Abstract

ABSTRACTImplementing entrepreneurship as part of the Merdeka Curriculum is considered suboptimal due to the numerous challenges schools face. This is consistent with the survey results among chemistry educators in the Singkawang, which showed that while most have implemented entrepreneurship in their teaching, it has not yet incorporated local wisdom and has not been included in their teaching tools. The purpose of this community service program (PKM) is to enhance educators' ability to develop entrepreneurship-based learning that incorporates local wisdom and to describe educators' responses to the training activities conducted. The method used in this PKM is a training method for 24 chemistry educators in Singkawang, consisting of three stages: preparation, implementation, and evaluation. The results of the PKM activities showed increased knowledge and helped Singkawang's chemistry educators integrate these two concepts into their teaching.Keywords: Learning Development, Entreprenuership, Local Wisdom  ABSTRAKPelaksanaan kewirausahaan sebagai implementasi kurikulum merdeka dirasa belum optimal dikarenakan terdapat banyak kendala yang harus dihadapi oleh sekolah.

Abstract

The use of synthetic dyes as color enhancers or generators has caused various environmental and health problems. Plant tannin biomordants offer an alternative solution to address these issues. The sample used in this study were Cengkodok (M. malabathricum) plants that grow wild in places that get enough sunlight such as shrubs. Phytochemical screening on various parts of the cengkodok plant revealed that the highest tannin content is found in the leaf. However, until now there has been no scientific evidence that presents differences in tannin levels in cengkodok leaf with various types of solvents. This study aims to determine the yield and total tannin content of cengkodok leaf extract obtained through maceration process using methanol, ethanol, and ethyl acetate solvents. The extract yield was determined by comparing the weight of the dry extract with the powdered cengkodok leaf material. The total tannin content was analyzed using UV-Vis spectroscopy at a wavelength of 755.8 nm with Folin-Ciocalteu reagent and sodium carbonate. Tannic acid was used as a reference. The research results showed that the yield values for Cengkodok leaf extracted with methanol, ethanol, and ethyl acetate were 5.05%, 4.72%, and 1.59%, respectively. The total tannin content of cengkodok leaf extracts with methanol, ethanol, and ethyl acetate solvents was 0.47%±0.04, 0.37%±0.01, and 0.19%±0.04, respectively. Based on this research, it can be concluded that methanol is the most effective solvent in extraction and determination of total tannin content of Cengkodok leaf extracts.

Abstract

The use of metal mordants in fabric dyeing can harm the environment and health, so it is necessary to look for natural mordants that are more environmentally friendly. The utilization of Simpur Air leaves (Dillenia suffruticosa) as a biomordant is one of the efforts to produce a more environmentally friendly tannin mordant. D. suffruticosa has been reported to contain tannin compounds in all parts of the plant. However, scientific evidence of differences in the total tannin content of methanol extracts of D. suffruticosa leaves with various extraction methods have not been found so far. This study aims to determine the effect of different extraction methods on the yield value and total tannin content of methanol extracts of D.suffruticosa leaves using UV-Vis spectrophotometric method at a wavelength of 755.8 nm with Folin Ciocalteau reagent. D. suffruticosa leaves are extracted by using three methods, namely maceration, soxhletation and reflux. Tannic acid is used as a comparator. The results show that the yield value of D. suffruticosa leaves extracted by maceration, soxhletation and reflux methods were 8.35%; 12.26%; and 25.24%, respectively. The total tannin content of methanol extract of D. suffruticosa leaves with maceration method is 0.15% ± 0.007; soxhletation is 0.18% ± 0.007 and reflux is 0.21% ± 0.016.  Based on the results of the data analysis, the significance value <0.05 was obtained. It can be concluded that the extraction method affects the yield value and total tannin content of methanol extract of D. suffruticosa leaves.

Abstract

The industrial revolution 4.0 makes us develop into adaptive humans. 21st century skills, that involves thinking critically and inventiveness, abilities to communicate and teamworks, are needed to adapt to all technological changes. Among the four 21st century skills, creative thinking skills are needed to develop innovative ideas in answering problems in the learning process. The variable of this research is students’ creative thinking skills. The aspects studied consist of originality, fluency, flexibility, and elaboration. The research process was conducted with descriptive quantitative using a sample of 35 students of class XI IPA at SMA Negeri 1 Mempawah Hilir. The research instruments used were creative thinking test questions in the form of descriptions and interview guidelines. The results of data analysis stated that students’ creative thinking skills were included in the insufficient category with a percentage of 74,29% of the sample. The average value in originality is 42,68%, while the aspects of fluency, flexibility, and elaboration have the same average of 36,78%. Several factors cause the low level of students’ creative thinking skills; namely students still memorize the material in the book, lack of learning experience, students tend to give answers as they are because they think they will get a score even though they only write a few answers, and another factor is that students lack focus when working on test questions.
