Opis:
This study aims to optimize the removal of total suspended solids (TSS) in pump water from fish flour factories through electrocoagulation technology and to determine the effects of the main operation parameters. Pump water has high conductivity (40.1 mS), due to the presence of dissolved salts and contains high concentration of organic substances (12,360 mg/L of TSS and 520 mg/L of fats). In this study, pump water was treated in an electrocoagulation reactor with aluminum electrodes using Response Surface Methodology with a 3k factorial design based on two factors, current intensity (I) of 8-13 A and treatment time (t) of 20-40 minutes. The percentage of TSS removed from the water was used as the response variable. The results revealed that I and t significantly (p < 0.05) influenced the process. In accordance, the optimal operational parameters for TSS removal were I = 13 A and t = 30 minutes. Using these conditions, TSS removal efficiency of 99.9% was achieved. The sewage sludge generated with these optimal process conditions indicated 19.3% of ash content, 6.2% of salt, 1.7% of aluminum, 0.3% of iron, 0.4% of potassium, 256 ppm of zinc, and 2.1% of phosphorus. Hence, the results of this study affirm that electrocoagulation can be considered as a solution for marine pollution caused by fishing industries.

Opis:
Feed greatly affects the growth and health of fish, however it also functions to increase the value of the color intensity when specific additional ingredients are added. One of the important ingredients, marigold-meal is one of the natural carotenoid sources. This research aims to determine the optimum concentration of marigold-meal in the artificial feed to increase the intensity color of koi fish, specifically the kohaku strain. The method used was an experimental Completely Randomized Design, consisting of five treatments and four replications. Parameters observed were color intensities analyzed using Kruskal-Wallis analysis, if there were significant differences, Z test would be performed. Research results were the color intensity enhancement of koi fish tails and head until the 40th day showed the highest value in the treatment concentration of 0.0% marigold-meal (positive control) with an average score of 8.00 and 10.00. This value was not different from the treatment concentration of 2.0% marigold-meal and concentration 1.5% marigold-meal. However, this value was not significantly different from concentration of 1.5% marigold-meal. The lowest average score on the tail and head was treatment concentration of 0.0% marigold-meal (negative control). The optimum concentration of the addition of marigold-meal resulting the best color intensity increase was in 1.5% concentration of marigold-meal with the color intensity value of 5.97 in the tail and 6.50 in the head of koi fish Kohaku strain.
