Abstract

This study aims to determine the effect of the use of TiO2/Zeolite on reducing concentrations of nitrate, nitrite, ammonia, phosphate, BOD, COD and pH in agricultural wastewater by photolysis. In this study, sample analysis was carried out using UV-Vis spectrophotometer and FTIR and for the characterization of TiO2/Zeolite catalysts using FTIR, XRD and SEM. In agricultural wastewater samples, the initial concentration of nitrate was 11,409 mg/L, nitrite was 0,424 mg/L, ammonia was 5,075 mg/L and phosphate was 5,364 mg/L. The most optimum decrease in concentration for nitrate, nitrite, ammonia and phosphate, respectively, was 4,332 mg/L with an irradiation time of 90 minutes; 0,118 mg/L with an irradiation time of 75 minutes; 0.395 mg/L with an irradiation time of 90 minutes and 1,207 mg/L with an irradiation time of 60 minutes on the addition of TiO2/Zeolite as much as 0.8 grams for the determination of nitrate and phosphate while for nitrite and ammonia as much as 0.6 grams. Prior to the degradation, the BOD value was 62,4 mg/L and the COD value was 107,07 mg/L. Meanwhile, after degradation, the BOD value decreased to 5,92 mg/L and COD to 35 mg/L. The results of the analysis using FTIR on agricultural wastewater show that there is no significant shift in wave number before and after degradation. The characterization of TiO2/Zeolite catalyst using FTIR, XRD and SEM did not show significant changes before and after the degradation process was carried out which indicated that TiO2/zeolite could be applied in degrading agricultural wastewater.

Abstract

The use of feed in fish farming is often inefficient because fish only partially consume the feed spread in ponds, so it becomes waste for the aquatic environment and, even worse, will trigger new diseases. The Department of Chemistry's of Universitas Andalas team was trying to overcome this problem by increasing the efficiency of fish feed. For the feed to work optimally and produce good quality fish weight, it is necessary to modify the nutrition of the fish feed, one of which is by adding probiotics through a fermentation process. The method used in this activity includes training, mentoring, and demonstration plots in feed fermentation and counselling regarding the right time to feed. This activity targets fish farmers in the Koto Luar area, Pauh District, Padang, with a fish culturing group, "Family Sepakat", as the partner. Feed fermentation was carried out with probiotic starters such as Bacillus sp., saccharomyces cerevisiae, L. fermentum, L. plantarum, and W. paramesenteroides. This activity improved catfish growth, and the death rate was lower than in catfish farming without feed fermentation treatment.
