KANDUNGAN FORMALDEHIDA PADA LIMBAH CAIR PROSES PENYAMAKAN KULIT SARUNG TANGAN GOLF SNOW WHITE

EDDY PURNOMO1)


ABSTRACT

Snow white golf glove is made from sheep skin tanned by aldehyde groups of tanning agent. Golf glove Tanneries usually use formalin (formaldehyde 30%-35%) as the main tanning agent. Practically, the formalin uses are varied from 5.0%-7.0%. The objective of this research is to observe the formaldehyde content in tanning waste water. The simulation used the leather tanning of snow white golf glove from sheep skin. Formulation and tanning method applied are similar with those of the three different tanneries (A; B; C). The A formulae used technical formalin (30%) = 5.0 %; B formulae = 5.5 % and C formulae = 6.0 %. The research used waste liquid from tanning process by taking each 100 ml and tested the formaldehyde content. The quantity of formaldehyde in waste water can be measured by Schiff reagent and visible spectrophotometric. The analytical data statistics used one way ANOVA, CRD three treatments and five replications and then continued with the descriptive analysis. The result of the research shows that there was no significantly different content of formaldehyde in each tanning method. Formaldehyde content mean of tanning water waste in A method is = 8.62 g/L; B method = 8.51g/L and C method = 8.9 g/L. Total mean is 8.68 g/L. Nevertheless all of the three tanning methods still consist of formaldehyde in their waste water above the allowed threshold.
