ANALYSIS OF NITROGEN PHOSPHAT POTASSIUM IN LIQUID ORGANIC FERTILIZER BASIC WASTE LIQUID TOFU WITH VARIATION OF TOMATO MOLE

Abstract

Utilization of tofu liquid waste can be used as a new alternative to fertilizer because the tofu liquid waste it has the availability of nutrients needed by plants with the addition of Tomato Mole. The purpose of this study was to determine the quality of liquid organic fertilizer using tofu liquid waste as raw material with the addition of a variety of MOL Tomato (Solanum Lycopersicum) bioactivator.

This type of research is experimental research with a posttest only design. This study used tomato MOL variations (15 ml, 20 ml, 25 ml) with 3 repetitions in each treatment within 14 days of fermentation. Data collection techniques used pre-experimental and documentation methods. result analysis technique with table adds parameters to analysis.

Nitrogen, Phosphate, and Potassium content in liquid organic fertilizer using 1 liter of tofu liquid waste as raw material with the addition of various moles of tomatoes fermented for 14 days, namely 15 ml (1.5%), 20 ml (2%) and 25 ml (2 ,5%). In the variation of 15 ml ( 1.5%) the resulting Nitrogen, Phospat, and Potassium Nitrogen, Phospat, and Potassium content of (2.10%), variation of 20 ml (2%) resulted in the content of Nitrogen, Phospat, and Potassium of (2.33%), and in the variation of 25 ml (2.5%) resulted in the content of Nitrogen, Phospat, and Potassium of (3.45%) of the three variations already meeting the quality standards, namely PERMENTAN RI NO. 261/KPTS/ SR.310/ M/ 4/2019 ie 2- 6 %.

In this study, it is necessary to conduct further research by reviewing the length of fermentation time to obtain optimal results of Nitrogen, Phospat, and Potassium content, laboratory examination of the MOL content of tomatoes before the research process is carried out to determine the levels of N, P, K in tomato MOL.
