Abstract

Air limbah deterjen umumnya mengandung senyawa aktif surfaktan anionik. Pembuangan limbah ini langsung ke lingkungan dapat mengganggu biota perairan dan menurunan kualitas tanah serta memiliki efek karsinogenik jika manusia terpapar dalam jangka waktu yang lama. Tujuan penelitian ini untuk menentukan dosis biokoagulan Moringa Oliefera L. (MO) yang efektif untuk menurunkan kadar surfaktan (LAS) pada air limbah deterjen dan mengetahui pengaruh jenis air (air koagulasi, air limbah deterjen dan air keran) terhadap perkecambahan Vigna Radiata.  Hasil analisis diperoleh dosis optimum dengan penambahan biokoagulan biji kelor 2000 mg/L dengan persentase penyisihan LAS sebesar 96%. Selain itu, uji pengaruh jenis air terhadap perkecambahan  kacang hijau diperoleh tinggi batang dan luas daun yang disiram air hasil koagulasi (25,9 cm  dan 14,1 cm2) lebih baik dibandingkan dengan air keran (24,3 cm dan 10,99 cm2) dan air deterjen (24,6 cm dan 9,6 cm2).  Namun  hasil uji Anova menunjukkan dampak konsentrasi LAS pada air tidak ada perbedaan nyata. Kata Kunci: koagulan, biji kelor, air limbah deterjen, LAS   ABSTRACT Removal of Surfactant Anionik From Detergent Wastewater By Biocoagulant Moringa Oleifera Seeds Detergent wastewater commonly have surfaktan anionic as active agent. Disposal of this wastewater directly into the environment can disrupt aquatic biota and reduce soil quality as well as have carcinogenic effects if humans are exposed to it for a long period of time. The aim of this research is determined optimum dosages Moringa oleifera L. (MO) as biocoagulant to remove LAS from laundry wastewater and evaluate the effect of coagulation water, detergent wastewater and tap water to Vigna radiata germination. The result show that optimum dosages of Moringa oleifera L. is 2000 mg/L which could remove 96% of LAS in sample. Moreover, the study of the influence water to Vigna radiata germination show the lenght of steam and leaf by coagulation water ((25,9 cm and 14,1 cm2) better than coagulation water (24,3 cm and 10,99 cm2) and tap water (24,6 cm and 9,6 cm2). However, the result anova test show that the effect of LAS concentration in water is not significant.   Keyword: coagulant, Moringa oleifera, detergent wastewater, LAS

Abstract

It has been conducted a research, which it aims to know the antibacterial and biodegradation nature of EDTA-Ag and chitosan immobilized silica composite plastics. Silica used was from rice hull processing products. Chitoson used was 0.3 and 0.7 g. Antibacterial assay was conducted over Staphylococcus aureusandEscherichia coli bacteria. the result obtained showed that the biggest inhibitory is at variation of chitosan 0.7 g, which over Staphylococcus aureusbacteria is 15.6 mm and Escherichia colibacteria is 16,7 mm. While, in biodegradation assay, the highest degradation percentage is at chitosan variation 0.3 g, namely 32.17%.

Abstract

It has been done a study of mono acyl glycerol compound synthesis through partial transesterification of castor oil (Ricinus communis L.) using KOH as catalyst. The product of mono acyl glycerol obtained is 45.4 % with the ratio between castor oil triglyceride and methanol 1:2 at 35 0C temperature with the amount of catalyst 0.5 % (b/b) from the reactant total weight and the reaction time 30 minutes. In this research, it was done a compound characterization using, TLC, FTIR and LC MS to prove the success of targeting compound has been synthesized.

Abstract

The use of pumice and sand as a media in Constructed wetland (CW) system to reduce anionic surfactant has been carried out. This research aimed to investigation the efficiency of pumice and sand in CW system with and without plant (cymbopogon citrates) for CW anionic surfactant removal. There were six variation of CW treatments based on percentage pumice amended in the sand media. The anionic surfactant were analysed using UV-VIS spectrophotometry with metilen blue methods. Results of the analysis on oneway anova showed that the efficiency removal of anionic surfactant in inflow and outflow is significant different, on the variation of media of pumice 10% and sand 90% (CW B) reduced anionic surfactant levels efficiently from an average of 0,481 ppm ppm to 0,188 ppm with a decrease in percentage value of 60,91%.
