Abstract

As people's consumption levels increase, the plastic waste produced increases, so that plastic waste becomes the first environmental problem in Indonesia, especially in Kelurahan Kampung Jua Nan XX, Kecamatan Lubuk Begalung, Padang City. Plastic waste takes a long time to disintegrate and can decompose into microplastics which can be spread into soil and water. The presence of microplastics in soil and water can contaminate plants, shellfish, fish and even salt which ultimately accumulates in the human body through the food chain cycle. Therefore, a solution is needed so that the presence of plastic waste can be handled properly and carried out optimal management. One solution to utilizing plastic waste is by making ecobrick products that are useful and have high selling value and can be a livelihood opportunity. The aim of this activity is to increase public awareness and concern for the environment in order to create a clean and healthy environment through the management and processing of plastic waste. This activity was carried out in kelurahan Kampung Jua on 27 October and 9 December 2022, with the participants in this activity being PKK women from Kampung Jua Nan XX Village. The methods used were education regarding the threat of plastic and microplastic waste and training through demonstrations on making chairs from ecobricks. The results of this activity can increase public awareness of the dangers of plastic waste, limit the use of plastic bags and manage plastic waste at the source as an effort to reduce plastic waste generation and empower the community to maximizing the economic value of existing waste in a sustainable manner.

Abstract

Activated carbon from corn stalks (Zea mays L.) has been successfully synthesized by the dehydration method and used as a supercapacitor electrode. Corn stalk powder was dehydrated with 1 MH2SO4 and activated with 5 M NaOH at a carbon and activator mass ratio of 1:4 with a heating temperature of 800°C and an N2 gas heating rate of 10°C/minute for 1 hour. SEM characterization results show that heterogeneous pores have formed on the surface of corn stalk-activated carbon. EDX results showed a carbon percentage of 54.82%; this data is supported by FTIR results, which show several functional groups containing C and O atoms on the surface of activated carbon. Based on desorption adsorption isotherm analysis, the activated carbon shows H4 type with a specific surface area of 117.973m2/g, average pore diameter of 1.730 nm and total pore volume of 0.1021 cm3/g. Measurement of the electrochemical properties of corn stalk activated carbon with a three-electrode system and 3 M KOH electrolyte showed a specific capacitance value of 133.9 F/g, power density 225.2 W/kg and energy density 0.863 Wh/kg. The synthesis of activated carbon through the dehydration method offers advantages in terms of simplicity in preparation, low cost, shorter synthesis time and being environmentally friendly.
