Abstract

Penelitian ini bertujuan untuk mengetahui tingkat kelayakan, respon mahasiswa terhadap suplemen bahan ajar bahan ajar Kimia Organik Bahan Alam (KOBA KIM 413, KD 2) dengan pendekatan STEM’S bebasis android dan hasil belajar mahasiswa  setelah menggunakan suplemen bahan ajar tersebut. Penelitian ini dilaksanakan pada bulan Februari-Juli 2020. Model yang digunakan pada penelitian pengembangan ini adalah ADDI (adaptasi dari model ADDIE) yang terdiri dari tahap analisis, perencanaan, pengembangan, penerapan. Penelitian ini dilakukan di Univeristas Bengkulu dengan subjek mahasiswa pendidikan kimia Universitas Bengkulu yang mengambil mata kuliah KOBA TA 2019/2020. Mahasiswa dengan NPM genap berjumlah 9 orang untuk uji coba skala kecil dan mahasiswa dengan NPM ganjil berjumlah 21 orang untuk  uji coba skala besar. Instrumen penelitian yang digunakan berupa angket kebutuhan, lembar validasi, angket respon, serta lembar evaluasi. Hasil penelitian ini diperoleh: (1) tingkat kelayakan suplemen bahan ajar dengan pendekatan STEM’S berbasis android, persentase kelayakan dari segi materi  yang didapat yaitu 92,86 % dengan kategori sangat layak sedangkan dari segi media yaitu 80,21 % dengan kategori sangat layak sehingga bahan ajar dinilai layak untuk diujicobakan; (2) Hasil uji coba skala kecil didapatkan respon baik dengan persentasi rata-rata 89,75% dengan ada perbaikan; (3) Hasil belajar mahasiswa setelah menggunakan suplemen bahan ajar KOBA didapatkan nilai rata-rata sebesar 57,3 yang masuk pada kategori lulus. sehingga dapat disimpulkan bahwa suplemen bahan ajar cara-cara isolasi dan identifikasi senyawa bahan alam dengan pendekatan STEM’S bebasis android yang telah dikembangkan dapat digunakan sebagai suplemen dalam proses pembelajaran KOBA

Abstract

This research is developing an integrated instrument component (KIT) practicum on buffer solution material. The study aimed to determine the feasibility level of the KIT developed and the students' response to the KIT.  The development model is carried out by using the ADDIE model (Analysis, Design, Development, Implementation, and Evaluation). The research was conducted in May 2022 at SMA Negeri 5 Kota Mukomuko. The trial class selection was conducted through purposive sampling of all XI MIPA classes, with 12 students from the XI MIPA 2 class participating in small-scale trials and 30 students from the XI MIPA 1 class in large-scale trials. Data collection methods were carried out using written tests and student response questionnaires. The data obtained were analyzed using validation tests, response questionnaire analysis, and an examination of student learning outcomes. The results obtained (1) KIT practicum is very feasible to be used as a practicum media by students based on the results of validation tests on media and material aspects, (2) The response of students to the trial of the KIT practicum of buffer solution is included in the very interesting category shown in the acquisition of an average value of 86.6%.
