Abstract

Most of the chemistry learning processes emphasize concepts and formula. This then makes students judge that the concept of chemistry is a concept that is difficult to understand because it is abstract and the lack of application of theory through direct practicum, especially for schools which are limited with practicum facilities and infrastructure, so that this can reduce students' motivation and interest in learning chemistry. Not only that, students' knowledge and perceptions of viewing chemistry are also always negative and dangerous and can pollute the environment. So this triggers stigma or suspicion of symptoms of chemophobia in students. So the need for practical activities or demonstrations in the process of implementing learning through simple experiments according to pre-arranged procedures in order to make it easier for abstract chemical theoretical concepts to become real. So that from these activities, students can develop their scientific attitude through the problem solving process presented and increase student activity, interest and learning outcomes in the chemistry learning process. Therefore, in order for the practicum to go well, a practicum worksheet is needed as a learning medium which contains a set of basic activities that are systematically arranged and sequenced by students to help maximize understanding. One of the learning models with the help of LKP teaching materials is the Project Based Learning model by applying the Green Chemistry aspect which can be applied to one of the chemical topics, namely acids and bases. The developed practicum worksheet is a worksheet that is arranged based on the syntax format of the Project Based Learning learning model by applying aspects of Green Chemistry contained in the form of materials and applications through chemistry practicum. The method used in this electronic LKP development research is the Research and Development method with a 3D procedural model modified by S.Thiagarajan's 4D model (1974). The data collection technique was carried out using a validity test instrument which was analyzed based on the Aiken's V 0.75 formula with a total of 8 media and material experts validators which resulted in an average value for the media validity test of 0.85. While the average value of the material validity test is 0.87. The results showed that the LKP developed was feasible to use and got a good response from the results of the student response questionnaire analysis, which was 95% in the very good category.

Additional Information:	Sebagian besar proses pembelajaran kimia menekankan pada konsep dan rumus. Hal ini kemudian membuat peserta didik menilai bahwa konsep kimia merupakan konsep yang sulit difahami karena bersifat abstrak serta kurangnya penerapan aplikasi teori melalui praktikum secara langsung khususnya bagi sekolah yang terbatas dengan sarana dan prasarana praktikum, sehingga hal ini dapat menurunkan motivasi dan minat peserta didik terhadap pembelajaran kimia. Tidak hanya itu, pengetahuan dan persepsi siswa memandang kimia juga selalu negatif dan berbahaya serta dapat mencemari lingkungan. Sehingga hal ini memicu stigma atau dugaan adanya gejala chemopobia pada siswa. Maka perlunya kegiatan praktik atau demonstrasi dalam proses pelaksanaan pembelajaran melalui percobaan sederhana sesuai prosedur yang telah disusun sebelumnya agar dapat memudahkan konsep teori kimia yang bersifat abstrak menjadi nyata. Sehingga dari kegiatan tersebut, peserta didik dapat mengembangkan sikap ilmiahnya melalui proses pemecahan masalah yang disajikan dan meningkatkan aktivitas, minat serta hasil belajar siswa dalam proses pembelajaran kimia. Oleh karena itu, agar praktikum berlangsung dengan baik maka dibutuhkan lembar kerja praktikum sebagai media pembelajaran yang berisi sekumpulan kegiatan mendasar yang tersusun secara sistematis dan urut yang dilakukan peserta didik untuk mmbantu memaksimalkan pemahaman. Salah satu model pembelajaran dengan bantuan bahan ajar LKP yaitu model Project Based Learning dengan menerapkan aspek Green Chemistry yang dapat diterpakan pada salah satu topik kimia yaitu asam-basa. Lembar kerja praktikum yang dikembangkan ini merupakan lembar kerja yang disusun berdasarkan format sintak model pembelajaran Project Based Learning dengan menerapkan aspek Green Chemistry yang dimuat dalam bentuk materi dan aplikasi melalui praktikum kimia. Metode yang digunakan pada penelitian pengembangan LKP elektronik ini yaitu metode Research and Development dengan model prosedural 3D hasil modifikasi model 4D dari S.Thiagarajan (1974). Teknik pengumpulan data dilakukan dengan instrumen uji validitas yang dianalisis berdasarkan rumus Aiken’s V 0,75 dengan junlah validator sebanyak 8 ahli media dan materi yang menghasilkan rata-rata nilai untuk uji validitas media sebesar 0,85. Sedangkan rata-rata nilai uji validitas materi sebesar 0,87. Hasil penelitian menunjukkan LKP yang dikembangkan layak untuk digunakan dan mendapatkan respon yang baik dari hasil analisis angket respon siswa yaitu sebesar 95% dengan kategori sangat baik.
