Abstract

Intermolecular forces are one of the topics in basic chemistry. Intermolecular forces consist of abstract concepts that require multiple representations (macroscopic, submicroscopic, and symbolic) to visualize those concepts. Moreover, the multiple representations are needed to help students understand the abstract concepts of intermolecular forces. Multiple representations were presented as pictures, diagrams, and animation in the videos. The aims of this research are to develop a video of intermolecular forces based on multiple representations and to determine the level of validity and student’s responses to the video. This study employs the 4D method formulated by Thiagarajan which consist of 4 stages. However, this study only adopted 3 stages; define (to know the problem), design (manufacture of product to solve the problem), and development (to determine the level of validity and student responses). The instruments used in this study were the validity and the response questionnaires. Data collected were then analyzed using the percentage criteria proposed by Riduwan. The video provides the conceps and real-life example of the London forces and hydrogen bonding. Video validation shows the level of subject matter validity is 95,38%, media validity is 98,89%, and language validity is 91,11%, where all the aspects were very valid criteria. Every aspect is validated by 3 experts. Student responses on a limited scale by 7 students show a percentage of 87,8% and a large scale by 20 students of 88,9% with very good criteria. Based on the result, the video can be used in the study of intermolecular forces

Abstract

The integration between the three levels of chemical representations is needed by students to get a comprehensive understanding. Based on the preliminary study only 45.5% out of 120 year 2 and year 3 students of chemistry education who passed the final exam with satisfactory category. Thus, teaching resources that integrate the three levels of chemical representation are needed. The aim of this study is to develop and determine the level of validity of e-module utilizing multiple representations of molecular shapes based on VSEPR theory using augmented reality technology. This research employs research and development refers to the instructional design of the ADDIE model consist of 5 stages: Analyze, Design, Develop, Implementation and Evaluation. The products of this research are the e-module of molecular shapes based on VSEPR theory utilizing multiple representations and Augmented Reality Molecule Simulator (ARMOR) application. The resources presented 13 types of molecular shapes, molecules with lone pair and without lone pair of electrons around the central atom. The instrument used in this study is the validity questionnaire sheet. Data collected were then analyzed using the percentage criteria proposed by Akbar. The results of the experts’ validation indicated that the product is categorized as very valid with 94% of content validity, 93% of media validity, and 99% of language validity. Therefore, the ARMOR is suitable for use in teaching and learning process. Students show a positive response to the use of the application in helping them understand concepts, which are easy to use, has an attractive appearance, and fun.

Abstract

This study aims to describe the 54critical thinking skills of class X science students of SMAN 2 Pontianak, Panca Bakti High School and SMAN 5 Pontianak in Stoichiometry material. This form of research uses descriptive qualitative research. The research sample was students of class X IPA of SMArN 2 Pontianak, Panca Bakti and SMAN 5 Pontianak, totaling 84 students. Students' criticaae8l thinking skills are measured using written tests in the form of essays, and unstructured interviews. The research instrument was validated using the Gregory test matrix. The results obtained that the critical thinking skills of class X science students of SMAN 2 Pontianak, SMAS Panca Bakti, and SMAN 5 Pontianak are classified as less skilled. This is indicated by the low average percentage of students' critical thinking skills of 2.4836 or 62.09%. This proves only a small proportion of students who have critical thinking skills of students on stoichiometry material.

Abstract

Mahasiswa Pendidikan Kimia merupakan mahasiswa calon guru, yang bukan hanya harus terampil mengajar tetapi diharapkan dapat menjadi insan-insan yang memiliki kemampuan wirausaha. Salah satu produk yang bisa dikembangkan untuk berwirausaha adalah sabun. Bisnis sabun dari minyak jelantah memiliki manfaat yang besar, selain memberikan keuntungan finansial juga dapat menyelesaikan masalah lingkungan dan kesehatan  yang bisa diakibatkan oleh minyak jelantah. Kegiatan Pengabdian Kepada Masyarakat ini bertujuan untuk meningkatkan pengetahuan mahasiswa terkait dengan minyak jelantah dan potensinya sebagai bahan baku untuk pembuatan sabun dan meningkatkan keterampilan mahasiswa dalam pembuatan sabun dari minya jelantah. Kegiatan pengabdian masyarakat dilakukan melalui beberapa tahap, yaitu Observasi terkait  penggunaan minyak jelantah, persiapan pelaksanaan PKM, pelaksanaan PKM, dan monitoring, evaluasi serta tindak lanjut.  Hasil observasi terkait penggunaan minyak jelantah menunjukkan bahwa lebih 50%  minyak jelantah dibuang ke lingkungan, hanya sebagian kecil saja yang diolah. Responden  kesulitan mengolah  karena keterbatan alat dan bahan serta kesulitan menghilangkan bau yang tidak sedap.  Pengetahuan tentang cara   menghilangkan bau tengik minyak jelantah, pengaroma yang cocok, dan  prosedur yang tepat untuk pembuatan sabun dari minyak jelantah diinginkan oleh peserta dalam rangka mengolah minyak jelantah menjadi sabun. Pengamatan selama kegiatan pelaksanaan sosialisasi dan pelatihan pembuatan sabun dari minyak jelantah  menunjukkan bahwa peserta sangat antusian mengikuti kegiatan.  Sebanyak 80% peserta menyatakan pelatihan yang dilakukan sangat bermanfaat sehingga mereka berkiinginan untuk memproduksi sendiri sabun dari  minyak jelantah. Diharapkan melalui kegiatan ini dapat menumbuhkan jiwa sainspreneur mahasiswa dan dapat mengatasi permasalahan yang diakibatkan oleh minyak jelantah

Abstract

The problem that arises in this study is that the assessment carried out by the teacher takes a relatively long time because of the manual calculation of points.  Then the teacher tends to make the same questions for all students, it makes it easier for students to collaborate. This study aims to determine the feasibility of an online evaluation tool using wondershare quizcreator on molecular shape materials. The form of this research is research and development (R&D) based on the steps of the ADDIE development model. The online evaluation tool using Wondershare Quizcreator on molecular shape material has been tested for feasibility by experts, including the feasibility of the material, language, and graphics. The expert feasibility test results show that the developed online evaluation tool is categorized as very feasible. This feasibility is viewed from the results of the validation of the feasibility of the material by 95.6%, the feasibility of language by 90.63%, and the feasibility of graphics by a percentage of 94.64%.
