Variation pumakkal formula against NPK levels of Household liquid waste organic fertilizer

Abstract

More than industrial trash, household liquid waste is a societal concern caused by human activities. Using Pumakkal starters, this research turns domestic liquid waste into organic fertilizer. This research was conducted in several stages. The first was to make household waste liquid fertilizer with pumakkal formula P1 (3 bacterial isolates), P2 (6 bacterial isolates), P3 (9 bacterial isolates), P4 (12 bacterial isolates), P5 (15 bacterial isolates). The second was the test quality of household waste liquid fertilizers. The results showed the levels of NPK have quality standards of 2-6% with grades N (0,337), P (1,755), and K (3,818) at the highest treatment, and the values of N, P, K meet SNI. The C-Organic levels have a quality standard (minimum 10) with the value of 15,706 in the P5 treatment, and thus C-Organic exceeds SNI. The ratio level of C/N has a quality standard (≤25) with a value of 93,191 at the smallest P5 treatment compared to other treatments resulting in the ratio of C/N exceeding SNI. The pH has a quality standard (4-9) with a value of 6,176 on the P5 treatment, so the pH has met the SNI.
