Abstract

Wood is one of several materials that is very useful for man, even wood with less quality tends to be used more. Anthydride-acetic has been used to improve the wood quality by improving the stability of wood dimension. This research studied about the influence of anhydride-acetic on wood molecular structure by studying the change of wood performance, functional group with FTIR method, bound water with DSC method, dimensional stability by determining ASE, and degree of crystallinity with XRD method, on the condition of 110 oC, 15% as long as 24 hours for Pinus merkusii. It is concluded that dimensional stability increase of Pinus merkusii through acetylation, is indicated by the changing of – OH group of wood components with the bigger acetyl group causing amorf region increase. This condition enabled the swelling of wood volume. The substitution of –OH group to a bigger acetyl group caused the steric hindrance which decrease the molecular move of wood component. Therefore, both the swell and the shrink of wood cell walls volume became more difficult, that the swelling of Pinus merkusii volume was smaller or dimensional stability of Pinus merkusii increased.

Abstract

Durian (Durio zibethinus) originally was wild plants from forests of Malaysia, Sumatera, and Borneo. Durian trees cultivated Indonesian society is primarily not for timber, but to produce fruit. At the season of durian, durian rind becomes waste. A tropical plant product which is unfortunate if the durian rind that contains a lot of fiber disposed of as trash, as long as this happens. Has conducted research utilization fiber of durian rind in the field of coal energy. Durian rind fibers can act as a stimulant ignition of coal. Durian rind fibers in various positions with coal and other material added form a briquettes. The position of the fibers has been investigated: briquettes with fiber outer position (1), lower (2), the side (3), the top-down (4), and two quarters (5). Briquettes with durian serat kulit different positions have different speeds and long flame.Keywords: fibre, durian rind, coal ignition, flame speed, long burning

Abstract

The Socialization Program of Self-Token Economy Techniques was carried out at the Muhammadiyah Nuruddin Orphanage with the main goal of increasing the academic motivation of orphanage children through a token-based reward system approach. Children in orphanages often face challenges such as low motivation to learn, lack of incentive systems, lack of confidence, and an unconducive learning environment. To answer these problems, this program prioritizes the Self-Token Economy technique as an educational and applicative intervention strategy. The implementation method consists of the preparation stage, the implementation of socialization, and impact evaluation. The target of the activity was 15 orphanage children who were actively involved in the entire series of programs. This activity also involves strategic partners who play a role in providing facilities, technical assistance, and program sustainability planning. The results showed an increase in participants' academic motivation, characterized by increased participation in learning activities, understanding of the award system, and the emergence of independent learning initiatives. In addition, this program produces outputs in the form of scientific publications as a form of dissemination of knowledge and good practices in developing the academic motivation of orphanage children. In conclusion, the Self-Token Economy technique has proven to be effective as a social intervention approach that can be applied in the orphanage environment to support the achievement of children's education more optimally.

Abstract

The Baayun Counseling Socialization Program at the Health Center is designed to improve the understanding and skills of health workers in implementing a more humane and local culture-based counseling approach. Baayun counseling is a therapeutic communication method that integrates cultural values in the interaction between health workers and patients, so that services become more personalized, empathetic, and meaningful. This program is carried out through several stages, namely needs analysis, socialization, and effectiveness evaluation. The main target is health workers in primary services who interact directly with patients. The expected results of this program include improving the competence of health workers in understanding and implementing Baayun Counseling, as well as increasing patient satisfaction and compliance with health services. Program evaluations show that this approach is able to create positive changes in communication patterns, strengthen the relationship between health workers and patients, and improve the overall quality of counseling services. By adopting Baayun Counseling, Puskesmas can strengthen the cultural dimension in health services, making them more relevant and responsive to the needs of local communities. The program also has the potential to be replicated in other culturally rich regions as part of a community-based health service quality improvement strategy.
