Uji Karakteristik Unsur Hara Pada Pupuk Organik Cair Hasil Limbah Sayuran Dengan Penambahan Em-4 Dan Zeolit

Abstract

Human’s increasing activity causes an immense increase in domestic waste. one form of domestic waste which could harm environment is vegetable waste. in this research, vegetables waste is used as based material of liquid compost. The process of producing liquid compost with vegetables waste as the base materials was using EM4 fermentation method as a starter and zeolite 80-100 mesh as the bind for soil nutrient in liquid compost. In the fermentation process, the researcher conducted 3 different behaviors in adding EM4 and Zeolite, in each 10 gr, 20 gr and 30 gr of EM4; and 40 gr, 60 gr and 80 gr of Zeolite. The fermentation process was conducted in 40 days. The liquid compost samples were analized for pH, C-Organic, N-total, P-total and K-total. The results showed that highest concentrate of soil nutrient was from the adding of 30 gr EM4 and 80 gr Zeolite in which the result was 0.27% C- organik, 0,07 % N-total, 0,04 % , P-Total dan 0,46 % K-Total.

Effect of vegetable waste and banana stump composition in casabo fertilizer on nitrogen and phosphorus concentration

“…The waste used in this study is chicken eggshell waste, vegetable waste, and banana stump, which are processed through the fermentation process. The fermentation process of liquid fertilizer is biologically decomposing organic matter [20]. The result of fermentation after filtering showed in Figure 2.…”

“…It is because, in the fermentation process by bacteria in EM-4, there is a change from carbohydrate compounds, cellulose, hemicellulose, wax, and fat to CO2 and water, which causes C-organic. The Corganic content in liquid organic fertilizer will increase if more bacteria are added [22]. From the lab test results, the nutrient nitrogen (N) value is 0.07%.…”

“…Phosphorus elements are less contained in vegetable waste. Generally, vegetables are part of the leaves and stems of plants [30]. Although the value of phosphorus in fertilizer is small, the presence of phosphorus is very beneficial for plants.…”

“…Vegetable waste is a nutrient source rich in nitrogen, so with more use of vegetable waste materials in this liquid organic fertilizer, the nitrogen element increases. The nitrogen content is smaller than the carbon content because bacteria use carbon elements as energy and nitrogen elements to build cell and bacterial structures [34]. The N content in P5 and P6 has a large value because the amount of vegetable waste influences it.…”

Kandungan Unsur Hara Pupuk Organik Cair Dengan Penambahan Limbah Cangkang Telur Ayam Broiler

“…Menurut Nitrogen merupakan salah satu kandungan nutrisi penting pada pupuk cair dari cangkang telur. Adanya kandungan nitrogen pada Pupuk Organik Cair (POC) dikarenakan adanya aktivitas bakteri yang berasal dari EM-4 (Syuhriatin & Juniawan, 2019). Berdasarkan hasil penelitian, nilai nitrogen tertinggi yaitu pada pupuk A yakni sebesar 0,09%.…”
