Abstract

The purpose of this activity is to overcome the issue of tedious presentations by the students of SMAN 10 Palangka Raya. This issue occurs due to the lack of students' digital literacy, affecting their public speaking abilities. For this reason, the team provided the use of digital media mentoring to students for problem-solving. The digital media used in this activity were Prezi and Canva. The mentoring used explanation and learning-by-doing methods. The activity was held on May 2023. The students received the information well. It was proven by the questionnaires that were answered, 92.3% stated that this activity was useful to enhance the knowledge of the use of digital media in presentations. They stated that this activity could help make presentations more interesting and interactive.

Abstract

This study presents the preparation and characterization of activated carbon derived from rubber seed shells using potassium hydroxide (KOH) activation. The raw material for this investigation was obtained from rubber seed shells collected from local rubber plantations in Palangka Raya. The activation process involved the use of the chemical activator KOH at a 1:1 carbon-to-KOH ratio in 200 mL of distilled water for a duration of 24 hours. X-ray Diffraction (XRD) analysis confirmed that the resulting activated carbon exhibited an amorphous structure, and all Fourier-Transform Infrared Spectroscopy (FTIR) spectra indicated the presence of functional groups in the activated carbon. The activated carbon possessed a porous structure with a surface area and total pore volume of 2.24 m2/g and 0.02 cm3/g, respectively. These findings necessitate further optimization of the activation process to achieve a larger surface area, thus enabling its application in electronic materials, water treatment, and various other fields.
