Abstract

These community service activities were conduted at Tambak Rejo Village, Padang Jaya District, North Bengkulu Regency, towards local residences in cooperation with students from Chemistry Education Department, University of Bengkulu, April 27th, 2025. Local residences were very enthusiast with the activities which are socialization of the importance of sustanability act; cleaning activity of waste at local area, and tree restoration as an act of afforestation. These activities are aim to provide green lanscape that can prevent erotion by maintaning the balance between water system and soil strangulation. These act followed the principles of green chemistry concept toward sustainability. Tambak Rejo Village is an areal with vast open field and quite suceptible to draught in dry season. This afforestation project aim to prevent draught, as well as provide green, and beautiful landscape for local residence. These community service activities were done in several steps which are socialization towards local residence, the act of cleaning of local waste, and planting several trees in prepared land. Both local residences and students from Chemistry Education Study Program involved directly in all activities. Keywords: green chemistry, afforestation, sustainability

Abstract

This research aims to identify the physicochemical characteristics and pathogenic antibacterial activity of papaya leaf extract liquid soap (Carica Papaya L.). The sample used was papaya leaf extract whose mass was varied. The data acquisition process was obtained from the results of physicochemical testing of liquid soap formulations and from the results of antibacterial activity tests. This research began by extracting the sample using maceration technique. The extract was then formulated to be the liquid soap formulation 1, 2 and 3 with various masses i.e. three, four and five grams of extract, respectively. The physicochemical test showed that the organoleptic test, pH test, foam height test, specific gravity test, water content test and free alkali test met the SNI physical quality standards for liquid soap and the antibacterial activity test carried out on S. aureus and E. coli bacteria was obtained for S. aureus bacteria. formulations 1, 2 and 3 produce resistance of 2.06 mm, 2.21 mm and 2.46 mm respectively. Meanwhile, for E. coli bacteria, the inhibitory power produced by formulations 1, 2 and 3 was 2.84 mm, 3.41 mm and 3.71 mm, respectively. Based on the results of this research, it can be concluded that the liquid soap formulation from papaya leaf extract meets the physical standards for liquid soap quality according to SNI and has antibacterial activity.

Abstract

Students’ understanding of synthetic polymer topics was still low due to the abstract nature of the material and the lack of supporting teaching resources. This study focused on developing a project-integrated chemistry e-module on the topic, aiming to produce a valid, practical, and effective learning resource. The development model used was ADDIE, which consisted of analysis, design, development, implementation, and evaluation stages. The validation results showed that the e-module was very feasible in terms of content with a score of 94% and feasible in terms of media with a score of 73%. After revision, the media score increased to 96% with a very feasible category. A small-scale trial involving 12 students of grade XII in the 2024/2025 academic year obtained very positive responses with an average of 94%. The implementation with 27 students of grade XI IPA 1 MAN 1 Bengkulu through pre-test and post-test resulted in an N-Gain score of 0.74 (high category). These findings proved that the developed e-module was effective in improving students’ understanding and was feasible to be used as an alternative chemistry learning resource on synthetic polymers.

Abstract

This research is a research and development (R&D) that aims to produce a product in the form of a web-based digital snakes and ladders game on fundamental law in chemistry. This study aims to determine the results of feasibility reviewed by experts, student responses, and implementation results after using digital snakes and ladders game media. This research uses the ADDIE development model which includes the stages of analysis, design, development, implementation, evaluation. Response test subjects were students of SMAN 8 Bengkulu City class X-2 totaling 35 students and implementation test class X-1 totaling 35 students. The instruments used in this study include interview sheets, observation sheets, students need analysis questionnaires, validation sheets, and students response questionnaires. The results of the validation of the digital Snake and Ladder Game on fundamental law in chemistry were declared very feasible by material and media validators with an average score of 4.59 and 4.59 respectively. Students' responses to the digital Snake and Ladder Game on fundamental law in chemistry included very good criteria with an average score of 4.14. The results of the implementation of digital Snake and Ladder Game on basic chemical law material get a percentage of 82.4% which includes very good criteria. It can be concluded from the results of the study that the digital Snake and Ladder Game on fundamental law in chemistry is feasible to be applied to learning with this material.

Abstract

This study aims to improve the quality of learning in Organic Chemistry II. Based on the problems raised, the specific objective of this study is to determine the effectiveness of using molymod media assisted by the ChemDraw application in improving students' understanding of stereochemistry material in the practicum module. To determine student learning outcomes after using molymod media assisted by the ChemDraw application on stereochemistry material in the practicum module. The type of research used is an experimental method with the aim of determining the effect of a treatment on something under controlled conditions. This study uses a pre-experimental design of the one-group pretest-posttest type. Data collection techniques include interviews, observations, tests, and student response questionnaires. Based on the average N-Gain calculation, it is known that the increase in student learning outcomes obtained an average score of 0.86, which is classified as high criteria (0.70 ≤ n ≤ 1.00), so it can be said that there was a very good increase in student learning outcomes after using molymod assisted by the ChemDraw application on the organic chemistry II practicum module on the topic of stereochemistry. The practical process of stereochemistry topics using Molymod, assisted by the ChemDraw application, can encourage students to understand the concept of the material through exploration activities, visualization, and direct manipulation of molecular models. The students' response to the practical module presented in the form of an integration of the use of Molymod and ChemDraw was an average score of 91%, which is classified as very good.

Abstract

This research was a development of an electronic Student Worksheet (e-LKPD) based on the Nature of Science (NOS) on Acid-Base topics, which aimed to determine the feasibility level of the LKPD, students responses, and the improvement of students learning outcomes. The worksheet development used the ADDIE model (Analysis, Design, Development, Implementation, and Evaluation). The LKPD was validated by three expert validators, a small-scale trial involved 12 students from class XII IKM 2, whilst a large-scale trial involved 35 students from class XI IKM 2 at SMAN 7 North Bengkulu. Data collection was conducted using interview sheets, needs assessment questionnaires, validation sheets, students response questionnaires, and test instruments. The feasibility test by experts yields an average percentage of 87.27%, categorised as very feasible. Participant responses to the LKPD show an average percentage of 85%, which is in a very good category. The N-Gain score for learning outcomes is 0.43, indicating a moderate category. Based on the research results, it is concluded that the NOS-embedded LKPD on acid-base chemistry is declared very feasible for learning and improving students learning outcomes.  Keywords: Student Worksheet, Nature of Science, Acid-Base, Learning Outcomes, Development
