Abstract

Background: Nitrates (NO3-) are natural inorganic ions, which are part of the nitrogen cycle. If nitrate content in water exceeds 50 mg / L, it can cause yellowish taste, odor, and water, cause stains on clothing and increase bacterial proliferation. Therefore, it is necessary to decrease the nitrate concentration using teak sawdust containing extractively lignin which can decrease the nitrate level. Research Objectives: This study aims to examine the decrease in NO3-concentration using teak sawdust with concentration variation and soaking time. Method: The research was conducted in Chemical Laboratory of Faculty of Nursing and Health of Muhammadiyah University of Semarang. The study was conducted in February 2017-August 2017. The samples of the research using NO3-50 ppm solution were immersed using sawdust sawdust with concentration variation (3% w / v; 6% w / v; 9% w / v; 12% b / v) and soaking time (3 hours, 6 hours, 9 hours, 12 hours). Results and Conclusions: The results showed that the highest percentage reduction of nitrate content was 33.815% obtained in the addition of sawdust teak wood 3% w / v with 12 hours of soaking time. The highest adsorption capacity of teak sawdust was highest with the addition of teak sawdust 3% w / v and 12 hours of soaking time of 0.6324 mg / g. The highest percentage reduction (NO3-) of 33.815% was obtained from the addition of sawdust teakwood 3 % b / v for 12 hours. Keywords: NO3-, sawdust teak, Variation Concentration, adsorption capacity.
