Abstract

Green chemistry is an alternative solution that can be used by chemistry teachers for safe and environmentally friendly chemistry experiments in schools. This community service aims to provide training to high school/vocational high school chemistry teachers in Ogan Ilir Regency, South Sumatra to carry out simple practical activities based on green chemistry. This service activity consists of 3 main stages, namely the preparation stage, the implementation stage and the evaluation stage. The target audience for this community service activity are 24 high school chemistry teachers from Ogan Ilir, South Sumatra. And furthermore, it is hoped that chemistry teachers who attend training can guide their chemistry teacher colleagues in their place. There are 7 simple green chemistry-based practical procedures collected from this service activity. The simple green chemistry-based practicum procedures are: 1) Redox reactions; 2) Making Binahong Covid-19 Herbal Soap; 3) Factors Affecting Reaction Rate; 4) Colloid-Tofu Making; 5) Colloids - Clumping (Coagulation) of Colloidal Particles; 6) Combustion of carbon compounds (complete and incomplete combustion); 7) Freezing Rubber Sap Using Pineapple Peel Extract. Overall, the target audience has been trained to make simple practical procedures based on green chemistry. This can be seen from the materials and practicum procedures that are in accordance with the basic principles of green chemistry, namely environmentally friendly, reducing environmental pollution, not classified as hazardous materials.

Abstract

Research Development of group VIIIA and zeolite elemental chemistry teaching materials and problem based learning (PBL) aims to produce valid, practical and effective PBL-based teaching materials. This research is a development research with ADDIE development model combined with Tessmer formative evaluation. The stages of ADDIE development used in this study include the analysis stage, the design stage, and the development stage only, which then proceeds to the Tessmer formative evaluation stage which includes expert review, one to one, small group, and field test. At the expert review stage, PBL-based teaching materials were validated by experts from the field of pedagogic experts with an average score of 1 (high), material experts with an average score of 1 (high) and design experts with an average score of 0.933 (high). The results of the validation assessment scores obtained at the expert review stage were 0.978 (high). This shows that the PBL-based teaching materials that have been developed are valid. The practicality of PBL-based teaching materials is seen from the results of questionnaires and respondents' comments on PBL-based teaching materials with a Cronbach's Alpha value at the one to one stage of 0.800 (very high) and at the small group stage of 0.727 (high) which means PBL-based teaching materials have been practically developed. The effectiveness of the PBL-based teaching materials that have been developed can be seen from the learning outcomes test at the field test stage with an N-gain score of 0.84 in the high category. This shows that the PBL-based teaching materials that have been developed are effective. It can be that the PBL-based teaching materials that have been developed have met the valid, practical, and effective criteria.Keywords: Development research, Problem based learning (PBL) teaching materials, Elemental chemistry of group VIII A and zeolite.

Abstract

This development research aims to develop wood and pulp chemicals in wood and fiber morphology as supplementary teaching materials for students of the Chemical Education study program at Sriwijaya University using the 4STMD (Four Step Teaching Materials Development) method. The steps of the 4STMD method, namely the first stage is the selection stage, carried out by analyzing needs, curriculum and analyzing the material by looking for references in various sources. The second stage, namely the structuring stage, is carried out by adding or subtracting material and compiling the material. The third stage is the characterization stage, carried out by developing the results of material analysis. The fourth stage is the didactic reduction stage, but the researcher did not carry out the didactic reduction stage. Data collection techniques used in the form of interviews, pre-research questionnaires and validation questionnaires. In the material validation test, the validity of teaching materials was obtained based on the Aiken coefficient of 0.75 which was categorized as high. Based on these results, it shows that the development of wood and pulp chemicals in wood sub-materials and fiber morphology has met the valid criteria.

Abstract

This study aims to determine the effectiveness of the main group elemental chemistry textbooks based on problem based learning in improving student learning outcomes. The design of this study was a quasi-experiment with one group pretest-posttest design. The participants in this study were sixth year chemistry education students at Universitas Sriwijaya for the 2021/2022 academic year. Test instruments was implied in this research and analyzed using statistics with N-gain data. The results showed that problem-based learning teaching materials for chemistry education students were categorized as very effective with a high level of N-gainKeywords: chemistry textbooks, problem-based learning, chemistry learning outcomes.DOI: http://dx.doi.org/10.23960/jpmipa/v23i4.pp1376-1381
