Abstract

Purun waste and sawdust are generally thrown away, not used by the community. This study examines the utilization of purun waste and sawdust with polyurethane adhesive. Purun is mixed with ironwood sawdust in a ratio of 5% and 95%; 10% and 90%; 0% and 100%. The adhesive used is 10% of the material weight. The particleboard is hydraulically pressed at a temperature of 105oC with a pressure of 15 kg/cm2 for 15 minutes. Each treatment is repeated 3 times. The results show that particleboard made from purun waste and sawdust has physical properties (water content and density) and mechanics that meet the requirements of SNI. 03-2105-2006, except for the MoR value. The addition of purun in the composition of particleboard materials does not significantly affect the properties of particleboard so it can be used as an alternative raw material.

Abstract

This study aims to examine the role of school principals in Gunung Mas Regency in cultivating a growth mindset as the foundation for deep learning. The research employed a descriptive method through document analysis using the Mindset Mapping Instrument developed by the Directorate General of Teachers and Education Personnel (GTK Dikdasmen) in 2025. The findings show that most principals fall within the Fixed–Growth category (48,2%), followed by Growth–Fixed (21,4%), Growth–Growth (17,9%), and Fixed–Fixed (12,5%). Principals with a growth mindset tend to be open to criticism, view mistakes as part of the learning process, and value effort, although some remain constrained by fear of failure and performance orientation. The implications of this study highlight that strengthening growth mindset leadership is crucial for enabling principals to serve as role models and key drivers in implementing adaptive, innovative, and sustainable deep learning practices.
