Abstract

Implementation of integrated project in chemical engineering courses has shown positive impact on students’ understanding, teamwork, critical thinking, and communication. In this case, an integrated project covering three different courses in chemical engineering, namely Reaction engineering, Process modelling and simulation, and Separation process was formulated on palm-oil based biodiesel production and introduced to students. The response from questionnaire was recorded and analyzed by using Excel software. More than 90% of students agree that the project helps them to understand the course and prepare for test or exam. While more than 70% of students want to see this type of project for other courses. Majority of students think that collaboration and teamwork help them to finish the project and doing integrated project saves their time to do assessment. Beside improving their soft skill like critical thinking, students can also sharpen their technical skills in solving the problems, especially on process flow drawing, operation of simulation tool, calculation technique, and search for suitable information and data. Through this integrated project, students could explore the connection among courses in Chemical Engineering program and implement the taught concepts in solving engineering problem, which can be challenging things to achieve during online learning.

Abstract

In this study, polylactic acid (PLA) was proposed as a material for producing bioplastics due to the desirable properties, including high processability, low cost, and good transparency. However, the degradation of PLA as a bioplastic remains a significant challenge. To address this problem, PLA was modified by blending with a bio-filler, in the form of calcium carbonate (CaCO3) prepared from eggshell powder (ESP). The CaCO3 filler in form of ESP was incorporated into PLA using the solution casting method. The parameter being varied was the ESP loading, ranging from 0 wt% to 20 wt%. The results showed that the inclusion of eggshell-derived filler in PLA increased tensile strength and Young’s modulus by 10%, from 24.12 to 26.61 MPa, and 162%, from 3022 to 7932 MPa, respectively. The degradability of composite was done through burial test, which the weight of PLA/ESP-20wt% was decreased by 11.11 wt% after 3 weeks. This suggests that eggshell waste has the potential to serve as an effective filler to improve the mechanical strength and degradation of PLA.
