Abstract

The Independent Curriculum is an intracurricular curriculum in which the material is maximized so that students have more time to develop learning ideas and expand their competency. The Mobilizing School's role in implementing the Independent Curriculum is to create an operational curriculum that satisfies the learning requirements of students. Schools also provide infrastructure and human resources to facilitate the Independent Curriculum's implementation. In this study, a qualitative descriptive approach was used to describe the topic about the circumstances and information gathered during the observation, as well as the challenges encountered, so that it became valuable knowledge and input to policymakers in revising the curriculum. The findings of this study reveal that the Independent Curriculum has been implemented maximally and stably in Mobilizing Schools, albeit there are still numerous inadequacies and challenges to its implementation. The ability of school leaders and teachers to implement changes is critical in the implementation of the Independent Curriculum in Mobilizing Schools. The principle, as a leader and facilitator, must be able to influence the mentality of the human data source staff in order to carry out reforms at the school and ensure that the Independent Curriculum is implemented efficiently.

Abstract

Calophyllum Inophyllum (nyamplung) Oil is recognized as a promising non-edible vegetable oil for the development of sustainable green energy lubricants. This study aims to improve the physicochemical characteristics of nyamplung oil through a two-step transesterification followed by esterification using trimethylolpropane (TMP), and to assess its tribological performance. The refined oil exhibited a flash point of 212 °C (ASTM D92) and a pour point of 8 °C (ASTM D97), indicating excellent thermal and flow stability. The kinematic viscosity was 38.3 cSt (ASTM D445) and the density 0.88 g/cm³ (ASTM D4052), both within industrial lubricant standards. The acid value decreased markedly from 36.5 to 1.62 mg KOH/g, while the iodine value (0.006 g I₂/100 g) and peroxide value (0.23 Meq/kg) demonstrated chemical stability. FTIR analysis confirmed the formation of ester functional groups, and GC–MS results showed a balanced distribution of saturated and unsaturated fatty acids. Overall, the modified Calophyllum Inophyllum Oil fulfills key technical criteria for eco-friendly green energy lubricants and shows strong potential as a renewable alternative to conventional mineral-based lubricants in industrial applications. Nevertheless, its crude form presents several drawbacks, including high acid and peroxide values as well as poor oxidative stability.
