Abstract

High school chemistry learning often struggles with abstract concepts such as molecular structures, chemical bonding, and reaction mechanisms. Utilizing chemical software like ChemDraw offers a viable solution; however, preliminary observations indicate that its adoption remains limited in classrooms. This community service program aims to enhance students' digital visualization capabilities while equipping them with essential technological skills required in 21st-century education. The intervention was delivered through module-based hands-on training, paired with interactive video tutorials to facilitate self-paced learning. The curriculum covered the fundamental ChemDraw interface, organic compound drawing techniques, and reaction mechanism simulations. Post-activity evaluations revealed highly positive outcomes, with 96% of students finding the material accessible and 98% reporting a substantial increase in conceptual knowledge. Ultimately, this training effectively boosted student motivation and fostered a stronger mastery of digital competencies within chemistry education.

Abstract

The Taberau plant (Phragmites australis) grows abundantly across the peat swamps of Central Kalimantan, particularly in Tanjung Sangalang Village. Despite its high biomass potential, it is widely dismissed as an invasive weed and remains underutilized. This community service program aims to empower local farmer groups by introducing a simple, local wisdom-integrated pyrolysis method to convert Taberau into multifunctional biochar. The program was executed through a comprehensive framework including local coordination, site surveys, Focus Group Discussions (FGD), simple reactor fabrication, hands-on demonstrations, and empirical evaluations. The production trials demonstrated that 20 kg of raw Taberau biomass yielded 5 kg of biochar, achieving an efficiency rate of approximately 25%. The training workshop, which engaged 40 local farmers, significantly elevated participants' technical comprehension, as evidenced by post-test scores exceeding 90% across all pedagogical indicators. Furthermore, 85% of respondents reported a substantial increase in environmental literacy, and 87.5% validated the tangible socio-economic benefits of the program. Ultimately, this initiative serves as a highly replicable model for circular economy practices in regions facing similar biomass management challenges.
