Abstract

The process of bentonite impregnation with cellulose has been studied. Cellulose extracted from rubber wood and clay from natural bentonite was activated. The impregnation process is performed using thiourea as impregnant agent. The impregnation results were characterized by using FT-IR spectrophotometer then the material was used as congo red dye adsorbent. Factors affecting the adsorption process were studied by kinetic parameters and thermodynamic parameters. The FTIR results indicate the impregnation process was succesfully conducted the characterization by FTIR indicated resources of typical absorption of the hydroxyl (OH) and vibrational (-CH) vibration function groups as specific groups of cellulose Appearing at wave numbers 3464.15 cm-1 and 2368.59 cm-1 from impregnated material. Vibration Si-O-Si and Al-O-Si as bentonite-specific strands groups Appear at 1465.9 cm-1 and 609.51 cm-1 wavenumbers in the impregnated spectra. The adsorption thermodynamic study showed that the adsorption and adsorption capacity of the cellulose-impregnated bentonite adsorbent reached the optimum point at 50 ° C at 43.47 mol / g and energy of 11.62 kJ mol. The optimum enthalpy (ΔH) of cellulose bentonite was 143.13 kJ/mol and the minimum entropy (ΔS) at concentration of 40 mg/L was 0.207 kJ/mol.

Abstract

This study aims to analyze the influence of emotional intelligence on the communication ethics of Karang Taruna teenagers in the RT 005 Mustika Jaya Bekasi environment, with the background that emotional intelligence is a key factor in forming effective and ethical communication among teenagers. Emotional intelligence, which includes the ability to recognize, understand, and manage one's own and others' emotions, is believed to play an important role in encouraging ethical communication behavior, such as honesty, responsibility, and respect for others. Karang Taruna teenagers as an age group that is experiencing dynamic emotional and social development, often face challenges in maintaining communication ethics due to low emotional intelligence, which can trigger internal conflicts, misunderstandings, and decrease the quality of social interactions. Through a quantitative approach, this study examines the relationship between emotional intelligence and communication ethics, with the hope of providing both practical and academic contributions in efforts to strengthen the character of the younger generation who are able to communicate politely, ethically, and build positive social relations in society, especially in youth organizations such as Karang Taruna RT 005 Mustika Jaya Bekasi.
