Abstract

The vegetable waste is one of the biomass types that it can produce electrical energy.  This article focused on electrical production of vegetable waste using microbial fuel cells (MFCS) MFCs is the primary type of the bioelectrochemical system (BECs) that to replaces the biomass to electrical energy spontaneously by activity metabolism of the microorganism. The objectives of this work were to investigate the process of electrical production from Chinese cabbage and the combination of the materials to produce the electrical energy. The experiment was carried out in a laboratory-sall such as mini reactor MFCs, Chinese cabbage as the material of vegetable waste and EM4 as the fermentation. Sample combination was consist of two parts that the first part was used 1 kg Chinese cabbage, 2 liter water and 20 ml EM4. The second part was used 2 kg Chinese cabbage, 1 liter water and 20 ml EM4. The result showed that the electrical voltage in part 1 at 0.362 V and pH at 6 was lower than the electrical voltage in part 2 at 0.724 V and pH at 7. Declining electric energy is influenced by pH as microorganisms living place and the formation process of attached media at the electrode.

Abstract

Plastic waste is a problem that has to be taken seriously for the pollution of the environment, especially for land contamination. For now, the handling of plastic waste is normally disposed (landfills), burned, or recycled (recycle). The burning of plastic waste is usually carried out by the pyrolysis method to produce plastic oil. To get the maximum results needed further analysis in the form of purification by distillation, where the distillation is a method that can be used for advanced analysis, one with a distillation column. Fractional distillation often called the distillation column is to separate liquid components, two or more, of a solution based on differences in their boiling points. This distillation can also be used to mix with a boiling point of less than 20°C and work at atmospheric pressure or low pressure. Application of this type is used in the distillation of crude oil industry, to separate the components in the crude oil distillation Differences simple fractionation and distillation is the fractionation column. In this column, warming occurs gradually with different temperatures on each license plate. Different heating is intended for refining distillates from the plates underneath. Getting to the top, the less volatile liquid. The distillation process depends on the characteristics of the vapor pressure of a liquid mixture of components.The distillate was obtained at a temperature of 195oC, 200oC, 220oC, 235oC, and 240oC and the most products component of pyrolysis plastic in previous research was obtained at 195oC, 200oC, and 220oC
