Abstract

Synthetic antioxidants are widely used to inhibit quality deterioration of the beef sausage. This study utilizes the high carotene content in Red Palm Oil (RPO) as a substitute for vegetable oil in beef sausage. This study aims to determine the sensory and chemical characteristics of beef sausage with the addition of RPO 5%, 10%, and 15%, and obtain the best formulation. Based on the study, it is known that beef sausage with the addition of RPO 10% received the highest overall sensory rating with an average score of 5.35 out of 7. The chemical characteristics of beef sausage include water content, protein content, and fat content that have met the standard of SNI 3820:2015. However, the ash content of beef sausage with the addition of RPO exceeds the maximum ash level that has been set by the SNI. The beta carotene level of beef sausage in the 5% RPO formula was 592.44 ppm, in the 10% RPO formula it was 596.89 ppm, and in the 15% RPO formula, it was 603.56 ppm. The 10% RPO formulation produces beef sausages with the best sensory and chemical characteristics.

Abstract

This article examines the relationship between teachers, curriculum and various problems in the education system through critical reflection. Teachers play a central role in curriculum implementation and its influence on the quality of student learning. Nonetheless, they are often faced with various challenges, including lack of welfare, limited professional training and high workloads, which impact on their ability to teach effectively. In addition, rigid curricula that are sometimes irrelevant to 21st century needs often hinder the development of students' cognitive and creative capacities. These problems highlight the need for a more flexible and adaptive curriculum revision and the contribution of all parties in creating a better education system. Collaboration between the government, education managers, teachers and the community is needed to produce an education that not only focuses on academic knowledge, but also on developing important life skills for students.
