Abstract

The production of eggshell powder as a water purifier has the potential to be utilized in Senoni Village, Sebulu District, Kutai Kartanegara Regency, East Kalimantan. Based on the results of initial observations the majority of residents there use Mahakam river water for daily needs where the water is still classified as cloudy. The purpose of implementing Community Service Activities is through socializing the production and utilization of eggshell powder as a water purifier and providing assistance through training activities on the powder as a water purifier. The approach method used were the lecture method, demonstration method, and mentoring method. Furthermore, the stages of socialization implementation as a solution to overcome the problems are as follows: 1) sample preparation stage, 2) socialization preparation stage, 3) implementation stage, and 4) evaluation stage. The results of the activity showed that an increase of 84% of participants knew the procedure for making eggshell flour, and 60% felt that it was very easy to make so it was very possible for participants to make it independently at their respective homes. This activity went well and smoothly without any significant problems. Participants are interested and want to implement the new knowledge that has been obtained through this socialization method, scientific findings results, and a short conclusion. The abstract should only be typed in one paragraph and one-column format.

Abstract

Heavy metal pollution is still a serious problem today. One method that can be used to remove heavy metal content from water is the adsorption method. In the adsorption method, the choice of adsorbent is very important to optimize the adsorption process. One of the materials that can be used as an adsorbent is tea waste. Tea waste contains cellulose, which can be used to bind heavy metal ions. This research was conducted to synthesize adsorbents using tea waste and then test their ability to adsorb lead ions. The adsorbent synthesis process is divided into several stages, namely washing, drying, refining, soaking in HCl solution, and drying again. The results of the adsorption tests conducted found that the tea waste adsorbent could remove 99% of the lead metal ion content in the water. The conclusion from these results is that the synthesis process has succeeded in making tea waste adsorbent that can adsorb lead ions in water.
