Abstract

Electrical storage and distribution devices become important in next generation to help integrate more renewable energy intothe electricity grid. Supercapacitor technology is considered the most promising alternative to Li-ion batteries, which have limitedLithium material. However, the low energy density is a weakness of supercapacitors, even though they have a high-power density.Activated carbon-based supercapacitor electrodes have ideal potential for development. The inherent attributes of activated carbon,pore properties, and functional groups, are responsible for improving the performance of supercapacitors. The main challenge for theresearchers is the pore size distribution, micro (<2nm), meso (2–50 nm), and macro (>50 nm), which varied in activated carbon.Micro pores have an impact on increasing the value of specific capacitance values which will encourage an increase in energy density.Meso pores have an impact on the overall accessibility of the electrode surface by electrolyte ions. Future studies will emphasize oncarbonization and activated carbon activation techniques to improve the surface quality of activated carbon.

Abstract

Vegetable oil production of malapari (Pongamia pinnata L. Pierre) fruit remains peels that haven't been utilized. Malaparifruit peel is potential for activated carbon. The purpose of this research is to use malapari fruit peel waste as raw material forproducing activated charcoal. Samples were carbonized at temperature of 400°C and continued activation with phosphoric acid2% and physical activation at temperature of 750°C by flowing steam for 60 minutes. The process resulted in the Optimumcondition. It yields 54% charcoal recovery, moisture content of 8.6%, volatile matter of 11.85%, ash content of 24.73%, fixedcarbon of 63.42%, benzene adsorptivity of 10.15%, metilene blue adsorptivity of 93.89 mg/g, iodine adsorptivity of 648.62mg/g, and specific surface area of 348.11 m2/g. Activated carbon in this study is below Indonesian standards, which is influencedby the activation retention time.

Abstract

Plants such as cacao (Theobroma cacao), avocado (Persea americana), puspa (Schima wallichii), sengon(Falcataria mollucana) and tarik angin (Usnea sp.) are widely planted in the community for fruit or wood needs.Periodically, they harvest these types of wood for common uses or plant rotation purposes. In general, wood sorting is usedfor simple construction or even conventionally burned. In addition to conventional combustion techniques to produce charcoal,there is another product that can be produced, namely liquid smoke - using a combustion technique by adding a condenserto produce liquid smoke. Liquid smoke contains organic chemicals with various benefits. This study investigates the organicchemical content of liquid smoke of cacao, avocado, puspa, sengon, and tarik angin wood. The five types of materialswere carbonized using a pyrolysis reactor around 400oC. Liquid smoke was obtained by condensing fumes mechanism.Analysis of organic liquid chemical using Gas Chromatography Mass Spectrometer (GCMS) Pirolisys Type QP2010and High Performance Liquid Chromatography (HPLC). GCMS analysis showed that cacao liquid smoke has thehighest concentration of acidic group, of the 45.53%, where the concentration of acetic acid was 31.81%. The presence ofthe highest phenol group was in avocado liquid smoke as much as 56.86%, where the concentration of phenol compoundsreached 41.92%. The acid and phenol groups are type of compounds contained in liquid smoke and have a lot of benefits.
