This study is aimed to evaluate the electricity generation from microbial fuel cell (MFC) and to analyze the microbial community structure of city wastewater and anaerobic sludge to enhance the MFC performance. MFCs, enriched with palm oil mill effluent (POME) were employed to harvest electricity by innoculating of Klebsiella oxytoca, collected from city wastewater and other microbes from anaer...

Generation of wastes in the form of palm oil mill effluent (POME) is unavoidable due to increase in oil palm development worldwide. Direct discharge of POME into receiving water bodies is strongly discouraged due to high chemical and biochemical oxygen demand concentrations, respectively. Aerobic granulation technology features microbial aggregates generated following immobilization and cell-to...

Conventional grading of oil palm Fresh Fruit Bunches (FFB) is still currently manually carried out in palm oil producing industries. The most critical part of the grading process is the categorization of the oil palm fruit bunches according to their ripeness. This paper presents a computer assisted photogrammetric methodology which correlates the color of the palm oil fruits to their ripeness a...

The demand for biofuels has begun to shift from first-generation second-generation biofuels. One of the already planned in government’s roadmap is renewable diesel hydrotreatment palm oil. By 2040, share projected reach 1.4 million kL per year, contributing 9% biofuel blend program. As world’s largest oil producer and consumer, Indonesia opportunity achieve a circular economy value chain by uti...

A method for the aerobic treatment of palm oil mill effluent (POME) was investigated in shake-flask experiments using a consortium developed from POME compost. POME was initially centrifuged at 4,000 g for 15 min and the supernatant was enriched with (NH4)2SO4 (0.5%) and yeast extract (0.25%) to boost its nitrogen content. At optimum pH (pH 4) and temperature (40°C) conditions, the chemical oxy...

An experimental study was conducted on the adsorption of color from biologically treated POME using palm kernel shell (PKS) and empty fruit bunches (EFB) as natural biosorbents, and activated carbon prepared from them by microwave and chemical activation with potassium hydroxide (KOH). BET surface area of all sorbents was determined and 1252 m 2 .g -1 was recorded for activated carbon prepared ...

The increasing of crude oil prices recently in the world, the need for an alternative source of fuel in the Indonesia is urgently required. In addition, growing concern about climate change is driving the need for “low-carbon” fuels. One highly potential form of renewable and low-carbon fuel is biogas from anaerobic digestion of organic wastes. Anaerobic digestion is a naturally occurring proce...
