Abstract

Cassava is the third staple food often used by people to make a variety of products. Carbohydrates from cassava also contains toxic compound such as cyanide which can inhibit the action of respiratory enzymes. Cyanide in cassava can be removed by boiling or frying process. The aim of research was to find out the cyanide level differences between boiled cassava and fried cassava. This type of research was experiment, with design of comparative studies approach. Cyanide levels were examined in 10 samples with 2 treatments using Argentometry Volhard titration method. The result showed the average of cyanide levels in boiled cassava was 0.772 ppm and in fried cassava was 1.069 ppm. The percentage of cyanide levels reduction in boiled cassava was 28,78%, while for the fried cassava was 0%. The statistical test obtained the value of p

Abstract

Abstract: The levels of Biological Oxygen Demand (BOD) in the waste can be reduced by utilizing water plants such as velvetleaf (Limnocharis flava) as phytoremediation. This study aims to determine the influence of the many clumps Limnocharis flava to decreased levels of effluent BOD rubber industry with a variety clump Limnocharis flava much as 1, 2, 3, 4, and 5 clumps and clumps Limnocharis flava know the number of the most influential in lowering levels of BOD. This type of research is true experimental design with one group pretest-posttest. The research material was Limnocharis flava. The result showed the levels of initial BOD rubber waste amounted to 299.5 mg / l, decreased levels of BOD of waste rubber after being treated with Limnocharis flava with a variety of clumps. Decreased levels of BOD rubber waste for each successive treatment ranging from 1, 2, 3, 4, and 5 clumps genjer ie 13.65%, 14, 52%, 15.6%, 20.94%, and 29.05%. Based on test results obtained linear regression for each treatment their effect on levels of BOD using genjer rubber waste. Treatment using Limnocharis flava much as 5 clump results BOD levels decrease the total of up to 29.05%. This value has not met the standard the maximum allowable levels of BOD. Need soaking clumps Limnocharis flava more stout and longer so that the rubber waste reduction in BOD levels in accordance with the quality standards required.

Abstract

Dracontomelon dao (Blanco) Merr. & Rofe is one of the medicinal plants for the community. This study aims to analyze the ethanol extract of Sengkuang (Dracontomelon dao (Blanco) Merr. & Rofe) using the LC-HRMS Phytochemical Test and determine its antibacterial activity. Leaf Dracontomelon dao (Blanco) Merr. & Rofe originates from Hulu Sungai Utara, South Kalimantan, Indonesia, macerated with 96% ethanol. Antibacterial test by diffusion was carried out using the well method. LC-HRMS (Liquid Chromatography - High-Resolution Mass Spectrometry) test using the Instrument Thermo Scientific™ Dionex™ Ultimate 3000 RSLCnano UHPLC coupled with Thermo Scientific™ Q Exactive™ High-Resolution Mass Spectrometer. The content of chemical compounds from the ethanol extract, namely flavonoids 125.5 ± 0.433 mgEQ/g, alkaloids (%) 33.945 ± 0.781, saponins (%) 33.093 ± 0.755, tannins (mg/ml) 0.069 ± 0.003, the highest content was triterpenoids 669.8 ± 2,000(mg/ml). The best inhibition of E coli growth with the largest inhibition zone was 24 mm at a 500 mg/ml concentration. The active compounds contained in the leaves of Dracontomelon dao (Blanco) Merr. & Rolfe are quercetin-3β-D-glucoside, anacardic acid, D-glucosamine, azelaic acid, choline, astragalin, quercetin, luteolin, syringic acid. The active ingredient of the ethanol extract of Sengkuang (Dracontomelon dao (Blanco) Merr. & Rofe) has the potential as an antibacterial and anti-inflammatory that can be added to pharmaceutical preparations.
