    PENCAMPURAN KARBON AKTIF DAN BENTONIT SEBAGAI ADSORBEN DALAM PERBAIKAN BEBERAPA PARAMETER MINYAK GORENG BEKAS
    (2016-10-19) Fakhruddin; Mukhtar, Akmal; Tamboesai, Emrizal M
    To determine the quality of cooking oil can be done by various test parameters. This research was carried out by mixing activated carbon and bentonite as adsorbent with multiple comparison. Adsorption used in the researched was using the batch method. Test parameters were performed on cooking oil before and after adsorption. The results obtained, the decline efficiency acid number reached 73,81% with the use of adsorbent 4:1 (g) (bentonite:activated carbon), the decline efficiency water content of 94%, the decline efficiency peroxide reached 75% and the decline efficiency number of iodine with the 39,28% with the use of adsorbent 3:2 (g) (bentonite:activated carbon). Efficiency decrease in metal content reached 80,84% for Pb and 91,52% for Cu with the use of adsorbent 4,5: 0,5 (g) (bentonite:activated carbon).

    PENENTUAN KEMATANGAN MINYAK BUMI (CEUDE OIL) SUMUR MINYAK PETAPAHAN-KAMPAR, RIAU DENGAN MENGGUNAKAN PARAMETER ISOPRENOID
    (2016-05-02) Fazlin; Tamboesai, Emrizal M; Sophia, Halida
    In this study, crude oil samples from Petapahan were tested and characterized with isoprenoid parameters. Determination of thermal maturity level aims to determine the feasibility of petroleum wells to be exploited because there are many new wells of petroleum unexploited in the Riau area. Determination of maturity crude oil performed by analysis saturated fractions. Saturated fraction of the wells petapahan used to determine the maturity of crude oil based on parameters isoprenoid, n-alkane and carbon preference index were analyzed using gas chromatography-flame ionize detector (GC-FID). Based on the value Pr / Ph, Pr / n-C17, Ph / n-C18 and its CPI, the maturity level of petroleum from oil wells Petapahan, Langgak and Pendalian ripe with order levels of maturity and quality of the oil is oil Petapahan> Langgak> Pendalian as indicated by the value of Pr / Ph (2.29; 2.27; 2.29), the value of Pr / n-C17 (0.44; 0.57; 0.44), the value of Ph / n-C18 (0 , 20; 0.22; 0.25) and the CPI (1.095; 1.087; 1.069) respectively.
