Abstract

Ecoenzyme is a complex organic solution that can be an alternative for environmental management. Ecoenzym is made by fermenting water spinach, chinese cabbage, mango, papaya, with palm sugar or granulated sugar and water in plastic bottles of 1500mL for 3 months. Ecoenzyme solution was analyzed for aroma quality, color, pH, volume and alcohol content. Ecoenzyme residues (BRE), effective microorganisms (BEM) and without bioactivator (TBP) were tested for the ability to decompose organic waste aerobically in plastic buckets. All treatments produced an ecoenzyme solution with a strong acid aroma, light brown to reddish brown in color, pH ranging from 3.1-.3.4, volume ranging from 740-780mL and contained alcohol ranging fom 4.1-4.8%. The lowest volume of ecoenzyme solution was 740mL in ECO2 and the highest was 780mL in ECO6. The lowest alcohol content is 4.1% in ECO3 and the highest is 4.8% in ECO5. Residual ecoenzymes (BRE), effective microorganisms (BEM) and without bioactivator (TBP) are able to decompose organic waste with the results of pH, temperature, humidity, total N, P2O5 and K2O that meet the Indonesian national standard (SNI) for composting. The composting pH value ranging from 6.4-7.5, temperature ranging from 27-36oC, humidity ranging from 66-81%, total N ranging from 0.68-0.80%, P2O5 ranging fom 0.49-0.54%, and K2O ranging from 0.75-.0.90%. This study concludes that the use of mango and papaya waste and palm sugar produces an ecoenzyme solution with the highest alcohol content and potential ecoenzyme residues as a bioactivator for organic waste composting

Abstract

ABSTRACT. Due to their phytochemical constituents, Dewa leaves (Gynura japonica (Thunb.) Juel.) are often used in traditional medicinal herbs. However, in vitro and in vivo of antioxidative and anti-aging studies of Dewa leaves on yeast as a eukaryotic cell model have not been widely carried out. This study aims to determine the antioxidant, anti-aging, and antibacterial activities derived from G. japonica leaves extract. Extraction was conducted using 70% and 96% ethanol solvents, total phenolic content (TPC) was assayed using Folin-Ciocalteu method, flavonoid contents (TFC) was assayed using aluminum chloride method, antioxidant activity was tested using DPPH (1,1-diphenyl-2-picrylhydrazyl) and ABTS (2,2-azinobis-3-Ethylbenzothiazoline)-6-sulfonic acid) radicals. Subsequently, an anti-aging activity test was performed on the yeast Saccharomyces cerevisiae as a model organism following antibacterial activity. The antibacterial activity test was carried out using well diffusion agar, and the Minimal Inhibitory Concentration (MIC) was determined using the microplate method. We obtained that G. japonica leaves extracted from 70% and 96% methanol solvents, have TPC of 13.14 and 22.11 mg GAE/gr extract, and TFC of 8.04 and 14.09 mg QE/gr extract, respectively. As for DPPH and ABTS antioxidant activity, D70 showed the best activity with IC50 values of 1411.36±56.35 µg/mL and 2516.10±18.77 µg/mL, respectively. The anti-aging test showed that both 70% and 96% ethanol extracts were able to maintain the yeast cell viability under H2O2 oxidative stress. Further, 70% and 96% ethanol extract also showed antibacterial activity at the best value against Staphylococcus aureus with a MIC value of 390.62 µg/mL, it means that Gynura leaves extract has a potency as antibacterial agent. The results of this study indicate that the ethanol extract of G. japonica leaves can be developed for further investigation as an antioxidant and antibacterial therapeutic agent.

Abstract

Boron neutron capture therapy (BNCT) is a selective targeting cancer therapy method which is by radiating epithermal neutron beams to a tumor which has been injected by boron-10 compound. The implementation of this method requires 2 (two) key elements, namely the boron-10 compound and the irradiating neutron beam of epithermal energy level. The neutron source used in this research was 13 MeV 1mA cyclotrons which have been developed by Indonesia National Nuclear Energy Agency. This paper was preoccupied in beam shaping assembly (BSA) target system. BSA target system is used to convert the proton produced by cyclotron into neutron. IAEA generated a recommendation for BNCT neutron beam quality, one of them was epithermal neutron flux which is higher than 109
