Abstract

Bengkuang (Pachyrrhizus erosus Urb.) has been known as natural insecticide due to the existence of toxic compound called rotenone. There are some publications on the usage of the P. erosus as pesticide but the affects of seed extract of P. erosus to the larvae of Aedes aegypti based on LC50 and their sub-lethal effects has been unstudied. Accordingly, the research questions were (1) what is LC50 value of the seed extracts? and (2) how does the sub-lethal effect of the seed extract to the larvae derived from their physical morphology and physiology?. The research was done by experimental study using completely random design of five different concentrations (i.e. 0,1%, 0,2%, 3%, 0,4%, 0,5 & 0% as a control) with four replication. Seed extraction followed Harborne (1987). Observation and calculation on the mortality of the larvae were done each six hours in 24 hours. Statistical analyses was done using One Way Anova and LSD test. The result showed that the concentration of the seed extract has significant influence to the mortality of the larvae of A. aegeypti (instar III) with LC50 value on 0,18%. Also, the seed extract caused morphological damages on some parts of the larval body such as head (chepal), chest (thorax), stomach (abdomen), anal gill and loss of hairs on the side of the body. The dead larvae always could be found on the bottom of substrate. The movement of the larvae tend to deliberate after six hours up to 24 hours. Based on the research result, we assume that the seed extract of P. erosus has a potential role as a natural insecticide especially on the larvae of Aedes aegypty (instar III).

Abstract

Iron sand is one of natural materials that has been widely explored and so far is  only used  as building materials. This research provides solutions to increase the economic values of iron sand, by preparing ferrogel from iron sand. The purpose of this research is to prepare Fe3O4 nanoparticles-based-ferrogel from synthetic Fe3O4  prepared from iron sand. The iron sand was obtained from north coast of Central Java. The preparation of synthetic Fe3O4 produced nanoparticles having a size of 82,42 – 110,9 nm. The characterization using XRD indicated that Fe2O4 content in the iron sand was 30%, and increased to 76% in the synthetic materials. In addition, the synthetic materials has additional phase of Al0.95 Ga0.05. The ferrogel was prepared by mixing the synthetic materials with PVA (Polyphinyl alcohol). The ferrogel was characterized for its magnetoelasticity properties so that it can be used for artificial muscles. The results of magneto- elasticity ferrogel characterization showed that the higher the concentration of Fe3O4 filler in PVA matrix, the higher the deviation and elongation. However,  the impurity of Al0.95 Ga0.05 in the ferrogel seemed to cause its magnetoelasticity to be less than optimum.

Abstract

Oxidative stress induced by the radicals have been known to affect the occurrence of various degenerative disease. As the search for natural antioxidant compounds had been studied the isolation and identification of antioxidant compounds in fern stems (Alsophila glauca J.Sm) using DPPH method (1,1-diphenyl 2-picrylhydrazyl). Fern stem extraction was done by maceration with wasbenzen and metanol. Extracts was obtained by evaporating the wasbenzen solvent with a rotavapor. Material was re-macerated with methanol after all wasbenzen evaporation. The same way was done on  wasbenzen to obtain the metanol extract. These extracts were tested for antioxidant activity using DPPH method with TLC. Active extract was partitioned in 80% methanol. Extracts both soluble and insoluble in methanol 80% were tested their antioxidant activity using DPPH method (TLC). Active extract was fractionated in vacuum liquid chromatography using a mobile phase with different polarity gradient and different concentrations (wasbenzen:chloroform). Active  fraction  was  isolated  by  preparative TLC method and purity of compounds obtained was tested by TLC. Antioxidant activity of isolates obtained were tested by DPPH method using spectrophotometry. Compounds known to had antioxidant activity as radical catcher with IC50 178.4 µg/ml.
