Abstract

This study aims to determine the effects in physical chemistry class with the workshop sessions on measuring PKO viscosity by CV. Bina Agro Mandiri. The effects are evaluated through the enhancing of student's learning interest in the Physical Chemistry II class in Chemistry Program of the Islamic University of Indonesia, which presents a good avenue for this investigation. The study was conducted by classroom, practical and online action. The data were analyzed using a pie chart. Findings showed that the implementation of the practical was able to increase the student's learning interests. Through case analysis tasks, students participate significantly in the teaching-learning process.

Abstract

In this study, synthesis of a sodium alginate-coated rice husk-based biocomposite as a substitute adsorbent to lessen the negative impacts of congo red dye was conducted. A calcium chloride (CaCl2) solution was used in the sonication and encapsulation processes to produce the biocomposite material. X-Ray Diffraction (XRD), Scanning Electron Microscopy (SEM), and Fourier Transform Infrared (FTIR) Spectroscopy were used to characterize the biocomposite material. Adsorption experiments showed that the optimum pH was 3 and the dye concentration was varied between 10 and 50 ppm and adsorbent mass between 0.05 and 1.5 grams. Adsorption kinetics followed the pseudo-second-order linear model, while the adsorption isotherm model matched the Freundlich model. According to these results, biocomposites of rice husk and sodium alginate have a potential to be an environmental-friendly way to manage the textile waste.

Abstract

Household organic waste management remains a major challenge in Gadingsari Village, Sanden District, Bantul Regency. Due to low awareness and limited use of waste processing technologies, residents often burn or improperly dispose of organic waste. This community service program aimed to introduce maggot (Black Soldier Fly) cultivation as an innovative, environmentally friendly, and economically beneficial solution. The program was implemented using a Community Based Research (CBR) approach, consisting of four main stages: laying the foundation, planning, information gathering and analysis, and acting on findings. Participatory education and training were conducted to enhance the community’s capacity to manage organic waste as a productive resource. Evaluation results showed an increase in knowledge and skills, along with active community involvement. This initiative is expected to be integrated into the future Waste Processing Facility (TPST 3R) and serve as a replicable model for other villages. Overall, the program contributes to improving environmental quality and promoting sustainable community well-being.
