Supported liquid membrane (SLM) was prepared by reacting host material with carrier compounds. Carrier compound was Polyethylene Glycol-400 (PEG-400) that have been used with the variation of concentration 0, 2, 4, and 6%. The effect of its variations in SLM was characterized by FTIR and the performance was examined by transporting feed solution Pb(NO3)2 with variation 1, 5, 10, 15, and 25 ppm for 3 hours in pH 3. FTIR spectra depicted that the increasing concentration of PEG would arise the intensity of typical PEG’s functional groups such as -OH, C-O-C, and CH2-CH2 sp3. The optimum transport Pb(II) was achieved by SLM with 6% PEG. Variation of feed solution concentration showed the main effect in SLM activity. The higher of feed solution concentration would decrease of transport activity. The % extract and % recovery 1 ppm was higher than 25 ppm with 72,5% and 70,27% than 6,1% and 3,59%, respectively.

Malaria has been prevalent for a long time in tropical developing regions causing great morbidity and mortality. Among the malaria vectors, Anopheles vagus has been known as secondary malaria vector in East Java. Salivary glands of mosquitoes perform various functions for survival of the vectors and also conducive for blood feeding, harbouring of malaria parasites, and eventual parasite transmission. The salivary gland proteomes of An. vagus have not been carried out yet. The aim of our study was to identify and characterize the immunogenic proteins of salivary glands proteins of An. vagus. A proteomic approach combining one-dimensional electrophoresis (1DE) followed by western blot analysis using human sera from healthy people living in an endemic area (Kendal); liquid chromatography mass spectrometry (LC-MS/MS) and bioinformatic analysis was adopted to provide the first direct insight into identification and characterization of salivary proteins of An. vagus. Identification of immunogenic proteins using western blot analysis has revealed three immunogenic bands which had molecular weights of 69, 75 and 232 kDa. Among those proteins analysed by LC-MS/MS, there were alpha,1-4 glucan phosphorylase, putative myosin class I heavy chain which have the highest number of total spectrum count peptide. Other proteins like vitellogenin and heat shock protein 82 (Hsp82) were also identified. The majority of proteins were scrutinized marked for their role in metabolism, cytoskeleton protein and stress response. Keywords: Anopheles vagus, salivary gland, immunogenic, proteomics

Onion is one of lowland vegetables commodity that has been long cultivated intensively by farmers in Indonesia. Probolinggo is one of the regions which give considerable contribution of producing onion to the national needs. In an effort to increase production, onion farmers in Probolinggo mostly relies on external supply in the form of artificial chemicals (fertilizers and pesticides). However, the using of artificial chemicals can cause pollution and damage the environment. So that utilization of biological agents and organic fertilizers which are environmentally friendly can become other solutions to increase the yield of onion production. Based on this case, it is very important in efforts to increase production of onion by combining organic fertilizers to enrich the content of organic matter in the soil with biological agents in tackling pests attack. Based on the research results in application of combining organic fertilizers granules plus NEP and biological agents Heterorhabditis sp. in District Gending Probolinggo shows that : 1. reducing the population of pests Spodoptera exigua up to 72.260%. 2. improving onion plant growth more optimal. From the result, it shows that the combination of organic fertilizer granule plus biological agents and NEP Heterorhabditis sp. (P2A1) is more effective than the combination of the others.

STT (Spin Transfer Torque) can be referred to as a process of manipulation and control of spin current in the field of spintronics. When the material is ferromagnetic nanowire La0.7Sr0.3MnO3injected currents will move the domain wall with accompanying changes of spin currents. In mikromagnetik simulation shows that the application is capable of producing flow velocity or pressure of domain wall in the direction of electron flow. The domain wall pressure generating magnetization changes with increasing current density occurs. To that end, the simulation research was done in order to obtain the effect of the injection of electric current to the magnetization of the material. This phenomenon is simulated by modeling the material into the 3D geometry. The greater the current density is given the domain wall velocity or pressure on the nanowire faster so that the magnetization process is also faster. Changes in the velocity of the fastest domain wall is obtained when the material is injected with a current density as well as M-t get a graph showing oscillation pattern that is denser when the current is increased. Furthermore, the total energy analysis with variations in size diameter of 10 nm, 20 nm and 30 nm. The results show that with increasing diameter, total energy tends to increase. Keywords: spin transfer torque, La0.7Sr0.3MnO3, magnetisation, domain wall, ferromagnetic
