Abstract

In this research, a series of batch laboratory experiments were conducted to examine the feasibility of Meandg’s (Litsea sp) saw dust for the removal of cadmium from simulated aqueous solution by using adsorption method. The research was carried out by studying the influence of pH of initial solution, contact time, adsorbent dosage, stirring speed, and the initial concentration of cadmium. The sawdust particle size used was 150 mesh and the experiments were conducted at room temperature of 27oC (±2oC). The residual concentration of cadmium from all batch experiments were analyzed using Atomic Adsorption Spectrophotometer (AAS) and each component equilibrium data was analyzed using Langmuir and Freundlich adsorption isotherms. The research findings shown that the optimum conditions are found to be at the pH of 6, the initial concentration of cadmium of 500 ppm with contact time of one hour, 3 gram of sawdust, and the optimum stirring at the speed of 350 rpm. The adsorption capacity of medang sawdust according to Langmuir and Freundlich isotherms are found respectively to be of 2.29 mg/g and 0.55 mg/g.

Abstract

The research entitled "Development of Google Slide-Based Interactive Learning Media on Chemistry Subjects in Class X High School Materials on Atomic Structure", has been carried out using Research and Development (RD) research types and the ADDIE model. The purpose of this study is to develop a google slide learning media that is proven to be suitable for use. The google slide-based learning media on atomic structure material was tested for feasibility by expert validators (media and materials) and students of MAS Darussyari'ah, Banda Aceh city. The instrument in this study was a media feasibility questionnaire sheet and student response sheets. The results of data analysis showed that the google slide media was very feasible to use with the percentage of media feasibility validation results of 93%. Students responses to the media showed a positive response with a percentage of 86.37% which was categorized as very good. Based on the data obtained, it can be concluded that the Google Slide media is very suitable to be used as a learning medium and received positive responses from students.

Abstract

Ulee Lheue Beach is one of the marine tourism sites in Banda Aceh. Its appearance, apart from attracting visitors to enjoy the beauty of the shore, also has consequences for piles of garbage thrown carelessly by the visitors to the shoreline which has an impact on environmental damage. In addition, the visitors tend to heed the government’s appeal to strictly commit to health protocols such as social distancing, gathering prohibition, and wearing masks while they visit the tourism spots. Therefore, this community outreach sought to map the knowledge of the tourists about waste and its impact on tourism sites and its relation to the dangers of Covid-19. This service employed mixed methods (quantitative and qualitative). The survey results showed that the visitors have fairly good knowledge regarding the dangers of waste and Covid-19 yet still uninternalized in their daily attitudes. Thus, the service team provides education through leaflets and videos on Youtube channels, hoping that the visitors would have higher commitment towards the environmental hygiene and health protocols at tourist sites.
