Abstract

The Coronavirus Disease 2019 (COVID-19) pandemic has an impact on the physical health aspect and the psychology of the community, especially the emotions to experience stress and anxiety. This psychological impact is not only experienced by groups who are vulnerable to COVID-19 but also teenagers. The information circulating on social media about COVID-19, both factual information or hoaxes, triggers stress and anxiety among teenagers. This community service is carried out to provide education to teenagers on how to be wiser using social media so that they can anticipate anxiety and stress as a result of using social media. This activity was carried out for high school teenagers who are members of the youth organization in Ngudi, Blora, by providing counselling on two subjects, namely 1) the SIFT method to anticipate hoaxes circulating on social media, 2) how to anticipate stress as a result of using social media. The results of this activity are participants' understanding of how to behave and act on information obtained from social media, as well as participants' understanding of ways to anticipate stress during the COVID-19 pandemic. In general, the participants were enthusiastic about participating in this activity and get benefits.

Abstract

Batik wastewater contains various chemical compounds, such as dyes, synthetic compounds, heavy metals, and organic compounds that can harm the environment. Therefore, proper waste management is required. The use of alum as coagulant in textile wastewater treatment is commonly used, but it is not effective enough to remove wastewater colour and reduce COD. This study aims to modify alum-based batik wastewater treatment using (i)double coagulant by combining alum - FeSO4; and (ii)coagulant-oxidizing agent with combination of alum – chlorine. This experimental study consisted of two stages, the first experiment aimed to determine the optimum composition dose of alum – FeSO4 and alum – chlorine in depositing waste pollutants, reducing the colour and pH of the effluent; the second experiment aims to determine the effect of alum - FeSO4 and alum - chlorine at the optimum dose in reducing the COD. The results showed that alum–chlorine in various compositions reduced colour ten times and precipitated pollutants two times better than alum-FeSO4. The optimum concentration ratio of alum:chlorine is 1:1 (1.2 g/L alum : 1.2 g/L chlorine). This dose reduced the pH to 8; depositing 0.385 g pollutants; removed 99.57% wastewater colour; and decreased COD from 686.9 mg/L to 235.53 mg/L
