چکیده
Highlight ResearchWastewater in hybrid grouper culture should be maintain before resirculate and dispose to aquatic environment avoid eutrophication.Seaweed that is used for biofilter must observed its suitability, performance effectivity.Ulva sp. has the best effectiveness reduce nutrient wastewater of aquaculture by absorbing then stored into thallus.Ulva proven SGR adaptability culture.AbstractWastewater generated from needs managed improve water quality being recirculated, or discharged environment. Seaweed been proposed treatment technology marine fish farming. This study aimed at comparing which these species i.e. Ulva sp., Sargassum Gelidium Dictyota work absorb culture. research utilized seaweed as treatments controls with three replications using Completely Randomized Design. A statistical analysis was conducted investigate significant differences absorptions among various ANOVA least difference. Non-parametric tests namely Kruskal-Walis, Mann-Whitney, t-test were confidence interval 95%. The results revealed ability Nitrogen 80%, while able Phosphor 88% While highest absorbtion Total Kjeldahl (104%) phosphate (182%) thallus performed had growth rate (1.9% d-1) cultivation than other species.

A Strategic Mild Hybrid Technology for Reducing Pollution and Optimization of Fuel Sources
Many studies have been done on hybrid vehicles in the past few years. The full hybrid vehicles need a large number of batteries creating up to 300 (V) to meet the required voltage of electric motor. The size and weight of the batteries cause some problems. This research investigates the mild hybrid vehicle. This vehicle includes a small electric motor and a high power internal combustion engine...
