Dalam penelitian ini dipelajari asilasi fenol dengan asam asetat menggunakan katalis FeCl3, Al2O3, dan FeCl3/Al2O3. Masing-masing katalis dikarakterisasi dengan difraktometer sinar-X, FT-IR dan luas permukaan spesifik katalis ditentukan dengan metode metilen biru. Reaksi asilasi dilakukan pada temperatur 70 °C selama 120 menit dengan perbandingan fenol : asam asetat = 1 : 10. Berdasarkan analisis HPLC diperoleh konversi fenol paling banyak menggunakan katalis FeCl3 disusul Al2O3 dan FeCl3/Al2O3. Asilasi fenol dengan asam asetat menghasilkan asetofenon, fenil asetat dan produk lain.

In 2008, detection of typhoid fever was carried out using the tubex test in which it principally detects the IgM antibody that specific for Salmonella typhi O9 present in serum by employing the method of Inhibition Magnetic Binding Immunoassay (IMBI). The present study was aimed to evaluate results of blood sample examination of suspected typhoid fever patient using the tubex test, in order to confirm the typhoid fever diagnose. This research was retrospective study by analyzing 1.266 data of suspected patients obtained from Nikki Medika Clinic Laboratory. The samples were delivered to the Clinic Laboratory for laboratory examination since 2008 till October 2012. Each sample was examined using the tubex test. The results showed that 11.6 -27.8% of the blood samples were positive for typhoid fever while 70 -88.7% was negative.

The mixed of chitosan and an acetic acid solution was doing for 24 hour to make sure the solution are homogenic. After that, chitosan solution was stored to glass plate 10x10 cm. The glass plate that have been with chitosan solution then dried for 48 hours. A Chitosan Membrane that have made was keeped with the plate until it used.
