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.

Abstract

The Sustainable Development Goals (SDGs) present new challenges in global competition. This has been reflected in the Merdeka Curriculum, which incorporates green chemistry materials and project-based learning models. However, the lack of project-based learning module has become a significant obstacle in implementing this curriculum in schools. This research aims to determine the quality of the green chemsitry module that was developed. The product development follows the ADDIE model, though the research only covers the development stage. The initial product was reviewed by 6 experts to assess its quality. A Likert-scale questionnaire was used as the evaluation instrument, consisting of four components with a total of 33 statements. Meanwhile, the user response instrument consisted of 12 statements. The results showed that the project-based green chemistry module was deemed feasible for implementation in learning. This was evidenced by the ideal percentage from the product feasibility assessment by experts at 95.95%, which falls into the Very Good category. Furthermore, the small-scale trial results indicated an ideal percentage of 82.58% categorized as Good. This module supports the implementation of SDGs in reducing environmental pollution, as it includes several projects that students can apply in waste management.

Abstract

Micro, Small, and Medium Enterprises (MSMEs) play a strategic role in the national economy, including in Kapuas Regency, Central Kalimantan, which is dominated by the culinary sector. However, most MSME owners have not yet obtained halal certification due to limited understanding, lack of access to information, and the perception that the certification process is complicated. This community service program aimed to improve MSME owners’ awareness, knowledge, and technical capacity in obtaining halal certification through the self-declare scheme. The service method employed a participatory and mentoring-based approach, implemented through structured stages consisting of preparation, implementation, and evaluation. The preparation stage involved coordination with local stakeholders, identification of MSME needs, and participant registration. The implementation stage consisted of material delivery using lectures and discussions to enhance awareness of the importance of halal certification, followed by hands-on technical assistance in using the official online halal certification system. Participants were also guided through a simple internal audit of production processes to ensure compliance with halal standards. The evaluation stage was conducted using questionnaires and direct observation to measure participants’ satisfaction, understanding, and ability to independently complete the halal certification registration process. A total of 37 culinary MSME participants successfully completed the halal certification registration through the self-declare scheme. Evaluation results indicated that the program was highly beneficial, with an average participant satisfaction rate exceeding 80%. Furthermore, the program increased MSME owners’ awareness of halal certification as a guarantee of product quality and a strategic tool for enhancing business competitiveness. Overall, this community service program successfully strengthened MSME capacity in utilizing digital-based halal certification systems and supported the development of a more competitive halal MSME ecosystem in Kapuas Regency.
