This study contains an analysis of the Student Worksheets contained in the high school textbook / used by teachers in schools, with the aim of providing information, education or solutions to problems that have arisen in practical activities. Practicum activities are an important part of science education, so they are required to create more meaningful practicum activities. In making practicum activities more meaningful and achieving goals in accordance with Basic Competencies, one of them is by reconstructing the Student Worksheet (LKPD). This study is included in the descriptive qualitative, in which LKPD cell structure and function are made as research subjects with a sample number of 5 LKPD that refers to the SBC and Curriculum 2013. The instrument used in this research refers to: first, the form of analysis of laboratory activities where problems are emerges namely in terms of conceptual (practicum activities not in accordance with the curriculum), practical (the object does not appear clearly because the procedure is less precise) and knowledge (questions that do not construct knowledge). Second, referring to the Vee Diagram developed from Novak & Gowin. The problems that arise include practical aspects which include procedures / work steps, questions that lead to the results of the practicum. therefore there is a need to reconstruct LKPD so LKPD can be well understood and achievement in accordance with the Basic Competition (KD). Abstrak. Penelitian ini berisi tentang analisis terhadap Lembar Kerja Peserta Didik yang terdapat pada buku SMA/yang digunakan oleh guru di sekolah, dengan tujuan untuk memberikan informasi, edukasi atau solusi terhadap masalah yang selama ini muncul dalam kegiatan laboratorium. Penelitian ini termasuk ke dalam deskriptif kualitatif, dimana LKPD struktur dan fungsi sel di jadikan sebagai subjek penelitian dengan jumlah sampel 5 LKPD yang mengacu pada KTSP dan Kurikulum 2013. Instrumen yang digunakan dalam penelitan ini mengacu pada: pertama, form analisis kegiatan laboratorium dimana permasalahan yang muncul yaitu dari segi konseptual (kegiatan praktikum tidak sesuai dengan kurikulum), praktikal (objek tidak mucul secara jelas karena prosedurnya kurang tepat) dan pengetahuan (pertanyaan yang tidak mengkontruksi pada pengetahuan). Kedua, mengacu pada Diagram Vee yang dikembangkan dari Novak & Gowin. Adapun masalah yang muncul diantaranya dari segi praktikal yang meliputi prosedur/langkah kerja, pertanyaan yang mengarah ke hasil praktikum. maka dari itu perlu adanya rekontruksi LKPD agar LKPD dapat di pahami dengan baik serta pencapaian sesuai dengan Kompetesi Dasar (KD).

Oftentimes the increase in industrial development is the cause of environmental problems. Environmental problems can be overcome by the presence of humans who care about the environment or have environmental literacy skills. Environmental literacy skills can be instilled from an early age, for example through practicum learning in schools. However, considering that the Covid-19 pandemic is one of the obstacles in carrying out the practice, virtual laboratory-based online learning is carried out. This study was aimed to improve students' environmental literacy through virtual laboratory-based online learning that has been developed.  This research is quasi experiment with pre-test and post-test research design Control Group Design. The total sample of the study was 70 students of class X at state senior high school. The research instrument used was in the form of test questions about environmental changes material and environmental literacy questionnaires. The results showed that the N-gain value of environmental literacy in the experimental class was 29% high, 60% moderate, 11.42% low with the percentage of attitudes 66.62% and 63.43% behavior. Meanwhile, for the control class, the N-gain value was 9% high, 48.57% moderate, 42.85% low and 68% attitude and 67% behavior. This shows that virtual laboratory-based online learning contributes to increasing environmental literacy skills.
