Abstract

This study aims to see how student life skills, especially in vocational skills, after using the integrated CEP PjBL learning model. This study uses an associative method with a quantitative approach. Taking population and samples using total random sampling with the population is also the sample used in the study. Collecting data using instruments including, the CEP integrated project-based LKPD which is used as a practical guide as well as a reference in practicum supervision, the model implementation observation sheet to see the implementation of learning carried out to teach students, the life skills observation sheet used in direct life skills assessment when Available learning, as well as the responsibility of the student questionnaire used to measure students' life skills in learning using the CEP integrated PjBL model. The results showed that learning using the CEP integrated PjBL model was proven to be able to help students develop life skills in the aspect of vocational skills so that students had entrepreneurship. This can be seen from the proportion of students' vocational proficiency, namely 74.89%, where the competitiveness of students in sales and the work ethic possessed by students can be categorized as very good, namely 80.27% and 82.45%. The generic life skills of the students were classified as good with the proportion of 77.18% and the specific life skills of the students were classified as good with the proportion of 73.94%.

Abstract

Fuel oil reserves are currently decreasing due to an imbalance between the increasing need for fuel consumption and the finding of new sources to fulfill these needs. On the other hand, plastic waste is also an environmental problem. Plastic waste is a synthetic polymer made from petroleum that is difficult to decompose in nature. An alternative route for waste must be applied to prevent a further environmental problem. Catalytic cracking is one alternative that converts plastic waste into liquid hydrocarbons. This research aims to determine the quantity of gasoline produced from the catalytic cracking process of polypropylene (PP) plastic waste using modified H-USY and Cr-USY catalysts. The sample used was plastic waste derived from bottled water packaging. The plastic waste was cut into small pieces, weighed, and then cracked thermally and catalytically with a catalyst: sample ratio 1:10. The results showed that catalytic cracking of PP waste using the H-USY catalyst produced 20.73% gasoline, while using the Cr-USY catalyst resulted in 14.4% and 13.68% gasoline using Cr-USY catalyst 0.1% and 0.3% respectively.
