Pemahaman mahasiswa terhadap materi perkuliahan dipengaruhi oleh media dan sumber belajar yang digunakan. Kurangnya kemampuan menganalisis dan penalaran terhadap materi yang diajarkan khususnya perkuliahan kimia dasar menimbulkan rendahnya kemampuan berpikir kritis mereka. Mahasiswa kesulitan dalam menggunakan dan menginterpretasikan berbagai jenis representasi kimia (misalnya, menggambar atau menafsirkan struktur; menetapkan nama berdasarkan rumus struktur, dan menganalisis struktur). Penelitian ini bertujuan untuk mengembangkan modul pembelajaran kimia berbasis multipel representasi pada materi kimia dasar yaitu stoikiometri. Penelitian ini merupakan penelitian R&D yang mengadopsi pengembangan dari Borg & Gall. Pengambilan sampel menggunakan purposive sampling. Penelitian ini dilaksanakan di kota Langsa bertempat di Ruang Kelas Belajar Prodi Pendidikan Kimia dari bulan Februari 2019 sampai Agustus 2019. Sampel yang digunakan adalah mahasiswa tingkat I atau semester II dengan pertimbangan kelas hanya terdiri dari satu unit dan materi stoikiometri hanya ada pada perkuliahan kimia dasar semester II. Pengumpulan data menggunakan angket dan tes. Analisis data menggunakan analisis data skala likert. Hasil penelitian ini yaitu nilai kevalidan modul sebesar 90,5% ahli materi, dan ahli media sebesar 91,5%; kepraktisan modul dilihat dari angket respon siswa sebesar 87,17 dan 86,89; serta nilai keefektifan modul dilihat dari nilai ketuntasan belajar siswa sebesar 80,4%. Berdasarkan hasil penelitian yang diperoleh disimpulkan bahwa modul yang dikembangkan telah layak, praktis dan efektif digunakan dalam proses pembelajaran.

This study aims to analyze the effect of feedback from local content-based practicum modules on students' science process skills. Research subjects for product trials developed in this study were students of class XI using a purposive sampling technique with a sample size of 60 students. The method used in this research is quasi-experimental (quasi-experimental). The research instrument was a feedback rubric on applying a local content-based practicum module, observation sheets, and tests on the results of Science Process Skills (KPS). Data processing and analysis is carried out by comparing the initial and final science process skills scores by looking at the science process skills N-Gain score. Hypothesis testing uses the T-test to apply a local content-based practicum module on science process skills by analyzing the initial and final science process skills scores. The highest percentage result lies in the indicator of planning an experiment or investigation and using experimental tools and materials, namely 90%. There is a difference between a class that implements a local content-based practicum module and is given feedback with a class that uses a regular module for each class. The experimental class had an N-gain value of 0.75 or in the high category, while the control class had an N-gain value of 0.64 or in the moderate category. There are differences in students' Science Process Skills (KPS) using local content-based practicum modules with conventional practicum modules.
