BIOREMEDIATION OF OIL DRILLING WASTE AT JOB PERTAMINA – PETROCHINA EAST JAVA TUBAN - EAST JAVA BIOREMEDIASI LIMBAH PEMBORAN MINYAK DI JOB PERTAMINA – PETROCHINA EAST JAVA TUBAN - JAWA TIMUR

Abstract

The research has been conducted in field scales with comparative descriptive analysis method, using land
farming bioremediation process by mixing oil sludge and soil to reduce water content in mud. To fix the soil
porosity compost has been added, this become he end-product bulking agent as well as nutrient sources for
degradation microorganism. The sludge came from Sukowati #4,#6, and #7 oil well JOB Pertamina –
PetroChina Tuban, East Java. The goals of the research are to study indigenous microorganism from the wells,
to understand the degradation differences between wells, and the benefits of bioremediation for the society. The
factors that influenced the microorganism oil degradation performance are end-product compost, and organic
fertilizer. The society could use the bioremediation water for land filling and bricks. The more time material
given for the material to degrade the better the result
