Abstract

The use of synthetic dyes in the textile industry has a negative impact on the environment. Therefore, it is necessary to explore natural dyes that are more environmentally friendly. The aim of this research is to find natural dyes from Acalypha siamensis leaves. In this research, compounds contained in A. siamensis extract were identified using FT-IR and GC-MS instruments, then simulations were carried out of the reactions that occurred between cinnamaldehyde (E), cellulose in cotton, and alum mordant using quantum chemistry software. ORCA 5.0.2 and Visual Molecular Dynamics (VMD). The cinnamaldehyde compound is the main constituent compound in A. siamensis leaf extract. Based on the simulation results: the reaction between cinnamaldehyde (E), cellulose in cotton fabric, and alum mordant is energetically favorable. The reaction simulation results are in line with experimental research, the reaction of cellulose in cotton fabric, alum mordant, and cinnamaldehyde produces a brownish green color. A. siamensis leaves have potential as a dye in eco-prints.

Abstract

This study examines the effect of an integrated teaching model that combines Flipped Classroom, Authentic Learning, and Ignatian Pedagogy. The study was conducted to observe the learning motivation of Biology Education students in Biosystematics, specifically addressing the topic of “The Role of Biosystematics in Research.” A mixed-methods approach with a Convergent Parallel design was implemented to obtain the quantitative and qualitative data. The quantitative data were collected through a learning motivation questionnaire using a 6-point Likert scale, and the qualitative data were gathered from open-ended questions to support the analysis of the quantitative data. The results show a high average motivation score from 5.37-5.40, with 82.86% to 97.14% of respondents choosing scores 5 and 6 for each item. These findings show that the integrated teaching model encourages engagement through intrinsic reflection and commitment to being morally responsible. Qualitative data reveal that students had been able to experience meaningful learning within real-world contexts, so they felt challenged to be morally responsible. In conclusion, the integrated model supports learning motivation by acting on character development through Ignatian Pedagogy as well as the 4C values (Competence, Conscience, Compassion, and Commitment).­

Abstract

Biology education in secondary schools faces challenges in implementing practical work that is relevant to the learning material, one of which is biotechnology. Musyawarah Guru Mata Pelajaran (MGMP) Kota Yogyakarta, or the Yogyakarta Biology Teacher Working Group, has identified an urgent need for training in a biotechnology experiment that is simple, applicable, and takes place in the context of school and community learning. This Pengabdian kepada Masyarakat (PkM) or Community Service Activities provided an innovative solution in the form of applicable kombucha-making training for biotechnology-supported practical learning. The goal of this activity was to improve the Biology Teacher Working Group's ability to implement appropriate kombucha-making training to support the biotechnology learning experience. This activity was carried out using a training method. The training participants were 22 teachers from 10 schools around Yogyakarta. The implementation of the training included delivering materials, practicing making kombucha, and collecting data. The data collection instruments included test questions and questionnaires. The PkM activity of simple biotechnology practical training through making kombucha for the biology teachers of MGMP Kota Yogyakarta was successfully implemented following the objectives, namely improving the teachers’ competence in terms of knowledge and skills, especially in carrying out biotechnology experiments. The teachers' training provided them with theoretical and practical knowledge about making kombucha, as well as kombucha's benefits, which could be applied in the contexts of education and society. The training also met the partners' expectations, specifically by providing alternative practical themes that were part of the learning materials and could be implemented in schools with limited resources. The next step in this PkM activity is to collaborate with MGMP partners to organize simple and applicable practical training, so that the training's impact is greater. Practical training can be a way for universities to help teachers improve their skills.
