Abstract

This Community Service (PKM) is conducted through counselling in the densely populated ​​Peninggaran Barat sub-district, Kebayoran Lama, South Jakarta. The purpose of this PKM is to provide input that is expected to be a solution to the concerns of mothers regarding dependence on gadgets that are detrimental to their environment in general, and children in particular, especially early childhood. Currently, dependence on gadgets is something that cannot be avoided, coupled with the rapid development of digital and information technology. From these changes, mothers are the ones who feel the impact the most. Mothers are required to be able to accompany their children in learning and synergize with teachers at school, especially for early childhood. This PKM uses the constructivism paradigm method, namely delivering material and discussions about the importance of literacy and implementing a culture of literacy through counseling The results of the PKM show that mothers are increasingly aware of the importance of literacy so that they can comfortably accompany their children to learn , use gadgets intelligently, and can provide solutions to conflicts that occur with their environment.

Abstract

Disposable batteries are commonly found in dry batteries (or zinc-carbon batteries) that are discarded and converted into waste. Zinc-carbon batteries have a physical component, a carbon rod that has a graphitic carbon component that has a black pigment. This black pigment is utilized as an alternative black carbon material for the manufacture of whiteboard marker ink. This research aims to utilize graphite carbon from waste batteries as a pigment in whiteboard marker ink and test the formulation of ink samples. The supporting materials in this research are glycerin, thinner, gum arabic solution, and emulsion. The best ink sample has a density value of 1.35 g/cm3, a viscosity of 0.13 Poise, a transmittance of 72 lux, a pH of 7.67, adhesion has a dense wet nature and moderate absorbency, and non-volatility of 75% ink using a carbon mass of 6.5 grams and the ratio of thinner and glycerin is 2:5.
