Methods used qualitative method consisting research first influence comparis...

This investigation aimed at production of gluconic acid by fungal species isolated from soil in Keffi. Standard microbiological methods were employed for isolation and identification the isolates. The yields produced different isolates fungi determined using gas chromatograph mass Spectrometry. occurrence showed that Rhizopus oryzae was 100%, Aspergillus carneus 75.0%, niger 75.0% terreus 100% ...

Zat warna kunyit dapat digunakan pada pencelupan dengan berbagai kondisi pH dan suhu. Pengolahan ekstrak menjadi serbuk menggunakan spray dryer menghasilkan zat yang lebih tahan lama serta kemudahan mobilisasi konsistensi penggunaan. Perilaku acuan penilaian kestabilan tersebut selama penyimpanan. dihasilkan melalui proses ekstraksi suhu kamar 24 jam. Sebagian larutan dibuat sebagian lagi tetap...

The motive of the research is production bioethanol from deffated seeds cake Rothmannia longiflora and analysis its physical/chemical properties. fermentation process was optimized for maximum ethanol yield considering four parameters; temperature, pH yeast concentration. statistical revealed that temperature are most influential parameters affecting yield. 11.14 g/cm3 observed at following opt...

The removal of disulfide oil (DSO) from contaminated soil was studied by the bioremediation method and the influence of electrokinetic on the bioremediation process was investigated. The bacillus subtilis strain was used in the bioremediation process. The effects of humidity, time and DSO concentration in soil was studied. The experimental results for the bioremediation of DSO show, the removal...

Polycyclic aromatic hydrocarbons (PAH) are toxic, mutagenic, and carcinogenic compounds. Removal of these compounds has a great importance for environment. Removal of PAHs from soil is difficult as these chemicals are persistent in the soil. In this research, bioremediation of soil contaminated by (PAH) using Bacillus subtilis DSMZ 3256 (B.subtilis) strains was studied. The effect of electrokin...

Pembangkit Listrik Tenaga Gas (PLTG) merupakan pembangkit dengan keunggulan waktu pengoperasian yang singkat daya pembangkitan relatif besar. Dibalik kecepatan tersebut untuk dioperasikan terdapat kelemahan yaitu tingkat efisiensi tergolong rendah atau boros dalam penggunaan bahan bakar. Pada saat proses di industri sering terjadi perubahan permintaan pasokan beban, memenuhi harus siap tertutam...
