Analysis of the Nutrient Content of Liquid Organic Fertilizer (POC) Household Organic Waste in Rimba Jaya Village, Merauke Regency Using the Stacked Bucket Method

Abstract

The purpose of this study was to analyze the nutrient content of POC produced from household waste using the stacked bucket method. This research was conducted for 3 months from September to November 2020. This research is a descriptive study. The first process is the process of making organic fertilizer from household waste which is fermented in a stacked bucket for 2 months. Leachate from organic waste is dried in the sun for one month or until the leachate is blackish in color and has no more subtle aroma. The finished POC is sampled and tested in the laboratory to determine the content of micro and macro nutrients as well as organic C. To measure the content of macro and micro nutrients, the test material used was Kjeldahl for nitrogen content while P, K, Fe, Mn, Cu, Zn, S, Ca, Mg, Na used spectrometric wet oxidation method and the content of C-organic by spectrophotometric method. The test results showed that the POC of household waste contained 0.08% total N, 0.07% total P, 0.28% total K, 5 ppm total Fe, 0.4 ppm total Mn, 0.0 ppm total Cu, Zn total 0.6 ppm, total S 0.5%, total Ca 165.0 ppm, total Mg 106.9 ppm, total Na 172.7 ppm, organic C 1.06%, and C/N ratio 13.27.

Chemical Characteristics and Plant Growth Regulators of Organic Waste as Liquid Organic Fertilizer

“…This finding was supported by [19] that organic carbon content decreases during the fermentation process because organic carbon is used as a source of microbial energy during fermentation. [10] added that POC from fruit waste (banana, papaya, watermelon peels) and vegetable waste had levels of N, P2O5, K2O, Fe, Mn, Cu, and Zn nutrients that did not close to the quality standard of LOF.…”

“…Several researchers have reported agricultural organic waste that can be used to improve the growth of horticultural crops, such as eggshell waste, moringa leaves, and onion peel for pakcoy growth [5][6][7]; waste of sugarcane leaves and banana peels for lettuce growth [8,9]. Several researchers have also reported macro and micronutrient content from agricultural organic waste [10][11][12][13][14][15]. In addition, several extracts from organic waste had the plant growth regulators that can stimulate plant growth and development, such as banana hump and onion which had the PGR namely indole-3-acetic-acid (IAA), gibberellic acid (GA3), and zeatin [16]; moringa leaves had the PGR of IAA, zeatin, GA3, and abscisic acid [17].…”

Pengenalan Metode Ember Tumpuk Sebagai Upaya Pengolahan Sampah Organik Rumah Tangga Di Kawasan Perkotaan

“…Penggunaan ember tumpuk dalam pengolahan sampah organic rumah tangga dinilai dapat menjadi jawaban dari pencemaran lingkungan. Selain mudah diaplikasikan, bahan dan alat untuk membuat ember tumpuk ini sangat mudah didapatkan karena dapat menggunakan alat-alat bekas (Mangera & Ekowati, 2022). Metode ember tumpuk terbukti dapat meningkatkan pengetahuan dan motivasi untuk mengelola sampah organik hasil limbah rumah tangga hingga 50% (Setiawan & Lestari, 2022).…”
