Abstract
Food industrial sludge generally has agricultural values such as nitrogen, phosphorus, and potassium in quite high levels. Through laboratory test result, porang industrial sludge has a good agricultural content, but it still needs a nitrogen enhancement. In this study, feather meal (FM) was given as a source of organic N in three doses- 0grams (P0), 10grams (P1), and 25grams (P2). FM addition is expected to boost the sludge agricultural content so the plant can thrive until harvest time without additional fertilizer. The object of this study is pakcoy (Brassica rapa L. ssp. chinensis) and it aims to determine the effect of porang industrial sludge usage as a planting medium on plant growth and development. Laboratory scale observations were made on several parameters, including height, number of leaves, leaf area, fresh weight, and dry weight of plants. The results showed that each treatment for each parameter was significantly different, with the best plant height being P0, the largest number of leaves were P0 and P1, the largest leaf area was P0, the largest wet weight was P0, and the largest dry weight parameter is P0. Thus, the treatment with the best effect on the growth and development of pakcoy is P0.
