Abstract

This research discusses about broiler chickens which are given turmeric herbs by giving through feed and drinking water. The chickens used were 96 Cobb DOC strains, 8 for each experimental unit. The study used 3 treatment and 4 repeat. The treatment is: T0 = basal feed, T1 = basal feed + 2% turmeric from the amount of feed consumption and T2 = basal feed + 2% turmeric from the amount of drinking water consumption. The parameters discussed in this study are the performance of broilers consisting of feed consumption, drinking water consumption, body weight gain, final body weight, feed conversion, mortality and income over feed and chicken costs. Feed consumption, drinking water consumption, body weight gain, final body weight, feed conversion and mortality are not supported by significant maintenance (P> 0.05). The highest income from feed and chicken costs in T2 training is Rp. 11,582. The conclusion of this research is the application of turmeric is more optimal if applied through drinking water at a level of 2%.

Abstract

Chrome by product comes not only from elektroplating industry but also textile industry, leather tanning and laboratory waste. Looking at its existence and hazard, chrome by product has to further handled in order not to give negative effects to living creatures and environment. To avoid polluting the environment, the waste has to be processed first by lowering its content. One of the methods to reduce the content of the heavy metal is adsorption by using active bentonite as adsorbent. The purpose of this research is to find out the ability of active bentonite in reducting the content of chrome by product in waste. The procedure in this research consists of bentonite preparation, bentonite activation, content of chrome analysis in the raw material (waste water electroplating). The optimum treatment for the adsorption was at the mass of 25 gram stirred at 597 rpm with the contact time of 4 hours. Adsorption at the mass 25 grams could reduce chrome content from the initial chrome content waste water 394.59 mg/L to 194.34 mg/L with the reduction of chrome  of 49.48%
