Abstract
Penelitian ini bertujuan untuk mengetahui struktur anatomi tumbuhan famili Solanaceae serta menghasilkan produk berupa lembar kegiatan siswa (LKS) yang layak digunakan. Jenis penelitian yaitu Research and Development (R&D) menggunakan model pengembangan Borg & Gall (1983) yang hanya dilakukan sampai tahap kelima. Hasil penelitianan atomi menunjukkan bahwa jaringan penyususn akar, batang, dan daun tumbuhan famili Solanaceae(P. angulata, C. annuum, S. melongena, S. torvum, dan S. lycopersicum) relatif sama. Akar tersusun atas jaringan epidermis, korteks, danj aringan vaskular. Batang tersusun dari jaringan epidermis, jaringan dasar, jaringan penguat, dan jaringan pengangkut. Namun, pada batangC. Annuum terdapat trikoma multi seriata. Pada batangS. torvum,S. melongena dan S. lycopersicum terdapat sel idioblas, trikoma stellata, dan trikoma kapitata. Daun tersusun dari jaringan epidermis, palisade, dan bunga karang. Pada daun P. angulata terdapat stomata, sel idioblas yang berisi kristal druss dan trikoma kapitata. Pada daun C. annuum terdapat stomata, sel idioblas yang berisi Kristal drus, trikoma multiseriata dan trikoma multiseluler. Pada daun S. melongena dan S. torvum terdapat trikoma stellata dan trikoma kapitata. Sedangkan daun S. lycopersicum terdapat stomata, trikoma kapitata, dan trikoma uniseriata. Hasil penelitian berupa pengembangan lembar kegiatan siswa (LKS) mendapatkan nilai validasi dari ahli media dengan persentase 91,76% (sangat layak) dan ahli materi 72,22% (layak) serta persentase dari uji respon guru sebesar 80% (menarik) dan siswa sebesar 82,32% (sangat menarik). Sehingga dapat disimpulkan bahwa lembar kegiatan siswa (LKS) struktur dan fungsi jaringan tumbuhan famili Solanaceae layak untuk digunakan sebagai sumber belajar siswa SMA kelas XI IPA.
This study aims to determine the anatomical structure of family plants Solanaceae and produce products in the form of student activity sheets (LKS) that are feasible to use. The type of research is Research and Development (R & D) using the development model of Borg & Gall (1983) which was only carried out until the fifth stage. The results of anatomical studies showed that the infusion tissue of the roots, stems, and leaves of the family Solanaceae (P. angulate, C. annuum, S. melongena, S. torvum, and S. lycopersicum) was relatively the same. Roots are composed of epidermal tissue, cortex, and vascular tissue. The stem is composed of epidermal tissue, basic tissue, reinforcing tissue, and transporting tissue. However, in thestem C. annuum there are multi-serial trichomes. On thestem S. torvum, S. melongena and S. lycopersicum include idioblast cells, stellate trichomes, and capitate trichomes. The leaves are composed of epidermal, palisade and spongy tissue. On the leaves of P. angulata there are stomata, idioblast cells containing crystal druss and capitate trichomes. Inleaves C. annuum there are stomata, idioblast cells that contain drus crystals, multiseriate trichomes and multicellular trichomes. On the leaves of S. melongena and S. torvum there are stellate trichomes and capitate trichomes. While the leaves of S. lycopersicum contained stomata, capitate trichomes, and uniceriata trichomes. The results of the research in the form of developing student activity sheets (LKS) obtained validation scores from media experts with a percentage of 91.76% (very feasible) and material experts 72.22% (feasible) and the percentage of teacher response tests by 80% (interesting) and students amounting to 82.32% (very interesting). So it can be concluded that the student activity sheet (LKS) structure and function of the plant tissue of the family is Solanaceae feasible to be used as a learning resource for high school students of class XI IPA.
