Daya Antibakteri Estrak Kulit Dan Biji Buah Pulasan (Nephelium Mutabile) Terhadap Staphylococcus Aureus Dan Escherichia Coli Secara in Vitro

Traditional medicine from drug crop has more than a pharmacological effect so that its use should be acurate and correct. The mistake in traditional medicine USAge and or drug crop can be dangerous for health. Therefore, it is required a complete scientific information to avoid it. It had been done the research of anti-bacteria activity test from crude extract of ethyl acetate and ethanol from skin and seed of Pulasan to bacterium Staphylococcus aureus and Escherichia coli with dilution method to determine Minimum Inhibitory Concentration (MIC) and Minimum Bakterisidal Concentration (MBC). The biggest MIC and MBC was respectively obtained from ethyl acetate extract that was 0,76 mg/ml, and ethanol extract that was 156,13 mg/ml. In general, skin and fruit seed extract of pulasan (Nephelium mutabile) has bigger resistance ones to bacterium Staphylococcus aureus compared to Escherichia coli

Researching peers and disaster vulnerable communities: an insider perspective

Conducting research among peers and communities that a researcher also serves may be both daunting and rewarding. Researching peers may make the researcher feel uncomfortable raising certain questions that are sensitive or that could be construed to be testing their competencies. This paper is inclined more towards showing that it is advantageous to be an insider, whose position can facilitate collection of information that could not have been accessed, or revealed to an outsider. The paper reports on fieldwork conducted in a low-income country in Sub-Sahara Africa as part of a doctoral study with communities affected by disasters and those that work with such communities. The paper demonstrates the complexities of conducting such research and provides some insights that may be useful to insiders, outsiders or “in-betweeners” embarking on fieldwork in low-income countries and among vulnerable population struggling with manifold stresses and shocks

Selective Binding of Aromatic Amines by Self-Assembled Monolayers of a Calix[6]crown-4 Derivative

A p-tert-butylcalix[6]crown-4 derivative immobilized on gold surfaces via self-assembly, endowed with a rigid cavity, can serve as a remarkably efficient sensor for aniline compared to alkylamines. The stability of the inclusion complex is attributed to the size fit and to the multipoint recognition motifs between the host monolayer and the guest aniline
