Abstract

The increase of waste production has been affecting global warming, triggering the climate change. The right cultivation based on the environment and its existence could expectantly turn into a clean, sanitary and comfortable environment. Moreover, the appropriate waste could generate additional values that would increase income. Inedible factory waste of tempeh could be utilized for organic liquid fertilizer. Based on its premise, author has done research titled "Nutrient Testing of Organic Liquid Fertilizer in Tempeh Factory". The analysis done in a lab of Central Plantation Services resulted that N total 537 mg/Kg, P2O5 442 mg/Kg, K2O 2700 mg/Kg, Mg 175 mg/Kg, Cu 0,32 mg/Kg, Zn 0,95 mg/Kg, C-Organic 3800 mg/Kg pH H2O 4,88 and C/N Ratio 7,08Introduction.
