Background

• Public life in handicrafts field is growing. One of the finishing process of souvenir products / handicraft such as bracelets, necklaces, rings, household appliances, automotive is the electroplating process.

• The advantages that can be obtained from the electroplating process are resistant to corrosion and products becomes bright / glossy. Hower, the process will generates solid waste, liquid and gas emissions.

Liquid waste contains of dissolved metals and more hazardous compounds. In addition this waste con pollure the environment and can be harmful to health.

• In order to not pollute the environment and damage the health the metal waste to be discharged into the environment content of have to be less than maximum content of limit effluent quality standards for the production metallic coatings by the environment minister decision KEP-51 / MENLH / 10/1995.

• With parameters (total suspended solids) TSS (60 mg / L), cyanide (12.05 mg / L), total metal (8.0 mg / L), copper (Cu) (3.0 mg / L), nickel (Ni ) (5.0 mg / L) and pH (6.0 to 9.0).

Research Objectives

• To determine the rate of decline after electroplating wastes mixed with the ulva were treated with whiting.

• To find which of the ulva biosorben and ulva is with whiting treatments has the ability to reduce levels of electroplating waste better.

problem definition

the need for problem definition. Limitations are as follows :

• Time required to filter waste and biosorben until mixture becomes a liquid that is ready to be tested is assumed equal.

• Raw materials biosorben by whiting treatments used is to 1 kilograms Ulva is mixed by 100 grams lime to first sample of 250 grams lime to 300 grams sample of a second and third samples by lime to was added 2 liters of water to each treatment.

• To 100 ml of electroplating waste mixed by 15 grams biosorben powder in 30 minutes.

benefits research

• To provide input for industries engaged in the electroplating (plating) metal to utilize seaweed as biosorben absorption of heavy metals.

• Reducing rate of spread waste in the environment.

• Utilizing waste as waste neutralizer.

• Additionally the experience and science that is very meaningful to researchers in filtering waste.

• Ni content in electroplating waste is much as 162 mg / L exceeds quality standards of waste electroplating nickel (Ni) is equal to 5.0 mg / L.

• To biosorben ulva without treatments whiting on the test results leaving Ni content of 1.46 mg / L.

• Biosorben ulva by treatments whiting in the test results, leaving the Ni concentration of 3.28 mg / L, 5.46 mg / L and 5.07 mg / L respectively to treatments ulva whiting 100 grams, 250 grams whiting and 300 grams whiting.

• Seen to simply in biosorben ulva and ulva 100 grams by whiting successful treatments leaves consecutive Ni content of 1.46 mg / L and 3.28 mg / L were has below electroplatig wastewater quality standards.

Decreased levels of Ni

• Test data will be presented in the form of a table chart. As a percentage reduction of waste levels calculated by the formula :

• Beosorben ulva without whiting successfully reduced until 99% Ni content. Because the levels were absorbed is smaller waste compared to using ulva without lime, it percentage decrease in Ni content biosorben ulva by treatments whiting are also is smaller in the amount of 97.9%, 96.6% and 96.8% respectively - each ulva (ulva + whiting 100 g), (Ulva + whiting 250 grams) and, (Ulva + whiting 300 grams).

• Biosorben ulva were are treated by whiting has the ability to absorb elements Ni lower than biosorben ulva without whiting so the best biosorben is ulva without mixture whiting.

• Concentration whiting in biosorben do not have a clear relationship to the ability to absorb Ni where the higher levels of whiting, the remaining waste levels fluktrasi.

• ulva lactuca seaweed species have a high enough ability in to adsorb heavy metals because on in algae are functional groups were can do by binding of metal ions. The functional groupsmainly carboxyl groups, hydroxyl, amine, sulfudril, imadazol, sulfate and sulfonate present in the cytoplasm of cell wall (Sinly Evan Son, 2006).

• In this study biosorben ulva lactuca are treated by whiting to absorb the levels of nickel on in electroplating waste but mix whiting have been inhibiting the absorption of Ni content.

• This is because whiting has covered the pores of biosorben ulva lactuca and when filtering by filter paper equip guide produce limestone deposits in filtering results It is most likely were cause becoming an absorption of nickel levels slightly.

Conclusion

• Based on the research conducted, it can be concluded as follows:

• Ni content in electroplating wastewater was 162 mg / L decreased 99% to 1.46 mg / L by using biosorben ulva.

• Concentration levels of whiting by biosorben have no significant correlation to decrease levels of Ni and has less ability to reduce levels of Ni than ulva without treatments.

• Biosorben ulva and ulva by 100 grams whiting could reduce levels under limit of Ni until quality standards. The best Biosorben is ulva without a treatments because it has ability to reduce the higher Ni and do not need other treatments.

Suggestion

• More research needs to be done to know the metal elements were has not tested as: chromium element (Cr), lead (Pb), copper (Cu), zinc (Zn), cyanide (Cn) and so on.

• Is necessary to determine the concentration of whiting more precise so as not to close off pores of ulva lactuca.
