Abstract

There are many ways to improve added value of crude palm oil and core palm oil from alkyd resin for coating industry. Alkyd is made  by polymerizing  condense  ester of reaction acid of polycarboxylic and alcohol. Now a days resin alkyd are made from soya oil, sun flower oil and castor oil, which means that the prospect of resin alkyd from CPO is very good. This researcb used proportion of CPO. glycerol and Phtalic Acid weight is 2: 1:0,5, 2: 1: 1, and  2: 1 :2. The best result of this research in  percent weight of paint making is 2: I : 2.

Abstract

This research was motivated because the media in schools did not facilitate students in learning. The purpose of this research is to produce valid and practical hand outs. This type of research is development research (Research and Development), using 4D development, namely difine, design, development, and dissemination. The instruments used were questionnaires for material experts, language experts, response teachers, and student responses. The subjects of the trial in this study were 22 eighth grade students of Bukit Sundi 1 Public Middle School, but in this study the distribution was not carried out. In the defining stage, needs analysis, student analysis and task analysis were carried out, in the design of the design media design was carried out, at the development stage validation tests were carried out by 3 validators and practical tests by teachers and students at Bukit Sundi 1 Junior High School class VIIIe. Based on data analysis, questionnaire and language expert validation reached 85.30% and 85.50%. Practicality by teachers reached 88.14% and 87.00% students. Based on these stages, it is produced a valid and practical Corner type learning media

Abstract

Although writing skills occupy a central position in the Kurikulum Merdeka, students’ ability to produce procedural texts remains limited due to teacher-centred instructional methods and low learning motivation. This study aimed to analyze the effects of the Project-Based Learning (PjBL) model and learning motivation on procedural text writing achievement among Phase D, Grade VII students at UPT SMP Negeri 1 Pulau Punjung, as well as to examine the interaction between these variables. A quantitative approach was employed using a quasi-experimental method with a nonequivalent control group design. The sample was determined through cluster random sampling, resulting in one experimental class taught using PjBL and one control class taught using conventional instruction. Data were collected through a performance test in writing procedural texts and a learning motivation questionnaire, and analyzed using t-tests and ANOVA. The findings showed that PjBL had a significant effect on improving procedural text writing skills, with the experimental class achieving a mean score of 88.21, higher than the control class mean of 73.06 (t = 7.530 > t_critical = 2.002). Among highly motivated students, the experimental class mean score of 85.21 also exceeded the control class mean of 77.00 (t = 4.488 > t_critical = 2.048), whereas among low-motivation students, the experimental class mean score of 91.21 surpassed the control class mean of 68.87 (t = 7.113 > t_critical = 2.052). In addition, there was a significant interaction between the instructional model and learning motivation (F = 56.698 > F_critical = 4.01), indicating that the effectiveness of PjBL was reinforced across different motivation levels. The study concludes that implementing PjBL effectively enhances procedural text writing skills through contextual, project-oriented learning experiences and underscores the importance of integrating active learning strategies with motivation management within the framework of the Kurikulum Merdeka. The implications include theoretical contributions to project-based writing pedagogy and practical recommendations for teachers and educational institutions to design teaching modules that are adaptive to students’ psychological profiles, while opening avenues for further research on the use of digital media in PjBL for other text genres.
