysis of macronutrient
content (N, P, K, Ca, Mg, Na and pH).The results showed that the content of macronutrients in the
liquid waste pond no 5 from the palm oil plantation waste treatment plant showed that the organic
chemical content was better than pond 1 and pond 8
