“…Kata Kunci: aldehida dan keton, belajar online, keaktifan belajar, kimia organik, pendekatan MIKiR distimulasi keaktifan selama kegiatan pembelajaran, terlebih lagi untuk membangun keaktifan secara berkelompok di antara mahasiswa (Laksono, 2018). Kerumitan pada konsep-konsep kimia organik, khususnya pada konsep senyawa aldehida dan keton, terlebih lagi dengan pelaksanaan perkuliahan secara daring, maka dibutuhkan suatu konsep perkuliahan yang dapat memfasilitasi keaktifan mahasiswa dalam mengikuti perkuliahan, dan bagi dosen dapat menjadi media yang menjadi solusi permasalahan yang dihadapi pada perkuliahan kimia organik (Clark et al, 2020;Kaanklao & Suwathanpornkul, 2020;Mulyanti et al, 2019). Salah satu alternatif yang dapat diimplementasikan dalam kegiatan perkuliahan adalah denga Pendekatan MIKiR (Mengalami, Interaksi, Komunikasi, Refleksi) (Siregar dan Sari, 2020).…”

“…Akhir dari sesi aplikasi (aplikasi 3), mahasiswa dibagi secara berkelompok (3-4 orang perkelompok) untuk mengerjakan lembar kerja (LKM) (Chang et al, 2018;Horowitz et al, 2013;Mulyanti et al, 2019), dengan LKM yang berbedabeda antara kelompok satu dengan kelompok lain. Diskusi kelompok dilakukan secara daring dan masing-masing kelompok diberikan room google meet.…”

Organic chemistry course is a compulsory subject for chemistry education students. One of the main points of discussion is aldehyde and ketone compounds including the concept of structure, numbering, and nomenclature. With a pandemic condition that demands online lectures, the research team is trying to implement the MIKiR approach online as a solution to making organic chemistry courses interesting, student-centered, and able to achieve learning goals very well. A series of activities with the MIKiR approach have been carried out including introduction, connection, application, and reflection. The results of the evaluation showed that students mastered the concepts of aldehyde and ketone compounds very well with an average value of 80-100%, through a multiple choice test with google form media. After the implementation of the implementation of the MIKiR approach, students were given a questionnaire related to the implementation of lectures, the results of the questionnaire included 59.28% agreeing responses, 32.13% strongly agree, and 8.59% disagree with the implementation of the MIKiR approach in organic chemistry lectures. It can be concluded that the MIKiR approach can be recommended for lecturers in carrying out organic chemistry courses online.

“…Hal-hal penting yang harus dipertimbangkan dalam pelaksanaan praktikum adalah persiapan mahasiswa, selanjutnya adalah pembuatan diagram alur praktikum, kerja tim selama praktikum, yang terakhir adalah metode penulisan laporan hasil praktikum (Mulyanti et al, 2019). Ketika penulisan laporan, mahasiswa diarahkan untuk membiasakan ide dari apa yang sudah mereka lakukan dan pelajari, serta kejujuran yang tak tidak dapat diabaikan tentang apa yang telah terjadi selama praktikum (Mulyanti et al, 2019).…”

“…Selama ini, kegiatan pembelajaran di laboratorium belum secara maksimal meningkatkan pemahaman konsep mahasiswa (Sukmawati et al, 2020). Khususnya pada konsep kimia organik, meski mahasiswa sudah menempur perkuliahan praktikum kimia organik (Mulyanti et al, 2019). Terlebih lagi, konsep dasar kimia organik sejatinya menjadi pengetahuan dasae bagi mahasiswa calon guru kimia, sebagai bekal saat kelak mengajar (Angelini & Gasbarri, 2018).…”

IMPLICATION OF MINI PROJECT ORGANIC CHEMISTRY EXPERIMENTS FOR IMPROVING ORGANIC CHEMISTRY CONCEPTAbstractOrganic Chemistry Practice is one of the courses in the chemical education department that must be taken by pre-service teacher of chemistry, still lack of mastery of students on organic chemistry concepts, requiring lecturers to be able to design the experiment in such a way so as to increase mastery of the concept of organic chemistry students in Organic Chemistry Practice. This study aims to apply the mini project model to the Organic Chemistry Practice so that it is expected to increase students' mastery of concepts in organic chemistry. The research was conducted using quantitative methods, its measuring conceptual change from the students from N-gain score. The results showed that there was an increase in students' mastery of concepts based on the% N-gain obtained. The majority of students are at a high criterion with% N-Gain> 70. The t test shows the significance of the implementation of the mini project model to increase students' mastery of concept concepts.AbstrakRendahnya penguasaan mahasiswa terhadap konsep-konsep kimia organik, menuntut pengajar untuk dapat mendesain praktikum sedemikian rupa, sehingga dapat meningkatkan penguasaan konsep kimia organik mahasiswa pada Praktikum Kimia Organik. Penelitian ini bertujuan untuk menerapkan model mini project pada Praktikum Kimia Organik sehingga diharapkan dapat meningkatkan penguasaan konsep mahasiswa pada materi kimia organik. Penelitian dilakukan dengan metode kuantitatif, yakni mengukur hasil tes penguasaan konsep mahasiswa. Hasil penelitian menunjukkan bahwa terjadi peningkatan penguasaan konsep mahasiswa berdasarkan hasil %N-Gain yang diperoleh. Mayoritas mahasiswa berada pada kriteria tinggi dengan %N-Gain > dari 70. Uji t menunjukkan signifikansi pelaksanaan model mini project terhadap peningkatan penguasaan konsep mahasiswa.

This case study aims to identify chemistry education students' perspectives on attitudes and implementation of the principles of green chemistry during the COVID-19 pandemic. The participant of this study was 64 chemistry education students who, from the beginning, have conducted online learning, including practicum. The instrument of this research was an online questionnaire to gain the required information. The data were analyzed using NVivo 12 software and presented in percentages based on 12 principles of green chemistry: (1) potential waste generation reduction, (2) efficient use of raw materials, (3) application of environmentally safe production methods, (4) environmentally friendly chemicals, (5) safer additives, (6) minimal use of heat, (7) natural ingredients, (8) reaction products with minimal by-products, (9) the use of effective catalysts, (10) easily biodegradable products for the environment, (11) time management of hazardous products, and (12) anticipation for physical contact with hazardous materials. Moreover, 85% of the students agree that the 12 th principle must be well applied. The research findings serve a discourse for lecturers to convince the students to understand and implement the principles of green chemistry in practicum activities, especially during the pandemic.
