[APPLICATION OF LIQUID ORGANIC FERTILIZER FROM EGGSHELL AND TOFU DREGS ON PROMOTING GROWTH AND YIELD OF LETTUCE UNDER FLOATING RAFT HYDROPONIC SYSTEM]. Eggshell waste and tofu pulp contain nutrients that have the potential as plant fertilizers. The use of liquid organic fertilizer (LOF) from eggshells, and tofu dregs can be a source of nutrition in hydroponic cultivation at a relatively low price. The optimal growth of red lettuce plants requires a proper concentration of nutrients. This study aimed to examine the effect of the concentration of LOF from eggshells and tofu dregs that are most effective in increasing the growth and yield of red lettuce in floating raft cultivation systems. This research was conducted from December 2020 to February 2021 at the Kartini Experimental Garden, Faculty of Agriculture and Business, Satya Wacana Christian University. This study used a Randomized Complete Block Design with liquid organic fertilizer made from egg shells and tofu dregs with different concentrations and AB mix as a comparison. The treatment consists of five levels, namely AB mix, LOF 10 mL/L, LOF 20 mL/L, LOF 30 mL/L, and LOF 40 mL/L. Observation parameters include plant height, number of leaves, leaf area, root length, and fresh and dry weight of the plant. The results of the observations were analyzed using the analysis of variance (F test 5%). On average, the HSD Tukey test followed the treatment with a confidence interval of 5%. This study showed an influence on the treatment of eggshell LOF concentration and tofu dregs 20 mL/L resulting in the highest red lettuce with 9.15 leaves, root length 38.75 cm, header fresh weight 36.33 g and highest root fresh weight 16.22 g at LOF treatment 10 mL/L. These results have not matched the application of ABmix fertilizer, which reached the fresh weight of 74.79 g.

“…So that the ammonia level after processing is still below the quality standard. If the ammonia concentration is high, it can indicate organic matter contamination from domestic wastewater [22][23][24]. Sources of Ammonia are urine, feces, and the oxidation of organic matter by bacteria naturally [25].…”

One of the causes of water pollution is the presence of workshop activities. Gasoline residue from washing spare parts and washing hands after repairing and maintaining motor vehicles can harm the surrounding environment, namely water pollution. This study aims to determine the efficiency of reducing the levels of pH, BOD, COD, TSS, oil and grease, Ammonia, and total coliform in wastewater from Astra workshop operations using three treatment and treatment units in the piping section and to determine the design of wastewater treatment tanks for operation astra workshop. Based on the preliminary test results, the waste from Astra workshop activities had a pH content of 7.2, a BOD content of 2.9 mg/l, a COD content of 58 mg/l, a TSS content of 2.45 mg/l, an oil and fat content of 8.702 mg/l, the ammonia content was 0.027 mg/l. The total coliform content was 2000 MPN/ml. Of these values, there is one parameter that does not meet the quality standards according to the Decree of the Minister of Environment and Forestry No. 68 of 2016 concerning Domestic Waste Quality Standards, namely a pH concentration of 6-9, a maximum level of BOD of 30 mg/l, a maximum level of COD of 100 mg/l, a maximum level of TSS of 30 mg/l, a maximum concentration of oils and fats allowed 5 mg/l, maximum ammonia concentration of 10 mg/l, and maximum permitted total coliform content of 3000 MPN/ml. This workshop liquid waste treatment uses three treatment and treatment units in the piping section with one filtration media, which is carried out in duplicate to anticipate and minimize the possibility of errors that can occur during the process. Efficiency in reducing parameters in liquid waste from Astra workshop operations using filtration media and treatment in the piping section can reduce the pH concentration by -15.29%, from an initial concentration of 7.2 to 8.5, TSS by 59.18% from an initial concentration of 2.45 mg/l to 1 mg /l. BOD was 72.41% from an initial concentration of 2.9 mg/l to 0.8 mg/l. COD was 65.51% from an initial concentration of 58 mg/l to 20 mg/l. Fatty oil was 45.41% from an initial concentration of 8,702 mg/l to 4.75 mg/l. Ammonia by 48.14% from the initial concentration of 0.027 mg/l to 0.014 mg/l, and Total Coliform by 100% from 2000 MPN/ml to 0 MPN/ml.

“…The content of organic compounds that are quite a lot causes this waste to have the potential to provide nutrients for plants that can be used as organic liquid fertilizer products [4]. Using tofu and tempe industrial waste as organic fertilizer is hoped to become an alternative fertilizer to increase soil fertility and crop production [5][6][7][8][9][10].…”
