Abstract

Constructed wetlands are a promising solution technology to effectively treat domestic wastewater in developing countries at low cost. This paper reports the findings of the effectiveness of sand planted with Thypa latifolia with variation of the length of outflow measured from the bottom of the media in removing BOD5, COD, and suspended solids. The experimental design consisted of 12 vertical flow (VF) mesocosms. There were 3 treatments and one control based on the with variation of the length of outflow measured from the bottom of the media (7, 14, and 21 cm).  During the five months, the mesocosms were loaded with syntethic wastewater. The influent had a 2-day hydraulic retention time. Samples were monitored for BOD5, COD and TSS. The results showed the concetration of BOD5, COD and TSS reduced significantly after the wastewater were treated with constructed wetland systems.  The trend showed that the constructed wetland systems planted with Thypa latifolia had a better performance in comparison with the control. There were no significant differences of BOD5 COD, and suspended solidoutflow among  7, 14 and 21  of constructed wetland systems. This indicated that the length of outflow measured from the bottom of the media did not influence the performance of constructed wetland systems in removing BOD5, COD and TSS

Abstract

Determination of total phenolic, total flavonoid, and antioxidant capacity of ethanolic extract and fractions from red ginger (Zingiber officinale var. Rubrum) has been done. Red gingers contain the highest oleoresins among other ginger varieties. Oleoresins are component that had the most responsibility for pharmacological effect of red ginger, one of them is as antioxidant. Phenolic and flavonoid are highly contributing to the antioxidant effect of red ginger. The aim of this research is to determine the antioxidant capacity of extract and fractions of red ginger, and to investigate the correlation between antioxidant capacity with both total phenolic and total flavonoid. Ethanolic extracts are fractinationed with n-hexane, chloroform, ethyl acetate, n-butanol, and methanol solvent. Antioxidant capacity, total phenolic, and total flavonoid of all the samples are measured. Highest antioxidant capacity, total phenolic, and total flavonoid obtained from ethyl acetate fraction with TEAC 2143.9 ± 0.9 µmol/g (CUPRAC) and 4526.4 ± 3.0 (DPPH), GAE 229.9 ± 1.3 mg/g, and QE 46,6 ± 1,8 mg/g. One way ANOVA and post hoc analysis show significant result with p value <0,01. Pearson correlation shows high positive correlation.

Abstract

Indonesia is an aquatic country with potential biodiversity. One of the potential biodiversity is microalgae. Microalgae potential to be developed as a functional food with the characteristics of its fatty acids. The most fatty acids found in diatoms are myristic acid, palmitic acid, DHA and EPA. One of marine microalgae contain lot of fatty acids is diatom Navicula salinicola. This study was aim to analyze fatty acid composition of marine microalgae Navicula salinicola. Navicula salinicola was cultivated in Guillard medium with 2.5; 5; and 7.5 % of nitrogen composition and cultivated for 11 days. Dry biomass obtained from harvesting was used for the extraction. Extraction of lipid from microalgae used Bligh & Dyer method with 9,9%; 14.5%, and 17.5% of oil yield. Result of GC-FID analysis that were 6 types of fatty acids that identified are palmitic acid, myristic acid, pentadecanoic acid, stearic acid, palmitoleic acid and eicosapentanoic acid, EPA. The highest fatty acid was palmitic acid with fatty acids percentage were 64.04%; 65.03%; and 53.55% respectively.

Abstract

The physicochemical propertis of forest honey (Apis dorsata) become one of the supporting qualities of honey. Good honey can be viewed from the quality of honey which refers to the Indonesian National Standard (SNI). Therefore, this research aims to determine the physicochemical properties of forest honey from the village of Bonto Manurung, Maros district, Tompobulu village, Pangkep district and Paranglompoa village, Gowa district in accordance with the SNI. The results showed that the best physicochemical properties of honey were from the village of Bonto Manurung, Gowa district which had a moisture content of 19.19 %b/b, ash content of 0.045 %b/b, viscosity of 14.82 poise , acidity is 42.43 mL N NaOH/kg, reducing sugar is 69 %b/b and HMF levels are 2.99 mg/kg. As for the analysis of metallic impurities, all samples examined forest honey is not contaminated by metals arsenic (As), cadmium (Cd) and lead (Pb).

Abstract

Synthesis and preparation of creatinine sensor material by molecularly imprinted method using N,N'-Methylenebisacrylamide (MBAA) and 2-Acrylamido-2-methyl-1-propanesulfonic acid (AMPSA) as precursors, on nylon membrane had been conducted. The precursor i.e. MBAA and AMPSA is used as cross-linker monomer, and functional monomer respectively, with the creatinine as template.  The performance of creatinine sensor material been studied by instrument response (resistance) pattern analysis to concentration of creatinine.  The result of FTIR spectra and SEM photograph, indicated the formation of molecularly imprinted polymer (MIP) on nylon membrane. Logarithmic pattern is appears as instrument response to concentration change of creatinine. Linear correlation of instrument response and creatinine concentration is observed at concentration ranges 1 to 5 ppm of creatinine. Comparative studies show that performance of nylon coated membrane is better than non-coated membrane. Linearity, limit detection, and limit quantification value of coated membrane is 0.9592; 1.2066 ppm; and 4.0221 ppm respectively. On the other hand for non-coated membrane, linearity, limit detection, and limit quantification value obtainedis 0.8799; 2.1607 ppm and 7.2044 ppm respectively.

Abstract

Salmonella typhi (S. typhi) infection is a zoonotic infection and known as salmonellosis. In the human body, salmonellosis causes an increase in high body temperature or known as typhoid fever that cause high morbidity and mortality in developing countries, especially Indonesia. It was found that out of 22 million cases of typhoid fever, 200 thousand of them ended in death. S. typhi often contaminates food that was consumed raw or not perfectly cooked, for example meat, eggs, dairy products, fruits and vegetables. The conventional method for detecting these bacteria is culture method which time consuming and need BSL 2  facilities. PCR was one of DNA based detection method that could overcome the culture method weakness. In this study conducted detection of Salmonella bacteria in raw vegetables which are usually consumed as fresh by using nested PCR method. The detection procedures were sample preparation; bacterial DNA isolation; amplification by using two sets of primer, ST1-ST2 in first round PCR and ST3-ST4 in second round PCR; and the characterization by using agarose electrophoresis. The results indicated that two of nine raw vegetables, tomatos and cabbages have been contaminated with Salmonella. We conclude that nested PCR could detect Salmonella contamination in raw vegetables.

Abstract

The study aimed to determine the secondary metabolites contained in raw banana peel waste, and to test the inhibitory activity in bacteria. Banana skin waste is used namely; banana kepok (Musa acuminata x balbisiana), uli banana (Musa paradisiaca sapientum) and nangka banana (Musa sp L) extracted using distilled water with the dekok method. The phytochemicals and antibacterial activity were tested for Staphylococcus aureus (S. aureus) and Escherichia coli (E. coli). Phytochemical test results showed the three banana peel extracts contain the same compounds, namely alkaloids, flavonoids, saponins, tannins and phenols. Different content of kepok banana peel extract is triterpenoid compounds which are not possessed by uli banana peel extract or banana jackfruit extract. The higher the concentration of extract used, the greater the inhibitory power of the bacteria. Antibacterial test results showed that 25% concentration of uli banana peel had the best antibacterial inhibition on S. aureus bacteria compared with kepok banana peel extract and jackfruit banana could not inhibit the growth of E. coli bacteria.
