Kelapa merupakan tanaman yang mulai dari akar sampai buahnya dapat di manfaatkan, salah satu bagian buah kelapa jarang manfaatkan bahkan slalu menjadi limbah yaitu tempurung kelapa. Limbah dimanfaatkan sebagai pengganti bahan bakar terbaru dijadikan arang dalam pembuatan briket dengan campuran perekat dan kimia oksidator KMnO4. Penelitian dilakukan bertujuan untuk mengetahui pengaruh presentase...

Background: Estimated Fetal Weight (EFW) needs to be as accurate possible reflect the actual condition of fetus for labor-management planning. Risanto’s formula is one easy use estimate fetal weight using fundal height (FH). But, oftentimes, measurement in overweight pregnant mothers hard done precisely due thickness abdominal subcutaneous fat layer. Therefore, there a possibility decrease EFW’...

background and purpose:the presence of dyes in wastewaters may cause serious problems for the environment because of their high toxicity to aquatic organisms and unfavorable aesthetical impact. in the present study, multi-walled carbon nanotubes (mwcnts) were used for removal of anionic dyes direct blue 106 (db106) and acid green 25 (ag25), from water samples. materials and methods:mwcnts were ...

This work was carried out during the two seasons of 2008 and 2009 aiming to study the effect of different levels of cattle manure and biofertilizers (phosphorein and/or nitrobein) as well as their interactions treatments on the growth, sepals, seed yields and some chemical constituents of roselle plants. The obtained results show that all levels of cattle manure and inoculated biofertilizers an...

The effects of exposure to environmental tobacco smoke (passive smoking) on pulmonary function of non-smoking, healthy Iranian men (n = 167) and women (n = 108) were investigated. There were significant reductions in % predicted FEV1 (5.7%), forced vital capacity (FVC, 4.6%) and forced expiratory flow 25-75% (FEF25-75, 9.9%) among men exposed to cigarette smoke (n = 78). The adverse effect of p...

Muscovy duck was in demand by breeders because of easy maintenance, fast growth, and quick yielding. But muscovy ducks have a high level ration consumption, resulting production costs. An alternative solution used cheap, abundant, good feed nutrient ingredients, including banana stems. The objective the research to obtain best performance served complete based on method an experimental with com...

Flavobacterium branchiophilum a causative agent of Bacterial Gill Disease (BGD) is a filamentous gram-negative bacteria which produce yellow round colonies in cytophaga agar medium. The outbreak of disease were reported from different part of world. In this study we examined 75 fish sample from farms with a recirculating aquaculture system (n=25), pools with a well water source farms (n=25) and...

The eco-friendly compounds especially plant extracts have emerged as green corrosion inhibitors for metals and alloys. inhibiting impact of Roselle extract on Cu-Zn alloy in 1M HNO3 solution was studied by weight loss, electrochemical impedance spectroscopy (EIS), potentiodynamic polarization (PDP). It found that acts a good mixed-type inhibitor acid solution. rate decreases with increasing the...
